Torn again between 2 cams: The new CheaTR V.3 or TSP Torquer V.2 I obviously know the differences between these 2 cams but I just can't make up my mind. Of course I want the best of both worlds in performance and fuel economy.
OK so I know the CheaTR V.3 cam has a tad more lift than the Torquer V.2 but has a wider LSA and won't need to idle over 600 rpms like hotter cams. Looks like it has a powerband from off-idle to an LS7-like 6800 rpms. Nice flat wide powerband if you ask me. I also heard that it can lope nicely if idled under 700 rpms. Yet, all the boards tell me that a cam with a wide split duration and wide LSA will feel super lazy off a dig. Tell me they are wrong because these are 2 conflicting points of view. The cam manufacturer vs. the peoples' common knowledge.
On the other hand, the Torquer V.2 cam will lope at idle, will have bad cam surge below 2500 rpms, will need a steady 850 rpms to idle and will need much more tuning. People over at the GTO boards has also claimed that they could get stock-like fuel economy if they aren't ******* the car around all the time. The power band also seems more narrow: operating range 1500-6400 rpms.
People also say that tuning is EVERYTHING when it comes to a cam selection.
I am planning on a set of TSP 5.3L stage 2.5 heads.
Does anyone have a dyno comparison of these 2 cams side by side? Any timeslips from both cams? Thanks.

I run the V2 in a C5 with the TSP 5.3 heads. The car runs great, it has a big converter in it so it just blows the tires off. It put down 396/354 through an unlocked converter.It hits hard through some good flowing exhaust. With a good tune it drives good on the street. The cam makes good power throughout the powerband. Pulls hard from down low all the way up to 6300 rpm.

You sound like me and that's why I went with my custom grind (218/230 .605/.604 116+2) before the v.3 came out, but just so happens to be very simliar...I run the same heads and made more power with this cam than with the previous stealthII I had...fwiw I ran another frc with afr/torquerII cam tuned by same guy and continued to pull him thru 3 gears...my car idles at 725 with only the slightest hint of something going on under the hood, leaving everyone looking for the bottle lol...it has been 7.0@100 and puts down only 425/385, but it's nice and flat...avg power is what wins races, the wider lsa does move icl later relatively speaking, but it's not coupled with a big intake lobe, so it still has plenty of mid range punch and doesn't fall off on the topend because of it's efficiency

So what's a nice low idle rpm for a Torquer V.2 cam? 700-800 rpms? If I get this cam, I want it to sound badass with a lower idle as long as there isn't too many problems with doing that.

Also, that cam still has -9.5 degrees overlap at .050 lift. It will probably not sound "badass" at idle...
Idle-6800 RPM Power Band. Broad power range. Works well with stock exhaust manifolds and catalytic converters. Stock like idle in 5.7L or Larger.

I just got my 01 SS tuned yesterday with my Torquer 2 with a 112 LSA and we set the idle up to 875 RPMs and the car still lobes good at idle and sounds mean, I'm very happy with the Torquer 2 cam so far, haven't dyno'd it quite yet as we only did a street tune yesterday, I'll be posting numbers of my setup up once I get to the dyno in the next few weeks

Honestly you don't tune a cam for lope or low idle. You tune it to run properly and idle at what rpm works best. If you wanted you could tune the stock cam to lope, but that doesn't mean its right. My cam has over 10 degrees of overlap which is about what a torquer v2 would have on a 111 LSA. It's all in the tune, I can tune it to get 28 mpg on the highway and 20 mpg in town. If I want it to not buck and surge the mileage will get worse as you have to add a little fuel down low. I've tuned a heavy GTO with a Trex cam that was getting 11 mpg in town. After I was done with it she was seeing 17-18 mpg in town.

Get a Torquer V2, you won't be disappointed:

Dude that TA sounds bad ***. I had previously been set on the TSP 228R because it seemed to be a great daily driver cam that makes good power, but I was afraid that I would want to go bigger after I got it. After reading a lot of peoples opinions I decided on the Torquer V2 because it makes great power, the lift isn't too high, has a great sounding lope at idle, and many people have said that with a good tune the driveability is great for a daily driver.

Where did you pickup the idea that a TV2 will have a bad cam surge below 2500rpm? Thats totally bogus. Somebody needs to find a better tuner! If you pick the TV2 make sure you get your convertor restalled to the mid 34-3600 rpm range. The TV2 does have a nice chop to it and should put you in the mid 12s in the 1/4 mile.
