About two years ago the Vortex Ram Air Induction System was created for the new generation 1997-2004 C5 Corvette. This system has proven to have the highest horsepower and fastest times at the track. Corvette Fever acknowledged this by publishing a three-page article on it in their January 2000 issue. This system is now also available for 1990-1996 C4 corvettes.

Hi---I recently installed the Vortex Rammer on my 98 C5 in place of my Granatelli twin-flow intake-I am a tuner and have tuned over 1000 cars & trks using EFILIVE and have logged hours and hours of data---
I am pleased to say i had excellent results to prove how better it works--
1st I forced the ECM into closed loop all the time so i could log the fuel trims up to 4000 RPM's, to see if the engine was asking for more fuel to compensate for the added airflow produced by the Rammer---All my fuel trims prior to the Rammer install were at "0" or slightly negative--I set the logger to read in MPH in the rows and RPM in the colums and the data to record fuel trims--
At 38 MPH the data suddenly shows a + trim of 9.2 (bank 1) and a + trim of 9.6 (bank 2) !!!! Clearly proves that the ECM is correcting for leanesss to compensate for the added airflow produced by the Rammer at speeds starting around 38 MPH !!!!!!!!!
Wouldn't have believed it if i didn't see it for myself--So after re-enabling the PE table it also shows a leaner AFR at WOT which I adjusted for---Can't wait to take it to the track to see the improvements-- THanks for a great product----Tom
