WHats the BEST performance Mod You have done to your car..Besides Turbo, Supercharger, spray...

Just basic bolt on mods From Gearz to Pulleys basically?? Which MOD made you feel a difference??

 

Superchips programming without a doubt.

 

The 4:10 ring and pinion, without a doubt. But a noticable difference with my cat-back and X-pipe also.

 

4.10's!!!!!!!!!

 

Two words:












TORQUE CONVERTER

 

MT # 1 Customer....WIth 4:10's And at 3000rpms in 5th gear..what is your MPH?

 

I say 4;10s and pullies
WORST- Superchips / Chip

 

U didnt like the CHIP??? wow thats a first....what was wrong with that?

 

I say gears and pullies along with a good tuner

 

hey...when u installed the 3.73 gears did u notice that the car pulled much faster than the stock gears (as it should anyways) I mean...how much better did your track times get??????? I dont know wether I should go with 3.73 or 4.10

 

I didnt notice any improvement in ET or MPH all it did was calibrate my speedo had a lot of problems with it sent back to Superchips 3 times before they got it right! 1st time the idle wouldnt go below 1500 rpms and the 2nd time the car wouldnt start the 3rd time finally got it right car started and idled but no improvements at the track in fact car ran low 15s with the chip on the motor, ran a 14.99 once!! took the chip out did 4 passes and the worst run was a 14.8 best run was a 14.6 @ 97mph @ 5600 ft above sea level The only reason I left it in was that it kept my speedo calibrated! I just got tired of dealing with Superchips Ive herd that the SCT tuner is really great though

 

I don't have gears yet, or a tune, but from what I've got it's a toss up between the x-pipe and plenum

 

best was a 14.6?!! With just a cat back and K&N and I was able to get a 13.99 @ 99.98mph. That was in my 99 35th Limited Edition GT, same as you. Sounds like something is up.

 

My best is a 14.4...........

 

I ported my stock throttle body and upper plenum and went from 13.7@101 to 13.40@103. Much better throttle response and only cost me about $20.

 

My top 3

1. 3.73 Gears- cars pulls much harder in 3-5th gear.

2. Diablo Predator tune. The predator tune added a ton of mid-range torque.

3. Rear wing delete. Not a performance mod, but looks bad ***

 

gears...but I bet my mind will change after I spray the pig or cam it

 

The best bang I got for auto-x was a set of big fat sticky tires. LOL
Other than that I think I felt about the same improvement with all the engine mods I did. Hypertech tuner, plenum spacer and ported plenum, pullys, and removed air silencer with free flowing filter. Each one of these read improvments through the butt dyno.

 

My mods are listed, as far as superchips goes I bought the tuner from them and it has only hurt my track times. The SCT is the way to go. If you want better economy go superchip you want performance go with Superchips Custom Tuning! 14.080 is the 1/4 time so far.

 

just go with 4.10s. everyones doing it c'mon go with 4.10s jk. yeah i have 4.10s and i have yet to install them becuase i am not sure i have the same debate except mines between 4.10s and 4.30s.

 

Yeah but look at where you live at? I race at 5500 + ft. above sea level!! Cars dont breath as good here you come here I guarantee you'll add about sec. to your Ets!

 

gears are the best bang for the buck.

 

4.10s with a SCT Chip is the most noticeable thing you can have put in

Bolt ons take awhile for you to notice,if any,but gears will let you know they are alive and kicking

 

Gears, no doubt the best seat of the pants mod you can get.

 

According to charts I have seen, here is the approximate rpm change with gears...

3.27 to 3.73 is 250 rpm
3.27 to 4.10 is 500 rpm

 

Doesnt seem like alot but it sure feels like you've added another 50HP to your car. You know how sometimes you add or do a mod and at 1st it seems like you've gained a bunch of HP then after awhile you get use to it and cant really tell its there. With gears, you will never "get use" to them. You will always be able to tell they are there everytime a ricer pulls up beside and you weld their doors shut.

 

Now there's a testimonial if I ever heard one!

I've heard the same 40-50 hp "feel" from other's who have gears and compared race times/hp, etc.

Gears make a substantial difference!

 

My exhaust so far. I have full lenght headers catted x-pipe and catback all from SLP. Sounds mean as hell not for the weak hearted!
