Really sweet setup as everything I've viewed on your car. Back in the late 90's I had a 90' Saleen with an A trim Vortech, 110lph pump in tank with a T-Rex inline. The T Rex howled like crazy! I went to a larger pump in the tank, the increase in volume at the back of the inline pump cut the noise in half.Nice, huh?
As my fuel gauge is not reading correctly I keep accurate usage records of my fuel so I know where I am at. I am buring .4 gallons per minute of E85, sometimes a hair less than that. Thus 30 minutes is 11 to 12 gallons. Hopefully you can find a different option than carrying fuel jugs in the back seat as that is very dangerous. I am fortunate to trailer my car and have an auxiliary 40 gallon tank in my pickup bed.How much fuel are you guys burning on a 30 minute hpde session. I have an S550 with flex fuel. Car runs better on E85. But I would have to bring it with. There is an E85 Pump 5 minutes down the road from my local road course. So I can run over there in between sessions and/or put 2-3 5gal jugs in the back seat.
If it runs cool enough you can close up the grill opening a bit and trade some parasitic drag for additional downforce. ;-)Lots of great info here and I have been contemplating switching over to E-85 since my son runs it in his EVO 9 with no issues. Nice info from ls110 and Fabman , because a fuel cell is in my future ( maybe 2020 future, though ). I seem to be using about 5 gallons in a 25 minute NASA race , but at $10.00 a gallon for 100 octane , E-85 makes huge economic sense!? The car runs cool enough , but the benefits may prove useful on a super hot Summer race? Look foreard to seeing Godzilla at the Mustang Roundup and am planning to lasso his rear wing , so I can keep up with him around the track.
I'll save you some time. Just got off the phone with him. Not sure what car you're in, but for my 2011 GT, he said flex fuel is doable with nothing more than injectors. Determination of ethanol content relies on a/f ratio. I triple asked him just to verify there was nothing else needed and difference concentrations of ethanol are no issue.My plan is to contact Shaun at AED here in the near future to ask that exact question.
Let me start by saying I have been on e85 for many many years and would have it no other way.....however:I know this thread has not been posted on for quite some time but have a question and looking for input please. My 2012 GT is tuned on E85 - 2018 manifold, 47lb injectors, Pypes long tubes , cat delete with Pypes off-road X pipe. This was all done prior to me purchasing. The previous owner said it dyno'd at 437WHP and was going to be a street drag car. I have no Idea what is on this car, partially nervous and just need to know my car better than hearsay. I have a dilemma and do not know if I would be able to transport extra fuel. From what I am seeing I'm going to need maybe 30+ gallons of extra fuel if I include the drive to and from the track ( 45min each way) and would maybe end up doing say 3 20 min sessions. If and when I decide to track I can not seem to find any fuel stations that are close to Pitt Race. If there is one that I missed I would be concerned of their E85 content. I'm trying to use the same fuel station right now and will be purchasing a tester just to make sure that the station is consistent . I spoke with the original tuner looking for information and maybe who or what program was used but really could not get any info from him other than I would loose 15-20 hp if detuned to 93 and wanted me to get my car to the dyno again.
I would be brand new to track. Does this look like a reasonable plan. There is a local tuner that has a dyno and works directly with Lund. I have to get a custom tune done one way or another before I push the car for my piece of mind and to be safe. I know it's going to be expensive but it is what it is...
Contact Lund before I even plan to schedule a shop appointment and see if they can do the below...
1. Get the car to the tuner with tested E85 in the tank and have Lund do an E85 tune - 6-7 gal in the tank.
2. Add a fuel dump program to so I can drain the E85 while I am there. Prep for attaching the drain hose way before I go to the shop and have empty tanks ready.
3. See if Lund can do a 93 tune while I am there - Take 5 gal of tested 93 so Lund know the actual content.
4. Potentially leave the car at the 93 tune with the decreased HP until I gain some track abilities. I don't think the detune would be a bad thing for me since I am new. I do love the smell of the E85 when stopping at a red light though! There's no doubt the car is tuned for performance and hates lugging below 2500 RPM.
Thoughts, Comments, Ideas, Alternate lines of logic ? Any experienced input would be greatly appreciated!
Thanks in advance!
