DUDE! Super Doopper! Possible as good as it gets for these cars. I envy this ride.

Actually what I should have said is "YOU WIN".

Duke

Hehe, thanks.

Having some ISP problems so I uploaded the charts here as well:

Something you want to keep to yourself ?.

Duke

No I just haven't come around to answer that yet
I use stock valves. With my setup (turbo, compression, boost level, power level etc) I can run reasonable EGT which in turn saves the valves.

Thanks.

Stock cams? Any headwork?

Duke

Yes and yes.

Re: headwork - How beneficial do you think it is for the 16valve?

toddk911

Are those new charts new runs at higher boost? 1.15 bar broke 600whp???

Duke

I would say it's beneficial but not necessary. My work is pretty minor.

I don't understand this?
450 Ft/lbs (609 NM) with a GT35 through a .82 T3 hits almost EXACTLY where I would expect at 17 psi given his head and a few other things he has disclosed?
Obviously, we look at the torque curve here, judging boost, only the inexperienced will even give the HP a second look regaurding boost/turbo/rpm - but this follows with a nice balance too.

A GT40 ball bearing is a 750 HP compressor, this engine will see close to 500 RWTQ with that compressor, all other things equal, in my experience.

What numbers did the guy that did the 3.2 put down?

Duke

A lot of torque, but not a lot of power. I haven't seen a 3.2 built with good breathing.

Congrats Duke. You have definitely set the bar on what can be accomplished with a proper 16 valve setup. I think you realize, this makes you a target for a few 16 valve guys . 16 valves with higher compression is the way to go. There are plenty of manufacturers that are already doing this. It's one thing to run 8:1 on a 2 valve head, it doesn't make much sense to run so low on a 16 valve head.
Beautifully done, congrats again and good luck.
