Winter changes on the AMX. Are you going to make any changes on your race car?

I have a Pro Systems gas and a Pro Systems alcohol carb. They are both great carbs. But I know SEVERAL guys using E85 on the street and braket racing them. I have ridden in a couple of them on the street. Mark Sullen's E85 carbs run flawlessly he has got the E85 fuel curve down. I'm not downing anyone else's products and I don't own any of Mark Sullen's products. But there's hundreds of people running around with his E85 carbs and singing his praises .
I also have a gas pro system and a e85 carb.Gas carb is great and couldn't ask for a better carb.
The e85 carb...well still a work in progress.It doesn't want to leave below 2700 rpms
My son bought a quick fuel 750 e85 two years ago and after changing to blue pump cams it has been flawless.
E85 is around 3 dollars in md and we just fill some drums in the summer months.It test 87 in the summer and 83 in the winter where I buy it.
We are bracket racers so the cost is great,we run cooler temps and it's consistent.
