Last time I checked it was like 13.00 a gallon. That was begining of summer. Sorry if my prices weren't current.
Fuel pump, injectors, fuel pressure regulator, a way to add fuel to you're map. Or you could just do what sid does and litereally dial up the fuel pressure and tune that way.
I'm also thinking that could become a trend too. Its what the evo guys are doing. Thats the link I posted. Those are all stock cars or close to stock cars running stock turbos. Those gains are just over what the car was already making. Which is pretty nuts. Typically they are seeing a gain of 40-50hp and 75lb-ft. Those cars run really high boost pressures stock and can take upper 20's all day long on the stock turbo. The evo-9 model guys are seeing low 30s. Its a platform made for E-85
Right now I only know of one tuner making maps for E-85 and thats john @ Vitesse. I will say its just a matter of adding additional fuel onto you're map and making sure you have fuel mods to support it. What makes john's software/chips so incredable is his base tunes that he works everything from. So his e85 maps are great(I have two of them on my chip board). No to mention with the V-flex software it increases timing automatically if it can! You literally get the best of both worlds.

Anyone wanting a plug and play E-85 setup needs to look at Vitesse.

As far as injectors sizing gos. I've had the same questions. Sid seems to think my pump(044) with 3.0 bar fuel pressure and my injectors(83lb) are good for 22-23psi of boost before runnning lean.

I plan on running 21-22psi. I'll make sure to post up the dyno sheets when I get them
anything under 35-40 degrees

Adam, the energy is pretty close to the same IMO the EGT issue is more due to the non liner head I think.

As far as taking std 951 and converting it to e85 and turning up the boost. That is what I did initially when I got my car. I didn't use bigger injectors but used FP. The result was better than most 951's up here. I ran a 13.8 @101 when most stock 951's are in the 15's @ low to mid 90's up here from what I have found from locals who have ran there cars close to stock.

edit:: I should add though that my car had a MBC and an authority chip

wow thats interesting. I was nearly at sea level when I ran my 951 stock with LBE. I ran a 14.01@99mph. Bone stock down to the old paper filter. What elevation where you at?

blown 944

5800 ft

it does make a big difference contrary to somes thoughts especially off boost.

The air typically measures close to 10,000 ft during the summer.

Yeah I know it makes a huge difference in performance. Very nice. So stock for stock you were several tenths quicker and several mph faster. I was used the shoddy old tires the car came with. If I had some decent rubber I could have hit 13's bone stock but, I just never cared to go back.

I think in the future you are going to see alot more people following your footsteps in making the switch to E-85 early. It will allow them to run more timing and boost and be alot safer. If E-85 was around back when my car was running its old setup I probably wouldn't have eventually blew through a valve with that boost spike.

No need to apologize John, I was going to go buy a TON if you knew somewhere to get it for sub $13 a gallon

A little OT but at the strip how do you guys launch the cars?

blown 944

that is the $$64,000 question. Still working on it myself.

porshhhh951

we still need to get together.

porshhhh951

I would slip the clutch at about 3200ish rpms and mat it by about 4k. Seemed to work okay. No bog just squated and left.

blown 944

that worked with the small turbo, not anymore..bog ...or spin.... or spun clutch

I guess it is "my" $64,000 question

porshhhh951

Yeah unfortunately that was my launch technique with the stock turbo. I haven't had the chance yet to take the vitesse to the track. When I do i'll let you guys know what I work out.

yeh they realy are a hopless drag car my beemer ran 13.0/ 119 it makes me consider strait propane again i'ts apparently gone EFI now and as it comes as a compressed gas you get a refrigerant efect as you use it .I did mange -10C inlets on a +10 evening it also has a 110 or so octane ratring

I spent the last week or so working on my standalone maps for E85, Sid has been very helpful with the information he has shared with me. Today, after some more fine tuning on fuel and Timing I can say the my mostly stock 86, 75# injectors and 3bar FPR, 3bar MAP sensor, K26/6 is much stonger, than my previous chip/MAF and 93 octane. I am running 295/18's MPSC on the rear, 2nd gear around 5K I loose traction, first gears breaks loose much sooner. All I can say is this stuff is great and I can't wait to get my turbo upgrade installed. The current tune and mods listed above with E85 seems stronger than any other modded 951 I have owned.
