My xa on our dyno makes 86whp stock, 286..... 200whp gain. Never kept tally on cost, I built the motor,exhaust, turbo kit myself so that is a lot of money not spent.

 

revival here, but damn this project is amazing. did you ever tune it on race gas? and btw i forgot to ask in my pm, what suspension set up are you running?

 

I never tuned it on race gas, because im a bit afraid that my factory 8mm headbolts will stretch... haha. Truthfully, I cannot imagine my car any faster... it is hard enough to keep strait as it is. It burns tires at highway speeds and beyond that you have to grip steering wheel tight in 4th and 5th gear as it can yank out of your hand from torque steer.

If someone runs faster than 12.6, I will throw it back on the dyno.

For suspension I run Progress coilovers, but with 450lb springs in front instead of 200lb. No front sway bar, and Progress rear sway bar.

 

e85 tune shortly, but it is more of a test. We will be tuning on wastegate pressure (17psi) because I don't have injectors to support 27psi on e85. Ill post comparison between pump gas with wmi on 17psi and e85 at 17psi.
If there is a significant gain I will get 900cc injectors and shoot for 320whp or more... which will certainly put me into the 11's at over 120mph in the 1/4.

Oh! Next month marks 2 years this motor has been in my car, considering I have beat on it and drive everyday that makes me happy.
