TSP 231/237 or TSP 233/239
TSP 231/237 or TSP 233/239 OK guy's and gal's I am currently looking to go a little bigger on my cam in my 02 WS6. I currently have a TR224 that made 393RWHP on my stock tune. I am looking to go well over 400 with a tune on a new cam and I am pretty sure I would be easily over 400 with a tune on the TR224 but I am getting the itch to go bigger. I am stuck between the TSP 231/237 or the TSP 233/239. I am going to keep the comp 918's and TR pushrod's so I am not sure if those Spring's will handle the 233/239. I also spray a 150 Shot of nitrous too my car too. So help me pick the one that is going to be fairly streetable and make 400-425 off the bottle and 550-575 on the bottle. Thanks
actually the ramp rates on the 231/237 will be a little easier on the 918's than the 233/239 will. My understanding is that while the duration isn't all that different, TSP used a much more aggressive lobe design on the new 233/239 design. So, if you're intending to reuse your 918's, then i think the 231/237 would suit you nicely. Also, the split on that cam is well-suited for your nitrous.
TSP used a even more agressive ramp rate on the second version which is the 233/239R2. TSP recomends that cam over the 231/237.

I had the TR 224/224 114 in my car with the 918's. Good cam but, as with all of us...I wanted to try out something bigger.
Called TSP & talked to Jason and got the 233/239 and I'm using the 918's still. This cam works excellent, pulls like a mule around 3K, and sounds kick ***.
Just my .02

Thanks for the reply's. I am leaning toward's the 233/239 right now but I think I will call TSP today and run it by them and tell them what I have and what I want out of the car and let them pick the cam for me.
As far as keeping the TR224 (5POINT7) I have thought about that but now I am curious to know what I can make with a bigger cam. Like I said I want 400-425 on motor and I think if my car like's a bigger cam with a tune I can get there. Thanks again for all the info.

Hey Cal, how do you like the 235/240 cam? Im thinking about going with that cam to use with the PRC heads (if TSP determines they will fit) instead of the 233/239 cam.
2002BLKTA, If you decide on the 233/239 cam I may sell mine. Its never been installed, in fact I haven't opened the tube to see it. You can PM me if you want it.
Well I called and ordered the 233/239 today. Should be here by tue's or wed's. I am going to stay with the 918's for now and get some dual spring's later. What do you guy's think am I going to be OK running the 918's for a while?
I still want to know how he put down 393rwhp & 385rwtq w/a TR224 114 lsa on a stock tune!?! Are those 241 heads that much feking better than mine? My car is tuned and only putting down 375, could get more with some timing but I dont think 20hp more. WTF! Swap meet this weekend I'm going looking for the 241's!

If the 233/239 V2 has a better low end tq (as it should) than the 231/237, go with the 233/239 hands down.
I love my ol' 231/237, but the low end tq was simply not there until my latest round of bolt-ons (QTP HVM LT's and 90/90).

i don't know if i like the 231/237 cam i mean it's a beast for me but this is my first ls1 and it's putting down the numbers in my sig...there's no low-end on the 231/237 id much rather have a futral cam and i almost thought about swapping cams when i was doing the oil pump and timing chain swap...i'll just wait till i can go with a bigger engine and then get futral to custom grind me a BIG cam...course it is really kind of hard to judge this car on street tires cause there is no traction at the top of first, or 3/4 through second...the clutch and tranny have also seen better days so i'm sure i could get some in third as well, but i have to granny shift to not grind

Anyone looking for a 233/239, I have one for sale? PM me bud with your dyno runs!
