I want to stay conservative on timing and make the power with boost but that kind of increase with 2 deg would seem to indicate the motor really wanted it.

Parish, what are you running for fuel on these runs?

Choda · 04-12-2021, 07:52 AM

Wow, yeah Id say the motor really liked it.

Did you get a chance to drive it around yet?

parish8 · 04-12-2021, 09:32 AM

E85 fuel and yeah i have been driving it. Drives great. Can doesn’t feel or sound large at all.

I have the idle set at 850 and it seems too high. I need to work that down.

Off topic but wondering what's your race weight on that little beauty?

Agree and he is not the only one I have heard say that. I believe 15psi on E85 should be able to run 20-21 degrees without hurting anything. I would add a degree at a time until it quits responding then pull that degree out. Keep the AFR around .81-.82 lambda. Awesome results either way.

I am pretty sure this is without a driver.

parish8 · 04-12-2021, 11:27 AM

There is conflicting info on timing. I did a timing test before with the stock cam, it might even be posted up higher in this thread. It picked up a ton from 16 to 18 and small amounts each bump after that. Made it to 24deg and it was still picking up. Got scared and stopped there.

I am leaning toward 18 at 15psi and drop another 2deg for each 5psi. Keep timing at peek tq something like 4deg less than up top. This is not set in stone.

KingLT1 · 04-12-2021, 01:23 PM

I know I gained 1 mph trap going from 18 to 20. I haven't tried going any higher but I believe you. I think 18-20 is the sweet spot.

laynlo15 · 04-12-2021, 03:01 PM

Haha, I was running 26-27 degrees on MS109 and 16 lbs of boost at one time.

KingLT1 · 04-13-2021, 08:39 AM

Yea well I ain't trying to burn up my SBE. lol

Come on King, you can run that much timing... well, once anyway...

parish8 · 04-27-2021, 07:06 PM

I have been playing on the dyno. Here are a couple of runs.
One with flat boost the other with flat tq On the track I will probably push the boost up with rpm like the red graph.

I tired the track last Friday and piped a coolant line and made a giant mess. Now I will just run water to help reduce the mess if that happens again. I will try the track again this Friday.

danhr · 04-28-2021, 07:17 AM

i was really hoping to see results of the flat torque curve..... really intrigued by your idea behind it

Choda · 04-28-2021, 04:53 PM

yeah... what happened to flattening the curve? Looks like you hit the scramble at 6500 and she pulled till 7400 =]
