Thread: 6262 dyno Results and freeway vid p30

t4 twin scroll 6262? not much would need to be changed. Get the responce of a twin scroll and the flow of a t4.....

new dyno-results from coheed....cool....very interresting input, thanks man !!

but my first conclusion is that the difference between the 16VE, the 20V and the VET cams are generally very small. Both the 20V and VET cams seem to hold the power better past 8000 rpm but the rest is really almost similar.
I am not sure if there is even any advantage for the 20V cams over the VET cams if you combine the VET cams also with a tubular header.

Thats strange because if you compare the specs of both cams the difference is huge !!!

I am now very uncertain if i should do the change to 20V cams.....

you're info is the reason i'm prolly gonna use a twin scroll on my setup when i get this t25 off

BIG thanks for all the info you share

agree , you lucky to be making this decision now as how the new back wheel is out , t4 +twin scrool+bb +new cea turbine+billet= one bad ass mofo , cant wait to see your dyno results with the 20v's and sr16's on that turbo

im gonna order my mazworx rwd manny today , i have to go t3 though but a 6766 t3 .82 will be amazing with this.

All these comparisons are amazing Coheed , this is going to help alot of people when they wanna compare things one day and researching.

Coheed I am not sure what you cam timing settings are because I did not read the complete thread. The 20V cams worked very well when you take out some of the over lap. It gained more mid range and the topend HP did not change.

Mine held up for a while with 30+psi. I ended up JBwelding the cover and never had an issue after it sprung a leak.

he never took the vet cams over 7500rpm. I am sure they would fall flat on their face at 8800

The 20V cams hold a steady powerband. And the driveability difference is noticeable and welcome. The best way I can describe it, is that the 20V cams are made for a 2.0. the 1.6 are made for a 1.6. You can tell a difference.

I will gladly trade off a little bit of torque for some top end. Because that torque has caused me so many problems in the past. Stuff likes to break with big torque. And all that torque with the 6 speed creates a lot of torque steer as well. The 20V cams have a smoother powerband, and they are straight up. I could play with cam timing, but it is very time consuming to tune with them.

I would like to see how a bigger turbo responds as well with these cams. So I may hang onto the 1.6 cams for now. Do some more testing later. The kick the 1.6 cams has is nice, and def lets you know they are kicking. The 20V cams don't kick even close. They feel like the VET cams to me, and they are holding power up top better.

Expect more testing in the future! But for now, lets see what a bigger turbo can do!

Any insight on this is welcome. I was toying with advancing the exhaust side by as much as 5* to see what happens.

These are the cam settings I set up for my friends 2.2L VET back in 02/05/11

Cam settings for 20V cams were
Intake = 0
Exhaust = +5


Well Coheed you are making steps in the right direction. Going with a bigger turbo will only make more HP and the lag will be unnoticable with the VE motor.

Give me a call need to ask a question about your brake setup.
