Fuel Pump Recommendations For E-85

Changing over to E-85 and all I can see to get is the LPH255 single pump setup with hotwire kit from Racetronix. I have a TA49 mild ported heads, everything else is stock. I'm getting 80 lb injectors and chip combo from TT. My question is...Is there a bigger pump that would be better then the single 255. I'm not looking to run any faster then 11's anyways but I don't want to be cut short on fuel supply because I'm using E-85 and a LPH255 pump. Is the 340 pump not a better choice? Thanks
 
I believe that the Aeromotive 340 has better specs. But you're going to be flowing a lot of fuel and that probably won't be adequate either. I'm not up to speed on the current offerings. Suggest that you call Aeromotive and speak with a tech rep.
 
The DeatschWerks 450 flows more but is bigger than the DeatschWerks 300 ( which is the same size as the 340's) I have not had a chance to see if the 450 will fit in the thirdgen tanks yet but works great in the GN's we build. I will definitely recommend the DeatschWerks 300 over any other pump in the field and should be more than adequate for your goals. Also remember to pick the right size injector for E85, I have seen a lot of people undersize there injector choice.
 
It's always good to see something new. The Deatschwerks 300 flow chart looks a little better than the Aeromotive 340.
 
Wish that I could be of more help, but I'm not an E-85 guy. There is an E-85 Technical Forum on turbobuick.com that will probably be most enlightening. For me, my plan is to use 93 octane gasoline as my main fuel with a supplemental AlkyControl system.

No biggie, I posted there also. If it were a GN I wouldn't have so many questions. Yeah I appreciate all the help though. I love E-85 and we have it all over the place here in Michigan, so its a no brainer. Thanks again
 
Interesting that you're in Michigan. I lived in Michigan for about 30 years. Last year I retrieved the last car that I had stored in Lapeer, MI (1979 Corvette) and swore off ever taking a "special" car to that state ever again. Too many severe potholes, crowned roads, construction bypasses and closed roads. Coincidentally a friend of mine that still lives in SE Michigan told me just last month that they found broken belts in the two front tires on his 1979 Corvette when he took it in for alignment. In that respect, Michigan is a great place to be from!
 
I think that it would be an interesting engineering experiment to explore using E-85 for a short range or drag car. But if possible, I want my street-strip cars to be just as flexible as everyday vehicles. If I want to drive to California for instance, I want maximum range and maximum fuel availability per tankful. These are small gas tanks... With supplemental alcohol, no methanol is used except under high boost conditions. So I could drive coast to coast and not use any. But a car that is so equipped could still be ready for a high boost street challenge anywhere in-between.
 
That's what's nice about E-85.And the in line sensor to since how much ethanol timing is needed..if you don't have it available at the time you just run 93 or what ever else you have to get by...I drive my GN as a daily driver all the time and have had to put gas in it dozens of times..you just have to be smart about boost until you can find another station with E85. I've had a alky pump quit under boost on my low 10 second TType and that cost me around 10k..never again. E85 is hands down the cheapest and best option for high boost applications. And you don't need a front mount..stock is fine. To each his own I always say...and yes..I hate pot holes..lol
 
Sounds good Tony. Since you've tried both, I'll defer to your judgement. On the west side of Michigan, you probably have better roads. But Southeast Michigan is beyond repair!
