Vortex Ram Induction System for the 08 Corvette results. First, How do we get our results? All the runs are done on the same day and within 30 min of each other. The first 5 runs were done using the stock system. Second 5 runs with the Vortex Ram Induction System. Another 5 runs with the stock system and yet another 5 runs with the Vortex Ram Induction System. All the runs were on a 08 stick Z51 Corvette with a Magnaflow exhaust. All runs done with the hood down and a high flow fan in front.
Results on stock system between 378.4 RWHP and 380 RWHP
Results with the Vortex System Between 390.4 to 393.2 RWHP
This is with no programming done to the system. LTFT were between -2 to -4 and wide open AFR was 10.5 to 10.7 That's about 17 HP gain on 10.5 AFR
If programming is done and AFRs are set to 12.7 to 12.9 gains should be between 26 to 30 HP not including the ram air effect.
This test before programming was done to insure performance results without havingany check engine issues
