No reason to do the Throttle body mod on a non turbo. You will not gain any HP, and can potentially give yourself cold weather drivability issues.

+1. I had the mod done to mine (have since swapped it out for a stock TB) and would not go back. It does not offer much besides crisper throttle response in an N/A. Feels about the same on the butt dyno as well. Mine was also hard to start when it was cold and would die at stoplights, but I also had the AWS disabled. My .02.

Gains from doing this mod are more apparent in the TII model. I think there's a whole thread in the racing subsection N/A performance.

cold start sucks on a modded TB, i have driving the 7 when its to cold and im late for an appointment.

hehe i just did the tb mod but i left the cold start stuff on so no starting problems and no idle problems and i ported it a little. the throttle response was so much better when you punch the gas it jumps for idle to like 4 grand almost instantly and when cruising i can punch it in pretty much any gear and it just goes not like before when there was always a slight hesitation i love it will never go back to having secondary butterfly's
but to each his own

I swapped a modded TB for a stock one, I hated having to keep my foot on the gas to keep the car idling (s4 T2).

i dont understand why you guys all have problems with the throttle body mod because i dont and love how sharp the throttle response is

I have never had an idling issue with the TB mod... cold or hot??? I think you need to either adjust the idle screw, the BAC valve or crack the throttle plate set screw

Its called a dashpot, it is supposed to stay there and you'll never have idle problems comming to a stop. Not everyone does the same tb mod and it definately shows through on the results. I have ported mine but retain the secondary butterflies. I have a standalone and the butterflies are triggered at a certain pressure to open (custom setup) and it makes a world of difference cruising at high revs and driving around town. You'd never know I had an 8.5lb flywheel with lightened rotors (8.5:1) other than how fast it revs.
Like any modification, its the attention to detail that shines through.
Several writeups exist, but I have noticed that they all are different. I never actually followed one when I did mine. I just did what I felt was best for what I had. I am a diy kinda guy + I have a few unmolested tbs' that I can switch out if I want.

i noticed..... i think im gonna give it a try. better throttle response is always good and i was planning on taking out the cold start anyways. thanx everyone

I'll have to find my pics. I ported my tb on my 86 NA and i noticed a little gain. I also don't have cold start problems. maybe i'm just lucky. I tend to do alot of things people say won't help but with my car almost stock and i garuntee it'd do 14s in the 1/4. i think every little bit helps.

im not sure i like the way it described through RR directions.... does anyone have there own pics and instructions for a S5 N/A

specialop

I used RR's instructions and breezed through the project. I spent about an hour tuning, but the engine now runs better than before the change.

Red_Rabbit86
