[img]i/expressions/face-icon-small-smile.gif[/img] hello, i have a 350 shee on alky, I wonder how much hp it might have. i dont know anybody with a dyno,( probably coulnd afford it anyway). it has stock ign., ste drag pipes, 32 hv lectrons,15 cc coolhead(1000 ft. elev.),.020 weisco prolite,5 deg timing adv,reed cages gutted, cylnders ported but no duration changes just widen & gut ex. and open up intake and transfer runners real good,reed spacers, anybody got a rough idea how much power could(or could not) be there.

 

We could guess about it all day long, but no one can tell you for sure. I would guess in the 65hp range, depending on the porting. Hell, there are 350's out there making 85-90 hp, so I guess if the porting is setup for that, you could be up there.

Find a dyno and you tell us, also your builder should be able to give you a pretty good ballpark.

Just a couple of questions, why are you running alky and drag pipes on an engine that looks like it has been ported for MX?

If the ports durations hasnt been altered then it doesnt make sense to me to run your Shee on alky with drag pipes.

 

got the good race parts cheap after it was ported ,need to have the jugs reported but would rather find unported set to send to RESPECTABLE drag porter to port to the parts i've got, Probably A&S racing ?... (anybody got a set of uncut jugs 4 sale? )...for the time being I have to work with what ive got, can I raise ex. port to better match pipes ,without messin with transfers, or will that not work?[img]i/expressions/face-icon-small-smile.gif[/img]

 

The transfers are what really suck about banshee ports. THat is where a lot of time needs to be spent when porting.

How far are you from Paducah, KY? There is a shop over there with a dyno, which I am going to in the next month to dial my bike in. I can't remember the name of the shop, but I can try to find it for you.

 

What will make the engine last longer, alky, race gas, nitro?
All with a 30 HP shot of NOS

 

i live about 3 hrs from paduca, ...wonder what it cost to use a dyno? I hear there is one in louisville but I dont know where ...
