Default Tires!

My guess is their tire size couldn't handle even more power, and TORQUE?

Agreed. And with the arrival of the Nissan Leaf and the Chevy Volt, my least favorite car magazine MOTOR TREND finally has an accurate title.

Just hope that the real reason isn't a lack of headroom in the fuel system.

I'm so glad people feel comfortable with converting to E85. I on the other hand prefer to follow the fuel that the manufacturer recommends.

18 months usage is not long term usage. I hope you are correct yet I would personally not go against the fuel requirements of the manufacturer for a vehicle.

Have fun!

I would rather GM have offered directly from the factory... the owners of the LT1 the flex fuel capability

Tree huggers don't care, don't listen and hang their hat on global warming. Huge fail. Plus using more oil all around to refine and to run. JUNK!

Believe you me, the only reason they didn't is because it would be faster than a Z06... made me pretty upset how he made it such a selling factor in the video that the truck gains 30hp, and 50tq... but when it comes to the corvette, it was almost a laughing matter. BS

How does it have more corrosion???

Yes gas mileage is less. But it's a vette. A 50k + vette, if your worried about gas go get a volt.

I've been running e85 in cars for the last 5-6 years. And do 3-4 e85 conversions a month for customers.

From a boost aspect. It is a HUGE gain over pump gas. At WOT you use around 30% more fuel ( depending on compression) but that mean more fuel in the combustion chamber every time it pops. More fuel = less heat = less detonation = push it harder = more hp and tq

Correct! It's an internal combustion engine, not an electric motor. At least not yet!

Default Heck!

If the Z51 was too cool why would anyone buy the Z06? 90% of the people buying the base Vette don't even know the difference! There is a multitude of potential reasons!
But, for me my paid for 02 Z06 turbo lowered with T1 sway bars, and track tires is still looking really good! Stick and All! Thanks GM!

So your unbiased opinion is that GM is only changing the PCM tune and there is no rubber fuel lines hardware etc changes when GM converts a vehicle for E85?

Thank you for your insights.

Nobody uses rubber fuel lines anymore.

Pull up the fuel system for a flex fuel car and the same car not flex fuel. Biggest difference is the flex fuel sensor.

But let me ask this. If it will take e10. Why wouldn't it take e85 in the same system????

I don't mean pumps and **** like that. I Just mean the system, the rubber houses as you call it. If e85 will eat the hose do will e10. Ethanol is ethanol. Sure the e10 MIGHT( and I mean a big MIGHT) take longer. But NO auto company will put something in a car that ethanol can "eat" away. Why...... Because all cars after like 1995 have to be able to run on ethanol e10. And fuel is a touchy situation. So auto companies have to look at 20-30-50 years from now. Will they get sued because a piece they put on failed....??? Or will they spend the faction of a penny more and use the stuff required by law???

I'm not certain what "head room" means in this context, but if it means what I think it means, I suspect this may be the case.

Specifically: The high-pressure DI pump probably doesn't have the mass flow throughput capacity to support E85, the mass flow (as pounds / hp-hr) of which is more than that of gasoline because of the different stoichiometry. This is of course why the miles / gallon is less, even though the miles / fuel Btu (i.e., engine efficiency) is usually slightly more.

If you read the blurbs and watch the videos, it's clear that GM struggled with the LT1 DI pump. As I recall, in one video, someone hints that flow capacity was an issue. If this is the case, aftermarket conversion to E85 may not be straightforward, especially if WOT peak power is an objective.

I still don't understand why people wanted E85 in the first place... I've asked this several times and never gotten a good answer.

Because it makes more power and torque because it runs cooler (which means you can run far more timing and compression).

Read any of the big E85 threads and they'll catch you up.

Please don't ask me questions about the conversion parts required to go E85 fuel long term on a corvette. I have NOT got the slightest idea what is. Required.

My concern is supposedly there are parts needed and without anything more than a tune I would have a concern.....

I'm not saying the retune can't cut it....I'm just suggesting that changing just some parts might not cut it long term.... That GM may in their ultimate wisdom from long term research alter various parts beyond what some "tuners" see fit.... My concern is real world longer term fuel sYstem failure. I take that more seriously than a cam or header failure etc...

You may be correct. I would think specific confirmation on various fUel sYstem parts would be prudent.

E85 designed for the corvette directly from GM would have been much better.

Hence why I asked mr Lee the question on auto line after hours show.


Just my opinion and good luck to you.

You asked??? That's you on the show??? That's pretty cool.

I agree auto companies do ALOT more research then tuners and shops like myself. I will say out if the big 3. Chrysler is the only one I have ran across that wasn't spot on perfect.

But like c6z cars for example. New injectors and a tune and it will runs great on e85.

Honestly I will let everyone knows how e85 and the new LT1 goes together. I plan to convert. And plan to boost it as quickly as I can.
