Very impressive!!! Once you get "used" to it, grab the performance box and get on the list!!!
I AM on the list ...have been since 2006. I actually did much to help the Pbox/Dbox become mainstream around here. I set up a 6speed group buy with VboxUSA a while back. Trust me, I have always been a prolific supplier of my data....on those rare occasions I have had a running car
I shared data from some 50+ drag runs and much more GPS based data. I dont need much prodding to get the data out there. The car isnt leaving AZ without some prelim 60-130 numbers and they will get posted, good or bad. Trap speed will take a bit longer since a 1/4 mile run in the AZ Summer heat is useless. I will wait til I get home to MI or maybe sooner if we do a EVOMS group track day somewhere with a nice track.
As for the turbos, they are the new Tial alpha series. They are 30/76s...well, sort of. They do have a custom high flow, high efficiency billet wheel on the compressor side...

Are those stock heads with aftermarket cams or GT3 heads with GT3 cams. Obviously one path is significantly more expensive than the other....Please do share :-)
Actually, both paths are expensive. These are custom turbo heads with larger Ferrea int/exh valves, 9K springs and retainers, custom exh cams, stock intake cams....
Yeow, that is pretty decent! Not sure why not additionally tune for C16 and have a backup file to run that. Maybe it's not possible to do that? I'm able to get C16 for $585 a barrel if that's any incentive.
Brad, I actually have two files to an ECU. I will most likely get a backup ECU since I would like 4 files. The pump gas ECU will be the 630+AWHP file, although we will work on improving this file next week, and a more linear 1 bar file for the roadcourse. The 2nd ECU will be the sledghammer file with slightly different boost and redlines.
As far as the C16 goes, we all know there is a long history with this car. Todd did not build it and as such doesnt want to push a lump he does not have firsthand knowledge about. Hard to fault the logic. If it grenades in his facility he is going to get some egg on his face. That would not be his fault and it would not be fair if it happend to lay it at his doorstep. That is why it hasnt run over 7500, had aggressive timing, or C16. We are going to raise the redline a bit when I am there towards the end of the week, but MS109 is all this car is getting..... at least until the winter
We definately need to get together. Me , you and Tim(colorinc) would be great fun at Mid Mich or Gingerman.
incredible power band. The way that Hp curve was rising I suspect that if you raise the redline to 8000-8200 you might just hit 800 without doing anything else.
I highly doubt 8200 is going to happen but we are going to improve on these numbers next week with a higher redline. How high is an open question. I am going to stay at EVO for the day with the car on the dyno. Todd said he would show me how this is done and how certain changes affect the performance of the car both on and off the dyno...
It's almost like you knew what you were talking about. So far these turbos seem to be the real deal, probably the only good thing coming out of MI these days. I have to go up to Lansing to the Sec State next month to get my plate for my truck, I will stop by Owosso and you can see your handiwork up close....
That chart is amazing. And, knowing you have a lot more space up top. Just amazing.
Enjoy and be safe.
That is one fast machine. The thing's really a mixture of much of the best in the world.
What does it feel like on the street if you have driven it at all yet?
Jeff
Jeff, there is definately much more in it. The turbos are far from dying at 7500 thats for sure. I will not be down there til next week ,but Todd did drive it home tonight and said it is very docile off boost. He said his wife could drive it. That means Joe and Tom could probably drive it as well He said psrt throttle response was excellent and it hits very hard, but did not push it real hard yet.
Great to see such a terrific result and moving along so fast now.
Can you give us a rundown of the internal and external spec as it now stands?
