mustang v6 3.8

[plasmatic]

guys i need help.I just got my ass handed to me by a grandprix gt 2004.Do those cars really have 200hp? I don't have mods but I expected to win but lost bad three tims in a row.What can I do to mod my stang so this doesn't happen again.thanks

well, turbo or supercharger are the easiest fixes. other than that you can go with a bigger cam, intake, exhaust, headers, and some other things similar. one way to make a good difference right away is also to put bigger rear end gears in it, like some 3.73s or 4.10s. right now i think you either have 3.06 or something close not sure what that size is, or you might have 3.27s. you need to be willing to spend money though. its gonna cast more than 50 bucks. and do you have an automatic tranny? thats probably a big factor in why you lost, the manual 3.8 stang is quite a bit faster. and yes the grand prixs can be pretty quick. i think some of them are supercharged?

i believe there are also stroker kits out there for the 3.8

he has 2.73 rear end gears. they have 193 hp stock. some things u can do now is a cold air intake,underdrive pullies,gears,a comp. tuner and exhaust. if u want more u can get a cam(if u know how to install it)throttle body and a ported upper intake and maybe a throttle body spacer. what if ur price range right now?

it wasnt a supercharged grandprix but it was a gt which has 200hp.my mustang is standard but the grandprix still beat me pretty good.A lot of ford guys tell me that being my car is RWD and very heavy its not going to be easy to beat a 200hp FWD lighter car.My budget is about 1500 for now for mods.I guess you can't beat them all but as long as it wasnt a civic

The 4.2L V6 in the F-150 is the same block, so yes there are stroker kits My 01 is a 4.1L, I didn't bore it out to make that extra .1L. But I did add a cam and roller rockers alot of port and polishing work.


Right now, the largest stroker for the 3.8/4.2L block is 4.4L's. I have heard of one person hitting 4.6L but had oiling blowby issues.

If anyone is interested in stroking or making serious power with the the 3.8L/4.2L blocks, you want to go to this site for the parts.

3.73 gears, a cold air intake, and underdrive pullies should get u a keeping up or a lil faster then the grand prix.thats a pretty good budget, do u want websites for mods or r u not sure if ur gonna mod it or not?

[TheStang00]

are u sure about it having 2.73s? i was almost positive they were one size larger... and i was already aware of the hp rating... also, your car isnt that incredibly heavy, about 3000 lbs. grand prixs are not light cars. just because a car is rwd doesnt mean its heavy either, that grand prix is actually heavier than your mustang, atleast based on info i found the curb weight of a 02 grand prix is 3390 lbs. i think one problem you run into is that im guessing your car is an automatic. cause if it was stick you should have beaten that car.

If you stating he is making 193hp, that means he has a 2001/2002 V6 mustang, and they came with 3.27 rear end gears. the 03/04 got a slight bump in displacement to 3.9L's and they are 200hp, and 230ft-lbs of torque. They average curb weight is 3200~3400lbs for the V6, depending on options.

BTW the 99/00 V6's made 190hp and 220 ft-lbs of torque.

i thought it was 2.73 gears but im not 100% positive. he said his mustang was a 5 speed so i dont know why he got beat so bad.

his grandprix is a 2004 and it has 200hp.It does make sense that he beat me though cause even though my car is standard he's still got a lot less power lose than me.He's FWD and im RWD so his 200hp turns into a pretty close wheel horse power where as for mine I lose how much to my rear wheels.I know my v6 is slow compared to most but I didn't expect to lose that bad.My gears are 3.27 by the way.

silver stangs said he put down 172.8rwhp and 206.8rwtq when his was stock at 190 at the crank. i dont see how a pontiac could do much better then that. if u have a 2002+ ur probaly puttin down about 175 at the rear wheel.

i understand your thinking, but i dont think its correct.like neato said, if you have a stick your probably only losing 20hp or less. an auto tranny car will lose way more than that. being rwd doesnt hurt you all that much, it really doesnt. infact its better than fwd for getting off the line. im tellin you he cant be putting much if any more than 160hp to the ground.

How much is it to get those new gears? Also, cold air intake is fairly cheap to get isnt it?

Hello:

This post was linked from the Grand Prix forum. Needless to say, this caused quite a bit of chuckles.

Anyways, to answer your possible questions on the stock GP's.

97-03 The GT has the 3800 and puts out 200HP at 5200 RPMs. Engine also produces 225 lb-ft torque at 4000 RPM. Same specs for the 04'.

If you took on a GTP, 97-03 models carry the supercharged 3800 and that puts out 240 at 5200 RPM and 280 lb-ft of torque. 2004 GTP puts out 20 (260) more hp, same lb-ft torque.

Oh well, like one of our members stated, "They don't call it Pontiac excitement for nothing!"

Have fun putting new gears in and such.
