The turbo is def capable of MORE then 400whp as weve already seen. On e85 it should be able to do it with just the stock stuff I think and an external gate


After a little more research, it looks like you are exactly right. My mistake. But this isnt a race car though. And would be on lower boost settings a majority of the time. To this point, would it really matter?


Na your right. Doesnt really matter. It just may make it harder to control the boost at higher boost levels. Prob wont be much of an Issue though. Your on a good path! Not to many people know the tq that your making even with much bigger turbos!

Thanks buddy! I gotta give credit where it is due, @crznx2000 did most of the work. We are getting it there. Looking for 400hp.

Is that with E85? I require 30% more fuel flow.

I would go through and check over the fuel setup. Upgrading the pump would be good along with the relay how Gio said. We had cars pick up great power doing so but also needed to adjust the fuel again due to a solid fuel delivery.

Also, what kind of plug wires do you have? My buddy Jasons ve-t did the same up top when his car was being tuned. We threw on my brand new oem plug wires and it was smooth for the rest of the night.

3 bar setup?

45psi with the vacuum on. Unless you modify the walbro relief valve I would look that the total fuel pressure under full boost does not go over 70psi of fuel pressure. The pump will not maintain it for long periods.
I use the deautch works 320 pump with a relay. Just over 503whp on their side feed 1000cc injectors at 20psi of boost,fuel pressure base was at 41with the vacuum on.

On my car it was at 3 bar. Those injectors came of my buddies car that was just over 503whp and had some more fuel still left, but he was running a bigger pump a 320 from deautsch works(requires a separate relay)

The bigger the better on wastegate especially when location is not prioritise.
