CPI "LIGER" Cylinder project
Pete said I should be around 200 exhaust 130 transfers
but he had some markings of 197 and 130 so maybe the exhaust turned out a little less than he thought.
I was shooting for 198exh - 128 transfers once I get some time and pull the motor and start mocking up maybe I will acheive those numbers.
As for the numbers out the box for the cylinder I would guess lower 190's but thats just guessing.
Calvin should be able to answer this for you.

i bet it'd make more than 800. twin-cylinder cr500 engines i have seen make about 200, whereas one only makes around 60-65. you get more cylinders working together, the power increases exponentially. i bet 1000HP would be a low estimate, considering these cylinders are projected to perform like the sabertooth, at 100HP per single hole.......
god that would be a bad ass vehicle to ride around in.....but your fuel consumption would be figured in gallons per mile LOL

altho they never posted a better picture, theres a vid of a bike linked on the other site and several pictures, looks kickass, i'm building one no question

maybe. but when a twin cylinder banshee under 500cc can make 120+hp fairly easily, why is it unreasonable for a twin 1000cc to easily make over 200?100hp honda wrote:trick racing was a hoax pic. been floating around for years
i remember a 4 cylinder banshee motor that had been built and dyno'd, at around 125HP per hole off the bottle.......so imagine a v-8 Liger motor

if the single cylinder makes a projected 100 ish, then 800 would be a bare minumim, but if done properly, adding more cylinders exponentially increases the power produced.

thats why a tripple sled with lower port timing and way older technology will still pump out significantly more power than the new high strung EFI twins
XCR 800=162 horse bone stock pipe, reeds, carb and its in the 180s and still will go WFO for minutes on end all day... for a few years
twins can get 160... with a lot of work
the 450 will have less power and will be harder to start, and will be heavier, but to make up for it it will require more maintenance.

um just put a RS250 motor in it? or better yet, 2 RS250's joined together... basically, if you can dream it up, someone has already done it...2strokeforever wrote:if you could fit the pipes of a rs 250 road racer on a bike thad be sweettwin cr125 would kick ass
o and give it the same port time area as a 125

Kenny Roberts engine
I seen the Kenny Roberts bike at Carnegie in the beginning of October at the races the engine sounded wicked people thought it was some snowmobile engine, the bike it self was bad ass to although it was set up to long and just fried the big tera flex tire to about 200 ft that may have been it's first run I'm not sure

Please explain to me how engines making 60hp each when combined suddenly make 200hp total.NightBiker07 wrote:rsss396 wrote:that would a 5 litre fire breathing dragon making 800+ hp and only weighing a couple hundred poundsjimmy_cr500 wrote:that is so cool. i dream of one day building a V8 out of 8 ligers, and running it in an old hot rod. imagine 4 expansion chamber snaking out of each side of the engine bay... and the noise it would make!

arctic cat m1000 snowmobilePlease explain to me how engines making 60hp each when combined suddenly make 200hp total.
so bump the port time up so it peaks around 8500 and youll have your 200 horseThe proven 999cc power plant is a good motor and remains unchained for 2010. the 90.3 x 70 bore and stroke twin-cylinder two-stroke mill delivers 162 HP at 7,250 – 7,300 rpm, and a whopping 116-to 118-foot-pounds of torque.
i think a 500 peak torque is at 6700rpm ish
the 450 will have less power and will be harder to start, and will be heavier, but to make up for it it will require more maintenance.
