e85 making the switch

And if you ever find your way to Vegas I will buy guys a beer or five!

Put the car on the dyno thursday and tried to dial it in better. Put it on the track friday night. Finally broke into the 11s. Had a few 12.1x passes first with fairly soft launches. Its still a work in progress, having some boost creep issues on the big end that is causing some knock. Actually lifted a bit before the trap on the 11.85 pass saw some Kr on Scanmaster. More tuning required but closer and Im getting the hang of tuning the car. IDC at 75% with the e85 and 80lb injectors!

Nice!!!

Mike...have you got a PL file from any of those runs?

[Forzfed]

Nice!  What boost and timing were you running?

Oh, yeah, I tune with the knock sensor and add a couple % more fuel once I find the borderline where I cross into detonation...I like a little margin.

Whatever that reads on the wb band or the stock sensor at wot is my "magic Number" but it might not be yours

Great advice, Steve!  That is more or less what I do and when at the track tune it for the highest mph, then you know what the car likes.

Here is 2 PL files and the slips for them. Pass 2 was 23/19 timing and Pass 3 25/20 boost about 24-25lb. The last pass (11.85) my laptop battery was dead. I opened my dump and ran 26/19 timing. I ended up with boost creep on that pass up to about 28lb at top of track. I thought after cutting off my Flowmaster and installing a Dynomax Ultra flo it wouldnt creep that bad with dump open (wrong). I saw the Kr on my Scanmaster before the traps. I still need to get it dialed in better. No more kamikaze passes without the PL! The 26 degrees of 1/2 timing on my last pass really woke up my 1/8 mile on the high 11 pass. The track was dead hooking with the prep. Also I still sometimes log knock on my trans shifts which I assume is false.

Since the track friday I have turned down my 3/4 timing to 18 degrees and changed the 3/4 AFR target to 11.0 from 11.2. Also added WOT fuel. Would like to get on the track one more time before its to hot!

You're showing a ton of KR in third gear...and it appears real.

[Steve Wood]

Don't have any experience with E85, but if it works anything like the old alcohol cars did, you are skating on thin ice with that kinda timing....lead s to pre-ignition which is way more deadly than detonation

[Scoobum]

I just leave the high gear timing on Erics default setting...and put the boost to 'er.

[trashmechlv]

I actually have been pulling 3rd gear timing because of the knock. Erics default timing was 22 in 3rd gear. I will get a handle on the Kr before I run again.

Ran TnT twice in the last few weeks. Temp was 100 degrees and DA was about 5100 both times. found car doesnt make any more power over 25-26lb boost. Got the knock cleaned up, still showing some on the trans shift occasionally. Im done at the track until the fall, the heat is here for the duration  . The E85 did seem to keep the car from feeling heatsoaked.
