ct26 efficiency

[gsxr141]

just a quick question. i searched but didn't come up with a definite answer.
what's the max boost recommended for the stock ct26? i'm sure you can just crank it up, but at what level does it just make hot air?

Do you have any mods? hardpipe? exhaust?

If not, don't push it harder than 8-10 PSI as the car is choked up. Now if you have free flowing exhaust, you could push it to fuel cut.

sorry. i have lex/550's, bic ddp, full 3" exh, k&n filter, hard i/c pipes. i dyno'd it at 16psi, but it falls off to 13 or so after 5k rpm. my max hp was at 5500. i've run it at 17psi on the street, but it feels like the ignition system might be the next weak link. other than that, it pulls hard right to 6k rpm.

13-15 PSI is close to the top I'd push a stock CT26. Now I run my 57 trim at 16-17 PSI almost daily.

cool, thanks. i'm actually pretty happy with how it goes considering the few mods i have. ultimately i'd like to get one of alberts turbo's and shoot for 450 wheel. that should be plenty.

hrm... I've got free-flowing exhaust (was put together with the idea in mind that it'd be hacked up shortly to fit a s300-56) but it's a bellmouth 3" all the way. and for some reason it feels like 8-12 psi is nothing but hot air. I almost feel that 8 psi is making more power :-/ I'll probably dyno it here shortly just out of curiosity, also to see what the power is at before upgrading to standalone and s300
