Desk top dyno help
Was wondering if any one out there that had a desk top dyno could plug my info in and tell me aprox. H.P and Torque figures. If so here is the info: Thanks in advance
351W stroked to 408 Block decked to 9.480 align honed squared bored .030 over and torqe plated Scatt Crank 4.0 stroke, rotating assembly balanced Scatt H beam rods 6.25 Alum. 1.6 roller rockers World product Alum. heads 2.02x1.6, 64cc chamber and 197cc runner JE -19cc pistons, 10.1 compression Comp Cams 240-260 duration 541-544 lift @.050 Canton road race pan girdle and windage tray Deamon 650 at this time but will probably go to a 750 when funds allow. Any other info needed?????? |
I'll do it for you dlowe.....that's a really long rod you're using...does that thing like to rev?
I'm using a 4.100 stroke and a 6.200 rod....it makes every bit of its power at 5400..... Anyway, give me a few minutes... |
Hey.....is that the advertised or actual duration on that cam? Seems kinda high for the lift....I'll see if I can find it in the Comp Cams catalog.....
|
Oh....one more thing....need to know if you have a single or dual plane intake....if you don't respond here in the next few, I'll just do it with both.
|
OK....
The cam grind I came up with was a hydraulic flat tappet, 35-250-4, 240 and 246 degrees duration, .541", .544" lift, 110 degree lobe separation. With a single plane and a 650cfm carb, 434hp @ 6000, 431lb-ft at 4500. With a single plane and a 750cfm carb, 442hp @ 6000, 434lb-ft at 4500. With a dual plane and a 650cfm carb, 403hp @ 5500, 417lb-ft at 4500. With a dual plane and a 750cfm carb, 409hp @ 5500, 421lb-ft at 4500. Desktop Dyno is pretty good on being right with the horsepower numbers....sometimes the torque is off a little though. When I did my engine, I came up with 490hp...it dyno'd at 484. :) |
