I have nearly identical fuel system but I’m using Ethanol fuel. Most of the time it’s registering around E-80.

I only come to this forum to check this very thread to see what this kit does on pump gas. I thought by now this thing would be over flowing with people's results.

Been driving mine and fine tuning things since September last year. Going on dyno for some pulls next Saturday.

Where you headed for that? There’s not many VQ tuning shops in DFW unfortunately.

Any word on CA legality?

Are you planning to submit for CARB exemption?

A guy in Celina that has a shop. He focuses on Subaru but wrenches on pretty much anything and does general mechanic work. Not expecting any tuning from him just use of dyno for pulls. Ivan’s Performance Shop.

TopgunZ - any plans to make available a recirculating BPV kit similar to what Soho did for those who either don't like the BOV noise or just like to fly under the radar?

Here you go. This happened a couple days ago. 93 pump...600whp/500wtq just touching 16psi.

They did that because that design makes the notorious "flutter" or choppy bov That is inherent to all vortech air to air kits.

There might be some customers that just want a quieter car also I guess.

It would be extremely easy to do on these. Just weld a 1.5" long , 1.5" long pipe on the side of the intake and run a 1.5" heater hose to it from the bov. However, you would want to run that wastegated option also or reduce your pulley size to run say 16psi.

His FB post said ID1300’s

Does anyone care to guess how high I can go (in terms of whp) with just 1050cc injectors as that's what my tuner has included in my setup (installation expected to begin in a week or so). The aim is around 525 whp for me. Fingers crossed that 1050cc will do the trick.

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?
