Hi guys....went to the dyno and here it goes...:

evo9:
cams 280, boost 28psi, full exhaust 3", blow off tial44mm, stock turbo, filter, pump gas, reflash.....:

made 350 hp at 6000 rpm
350 torque at 4500 rpm
made opinion on this please...

 

what kind of dyno

 

93 Oct?

 

28 PSI??? your car HATES you if that is your full mod list

 

^werd.

 

(office space boss guy, bill lumberg voice) uuumm yeeeeaaaah... 28 psi on the pump stuff is a lil bit high.
Im gonna need you to work this weekend...

 

28 psi on pump gas? Which pump...the one at the track?lol. Those are quite optimistic numbers. Stock IC and piping too?? Gotta be a record.

 

DYNO JET .....has walbro fuel pump.(forget to metion that )..... it hits 27 to 28 for a second at certain rpm but drops fast to 26,24,23, and stays at the end in 22 psi.... and it is on pump gas 93 oct.

 

Was the car tuned for 28 psi of boost and has the car been logged to make sure it is running safely? Also what type of dyno was this on?

 

whoa just whoa.

 

the one reason you have your boost jumpin is that the stock braided hoses' on the ic pipping exspands when you spool up and the increase in volume causes' a drop in boost pressure buy the injen front mount kit and the upper ic pipping kit

 

No, don't buy the Injen pipe kit.

I recommend turning the boost down. Your spike to 28 PSI in probably causing a bunch of timing to be pulled, which defeats the purpose of running high PSI. Turn it down to something more livable like 21 PSI and get rid of that horrid taper as well.

I'd recommend getting the Samco intercooler hose coupler kit. Also, the 350 WHP you mention doesn't mean much at all. What was your baseline power on that same dyno?

Also, don't you have an Evo 8, not an Evo 9?

 

The stock turbo spikes like that regardless of your IC piping, its because the turbo is capable of holding that much boost but only at lower rpms. As the rpms increase, the stock turbos ability to hold boost lowers to roughly 21-22psi by redline. I don't know if I can even tune my car not to have any knock at a peak boost of 28psi. Most guys that run 28psi on the stock turbo and 93 octane have an alky kit. The most you usually see people SAFELY setting their peak boost to on 93 is around 23psi, on average.

 

post up the dyno sheet.

bring the boost down a bit, to like 23 and see what you can do with timing

 

I run 1.6 bar of boost at 6300 feet elevation on 91 octane, safely I should say...
