Turbo or supercharged 2Ts?

[Yow Ling]

the other way to look at it is a 100 4 stroke is a f5 bike , with a turbo its a f4 bike , maybe should be the same been the 2 stroke been 50 cc ?

plus that gets rid of the carburetion equivalent part of the 125 stuff 15mm carb would just about kill it

[F5 Dave]

Yhe current 2/3 for a turbo rule isn't adequate if someone made a decent job of it, just no one has. The double cc rule for F5 isn't just either as we've seen carb restrictions are not that effective, its just that someone was thinking shitty old CB100, yeah that'd be right.

Yes, and the air cooled part confuses it too ... 2/3 of 100cc water cooled ?? and/or 2/3 of 125 aircooled.

[speedpro]

I am not sure what a sensible size is either, but the way I figured it, the supercharged 4T limit of 100cc is 2/3rds the normally aspirated 4T. So 2/3rds of 125 is 82.5, but there is talk of MX85's so I chose a 70cc limit for 2T forced induction.

70cc for 2T forced induction? would that seem sensible....

The forced induction limit of 100cc was created when the capacity limit for F4 was 125cc(4T)

[F5 Dave]

Yeah it was pretty silly then, but I guess they were thinking Victor motor driven onto a C90.

Good point that man

Back in the day the rule was 100cc fourstroke, open, no restrictions. Don't change that rule, as has been said earlier there are a few 100cc supercharge projects under way, would be a pitty to see these projects die before they raced.
Dave before you answer, remember, you will be riding this SC twin bucket to fame and glory. Got your vote then?

I suspect that if you can guarantee it will last longer than 15min on Ruapuna B track, the answer is yes...

Back in the day it was also open fuel for the blown 100's - which helped a LOT.

In the Buckets class?????

Maybe I'll ride it, after all I'm getting a new hip shortly. Told my wife I'll be 17 again, with a mature 53 year olds brain. She says more likely 53, with a 17 year olds brain. Probably closer to the truth.

Yes open, methanol fuel with a hint of nitro, (say 50%), 14lbs boost, approx 18,000 rpm. Weigh a ton and have a short fuse I would imagine. More parts turning up on saturday for this project.

Who am I kidding, I can't ride a bucket any more.

Potentially Less fraught than telling her that you'd like to ride a 17 year old.

I just finally got that......ya bugger.... hopefully I get my braces off in a few weeks.........
The girl was a bit dim......I still would (of course),but id feel a little guilty afterwards though.
