I have an Evo 9 that is running great at 25psi. But I want more out of the car, but I don't want to blow up the block. It ran 11.9's early this year on an average 60 foot at 117mph. I know it has way more horsepower if I turn the boost up....but I don't want to leave parts scattered on the road.
Only interested in staying with Pump 93. E85 hard to find.

What would be the suggested parts upgrades I would need to run 30 to 35 psi boost and would get me in the mid 10's....but keep the car as a daily driver.

Here are my current mods:
AMS Intercooler
AMS hi flow cat
AMS Cat-Back Exhaust
AMS Upper Intercooler Pipe
AMS Lower Intercooler Pipe
AMS Small Battery Kit
Spark Tech Ignition
Kelford 272/272 Cams
Walbro 255 LPH Fuel Pump
Turbosmart Blow Off Valve
Hallman Manual Boost Controller
Exedy Triple HD Race Clutch
ARP Head Studs
FP Black Turbo
FP Intake
1000cc Injectors

Right now the car runs great, sitting in traffic, a/c on, etc. So don't want to mess up a good tune....but I realize I will need to retune with the new parts.

thanks for the help

 

For that much boost with no e85 your going to need meth to cool the cylinders to avoid knock. Do you have any idea what your current duty cycles are at with a single walbro on those 1000cc inj?

 

Yeah.. 30 psi is just pushing it on pump gas... Anything above that is just risky, more than it already is... As rjfg suggested, a methanol injection kit would be necessary to run with pump gas to achieve 30+ psi.

 

Unfortunately I don't have much information. I bought the car about a year ago from someone who had built the car more for show....but put some "go" parts on the car. He had it tuned by Atlantic Motor Sports...seemed they did a nice tune...as the car drives very well. My previous cars were tuned by David Buschur...and I went the E85 route with my last EVO, but its too much of a pain to drain the gas each time I want to switch between 93 and E85. I was hoping to just stick with Pump 93.

The car had old dyno sheets showing 467whp. But running high 11's tells me the car is not making much more than 400whp...so I am assuming its because of the conservative 25psi. I am hoping its not the driver

 

Things you need:
-Double pumper
-C16 tune or E85
-Have your car re tuned for 30-32 psi, it will hit really hard
-Consider an ultimate gear ratio trans from shep to meet your times

 

Slicks or drag radials is a cheap investment and will cut your 60ft and ET's.
