Dyno pulls tomorrow E85 Pulls

[Justin]

I have an appointment for tomorrow to make three pulls on the dyno. plan on doing data logging at the same time with my personal laptop for shaun to make the final tunes. Doing this in light of my friend getting a reckless driving ticket when he went out to do his data logging......81 in a 45....safer on a dyno and cheaper in the long run (and a good excuse to tell the GF so I can pay for the dyno session lol) so check back tomorrow evening I will post the results.....yes I will take video.

Sounds good, Cornholio

 

[Justin]

lol cant wait to see what it puts down. its great air here now for the dyno as well

 

[Senderofan]

Can't wait to see your results...I suspect they'll be pretty good even though your fine tuning the set-up. Thanks in advance for sharing.

 

[Justin]

no problem. need to go and fill her up with that sweet corn juice in the morning. the car right now in the cold is just so punchy that 1-3 are just about useless since the temps took a dive here.

How many revisions of the E85 tune have you done to date? Very curious to see what you're putting down. Mustang or DynoJet?

 

[Justin]

no revisions on the tune running the base E85 tune. its a dynojet at least thats what they told me it was I will find out for sure tomorrow. the wot logs are running clean shaun said just wanted a fresh tank before he sent me the final tunes. I have a decel tune that he sent me for the e85 but I didnt like it so I switched back

 

[Sesshomurai]

Look forward to the results beavis.

I thought you were going to do a dyno with a normal tune and CIA too. I'm still curious about a results of the E85 but I've never seen it in my area. For selfish reasons I was hoping for the less exotic. LOL.

[/quote] I was until I got the e85 tune. Don't want switch back and forth on the fuel at the dyno. Might try 93 tunes later. This is mostly for just the data logging.

That cool. I totally understand, I was waiting on the normal tune results for future mods. I hope the corn gas works. Doesn't the MPG take a beating when you use e85? I mean it cost more right? CO's are higher too? Just wondering.

its cheaper at 3.30 a gallon vs 3.99 for 93 7-11 gas here in va beach. it does take a hit in the mpg I avg 14.4 with the gas with e85 on this first tank (lots of hard pulls through the gears mind you) 11.2 mpg. both from the computer estimate. CO's are slightly less (.5%). the main benefit for me is that its like running race fuel for pump gas prices. 109 octane. cools the air charge to boot. car runs smoother and cleaner (deposits wise).

I'm not sure there are hard and fast numbers....but I've seen 15% less fuel economy with E 85 thrown around....also have seen some 20-25%...which seems a bit steep.

 

[CaliMR]

Is the mpg display still accurate with the bigger injectors?

 

[Justin]

Well it was getting the usual mpg per the gauge Before and after the injectors on 93. So i would guess that yes it is

ok back from the dyno. sae corrected 404rwhp and 355rwtq. uncorrected numbers were 423rwhp 372rwtq. The owner said its the newest version of the dyno jet and reads much lower than all the others out there. said it reads more like a mustang dyno.
run conditions are:
73 degrees F
humidy 15%
30.38 in-hg
sae: 0.95

uncorrected dyno sheet (sorry had to take a pic of the print out)

Sae corrected all three pulls

pretty stout dip on the dyno graph on the big end aroun d what? 6500 or so?
what did the knock look like at or around 5500 to 6500?
how about a/f ratios in the same rpm area?

that killed the power she would have shown on the dyno...it looked like maybe a 415 or so rwhp run if that dip was not there...

 

[Justin]

Nothing on knock just looks like The timing was pulled back on the base tune. Held 25 total timing with a slight dip to 23

 

[Boostd4]

So this is still the base tune then? Looks pretty close to stock numbers on 91. Hopefully there is a little more power once the tune gets cleaned up.
