Just want to say thanks to all,
cars running on e85 (blow through carb) and by the seat of your pants dyno is making more power on 7 pounds than it was on 15 pounds running 98 but it does have a lot more timing in it
,The engine is running much cooler and even driving around the block on and off boost ,when inspecting the plug you can easly hold them in your hand,well worth the effort.

Cheers guys,Im using M2 upper cylinder lubricant its made by VP racing fuels,it has stabilizers in it to counteract and buffer the change in p alkalintiy that occurs in E85 when it takes on moisture,also help protect rubbers....But yes will keep my eye on things...
cheers anthony

You can check the Cole Palmer materials database to check compatibility with ethanol and toluene (close enough to petrol). Generally ethanol is one of the more gentle chemicals. It's fine with most rubbers. It is hygroscopic (means it sucks water out of the air), pretty much just means its best not to leave it too long. I doubt you'll have any problems. Best approach is just run with it and keep an eye on things. Upgrade if you have problems.

Yeah he's a busy man but always happy to help he tuned my Z18 on E85

typing "e85 AFR" into google will give you all the information you need...

cheers L18_B110 i will do i have a great table my mate gave me changes 98/e85/alch to lambda and a/f ratio
trb012 I was going too,but didn't want to bug the chap as im sure he answers quite a few... :)
Thanks for the speedy responses cheers

Don't be surprised if your pumps eventually fail.theres a reason they make specific e85 fuel pumps and line.but if you want to keep costs down them try your luck

Ethanol is not corrosive like methanol is, so don't worry about it "eating everything away".

Get in contact with Simon (sikyne) on here he has a heap of experience tuning E85 especially on turbo a series engines.

No i wasn't changing anything I was going to run the E85 and rubber lubricant
its working fine with mmy friends E85 set up and yes i have asked him about E85 safe ratio, he said E85 has a rich power number and lean one BUT his numbers are different due to forged pistons,large cams (changes in dynamic pressure) ect So that why i was asking here thought there mimght have been a few in the same boat std motors,boost and E85
most tune the A/f on 98 a little fat at 12-12.5 so im going to Aim for .82 on E85 which is roughly around 12 on the petrol scale see what happens
Cheers for your help guys

I hope your also redoing your whole fuel system mate.lines,pump,filters etc otherwise the ethonal will just eat away at everything
