Torque at as many rpms as possible. I think you have the data already. Basically, the data to plot a nice torque curve.
I think putting it up with a 325 cfm carb and a header would be a typical 20r. The reason I'm interested in this is that my 20r has clearly different and more eager driving characteristics than my 22r. That head is really doing something despite the smaller 2.2 displacement, even bone stock.I know it's probably not possible to account for the better flow of the head but it would be fun to see what the smaller cubes and square bore/stroke relationship do to the numbers.
the 20R head and intake are greatly superior to the 22r as far as flow. ...
Hi blackdiamond,My Engine Analyzer software will plot graphs for you, however the range of RPM is limited in this version to 10 increments. I can send you one so you can see.If you want to plot a line graph is Excel, you can use the sheet with the 100>5000 torque numbers. You should be able to plot a graph with that data. I haven't played with Excel and graphing this data.Gnarls.
Y'all haven't mentioned it is possible to over gear for the tires you are running. By the way Gnarly, I'm happy to see you back. I remember reading the numbers you supplied for cams over on Pirate when looking for the best cam for me.
I started a new job this week and so far it has gotten my up earlier and kept me busy and I am still working to recover the house from last weekends camping trip so the end result me not having time or energy to mess with this yet. I would like to eventually.
Wow... that's interesting. It's less CCs?? The head is supposed to be better than the 22s?Gnarls.
Hey blackdiamond,Yeah.. I'm real familiar with time, work, house, no-energy, and chores. My little boy "Teddy Bear" wakes me up every morning about 3am. I don't get home from work until about 7:15pm. By 8:30pm I'm passed bushwacked, nearly brain-dead and moving at a Marlin dual-case 1st gear crawl speed. If you want to see torque/HP charts, I'll see what I can do with Excel's graphing feature after I work on the 20R data. I'm not an Excel expert, but I like to learn.Good luck with your new yob@!! Gnarls.
I would just need a table with rpm and torque to get me started.
I am convinced the 20r is better than the 22r as far as drivability goes. Much more rev happy and feels like a better torque curve all around. I'm sure it's the head design.
That's really fun, thanks! That's what it feels like too. It "ramps up" torque faster than my 22r and pulls harder, longer. Must be the "square" bore and stroke design. I can't wait to see the numbers when you throw some cams at it.
I didn't know there was 85.5 octane gas? The compression number I found for the 20R is 8.5? The compression ratio for the 22R is 9.0:1?? I guess the lower compression of the 20R runs on the lower octane fuel.Gnarls.
85 is considered regular grade in Colorado where the elevation is higher.
Great info,after all the reading,I'm going to replace my cam.I'm running 5:71and 5speed with 20r,on 35's,runs great off road,falls on it's face at freeway speed.From rpm charts,my set up is real close to same rpms as stock gears tires and 4 speed.
I like the headers with the stock cam.............
I finally managed to get my dyno program to work.these specs are what I had written down in my old LCE catalog
