This car is our new test mule, which is replacing the old test mule, Elvis. The one main difference between the two being this one you can drive legally on the road. We recently completed a few NASA Time Trial Sessions at Miller Motor Speedway and Buttonwillow, taking home 2 first places, 1 3rd place and fastest track time of the weekend. The next event we will be held July 8-9, at Willow Springs International Raceway. Anyone is more than welcome to drop by and say hi or possibly get a ride in our shop car. Also anyone is more than welcome to drop by the shop to get a free ride in the new Elvis.

Awesome! I am interested in how long the stock block will last given that it has 430whp and is run hard at the track. Have you guys raised the rev limiter on this car at all?

We have raised the rev limiter to 7900 for right now. We are in the process of testing the limitations of the stock block. Just like you said we want to know how reliable a stock block can really be for hard track racing.

AWESOME!! I wish more people would do things like this, that way we can figure out the limitations of the stock sti block. Please keep us updated in this thread on how the car is holding up, i'm very interested in this.

I have a 400whp stocker with a 7.5K rev limiter so i'm not that far off, i drive my car pretty easy so it'll be interesting to see how a similar setup holds together when it is pushed hard. Good job Crawford and keep the good info comming!

So how is this driving legally with upgraded turbo, FMIC, TBE etc? Not bashing, just curious. Drive that thing past one of the new CHP Smog checks and you will find out quickly how legal it is!

Nice work regardless of how legal it is.

Turbo kit looks to put out some great power. Looks a little laggy on the bottom though. Care to share the TQ numbers?

For Big willow the turbo should be ok ecpt for turn 3..... it will make up for it thru 7 and 8 and out of 9 to turn 1.... with the heat and if we can keep tires on the car we might break into the 1:29's..... the car did low 1:29's with a smaller turbo and less HP last year..... we will see how 100 + degrees and more HP and torque will do... If we are lucky NASA will let the morning session count..... if not session 2 will be the only good one on the track as it will be really hot.....

There will be a couple of real fast Evo's out there for the weekend so I hope we can get the job done!!!! If we are lucky we will have the ball joint extenders on the car!!!! Tom if you are out there all I need is to have them by the July 6th.....

If anyone has a chance then come on out as ESPN 2 is supposed to be out filming for a Tuner episode to air soon...... The more STI's and WRX's the better!!!!! Lets have more Subies out there than EVO's.....

LOVERS and HATERS are welcome...... Lets have a good show for the TV crew!!!!!

See Ya at the track....

Being as it's a stock STI short-block, the dreaded bobble-head syndrome shouldn't be a problem. You guys crack me up.

Then please come by and see for yourself. The car is here every day that it's not at the track, and we have nothing to hide except for our tuning.

unless you guys start giving out Quirt bobblehead dolls to visitors, that would be worth the drive.

I was running 21-22 psi on 91 octane with STi pink injectors (565's i believe) on my 2.2L WRX with stock heads and i never had any problems. It was 350 whp on the ESX dyno, which is about 500 whp on the crawford dyno

Not really. I had to go to the State Smog Referee. turbo, exhaust, fmic, nos, etc all back to stock. It still passed with the 2.2L stroker though.

I'm running 22psi on basically 91oct putting down ~400whp with a 7.5K rpm redline, so i don't see what the big deal is, it's definatelt possible. You guys need to grow up

EDIT: All you guys saying "ahhh, it doesn't match up" only have a DP, that's why you don't know what you are talking about. Keep your mouth shut unless you actually know what the hell you are talking about.

How big are USDM STi injectors?

And just looking at the 433 whp can be misleading. The stocker on there is at 250 whp. So this would be back around 400 whp on another dyno that does stockers at 210-220 whp.
