At 6.8 ms you’re definitely playing with fire my friend… nice numbers though.

I would start blending until you can get the AFR around .83 and Injector MS under 6.0.

Thank you! My tuner and I are discussing options. blending is probably the best option. Not sure yet.

Thanks King!

Does the window change from stock lt1 injectors to the +30.s ? I've heard mixed things on it. I've heard that 6.5 MS is ok?

You think it will lose much power by blending and getting the MS under 6.0? I thought about dropping psi from 12 to 10 but don't really want to do that. Don't want to run meth either.

I blend and run E70. It’s like 6 gallons of E85 and 1 gallon of 93. Easy peazy. The most annoying part is I have to run another credit card transaction for the 1 gallon of 93.

Yea I blended before I was forged and had lt4 fuel components. It’s definitely easy peasy. Definitely sucks having the 2nd transaction for 1 gal lol

E60 will give you virtually all the benefits of full E but a good bit less strain on the fuel system. Larger injectors and HPFP can help you get more fuel in the cylinder during the injection window. So you’d keep the same ~6.0 ms threshold, but you’re able to do more fueling and make more power. FWIW I’m DI-only at my power level.

Ok makes sense. I’m waiting to hear back from my tuner and see what he suggests.

That’s impressive for DI still. I have the LPE BB, +30’s, Fore innovations setup. I’m running the Btr stage 2 blower cam and I know I lost some fuel headroom there.

Yeah +43 cam (I’m stuck with a +32 currently too…ugh…) and +52/+65 injectors are the meal ticket. Nothing wrong with +30s but E gobbles up fuel system headroom like PacMan on roids lol

Mikes port setup is interesting. I might go that route if I ever decide to go for crazy HP. I have problems with traction now at Id guess somewhere between 600-650rwhp. Haven’t had a chance to get on a dyno yet. Can’t imagine how crazy it is with your setup. How are the 315 R888R holding up? I’m looking at throwing those on soon….

I use the Smoothboost to tame it down for the street most of the time. Probably in the 700-750 WHP on the street most of the time and the R888Rs do a great job for the most part, especially if it’s really warm out. From a 40 roll they absolutely rock. I’ve never tried to hit them hard from a dead stop at full boost as that’s a waste of time. Even on my 17” beadlocks I still launch in 2nd gear at the track.

Nice. I don’t expect them to hit from a dig. Built my car for a road course so I’m not concerned about 1/4 mi times, but the 305 Goodyears are pretty good but have to be hot. Anything under 40-50mph they lose it. Hoping the R888R help that a little bit.

Sounds like the R888Rs should definitely help over your current setup.
