Thread: VE-T twin scroll setup

Manifold is getting done in about two weeks. The time is soon!

Really wish I could change my vote.

I'd say you'd make at least 550whp at over 20psi. I'm a believer now that I've actually seen my own numbers. You should EASILY put down more than me, especially with a divided housing setup.

Today's dyno results.



It was just a little bit less than last year, but I added some extra fuel in there. I will post the new manifold chart as soon as I get it done. This is 15psi also.

That manifold is KILLING you.

This dynos are with the cocurrent log Coheed? did you try adding more timing?

yes, stock JWT map. I don't wanna play with timing too much. I could make more power, I just want it safe.

What cams settings did you tried?

^^^ None haha. These are complete drop in results for the cams. Cam timing could yield amazing results with some sr16 cams, but the VET cams are pretty decently optimized. I am not sure I will see the power gains I am looking for with these lower duration cams, so I will be testing the stock cams down the road as well. I also wanna hear the VVL pop, which is a sound you cannot hear with just the intake switching on the vet cams. These cams coupled with a nice high rpm powerband will make this powerband incredibly stout.

When the VET cams switch, the motor just gets a louder intake growl, but it isn't pronounced like the stock cams are. I don't think these cams are really going to hold it back much on my setup, and they spool the turbo really quick. I have thought about trying some 20v cams to see how they like turbo. This will have to wait until the next build though.

This motor did very well considering the miles, abuse, and state of tune. I wasn't really expecting more than 340whp since I detuned it.

I should add that by looking at my old graph that I am making power a lot sooner, but power is not quite as high. On these cams, there seems to be another jump in torque at 7200rpm which I missed by not revving quite high enough to see. I prob would have made the same power as last year, even though the AFRs are getting richer on the top end. I really need to get this wastegate from creeping open though, because it is killing spool time.

Time for an electronic boost controller.

PS, the poll is for high boost 22-24psi. This dyno was on 15psi holding rock solid all the way to redline. A manual boost controller will go on when the new manifold is done so we can really see what she will do. This turbo likes higher boost levels to really perform, which is nice cause I may not make as much power as others on low boost. I will just have more room to really push it. I can do 30psi of boost and still operate very efficiently on the compressor map.

The pic I posted earlier got deleted, but it is pretty sick so I will post it up again. Let me know what you guys think eh?
