If you can make 800 plus on a dynojet and be do nlts I think you could pull on liter bikes up top. You can always try and find out. Haha. Looking good tho. Wish I could get a ride in it some time. We should have a mini cruise some weekend.

I am sure the setup has 800ish in it if i go around 40psi, to get a solid "real" 800whp on a dynojet. Right now these are just virtual dyno numbers and I don't ever put a ton of stock in them. The car is for sure fast and I think is for sure 700whp+ but not sure how deep into them.

The X doesn't have true NLTS yet, you can do some stationary rev limit stuff to get it but I'd prefer to wait. Or shift ron style, power shift it.

I will give rides out when it's ready to beat on and consistent.

Nice power! Have you been getting e70 still at the pump? Just curious, cause once the mix changes it is going to lean out even more, which will mean more tuning. Or are you already planning for that?

[Murlo26]

I dunno...even here we didn't see a count of knock, I think we are on real e85.

Same road as others....lean is mean lol. It was the 1st pull on rescaled map, we fixed it right away.

We will tune more if it starts going lean. I monitor AFR's pretty close.

My zeitronix has been reading about E73/E74 down in Mankato.

800 WHP and it looks like you have more pump left :)

Murlo you really need an ethanol tester haha. Tune to mid 11's on E70 and let'r buck at low 12's on real E85. :D

Edit: I forgot to mention, when I had fuel pressure issues on my V, it would go to 15:1 and never see knock, that was spring so it could have been less then E85. Granted it was only running 10psi but still, I wouldn't guarantee you have full E85.

These guys have a pretty good point, there's no way we're on real e85 yet...you should really richen up the tune so when you do see real e85 AFR will rise to where it is now.

I will monitor and adjust as necessary. If it starts climbing we can adjust later.

My car seems to run WAY better at 12-12.5AFR's and that is not uncommon for E85 from the stuff I have seen. That being said I still like aiming for 12 flat like we have now. Then when it starts leaning out we will adjust to keep 12 and then I can leave it for when e70 comes and it will richen up.

Are you sure your wideband is reading correctly. The power difference between 11.5 and 12.5 shouldn't be much and the start of your run looks very lean, you sure it isn't reading a point leaner than it really is or something?
