Well I would say it is, the G makes less than 100 ft/lbs at that RPM.

I don't think this car was built to go to the corner store to pick up tampons for your old lady.

The huge turbos take awhile to spool up and with the lower compression it likely makes a little less power than a stock G until he gets into boost.

Road coarse car LOL. Drag/highway monster is what his car is all about he knew with the huge turbos he would have major lag.

I can't wait to check it out at Z-days congrats Rich. Also SilverG he is not on stock clutch. I know he had a spec twin disk but not 100% if that is what he is using now.

Ha stock clutch...um no!!!!

I always love the lag comments....Supra's are laggy as Hell pretty much all the time, yet they are just about the ultimate roll-on racer.

What was the boost at for the 898 run?

The lag is nothing a squirt of nitrous couldn't fix, but definitely a dyno queen as it is now. Nice numbers.

Really?

Kinda goes to show ya what crazy headflow and intake volume flow allow.....at same boost SP made 1248rwhp and were able to rev much higher(mustang dyno, and I don't care what dyno-to-dyno comparison is done, thats a big diff at same boost).

Now that someone really has crazy flowing turbos on a cosworth, I am sold that cosworth isn't worth it.

Yessir,

I get my info from "the man" himself ...... I agree on cosworth so I dont get it, hopefully (I still change my plugs in 45 min with OEM plenum) .. Some have shown cosworth gains of 40whp before and after though.. With FI.......

Well, if its the basic TT kits we mainly see on VQ's then its probably the choked down side of the exhaust wheel/compressor causing the exhaust mani pressure vs the intake pressure causing the gains seen when relieving some of the intake mani pressure when going to cosworth.

That being said, if you are running turbos that the exhaust side isn't the issue, we are right back to the intake being the bottleneck again.

GB on CJM intakes????? lol

Have you ever driven one? The E92 M3 is a torquelss wonder...lots of fun up top though. I will say a stock G packs more punch down low. A 335i with bolt ons and tune would be waaaay more fun and cost a lot less than the M3. My .02.

*edit* the E92 M3 makes peak torque (300ft-lb) at 3900 RPM (at the flywheel)... at 1500 RPM I doubt it is even making close to 250WTQ...it MAYBE makes that much to the wheels at 3900 RPM. Also Its only .2 seconds faster 0-60 than the E46 M3...thats not a lot of difference.

Sorry, that's the one I was thinking of the 335i the one with the twin turbos. 300ft/lbs from damn near idle to full rpm.

the powerband is no different than Hal's street car, the intense widebody with the 76s, or any other supra making similar numbers. Thats just how the powerband looks like on small displacement motors with big turbos.

I have a 3000 rpm powerband. same as typical greddy/gtm guys. Mines just 5-8, compared to 3-6000.

Hals street car went 9.34 with 100 less HP. The G is alot heavier, but a potential low 10sec car for sure
