Kalijah98z,
What is the LSA of the FM13 cam that you are running? Great numbers by the way.

Damian, thanks for the feedback, but how in the world can you have a STOCK idle, when even Futral themselves advertises the cam as having a "rough" idle??

Great numbers for cam only, threads like this is definitely putting Futral to the top of the list for who I will get my cam from.

I think you can get this cam on a 112 or a 114 lsa

Also I don't think there is any way that the car would have stock idle

The motor is definitely a '02 LS1 w/ LS1 "241" castings. These are proven to make a few more hp than the older "853" LS1 castings (~5hp). This, along with the stock rear/3.42s, and a fresh motor, the #s are definitely believable.

I ran the F13 for a while and it is a damn nice cam. I was really impressed with the power I made with it. I did 474/422 thru a 10 bolt and drove the car every day with that cam. I'm running the F15 (ron jeremy) cam right now and I'm REALLY impressed with how good it drives. I found a few problems with the car today, so expect some pretty good numbers from it later this week when I redyno

Congrats Elijah !

I know you are real happy with the results,and you only wanted 400

The first few pulls were rich,dipped off the graph. During some 41x pulls,the A\F was about 11.8- 12.0,the 430 pull ended up at 13.0-13.2 A\F. Final timing was 28 deg.

I was shocked also and had to make sure it had 241 heads.

Guess he just got a good non-rung out Wednesday motor Also everybodys interpatation of idle is different,we list fair or rough to give customers an idea of idle. This cam does idle good with proper tuning,but not silky smooth like stock.

Would that F13 be a good step up from my F11 Allan, while still playing well with 50-75hp wet juice?

What's the lsa and icl of this camshaft?

Thanks.

Alan is an ULTRA conservative puss ( ) when it comes to describing idle, so let me clarify it a little better for you

The FM13 won't idle "IDENTICAL" to stock, what I mean by "stock" is......It does not die, does not surge, does not hot start, etc....I ran the Fm13 for almost 12 months, and everytime I turned the key the car would fire right up and catch idle immediately, with ZERO driveability tuning need.

I've had several newbies hear my car w/ the FM13 and had no clue. Unless someone knows LS1's, they probably wouldn't be able to tell....

Thanks for the clarification Damian, now lets talk about how hard this cam is on the valvetrain compared to a TR224. Can you offer some insight to this? With the PRC spring kit, how long would you say the valvetrain would be good for before need atleast a spring change?
Thanks,
kevin

Ryan,the F13 will be good step up over the F11,but only worth about 6-8 HP. It will make more power with the nitrous.

Didn't know you had Speed Inc doing you a turbo setup,how is coming along?

Futral

iTrader: (1)

112 LSA,and Jason should have put it at 108 ICL.

Damian

Alan would be the better man to ask about this. I dont have much experience with different valvetrains and the FM13. I ran Comp 987's with this cam and had no problems. I "think" FMS recommends the new Crane 832's.

Also, FWIW my FM13 was on a 114 LSA. The 112 will idle a little rougher.

Futral

iTrader: (1)

We use the Manley #221426, PRC springs or Crane 832's. The Crane's take more shims to get the pressure right,while the Manley's only take one .030" shim and so far the PRC do not require a shim. We don't have much run time with PRC's so I can't give you a good take on life span. The Manley's have been to 20K miles so far w\o any issues.

The F13 is no harder on the valvetrain then the TR224.

Yeah, ive been dealin with them for bout 2 years now with my SS. They just picked up the car Thursday night( since i cant bring it to them) so i guess they'll begin workin on it soon. Will the F13 still act well w/ my vig3200 or should i re-stall? Im tempted to see about getting my TA shipped to you some how if im not healed by late december. More than likely im just gonna get an all new cam kit from you instead of pulling the older stuff out. I should know by mid next week whether ill be adding that nx kit as well. Cant wait!!

KB99WS6

Wow, thats a bold statement. I am not saying you are wrong or anything. Its just a pretty exciting thing if you can make a cam that produces 15-20rwhp more than the infamous TR224 w/no penalty driveability wise or reliability wise....thats pretty amazing if true!

PS-I still can't figure out how a .59X lift is no harder on the valvetrain that a .56x lift cam is....

Can anyone enlighten me????

Futral

iTrader: (1)

Total lift is not the spring killer,unless you get real close to coil bind. Heat,ramp speeds(open\closing) and total valve weight for the given spring is the killer.

I feel that the biggest gain from no loss of drivabilty is just good tuning. The cam design just helps make more power.

Futral

iTrader: (1)

Cool deal,should be killer. The Vig 3200 will be ok with the F13 since it acts like a 3600. Just let us know when you are ready to ship her.

KB99WS6

Allan,

So you are saying that Heat,ramp speeds(open\closing) and total valve weight is no more with this FM13 cam than it is for the TR224 cam??

And would you say an FM13 cam + PRC kit should be good for at least 20k miles before a spring change?? If not the PRC kit than what kit would you recommend for 20k+ trouble free miles....

Damn, every FMS cam dyno I see is pretty impressive...

Do you guys have a setup that is basically maintenance-free for a daily driver and road course car? Looking for power from 3500 to 6400.

Are your lobes more or less aggressive than comp XEs?

Thanks,
Grant
