where did the thread go for the twinscroll 4088 kit for the Evo 8/9? I was trying to watch that thread pretty close to see how the spool was as well as power figures. anyone have any info on one of these kits installed and tuned???

I have about 100 + maybe a few miles till I can turn the boost way up on mine.

I did put down 485 hp on 22lbs 460 TQ

Spooling at 4200 I think it was on a 2.3

 

What cams, intake manifold and compression are you running? Those are the other 3 big items that tend to make a huge difference in spool and power. Thanks for your response!

 

Kelford 280's
Stock IM cause AMS is dragging their feet with the F1
9:1 I beleive in compression

As far as I know you can't have a high compression pistons like 10:1 and also have a stroker which will push the compression up higher. But I could be wrong with this assumption.

 

what rpm do you see 20psi by? also, which dyno in colorado did you use?

 

I used the at carz which is a Superflow.

I will have to look at my dyno's cause I forget what I got at 20 psi. At work now.

 

Good info. I'll be running the Kelford 280/272 setup on my 9. Built 2.0, 8.5:1 compression and 99% sure on the stock intake manifold ported with 68mm throttle body!

I would like to see where you hit 20psi as well. Thanks again for the remarks.

 

I tried watching today as I shifted and it looks around 3800-4100 around 20 psi. I was not laying into it hard but had some fun.

 

Brandon -

We need to get you going on this! =)

 

Agreed. The motor is coming together pretty well. The biggest item left to buy short of the turbo kit is the clutch to handle it. Plus I need to pick up an UICP from you guys as well!
