CamQuest

Has any one used ths program when building a motor? i found it on the comp cam website and can not stop playing with it!

I am wondering how accurate it really is and how accurate their flow bench numbers are for the different heads in the database.

 

no one on here has used this program?. its free to download and fun as hell to play with.

 

It's a VERY stripped version of Desktop Dyno & DynoSim.

As a general rule, the more information you personally put into a program, the more accurate it is. The programs all make assumptions that may not work in the real world; the low-end programs make more assumptions, if that makes sense. Most of them assume ideal mixture distribution, no detonation, ideal timng, excellent ring seal, etc. They also tend to assume higher volumetric efficiencies than actually occur. As a result....

Dedicated racing engines tend to be reasonably close to the good programs' output, often within 5%, sometimes closer. Street engines are often 10% off or more, always to the "down" side of the program's results. This probably occurs because of racing engines (hopefully) having higher VEs (overall as well as peak) and specific flow figures available.

If you have accurate flow numbers for your cylinder heads, CamQuest may do OK. The preset program numbers for heads and manifolds tend to be very optimistic.

All of these programs are reasonably good for making comparisons and giving you an idea what will happen with different parts...in other words, kinda like a real engine dyno.

 

the head numbers seem pretty close to some of the heads i've been looking at....it gave me some pretty big numbers on my 301 combo....and real low on my centrifigal blown 383 combo...might try some others for kicks ....pretty interesting.... thanks

 

Yea, I've got it too. However, I'm not sure if it's just my install, but if I re-load a saved engine combo and try to change a spec. the program instantly crashes and disappears. Does that happen to anybody else's?

 

I've also got it and the numbers sometimes seem pretty high to me especially since my motor isn't full of crazy parts but it tells me that with what i have i should be kicking out 450 to 475 horse outta my 40 over 283 with a tunnel ram 2 600 holley's and a big mutha thumper hydraulic cam and a set of 58cc chamber heads that have only been cleaned up and bigger springs.

 

i think the coolest part is that your can look at the tourqe curves of each cam. and see how low the tourqe comes in and how long it stays.
