Thread: New setup and build....Updated 5/25/12...723whp!!!!!!

Damn 9500rpm! That's crazy talk! Blasphemy!

At 8800rpm my turbo weezes to put out power. But it allows me to shift when it feels right, instead of clipping the limiter. 1-2nd gears need the extra revs, regardless of power. It just feels right.

I'm sure the new turbo will open things up on the top end a bit, but your setup is just nuts.

Yeah the .96 open housing t4 precision will flow very very well keeping backpressure down alot and allowing it to make power up to 9500 rpms. The sr16 cams will also help in this. Cant wait. Not to mention it is a 67mm billet turbo. B series guys rev their 1.9-2.0L motors to 10500 with this same turbo. It can definitely keep up.

Bigger valves for the VE head? I know they are smaller than the DE valves to improve velocity in the N/A motor.

Im gonna stick with the stock valves for now. I know it has 1mm smaller valves but the port size and flow more than make up for that area. Im not too worried about that for now. I might get a spare head and have some heavy port work and larger valves done to it and do comparisons down the road but for now the stock ve head flows really really well and should perform well.

That's one of the reasons I believe the VE loves low backpressure for big power numbers. The ex side doesn't flow that great, but with a free-flowing turbine housing the motor can respond to big cams on the top end.

Not the case with my tiny 60mm turbine though. Still too small imho. But the response is incredible.

Exactly.

I dont really care about response I just want a nice long fat powerband that if im spinning like crazy in 1st and 2nd and shift too soon before the car catches up with the tires that im not gonna bog down and have to wait for the turbo to spool back up like I had to do with the de head. I still shifted way too early and that was my own fault but was still getting used to the car. However that bogging then blowing the slicks off every single gear cost me a lot of time and a lot of mph. Its basicly like if I had traction and then just seriously granny shifted each gear and coasted for a bit then hit the gas again. Horrible.

I want to extend the powerband to 9500 from the 8800 I was reving the de out to. Plus the slightly higher compression will definitely help with that and yeah the larger turbine housing and better designed billet compressor wheel. All this combined should give me a nice solid powerband from 5500 to 9500. more than enough if I shift a bit to early while spinning to keep me right in the powerband.

Figure I should have no problem hitting full boost by 5500 rpm. I was doing it on the DE with 8.5 to 1 compression. I think this setup will be amazing and really make some serious power. Ill use the AEMs capability to do boost by gear to help with traction a little bit that and suspension and messing with slick pressure.

if you dont mind me asking, whats the bmc manifold gonna run with you suppling the flange? thanks in advance, good luck with the project.
-D

Its running me 900 bucks. A hell of a deal from the 1600 they charge if they have to design and make the flange as before on the b-series they were making the injector ports right into the head flange and the head flange was very thick. So they had to charge more for it. Now they are going with a regular flange and putting the injector bungs on the runner itself where it meets the plenum. So its saving them some money and also lowers the cost of the manifold.

why is it that you share everything with the forum before the wifey...

LMAO
