Anyone know of a GT500 that has been converted? I know a lot of guys with 03/04 cobras convert and I saw a couple gt500s in the e85 shootout but I cannot find any information about swapping over or anyone mention anything about tuning an e85 gt500. I really want to run on this stuff and I am pretty sure I mostly just need a beefier fuel system/injectors but if anyone has any more information, it would be appreciated. E85 has so much potential.

to do the E85 swap do us GT500 have to worry about any rubber lines an other parts wearing out from running that fuel?

also

with my mods in my sig and adding 80lb FRPP injectors, KB BAP, an CJ MAF get me an easy 700HP on E85 without having to worry about it on the lean side?

thanks guys

I am interested as well, but in a not-so-modified form.

Basically I would just want a tune/pulley/ported blower/throttle body car with an E85 tune for the road course.

On my '03 I had about an 80 whp difference with my E85 tune, plus the huge advantages of combustion cooling.

I am just wondering at around the 600 whp level, if I would need to upgrade the fuel system to run it, or if there would be enough fuel left in it, since the car would be so lightly modified. I guess I could do injectors, and hopefully keep the stock pumps and lines.

I need more info on these cars and E85!!

I'm looking to make the swap as well.
Currently I'm looking to go with 80lb injectors and a BAP just in case.

Current power mods are a 2.59 upper and a FRPP intake (can-tune making 548/556)
I believe it's possible to hit 600/600 with a lower/CJ Throttle body and e85.

Because I live in California and we rarely see lower than 50 degrees in air temp, would I need to change the mixture at all? or could I run 100% e85?

80's might get maxed out with your setup. The BAP will be a must.
I asked a couple of questions on a E85 sight about how fuel required and if I could get to the 750 rwhp level with my current setup. Here are the comments and a ball park minumum fueling requirement that I received.

"If you want to look at ballpark:

Figure 18% driveline loss:
-750 x 1.18 = 885 bhp
-Figure about .75-.80 lb/hp-hr BSFC (brake specific fuel consumption) - say -.775 average
-885hp x .775 lb/hp-hr = 686 lb/hr fuel flow
-Figure 6.5 lb/gallon E85
-686lb/hr / 6.5 lb/gal = 105 gph fuel flow

Or convert to liters:
-105 gal x 3.785 liters/gal = ~400lph

This would be pretty much a bare minimum at what ever fuel pressure you run. Figure any type of voltage drop, pressure rise due to boost, extra fuel so you don't run out and go lean, etc and you'd want some 'safety margin' above that number. Probably looking at something like an aeromotive 1000, bosch 044, etc."

That's the approach I think I'm gonna take as well. Dual 310's with a BAP and bigger injectors should push quite a bit of fuel.
Are you just going to take your stock pumps out and send them off to Paul's?
I was kind of wondering how that process worked?

Which pumps are we talking about when you say 310s? 044s? GSS342s? Im thinking of just using a Fore Hat with 3 GSS342s. I already have the rails. Also 105s are availible but I have yet to see anyone one them.

I'm not sure who actually makes the 310L pumps that Pauls hp installs.

Why would you all want to do this? It is less efficient than regular gas, costs about the same and has been know to cause problems...so why?

You have a lot to learn. Read up on it. Makes more power an burns cleaner than a hybrid.
