Well, I will be going a cam swap in the near future and am still undecided on what to get. I was leaning towards the Torquer v2 for a while, but have been reading about the Torquer v3 and it seems to be a really good cam.

My car is a daily driver so i want something streetable.

I would like to reach the 400rwhp mark with my current mods (In SIG) cam only.

What are you views about both cams and why should I go with one over the other!


Thanks

 

Have you read up on DCR, here is a link to the writeup:
https://ls1tech.com/forums/generatio...sier-than.html

You can run those cams on a stock 98 head if you want. To make them perform really well you need more static compression ratio to get the DCR up around 8.5. I put the numbers in the spreadsheet for the torquer V2 (I used 114 lsa and 4 degrees advance as well), 66.6cc chamber and 0.052" gasket thickness and I got a DCR of 7.88.

If you keep the stock heads I would go with a smaller cam if I was you.

 

If you are keeping stock heads I say get a 224/224 or 228/228 @ 112. It just depends on you and how you want your car to ride/idle. You will be at around 400 rwhp give or take with your M6.

 

I have stock heads now, but eventually would like to switch them out.

 

I recommend getting a 228 and switching the cam out to the T3 when you do the heads.

 

youll miss your stocker in traffic with something that aggressive without the compression ratio to match it. My solution would be save the money and do it all at once and do V3
: D. What heads you thinking of getting?

 

well the TV3 should be alot better than the TV2 since they revised it. but my only thing about the TV3 is the huge lift. im not too comfortable with that. i would say just get the TV2 and go with some AFR or trickflow heads.

 

i voted v3. i wanted the v2 also but i wanted something with just a lil more lower rpm range. so ima be going with the v3 some 5.3 heads for higher compression and a .040 head gasket for just a lil more compression. hoping to be 11.1 comp. plus some 4.11 gears will be giving me that quickness to get into the cams rpm range to were it pulls. so all this should make up for that lower rpm lag from a big cam. but a bad to the v3 is the high lift and the ware and tare on the valve springs. from what im told you will need to change them every 10 to 15k miles. but if you dont mind it go for it its all about what your shooting for.

 

im goin with the torquer v3 and here is y:



"The problem with camshafts is that they're completely subjective. What one thinks is perfect another thinks is too big, too small, too much, not enough, etc. Below are the specs on both camshafts:

Torquer v.2: 232/234, .595"/.598", 112 or 113 LSA standard
Torquer v.3: 231/234, .643"/.598", 111 LSA standard

There were a few goals in designing the T3 cam:

1. better low-end and mid-range compared to the T2
2. more aggressive ramp rate on the intake for better power
3. all around great street/strip cam that is very driveable with a good tune

As you can see, the T3 does have one less degree of duration @ .050" on the intake. It's a more aggressive lobe that ramps up faster vs. the lobe on the T2. It provides greater net lift and allows for quicker opening and closing of the intake valve. Again, whether or not a cam works great in the mid-range is dependent on what you're comparing it to. A smaller cam like our 224R or 228R will provide you with a little more low-end power, but it won't make as much peak power. The T2 camshaft was designed to give customers the ability to make some great power without going too big on cam and without feeling like they didn't go big enough. The T3 was just a revision of the T2. With all other variables of a camshaft held constant, a tighter (i.e. lower numerically) LSA with added advance will help low-end and mid-range power. You can change just these two aspects and completely change the characteristics of how well a camshaft works. The goal is to find the happy medium where the cam works well and makes great power without falling off too quick up top or completely lacking any oomph down low. Some of these issues cannot be 100% solved with adjusting LSA and ICL. A lot of duration relative to the size of the engine is still going to have certain characteristics that go along with it, no matter the LSA or ICL.

The net result is that the T2 and T3 will make comparable power. The T3 is going to provide you with a little more low-end and mid-range power vs. the T2, and it also gives you the capability to use a little more of the flow potential of a good set of ported heads.

Thanks for the input.

I think I will be going with the v3.

As of heads i was thinking either some PRC stg 2.5 5.3l heads or some ported 243's

 

G5X1...just personal opinion though.
I liked the torquer v2 a lot until i found the G5X1

 

I have a cam like a TQv2 and my car makes great low end power, 385ft-lbs in the 3k rpm area with a peak TQ of 415ft-lbs. Of course the car has small chamber heads and tight quench though. The car is good on the street too.

Either cam is a good cam and I doubt the power difference between the 2 are barely noticable more than likely..

post number 9 on here is some very good info...

 

go with the prc 2.5 5.3l heads. but if you want to mill them you will have ptv clearance issues unless you buy the heads and cam kit from texas speed since they take care of all the issues before they send them to you.

 

I never like the huge lift on the intake of the V3...

a say go custom...no reason to settle for off the shelf...talk to pred or patrick...I know i was happy i did with my custom cam

 

If I were you and you have a stock ls1 short block I would use the thicker mls gaskets because with the tv3 and 5,3 heads you piston to valve clearance will already be really close. It should be in the .070-.080 range with unmilled 5.3 heads unless you get the 5.3s with the ressesd valves.

 

I voted neither because I would go with a custom grind cam. My last combo was with a tv3 and stage 2 heads and I loved it but now I went with a custom speced cam. If it were between the v3 and v2 definetly go with the v3 though. I was really close to using the v3 again though if that helps. Pretty much any cam you go with you will need to check you valve spring every 15k miles.

 

The tv3 is to hard on the valvetrain with its .649 lift. For a daily driver you will be replacing springs more than you want to.It dosent make much more power than the tv2 5-10 hp max.

 

Not really related to the OP, but I've been looking at h/c packages. I'm in a completely stock 98 TA right now ('bout to get the Rumbler in a couple weeks) and money is kinda tight right now so I can't afford both the heads and the cam. Should I hold off and wait til I can afford both, or do you guys think I'd be fine dropping the cam in and running it til I can afford the heads?
