I'm thinking ahead about higher boost and I've had good luck with E85 in the past. Has anyone here though about a conversion? Injectors, fuel pump, etc?

Given Jay's (philly) ETs and Traps, I'd estimate that he is putting down around 700 crank HP with nitrous, so the power can be handled by the tranny so far. I'm thinking about more boost and I want the octane and cooling.

Thoughts, knowledge?

 

Do it.

 

Lol, The manual states "the use of Ethanol or Methanol above 15% will cause irreparable damage to the fueling system and engine components."

 

Yes for AJ33/34 and earlier AJs, but AJ133 is direct injected and this makes things different. I do not know how much free space stock injectors and fuel pumps have left. Can be difficult to find bigger capacity aftermarket ones.

"The fuel system employs 6-hole injector nozzles and
peak injection pressures of 150 Bar (2176 psi) to achieve
these objectives."

AJ133 engine manual tells about fueling system, pages 40-53.

My calculation gives 800+ hp from the crank with 150hp nitrous.

 

Well, look at this thread...made my day seeing this!

Ah-hem, I'll take 750 @ the crank But I digress...

Of course it can be done, GTR's are converted to E85 on a regular basis. Just, as usual, our stuff would probably be one off. Can probably get injectors made, throw in some bigger pumps, change the lines, etc.

Then just deal with the ECU part. I'm not sure we can spin the blower fast enough to *really* take advantage of E85 can we? Or drop on a bigger blower to cram more air in...

 

I'll take your TVS R1900 blower when you are done with it.

 

Screw the manual. I'm sure you can do it... uncharted territory. Collaboration. The only way to keep it exciting.

 

Yeah, easy to say after your partially E85 tuned and barely modded GTR destroyed my SVR last night.

 

Oh I thought you just wanted to hear my exhaust

 

Bast@rd.

 

I'll ask my tuner if he or anyone he knows wants to try tuning your SVR w/ flex.

 

These boxes have my Ewhatever "E0-E100" tune

 

More info....?

 

It's flexfuel system. V8 needs two boxes. So you may use
any fuel/E85 blend. Boxes are connected to the fuel injectors, ECU and
ethanol content sensor on return line. You can monitor ethanol %
as well as injector duty cycle from any Android device.

 

Wanted to surface this discussion as haven't heard any mention of E85 otherwise.

It's never advised to run a high mixture of E85 fuel on a car without the proper modifications, but many unmodified cars produce great results with up to E30 fuel. You can achieve this with a 3:1 mixture of standard E10 91-octane and E85, netting roughly 30% ethanol content and 95-octane.

Has anyone with datalogging capabilities given it a shot?

 

I don't have direct personal experience,
my knowledge is limited to the following information:

Jaguar state E5 and E10 fuel is ok but not higher alcohol contents.

I am aware that ethanol can increase octane rating of petrol (gasoline), however my understanding is it has much lower calorific content per unit volume (less energy content) so engines designed to benefit from high ethanol levels must flow considerably higher levels to develop higher power outputs.

Stoichiometric air fuel for petrol (gasoline) is 14.7 :1

ratio for pure ethanol is 9:1

Other considerations are lower lubricity with regard to fuel pumps and injectors.

In my country (UK) at least one 99 octane (RON) is an E5 fuel.

 

How did you determine the actual octane rating of the E85?

There's little/no evidence that these cars can take advantage of anything higher than 95RON/91AKI fuel.

 

This is true. If you haven't told the vehicle that its running E-85, its not going to advance timing and take advantage of the extra knock resistance. The car would however attempt to adjust fuel scaling to compensation for the lean condition you'd ultimately create; if of course you had enough injector flow. Datalogging a stock tune running E85 would ultimately tell you nothing.
