Man we just got the 1.28 housing back on and took her to the street and HOLY F$#%$ spooled really fast 3-4th gear felt like we where spinning all 4 at 54psi. It should be awesome at the track this Sunday

did you drive it on the street? I should have stuck around another few min
You mentioned you're going to go 10:1 compression, why not go higher to 11:1. Its obvious that motor is built really well, and if you're using top notch race fuel, which you are, you should be able to fend off detonation and if you can't, theres always bucket loads of alcohol you could use.
Just some of the STi guys are going that high with compression. Either that or now that you've got the 1.28 housing on there, see if you could squeeze another 500rpm out of the motor with that bump in compression......
Just a thought. Good luck and keep up the good work!
