    That's old school, believe it or not, but still shows the detail that goes into a PS engine. Larry Widmere (The Old One) built a PS TBird, correct to NHRA specs, and took it to the drag strip one race, with the sanctioning body there, and ran over 200mph in the 1/4 years before anyone else did...just to prove a point.
    His anachronym for RPM...ruin people's motors...
    The PS engine in that write up, if I'm not mistaken, is actually two different engines.
    Amazingly sharp man. I've read everything of his I can get my hands on.

    seems like he left the scene about as fast as he appeared. What the hell ever happened to him. He was in another world when it cam to heads and airflow. Could put more compression in a motor and run it leaner than hell and never detonate the thing.

    Larry's still around. He's got (had the whole time) a company called ENDYN, and they are focused on Hondas, Toyotas and a few other imports.

    Scott,

    Do you have any idea what the cylinder pressures are ? The individual cylinder timing is interesting. 11-13 degrees BTDC did I read that right ?

    I'd have to go back and see if I have anything in my notes, but I don't remember what cyl pressures on a PS engine were. (This was 18yrs ago for me) AFA the timing, you have to understand what Larry Widmere was all about. He developed the "soft head" technology that put both Glidden and Bill Elliot so far ahead of the competition at that time. It was all about chamber effeciency, and building a piston dome/chamber relationship that put that "sweet spot" of compressed air/fuel exactly where they wanted it. With chamber effeciency that good, you don't need as much lead, and with so little lead, you can extend the peak cyl pressure to the area he was referring to (20* - 30*atdc). Individual cyl timing isn't anything new. Cup cars have been doing it for years, but without cyl pressure data, it's kind of a waste.
