Re: throttle body spacer?

Good post rick and good read. The data on page 5 was good enough for me. See below. My '97 GTP is too old for an intercooler and I'm satisfied with its performance as is.

BTW - Also, I run the ZZP 72mm ported throttle body and my Eaton M90 Gen 3 blower is S ported. The SC pulley is 3.0". IMO it doesn't hurt and everything helps. It is not just one mod but the totality considered together.

The throttle body’s temperature dropped an incredible 69°F!!! Not bad for an inexpensive easy to install bolt-on product.

The most impressive finding to me wasn’t the temperature of the throttle body but the temperature of the supercharger. The heat gains to the air through the throttle body must have been significant prior to adding the spacer. We dropped the supercharger body temperature by approximately 29 degrees Fahrenheit! This should greatly reduce knock in our quest for high performance, and allow us to put more power to the wheels on those hot summer days at the drag strip.
