FWIW, we made 310whp/310lb-ft on an mildly modified EVO IX today. It had a full 3" exhaust, no cat and an HKS intake. This is on 91oct. Unfortunately, we ran into issues with the tuning laptop so we didn't get to finish the job. By the looks of it, we should be able to wrap it up on Wednesday. But so far, so good. This is one spectacular turbo. Peak boost is 23psi, falling off to 19psi by 7500rpm. Graphs to come on Wednesday...

 

Nice!

 

No boost controller?

 

The car still uses the factory boost control system. No MBC or EBC.

 

This is impressive!

 

thats crazy I cant wait to get my IX

 

That sounds great...is Shiv changing his stance on the factory airbox for the IX or was this just how the particular car was configured?

 

You can bet your left nut that Shiv isn't going to change his views on the factory airbox. Great numbers!

 

damn. 310 on 91 thats almost enough to go into the 11s. on 91!!

 

David,
Since Shiv got put in "time-out", he should have plenty of time to come to Denver and get us (Donour and I) tuned!!!

 

I don't think the numbers would be much lower with a standard airbox and the hf drop in filter.

 

If at all??

 

Man I want a IX.

 

I would still be curious to see.

 

i love my IX. cant wait til shiv works his magic on it
