Torque Banshee


Recommended Posts

I'm in the process of building a Banshee from the frame up. I'm not at all worried about horsepower numbers, what I want is torque. All that will be done to the motor is stock bore and stroke with Wiseco's, cool head with 22cc domes, Toomey T-5 complete system, Toomey filter, stock carbs tuned for filter and pipes, I think that's about it... What I wanna know is what are the best choices for replacement reeds for bottom end torque and what can I do to get more bottom end out of my combination? I'm planning on heavy trail riding so again, horsepower numbers are useless to me, I need torque. I know that I won't get much torque out of a 2-stroke but I'd like to be able to get as much as possible...

Ya I was planning on porting or at least smoothing things out and profiling a bit. I don't wanna go in and hog them out first thing, I'd rather let a professional shop do the major porting. I'd planned on VF3's but just in case i have to use the stock reed cages what are the best replacement reeds? The domes, what size would be best? It's a Top Notch Billet cool head so I'm not even sure if it has the same dome design as the more popular brands. And call me stupid but what are the pt lows you're talking about? This is my first Banshee and only my second 2 stroke so I'm gonna act stupid so I can get everything explained as detailed as I can.

That sounds awesome but that's kinda what I'm limited to, fundage. I'm trying to take what I already have and work with it as much as possible. Bore, stroke, etc. are things that are pretty much gonna be a given, no changing them. If I had plenty of money I'd go with a 421 powervalve motor that way I wouldn't have to worry bout lack of power but for right now I'm stuck with what I've got.

Well then the next step then is to list what your looking to spend..

 

RIPPEN

 

I'm looking to spend as little as possible. And trust me, I know that's not possible lol. But seriously, right now I just wanna get it on the trail. I would be satisfied with putting the stock stuff back on it but with past experiences everyone is always looking for more bottom end. That's what I wanna get out of mine. I'm looking to use the stock airbox and as much stock stuff as I can for cost effectiveness right now. I want to keep it simple for reliability. I haven't even started on the motor yet so any suggestions whatsoever are appreciated...

This is what is done to my bike, and it makes a ton of torque and mid power.

 

Dynoport 2 into 1 pipe with ultra quiet silencer.

Dynoport Port job.(yes dynoport does port work for the 2 into 1 pipe).

2 into 1 trinity intake with 35mm pwk and K&N pod filter (you may want to run an airbox though)

Stock reed cages with carbon tech low-mid reeds.

Flywheel lightened. (rs heavier magnet flywheel).

Cascade Heavy duty clutch kit.

+6 timing advanced.

Pro design head with 19cc domes on 50/50 race gas (169 psi comp).

13/46 gearing.

Wiseco Pro lite pistons.

 

 

Its a real strong running bike, amazes a lot of people, and its easy to keep on the pipe at slow speeds.

because money is an object, i would say that race gas would be what limits how far you go more than the bottom end.

i have heard than 150 psi and +4 timing is about as far as you can go on pump gas.

For the money, I would sell the t-5's and use Paul turners and call it a day. The difference in low end from a toomey to a turner is not even comparable. Paul turners hit the pipe almost immediately. I cant even ride with those damn things there so torqy.

Ok I'm running stock crank and rods, how many cc's lower can I go and not hurt the bottom end?

 

I used to run a 20cc dome at 155 psi compression on 92 octane, had zero issues with it. Now I run a 19cc dome at 169 psi on 50/50 race gas and it works great still.

Ok, good info on the Paul Turner's and the domes. What about Pro Circuits? Almost snagged a set the other nite. They were cheap enough I figured I could at least try them out but ended up losing the bid... DG's? FMF's? And I may run race fuel anyhow. To look inside of a motor that has been ran on today's pump gas is sickening, so much oil in it that it's a wonder an engine even fires with it and it also causes horrible build up from the fuel. Anyway... Keep the info pouring in!!!

Weird, I had my motor apart after about 40 hours to replace the pistons and have dynoport do the port work. On 92 octane pump gas the piston domes had little to no carbon and everything looked real clean and new.

 

Pro Circuits make power to about 8500rpm, Dynoport 2 into 1 with dynoport porting make power to about 9,000 rpm. Still waiting on my dyno guy to send me the ptr rpm numbers.
