Im happy with its progress, no hic-ups durring the session at all. Im confident it has more room in it on pump... then we'll toss in some 104 and post those results. This is my first 500whp pump-fueled subi done solely on a COBB AP SD.

Great work guys, this car is very impressive! The attention to detail and thought put into this build is top notch, seen this car's build progress in person.

Pretty damn cool!

Thank you!

And no kidding about the FMIC! Here is a picture of the Hawkeye version we are installing today.

God that hood is the ugliest thing I have ever seen, but nice numbers. That 2.7l must be nice for off-boost driving.

The Plastic manifold off the LGT has nice long smooth identical runners, Less heat retention, and ideal fitment for the setup John created with all the custom additions. The LGT version flows as much on the bench as the Metal STI counterpart, so it works well with this build.

Can you post uncorrected numbers with less smoothing? Also 26psi with 11.8 AFR on 92oct is kind of aggressive.

The car looks amazing

Can you get a hold of a nice camera and take a picture of your Turbo inlet / Throttle body area. That looks pretty creative, but kinda grainy.

I also liked the braile batteries located very low. I think that hood is retarded but to each their own.

I was going to ask the same question. Why place 2 batteries at the most front lowest point which is the worst place to re-locate weight unless you are a straight line guy...

Anyways, very nice power band. Seems spools fast for pump gas.

50KG for 2 lightweight batteries? Highly doubtful. They probably total 34 pounds together. That is not going to cause any kind of understeer whatsoever. I also kinda doubt that this car sees a roadcourse to worry about such things.

Probably for DD use. One of those is iffy in cold weather. It seems they had to relocate the battery for the intake pipe. I think it's a bad placement only cause there's plenty of room in the car to do this. Also a fender bender is going to splash battery acid everywhere.

The customers goals for this build was simply;

"I want to daily drive it, I want it to run on pump, I want 500+ to the ground."

Other fuels are simply not available in the Seattle Metro area... Only one station in King County that supplies E85. While there is a station local here to us that supplies 101 at the pump, it also is the only one within reasonable driving distance.

I would love to keep going on 92 as it still has lots of room, and all stock feedback and knock controls are in place. I simply haven't had enough time with cobb sd on this large a turbo.

No thought for weight savings was put into the car. But we wanted to save full use of the trunk (like a good DD should have).

And do you not see the # 15 on each braille battery? Wow 30 pounds + wiring, omg that thing will never be able to turn . As Outback stated, it's a DD and as such it's NEVER going to be at it's limit on the street. I'll guarantee my wife's old Yaris has seen more G's in the corner then this car ever will. And that's ok, not everyone is into that kinda stuff. It's a sick build and I am honestly envious I'll never get to be in the drivers seat of this car. 200tq at 2100rpm is just insane

*beats head on desk*

there is more weight added than just the batteries.

the OP will be going fast. you don't make a 500whp daily driver and drive it to KFC and the kids to soccer practice.

I second this. First thing I did was recheck fuel type. That's really lean. I hope timing is very mild!!!

HTA3586R is 61.4mm compressor with a big hotside...on a 2.7L, 500whp @ 26psi is pretty believable.
