R85

Made a final pull, maxed out the compressor and ran out of turbo...27 lbs boost
561 whp
445 lb ft torque

spiked to 31 lbs,but kept bleeding down to 27-28 lbs but couldnt keep flowing the volume at high rpm's with a 22 lbs waste gate spring and boost controller set to max and even with a manual one on there as well. Compressor side is only like a 61mm.

Awesome numbers Greg. Hopefully in about 2-3 weeks, we'll see what my 40R can do at those levels. What boost controller are you running?

I'm impressed!!! NIce numbers!!! Got a couple questions, if you don't mind... What was your RPM where the torque curve starts to flatten out? What was your max RPM? Is that a ball bearing turbo? EGTs?

Thanks Dee, yours should make good numbers once everything is done. I am running a Greddy Type S (basically the old profec B with 3 *****).

III Gen X:

rpms peak and flatten around 4400 rpms which is where it makes full 27lbs boost, so I see 27 lbs at around 4400-4500. We pulled to 8500 rpms. It is a NON Ball bearing turbo. EGT's peaked around 1390-1400 degrees F. with probes tapped in each runner before manifold...they were very even from front to rear rotor housing with that Xcessive Lower intake manny. Thanks for the compliments

thanks Rich. You will like it, are you going to do the 4 top feed setup that is an option, or just cap the other bosses off and run traditional top and side feed setup?

I bet you'll probably go with the 42, 45, or 47? A GT47 would be awesome, but you'll have to get a new manifold made for it and it would probably not fit under the hood. But you could just cut a hole in it. That's what I would do anyway. I think you should pm me with what you are thinking. I won't tell.
