This is a true statement. All the grand am race cars are HR heads and shamus old car is with a 4.0 stroker with an HR head also. The jun cam car is probably runner up.

Track vids tomorrow unless i fail tech, may need a firewall for the tank.

what type of piston and rods does your car have?

yep stock rods, pistons, crank, bearings, timing gear, valves, springs, lifters, vvel, ports(nothing is ported). the only internal changes were the cams and removing the oil pump.

There was some slow secret sauce poured into the trans to help with the higher rpm shifts tho, eat that TSM lol

Elmo370z 11-02-2014 09:55 AM

geez, the stock internals don't mind that many rpm's?

G37sHKS 11-02-2014 10:59 AM

Im just curious, since your budget and engine was open why you didn't go for stroker to get the most out of it?

valpozguy 11-02-2014 02:34 PM

Correct me if I'm wrong, but I always thought that hi rev motors work better with shorter stroke?

Based on my research (JWT, Unitech, the NISMO engine-builder with Kelly Racing), with replacement rod bolts both the VQ35HR and VQ37VHR are both safe to 8800rpm (although the jury is still out on running the VVEL that hard for sustained periods - there is no real empirical detail).

With OEM rod-bolts, I'd be reluctant to exceed 8000rpm, but that is just me.

Remember, NASCAR engines run 9500rpm and more for hours and they are all >3-inch stroke.

Just got back gonna load up the video latter tonight, really need to adress traction issues. Pulled 2.328 60ft and still trapped 113.1 at 13.3. It has got the power to go deep 12's but i might as well be launching in second with my 60ft times.

So the stock Pistons/rods/crankshaft etc can handle 8800rpm if the rod bolts and oiling system are upgraded? Probably would want to use hr heads as well.

Man, that sounds absolutely beautiful.

Nice trap speed. What tires were you using and how was the track prep?

1slow370 11-03-2014 12:24 PM

Track prep was ok tires were stock nismo, and i only got 3 runs in it was hella busy. Probably could have knocked off more time if i could have gotten more runs in. I was shaving time off as i was getting better launches 14.4-13.9-13.3 i could have gotten into the 12's with more runs but it really needs better tires. Really was surprised with the amount of wheelspin it was so much harder to get a good launch than when it was stock.
