Yes
Those were at different boost levels starting low and working the motor upward. Akram is an authorized Protomotive dealer/mechanic and he can give you more insight if you need it.

Thank you for your compliments. I believe the trick has to do with the cams. These cams allow the motor to breath much better which makes more power at a lower boost level. I think Todd and Akram have a few more tricks they are going to try on the heads after Supra Nats.
Cheers

They are modified GT3 styled intake as well as exhaust cams. I am not certain on all the details but has a very unique idle.

Rob,

Now all you need is a sub 5 second 60-130 time and that should shut Craig's pie hole.

Admitedly, I do enjoy reading Craigs posts, so I am not sure if that is a good thing.

Robert,

We had GT3 cams redesigned,profiled and center drilled from billet (intake and exhaust) for a turbo motor instead of the normally aspirated GT3 motor as the stock ones are designed for. We shared all our specs with Todd over a year ago. I'm curious how close your motor's cam specs are to our specs? I'll give Todd a call.


By the way ..........very nice numbers. Thanks for sharing

Looking at the turbo map of the GT35's, at 1.5 bar you are at the bottom of the most efficient island. At 26 inches or 1.76 bar you are at the next best efficiency line in that island. You would have to go to 35 inches or just over 2.3 bar to max those turbo's out with your present displacement and air flow.

The highest we have been thus far is 30 inches. It really loves boost :-)

Rob,

There are the drama-queens and then there are the guys who just put up the numbers and aren't interested in the drama. Thank you.

What I would like to see is some video and etc... since this has to be an INCREDIBLE sounding beast Please do have someone with a cell-phone or a camera do a little video so that we can hear the music... That's half of the magic, as you know, and this monster should be an entire orchestra to the ears.

Markski has a "famous" video which reads.... "At 200mph you have no friends..." and indeed with so much horsepower.... you will have no friends.... and it was good. I look forward to someone sponsoring a similar video effort on your behalf.

All the Best,

SY
