Going to push a different direction with our car for now Options

[Fastbird]

It's been a while, but it's time to make some changes to the setup of our swapped car. Remember that with a SMT6 piggyback and some other work, the stock CT26 made 249 HP and about 260 TQ to the wheels in Summer of 06. Over the winter I noticed that the CT26 will actually put out 18-20 PSI and HOLD IT TO REDLINE with good enough air.

So here's what I'm thinking (and it will all happen relatively soon):

AEM EMS for complete tunability w/GM IAT and 3 Bar MAP (AEM or GM).
Water/Alky Injection full time, boost referenced and tuned accordingly.
AFM Delete in favor of a better intake tract.

I figure by cooling the intake charge via the Methanol, the boost should hold on a little longer. I'm curious to see how much farther I can push the Ct26..........

There's a dyno shop here in IL about 15 minutes from me that is reasonably priced that I will be frequenting.

Thoughts? I'm sticking with the stock injectors for now as the meth injection will be partially like an added fuel also as well as a cooling tool.

The stories that the ct-26 is "maxed out" at 16psi are myths - plain and simple. The turbo is past its most efficient operating range but still will give additional power.

its a myth to a point. the higher you go with the ct26, the less gains youll start to see past 15psi. even with a big fmic, and water injection, you can tell you are just pushing that stocker too far. most people just turn up the boost based on feel, and never have the proper tools to monitor whats going on. next thing you know, you start seeing 10 threads on mr2oc about how much the knock sensor sucks cause they just blew it. when in reality they were just pushing the ct26 too far.

honestly, my recommendation for people with a stock swap is to keep it at 13-14psi. it seems to be the sweet spot for safe a/f ratio and no knock response.
