Re: secondarries
Jerry is on vacation. I believe his last text was from a black sand beach in Tahiti...
Cheers,

As expected extra airflow adds power and torque, and also raises the rpm at which peak power and torque occurs. Looks like having the plenum throttles open costs about 30 lb/ft of torque at 2500rpm, I assume that if we exrapolated that graph to lower rpm, we would see even more torque loss with the Plenum throttles closed.. Both PT open and PT Closed both make the same 290 horsepower at 3900rpm. Thanks again Graham. peace Hog |

Thanks again for posting Graham. I couldn't find it as I wasn't spelling secondaries the same as the title of this thread in the search box. Graham, did you ever find that page with the bullets that illustrated what engineering from the LT5 program was used in the eventual GEN 3 LS1 engine program?
