All,
I'm slowly piecing together my K24 build and hit a snag trying to select which fuel to run. The car will be driven (not trailered) to the track (30 miles one way) and to local car events (say about 50 miles one way).

Please take a look and share your thoughts. Anything I'm missing? What are you experiences with driving a high HP street car off pump? Just kinda thinking out loud here:

Methanol Injection + 93 Pump:

Pros:

• Inexpensive
• Readily available (VP dealer a few miles from my me)
• Can keep primary injectors small and friendly for street driving.

Cons:

• Can I even make 900whp with this combo?
• Additional complexity of the injection system / tune
• Running out of Meth on the road leaves you SOL for high power pulls.
• Inconsistent fuel quality from the pump

Pump E85

Pros

• Cheapest option
• Great power

Cons

• Closest station to me with E85 is 30 miles/35 mins one way. I'd have to fill jugs and bring them back I guess. How quickly does this get old?
• Fast consumption
• Requires 2000cc+ injectors that will only work well with E85 (meaning, I can't ever run straight pump without it running rough)
• Inconsistent fuel quality from the pump

Race Fuel

Pros

• Great power
• Readily available (VP dealer a few miles from my me)
• Can keep primary injectors small and friendly for street driving.
• Consistent fuel quality

Cons

• Brutally expensive

Any experience with being inconvenienced by not having local E85? Also, just writing this out makes me want to research a dual-injector intake to run 93 and e85.

Bonus question:
Considering 6766 or s369sxe for the turbo setup. Anything else worth considering for the 850whp range with some overhead?

Thanks!

 

>> Pump E85 with a Flex Fuel sensor and run Ignite Red or something similar for race days. You can operate in a range of E70 (assumed) to E98 then and make use of commercially available filling stations. If your flex fuel is setup correctly the tuner will be able to scale your tune and boost from ~E30 to E98.

93+Meth won't get you into the Hp target range safely - and you'd need to be running a direct-port system to flow the quantity required.

 

So 850WHP and driving 50 miles one way and back, what happens if you break? I would just order a drum of e85, when you run out take the drum and fill it up. Also 2000cc injectors run fine on pump gas but the only time I would run pump gas is if the car was going to sit then I would drain the e85 and run pump 91 through the injectors to keep them clean.

 

Thanks for the feedback. I thought about this a lot all week. In the end, race gas is too expensive and methanol is too weak, so I'm stuck with E85. Wish me luck, haha.
