Default 10psi Greddy Turbo

First run was 10psi, untuned. I didn't put the torque on it cause it was having issues with the RPM pickup, so the readings are either spikey or missing a big chunk of the line.

I was running 210whp/186tq.

I am now running 223whp/191tq thanks to some tuning.

Impressive numbers. Are you going to run any more boost?

Well, I am running the Walbro 190HP, so have to swap it out, cause it is maxed. I'll put in a 255HP and replace the wastegate actuator with one that will hold boost. It is dropping boost at 10psi. I should have the water injection kit in when we get all this stuff done, so I'll be shooting for 15-18psi next time around.

Because he needs more fuel supply a this injectors to support more than the 350BHP he's making.

injectors are just a means for fuel to enter the head, nothign to do with the amount of fuel injected. It's all the fuel pump, don't you know anything?

2.5" DP, 3" from the bellhousing back.

It's an ebay IC, don't remember the size, and too lazy to go measure. It works pretty well, which is really surprising.

Must not. The 190HP is maxed, I can't add any more fuel. We tried a 12psi run and it was too lean, so for more boost I need a 255HP. Remember, we are going for 11:1 AF, so maybe the 190 will work if I was running 12:1, or 12.5:1, but I'm not, so it's done.

I don't have the timing map. It's on the tuning laptop. I'm not gonna post it up even if I had it, I don't think that would be fair to my tuner, who has spent alot of time building it.

Basic specs:
Stock Engine
Unorthodox Racing Adj. Cam Gears
JVT Radiator
AEM EMS
Greddy Turbo Kit
2.5" Modified TurboTony DP
3" SS Exhaust
550cc Injectors
Tuner Toys Dual Feed Fuel Rail
AC/PS Removed
Greddy Oil
Motul Diff and Tranny fluid
Greddy Oil Relocation Kit
Oil Cooler
Custom FMIC (Ebay)

Something else is wrong.

I have a 190lph, 550s and I can run more boost on a larger turbo and run richer than 11s.

Your pump is designed to pump even more than mine (at higher psi at least) The pump isn't the problem.

Maybe you need to ditch the AEM for a real EMS?

I run 11psi, 550's and a stock fuel pump and only hit a peak of 70%dc, that's aiming for 11.8:1 AFR

Something else is definitely wrong. The stock fuel pump is capable of supplying enough fuel for 300bhp with the correct sized injectors.

Or maybe the pump isn't working 100%? I got it used, and it has had alot of miles on it, and I am sure the high FPR I was running before I went to the EMS with larger injectors didn't help it any. So like I said before, it's done.

Again, you are assuming the pump is in perfect condition. No matter the reason, the fuel pump is maxed out.
