Some of you may remember a post from back in early July by Mr Angry titled "Guess how much HP gain w illegal springs"
In that thread there was a side conversation regarding not using high tension springs in the plate engines and phenomenon I thought I identified. The conversation continued regarding beat frequency oscillation between myself and astglenn.
Whelp for all you doubters out there, I think I've dialed it in.
This is a AKRA legal clone with a certain spring, a certain valve, and certain amount shimming. (and yes Al, jetted just right) That info I'll keep to myself, as it's taken tons of work to get this right. (including building a spring "dyno") I will hint to this, it will easily pass spring tech.
Peak HP moves to 5500 rpm in a purple plate engine, and 5250 in a green plate. YES it's repeatable, and with the amount of pulls its taken to dial it in, I'm very confident it's stable for the long run as well. Although it is hard on the valves.
Geared correctly, this one is hard to out-horsepower on the track.
These screen shots are a purple plate clone.
