4,7,10 mil cub?

Jay...

Any idea if that was a chassis dyno or a motor dyno?

 

Chassis dyno

I'm gonna say you can knock 10% of that dyno number. I'd also like to see a comparison on another dyno. (Not knocking your motor - it will still be a good runner; my 10 Mil Cub only makes 103-105 hp and it runs like a champ at the track.)

which curve is which?

which curve is which?

 

it wasnt a single wheel dyno and it had stock reeds and timing was +5 and with the porting that he already done and the other curve was with more porting vforce 3's and his rdz pipes and +7 or +8 port matched cases and a few more other lil things that my lil motor needed

So true....have u seen or heard of the cylinders wicked has come out with

 

Wicked New Cylinders

Hmm im missing something..i thought 68 mm was a 421 and a 66 was a 397??

Depends on stroke...

[banshee(911)]

Depends on stroke...

Right...it says 58mm +4 mm 421cc's

[Yamahopper10]

maybe all of their cylinders are 68mm bore, and the 58mm stands for + 4 longer stroke than stock.. so 58 stroke and 68 bore would be a 421.

Thanks for all the great input guys! I have talked to most of the site sponsers and decided to go with HJR. Hes putting together a ported 10 mil cub. now that i have a motor i need help picking a badass exhaust,intake, and carbs. Also cant decide if i should run gas or alky?

Kevin should be able to tell you what will work best with his motor.

[slobanshee]

methanol if you are strictly drag racing

[BigRed350x]

If you are going to be dune riding/racing I would skip the cub cylinder. Go with a serval or a twister cylinder. I'm partial to the twister stuff myself, but to each their own... Either way, I would go with the 10mil. Spend the money and get a good chassis setup. It will make a world of difference on the dunes & whoops. Whatever you decide to go with, I would send your cylinders off to Kevin at Herr Jugs Racing and get them ported. Or just buy them direct from him and have him port them before he sends them out.

Kevin did the porting/building already on the 10 mil cub already. lol He is who i bought everything from.l i wont be trail riding much with it. It will be playing a little then to the drags.
