Thread: Big bore VVL input needed

You need to see the light and go VE-T

VE-T is where it's at.
Gotta represent....

Hahaha, the DE does pretty dang well.

I second that.
I broke my fourth gear in my B15 box 2weeks ago. I punched it in 3rd and it spun the hell out of it, pulled fourth and that was it. Got a 1.8 box and switched everything over. I'll tell you one thing, I rather rebuild the old B13 boxes anyday over this box. What a pain in the a$$ . I can pull on of those apart and back together in less than an hour but the newer boxes is a different story. I hope this doesn't happen to often.

A good 300hp N/A build will run very close to a high 300hp turbo build so i think these guys will do just fine.

yep, i can have a box torn down and back together with a new stack in less than 20 minutes. haha. The other one takes me an hour and a half. Pain in the arse.

I think what it is is when it spins like that the tires are moving like your accelerating at say 8k rpm, then you quick shift and instead of it rev matching at 6k where it would have been if you were actually at that speed and had traction the tires slow down to where in the next gear your really at about 4k so its a big rediculous shock on the trans. I can think of 3 trannies that broke this way. Every time ive partial throttled the gear and actually rode it out to where i was going the actual speed to match the rpm its been fine even quick shifting.

But yeah our tranny situations for turbo suck.

^Man that would take a lot. I would love to see this happen. JUN's car is around 275-285 or so by now, and his compression is around 14.1:1 or higher I believe.

Pump gas motor?

^This is a guess, but I don't think so. For him to build a "money maker" like that, he gotta be using more than 93.

He is on race gas.

He has a rather simple build also, makes very good power for what it is. 300hp is def possible with the right combination of parts.

He said in a post that's its in the 15s.. so not a pump gas motor. He's running like 108 oct or so. But I bet y.e85 could come close. but I also thought his was still an 86mm stroke so imagine what would happen with a 92mm crank
