Porting cyclinder heads lyc/cont

[406 JAMIE]

Hello all was wondering if anybody else has had porting work done to there heads?from what we have been reading it adds a xtra 5-6 hp per cyclinder this was done on a 540 AV.
. ty for ur time for reading.

Jamie were you guys able to support the 5HP per cylinder gain on a dyno? 6x5=30HP

If that's the case I think there would be a lot of interest. (if the price isn't way up there)

[406 JAMIE]

no sir not yet its what we we re reading about from a website we seen.thats what they said by there testing and findings.we r in the works of setting up a engine dyno flywheel power and i have been talking to my lil brother about it and maybe see what the future holds about aircraft hooked up to dyno lol.ty for ur reply brother besafe.

I have read a lot of posts from Dave at Watherthunder and he always states there is a lot more horsepower to be gained with our old antiquated Lycoming engines over the stock setups.
Keep us updated!!

I would guess maybe a 20-25hp gain overall if the person who does the work knows what they are doing otherwise I have seen more people who do not know what they are doing actually make their engine worse..

Don't polish the intake port to much.

Don't polish the intake port to much.

Your not supposed to Polish any intake port it will screw up your fuel delivery kinda like getting a bad piece of ass it will give you the drip.

can someone please PM me with more info on this like price and where to get this done at?

[John Fenner]

We used a flow bench to get best results on a mock cylinder, then matched all the rest to it, sad as hell with all of that plus many other mods, the engine was never truly wrung up, I even doubt the rings got broke in.

posting photos for 406 JAMIE

[406 JAMIE]

300$ each head/jugg.
We need both head and jug attached together to do the porting work.
Brother Jeff thank you sir for all your help with the pics your the man.

[John Fenner]

If you can, get a spot face to square up the port end of the guide, it would be beneficial to the next machinist to do the seat grinding, especially if he is a cheap hack like me using antique black and decker stems and stone holders

Any noticeable difference? Same prop and pitch before and after trials...?
