New personal best... 6.5 @ 108.1mph 1/8th mile

[BEATAV8]

Steve, You can't just order one. You Max out the 120's yet? That's a prerequisite.

Ha well maybe saw some 97% ish duty cycles when the weather cooled, but I'm still fighting false knock issues. Just swapped the valve springs for something a little stronger hope that fixes my chitbox!

LEAN is where the power is.. Lean and Mean

That's not on the gas scale. Most people are using scantools and widebands calibrated for gas.

Well I know some of you here have seen or heard of my car with previous E85 setup, but due to tranny problems ive been down since late march. I lost interest with the car for a bit due to lack of money but I stayed focused and finally got it back on the road last Thursday night with the help of gabby Rojas tuning the car.


Since it's last time out in January this year, it ran 6.6 @ 105 with a 1.50 60'ft @ low 30's psi.

- old fuel system was trickflow 120lbers, dual pumps, -8 feed to stock fuel rail.

As of Friday night we went out and only got one pass and boy what a difference.

- car now has 160lb injectors, same pump, same feed, same rail.

And it ran 6.5 @ 108.1 with a crappy 1.6 60'ft at 28psi.
After the the run we looked at the file on the PL and noticed WOT timing was at 18-19 degrees timing so this thing wasn't even running any where near its potential.


The a/f is at 11.5-11.8 and inj duty cycle is around 55-60% so more boost soon.

Big thanks to Eric Marshall for his help.

What was your duty cycle on 120's? Were you out of injector or did you have a problem with the trickflows?

Thanks

Bryan i think he wanted a bigger window for safety he told me his IDC was a little high.. So i actually bought his 120's some time ago.. They look real good to me.

I am buying new injectors, I just needed to know what kind of duty cycle he was seeing. If the 120's will get the job done in the mid to high 9's...
The 120's are much more affordable than the 160's.

Not to interrupt or hi-jack, but 160's are available as hi-Z? I thought you had to go low-Z in order to get bigger than 60's?

While I can't speak for the 160's, I know they have 120's in high-Z now.

My part throttle SREET (economy) is more like 18-19 to 1 AFR. I'm off the chart

congratz on a new personal best! Gabby helped me get my car running last night ...just got in some fuel lines hoping to join you guys out there soon!!

 

[TurboBuick86]

went back out friday night. was nice cool weather. Messed with timing and car ran a crisp 6.43 @ 108.9 with a 1.52 60' ft same boost.

The photographer managed to get some pics of me which I plan on posting in the pic section...
