Well I just switched over to a new cam. Trak from thunder racing. Specs are 231/234 .644/.598 112 LSA on a 110 ICL. I previous had a 231/237 .598/.595 112LSA on a 110ICL, and a 224/224 .565/.565 110LSA on a 106ICL.

Comparison's:

TSP 231/237:
This cam loped pretty hard and had a decent power band, it idled well and I enjoyed it. It didn't make crazy power, especially for how big it was, but it's a decent cam especially for when it was designed (fairly old, one of the first large cam's) Power from 2800-6300

Comp XE 224/224:
Bought this cam to get a lower power band. It did the trick. Car power went down to about 2300-6000. It felt a lot stronger than the 231/237 around 2500rpms. Car made about the same rwhp and 15rwtq more than the 231/237 but at about 500rpms lower. Had a nice idle and drove similary to the tsp cam.

Trak cam 231/234:
This cam is big. It idles similar to the tsp cam but a little louder, and better sounding. The car sounds cleaner and a little louder. The power isn't there at 2500rpms like before. In fact it's probably less than the 231/237 cam. It's gotten better with driving so it may just be in the tune. It definatly needs it as I can smell the fuel big time. This cam pulls much harder than either of the previous cams. I'm extremely happy/impressed with this cam. I'd recomend it to anyone. Power band 3000-6xxx(I haven't gotten past 6000, but it was still pulling hard)

Nice reviews, even makes my decision harder now.

Also if I were to go with the 224 cam again I would get it on xe-r lobes probably so you have got a little more under the curve power. I just had stock lifters and wanted to be safe. I ended up replacing those anyhow so, you live ya learn.

I'm interested in this cam too. Post up more info as you get it sorted out. Thanks for the post!

Do you know if this cam will fit under unmilled 243 casting with a 62cc chamber and stock sized valves? also are you planing on putting it on the dyno soon? I would really like to see some numbers? What does the TQ feel like in low and mid RPM's and the street manners?

Thanks, Matt

yes its a great cam i recomend it too i ran this cam for two month and i shift
it at 6700 rpm i havent dyno it but its 400rwhp + with bolt ons for sure.
and with a set of afr 205 it will be great

I don't have a problem down low with the cam. I am making around 320 rwtq at 2500 rpms. The cam pulls very strong up top. I run mine to 6800, and it really feels like a damn rocket. The highest dynoed numbers were me changing to a FAST 90/90, March Pulley, and a cutout. My old exhaust was extremely restrictive. The lower numbers were from and LS6 intake, unported tb, and **** *** exhaust.

I'm not sure. I'm not planing on dyno'ing it yet, because I'm undecided on whether or not I am getting heads. I was going to, but now I might have to spend the money elsewhere, so we will see. Right now there isn't a whole heck of a lot down low, but it definatly isn't bad. Street manners are fine, and I'm still on my old tune. I can smell a lot of fuel so I know I need a tune.

its kind of hard to judge a cam if your car is tuned for a different one...your power down low may not be that bad once it is tuned

iTrader: (21)

I'm sure it won't. That's what I was saying. It's going to be a beast when I get it tuned since I know it needs it by the smell of the fuel.

Very informative post. I am in the process of installing my TRak cam with STG 1 PRC's. Looking forward to getting it finished. Do you happen to have any sound clips? Thanks!

turbo I am looking into a similar setup, have you checked piston to valve clearance? What size pushrods are you using?

Glad you got the cam in Kevin. Keep us posted how it runs with the tune. You should be able to run it up to 7000rpm, no problem.

LS1impulse, TSP told me they use the MS4 with the PRC LS6 heads without any p2v problems. The TRak cam is smaller so it should fit with no problems. I'm using stock H/G's, no milling and the stock size valves. I'm still gonna check it. Oh, 7.40" hardened pushrod.

Patrick G, can you shed some light? It shouldn't be a problem, right?
Also, how was the drivability with the TRak cam? Wanna take a stab at how much HP it makes? BTW, Geoff at Thunder is gonna tune it.

Patrick G

iTrader: (14)

TRak cam will easily fit a stock motor, even if it has thinner head gaskets. Geoff is the master at tuning this cam. He's dialed in dozens of them to perfection.

The car is becoming more and more undrivable as I put on the miles. I need a tune.

how low in the RPM's can you go with this cam?

777

iTrader: (21)

I'd say you would start to run out of steam near the 7000+rpm range. I'd say peak power is around 6300 so it would carry for a little while after that. Patrick would know a little better though.

Im prety decided on this cam as long as i can find some assurance that the patriot 243 castings (either stock or aftermarket valves, unmilled) will fit with no p2v clearnce issues.

And any ideas on the power this setup will make with all the supporting mods?
