Here's a discussion email from Nigel when I was going to switch from e85 to 110.

"I don't quote power numbers due to the huge variables from dyno to dyno. But, I can tell you E85 will make more power then 110 easily. On larger turbo setup it can potentially allow you to make close to 100 more WHP, or even more on more extreme setups, on E85 compared to 110."

Thats amazing! I thought 100 octane would easily blow away E85...

Do you contribue your high torque numbers in your sig to the E85?

I think the ethanol fuels are the way to go power wise. If q16 made more power than say e98 for example wouldnt you think Nigel would be using it.....

It all comes down to preference.Realtune seems to prefer gas as does DCR, Nigel seems to prefer ethanol.

Are there any race fuels that are unleaded and over 100 octane?

I heard about Shell URT (Unleaded Racing Technology?) about a year ago...I think its rated at about 110Oct and they claim it performs better than c16. But I don't know if any SRTs that have tried it. I was going to test it, but never got a chance to.

Posting on the go with a broken screen...ignore the typos.

^ This. It comes down to price vs power too. Q16 is EXPENSIVE compared to say E98 or race grade E85. Some people like to stick to racing fuel, some like to run ethanol.

Not really. Ive heard of some 110 unleaded but I never see it at pumps.

Thing is. Most e85 users are using pump e85. Which isn't always 85%.

I've heard

Q16
C16
E85


Hands down for the cost is e85.

But thats also oxygenated which most injectors arent rated for.

1st off you cannot compare 100 octane to E85. In general terms e85 = 110 oct.

E85 has an advantage over 110 oct because it seems to allow more aggressive timing advances than 110.

THE BIGGEST ADVANTAGE OF E85 IS THE PRICE!! It's hard to beat $3:50 a gal compared to whatever the price of 110 oct race fuel is now-a-days.

My car picked up 30whp just from switching from 93 octane to E85. NOTHING else was changed.

The biggest disadvantage of water/meth injection is that you need yet another mechanical device to depend on. Also, your mixture needs to stay consistent to get consistent results.

In the end, if price is no issue than run C16!!!

I think e85 is less than 110 oct. at least pump 85. It more around 96 or so.

Could be. I've always read that it's @ 110 oct. But you make a good point about the consistency of E85 and as we both know, the winter blend is completely different than the summer stuff.
