I'd be interested to know which car did the quickest lap times . The Vette was slowing the 7 down in some parts of the track but the 7 couldn't get past due to being out gunned on the straights .

Cheers for that .
In light of that I would say that Bob did a pretty good job holding Jeff out . Although I know it would be really hard for Jeff to make a pass stick he would have put a lot of pressure on Bob to run a flawless race .

Where are you getting this from? Haven't we been through this like 4 times now on this forum.

Props to the RX-7 driver, he is obviously very good. That being said, without knowing the setups of the two cars its very hard to evaluate how big a difference between the drivers is. The Corvette certainly appears to have a significant power advantage on the RX-7. It's ludicrously simple to extract power out of the LSx motors, so stock block guys can make 550 rwhp with cams/headers.

Torque is a wonderful thing to have too!
I would think that engine is 375-400 hp range?

Hi Paul,

Simply amazing... I would love this in my track car.

Could i ask very nicely... for the specs of the engine?

The description on Youtube only says 13B PPort, i'm guessing NA? Based on a Renesis?

I can't believe it's not been asked.

Are we allowed to know the power now it's a 6 year bump?

Do you get many requests to build similar specs?

Thanks.
