Specs.
TR230 – 230/224 .571/.563 111+0
FMS F13 – 230/232 .59x/.58x 112+2

I am currently running a TR224/114 cam, 4000 stall, and the other mods in the sig. Which cam will provide the most power gains above my TR224 and will give the best performance at the drag strip? I shift at 6500.


Thanks

ive never used the FM cam, but the TR230 is pretty useless down low... one of my customers that switched to a G5x3 had it and it sucked below 4000 rpm... just my input though

I guess you and I can agree on something. The TR 230 would act just like the 224 cam you have now untill 5200 rpm's or so. Then it will pull away from it. The FMS cam would make more low-end power and still pull away on the big end. I think the choice will be easy.

Thanks for the quick feedback.

My heads are milled .015 with 2.02 intake and stock exhaust valves.
Will there be any P to V problems?
Will the Comp 987 springs that I am running be sufficient with these cams?

Thank

It all depends on how you get the cam set-up as to whther or not there will be clearence issues. You can have it cut on 112 or 114 with up to 4 degrees advance if you like. 112 +4 will be most likley to cause P/V contact and 114 +0 will be the least likley to hit. I'm pretty sure you would be able to get away with the 112 +4, but Futral would know better than I would. The 987's you have will be fine.

I have the stock rear.
My 4000rpm stall converter keeps my engine RPM at or above 5000 throughout the 1/4 mile.
In a ¼ run my RPM is between 5000 and 6500 the entire time. I want to increase the HP in that range.
I already have the TR230 cam (Not installed yet. Still running the TR224.) but if the FMS F13 will make more HP in the above range than the TR230 then that is the way I will go.

Thanks

it would increase it, but not worth a cam swap IMO.

fwiw i am running the Tr230 and i am peaking past 6500

oh sorry thought you still had the 224

With both cams having the same intake duration, I don't think the big end numbers would be worth a cam swap. For a 5000+ rpm plus gain, you might want to look at a G5X-3.

Sorry for the confusion.

I do still have the TR224 installed but I also have a TR230 waiting to go in. If the FMS F13 will make more from 5000+ RPM then I will sell the TR230 and buy the F13.

My TR224 has been very good to me. My best run with it was 11.18 @ 120.24 in the 1/4 and 7.10 @ 96.08 in the 1/8. My goal is to get into the 10s but I do not think the TR224 will get me there which is why I need a bigger cam.

I agree but I feel sure that there will be P to V problems with my heads being milled .015. I am looking to put in a cam that will get me the most HP gains from 5000 - 6500 RPM without having to fly cut the pistons.

Thanks

I gotcha. If you are fixing to swap the cams, then I would go with the FMS. Why sacrifice low-end power if you don't have to? You won't be at the track everyday, so the added low-end grunt might put a smile on your face on a sunday afternoon ride.
