Thanks for the info on the current set up.
I wanted to zero in on compression to compare your boost pressure on pump gas to skewedtothelefts
The difference is head gasket thickness(maybe 1 point CR) which explains how you can use more boost on the same/similar gas.
My stuff was more old school with low CR and high boost levels...sometimes resulting in soft low rpm power.
Richard started playing with higher (stock)compression and kept the boost levels down to live on pump.
I was trying to give skewed some good advice and sure don't want to see him hurt the motor.
Whats your feeling on 1 octane point making a difference at 4 lbs? I'm thinkng don't sweat it but suggested he call Richard.
Far as NJ, I've known Bob Carpenter since he raced Pro Stock bikes, sometime in the 70's.
I met Steve when he was Carps engine assy guy...many years ago
If he's doing your motor, you are in real good hands...the best!
I turn wrenches for fun and to learn.
If I wanted machine work done, I'd go to Bob.
If I wanted a turbo motor built, I'd head right over to Steve's...
What is Richards target AF ratio? IIRC, he used to tune for 12.0...
My buddy has a Knecum motor in his street Busa with a lotta work...beautiful bike, bullitproof motor!
It's got an air to water intercooler and he runs around on the street with 340HP on pump gas...:)
Good to see some interest in turbo's!!!
