E85 2010 ZR1 Corvette from LG Motorsports **745 rwhp**
Hey guys,
Wrapping up a 2010 ZR1 here at the shop running on a number of different fuels. I thought you would be interested to see just what a fuel change can make on a car after increasing boost levels on it.
His package includes the following:
Even on 93 octane pump fuel with the modifications we are gaining 95 RWHP and 150 RWTQ!! With a simple fuel and tune download you can add another 100 on both sides to that! So for those of you with access to E85, it shows what it can do to help out a boosted car as long as you have the need for the fuel change and can take full advantage of it.
Video's coming soon.

Very nice! What boost level is that at and was it the same boost for the 93 and E85? Those number E85 numbers are very similar to the Lingenfelter shop car that had similar mods but was running race fuel. I wonder what type of gains you could see on an otherwise stock ZR1 with just an E85 tune (and fuel)?

Wow...... That is impressive 
Sorry for my ignorance but, what happens if you are somewhere needing fuel and E85 is not available ?... will 93 still work or can the tune be modified on the road by a hand held unit?
Or is there a lot more to it?

The boost level was the same. I wasnt happy with the gains on pump gas for such a large investment, and race gas was really out of the question. E85 really answered the need for a quality fuel. I think that there as another 10-20 rwhp on pump gas, but Im a very conservative calibrator.
Were seeing 17 to 18 psi, spinning the blower to max speed, but not over driven.
As for gains on a stock engine, its not worth it without more boost. The stock lower, with any upper, is about the max on pump fuel. When you make the jump to the OD lower, you really need octane, or it suffers.

If Bryan gets caught with out E85, I will have a pump tune he can upload with a laptop. Im working on a hand held calibrator, so he doesn't have to have a laptop.

I am sure many will be looking forward to knowing more about how you would package this... such as price, and can you do this as a kit with a mail order tune for those who live far from you.

93 Octane and all thoses mods, the #'s don't seem all that impressive to be honest. Is there a really a need to swap out the snout, Over drive balancer, ported LS9 blower housing and manifold? Again, not bashing in anyway. Just wondering. Just seems like a lot of mods for the power out put. However, the number on E85 are impressive!

Accessibility to E85 is the key ingredient here. For those living in the corn belt this could be the hot ticket. For others single digit millage calls for careful scrutiny of fuel availability.
IMO a held held tuner would be a must. If you have never driven a car with 750 to the ground you owe it to yourself to try it

I wanted to go the E85 route for the cooler temps and extra octane. I've got no problems with the lower mileage per fuel volume. It's inherent to going E85. Costs wise, it levels out with 93 pump in the end, aside from a slight increase in fuel-ups required to support the extra fuel volume.
Only issue I could see running into is if I travel much outside E85 fuel locations. But unless things change, there are already mandated corn fuel supply increases US-wide, so I don't think this will be a huge problem for many people. Especially if I can switch between E85 and 93 pump when I need to. I'll have to get more specifics on that hand-held. Can't be too hard.

E85 is incredible for boosted cars. So here's my question - What are the negatives, if any? It cost $3.45 in my area right now, and 93 octane is $4.25. So the slight decrease in MPG is offset by the price. That being said, my question is more concerned with driveability issues + engine longevity. It almost seems like a no-brainer to convert every boosted car to E85. Is it that easy, or are their things to be concerned about?

It works equally well (or even better) in motors that are built with ultra compression such as 16:1. Now you talk about a motor that goes "snap crackle pop", nothing sounds like a high compression ethanol fueled motor.

It certainly wasnt impressive, which is why we even brought up the E85 potential. We learn more about these cars every day. What they can handle, what it takes to make power and what makes power.
I feel that 650 rwhp would of been possible on pure 93 pump, but it was stilll a limited power increase, due to the lack of anti-knock capability from 93 pump. This will be an issue with any ZR1 owner as they add boost.
We would run more boost/and or timing if we could keep Intake air temps down, but the heat exchangers are inefficient at this point. We have simply moved them out of their designed range.

- Decreased fuel mileage
- the need for ethanol compatible fuel system parts- not an issue on todays vehicles
- increased tire wear due to increased hp
Ive not done a mileage run yet in Bryans car, but I will soon.
We will probably convert Lou's car to E85, and port the blower and some of the other bits that were done to this car, and see if 800rwhp/900 rwtq is possible out of the stock blower.

Nice.
