The end all be all cam thread.........

[Stan Weiss]

what about the FRPP 4V cams? i have the "ford gt" high lift cam set. i dont even know the specs on them.. i wonder how they compare to the FR500 high lift kit with the springs and valves? and compared to all the aftermarket brands?

good posting though! thanks for taking the time and puting that together

I think you mean VT Stage 1 N/A . I would change it but for some reason I no longer have an "EDIT" button on that post.

New forum rules...your only allowed X amount of time to edit posts....its to keep people from going back and editing out posts that have gotten them banned.

I dont like it at all, but what cha going to do...I already voiced my opinion about it to an admin..to no avail Its times like these when editing old posts would be very nice and handy.

We really need to try and add some intake lobe centerline (ILC), without this all those numbers don't really tell you much. The only one that has it is the stage 2 blower cams by CMS (with +4) which means advance which means the ICL is 108.
If you have this I can tell you seat open and closing time for intake and exhaust, i can tell you cam advance, i can tell you overlap.

For example. For a PD blower you want very little to 0 overlap, but you also want little advance as well (or lower ILC which means later intake closing ) in order to keep a lower dynamic compression to keep heat down starting in the low rpm's.
With ILC i can tell you that my VT stage 1 N/A cams have -1 cam advance comapred to my blower cams of +4, a slightly later intake valve seat of 42.5 vs my blower cams of 41 degrees. So what does this mean? If i ran my N/A cams with boost my dynamic compression would be much lower and keep heat down, but also the ILC tells me my overlap with the N/A cams is 6 degrees vs .5 of my blower cams (stage 2.5's have 0) so while the low advance/late seating of my intake valve (and wide overlap) with my N/A cams would reduce compression from not closing the valve at BDC (which would make compression much higher) it's overlap would cause me a good deal loss in power and rate of boost increase.

On a SOHC engine if I know intake duration, exhaust duration, and LSA that I can calculate overlap.
Crower cams 62810-2 248I 262E 114LSA
ICL 114 10-58I 65-17E Overlap 27
ICL 106 18-50I 73-9E Overlap 27 (Adavnced 8 Degrees)

For example. For a PD blower you want very little to 0 overlap, but you also want little advance as well (or lower ILC which means later intake closing ) in order to keep a lower dynamic compression to keep heat down starting in the low rpm's.

While IVC closing does control dynamic CR, can you please show me a cam which closes the intake valve at BDC?

If a engine has 10.0:1 CR with the above cam it will have 8.353 DCR ICL 114 if the cam is advanced 8 degrees ICL 106 it will have 8.774 DCR. If the intake valve closed at BDC DCR would equal CR.

Anyone know the specs on the afm f-42s?

Pretty mild blower cam that I just purchased though have seen claims of 50 horsepower with only 8 psi.

lunati now makes mod motor cams, i will add them when I get a chance

added the lunati cams

 

[rconaway]

I just had Livernois do the heads along with their Stage 1 Cams on my GT and hit 643rwhp with the fuel system not updated enough to handle and tuning not completed so I'm kind of partial to those cams personally. However, I think it has a lot to do with the heads obviously.
