Ok, I know I am going to get flamed for this.But I have searched and searched trying to find out what the difference is in the stock Puch cylinders.But I can not find any definate answer. I know 1-5 is aluminum, and 11,22, and 33 are High torque.Then there are the 1 and 2 Magnum cylinders. Then I have also heard that 8 fin cylinders are high torque.But I have seen #1-5 cylinders with 8 fins. I have even looked in the wiki but that wasnt much help either. Does anybody know for sure?

Re: Puch cylinder #s
aluminum cylinders have open transferports, hitorque has closed transfer ports. hi torque cylinders are cast iron. just my two cents
Re: Puch cylinder #s
Hi torque ones suck. super slow
Re: Puch cylinder #s
Bull shit. define slow. My puch with hitorque set up was running around 35 with a 15mm bing, closer to 30 with a 14mm. And will ACCELERATE up a hill till 25 and stay there.
oh, and this is at 3500' elevation.
don't tell me there slow

Re: Puch cylinder #s
the hi torque ones are so much better
Re: Puch cylinder #s
have you guys tried the other ones with the open transfers? just look at the difference in port size. They seem to rev way higher to me... Maybe you guys have different hi torque cylinders then mine I dunno. wanna see pics?
I didn't mean any disrespect I just meant to say that it seems to me that the non hi torque cylinder feels faster than the hi-torque cylinders that I have. The first two pics are intake ports and the second two are exhaust ports obviously. The three hi-torque cylinders I have all have different numbers on them but are otherwise the same according to my little slide rule. The one with bigger ports is the non hi-torque cylinder and is timed nearly the same as far as I can tell. It seems to wind out a little better... heres the transfers:
and as far as hi-torque goes, well I really don't know why they call them that. maybe cause the guy was high... :)
Re: Puch cylinder #s
High torque cylinders have closed transfers
Re: Puch cylinder #s
It is my understanding that smaller ports = higher torque and larger ports = higher revs in general
Re: Puch cylinder #s
they are called hi torque because the do produce alot more torque then the standard cyinders.
Re: Puch cylinder #s
Its my understanding that low revs = low power. I pull a bicycle trailer a lot with my ped and in my experience that across the board there is nothing more anything about the closed transfer/smaller port cylinder except maybe it seems a little quieter.
Re: Puch cylinder #s
I have used both an aluminum open port cylinder, and a hi-torque cast iron cylinder, and I can tell you without a doubt that the hi-torque accelerates WAY better than the aluminum, open transfer cylinder. Sure the aluminum cylinder had a higher top speed when both cylinders were untouched, but it took it SOOOO long to get there. I noticed the difference in the intake port size, and then matched the hi-torque cylinder's intake port size to the specs on the aluminum cylinder. Problem solved.
The aluminum cylinders are better for top speed if you don't want to do any work on the cylinders themselves, and don't care about acceleration. However, the hi-torque cylinders have the cast iron bore which allows easier port modification, and they accelerate better, so I stick my tongue out at you, Austin.
Re: Puch cylinder #s
well there ya have it... I was gonna try and port one of those hi-torque cylinders thats why I have couple extra but i went on ahead and bit the bullet for a tccd kit that I am very pleased with.. I was hoping somebody would give me a come back on this lol thanks
