I still say the greater torque of the viper makes a difference. You can't start our cars in 3rd gear, they can.

This is from a roll though.... Torque has less to do with races from a roll... power to weight ratio and aerodynamics are the key to top end races.

THE RESULTS

This is a post by the owner of the Viper. I'm quoting it because I don't feel like typing all of it. I was at 17 psi on BFGs. Viper was on road race slicks with the Venom 500 package going from a 40 mph roll:

First race: When we let out the Viper was two cars ahead and it was obvious things weren't going to change much if it continued. Viper was still in forth gear. I believe Roy thinks the Viper left a little soon. We didn't discuss this part but I think: Roy started to jump early and then had to hesitate to be fair and it cost him. Another words I think the Viper was on time at go and the little bobble at the start cost Roy some time and maybe some boost. Roy thinks the Viper got a little jump on that one. When I say he started to jump early.....it was just one of those things....you gotta be ready, it wasn't a cheat jump or he would have not done the double take, he would have kept going. Hard to tell but that start could have been better. The second run I think Roy got the jump but not because he went early, maybe the Viper slept. Whatever, the rx7 was almost...maybe a whole car ahead very quickly. It stayed like that through second and third, then in forth and the very beginning of fifth the Viper had pulled back up to the back of the rx7's front fender and was still pulling when Roy let out. I really wish it had gone farther because before fifth was done the Viper would have pulled ahead.
In Roy's defense it was a location he was not used to and the protection of the guard rail/wall had past by and there was traffic to the left of the painted area at the end of the wall. I would have stayed in it if I had been in his lane but I know the traffic flow much better at that spot. Roy will give his take but this is pretty close. Both were from a 40 roll.
I hesitantly agreed to one win for the rx7 and one win for the Viper, but I did agree. Boils down to: Both cars are fast and damn close. A totally stock Viper would get spanked by at least three cars. A totally stock rx7 would get spanked by....never mind
We were going to do round three, we exited this road and at the end of the exit ramp there was a stop light and when turning left to cross the overpass to re enter some old man in a 95ish firebird runs the red light and side swipes the Viper in front of the rear tire on the quarter and door. Finally got him to pull over and it looks like there are no dents or dings, only whiteish looking scrapes and residue. Some of it rubbed off with spit and thumb. I believe they will all buff out without going to primer. Close call !!!
I guess now we'll have to let him put on some NOS and I'll install my 3 bar map sensor!

It was a cool run and the Viper runs strong. I was proud of 'lil 'ol red! It impressed a lot of people.

Did anyone notice the 7.2 @ 93 mph? That sounds a little off. Did he get on the brakes or something? The 7.2 part sounds right, but the 93mph part sounds like a stock GTS (118-120 1/4 mile traps) and a 7.2 ET *in general* is in the 98-100mph mark.

maybe you can find a local video/camera store that'll convert it to mpeg or avi for you? a few web sites advertise the service, but probably easier to find a local place.

Roy, drop a copy of the videos with Art at the Dynolab. I'll pick 'em up next time I'm there. CD or tape is best. I don't have a mini disk reader.

Good job Roy! Sounds like some really cool races Where were you guys running at? What was the top end looking like? If you shifted into 5th then I am guessing 160 or so. Glad you guys didn't get caught!

We were on a cross bridge. We got up to 135-140. I'm also still waiting to get the vids up!

In order to beat that car, you are going to need to be in the optimum gear and be ready to grab the next gear - it will be no picnic - mess up a little and it is over.

He has two things going for him that you don't - torque and slicks. He is going to hit the throttle in his optimum gear and he is GONE! You are going to deal with traction and RPMs, whereas he will not so much.

I would give the race to the Viper because the situation. The race could swing to the RX-7 IF IF IF the starting speed was more like 60 mph - then the race would be more tilted to the RX-7. Wheel-spin is not good!
