    Default Dyno day friday

    Going to do some tuning and plan on bringing some plugs, jets, air bleeds. Anything else you guys usually mess with on an engine dyno? I also have some royal purple oil I thought I'd throw in for a pull or two torwards the end.

    Hoping for 600+ on my little 347 sbf. Got some Q16 to try out also.

    You should be right there. Nice build. Be interesting to see if it needs the spacer or not.

    Have fun, What headers are you using ?

    Before the Q-16 what fuel are you using ? and what oil before the Royal Purple.. the syn should be worth 8 hp +/- 2

    Hopefully my headers will fit on their dyno which are Accufab 1 3/4 LT's. Theirs are some crappy street rod 1 5/8 headers which will kill power I think.

    The other fuel is Trick Racing 110 or some VP 110. Probably the Trick since I have it.

    Oil will be Valvoline VR1 to start with, then do a few pulls with the other. Not worried about break in, the rotating assembly is the same as before, just did the head work, cam, intake and vacuum pump. About a point more compression from milling the heads too. Did 532hp last time out thru those street rod headers.

    Well, made right at what I thought. Wish I could of used my headers but still made the numbers.

    605hp at 7600 and 460tq, and sounds nasty. :P
    Picked up about 15 hp on the Q16.

    Good job. That's a stout little piece.

    Default peak torque etc.

    I was under the impression that peak torque was limited to 5252 RPM or something similar do the limitations of a circle etc. etc. I'm just an interested greenhorn trying to learn as much as I can.

    HP and TQ are always equal @ 5252 (or damn close to there, have to look to be sure). TQ is an actual measurement, HP is a math equation using RPM, and TQ.

    As stated it can (pk trq) be above 5,252 rpm. Both hp and trq just cross the line at that rpm. My peak trq was at 6,000 pk power at 7,000.





    I posted my sheet so you can see what the curve looks like, not to take away from the accomplishment of that little 347..... that thing is a mean little bastard at 1.74 hp per cu/in it kicks my Big Blocks ass at 1.65 hp/cu.in. My engine would make 985 with that number.
