880's would work on standard 93 for sure .... and you would need the dual map switch to go back and forth between 93 and ethanol, which I know Evolution Motorsports offers, don't know about other companies ...

 

Yes, 880s work on 93, that is my current setup which runs very well. I have the map switch as well. This apparently is not going to be quick or easy as I had hoped. Injectors of the size being tossed around on this thread necessary to make 900whp on E85 are going to have some bad manners on start-up, idle, and driveability I would imagine. I am not going to give up the car's current streetability. I am looking forward to more input from the experts on this subject. Hopefully more will chime in on Monday after the holiday weekend.
Does anyone know the current high power mark on E85 in a 996TT?

 

Sure will be need to change injectors to pump gas, E85 needs little less fuel but to 900whp at least 1200cc injectors will be needed.

 

Kev,
I know this has been touched on in this thread earlier, but the cold start issue could be a deal breaker for me. A friend of mine has a Mitsu Evo X that has been heavily modded and runs on E85. I have been to the track with him a lot and it ALWAYS takes about 30-45 min to get that thing going in the mornings. His tuner has looked at it several times with no real fix.
Knowing you, if you had to deal with this even a couple of times, it would drive you nuts.
Not sure if this is an issue that has come up with other Porsches that have been converted, but it seems like it's not as easy as changing injectors and a tune as previously discussed. There are E85 pumps all over the place around here as well so I can see where it would be convenient, but not at the cost of reliability/driveability, IMHO.

 

Evo's are hard on cold start on E100 , but it should not on E85. JUst did a 996 on E100 with 1680 injectors and cranks eazy!

 

That may be the case in you neck of the woods but here we have 100 degree heat to zero and with clean roads I like to drive at any temp. The cold start needs to be spot on here. One more problem is we want it all. 10 years ago a 500 wheel hp car was thought to be border line race car not a street car. Look where we are at now!

 

louis , 30-45 min ?or seconds ?my evo is tuned to e85 and yeah it is a bit of a b1tch in the am ,after a few min shes good to go.but no where near 30 to 45.

 

Minutes, after it gets going it starts up all day just fine. It just does not seem to get enough fuel at first.

 

Luis, I agree on the cold start issue, a total dealbreaker if that is how it performs. Just not sure if there is enough data on the E85 996TT at the power levels I am looking for to make a general statement. The convenience of that fuel on every corner is just too appealing. Even if the car only made 800 that would be fine, as long as it is 800 all day,every day. I guess I will do my research and see what direction it will take me. Thanks

 

Leave it alone.Buy a Ford Gt or a Lambo!:-)

 

Kevin,
what cold start will be an issue ,maybe a bit more or a bit less , but it will be there.

another thing to think about is do you really drive the car all the much in the winter anyway?

once she warms up ,25 min or so she will good to go.oh also your car will smell liek vodka lol my evo stinks like pure grain alc.

 

Kevin,

First of all greeting from the great white north

I love the idea of E85 but you have such a unique set-up it is way
over my head what your conversion would require. After become a race gas junky with my previous car (Thanks to getting "Slossed" by S-351),
I became very tired of transporting, storing, pumping, planning for long
drives and taking extra with me etc, RACE GAS. What a PITA !!

We are in the land of Corn here, like it or not, make sense or not, it is
plentiful. So my next car will be E85 baby.

Our buddy KA had a SuperCharged Viper that he converted to E85 and it
made significantly more power on Corn which was a nice bonus.

Today E85 is $ 2.30 to $ 2.49 in Minnesota

 

Luis,

This is not a problem at all, I have a cold start kit that either works thru temperature sensor or pulse button from the cabin. This kit injects regular 93 octane for cold starts, fixing that problem once for all, let me know if you need help with that.

 

You don't have to worry about power, it has been proven over and over that ethanol makes more power that even Q or C16 period ....

Let me know if you need help with the cold start, as I can ship the kit directly to you, or provide the parts that you need, I usually get them from Brazil, as they are parts available on 90% of the factory cars.

 

Kevin - I will be fighting this issue this week on the lambo build. I agree 100% - if you lose the start up manners and driveability what is the point. If it was a race car or a occasional driver - maybe. But if you plan to drive it like I do it has to behave properly. - Eric
