Just curious I have my 2.0 and 6766 combo set at 20 psi almost as a break in stage. I am awaiting fuel and better weather to turn the boost up where it should be. It makes me curious though if anybody had actually dyno'd their big turbos on the low boost setting. (Surely someone has)

62,64,6766, or a 3794 would probably be comparable. Looking for 20-25 psi numbers. It really is irrelevant but the car feels strong even on the pump fuel at that level with very conservative timing.

Again I don't want someone to tell me what my car is making. I want to know what others are doing.

Thank you

 

do a 3rd gear log and post a VD if you want ure thread in this section

FWIW

on a 2.3/ 6765 combo @ 23psi on 93 i made 450

 

Nice. That is similar. Probably much more torque than me but still comparable I would think.

I have not used the VD yet but it is not a bad idea. I will post a pull after work today.

Thank you

 

Aem ems break in tune I did for a member on here... I have to find the graph but it was a buscher cam ff 3794 on 93 oct made 500@19psi.

 

The DSport Cam test was done at 21psi on an HTA 86 and topped out around 600whp. Those turbos could make even more possibly.

 

First pull on the Dyno during tuning was 20psi and it made 460 I think. 6766 bb

Thats got mine in it.

 

On a conservative tune on a 2.L I was 496 at 19psi. 19psi, 92 octane, 11* at 8k.

 

I made on 14.5 psi 459whp and 23-24psi 601whp all those number was done on 91oct . My car has 2.1L and 6766 t4

 

548hp on a mustang dyno in Denver (mile high altitude) on 6765 91oct

 

739whp @ 29psi 3794 2.4LR by TTP on Dynojet 424x

 

Seems like the turbos are out of there range when ran in the lower boost maps or curves similar sized turbos should be used

 

That was my experience. I was down power on the 3794 compared to the 3586 at 26psi...like 50whp.

 

It depends on the displacement and engine configuration when making that determination.

 

2.4LR, built head, 92 octane.
- 6262, 511whp at 23psi, 12* at 7500
- 6466, 554whp at 26psi, 10* at 7500
