hey hey,

you mentioned before that you were using performance trends software, can you theoretically calculate bhp and torque figures from that software using different lift and flow profiles?? :rolleyes:

i did try sending a PM a while back, but i don't know if you got it??

Cheers

you can.... I play around with backpressure and stuff. On the whole I don't think it's very good with overlap and backpressure, I'm lead to believe that it takes a very good simulator to get close to reality during that part of the cycle. I've ended up trying to look at how sensitive a particular cam is to backpressure to decide how suitable it is.

if i give you some different flow figures and lift, like standard against piper, would you be able to punch it in and get some screen shots for me?

i've got my project assignment due in, ricardo and GT power, are way to advanced to get any sort of figures from.... pretty much a years worth of work on theyre own sadly :disagree:

you can download and use it free for a month, you may as well try doing it for yourself, it's pretty easy to use.

ah sweet, i didn't realise that..... first thing i saw was the dollar signs lol :cool:

One other thing, is there any way to calculate CFM , from the flow percentage and the ranges used?? :crap:

supaflow should be able to tell you that, have you looked on their web site?

i'll have a look tonight, and see if i can make anything out..... the superflow book i have is ancient... its confusing me... what are inches?? :laugh: haha

Just flowed my ports in CFD have done my calcs from the data yet tho:

Hi mate,

I've installed the demo, i'm having some trouble...

i haven't got any CFM rating for the intercooler, and the rocker ratio??

when i run the simulation, it says A/F mixture very poor... any ideas? i can't find anything on A/F ratios?? :confused:
