Ok, the ct-26 is cheap and decent. It's worthless after 8psi tho. The T3 is hear works well. But if you use that, you use lower boost levels righT? And T3/t4 would be overkill cuz u could probably get a t3 cheaper, right? Someone clue me in on what u think the ideal turby for 5s is and why.
With a T-series, would u need a new manifold or just flange? -------------------- NASA/SCCA RX-7....currently under the knife

No, if you already know and plan for the risks, 13 psi on a ct26 is fine- it's just not economical because it's out of the turbos efficiency range- every increase of psi you get less hp- of course you still GAIN HP  , The problem is, once you're out of the efficiency range the turbo has to work much harder to get you those gains (this leads to much increased turbo wear). At one point the turbo will refuse to spin any faster (I don't remember this point on the ct26) due to a variety of mechanical reasons (inlet outlet size, spool, etc etc etc) and if you up the psi past that, you'll damage the turbo. You won't hit that point at 13 psi tho  Basically, what it comes down to is that even if you up the psi to some insane amount on the ct26 (say, 20-30) you'll probably be at the hp level of 15 psi on a bigger turbo (but your engine still has to handle 30 psi!!) Not to mention that even with a smaller turbo; it still takes a long time to build up to 30 psi. A larger turbo would spool up to the 15 psi mark faster. After you've built up your engine to handle 20 psi- would you rather run 20 psi on a smaller turbo, or a larger turbo? |
