What is the difference between 11:1 and 12:1 powerwise or any other differences? Thanks

 

11:1 you can use premium and some octane boost, 12:1 you need race gas, so there will be a difference, i would estimate prolly a few ponies power wise. 3 maybee 4, but i am just guessing on the ponie number.

 

i picked up 2 bikes from a 11:1 TO A 12:1 PISTON, AND NOW IM ON RACE GAS.

 

You may pick up a horse going from 11/1 too 12/1. But thats a horse across the power curve....[img]i/expressions/face-icon-small-smile.gif[/img]. Not worth the trouble of running down race gas around here.

 

That seems like a nice increase to me. Is that up Olds or in a certain distance?

Surely there is some % of hp gained per point of compression increased ratio, who knows it?

 

I just rode a 11:1 tonight at the Craycraft stables. It was certainly fast but didn't have the same arm-stretching torque as my 12:1 with pretty much the same mods. I'm geared a lot higher, 12/40 with 18" rear tires, than Bob's machine and I'm sure that had something to do with the different feel but I think the higher compression gives a bit more ooomph.

 

what about 11:1 102mm vs. 11:1 105mm, whats the difference there, would it be a 727 or what?

 

Good ? I need to know for my Z400. I know that you have more low end power with higher compression. But how much?

 

You don't need race gas @ 12:1.

 

The diffrence i got was the same bike i raced on halloween i beat him by 3 bike instead of one now that i am on the 12:1....

I like the diffrence alot could tell....
