When do you guys get full boost by? I've heard anywhere from 3K all the way to 5K with most being around 3.8-4K. With a hi-flo cat or restrictive exhaust you should get full boost a little sooner.

 

I get full boost around 4300 RPM's and a few hundred RPM lower in 5th gear. This is with the stock cat and the easily reversable non-sequential setup.

 

My boost kicks in at about 4K rpms with a midpipe. Very laggy for stock turbos IMO! I have ridden in other non seq cars with very similar results.

 

I am full boost between 3200 to 3500rpm depending on the gear and weather. DP and MP. Complete conversion with clipped turbine wheels to help control boost creep, and enlarged WG.

with ported wg and some porting to the turbo manifold itself..id get 12psi by 3600 in 3rd
oh that was after a good bit of playing with the profec-b

 

My primary turbo has a bad seal and isn't working but my secondary (working for both) spools up between 3.9 and 4.1K - what was weird is one day like 2 months ago my car seemed like it was amazingly fast - I took it out for a joy ride - watched as I had full boost by 3K rpms!!!! Weird, huh. I need new turbos!!!!! DP, hi-flo, N1
