General Buick Tech / Re: combustion chamber softening

I too wonder about the compression loss and how it would affect performance, the guy that I was talking to locally is a nitrous  guy he is planning to build a couple engines small blocks and apply this to them to see how it works for him he seemed pretty excited so I figured I would see if anyone had tried it on a Buick. 

Moonshine and nitrous lol

Thanks for the link Steve, I think the idea is to reduce quench area on motors with power adders like the hemi heads, what I have read is quench areas will work well if its tight the quote on the video was "knocking the carbon off" with the soften combustion chamber you have a larger tuning window without having to get the piston to head clearance very tight. I'm sure there are draw backs just doing some research to see if it been done for our application do our dished pistons have the same affect I wonder.

Hi guys been laying in the weeds not doing much with the car did some chassis and suspension work she rolls pretty straight and true now, we only had 1 test and tune event last year and 1 race this year with Covid restrictions.

I have a question about chamber softening to help reduce detonation, has anyone ever played with this or do you know of any that has?

I did not install the turbo so I’m not sure. Once I hear back on the test with the actuator off I will have to pull the downpipe and see hope it’s not that hate pulling apart a brand new turbo to port the exhaust.
I got the exact turbo on mine with an external gate I can get the boost down to 14psi.

Ok so far tested the can with air it seems to work as it should.
Looked at the fitting and casting of the turbo they seem good no blockage
A test with the actuator disconnected is in the works. 
This downpipe was on the old turbo worked well then.

I tried that Steve no change.
That was was what made me think there is no boost getting to the can
One thing I did not try but should have was unhook the actuator.

Car has had a new turbo 6262 added and a Lorenz controller TH style downpipe.
Puck moves freely and all hoses are new.
Installed a powerlogger for him and said I would help setup a decent tune in it.
Power logger and boost gauge both read the same
28-29 psi. (Car ran like a raped ape)
Cranked the boost controller back as far as I could no change.  Loosened the actuator 1/4 inch there was slack no change. Unhooked the boost controller went tuner style no change.
I might try a lighter can if I can find one local.
Boost pressure not getting to the can perhaps?
Any other ideas?
