Horsepower

Ive got a 99 firebird, V6 automatic. Does anyone know exactly how much HP I will gain with new headers, filter, and so on... What are some more sure bets for HP gains.

that would probably give u about 30 hp...hypertech programmer is good. exhuast is good

that would probably give u about 30 hp...hypertech programmer is good. exhuast is good
you said in another post that i/h/e would only produce 25hp in a v6'er

yea between 25-30

yea 25-30 for i/h/e then did u forget bout the programmer thass anotha 15hp and lb/ft ... 40-45 total.

I still think 40-45 hp is a little much for filter/headers/exhaust/hhp is a little much. You MIGHT get that at the crank if you are lucky, but definately NOT the wheels.

Its just a lot easier to get a turbo kit and put it on for some nice HP/TQ gains. :p

there is no way that they give 25-30 horsepower. by those numbers i would have over 200 horsepower on my 3.4, i would say that it adds more like 15-20 at most. enough to allow a noticable difference but not enough to drop significant seconds on the time.

Do A Full Exhaust Headers Cat Back All That. Intake , K&n, Under Drive Pulley Kit. And Short Throw Shifter And Youll Be Pretty Quick. Then Later On.......... Supercharge It !!!!!!!!

WOW, what a noob. First of all most v6's had auto's not stick. second of all you listed k&n different from intake, k&n is a company not a product, pulleys dont do much, gears are where the speed is along with a nice converter of course.

haha u dont have to be such a dick about it. Intake, Headers and Exhuast are always nice but u are right, a new gear with a converter is one of the biggest speed differences for the money

And Yes Pulleys Are Big Youll Get About 15 Horse Out Of Them. And I Didnt Know What T Was Stick Or Auto But Short Throw Helps If Its Stick. And K& N Makes Filters And They Make Intake Kits You Chose Either One You Wanna Do. So Fuck You Sixer Boy

First of all fuck you not me, you buddy. Til I'm done with my "Sixer" I'll be able to contend with stock and lightly modded LT1's so I deserve more credit than you. Second of all you shoulda said intake or filter not buy intake and k&n, second of all 15hp from pulleys is big time bs. maybe on a trans am at the crank but no way on a 3.4L, not even at the crank. Stick to what you know

This is supposed to be a post not a stupid argument. To tell you the truth, there isn't much you can do to a V6 for significant HP or Torque gain. You might want to try looking for a turbo b\c i still have yet to find a super for a V6. But i would go with the cheap upgrades for now such as K&N (intake system or just filter), programmer, torque converter, etc. You might just want to throw in some NOS for quick cheap HP gain.

I agree with Squirrel Nuts, the 15 hp for pulley on a 3.4 is BS. And man you'll get much much credit from me if your car does keep up with modded lt1's. What have you done....and what do you plan to do, I'm interested. Oh and whenever someone asks about getting more hp and tq, and people say turbo or super, I laugh in my head. :screwy: Because one they are sooo expensive. Decreases the life on your engine, and little things go wrong with them. Even from the factory, I had to replace the turbo on my daytona 3 times. Also for beginner tunners that is deff. not the route they wanna go, it's for people who want SERIOUS power with serious money...same with NOS, but not as bad.

Hotboys, I have ordered a venom400 chip which should add 25% of my power, it's garaunteed or money back, deal at local store but anyways... *ordered* venom400 chip
rk sport headers
magnaflow catback w/ gutted cat
SLP cold air intake
*ordered* a High energy cam from CompCams w/ lifters & full timing set
*ordered* 3.82 gears w/ Richmond 10 bolt rear
*ordered* 2200rpm torque converter
*ordered* BMR handling package (lmperformance.com)
*ordered* BMR traction package (lmperformance.com)

All that should put my 3.4 up to 260hp and 286lb/ft plus the converter and gears so I should be movin once all is installed, i need 385$$ more to afford installation but thats only 2/3 weeks of work so it wont be long.

Wow man, that's good. And I would esstimate rolling with LT1's def. But if not, you'll smoke them damn stangs!! Show some pics whenever you gt it all installed or something...cause I think it's a really cool thing when people make base model vehicles faster then the "Fast" version. Good luck... :evillol: :smokin:

so u have a 3.8 firebird and a 3.4 firebird? im only sayin that cause your logo has the 3.8. if that is so that you have two firebirds why not sell them and get a TA

VERY good question... :evillol:

oh my god you guys and these fucking six cylinders.wheres the big dawgs forums at? dont waste your money trying to get power out of it sell the car and get a 5.7. its just a waste. i used to have a 99 camaro 3.8 and did a little bit of stuff to it but its not worth it . there are too many 4 cylinders out there that will spank a v6 camaro or firebird. they are much lighter and more nimble. plus they have strong internals running with the turbo's. my buddies 98 gst runs low 12's just from a small 16 g turbo and catback exhause and a front mount. now that will fuck up your 3.4 or 3.8 sixer. dont blow your money on the 6 cylinders go big or go home!

agreed...

Thank You

Save the $$ you are going to spend on cam/springs/lifters/etc and put it towards an LT1 with the tranny. You can get a engine from a salvage yard for a good price. heck...even on the web. that's what I would do and you don't have to tell the insurance co that you have an LT1 in the car.

Decreases the life on your engine.

Only superchargers decrease the life of you engine b\c they act as a parasite and feed off the engine while a turbo does nothing more than run off exhaust. It is like making whatever waste is coming out of the engine into power. Also, did you know that most superchargers actually hold around 200 horsepower by themselves, but when you hook it up to the engine and pulleys and such, it take anywhere from 50 to 100 horses to pull the belts which knocks you down anywhere from 50 to 100 horses. Turbos don't do that. All they do is run off exhaust while supers feed off the engine. I do agree about things going wrong with them though. My friend has a 2003 Mustang GT with a super and 2 weeks after he had it installed, he had to take it in to get it repaired. 3 weeks later, it happened again. Don't know what actually happened but from what i can tell they aren't the most reliable upgrades out there.

I have a 3.4L, remember when i posted that i found out when the engine was swapped because it died in 99, it had a 3.8 put in, well i was wrong, they put a 3.4 in i just didnt change my signature yet. By the way I DONT WANT A 5.7. Insurance is twice as much and mine is already high cuz im only an hour and a half from philly. Plus think how cool it would be to run with lt1's in a 3.4....:smokin:

:banghead: :banghead: :banghead:

ALL of that...I knew when I was 13...but thanks for the info. I meant by the added stress...

And squirel nuts...the fact that you have a 3.4 instead of a 3.8, I retract my previous statement, no LT1 ass whoopin going on there. You'll need alot more then that to beat em...sorry.

super chargers are easier to install and easier to maintain and understand. putting a turbo kit on a car that doenst have one is the worste thing to do and actually doenst give it that much power. iput a vortech g trim aftercooled o my 99 and got 470 hp at the wheelswith 7lbs of boost and can go up to 10 wit my other pulley . my buddy put the ls1 motorsports single turbo on his camaro and only got a little over 300. of course superchargers thake away power from the engine but it all goes back after putting it on and you get like 75% more. you only get maybe 25-35% more from a turbo kit. plus installation is much easier on a car than turbo kit. you get into oil tap for turbo, intercooler, all the custom piping, new headers for turbo then boost controllers and all kinds of fucked up guages. supercharger you hook it up nd go to get more boost change the belt, and your done.

Yeah, want to tell the guys out here who watched me run a 5#(on boost gauge) STS turbo kit with my 4#(on boost gauge) P1SC(before the current pullies) and we both ran side by side, shifted at the same time and continued to run side by side from 70-125ish.

Turbos have more potential, but for at least 1/2 again of the price, and the headache of putting them on our cars...its not worth it IMHO.

Zo6, you're a fag. "Go Big or go home" my ass. Anyone who can significantly increase the speed of a V6 F-body commands respect. Shut the fuck up with your K & N shit, you sound like a fuckin ricer wit that shit.

fuckin ricer .

I am not familiar with all these sayings but just for my knowledge, what exactly is a ricer?

haha seriously?...well i see it as any car with a 4 banger and a retarded sounding exhaust

haha seriously?...well i see it as any car with a 4 banger and a retarded sounding exhaust


Rice = stupid sounding exhaust/body kits/rims/stickers all over the car. Cars that LOOK fast but run 16+ second 1/4 miles.

I love the import guys who their car looks stock(or good with a nice set of rims and a very mild set of ground effects that don't stand out)....but thier car runs.

My one friend Nick in San Antonio is like that. You look at his car, its got a nice set of G/Es which you don't really notice unless you look at his car and a nice set of rims(no..not bling blings). He put a 1.9 Type R engine in it with a turbo and an air/water/air intercooler(tank out back to add ice :lol2: )

I had the pleasure of riding with him one night when an LT1 guy on the highway thought he was oging to stomp Nicks Civic. He pulled 2 cars up....dropped about 1/2 car behind the guy...then proceded to pull the guy for another car or so...back and forth for a while. It was pretty funny. The guy in the LT1 didn't think so though :iceslolan

To answer your question. A ricer is a derogatory term used to describe a kid who saw "Fast and the Furious" one too many times and thought that if he bought a shitty Civic coupe, fucked up the suspension by dropping it (I'm sure Honda engineers worked hard on the suspension for people to go fucking it up and thinking it's "ill" to have your ass end bounce up on every pebble on account of it). They think adding a muffler, yes muffler, not exhaust system, that's a waste of time cause the muffler is cheaper and it just sounds cool, but most people think it sounds like a weedwhacker.

Yea, stickers all over (if it's a Honda it'll say "Type R" or "V-TEC" on it wether it has those engines or not), nasty rims, maybe an odd paint job, and if they're actually into making their car faster they'll have put a turbo in, but usually they are the lowest end kind that won't do much to your civic or GS eclipse.

I've actually seen a kid in an Altima with a huge wing and "GT-R Skyline" written all over it. Now, the GT-R is legendary near-supercar, one of my friends had one imported (he totalled it, but the engine was saved so he switched it into his new 350Z), a crappy Altima is no skyline. THAT my friend, is rice.

Just because someone is driving a Japanese car doesn't make them a ricer though. Although most Honda kids are. Accords and Civics are not meant ot be fast cars, but these kids swear they are. Now someone driving a Supra, 300ZX or 3000GT is driving a fast car and is most likely to not go fucking it up with horrible and useless mods. So those guys are cool, but the other day I was driving out of the mall in my friends LT1 Z28 and two cars wiz by me. A Neon SRT-4, and a Volkswagen GTI. They have to stop at the light cause it's heavy traffic, and I end up right next to the neon. Now, neither of these cars is Japanese, but they are both based on the idea of "tiny car w/turbo=fast), and yes, the SRT-4 is fast, 0-60 in 5.9 sec, mid 14 quarter mile, but the GTI doesn't compete. Well, I thought about showing these guys a thing or two about speed, but my friend told me it wouldn't be worth it, plus the area was full of heavy traffic and notorious for cops. Now, when they took off again I see that they're both pretty much even all the way to the next light. Which mean that either the Neons driver sucked, or the GTI driver had done extensive mods to his car, and my girlfriend drives a GTI, and I know there is not much short of replacing the turbos and buying a new computer to make that car lose a second (or two for that matter which you'de need, to run with a stock SRT-4) so I imagine the neons driver either must have sucked, or it really was just a NEON with the SRT-4 badge on it and an ugly wing(it was not stock).

THAT my friend, is rice.

How do you think a stock WS-6 LS1 Trans Am would fair against a 3000GT or better yet, a Supra?

1997 Mitsubishi 3000GT VR-4 0-60 = 4.8 1/4 mile = 13.6
1998 Pontiac Firebird Trans Am 0-60 = 5.1 1/4 mile = 13.4

1997 Toyota Supra Turbo 0-60 = 5.1 1/4 = 13.6

would be close but with the ws-6 im sure the TA would win

Hey Seraphin Dont Get All Pissed At Me Because I Know My Shit. I Had A Sixer And I Know The Potential They Dot Have. They Are Way To Heavy And Underpowered. So You Wanna Say Fuck Me Bro You Got More Problems Than Me If Your Rockin A Fuckin Six Cylinder Piece Of Shit . When You Wanna Run With Me Let Me Know Bitch. Bring It!!!!!!!!!!!!

hey z06 stfu seraphin dint say fuck you to you i did, and ill say it again fuck you. you have no idea wut ur talkin about and no one listens to what u say. How can u not have respect for someone who takes an engine a whole hell of a lot smaller than yours and can run with yours??? Lemme put it in perspective...you pull up to a red light and sitting right next to u is some asshole and his swedish girlfriend in his brand new porsche 911. you spent 20-30k for ur car he spent 120-130k for his, you both rev a bit and then u both go like hell, u win, he feels like a dipshit....see my point yet???

thats a stupid ass way to compare it. the guy who spent 120-130 k on his porsche 911, still has a porsche and obviously a hell of a lot of money and could probably care didilly squat about a race against a firebird. he could just go buy one himsef if he really gived a shit and put 50 g into it and spank everyone. i hate when people actually think that a guy who owns a 100k car gives two shits about a race. if anything he would just be impressed and go on with his rich awesome life of luxary

but no no your right id prolly kill myself after losing a race to a firebird in my awesome porsche, cause clearly my life sucks now

Um, Z06TransAm, you're a dumbass. Ilovefirebirds, to answer your question.

a 98 WS-6 T/A averages a 0-60 of about 4.7 and quarter mile of about 13.3, maybe quicker.

A Supra Turbo of that same year would be about even, but the T/A has the advantage if it's a good driver to good driver comp, seeing as it's my opinion that it takes more skill to drive the T/A, and the T/A is just a pinch faster.

and violator6090, the 3000GT times you posted are just a tad off. A 99 VR-4 does that quick a 1/4 mile, but it's stock 0-60 is about 4.9. Any year before 99 doesn't break 5 seconds. I should know, i drive a 93 VR-4 after getting rid of that horridly slow base 3000GT (0-60 in 7.8, 1/4 mile in 16), And I'm waiting for my WS-6 once I sell the VR-4, so yea, out of those three, the WS-6 is the quickest and the fastest. Now, a plain ole' Trans Am will have a bit more trouble with these two, but nothing that a few cheap mods wouldn't fix.

Also, yea, one of the pleasure of driving any kind of american muscle car would be to show up some rich guy in the Porsche or BMW next to you. Or better yet, that ghetto kid in his mommies Lexus IS300 who thinks his car is "Dope" or "ill". Yes, Porsches are nice, and so is any expensive car, but I'm sure that a poorly educated porsche owner who thinks he owns the fastest thing in the street finds out his 911, (or funnier yet, Boxster) is not as fast as a car costing a fraction, he won't be happy.

I got nothing against rich people or porsche owners myself, but some of those guys do deserve to get embarrassed, honestly. And yes, I do know a kid personally who's dad bought him a blue 911 turbo and he thinks he's fuckin god, so yea, the allegory is half true, some people are undeserving of fine automobiles like a Porsche and DO actually give two shits about a drag race from one light to the next.

So, when I get my Trans Am, It will personally warm my heart to destroy every kid out there with a civic, or Lexus IS, or fake BMW M3 (cause round here that's the "IN" thing), and you dirty insurance claims investigators and crooked Lawyers with the Porsches or Infinity G35's, watch out cause if you dare take on a pissed off WS-6 with extra kick, you're gonna get owned.

That's all.

i totally agree that i love to burn cars that are expensive like that too. But in the long run who wouldnt want the porsche instead? i certainly would and not a boxster those things are trash a v6 bird stock could prolly beat them. also 4.7 0-60 for stock ws6 is a little high i think, but then again it may be automatic which actually have a little faster 0-60 and 1/4 miles

oh and those faggots who have porsche's and Lexus' handed to them just need to have their asses beat personally as well. after you race them and beat them u need to hit the brakes in front of them get out and punch them in the face a dew times just to let them know who's boss.

You are correct. 4.7...not likely. Not a stock car. low 5s are the norms on an LS1 Fbody

With just a lid and cutout, I didn't have to many problems with BPU+3 Supras/300ZXTT/3000GT TTs(only off the line for the first 100' or so if that)/RX7 Turbos(this one was my personal favorite :lol2: cause he lived in my apartment complex and talked trash to me the week before).

dude i never put down imports first of all because i would definately take a supra or a rx7 or a skyline over most american cars. i know what they do my deal is with you now so if you got a problem with me lets get out of this fuckin forum and settle some shit you know how to get ahold of me BITCH

Will You Guys Shut The Hell Up!!!!!!! You Sound Like Little Babies!!!!! This Is Supposed To Be "help People Out" Forum Not An Abuse Forum!!!!

yeah but half the people that sign up for this forum do it to just start shit like saraphin and squirrel nuts.i get ont his sight to try to get some info and all i get is a responce from some fucker with a sixer that doesnt know what a ls1 is

Get over it. There are tons of people in the world like that.

Hey zo6, fuckface, I do know what an LS1 is, it's an all aluminum 350c.i.d v8 that puts out about 315hp at the flywheel. It's fast as hell and i wish i had one, even though i prefer LT1's but that's a whole diffrent arguement. Just because you have an LS1, that doesnt mean you're all high and mighty. It doesn't mean you know what you're talking about. Just because i drive a v6 doesnt make me know any less than you. Not evry1 can afford an LS! or LT1 upfront, or from an insurance standpoint, so stop bitchin out sixers, they're still decent.

LS1s are 350s? :screwy: Seems to me like they are 346s. Most LS1s put more out then 315 fwhp. Heck, my car stock, put 292rwhp which puts it in the 340-345fwhp.

I agree on the whole LT1/LS1 arguement. Stupid and pathetic.

The stats i listed are straight from GM, but i agree they do seem more powerful than 315 at the FW.
