A whole herd!Also congrats on 520whp, that's quite a few stallions.

That's the beauty of this combo. It drives like stock.Driving back home from the Dyno... I was struck that here I am, stuck in rush hour, driving a car with over 600hp at the motor and it feels like a sporty but normal car....
You have access to 99% pure ethanol?Not down here!! But my mechanic is mixing his own e85 and its getting a little more affordable for me know.
That's awesome. I think that's all racing ethanol is, 99% pure ethanol mixed with 15% race gas.Its 98% ethanol from sugarcane.
I doubt there is a performance advantage, its more of a consistency issue.The 98% Ethanol based e85 is about 8 bucks a gallon, which is about the same as my 98 octane race gas. regular pump 93 is about $5.50
Prepared, imported E85 race gas is super expensive, thats about $17 a gallon. Right now my mechanic is making a Dyno comparision between race E85 and backyard e85.
I was surprised to see that Sunoco 260GTX has the same additives as the typical octane boosters.There may be some different additives in the race E85. You may be able to glean some info by comparing the Material Safety Data Sheets (MSDS) for race E85 to regular race gas from a couple suppliers. However, as most of the "recipes" are considered trade secrets, you'll only get general percentages of hazardous chemicals, but it gives you a ballpark idea.
Actually, it looks like Sunoco E85-R has fewer additives listed than their 260GT or 260GTX.
My temps with the last motor (basically the same motor as now but not ported) were good.Yup... here are the results on a new Mach1 10spd. the car came in with a custom exhaust, LTH and no cats, and tune with 478 rwhp. using a homegrown e85 got the car to 495. With the Imported race e85 it went up 500rwhp. So the home mixed E85 was pretty decent.. But it would depend on who mixed it etc.
Will wait to see Sal's numbers and the engine temps before looking seriously E85
Its all about efficency....he gets the most of of every drop of fuel.The one thing that has me mystified, is why is the fuel consumption so much lower then before. Its really quite startling... its like completely different. So either Shaun has a magic touch or some thing was really wrong with the car before... OR BOTH.
With out trying to exaggerate and tell tall tales... track consumption is down at least 20%. I asked |Shaun about it and he said the motor is more efficient now but the drop is more then you would expect.
Last weekend I had 1/2 a tank of race fuel in the car. I drove the 100k to the track, had two short sessions and had plenty of fuel to get back home.
I know, I hear everyone crying that e85 fuel consumption is so terrible....and I'm like, "its really not that bad"...but you how it is, what do I know right?Who would have thought that you get 50hp more, and 20% less fuel consumption. Impressive.
I've run 35 minute races at 8K rpm with 15 gallons of fuel and never run out, so it's not that bad.Who would have thought that you get 50hp more, and 20% less fuel consumption. Impressive.
Gotta be really similar, and that's close enough for me.Tuned in and waiting for your numbers! Lets see what these terrible twins do with different fuels.
Depends where its measuredCurious as to what is going on here. Oil pressure usually results from restriction. You increased line size, therefore increasing oil flow and should see a drop in oil pressure, no? Where is your oil pressure sensor located in the circuit?
Bingo.Depends where its measured
