i know this subject has been beat to death iv'e read about 50 posts about these cams. but i am going to buy one of these three. fm11 fm13 or tsp231/237
originally i was going to go with the 231/237 but iv seen mixed dyno numbers between 360-405 hp but it seems the fm cams are more consistent with 385-400hp so question is which one would you go with and why? thanks ahead of time for your suggestions! by the way this will be cam only with jet hot lts
heads will come in the winter probley stage 2 5.3s

 

I would go with the FM 11... because that is what I am going with

 

i have the F13 and just love it. great everyday drivability, even on a 112 lsa in an automatic. plus, it pulls like a mother from any rpm. sounds nice too

 

well im installing a f11 with 114 for rollinsscamaro sometime in the next couple of weeks so i guess ill see how it drives and decide if i want the f11 or the f13
also does anyone know what the main diffrence is in the 112 or the 114 does one have better torque at lower rpm?

 

i was wonderin if you have any track times with your set up and did u put the ls6 intake on yet? also dyno #s tuning?

 

Well I just bought the fm10 but If I were to get a stage 2 heads I would go with the fm13

 

sorry bud, i aint got nothin yet. i plan to be at the track next friday, if the weather stays good. no ls6 either. and i think ls6 heads work better with this cam than the 5.3's but i could be wrong. they are what gomer and damian used on theirs to get in the 470's. and i had my car tuned by tsp by me sending in my pcm. not too many good shops here in NM for ls1 performance. so no, no dyno numbers. i bought the cam used though and the previous owner put 400 to the wheels in an 02 m6 w/ an asp pulley, hooker lt's, and ported tb, so it is definitely a strong runnin cam. i personally would call up alan if i were you and ask him what he suggests. distortion69 got a custom cam in his putting 419 to the wheels, cam only. maybe alan can get you something to work better with that bit of juice. call him and see what he has to say, even though between those 3 i still vote for the F13

 

ya i think i should beable to put down 385hp with my a4
which would make me happy for now.but ill need some heads by next summer i think ill just get stage 2 ls1 heads since i use the juice once in a while!

 

does anyone have a sound clip of the fm13 or fm11

 

www.ls1sounds.com i would send you one of mine, but i dont know how to get a video from the camera to the computer. i know for sure there is an F11 in the hooker catback section.

 

awsume sight thanks makes it easier to decide which exhaust to go with

 

good luck in whatever you decide

 

ttttttt

 

what are the specs on the FM cams? Maybe you should step it up to a TSP Magic Stick v3

 

F13 is a 230/232 .595/.585
make some calls. tsp is a great place with GREAT customer service and im sure they would be very helpful, as would futral.

 

i'm goin with the 231/237 .595/.598 112LSA. i have the followin parts waitin to be installed along with it: YT 1.7 R/R's, ls6 ported oil pump, rollermaster double adj timing chain, and am going to pick up an asp pulley tomorrow...need to buy springs this month....and then waitin til next month for kooks headers....then its all gettin installed by me....

that'll be on stock heads, with a fipk, ported tb, and soon to have sweet chambered TD's, i'm hopin to put down somewhere around the neighborhood of 400 to the rear wheels once i get her tuned in(thats the catch....once i get her tuned in). she's an m6 btw. i'm also gonna put her on a diet.... anyhow, i've spoken to the peeps @ tsp quite a bit over the months and am quite confident with this setup. should be pretty fun
