ms3 / torquer v.2 / 233/239

ls1kbush · 11-02-2009, 12:57 PM

Im stuck between these 3 cams. They all seem to offer about the same lift as well as duration but which one would perform best with Hooker LT, slp catback, ported 80 mm tb, m6, 4.10 gears, and ive got a wieand intake that came with the car when I got it and ive herd I should sell it and get a ls6 intake but im going to port match the wieand and clean it up inside and use it since I already have it. Ive also thought about the polluter cam but it seems to have alot more duration. Any of you using any of these cams please let me know your thoughts. Thanks

all are really similar. should be minimal difference in power.

off the top of my head i would say that Tv2 would have slightly better street manners and possibly a small amount more torque down low. not sure it would ever be felt though.

if you plan to do heads down the road...might be worth considering that into the equation. the cams with really high lift/duration will affect how much you can mill a head or run bigger valves.

something to consider.

None of the above, I would go with a fairly decent size cam though if you plan on sticking with those 4.10's.

ls1kbush · 11-02-2009, 01:51 PM

I dont plan on doing any work to the motor or the heads other than valvesprings. I might put some 243 heads on later but dont plan on doing much to them other than a little porting. Not trying to build a race car just something I can drive most of the time with reliability and be able to take to the track and run decent times.

4.10's dont seem like much of a gear when I can go down the highway at 70 mph at 2k rpm's. Maybe with 4.56's I would recommend a big cam but I think these cars should have came with 4.10's

4:10 is a big gear and the MS3 is big too by the way.. They go very well together along with 233/239 and polluter. With the TV2, you could step down the gear without prob but the other cam might result with beeing a dog down low.

You said youre driving most of the time; I would go with TV2 or even lower for DD like the 228R cam.

And if you dont have rod bolts upgrade, you better be safe and not the spin the engine higher than 6500-6600..which will be the case with MS3 and 233/239.

I've checked some dyno results with the polluter and it seems that it doesnt peak that high(around 6500) so it might be an option.

4:10 will help street manners of the big cams, but you will still need to rev high..

Finally, bigger cams like better heads and intake setup, so you might better off with something like TV2.

I bought a TV3 that I may put in next year. You should check this cam this latest version of the torquer.

Obviously with the MS3, you would need dual springs, but do you need the duals for the TV2? Since it's .595/.598, could you go with .600 single springs? Or would you need more since that's so close to .600?

It wouldnt make sense to me to run a spring that will be maxed out all the time rather than spend a few more bucks to get .650 springs that would also last longer.

Johnnystock · 11-02-2009, 03:05 PM

You dont need the double on the TV2, the new version of the singles are rated to 615-620 lift max. Doubles with TV2 is a bit overkill and I would check what TSP has to say about the MS3 for springs.

Aggie_Ls1 · 11-02-2009, 03:09 PM

Have you ever thought about a custom grind? You can get a cam made specifically to meet your needs without costing much more at all.

True if you buy a brand new cam, but you can get nice deal outta like new off the shelf cam..

I was thinking more along the lines of if you went with the duals, which are rated high (~.650) you're going to be adding some good friction, taking away some hp. I just didn't know if the singles would be enough for the T2, but I also didnt realize they made singles that are rated 615-620. That would be the best bet obviously.

teke184 · 11-02-2009, 03:42 PM

for a reference....my TSP torquer V1 peaks at 6300rpm...even with the big FAST on it.

nice useable pwer and not reving to the moon!!!

my vote of those is def the Torquer.

I would most likely not have a custom ground cam for the reason of these other cams have proven hp gains. That to me is worth purchasing a cam that I have an idea of what its worth.

I couldnt believe that there would be more friction because even with the .700 lift springs they are rated at 460 # open pressure but did you ever think that the pressure at .600 lift is much less and with a roller cam with such radical lobe design you need as much pressure as you can get so the lifter will follow the cam and not cause valve float. Also if using a .700 lift spring is going to rob you of power with friction then how does a .700 lift cam make any power?

it is so hard to deside, i have the ms3 and still have to put it in, the one good point made is if you plan on getting a big came that makes power to 7k, you will have to do rod bolts, from what i have read it sounds like the rod bolts dont hold up if you spin them over 6400-6500 rpms. Just something to think about choosing a cam cuz it adds alot more work to change out the rod bolts

ls1kbush · 11-02-2009, 09:12 PM

I understand the rod bolt problem and to me thats not any concern at this point because I can do that sooner or later its just a matter of not spinning it that high till i change them.

jcobra99 · 11-02-2009, 09:19 PM

Go with the Torquer V.2. I have a torquer v2 on a 112 and it sounds mean. It pulls like a demon above 3400rpms. It also is VERY streetable with a good tune. YES, get DOUBLE VALVE springs. I would never trust this cam on some singe 918's espicially since it has xer lobes. Better to be safe than sorry when it comes to broken valve springs.

I plan on running the PRC .660 springs no matter what cam I go with but if I can get a deal on the .675 I would go with those.

DarkJuggalo · 11-03-2009, 01:53 AM

i voted polluter, the deluxe kit is a great deal and the cam has proven itself very well. this is the cam im hoping to do soon
