I have a return style system. These are the hellcat pumps. I talked to Walbro and the only difference between these and the 465's is the 470s flow 20% more. I figured out the issue. I deleted my stock FRPS and need to hook that back up so I can adjust the tune.
The only thing I did was change out from the F90000274 pumps to the F90000285. I disconnected one pump to see if it would idle and it almost dies. Plus my car is tuned without reading fuel pressure. It was bypassed because I don't have the stock FRPS. I use my AEM guage to read fuel pressure...
Im going to be between 900 to 1000hp. So I changed my fuel hat that had the 450hp because it was leaking at the top. Got a new Fore Hat with the 470s, kept base pressure the same, 40psi and my AFRs are 17 to 18 at Idle. Turned it up to 50psi and it drops down to 14 but then back up again to 17.
Just toying with the idea of trading my 3.4 whipple crusher setup for a turbo one. Wondering if there is anybody who is currently turbo'd and would like to go supercharged. My 3.4 crusher is practically brand new. It was on the car for the dyno and a saturday night.
Im selling a new SCT ba5000 that I bought for my crusher setup. My tuner decided to use a stock maf because it reads better in the crusher intake tube. I paid 275 for the maf. Im asking $200 shipped.
Im selling a new sct ba5000 maf. I bought to go in my 3.4 crusher but my tuner used a stock maf sensor because of the size of the intake tube is too big for the ba5000 to work properly. So i wouldnt put this in a crusher setup. I paid $275 but im asking $200 shipped.
