I was thinking that both of these cams would produce near the same performance, but was wondering does anyone have dyno sheets to show the comparison. I have narrowed my cam choice to these two cams, but was trying to make final decision. Both cams will be on a 112 LSA.

TR224 - Thought about buying from Thunder b/c I like there service and they treat me right, but for 429.99. I would only spend the added investment if there were added benefits to gain with it.

TSP225 - I like the 389.00 price b/c of the savings over the TR224. If it is going to be the same performance as the TR224 I will chose this cam due to the lower price.

Now, my car is a daily driver not racer. I like the smaller cams for the added torque under the curve. I have/will have all bolts on before the cam install EXCEPT that I will keep the heads (casting 853) stock until I upgrade to 5.3L ported and polished heads. My car will be NA it entire life, no nitrous or forced induction. Looking for that near 400HP/TQ numbers with stock heads.

A member here has helped me a great deal and pointed me to either cam, so let's see where this thread goes. Lay it all out on the line fellas and help me make up my mind.

I had the Tr 224 in my car, it is a great cam. I was running 124mph with it.
I put in a TSP 225 cam and it ran 11.1@125mph all day.
I never did dyno it after the swap, both cams are about the same but the 225 has more top end without hurting the low end. This was in my Datsun 240z.

In my LS1RX7 with the TSP225 cam I was running 124mph Dyno 429RWHP 405RWTQ
I now have the TSP 233/239cam Now I run 11.1@127mph with this cam, I have not been back to the dyno yet. The TSP has more low end than the 233/239.

I have the TSP 225 and like it so far. I am still tuning it but it makes good all around power, especially with a good st of heads.

I would think the TSP should make good #'s with stock heads but dought the Tq will be that close to 400. More like 375 to 385 Tq. That is plenty.

My old T1 cam (Lunati 221/221/.559/112) made 380HP 373Tq with stock heads minus
a few bolt ons with my old Z28. Now that is a badass small cam that is easy on the valve train.

Yes, that is the "close" to 400 I was talking about. The 225 is looking good for me.

I have the 225 on a 114 in a 98' M6 WS6 with 4.10's. I put down 383/374 with all the bolt ons, LS6 manifold. The cam has a broad hp/tq curve and pulls hard to 6,500rpm.

My opinion?

If you don't care about squeezing out that extra 5hp or so, then go with the cheaper cam.

If you do care about that, then you should buy NEITHER of those. You should instead get a custom cam that is designed for your setup and application.

*UPDATE

I got the cam in Fri night, broke in the springs by Sat. night with a few heat cycles..

I'd say go with the 225, or get the 226 if you can, which is what I got. It cranked right up and found the idle in less than a minute and I just started it and got out of the car to fill the radiator...no giving it gas to keep it alive. Stock tune and it runs great...died on me twice, once yesterday and once earlier today pulling in my driveway...I need to drill the TB and it shouldnt do that any more. Working on getting a tune by next week...will update again then...

It pulls strong all the way to 6200 where the rev limiter is now, I have talked to a few people and will prob set it at 6700 or so. Im sure it will keep pulling up there, at 620 it feels as though there is more.

Hauls ***, and I can break my 275/40/17 BFG DRs loose in 1st and 2nd again....before I had to really pop the clutch to do that. If I had the stock tires Im sure it would break loose 4th lol.

Also, I just LOVE the way it idles, and has just the right amount of lope. Very driveable, has more power at every rpm, especially up top. A tad bit of cam surge under 1400 rpms with the throttle closed or at like 5-10%, but not always, depends... but I will see if the drilled TB clears that up too...

All around a nice mild cam that I suspect will put out very respectable numbers once I get an LS6 intake and a pulley...

Pulls harder in all gears....even 6th. BTW I have 4.11s so Im sure that helps with the driveability of the cam....
