E-85 D2VE @ 1/4 mile track

I went racing for the first time on Friday night for some test and tune with my new car and engine.

1967 Mercury Cougar
3200#
501 ci 12:1 compression
D9 block .030 over
4.14 ohio forged crank
eagle h beam rods
diamond domed pistons
Solid flat tappet cam
dur 254 int, 264 exh,
cline 105 113
lift .624 .646
D2VE heads ported
1 7/8 hand made headers 3 1/2 flange
3 1/2 exhaust moroso spiral muffler dumps before rear tire
PortOsonic intake ported
Quick Fuel 1050 E85 carb
Duraspark dist recurved, HEI module, TFI coil
18 degree int timing, 30 total
JW bell
powerglide 1.76 fist gear 4000 stall
9" rear 31 spline race spool 4:56 gear
28x12.5 tire mickey thopson sportsman pro

Car ran very consistant at 11.5 for six passes.
Best was a 11.459 @ 115.93 mph
I was shifting out of first at 7000 and crossing the line at 6000.
I was too conservative on gearing, tires were not getting traction, and I need larger jets and possibly more timing.

You have a nice setup there and I love the E85 and D2VE combo myself. You have a lot more to get out of that build though and in my experience high 10. to 11.0? is there for the taking. I have experienced that running leaner than expected, all things considered, is the huge factor with E85 as it acts different than methanol. Most get the two confused. I will say check the ratio as even where I am located at the pump it is only required to be 70% min and ideally 85% but can fall anywhere in between and pass weights and measures. That leaves a lot of tuning to come into play. Again sweet build, and I hope that helps. Keep me posted on this ride. Michael

E-85

you have a very nice build and its all working together, I have been running E-85 for about 5 years and I have converted severial of my friends cars and trucks too, when I red your build the only thing I was concerned with is your fuel pump and fuel lines, E-85 really don't need as much pressure as gas but it needs volume and a lot of it, now most people think it uses 2 times as much but it don't at all, my stuff and all the ones that I have converted have been 25 to 30% more than race gas but I had to increase my fuel pump volume by 50%, now my fuel lines were #10 to the regulator and 2 #6 lines to carb and a #6 return, before I converted I had the same lines but no return line, also I had to remove the paper filter and install a stainless steel one and removed my holley black and put a BG280 on it, before I done the changes I just put the E-85 carb on I was told that I did not have to change anything but the carb, well it ran really good but would not MPH in the 1/4 mile but the 1/8th was ok, but when I changed my pump and added a return It took off and flyed about 6 more MPH, so check your pump and fuel filter for flow and let us know how it goes, hope this helps

E-85/E-70

when you test your fuel and you are jetted for E-85 and the fuel you got tests E-70 you will need to lean it out anywhere from 3 to 5 jet sizes

I always run e85 tested true. I have a holley hp pump and filters that are compatible with e85. I have -10 to the pump and 3/8 aluminum line to the regulator. Run 6psi and a -6 to the carb.
When I ran the car Friday I had a vaccume cap over my fuel cell vent I had put over it for transporting to the track and forgot to remove it. I guess the fuel cell lid has a small vent built in but still. Didn't run it lean but im sure it affected flow.
Im also running a FAST air fuel meter with dual sensors.
I was close for jetting. My jet kit only goes to 99. I have 90 and 98 in the car now. I need to get some jets thinking like 100-108 ordered.

E-85

I called quick fuel and got the E-85 jet set, it came with 100-110 and 4 of each I had my 600 HP Buick jetted at 104, remember if you have 600 HP the holley black pump will bairly keep up, I had the holley blue and my MPH was off, them I installed the holley black and it was better by a bunch then I put the BG280 and it ran like a raped ape, I faught this problem for 3 months because I was told that the holley pump was good enough but its not, the E-85 people will tell you that you pump depends on the HP of your engine, our E-85 site is www.raceone85.com go on there and check it out, you will find a lot of good info.
