The Swift Guide for a quick v6 F-body

This guide may or may not be challenged by the opinions of others, but who cars.

First of all we have OVERDRIVE!

Why i havent seen most of you guys use higher stall torque converters is beyond me. Its been proven over and over that a higher stall torque converter will increase performence noticeably.

Gearing, this is an issue with most people, but from what many have told me in the past by the word ont he streets. 4.11's are most likely the best choice for our v6 or you could try try 4.56

LSD is a must if you dont already have this get it now!

Better traction is always good, lower control arms, torque arm if you can come across a cheap one, aftermarket springs.

Any simple weight reduction is great as long as its not from the rear end to much.

I seriously think its rediculous that anyone would buy supersix heads. the 98+ 3800 v6 heads flow enough, porting them and your intake would be the just as good as buying whole new heads.

IMPORTANT...

air/fuel tuning, engine cooling, air/exhaust flow, good spark are all essential in running good performence. Upgrading Fuel Pump from stock is always a plus.

I see people using aftermarket MSD's which is non-sense. the stock MSD is well good enough.

Cams, this is a subject it seems not many like to get into because it requires real thinking.

Depending on your setup how much air flow/fuel and exhaust is coming and going certain cams may not respond well, its up to you to find out what you are running and which numbers will benifit your setup.

Running your 3800 v6 with a good

well flowing intake/tuned fuel deliveryfuel/well flowing exhaust to match intake/matched cam/4.11 gears/higher stall torque converter/reasonable traction mods, this will take your car into low 14's

add low boost supercharger or turbo... you just made a low 13 second car do a little more work, now you hit 12's with a v6.

Hell.. Headers, high flow cat, cat back, intake, gears, aluminum D/S, and a 75 wet shot and you in the mid 13's.. Get some suppersix motorsports package with a nice nitrous cam you will be in the 12's..

13's aint to impressive, especially with nitrous.
why race a 3800 v6 at the tracks thats only in the 13's?. its economy engine. there is 4 bangers making 11's at the tracks

Swift, It seems like you are making general assumptions about the 3.8 engine. Do you have any real experience with making a 3.8 fast or are you just saying everything you read? I am curious, What does your v6 run at the track? I am sure its nothing impressive just by the way you talk about mods. You dont know what it takes and you are just pointing out the obvious and everything you read about other peoples cars. So why should anybody take advice from you?

My motor is stock.. All I have is full exaust, intake, gears, and a 75shot.. dropping 2 seconds off your time with just 4 bolt ons thats impressive.. By the way what does your v6 run anyway?? I see you are going to get a LS1.. let me know when you do so we can run.. I will put the 50 shot back in just for you!!


:D

i thought those were supposed to help lowered cars. so i shouldn't bother with them since i got Eibachs?

Your weight is off a little there, buddy. I think it's a little over 2900 w/o driver. 3500 w/ driver :D lol j/k

Also like magnus said, 3.8 doesn't see performance gains at the track, but 3.4 does. My 3.4 saw performance gains, thats for sure. On stock coils and wires too.

4.11 might be the ideal gear for track use, but not street. 3.73s would be a nice street gear and still give you a decent highway RPM in my opinion, others might like their RPM lower of 3.42s.
I think it's about 400rpm difference per gear change..

I think nitrous'd cars like to see a little taller gear, but I'd have to ask my dad to be certain about it. I remember talking to him about NOS before and taller gears like 3.23s being used.

2300 pounds? My @ss
Best N/A weight W/O driver 2956
Best N/A weight W/ driver 3177
When I spray add 24 lbs per bottle and I run 2 bottles. I change from drag radials to et streets

relocation brackets help both. they help you get more traction by increasing the angle of the lca's going towards the ground. when u lower a car, the angle moves away from the ground, so to achieve the old angle, or close to it, relocation brackets or adjustable lca's are required.

something important should be noted as well. most of our 1/4 mile time is achieved in the first 60 ft. This is because our car's are heavy, big, rpm limited, and are built to make a lot of torque. dropping the 60 ft. times will make the 1/4 times much lower. gears, tc, traction, ect. will all help this.
