Has anyone checked the power diffeerence between this cam, to me it seems like 231/237 is the obvious choice for power but i was wondering what you guys thought...

The power curve of the TR224 may be better for around town bursts, but the 231/237 will ET and Trap better. Conservatively, there's probably about a peak 15rwhp difference between the two.

thankyou much.

Don't forget about the TSP 233/233.

the TR 224 and TSP 231/237 are in two different ballparks....IMO

it depends on where your talking about this power. from idle to about 5500 rpm the tr224 properly tuned will out power the tsp231/237. from 5500 on the tsp231 will pull away and net you a ~20rwhp at peak.

all depends on what your application is and what your willing to trade off.

i was just wondering about how they would compare, i kinda knew the 231/237 would outpower the 224/224 in the 1/4 and the low end but was wondering how much, what do you think about the 233/233 torquer compared to the 231/237? being the torquer's lifts are that much smaller?

you wont get much of a response on that one other than the 231/237 will net 5-8 hp more on the top end than it, but it will make more tourqe in the low and mid range.. the 231 will net slightly better ET's but the tourqer will be a little better around town....those seem to be the only answers iv been given so far about this cam and those came from the guys at TSP and i have heard the same answers here a few times... still havent seen any dyno graphs or heard any track times with the torquer. its the "MYSTERY CAM" but caome sping, i will have all the details on it first hand from the dyno to the track.

Lets also bring up the topic of gearing. The TR224 is on the fine line of being undergeared meaning the stock 3.42s are just doing the job. With the 231/237's lazy lobes it would be awful with anything but 4.10 gearing. Unless your going with 4.10s or lower then the TR224 all the way. I also think the 231/237 is only good for 8-15rwhp max over the TR224.

Agreed... I don't think I'd like my cam's powerband as much as I do if I didn't have at least the 4.10 gears. In fact, I'm contemplating making a switch to 4.30s because I think that ratio would be about optimum for the 231/237.

Ok i sort of understand this concept of undergearing a cam but could someone explain it a little more detailed to me.. like why are 3.42's not optimum for a TR224? THX

Vertigo, I believe what they are saying is the TR224 will be fine with 3.42s because of the increased lower power compared to the 231, where (I believe) it makes less lowerend power, but pulls in the greater rpms. 5k+

well , i think there is something inbetween which is fair in my opinion the MTI G1 228 232 575 588 113 ... great results .. like maxing the Tr224 with TSP`s

Be very carefull with the larger cams, they can slow you down if you are not set up for it. My car went 11.1@124.8mph all motor with a TSP 225/225 589/589 cam. I later put in a MTI X1 cam 230 227 .591 .571 112 and it slowed me down to 11.6 @ 119 mph. I made more power on the dyno with the larger cam but my 1/4 mile times slowed down.

I have also used the TR224/224 cam--it is a very good all around cam.
The TSP 225/225 589/589 gave me 1mph and .1 in the 1/4 over the TR224 cam.
