PC engine dyno
Hey, So I got out of work early today and started to lplay with some engine dyno software for the PC. This thing is awsome, every measurement. setting and options are in it and it seems to be only about 2hp off. I ran a stock 2.5 944 with a supercharger setup like Speed force racing and the numbers are just about right on give or take 3-4hp. So then I was like cool, lets try my setup and add a WEB CAm grind 274 and a Light weight flywheel and a 75hp shot of nitrous with a progressive controler starting at 2000rpm with a 10% shot and the full 75 from 4,000 on to 6500. (This is my project for spring) I came up with approx 243hp @5,000 RPM and 289 FT/tq @ 4,000 RPM. My numbers where a little higher on the first test but I had to pull some timming out due to possable knock. Also the cam has a little to much overlap making me loose some fresh A/F mix. I still gotta play a little bit. Anyway now all I gotta do is get it done and see how close I can get the real thing to it, It would be sweet to have those numbers for my NA guess we will find out. If anyone is intrested check it out

Check out The Road Dyno I know a couple people that have used them to tune 500hp+ Corvettes and a 944SC with great success.

Well they had Almost all the info for a stock 1985 844 in the library on the program, SO I used those, Made some changes for my MAF and exhaust changes, added in the WEB cam grrind which was also on file, The only thing Im not sure of is the spark timming on the FR-wilk power prom 2 so I added my own spark timming curve. Then I just setup the nitrous
