I wonder if there is too much ignition timing, was it tuned on dyno?
IMO for the power your looking for, the reliability and the type of heads you are talking about, there is no reason to lift the valve over .750-.800".
I will tell you our setup and hopefully it helps you. Ours is a Pioneer front mag drive which I've been told is extremely similar to...
If I understand correctly, you richened it (because you allowed the port nozzles to come on) and the flames went away?
How about things that I can do without wrecking parts?
What are all the different ways that detonation is watched/sensored? Such as: -knock sensor -cfm of blowby -watching the rod bearings
Do these use regular big block chevy cam dimensions? Or are the cam bushings larger? Also, are the cam drive parts the same as a big chevy?...
Is the ignition timing stable? Caused by too much cam endplay, something else is loose (IE cracked rollpin, sloppy pin hole, etc). What mag...
A couple weeks ago I had a pump go bad real fast and it resulted in a broken blower belt, 3 melted pistons, bad head gasket, warped valves and...
Have you ever heard that changing the firing order on a blown BB Chevy would be easier on #2 and #4 mains? Anyone have real life experience...
We are all not quite on the same page. In my comparison, both runs are with the poppet opening, its just that one is opening at a different RPM....
I've done it on one of my other engines. I should not have called it a High Speed but regardless its a spring poppet.
Correct, so if you open it at a lower psi/lower RPM it will lean at a lower RPM without effecting the higher RPM, but in this particular case (for...
This is what I thought too and I know I've checked this on one of our other engines (on the flowbench) I have my suspicions that I'll check...
Teach me what Davenport's software can do. For instance, recently I wanted to lean my engine at a lower RPM but not at a high RPM. I thought to...
thermocouples in the combustion chamber About how much does it cost to put the thermocouples in the combustion chamber? I know its about $10k...
I built mine from scratch and I would have to agree :D How to build depends a lot on what you want to accomplish. I wanted to know about my...
Can you explain how air bubbles can be "produced" inside this captured enviroment? I would like to learn. Or how could one test this or...
Some people have said that those 90° fittings in the picture can cause air bubbles, I personally do not believe that. Do you think that is...
What are you doing with them (drag racing, tractor pulling, boat, etc) and what kind of RPM levels are we talking? We run BME now, but for 30...
