You should place this next to the books and references post so it can be accessed easily.

comp cams is now offering a free cam sellection software,THIS IS A USEFUL TOOL, this is useful in seeing the lift/duration/LCA they suggest for your application, in most cases they get fairly close so its a tool thats useful, now you don,t necessarily need to buy a COMP CAM but a cam with a similar lift/duration/LCA from your favorite manufacturer probably should be fairly close to whats recommended

"HEY GRUMPYVETTE!,Interesting that it says going to a single plane wouldn't hurt my tq. curve it would also raise my peak tq. by 20 and give me 40 hp."


software simulations are only as good as the data paramiters used, and its RARE for a single plane to best a good dual plane intake below about 5500rpm, in tq or hp so keep that in mind!

your looking to increase the AVERAGE hp/tq more than the PEAK hp/tq if you want a fast car!
Ive seen a 20hp gain in PEAK hp on a 496 BBC resulting from a single plane intake swap from a good dual plane intake slow the cars 1/4 mile times over two tenths of a second, your gearing, suspension, traction,power to weight ratio and AVERAGE RPM band has a huge effect on the TOTAL performance.
the only way youll know if the software guess is correct is TESTING the parts on YOUR particular combo,in the real world

BTW
this software

http://www.auto-ware.com/software/eap/eap.htm

is a P.I.T.A. to use but its is usually far closer to correct, and when you make a bad choice in components it points out the flaws and suggests where you can improve the combo

Hey Grumpyvette the link to my gear calculators doesn't seem to be working. It should be:

http://purplesagetradingp ost.com/sumner/bvillecar/...

Thanks for including it and hope they help some of the guys here. If you want to fix the link and delete this that is fine or leave this post.

Thanks for all that you are doing for us,

Sum
