so got my evo 8 ready and prep for the big dyno tune.. boost leak test resulted negative.. ready on da dyno.. a very sad day when the car only produced 336 whp and torque 385 wid all these mods.. any suggestion guys of what cant it be.. any suggestions? these are my mods..
Stock Turbo
HKS high powered exhaust
Skunk 2 dp and testpipe
greddy spec b MBC
ACT XTSS and Prolite flywheel
HKS air intake
HKS bov with upper piping
walbro fuel pump
defi boost/oil/exhaust gauge
forced performance cams installed by icsperfromance
Aquamist methanol injection with gauge installed by icsperformance

can it be possibly the turbo is shot? or waste gate actuator needs to be replaced? pls help
car has strait pipe no catalytic converters. i don't know..
thank you

 

Which cams, how much boost, and on what kind of dyno? How much timing was it running and what AFR's? Was it knocking with too much boost? Lots of questions we can help ya figure it out Post up the dyno plot and list the above info and we'll go from there.

 

no knocking but timing was very slow.. the car was pushing weak..
forced performance 264/264 cams.. full boost of 100% 30 psi on the greddy spec b MBC and not on a mustang dyno..im sorry but no copy of the dyno sheet which was very disappointing..

 

Also what kinda dyno...

 

any suggestions? recommendations?

 

who tuned it....

 

sorry when you asked what kind of dyno? what are the differences?

 

Big Al, at ics performance.. he suggested the turbo is shot.. or possibly the wastegate actuator..sorry i'm kinda new to this dyno stuff and i need to learn more about it..and im ready to learn what causes such problems..

 

lol I hope its one of the two things you just listed.

 

might be the wastegate.. .cheack and make sure that you dont have a line loose or off.. hope u find the problem

 

Do u have 9.8 hot side or 10.5..

 

your making 30psi and you think the WGA is shot? Is it taking too long to spool or something?

Maps might help too.

 

Dont think its wastegate....maybe do a compression check. How many miles on the turbo? At what RPM's does it feel like the car hits full boost?

It seems silly but different dynos read different numbers. Different brand of dynos, along with different correction factors end of with alot of different results.

 

i put down 300 on a low reading mustang dyno at 26 psi mods in my sig... everything u have except Ic pipes and meth......

 

key word for this one STOCK 8 TURBO
