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.

Bryan trapped 130 a few times I think. Of course experience of driver may be the difference, but the car itself should be plenty capable.

Hopefully we will find out. It should run good. The trick will be finding the sweet spot of launching the car. Big tire with a twinscrew is a delicate balance. Needs more RPM to keep it from bogging, too much and it will blow tire.

LOL, the funny thing is that if it was an auto, no question the car would be damn fast at the track. The damn manual adds a lot of variables to it all.

Side note - Yesterday at the RR event, there was Two Mustangs that ran well and one which was JShoots Boss. Built motor, boost and a built auto and it ran well all day long going to the semi-finals. All the other faster cars there going into the late rounds - Vettes.

Who won each class?

**Zeek** · 05-19-2014, 12:21 PM

Delrin -GT500 won B class
Vic - Grand sport won A class

It was a dramatic ending, no surprise there. Vic and Lance (both Vettes) raced in the finals. The break out speed was 163mph, both cars ran 163.xx with Vic running the lesser break out speed making him the winner.

Sean B from TrueStreet came in 3rd (not breaking out) racing a Z06 with a 100 shot on it. He drove his ass off all day!

Delrin came back to win the other class in his red GT500. He tried to melt the damn thing to the ground though after making a pass at 111mph with no water in it. lmao.

What happened to JRod?

**DirtyD** · 05-19-2014, 01:06 PM

I've only heard him say "I'll be launching the piss out of this car." which was another reason he wanted a taller rear gear. lol

Glad that RR went down without a hitch. JShoots Boss is a beast. Drag is what limits him.

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.

Doh!! Crazy fucker. 155-158mph with wet tires. That's nuts! haha.

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.

**Midnight11** · 05-19-2014, 07:03 PM

Vic ran a best of 163.xx both vettes at the end broke out
