Default How much boost can you make in first gear?

On flat ground, not using the brake pedal, etc, how much boost can you make in first gear? I am mainly interested in numbers from a completely stock car or just with small changes, but most upgraded cars probably have too much of a traction problem anyway.

Well, when my car was "mostly" stock. I got about 15psi right at redline. Was just chips and rebuilt/shimmed WG and cat delete.

With stock exhaust and WG, I think most are lucky to see 12-13psi.

Anyone with a 100% stock car care to comment? I am only making 8-9 psi in first but 10-11 in 2nd and up. This is with stock everything.

The cv is probably whats limiting your boost in first. I was able to do 15 psi in first mostly stock with an mbc and chip

Mine's basically stock with chip and accuboost being the only performance mods I've got on my car. I can make 11-12 in first...and in 2nd...and 3rd....and etc. I've got a Tial to go on sometime soon that should fix that limit.

Mine is stock with a bad WG and the CV is still in use. I make ~7-8psi in first, 10psi in second, and 12psi in 3rd and up. However my boost will always taper off to 4-5psi by 5000RPM, so I am shifting short all the time.

With the engine fully warm, I get 12-13 psi in first.
