Building the motor

[engineermike]

... same Chocolate milk engineermike wants to limit us to

Please show me where I said or implied that anyone should not use E85.

What I actually said:

I never said that pump gas will make more power or is safer than E85

Again, I never argued that 93 has the potential to make more power than E85

Is anyone arguing that pump gas is a superior or safer race fuel than E85?

I haven’t stated or implied anywhere that low compression is ideal for E85 or that pump gas is a superior fuel for racing

Please stop being dishonest about what I’ve posted.

I’m not really participating.

18 posts = participation

...you fold and create truths almost at will.

Show me where I posted something incorrect.

When you build your 9.5:1 motor and put the Whipple at 20psi on pump gas then maybe we can truly discuss it.

So my 8.4/1 pushrod motor running 9’s at 146 on pump doesn’t count?

This isn't really a discussion...one side seems to be doing work, the other is slapping the keyboard. Put your money where your mouth is, put away the internet simulators and build yourself a 9.5:1 coyote for you gen 2 or 3 at 15 to 16psi on 93 and then maybe we can speak on an even field. mmmkay?

9.5:1 aluminator is trash lol. No good tuner/shop recommends it, they say stick to 11:1

It’s a cash cow for tuners to sell the same cal over and over again once they have it perfected on a stock motor. Why would a tuner want to spend extra time building you a 9.5/1 cal when he can’t sell it for any more than the one he already has built? I know oem engine calibrators as well as aftermarket tuners and to say the aftermarket knows better is absolute fantasy.

Here’s a fascinating thread where several folks dropped compression of their coyotes and reported results. The very worst result was about in line with what I’ve posted already, With others having much better results. They seem to like their Aluminator SC’s.

You’ve made 12 posts here today, as compared to my 8. I’ve already built a 9 second pump gas car and spent part of today making cal changes and logging knock response in my car. I guess I’m the one working and you’re “slapping the keyboard”.

One side actually attempted to make this a technical discussion while the other seems to think calling gasoline “chocolate milk” all day is a good argument.

Solarflare, Blm is gonna protest your chocolate milk comment... lol

Since he linked that thread. Took 3more psi to match the peak power of stock 11:1. That’s on ethanol fuel. Waiting for the engineer to tell me on 93 and a “couple psi” he would match the output of E85/x boost/11:1. FYI we know coyotes gain anywhere from 60-100hp from pump to e85. So really 3psi extra on 93 and low compression will not match 3 less psi, e85 and 11:1. Disregarding that the e85 car is a much safer setup.

“Solar” and “Flare” sound related to flaming?

 

[SolarFlare]

That supposed to upset anyone? Lmao

This is out of control.

This is out of control.

I agree ,

... But we talking coyote and one side keeps bringing up a Predator motor.

I bring up the predator simply because it’s a valid comparison with a supercharged voodoo, with compression ratio being the biggest difference. Predator seems to win whether on 93 or E85, even though it has a full 2.5 number lower compression ratio.

.... Stop building 10k motors to run Chocolate milk.

Why do you feel the need to tell others what to build or what to fuel it with?

 

[SolarFlare]

Nothing else to say...build it and show us. Would love to see it perform.

Since he linked that thread. Took 3more psi to match the peak power of stock 11:1.

So you dig through a 9 page thread to find the one with the worst outcome, but also the one that responded just as I predicted.

I said dropping 1.5 numbers compression will net a 4.5-7.5% loss. That example lost 5%. I said every psi of boost would get you 20-30 hp back. That example took 3 psi to get 57 hp. Alas, the math checks out!

Now, what you don’t see on the dyno graph in the lower compression, higher boost engine is that the temperature of the compressed mixture charge prior to spark is significantly cooler and the peak pressure after spark is lower, which equates to less chance of detonation, lower part stresses, and ultimately higher reliability.

That’s on ethanol fuel. Waiting for the engineer to tell me on 93 and a “couple psi” he would match the output of E85/x boost/11:1. FYI we know coyotes gain anywhere from 60-100hp from pump to e85. So really 3psi extra on 93 and low compression will not match 3 less psi, e85 and 11:1. Disregarding that the e85 car is a much safer setup.

You STILL seem to think this debate is about E85 vs pump gas.

You seem to gloss over the fact that I already did....with inferior technology. And there’s no way I’m going to skip the design and engineering process just to prove science works to some forum member who calls gasoline chocolate milk.
