I was thinking of switching to e85 with boost but would still like to keep my nitrous for spool, has anybody ran nitrous with e85? is it ok and do you have to do a big fuel jet for the nozzle?
The effect of nitrous is greatly reduced on E85 vs on pump...especially on a lower compression motor. There is a big deal about how to get around it on the grand national forums...they werent able to get the spray to spoolup their turbos until one guy figred it out with some wack timing expermints. They were able to have such a late combustion and its so cold that it was still burning as it exited the exhaust valve and pretty much combusted in the headers. Turned out great for them.
All because E85 runs extremely cool as it is...then when you introduce the super chilled N20...it reduces the temperature so much that combustion is actually hindered. A really large shot can kill combustion all togethor.
But with your setup, a spooling shot should not cause you much of any issues...just slightly less power on the spray from what I have seen.
anymore info on this?
the guys on the e85 forums said I would be fine running nitrous on e85. if not this could be a dilemma....
This thread has given me some food for thought. I was planning to run a 100 - 150 shot on my N/A Cobra that I converted to E85 over the winter. Based on what's been stated here though it sounds like it would be a pain to tune and the results would fall short of what I was hoping.
Out of curiosity has anyone considered trying a dry shot of N2O? Perhaps pluming the N2O jet to the top side of the air filter ahead of the MAF? I have a JLT cai and a 90 mm Lightning MAF, it doesn't seem like it would be too hard to rig something like this?
plenty of guys running n/a with nitrous out there....do it. just remember you add 30% to the fuel jet you would use for gas. for a few....

ahead of the maf can be done but in small shot imo. the maf is electrical and once you start throwing freezing air at it in huge quantities it gets funky. Plus your just "tricking" the pcm to work differently which Im not a fan of.
Thanx for the info. I've done some searching around and haven't been able to come up w/ a lot of EFI info for E85 & N2O. Seems like a lot of carb guys and some tbi guys have done it successfully but I'm not sure how easily the nuts and bolts info transfers?
At any rate I will probably be doing the tuning myself later this summer w/ SCT Pro Racer and my XCAL2 so I'll just have to create a learning curve it seems . . .
just start with a small shot like 50 and work from there. The tuning should be similar to gas as long as you have all the right parameters in there.
Ive been reading guys aren't even pulling timing on the bottle...have to read more on that for myself...
