Hey guys I have a 99 trans am m6 with bolt ons looking for a nice cam for a street driven car. Not a daily but take it out once or twice a week. I came across the btr stage 3 ... 231/242 .617"/.592" 112+2. Just wondering if anyone has run this cam? Looking to see how the drivability is and what sort of number/track times anyone has gotten. I can't seem to find much info on this cam.

Thanks, Chris

 

I tuned one in a friends 6.0 swapped 2nd gen. Never got any numbers but it ran good and is pretty tolerable to drive around town. His was an auto so a manual would probably be even better with it.

Should make around 400rwhp if you have all the proper supporting mods.

 

I've only heard positive things on those BTR cams

 

My T/A has that cam.

It's been in the car since around Thanksgiving. Long story short I had plans of mimicking a buddy's old T/A as the car looked identical. His car had an old LG G5X2 112 (232/240 with similar lift) and a set of kooks 1 7/8 headers that's it nothing more. Nick Williams tuned the car and it made 420 rwhp and 390 rwt on his dyno. No one believed the car made that kind of power cam and headers only.

Another friend of mine has a dynojet so we figured for giggles and bragging rights.... what the heck lets try this thing again on another dynojet. The car made 422rwhp and 387 rwt.

When I bought my car it was purposeful everyday driver. I looked into the LG cam and then it struck me, maybe it's time to look at some similar grinds from other pro's than are on newer lobes. The BTR Stage 3 N/A was right there, so I ordered it, with plans of keeping the 241's just upgrading the valve springs. Quickly after ordering it from BTR, I got to looking around at possibly doing heads and it became apparent to call A/I as they are within 25 miles of me. As I contemplated doing their 241hc, $1200 for a set of stock castings? I think not, ended up buying a set of TFS CNC 205's which was the best of both worlds in my eyes.

My goals were a fun torquey DD that sounded mean and ran well N/A,
58cc chambers for added comp and more valve clearance for the stock pistons. It's about 11.5:1 now so this cam is not what I would call optimal for these heads, however it happened so fast and the cam was already in the motor that I decided to build it on up and start driving it. Called the local tuner ordered a base tune, and setup final dyno tuning for January 25th. Toward the end of next week I will give you some hard data to decipher through if numbers are your goal.

The car is very mild in my opinion now, and drives almost like stock above 1500 rpm (6 SPD). It doesn't like lugging around, but hell who does?

This cam makes power from 3k north and is a bit of dog down low. However playing around with hptuners has proven the base tune at 17 degrees max is holding it back. I added around 8 degrees from 55kpa at 4000 rpm and up, and it turned into an animal unleased. Its a well mannered cam that will be fine for DD and may do even better with a stock set of 241/243 castings. Brian said it was better suited for stock type heads.

 

Sounds like a nice cam ... looking forward to see your results. Hopefully my tax return will be decent this year and I can get everything on order soon ... thanks for the advice guys

 

5hat should be a tuff set up. Do you have stock rear gears?

 

It runs very well, is it optimal? No but it does get the job done while having a very mild mannered around town feel.

3:42 gears are in place now. Month or so back I purchased a QE 9 inch and had an aluminum center chunk laying around with 4:10's. I'm contemplating daily.

Plan was to wait until it was tuned to see how it does then.

 

Have installed the BTR Stage 3 cam in a few different cars and they always had good street manner and made the numbers they should have. I am actually going to be using this cam in my personal C5 Z06 with a set of Trickflow heads.

 

600lbs lighter would certainly make things intresting. My bets are it' will be a blast.

What's the head specifics?

 

I've been thinking of this cam in a 5.3 stroked to a 5.7 with Trick Flow 205 heads running through a 60e tucked into a '67 Chevy II Nova. The intake would be a TBSS with a 92mm tb. I think it would perform for a street cruiser. Tell me if I'm wrong.


What about rear gearing? I was thinking of 3.42 with a stall of 3600-4000. I've never driven an auto with that type of a stall. I'll will be running 18" wheels in front and 20"s in back.

 

It would run very well . So far with the minimum tuning I've done with HPT pro it's very surprising how well it drives around town.

Gobs of torque.

 

I"m looking at possibly putting this cam in my basically stock 6.0 LS swap but I'm fearing it's a little big with no head work or larger stall (Currently have 2800 stall).

 

You would be correct. I would take things down just a bit.

The Cam Motion Titan 3 comes to mind. Maybe the Titan 4 but that's getting to the higher limit.

I'm sure Brian Tooley's lower stages would be similar to those.

They'll still gain a crap ton of power over stock but be more driveable. If you add heads later they will still work well and not need changing.

 

PM sent so I don't hijack the thread.

 

Go for it man, I have the BTR stage III in my 6 speed 01 ws6 with 4.10 gears, stock 10 bolt rear, 1 7/8 headers and tune, and it hauls a$$. No loss of low end torque with 4.10 gears, easily a daily driver if I wanted, street manners are like stock. Running through catless GMMG chambered exhaust, sounds amazing. You'll love it

 

What length of pushrods do you use?

 

What length of pushrods do you use?

 

Any of you guys running this cam have to pass emissions?

It won't pass emissions. Not even close.

And the BTR Stage 3 is going to be a rowdy cam. Not terrible, but definitely not a perfect driver with 12 degrees of overlap. The Stage 2 probably fits that mold as the top of what would be pretty much stock-like streetable. However, the Stage 3 will drive better than the Stage 4 and probably give up very little power to it.

I went from the Stage 4 to a BTR Supercharger cam. The tune didn't change much which surprised me. I lost around 10HP and gained about that much torque. But the Supercharger cam carries further by about 200-300 RPM... It's a 227/244 115+5. And it drives pretty much like stock. Most people wouldn't think to run it as an NA Cam... but with 11:1 compression and high flowing heads, it will make power over a very broad area and carry past 7k. And drive very well.
