600+whp on Vitaras, stock sleeved D16!
OK, so I got talked into cranking the boost a bit more on the Vitara's today. We had previously been at 551whp/355tq @ 25psi.
I didn't plan on doing this until later in the summer, but we wanted to have it all tuned out at higher boost levels so that we could just turn it up at the track if we felt we were close to hitting 9's but needed a bit more.
Well, here it is:
609whp/404tq @ 30psi!

Vid of one of the pulls, not sure which one'll be up first.

Streetfire:

This wasn't a 1 pull deal, we made 5 pulls at this boost level, all runs were over 600+whp/400+tq. She's taking it like a soldier!
We had a slight ignition misfire at torque peak on the 2nd pull w/the plugs at .014 gap, so we dropped it to .012 and no more misfires.

Be the first in the 9's with a SOHC street car. 609whp is already an accomplishment on a D16 but doing so with Vitara's makes it a milestone. Your car has persuaded my friend to build a SOHC when none of us could. Big kudos.
No way is that on pump gas.....what turbo? I cant believe that thing is making more power than my b series...time for cams lol. SICK SOHC!!
Awesome man my friend Eric durbin just got done with his build and low and behold it's the exact same set up with differnt turbo and manifold tho. We are actully headed to the dyno now for a tune on 20 psi. Got any advice please email me at legg240sx@yahoo.com if so. Congrats man
Sick numbers though. Thats the highest hp sohc ive heard of.
