FMS 226 or TSP 231/237?
Will run either cam on STOCK heads through a SS4000 with a moser 9" with 3.70 or 3.90 gears(still up in the air about that one) Now on to the cams...either the FMS 226/226 .575 114 lsa or the TSP 231/237 .598/.595 112lsa. Mike H. has the 226 and has posted up some great times in his "cam only" set up. However he is running a bigger stall (pt4400) and 4.10's
Dont know many people running the 231/237 in an A4 so i dont have much of a comparison there. Also, many of the dyno numbers between the two are pretty similar, but most of the numbers and powerband ive seen for the TSP cam have been through an M6 or ported heads or both.
So, I need your opinion on the "better" of the two for my application.
Thanks for your input.
should have it installed by some time next monthTrending Topics
Yes, the TSP cam is a bigger cam, that is a given. This cam would be pushing the envelope as far as cam size for what im looking for in my application. But with all of the feedback on this cam, I believe it would work well in a daily driver with the previous parameters given in the set up I would like to run it in. I also believe this to be true for the FMS 226 as well.
So, maybe the question I should be asking is if the added duration and lift as well as the tighter LSA of the TSP cam worth enough extra power over the FMS 226 to justify the shorter valve spring life and a possible drivability factor (as compared to the 226)? Also, being that I have no times for a "cam only" TSP 231/237 in a similar set up to Mike H.'s, then would the bigger TSP be worth a shot so that i would have to find out on my own? If that were the case then maybe I would go with a custom grind since I would be throwing a few variables in the air anyway?
Any thoughts?

I would replace springs just as often w/either one IMO.
Why not call & talk to Allan & get his thoughts?
If this is a daily driver A-4 is the 231/237 what you want?
It's a great cam, but your gonna have to sacrifice one way or the other.
MY opinion would favor the FMS cam. This is likely due to the fact I have seen FMS cams in action over and over again. They perform. I only have one experience locally with the TSP 231/237 and I didnt like the power under the curve. WIth this guy having an auto, that may not play an important role, depending on his stall.
Given the 2 cams, I would also put drivability and tuning in favor of the FMS cam for an auto. I know lotsa guys have the TSP in their A4, but drivability is also a matter of personal preference....
BTW, second hand info on girls is about as accurate as most of the info you get off the internet.... Guys will rip on a girl just because they got rejected...
Ask Bad Andy about that one
To contribute to the info, here's a link to my dynograph with the TSP231/237 with my old exhaust setup. The peak numbers read too high, as the output is more like 400rwhp even, but the curves are informative.

One can order the TSP231/237 on a 114, but the TSP guys put the 112 in A4's all the time with proper stall.
Personal preference is two words. I had to type a damn paragraph to get my point across thanx to you.... 

Oh yeah, I picked my girlfriend out about 15 years ago. She was a keeper.
I asked candy about how long 918's should last with the FMS 226 cam, she said 1 1/2-2 years, though one of their friends has been daily driving his for 40k miles and has no problems so far.
