Jonathon's best chance to beat Zeek would be at the track forcing Zeek to attempt to launch the car without breaking the rear in the car. Otherwise he will have to leave soft and try to chase him down before the traps. By limiting the distance, it gives the Stang a good chance. However, on the street, from a roll with doing a full pull, the Stang is at a serious disadvantage due to power to weight, gearing and aerodynamics.

From a roll, Zeek NA to Jonathon's boost, it should be a decent race providing Jonathon has traction (which he should on those tires). The distance of the race will determine how many cars Zeek will put out front cuz the Vette will undoubtly backdoor the hell out of a blown Stang.

Zeek on spray, forget it. Someone should call the Homicide Unit cuz there would be a murder going down.
Johnathan has swapped to 3.15 gears, so he will be able to hang in boost for a good while...may or may not help though, just throwing that out there.

Trans gears also play a big role in that as well, not just rear end gearing. A lot of 5.0's need to make a gear switch when going boosted because with stock gearing will either make you run out 4th or force you to throw 5th before the traps which either way slows you down. Switching to the 3.15's will certainly help him in that area.

I think he said that he should be able to cross traps in the 130s in 4th, but not sure where in the RPM in 4th.

Mathwise, based on the tires he has (which I think are 275/60/15 M/Ts) and the gearing in the MT-82, 130 would be about 6500 RPM, so he has enough gear to stretch 140 in 4th, maybe even 145 if he runs it to 7200-7300.

I have serious doubts that he will trap 130+. My guess would be 125-128 depending on the temp and DA.

His car ran good. Barely got eliminated in the semi's. Fast lil rotary car. First time I've ever seen a rotary car make that many passes and not break.

It broke BTW. He was leaking coolant all over the runway. But kept in the race. Vic said it was spraying on his rear tire.

Kind of goes to show you the advantage the vette has. Jshoot's car makes what mid 800 hp and the vette Sean was driving was around 720hp. Jshoot's car I believe went a best of 155mph and the vette with 100 less rwhp ran a best of 157mph. So if nobody believe the 100hp difference it was proved yesterday at RR.

I routinely trapped 133-134 with mine, running 3.55 gears. We set the rev limiter to 7400 and I crossed the line at 7200 in 4th. I personally think the 3.15 gears are going to hurt the 1/4 mile trap speed a bit, and I'm guessing it will be in the mid to high 120's. With the right tires though, it will be a LOT of fun on the autobahn.

3.15 gears, my tire size, transmission gearing, 7000 rpm will allow me to spin 4th gear up to 139 MPH. That's perfect for the trap speeds that this car will see. Although my car has not been weighed, it is not the average pig of a Mustang and has almost all of the light weight parts in the right areas. Steve, I believe your theory is flawed and I will prove it wrong. If for some reason I don't beat Zeek, which I highly doubt, I will stand corrected.

Why do you believe it to be flawed? Have you expierenced something different racing it? Ive spent a lot of time out and believe to be a pretty solid formula.
