Horsepower

[EvenFlow]

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.

[violator6090]

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

[violator6090]

[Squirrel Nuts]

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.

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.

[violator6090]

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

[z06transam]

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

[Squirrel Nuts]

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

[Ilovefirebirds]

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.

[HotBoys09]

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. 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.

[Squirrel Nuts]

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.
