Probably. The vac advance looks less complicated electrically, but I know the 3FE dizzy has been used with mega squirt & TBI systems. If we can get a signal that the Holley approves of, we’re golden.
Good actually. The 2F setup will be ready to test next week.
On this motor, we’re going to fire it up on vac advance for simplicity. Once we know everything is good, we will try to set this one up for computer control of the timing using the Toyota (carb) dizzy & coil.
I’ve seen this video before but watched it again and took notes to try and understand what’s going on. This guy successfully computer controlled a large cap HEI with the Holley. That’s pretty much what a DUI is, which is what we’re running.
Distributors, specifically computer control, seems...
TLDR: we need more timing to make maximum woopow, and we need the computer to control it. WOT pulls never activate vac advance, so never get off to a strong start. That is why the harder we tried, the worse it got.
I have been in that rabbit hole for a a few days now, and am pretty confident...
We put it back together and drive it. It seemed the same.
We do all notice a flat spot as you approach WOT. We got rid of most of it when we added timing earlier in the process. We had some rattling under 1800 rpm lugging in 3rd so we stopped adding timing, but nothing at high rpms.
In talking...
The dyno runs were considerably gentler than the off-camera 5K flogging we had been doing during testing and break in. We had no idea what was going on because it didn’t sound any different, though one run almost sounded like a stumble or misfire.
The drive home from the shop added to the...
Subsequent pulls were down considerably on torque. HP was only 100. Dyno guy looked nervous. Each pull got worse and worse, the harder we ran it.
Not sure what was going on, we packed up to go back to the shop, no idea if we had engine damage or a sticking brake caliper or something else.
I was more than excited when I saw the screen. We saw 189 ft-lbs at the wheel, which is a nice increase over Nolen’s Warthog, which put down 166
It only made 127 hp because he cut the run short. It probably would have made another 15-20 if he ran the RPMs up.
Here’s the Warthog vs a stock 2F...
We have the truck back where it was, which means we’re almost ready for the dyno. I just need to be able to connect to the Holley software.
This time, we’re almost in the clear. We can connect Sniper to laptop, but need to update the Holley Software on the laptop itself before we can proceed...
Here’s a little more spirited romp on the throttle, blasting up the viaduct that carries us safely over the hood instead of through. This was a second gear rolling start up to the speed limit. 60% throttle max:
Back to the story…
Recap: Dyno try #1 resulted in a dead Sniper before we even started. Red is back at the shop. Fred Smith and the boys are behind the scenes, rushing a Sniper for next day hand delivery.
Next day, the Sniper shows up. We get it swapped over and take it out for a test drive…...
One of the last things I was supposed to do was bring a laptop with the Holley software. I did that, but spent so much time I never got Seminole to connect to it tho.
This Sniper is the same one that came off the truck, so it wasn’t from a recent batch. When I tried to connect, I had an error...
We’re at the dyno shop bright & early the next morning and are met with large horsepower and an even larger pit bull.
Our intentions are pure, so we’re allowed into the back.
