if so what sort of revs are you seeing full boost, what boost are you running, what power are you making, what cams crank and fuel are you running,

i am building a 2.2l with 280 cams, e85 35psi, i think this turbo shouldnt be to big?

 

Im running a 10:1 LR 2.0 with the 3794. Still waiting on the tune, but expect it to hit full boost (40psi), around 6k rpm. Stock crank, kelford 280's, c-16, and should be at around 800 on the mustang.

Should be fine with your setup, should see full boost a few hundred rpm sooner than I.

 

Jms is running one and one of the guys from English racing is running one on a 2.4 and Awd did the testing on them before they were sold so there should be a few dyno charts floating around if I ever upgrade my hta86 that's what I am going with .

 

I have one on my car right now. Earlier this year it was a single scroll T3 with the 0.82 A/r turbine housing and I am switching to a 1.15 A/r T4 twin scroll for next year.

And how laggy is it, how does it drive?

On a MIVEC 2.4 even the single scroll is very responsive for it size. It doesnt match the 3586 power per pound until over 30psi, but in my combo it didnt lose spool on the street. 21psi at 4200.

Here is the dyno plot, logs, and video of pulls-

I presume it will be some time before I test the twin scroll in anything close to back to back to this however.

 

Thats completely insane. Cheers for the info

 

That's incredible.

 

Awesome what size Wastegate have you got to control boost?

 

Thats the part that know one believes. A single 38mm F38 Tial with a 0.9bar spring and it only creeps about 4 lbs on pumpgas at low boost. Next year it will be 2 38s with 1.3 bar as I am switching to twin scroll with this turbo.

 

Thats pretty interesting! Look forward to seeing how changing to twin scroll affects it

 

I am surprised I had boost creep on my uppart turbo with the 38mm I changed to 44mm with 19psi spring that sorted it but don't want to have problems again. Why are you adding second gate? I would have thought changing to a bigger housing would help reduce Wastegate creep?

 

I am going from single scroll to twin scroll so its because of that.

John do you ming me asking what cams you are running and what lobe seperation? benj interested as to what your lobe seperation is set to as well?
also have any of you guys measured turbine inlet pressure with the 3794? i am wondering how the small t3 houing performs when the boost starts getting up there?
