Dmitri's 2015 Update: 657AWHP // 681 AWTQ w/ DR750 on E85+Meth

[futurevr4man]

I've hit more Hz numbers and load numbers than that without hitting cut. 3800+ and 296+ IIRC

Last I heard, the limit that Greg thought existed was incorrect all along. I openly admit that I am quite rusty on all of this though... I haven't messed with, or looked at, the tune on my car in years. Hoping he can chime in on this... I'll text him.

But worst case... there IS a workaround...

If you make it out to Ohio, please make it public knowledge, or at least let me know. Would love to shoot the BS! (I live in Dayton ATM)

lol last July, we hit 3947 and 294.x, so it is not that. However Matt said it sounds best. We may or may not try this band-aid workaround since he is now off from work.

And yes, I will definitely make it public if/when I head there (or anywhere else out-of-state with or without Mark lol!)

Just be careful the fuel cut is not actually pre-ignition. You may have to run a 9 or even a 10 series plug pushing these turbos that hard.

There seems to be some confusion. The stock MAF loses count around 425-450whp. Can't remember the exact hz anymore. Might have been 2600hz.

The code itself should be good for 6400hz. You run out of load though. Not that this is a big deal honestly. It just sit and collects the base timing value off the edge of the map.

I will say that Mark's and my VR-4's "aggressive" tune does not go beyond 26*. I will follow-up with your question once Dmitri revs out to 8k lol.

ECU advanced to 26* at 6.7k and held that solid up through 7.5k That is about all that I will say though lol =P

Thanks for the info, Greg.

Appetizer to start! (FF to 1:25 if all you care about is the pull lol)

[futurevr4man]

Can't see the vid at work :/

But my gut was correct... there is no limit. I am genuinely curious what the F/C is now. Are you spraying so much meth that you are drowning out the flame front?

[new93TT]

very nice

[bboyalan]

The F/C was definitely a random fluke, but it was real in the logs for the duration that it plagued us.

We DID trump our numbers yesterday, but I am waiting until tomorrow to post up a more detailed update when Dmitri will make a hopeful attempt to get the EVC6 to hit 32+. There is still plenty of fuel available to crack that 700 mark lol. He honestly admitted that the car is both satisfying, smooth, and scary as-is, so he is personally content.

"We gave her hell this year! "Final" number is 678AWHP VD SAE (690 U/C) @29psi on E85+Meth! This is the THIRD most powerful TD04/DR750 3/S in the world

Next up: Street pulls vid and dragstrip visit!"
