Just yesterday I spoke with a guy thats already went through 3 motors on E-85. Each time it detonated hard. He's going to C16 and alky for cooling. Car makes 1k to the wheels. PT88, 347 SBF, 26 PSI.
What you have to realize is consistency of the E85. And you dare not start adding pump fuel into the mix as it messes everything up. There is plenty of reading. On most Buicks you cannot drain all the pump fuel out unless you remove the tank and flip it over.
For a mild car with access to E85, you can do either. Just dont get greedy.
Temperature issues with IC is another reason for the alky. Becuase as temps go up.. it will detonate no matter what fuel.
Dont think you cant pop the motor with either. It will happen when greed sets in. Not becuase I sell kits.. my car runs fine on pump gas and alky. Plenty of really high boost spikes.. no issues. Just keep your eye on your tuneup.
Recently I see a trend of moving away from liquid IC's and going back to A-A. using the meth as cooling.

Of course you would push alky kits, (honeslty no pun intended but it is your business so let me stand up for the other end of the spectrum). There are consistant 9 second cars all over the country running E85. To say you just had a guy go through 3 motors soley becuase he was runnning E85 shows that this guy much not be much of a tuner because if he's at a 1000HP levels, he'd better be running a fuel sensor and should have seen a bad mixture way before he blew up 3 motors.
Consistency of E85? How about consistency of Race gas? How about cinsistency of 93? How about consistency of Methanol? How long has the methanol been sitting around and how much water has it collected? There are variables in any fuel we run, no matter what.
Here's why I would never trust my $30K motor on alky alone, extra equipment failures. Think about all of the fail factors in an alky kit (pump, lines, injector, controller, wiring, low methontal level light, methanol consistency, even the plastic tank, etc). There is a whole bunch of extra hardware that could fail. One of those parts fails and your tuned for 30 psi, motor goes BOOM! On E85, you rely on the fuel system, just as you would if you were running 93 or race gas, if you run out of fuel you run out of fuel. Same fail factures with any fuel system
QUOTE RAZOR: Temperature issues with IC is another reason for the alky. Becuase as temps go up.. it will detonate no matter what fuel.
This is the entire point of E85, Ethanol also cools the mixture inside the cylinder, it's doing the same thing with the exception of the alcohol entering through the air as comparing through the fuel. It's entering and mixing inside the cylinder. I had a customers car here that I just converted to E85, I needed to fill the cooling system and decided to do so by simply filling the overflow tank, it took nearly 45 minutes at idle for the car to get hot enough to open the T-stat on E85. It runs that cool.
Now......my side with Razor is......a lot of people have trusted Razors, SMC, etc kits to run high psi and have done it for years with mostly good results aside from a few horror stories here and there. They are tried and true to work! And if you plan to run some BIG HP numbers (600+), your going to need to spend some good money on your fuel system to run E85, but most people with those numbers arent going to soley rely on a double pumper and a hotwire kit anyways.
A good fuel pump, stock lines,120's and hotwire kit will get your car into the 10's on E85.
A good fuel pump, stock lines, 60's, a hotwire kit and an alky kit will get you into the 10's on 93.
You choose which best suits you. If you already have an alky kit, why not use it as extra insurance. I would choose E85 over anything as my primary fuel source on a forced injection car.
