I have the desktop dyno 2000 on my computer. I entered some info about my car (96 SS). I put in ported stock heads, high performance exhaust, and my aftermarket cam specs. This combo made approximately 390 - 400 hp and 350-360 ft. lbs. of torque. I then entered the same info, but switched the cam info to my stock cam and the horsepower dropped a little, but torque was well over 400. Would this be correct?
Thanks.

 

its the right idea. torque doesnt increase as it should when larger cams are matched with ported heads...

 

So would I be better off to leave the stock cam in?

 

not necessarily. that program isnt completely accurate.

 

Make sure you read the instructions that came with your dyno prog. On mine, if a roller cam has less than 240 degrees, you enter it as a hydraulic lifter flat tappet cam. The numbers are then much more accurate.

 

Hey nasty...Can you send me the fine I think it would be a .dyn file ...
Did you put in the flow numbers of your heads????
what did you set the induction at??

 

I did not put in the flow numbers from my heads. I have not had them worked on yet, but I entered Low performance, pocket ported on the program. I set the induction at 750 cfm. I figured this might be comparable to a 58 mm throttle body.

 

Send me your email addy...I will send you the flow file for LLoyds heads...and see what kinda diff it makes...BTW.... THE 58MM IS GOOD FOR 1300 CFM AND AT GOOD CAI is good for at least 800 cfm and if you get a bigger filter on one its more.....the 800 Number is for the lil bitty filter they send with it.....
