Re: exhaust i was working on today
 

no. they only turbo airplanes for high altitude flying. i really dont know why they dont use turbos to make more power though. that is the complete exhaust on the plane. that exhaust adds quite a bit of power. airplanes make power a lot different than cars. they want zero back pressure and only rev to 2700 rpm. that plane makes about 310hp at 2700rpm, its also a 540 cu.in. 6 cylinder

my truck makes 120hp at 3200, with 300 cubic 6. almost there!!

Re: exhaust i was working on today
 

I guess you would want lots of torque lol. Thats a fucken big engine.

Re: exhaust i was working on today
 

yea. i have a piston, cylinder and valves. ill take a pic to show how big it all is later today

Re: exhaust i was working on today
 

looks good

Re: exhaust i was working on today
 

Before anyone yips about how little power it makes for the displacement, everyone has to remember that aircraft engines, like marine engines, are designed to operate at heavy loads for an extended time....so for the same displacement as an automotive engine you get less power due to more conservative tune. A lot of marine engines run 1 degree ATDC total timing.

Re: exhaust i was working on today
 

these engines run at 25 degrees btdc. they also only rev to 2700rpm, so 300hp at 2700 rpm is way better than any stock car engine

Re: exhaust i was working on today
 

nice, must be fun being around planes.

Re: exhaust i was working on today
 

yea, its pretty cool. i just wish i could fly more
