LS2 RX7/Stock 243's/Fast 92/Street Heat Stage 2/V2 Si@8psi
Some may remember this RX7 that I posted a dyno results thread of before. Those results were from when the RX7 was cam only with our Street Heat Stage 2 camshaft and made 448rwhp/430rwtq! I was very surprised how much power it made for such relatively mild modifications and camshaft with only 8.5 degrees of overlap.
The car was a freaking bottle rocket at that power level and would run door to door with cam only C6Z06's and made 408 4th gen F-bodies look like fools. He had also been 11.1@126mph in the 1/4 and a couple 6.90-7.0 passes@100mph. Well that wasn't enough power for this customer of ours and he wanted more!
It was time for a modified A&A V2 Si supercharger kit to make its way onto this RX7. He left the cam alone as it wasn't a bad choice for a centrifugal supercharger and here is what he was rewarded with!
Here is an overlay from his cam only dyno pull to his cam only V2 Si pull
Look at all that new power!
I think it's safe to say that this thing is a certified rocket ship and that if you have a C5/C6 with under 700rwhp or F-body with under 750rwhp you better think twice before messing with this one!
Also the tune is super safe with AFR in the low 11's with only 14 degrees timing. There is at least 30rwhp left in the tune alone, but I'm pretty sure that this is enough power for now in this 2700lb. rocket ship!

Car came out great guys thanks again for the amazing tune. Jonathan is the man!! Car pulls very strong. As far as traction goes honestly the blower took out a lot of the initial shock and made it to feel like a traction control lol. The car comes alive on some spirited runs
