What did the stock TPI throttle bodys flow ,cfm wise? Im trying to type in a combination on my desk top dyno.

 

I'm not sure,but I used 650cfm.

 

The stock TB flows around 675 cfm depending on whose measuring, but that's not the # you want to enter into Desktop Dyno. It's really looking for the flow capactiy of the whole intake system from the airbox to the manifold exit at a pressure drop of 1.5 in-HG. That's a much lower number. I'm using 500 CFM to represent a high flow airbox, K&N filter, ported MAF, stock TB w/ airfoil, ported plenum, cleaned up stock runners, and stock base.

 

Thanks for the help!

 

I heard when using the desk top dyno you have to type in the factory roller cam as a hydralic cam ,is this true ? Keep in mind I dont have desk top dyno 2000 I have the regular version which dosnt have factory rollers as an option.
And I need the adv. duration for the 89 TPI 350 all I can find on this site is the .050 duration ,thanks again.
