What fuel pump?

I notice the invoice mentioning "CJ Motorsports S1.E Fuel system" but that in itself doesn't really tell which pump is included in my setup, I guess. I better ask the shop/tuner...

I'm suppose something like a Walbro 400 is needed in combination with the 1050cc in order to reach 525 whp?

The S1.E is the return fuel system set up. A good pump to use would be the Walbro 450. I got into the 600's with 1050's and a single Walbro 450. For your needs, that combo would be perfect

Been running my kit since last August, id1050 injectors, aeromotive 340, currently on 91 about 11psi. Going to be upgrading the clutch soon, I have the CJM s1.e and flex fuel ready to go in. Plan to turn up the boost to 14-15psi.

I have had no real issues with the kit, it's great. Other than a slight flutter here and there. If anyone has any questions on the install feel free hmu.

I havent dyno'd it yet. If I have to guess from the butt dyno, probably between 400-450.

You might start running out of pump going any higher boost.

The G37 intake was addressed a long time ago. Its easily accomplished by not using pins. You just need a different coupler that comes off the inlet of the SC. I have been sending that setup out since the first feedback of that hood latch issue.

What! I have not seen this, I thought the G's were stuck needing hood pins!

Pics?

If we do it’s all good. Now that we are installing the cjm fuel system that has the inline fuel filter we can install the walbro 450. Not worried about cutting out the one in the fuel basket.
