I am considering going to E85/Pump98 on my GSR (Haltech Platinum; will have two maps for both fuel types)
However I am a bit confused.
I am hearing mixed opinions of E85 will corrod your fuel pump and fuel lines? Some have said it's fine as long as after 4-5 tanks you fill up with pump98 to flush it out.
Obviously you'd run new lines, rail, surge tank I assume rather than the standard lines with bigger injectors (1000cc)?
Feedback appreciated!.
 
ethanol is a corrosive it will strip the crap and varnish from the inside of your tank and clog your intank pickup filter first then it may possibly eat seals and line depending one what type you run. there alot more to switching to e85 then just a tune and bunging in the fuel if you want to do it properly
 
Aeromotive 340 in-tank fuel pump is the fuel pump I'll be running however will sort out ext. surge tank if I proceed with E85.
 
just set my car up to run e85 havent had the time to get tuned yet though im running 1000cc injectors. im running a big bosch intank pump but have a twin pump surge tank set up ready to go in if i need it. i dont want to run anymore boost than the 21 psi i used to run on pump fuel i really want to try make gains out of the more timing that can go in

Trying to catch me hey tim???
 
It will clean your tankj and lines so you will want to change your filter a couple of times in the first few tanks.
I have been using it in mine on stock lines for a long time now with no problem at all.
I also know a lot of guys in the states that have been running it for years without issues.

I run a 255 walbro in tank with a 044 in the engine bay with 1450cc injectors.
I would probably upgrade your fuel line from the filter in the bay to the rail and back to the reg but i'd leave the stock hard lines to and from the tank.

All this crap about it being super corrosive and eating everything in sight is just that as far as I am concerned. I love the misinformation that gets around the internet! lol
Say it enough and it must be true.

PM me if you want to chat about it some more mate. I can give you some more pointers.
I'll also be out at Willowbank this weekend if you want to come and have a look at it in person.
 
I've been running e85 for 6 months now with no problems &
My fuel system is basically the same as brisvr4
I just replaced the lines from my fuel filter to my bosch 044 and then
To the fuel rail with braided Teflon lines
And I also run 1350 cc injectors and I'm very happy

I've converted "numerous" 4G63's in Adelaide to dual map E85/PULP98 ( with ECMLink where possible) and these have been running for up to 3 years with NO issues. Everything Brisvr4 says I 100% agree with. I use Siemens 910cc injectors. Walbro 255 pumps and 2 initial fuel filter changes and this is good for at least 290kw at the wheels. Cheers Mike
 
I have found nothing corrosive with E85 yet, just change fuel filter/s a few times just in case they get clogged with crap. It is a good fuel, just not economical for daily driving if thats what you are thinking of. So 2 maps would be ideal. Dont really need a surge tank, just another $$ factor. Run in tank pump to external pump to fuel filter to fuel rail and it will be ok. But if you have a surge tank already then why not.
 
Running E85 with: FIC 850cc injectors, Standard fuel lines, Walbro in-tank, Bosch 044 external, Surge Tank
+1 on the bullshit sticks if its said often enough.
 
the only thing you need to remember with E85 is you will need more of it! so your 1000cc injectors are going to be equal to a 670 on normal Pulp

I think thats right isn't it Tim?

67 persent ?

you will need to calculate what power you might make and choose your injectors to suit.
Once again Tim can give you a good idea on that too.


Timmy is my friend .....
 
Engine internals are standard however 280kw-300kw is the aim.

Best of luck with keeping your rod bolts intact, I went from 189kw on 98 pump fuel to 230kw on E85 in my TME without raising boost but gained 25% in torque across the tune.
The gain in torque on the amount of power you are looking for will destroy stock rod bolts.

I am sadly one of these gullible types who believes in the bullshit rumours :lol: and replaced all my stock lines with braided teflon from the tank to the rail, which was far from cheap but being a competition car all bases need to be covered in terms of reliability.
 
Like Scott (marinetowing) I'm also running 230kws with E85 and been using it for almost a year. I have not changed any lines or filters.

If the stock motor breaks, then it breaks. Slowboyracing short block will be ordered.
A couple of other guys in brisbane with EVO 9 and EVO 6's have reached 300kw-330kw on stock bottom end and head bar cams on E85.
 
I wouldn't touch Slowboy at all myself.
Too many horror stories and Mike seems to be more interested in selling realestate now :lol:

Plenty of better shops in Australia that can build you a strong motor.
 
Interesting read, I was gonna go e85/pulp98 also but changed my mind when I kept hearing that I needed to change all the lines etc

Yeah don't touch SBR, too many stories and they take their time on delivery, you might aswell buy a worked short block off eBay.us :p

Rod bolts fail from the forces in tension usually from high rpm. The rod beam itself is normally what fails from an overload of torque but can also break from both forces.
How high were you revving the engine?
 
^^^ Have been told by a lot of reputable people that rod bolts will usually be the first component to fail with the extra torque produced when using E85, especially when pushing over 230kw.

Although this is for a competition car where it spends 95% of it's life sitting close to 7000rpm, no doubt for a street application stresses on the engine are entirely different.
