you forget to mention you are spaying alky, or are you trying to see how far you can sling a piston?

 

Absolutely irresponsible post. Do not attempt high boost on 91oct or even 93 for that matter. Someone failed to mention that meth @ 115oct must be sprayed along with this pump gas as not to destroy your motor.

 

whats the secret to letting the stock turbo go this High?

 

Free up your intake and exhaust. O2 housing, Forge wastegate, MBC, high octane or meth injection, wideband O2 meter/logging system and as much datalogging equipment as possible to keep it safe. The more info the better.

 

So the forge wastegate is worth it?...dont forget a good BOV too.

 

oops...typo ...sorry warr

 

05 EVO - 22psi on 93-94. Usually 94! When my car was at Pruven I was getting 0 knock count @ 22psi. Car feels strong! Al said that he seemed to be able to get away with 22psi on pump with the 2005s more so than the 03-04s due to the larger turbine housing.

Occasionaly, I throw in a couple gallons of 112 leaded and turn it up to 24! Seldom though..

 

You guys running over 22 PSI .....how are you not hitting MAF cut?

 

Ive never heard of MAF cut. Do you mean fuel cut? I never had any issues, of course I only ran 22psi when I got the car reflashed by Dynoflash. Before that my car was 19psi.

 

Not For long.....

 

No I mean MAF cut because thats really what it is.....its a fuel cut that happens because your MAF reading is too high and the ECU thinks the WG soliniod is broken.

 

Oh. Ive never even heard of that!

 

I am running 26psi on 93 octane and 100%Meth but it only gets that high in 4th gear. The stock 9.8t turbo doesn't have enough of a load for me to hit full boost in those gears.

Before on 93 octane pump gas I was hitting 21.9psi.

I have hit 33psi with alcohol injection. It likes to taper down tho lol

 

23psi tapering to 20 on 93 octane. A/F ratios were in the 9's on my last dyno. Having her tuned on the 10th along with a Forge actuator installation.
