the 1.06 A/R 35r would be a better bet for 600whp

Yup.. and rev the motor ... 600whp shouldnt be that hard with a good engine and some support mods.

Pistons, head studs, 35R .82, race gas and 100 shot of nitrous.

I just made 505 with this setup without the nitrous.....on a Mustang Dyno. Put it on a Dynojet or Dynapak and that number goes up considerably.

why not gt40r? it's more than capable. if you really want 600 to the ground i would sugguest gt40r its just more practical - look at hydra's website, gt35r+1.06 and fully built heads etc made 590, with a gt40r your built block is the best way to go.

I'd shoot for a qtr mile ET or mph instead of the "600whp." It'll only be 600whp on one dyno, since they all read different. I would definitely get the 1.06 35r if you're looking for that kind of hp. I'd also get some equal length headers, and a small shot of nitrous 50-75, and lots of race gas. You're also gonna need an adequate fuel system, 1000cc injectors and rails, and either dual walbros or an external setup. What kind of tranny and clutch do you plan on using? I think you can get away with a mid/upper 500's with the 2.5, anything higher starts to more challenging.

I hope you have 15k+, cause you're gonna need it. Good luck!

i dunno if id try it on a usdm 2.5. You should look into a crawford 2.65L. It will make getting to your goal so much easier

the car you speak of is my car. A little while later with a few more mods it made678whp.
It made 590whp with the kingpin 35r kit ( 1.06 ) on the stock exhaust manifold. Also this was with 272 non AVCS cams, 1000 cc injectors ( although it took 100% duty cycle to make that power ) no nitrous, Also stock crank. Just make sure you go with big valves, big cams, porting, pistons, and rods.

I found that the 1.06 housing spools slowly so if you want to drag race than you either need to spray it or go with a smaller housing (my best time was a 10.9 @ 138 because I couldn't keep boost between gears). However if you want high power #'s and like to freeway race than this is the housing for you.

I highly doubt that you really need the 40r.

But then again i'm sure someone else will have a different opinion.

Good luck
Alex
