Track update #2: 2018 3.0 Whipple, 3.875 pulley on E85 this time

[D98gt]

How did you do?

We got rained out, been getting hit with horrible weather all week. Car is actually on the Dyno right now

I'm curious as well, start a new thread with your updates.

Updates ?

Going back to the track this weekend finally!

You have id 1050's jms boost a pump and dw400 pump and are making 800 rwhp on e85?

Correct, ID1050X’s I dropped to a 3.625 pulley and went 9.81@145mph at 4100lbs so I’m assuming around 800+ rwhp.

Wow! I didnt think a dw400 and boost a pump with 1050s could go that far hp wise on e85. Congratulations

Is that the 6 rib or 10 rib belt setup?

 

[HRSEPLA]

It's the normal 6 rib belt

I know this is on the EDGE of enough fuel. It only worked with my BAP set at the 18Volts, I tried the 22v setting initially and had pressure drop around 6000rpms. The pump flows more at the lower 18v setting on mine.

How are you monitoring fuel pressure
Do you have an in car fuel pressure gauge ?

Also wondering if you have an oil separator or if it’s needed . Probably less of an issues with E85 but I wonder if oil is getting into the intake and lowering my octane ?

I just finished getting some street logs with my PBD E85 tune and fuel looks good per Lambda and STFT . It’s adding 2 % at 7500 rpm .
Same timing (21-22) as I was seeing with the race gas tune but seems more consistent ( I would still see some knock rarely with the race gas . It was inconsistent as would see -KR on most pulls and then a little knock even on back to back pulls )

Car seems more responsive with the E85 just driving around . Almost seems smoother but may just be in my head .

I am going to get it on the dyno on Monday and was going to compare E85 to MS109 but may not bother .
I assume they will make similar power since I am seeing same amount of timing . No way of draining the tank either after a pull . I bought the VMP “jump” but will have to disconnect the JMS BAP to run the pump .
Reconnecting the JMS will need it reprogrammed again and since I may not even be there when the pull is made not sure I trust the guy to do it right.
