Removing flame arrestor
Has anyone removed the flame arrestor from their non IC ski? I don't know if the IC engines have the same thing. I know the inherrant danger to doing this but it doesn't seem that it doesn't do anything for air flow and i was thinking about getting rid of it. I know it seems desperate but i'm looking at every aspect of this engine.

the SCIC engines do not have that flame arrestor bc the stock manifold is acting as the flame arrestor.
you should have no problem at all removing it from your ski's manifold after you've installed an external interooler on the GTX SC.

shibbs, say that again? is there something in my non IC intake manifold?
I was under the presumption that you would mess with volume/area and the tune sort of speak if you did anything to the intake manifold???...PR...

the 155 and 185 4-tec engines have a metal mesh-like flame arrestor inside the intake manifold in that hollow space in the lower section. it's just a mesh sleeve, nothing crazy, hardly takes up any volume.
the 215 4-tecs have the stock intercooler in there instead acting as the flame arrestor.
so yes PR... there is "something" in every 4-tec manifold.... and IF we should mess with the intake manifold volume has yet to be determined, but it certainly makes sense to reduce that hollow volume which would increase pressure and increase air velocity thru the manifold.

Do you think the manifold is designed to work with the flame arrester better, than if you removed it it could create a turbulent air flow path??? I dunno???...PR...

if anything, the flame arrestor IS creating turbulance..... i don't have a positive answer for you PR as i was never in that situation with my RXT.
speak with red devil or two2currput and see if they have looked into this area on the GTX SCs.

Look what Les did with the intake here:

I'll try to post pictures from my manifold later since i have it off and handy.

Jerry i still don't understand how Les's intake manifold works.

He hacked it up to where it only consists of the runners. Then he fabed up some aluminum piece for the end of the runners and mounted the TB to that.
