Desk top dyno guys
If somebody has the time, i have my new engine all drawn up on paper and was wandering what it might produce. Here are the stats, let me know if i'm missing something.
Flat top pistons 3.5cc valve recess
75cc combustion chamber
Smog style heads(the heavy duty ones from a truck, don't have the # handy but it's not the 882's)
2.02 /1.6 valves
bore 4.04
stroke 3.75
head gasket .015 with a 4.1 bore
Compression is 10.5:1
preforer dual plane intake
Barry grant 750 carb
comp cam 270
dynomax headers 3" collector
4" side pipes with jcl baffles
thanks

Re: Desk top dyno guys (honaker)
I don't have a Desktop Dyno but your setup sounds to me like a 390 - 420 HP engine with more potential. If the heads are Stage II ported and you would run a more radical cam + a Performer RPM cam you could easyly get to 450.
The Performer is a low RPM intake (up to 5500) If you want to make big HP you need RPM and a performer just doesn't perform good above 5500
:cheers:

Re: Desk top dyno guys (SuperFast80)
Peak horsepower - 334 @ 4500rpm
Torque - 435 @ 2000 RPM
The torque curve is nice and flat up to 3500 rpm.
I had to guess at some of the cam specs, such as lift and centerline. This engine might possibly make more power, but these figures give a good indication of what it will do.
