The peak torque was 471. The 435 torque was at the end of the power band around 6600rpm's...

Congrats man, those are good numbers.. Hope you're happy and enjoy it! I'm sure you cant wait to be back in the saddle. Sorry you didn't get the high boost setting you wanted but I'm sure you'll get it worked out. Regardless the beast lives again.

Man that sounds so good. It revved up so fast under load. WANT.

My first thought at the end of the video was "Don't call it 571. It's 571.9, it deserves to be rounded off to 572 if you're going to approximate"

I'm glad you're finally getting on the road to success with this project

ANMVQ · 09-05-2014, 07:10 AM

DAMN that was FAST, no like a NA pull that's seems like it last for every LOL, GREAT cant wait to se you driving again!

It feels like I've been reading this thread forever, glad to see it's finally working out for you!

Just wanted to thank everyone again who helped in this ordeal especially Charles at cjm motorsports. You won't find another knowledgeable guy on the vq than him in my opinion. Also bobby at vsr has done exactly what he said he was going to do since this transaction began. With my permission bobby asked if he could one more yourtube video showing the drivability of the car including several roll on's so stay tuned for that. I'm still looking for a nismo front bumper to complete the car along with going with wider tires for more contact patch, hint hint..

Well this engine build came out great. Our tuner paid us a very good compliment saying this engine is quiet and knock sensor is at zero voltage which is dam good for a forged engine.

The power comes on great with the 10:1 CP's

From the video it sounded like the block was bone stock. Yummy... want. But I rather keep a roof over my head at the moment.

Well considering it's a flat response knock sensor it is ALWAYS at 0.02-0.03volts regardless of knock level. (so if you go by knock sensor voltage when tunning it could be pinging every cylinder and you wouldn't know until it was so bad you could hear it)

For some reason the wastegates were opening causing the boost pressure not to go any higher. When I get it back I will tighten up the actuators because before it was hitting 17-19 psi..

You could always spring the actuators as well, go to the hardware store and bick up some various sizes of tension springs and do it up like this

I can't help but to notice on almost every thread you post on it seems so negative.. why .. Try and be positive in life towards things.

His last post was helpful. And he's just a realist.
