Photos of the build for this customer’s motor can be found here.
We recently completed the 2011 IRP Chris Carlisi Memorial Engine for a customer down in Daytona Florida. Internal changes include oil and coolant passage modifications, RA Black ‘Super’ apex seals and race clearancing for high boost. Here is what he had to say:
Impressively the car put down 398whp at 13-14 PSI and 455whp at 17-18PSI. The IR Performance stage 3+ ported motor wanted more and should easily make 500 at 21-22 PSI with the addition of ID2000 secondary fuel injectors. The new engine netted 35 more horsepower than the previous at the same boost level. I cannot thank IR performance enough for the prompt service and endless customer support! I have patroned many rotary shops previously and they are by far the most honest and helpful. They take pride and passion in what they do and the results show!
