2 stroke vs 4 stroke turbo torque comparisons

[snowmanx]

Debating whether my next sled should be a M sled(probably 1000) turbo, VS a 4 stroke turbo(nytro or doo).

I threw my leg over a Nytro at about 13# of boost, vs a 09 1000M at about 10#, and I REALLY liked the power of the 4 banger. It just felt sooooo different(first time on any 4 stroke, esp turbo). I'm riding a cat 900 turbo at 12# right now, and supposedly about 240 HP, and the Nytro, at 13#, about 240-250? BUT, it felt like the nytro had so much more power than my 900, and the 1000 that I rode. Is this because of the torque curve?

Been doing a little research, and came across MCX dyno on a 1200 doo......torque was about 190#-210# from 6200-8300 RPM!!!!! http://www.mcx.se/ That's amazing! (to me any way).

Can't recall, but I vaguely remember seeing a 2 stroke turbo dyno and the torque was about 145????? and we all know how the torque curve looked, pretty peaky compared to the 4 banger.

Anyways, anyone who wants to chime in, I'd like to learn more. Thanks.....and I'm starting to lean towards the 4 stroke. I know, I know, I'm a slow learner! LOL

Torque as a comparison between two engines is tough.

lower rpm engines will be making much more torque for the same HP value as a higher rpm engine.

that being said, your 900 is making about 200-210 at 12 pounds boost, you would need 18-20 to make 240 . case reed turbos need huge compressors to make the math work all the way through.


the wider rpm spread of the 4 cylinder 4 stroke feels good though,, and is much more tractable and lees likely to dig straight down before moving forward..LOL wheelie king..!!!

As far as a drag race wit TRACTION, the 2 stroke will beat it with less power due to weight and torque.


have fun

A 2 stroke turbo will never beat a 4. Ever. There is no comparison i power between the 2
