Here is your "identical" setup at 9psi minus the Head Gasket

 

What does the 3mm gasket drop the compression down to?

 

I would try to get a little more fuel in there at the top end, that could be dangerous granted its Stoich but definitely upping pressures and heat, I would run it a little rich. Sounds like the oil could be losing you some power too

 

with a 3mm headgasket you will lose anywhere from 35-50hp. also tell your tuner to richen it up a bit like around 11.7. and then all is left is to up the boost to make up for the gasket

 

I think it's a combination of your stock clutch and the gasket. Those numbers do seem a bit low, and your AFR is a bit dangerous at WOT. Mine is in the mid 12's and even that is high, hence me needing a retune also

The Inline kit is more of a street kit, and is going to show more conservative numbers. Still, I thought you'd hit 320-330 on 10psi.

I think with a stronger clutch you'd see some nicer numbers, and some fine tuning. The gasket is there for you to boost higher so, it's time to up the boost

 

9:1

btw chef I give you permission to 'transport' my car to the dyno from wherever it currently sits ; )

 

i'd like to hear your thoughts on why inline pro is a street kit............

 

 

What make InlinePro's kit a "street kit" ?

 

ps....my first dyno run #s were 313rwhp @ 9psi boost
