holy crap thats amazing for a 2wd! (60 ft time) and congrats on a good run! get some sticks and a turbo and you would be in the 13's if the tranny holds up!!

WOW 9psi,I can only launch at 2psi or it will blow the rear tires off, same size tires with around 28psi,my best 60" is 1.94:thumbsup

yea, I drove around the water, spent a couple seconds warming up the tires, and hit right at 9psi when the last yellow flashed... then at around 25mph, I hit my lock-up switch w/ OD off, hit OD at around 55mph

when I get a bigger turbo, I'm going to run a two-stage boost controller, cuz I hit 35psi damn near right after I launched, and a couple times I lost traction, so I'll have it staged when I go to my 35/40 hybrid... gonna run about 45psi max and 150hp injectors and water injection.....THEN i'll have to figure out how to launch again, lol

30-35psi is what I've heard.... I can ask for sure, They will hit insane boost... definantly not a good idea for more than a moment or so.

35psi is the top of the compressor map for the hx35, I think with a hx40 compressor wheel and housing at least 40psi would be optimal.... wouldn't it? I mean it flows way more air than a hx35
