Hot spots in chambers due to sharp combustion chamber edge from surfacing. Boom.

Sorry for the hijack as well.
Scooter, those are the ones I run on the race truck.  They needed welding to fill a dead spIot inside, but I was able to port them for 50mm carbs.  They're basic 45 DCOE manifolds.  The carbs did NOT fit with the brake booster in place.


That's good to know. I was wondering about the unported port size. The cannon intake I have is ported paper thin and I feel that it's still too small.

I don't have a booster so that's fine, but if this intake shorter than the cannon one, that would be welcomed as my stack on cyl 4 is about a half inch away from the brake resivoirs.

They do run a bit smoother with projected tip plugs, but can possibly ping more as well. I've gone to the extreme (ngk race plugs that are 11 heat range). Good nitrous plug but light throttle cruising or putting they foul up. I'm going to have a "street set" of plugs and "track day" ones this year.

I have custom 89mm pistons.... you could just use z22 pistons if you wanted to.

 

or if u went custom pistons, there is a Mitsubishi rod that's really close to useable for a datto in 156 length if you want to turn your crank down to Honda/Mitsubishi journal size

Pierce makes a decent one? Better than Cannon anyway...

I have a RallySport that is badass. It raises the carbs up higher for a straighter shot at the valves, and way better brake master clearance. PM me if interested
 
 
 
Sorry for the threadjack Matt.  ^_^ .


I'd like to see some specs on these.

Just as an aside, I made a run of 4 EFI L20B manifolds last year, sold one to a member here and used one on a dyno mule later. Even at 450$-ish I only sold the one here, one locally, and one was kept for dyno testing. The last one is still sitting here waiting to be assembled and sold. Ratsun isn't the place to try and sell new parts, try over on the 510realm.


Dyno results? I didn't even know about these either
