I guess you don't know the history of the car.
This might help--->

It's also a bridgeport so the curve and the HP/torque figures will ber different than conventional stock/street port setups.

Nice stuff, Chris. Of course E85 works; I don't see why people would say it doesn't.

Very impressive for only 13 psi. I've tempted to switch to E85. I've got 6 stations within 10 miles that carry it, and 45 within 100 miles.

I'm curious what the comfortable boost limit is for rotaries?

... OMG, and with 6 1600 cc injectors you'll need as many stations nearby as possible. I'll bet the gas gauge drops pretty quickly in that sucka on full boost. Not to mention the cloud of unburnt hydrocarbons with the bridgeport, but boy, I bet it sure is FUN. Probably looks like the Concorde on takeoff

Magic question, Zinx.

What were the EGT's like during the low boost runs vs. non-corn fuel?

Thanks Brian!
Just for the record it's a secondary bridgeport.

From what I've been experiencing /noticing with piston motors ignition timing and knock wise I have a very very very good feeling it's going to be very high!
There 's notting a rotary motor loves more than fuel with great cooling effects.

I have not optimise the ignition timing or the AFR's as yet but so far it's a little cooler as to be expected for the type of fuel involved.

Congrats!

Will be interesting to see what happens at ~40 psi

On fuel from the pump cheaper than race fuel!

Very impressive Cris.
I will be keeping a close eye on this thread. I just wish we had more E85 locations in NYC.

Very impressive. I'm looking at making the swap to E85. More power, less cost. Availablity is the only issue why it hasn't become more popular. I have to wait until I move to Grand Praire TX.. (you hear that BDC). There are no stations in Mississippi or Alabama. How would emissions be affected for those of us who wouldn't be able to pass on pump gas. We should be better off right?

ive done a little looking into the emissions thing, and havent found any real hard numbers. seems like nox and co2 drop. thing is they usually dont measure either of those...

I've heard of some piston guys running quite a bit of boost on it. I've personally seen a dsm running 35+ off it.

I think if we are able to run 30 psi off it safely, that would make me seriously think about beefing up my fuel system to handle it. Even if its just 26-28psi, i'd still do it. I could ditch my meth injection too.

Don't ditch it. Both of them together can work wonders.
I know of 4cyl's making over 1000rwhp at 50psi runnig on E-85 and a little methanol injection.

Good point, it would be a pretty limitless combination.

Do you think it will take a stronger ignition system to ignite it for the same boost level?

does it have any effects on AFR ? do I have to add more fuel?

Stoich for E85 is around 9.7, where gas is 14.7. However, your gauge probably reads in lambda and then outputs on a gas scale, so you can use the same afrs. So if you are running E85 and your gauge reads 14.7, it is really 9.7:1. (Experts, correct me if i'm wrong here) More about this: http://en.wikipedia.org/wiki/Stoichiometry

heh, yeah, in the region of 30% more fuel for the same power output.
