Very nice. Mine isn't very accurate on the amount it produced because the clutch let go but it pulled 652hp/582tq at 20psi with the 6765 and .96 ar so that new 66 wheel is a beast. You are also on pumpgas so that's nice as well! I can't imagine what the spool would be like with e85. I gained about 500rpm on my setup with it.
What boost controller are you using? what is the spring pressure set at before using the controller?
also, could you post vids with how that exhaust sounds? I'm using a cutout but I'm starting to sway towards going back to a free flowing exhaust so I don't have to mess with anything. I just want something that isn't ricy (rattling and cackling) and not too loud.
Thanks for posting this.

really dosnt look like the turbo is falling off at all either that turbo is amazing for the size............................. damn i need to decided what to do come tax time lol i dont see why we cant extract even ounce of what those turbos can put out on our platform, heck supras are already exceeding what they rated for lol
that wheel makes me wanna send mine in just to have the better wheel lol

AEM trueboost14.7psi spring, there is a little creep most likely due to the wastegate being a little small for the system and due to the fact that it is recirculated but no biggie.

Will post some sound clips once the **** weather passes over hear, the exhaust note is not ricy at all, very deep and growls but not obnoxious.
Just what Vince said, there is still quite a bit of room to play before this set up is maxed out, so I am happy with the numbers being so high and still having it be a conservative tune.

What size is that wastegate? I have an MVS which is 38mm for my 67mm turbo. I don't see boost creep at all on those graphs. If there is any creep I would say it is due to the exhaust backpressure instead of the wastegate. I thought I had a small wastegate because mine wouldn't go below 11psi no matter how light of spring I put in the wastegate. I changed out my exhaust and the problem instantly went away. Since you are running 100% of exhaust gas through the pipes (recirculated wastegate) then you have a higher chance of backpressure.
I don't see creep though so i wouldn't think twice about it.
Jerry, they are pushing over 700hp on stock block supra's with the 6266. That's what Reid pushed on his at least. We are only .5 liter larger so it should be similar. Considering the turbo is efficient up to mid 30 psi and it is at 600hp with only 18psi It has quite a bit more potential.

I now remember that is what Vince did say, that it was most likely caused by the WG being recirculated and that it would probably be the actual spring pressure if it was open dump. Oh well it rocks the show and that is waht matters to me)

To clear up on the boost creep stuff...
I got a call from Vince on Thursday when the car was put back together and the first few runs were made. He told me that there was boost creep, 11psi spring was going up to 14psi. This was a first and I couldn't really think of a case where this was an issue (35+ kits out there now). I thought about it some more, called Hal to see if he had seen anything like this with any of the kits he tuned (since he tuned a few of them)...and the answer was no. I then sent Vince an email.....saying that there may be a problem with the gate itself.
Since tial now sends all the springs out with the waste gates, it is up to the customer to install whatever spring is needed. Since customers don't install waste gate springs every day, there may have been an error made, so I thought it would be a good place to start looking for a problem. I also found out that the owner of this car also had boost creep issues right from the get go, on the stock block.
Vince sent me an email a few hours later, saying that there was a hole on the waste gate diaphragm. So problem found...
R/T tunning did not have a spare diaphragm around for the MV-S, and since the customer was on the way to pick up the car, a Comp 40mm gate was used to get the car tuned. I refunded this customer the money for the Tial MV-S gate since if was of no use, and it is going back for warranty repair/replacement.
In the end, another happy BP customer.

Correct the WG had the 8.7psi spring installed with the stock block and I would get between 9.5psi - 10.8 psi with that spring which must have something to do with a defective WG
still though with the new Turbosmart WG and 14psi spring the car pulls 15.5psi, it was explained to me that this could be because the WG is recirculated and would most likely not occur if it was open dump...either way the comment below could not be more true)

traction is an issue but I guess with that much power traction is something that is a tough one to get right.

What are you using for tires? I was running Mickey thompson 305/35-18 drag radials. I could only get my camber to -1.2* and with 650hp I was lacking quite a bit of traction on the street.
