Fueling upgrade needs for E85 Whipple?

[Kona 18]

Wish some one would come with a kit to convert the GT 350’s stock dual pump to a return system .

You can, assuming you are referring to converting a actual GT350's stock fuel system into return style. all you really need are the hoses, the regulator, and a bulkhead to work as a return port on your stock hat.

Yes , I am looking at options to run E85 on my GT 350(could do dual BAPS) or one these dual pump OEM return systems but I already have the dual pumps on my car .

I don’t have the mechanical know how so would be willing to pay for a turn key kit . I doubt there is much of market for such a kit though .

You should't need anything to hit 800WHP. I have the stage 2 kit, Gen 3 unit, longtubes, 3.6 pulley and 94 fuel and I'm at 803whp. No fuel upgrades other then what came with the whipple kit. I have a 17 not a 18 but the 18 should be even easier again. Tuner says that I still have a little bit of room on the fuel system and that It's not maxed out. Car is tuned and running safely.

How much timing with the 94 octane ?
My 18 just made 808 SAE on that pulley/E85 but through the stock exhaust/cats with 22* . There is probably another 25-30 whp to be had If added long tubes/deleted the cars but I want to avoid all that loud raspy noise if I can . Lol

I pulled the car to 8000rpm. At 7500 to 8000 the timing goes from 18* to 19.5*. I usually never change gear over 7500 so I'll mostly see around 17.5- 18* timing max.

And yes It's sooo loud. I have roush mufflers with the longtubes and no cats. I am connsidering adding the borla mid resonater

Thanks man but 93 octane and 775-800 will more than likely not happen. It may with a can of octanium or some other octane booster but plain 93...... I wouldn’t chance it. An you get E85 in your area? What fuel system do you have? That’d be much safer to reach your goal. BTW, I have the regular heat exchanger too and not the big oversized one.

Very nice and impressive with 94
On the 18’s whipple says 1* is worth about 25 hp so if you ran race gas /E85 with 22* you would probably pick up at least another 60 rwhp

On mine operator let off at 7400 but power was still climbing so it may have an extra 20-30 if I pull to 8000 rpm .
