FMS F13 vs TR224 dyno results inside Got the car back on the dyno yesterday after installing the F13 cam and SVO 30# injectors. Surprisingly, the initial tune was very close. Only needed a minor tweak in fuel.
Cam spec's are 230/232.7 .596"/.585" 113+4 (I actually installed it 2 degrees retarded though so it's on a 111 icl)
My old numbers with the TR224/114 cam were 415 rwhp / 404 rwtq. I changed the cam, injectors and went from a 2-1/2" ORY to a 3" ORY since then.
New SAE corrected numbers: 439 rwhp / 404 rwtq
This is in full street trim, exactly how I drive it every day (all belts, air filter, 18x10 wheels, 12 bolt, full exhaust, etc).
The thing I'm impressed with the most is that this cam is not that much bigger, it has a slightly lopier idle and the street manners are very close to the old 224 cam. Plus, look how flat the HP peak is.
It's making 430 rwhp from like 6000 up to 6900, and I didn't lose hardly any low end either. Simply amazing! Can't wait to get to the track now!
BTW, thanks to Candy and Allan at FMS for your help. FMS / Cam Motion rocks!

If u picked up 5RW from injectors/3in ORY then the cam was worth 19RW.Thats impressive for sure,add a LSX/90mm TB and it'll go another 15RW.I might try a 232-234 595-598 112+2 in my car this winter over the 224-580 113+2 I have now.
I hope to see these kinds of results.

Be sure to check your P-V clearance with that cam....I had a 232/.595" 111+2 in it and it didn't fit in my case.

When I was running the F13 I had a 112+2 it was VERY close on the intake on the unmilled LS6 styles and 2.05 valves. I ended up having to flycut when I tried a cam that was 232/230 110+4

What is the intake centerline on your cam? Isn't it a 113 lsa / 113 icl? If so, it would fit slightly better than mine even.

....j/kMy cam is on a 114 ICL unfortunately. I had to do this because my motor was making insane amounts of cranking compression with my old 110 ICL cam, so I had to raise the ICL to reduce my dynamic compression and/or "bleed off" more compression.
However my lil FM13/114ICL cam makes just as much TQ at 4000 rpm's as any of these big dogs, with 4 degrees higher ICL to boot in most cases...
FMS rocks...

Nice numbers!!
I thought SVO 30# were causing HP # to drop on most cars. I have a set but I read 4 posts about this problem and was starting to second guess my build plans. If anyone has any input on this please share.
