TSP 233/239 .595/.603 113 vs. Futral F13 230/232 .595/.585 114
Did anyone compare the performance between these two cams?
I'm looking for a cam that's more suitable for road racing - not drag racing.
Maintaining low end torque while providing great power under the curve is more important to me than peak hp/tq numbers between 6800 to 7400 RPMs.
If you're running one of these cams - please post your dyno graph. I need to compare the performance of these cams across the entire powerband.
This cam is going in an LS6-based 383 stroker. This is my dyno graph with the F13 (114 LSA with a +1 Advance) - would I achieve better results with the TSP 233/239 cam?:
Thanks!

Phil (Phil99vette on this forum) ran the 233-239 on his drag car. I think it was a 111 LSA. You may want to contact Phil and se what he thinks.

Both cams are kinda peaky, id say for power under the curve your gonna want a slightly smaller cam, say a 228/228. Both cams you mentioned are great but more for drag racing IMO.

Why do you want to spin it so high for peak power???

Please re-read my post. I'm not looking for a cam that has to spin high RPMs to achieve power - just the opposite for road racing.

AH... I would recommend the F13 on a 112lsa and 108 ICL. I had this cam and it was a TQ machine....
I made 350rwtq (SAE) at 2400rpm... and I think peak HP was at 6100rpm.

Whoops didnt see it was going into a 383 stroker....yea anything around a 23X/23X should still be good for a lot of low end/mid level torque/hp in that motor. Also just out of curisoity is it the lower the lsa the lower the powerband, or is it the ICL? I believe its the LSA but not positive as ive heard quite a few people mention that?

I have a 383 LS6 motor with this cam FM1-RJ-111 FMS Custom Grind Camshaft - 236"/239" .600"/.611" 111LSA. I dynoed it w/o a good tune and it made 460rwhp and 454rwtq. Car pulls VERY hard above 3100rpm and will rip the rubber off your tires. Not peaky at all. I believe its making around 475rwhp/465rwtq now...guessing via HP Tuners injector usage. Sorry but i dont have a scanned dyno graph.

Jimmyz - thanks for the info. You're pulling down 20 more torque but less than 10 hp at the rear wheels than the F13. However, the RJ cam begins to pull at 3500 rpm. The F13 begins to pull at 2500 rpm. Texas Speed advertises their TSP 233/239 cam as beginning to pull at 1900 rpm, which is perfect for road racing. I'm hoping someone can chime in that's using that cam to confirm and see their dyno results to see where it begins to drop off.

That TSP cam is almost identical to the Comp Cam I'm putting in this weekend. I will have it back to the dyno the following weekend assuming nothing goes wrong. The comp cam XE-R I'm putting in is 232/239 .595/.605 on a 114LSA. So its very close to the TSP and if I'm not mistaken the TSP cam uses XE-R grind lobes. So maybe I'll be able to tell you something next weekend.

Great - your cam specs are very close to the TSP cam which is based on the Comp Cam XE-R series cams. I'm looking forward to hearing about your results and checking out the dyno sheet.

I have the TSP233/239, Have only run one 15 minute road race last year due to oil pump problems, but I can tell you that cam works great in my 346 C5 with CNC heads. Great power, peaks at about 6000 on my G-Tech. I shift at 6500. Good pull from 3000 in 2nd gear to 6000 in 5th. Very strong at redline. It's great. I will post some chassis dyno numbers in a few weeks.
