flowbench data

[dohcfiend]

any1 have flowbench data from a set of stock 96-97 heads? being how it might be counter-productive to build a 3.4 dohc for high rpm if the heads choke at 7k(hypethetically)

if any1 does could they plz pm, email or post it?

Those aren't correct.

Bone stock they flowed max 270/178, and that was on a early set. you have something screwed up.

but flow numberss dont matter anyway, right?

anyone that knows anything about head porting can tell you, flow numbers don't mean shit

[dohcfiend]

desktop dyno? i was referring to real flowbench data. isn't there also a way they can determine cfm at a certain rpm too, even though the heads are off the engine or is it just a mathmatical formula?

if it is care to share?

I'm also curious about ACTUAL FLOWBENCH INFO for both early and late heads as well.

[donk_316]

Well DKOV is sitting with the info and he posted a "screen shot" of a flow chart. It would be innacurate to try and figure out what it says from that though. Nice if he could post some numbers since he has it.

[Will'sFiero]

Not like posting stock numbers is going to cost him anything...

[donk_316]

If it does truly flow 270 / 178 id be happy with that. ive been using the numbers i posted above for everything i have been doing.

[Doubt_Incarnate]

i think even dd2k files for 3100's have higher numbers than that

[donk_316]

Well those numbers are taken out of the DOHC DD2000 file on this site.

[dohcfiend]

actually a chart is up on here for the pre-96 heads. it is a thread started by dmmotorsports i think.

[donk_316]

I have made a flow file based of the screen shot of DKOV flow data. Its as accurate as its gonna get.

Email me and ill give it to you or add me to your MSNM
