I have some good news and some bad news about the Ptuning tC.
First the good news...we've added some major front-end grip to the car by utilizing the extra clearance on our front flared fenders to mounts some seriously wide toyo R888 tires. Now for the bad news...after checking all the fluids and sparks plugs to get it ready for Summit Points tomorrow, we noticed that the plugs in cylinder #1 looked a bit suspicious. So we decide to do a leak-down test on all 4 cylinders; cylinders 2, 3 & 4 were perfect, while cylinder #1 didn't look to good. Let's just say we'll be running a 3 1/2 cylinder turbo engine tomorrow at the time attack.
We believe that the damage was done at Nashville, when the wastegate line melted and caused the motor to momentarily overboosted to 30psi. If we hadn't run the meth/water injection that day, i'm sure the motor would have had detonated when we lost the wastegate line. In any event, we've gone too far with the changes we've made to the car's suspension in the past few weeks to back out now. All we can hope for is that she'll stay together for at least one timed lap on Sunday. We will probably turn down the boost to try to prolong the motor so that Ross can get some practice laps in with the new suspension setup.
We'll let you know if she survives Saturday's practice laps. Keep your fingers cross and wish us luck.

Rules allow other things. For example, Unlimited you can run lexan glass. PTuning had all your standard factory glass. They were the only ones in modified, and then the Greddy Twin Turbo G35 with 608whp, started dual classing as well. The G35 was iin both Modified and Unlimited. The G35 posted times in the 1:05 once they put on the Kuhmo slicks. PTuning had one set of tires, and that was the R888. If they were on the slicks as well, I think they would be chewing at the heals of the G35. The G35 before moving to the Unlimited class also, was running R888's as well, and posting around the same times as PTuning. They were running 15 PSI (500+whp) for this event.
They were forced to turn the boost up, and throw on slicks because of PTuning's 370-380whp Stock motor Scion tC.
.....What they scared for...it's just a Scion right?
Ptuning is the sh*t!!!

Sorry to hear about that ptuning!! How much lower was the compression reading of that cylinder?? That really does suck, and sounds like a good indication to build the other motor asap!

Nice man, thanks for that insider info. I know their dyno read low, so I was posting the numbers as if they were on a dynojet. That is some good info on their dyno none the less though.

Alright, here is some unofficial data for you all. First the car performed VERY well today, but we had some technical problems. After the 3rd session out on track we broke into the 1:38's which is "fast" but i know the car has a 1:36 in it. During my last session the car felt as if it had a flat tire, so I did my best on track to see if it was, and the feeling would come and go. I continued for a lap when it happened, I lost partial steering and all power..... Oh no, I just broke the car... but what did i break? I limped the car back into the pits where it was then pushed to out tent in the paddock.
Without hesitation The gang was on the car like what on rice... like a fat kid on a cupcake... like... well you get the idea! Before I could say much we found out that the hub was broken. The brand new hubs that were custom made for the car, were trashed The passengers side hub actually broke, leaving the caliper as the only thing keeping the wheel on.
As soon as the guys found out calls were being made to scion dealerships. Shawn (who works at a dealership) located all the parts we needed, and we removed everything from the car we needed. Right now the guys are at the shop pressing out the old hubs and bearings, and replacing them.
The car should be up and running for tomorrow, only without the 285's I'm certain with the new sway bar the car will still be a dream to drive, and I'm still shooting for a 1:37.

Dang, that still sounds like good news to me Ross. Sounds like the tC is taking a beating on the tracks, but the reliability for a track car that is, is still pretty good. Do you suspect that the damage to the hub was caused by the 285 wide sticky Toyo's? I'm watching closely as this is good data. And what modifications to the hub if any could possibly be done to accommodate these wide stickies, as I'm sure Toyota probably didn't have in mind that we would be putting massive rubber on this car and pushing these kinds of limits.
