I was interested in a stealthier cam or a sleeper cam that will produce good numbers? anyone have a clips of any of these cams?

MTI has a clip of their stealth cam on their site. -->

Anybody with a soundclip of an LS6 cam with headers and open exhaust?

Anybody with the TR220? I have been told its docile as well.

I am going the sleeper route

If its stealth, you shouldn't need a sound clip

If your current cam is stock, just start your engine and listen carefully. That's what the Stealth cam sounds like.

Colonel, which cam is that? MTI's or Lingenfilters? what lsa do they have?

Colonel

My cam is the MTI Stealth II cam. 224/220 .581/.581 116 LSA

There is also the Stealth I cam 220/220 .581/.581 115 LSA

The Stealth II works best with a really free flowing exhaust. It really pulls great at high RPMs and should be the faster of the two cams in a free flowing application. It is, IMO, the ultimate true sleeper cam.

The Stealth I would be best for lesser exhaust systems and/or people not wanting to shift high to get the most of their cam.

Either should idle and drive about the same.

Colonel where would you shift your car now with the Stealth II cam? ALso where would the Stealth I can be shifted? I will have this on my second LS1. It will be a setup similar to yours with Kook's Headers and Borla catback with the PowerPlate system from QTP. Which would you go with I or II or maybe the 02 LS6 cam? I want best power and driveability.

Colonel, got any ideas for the ultimate sleeper cam in an MTI 427 superstroker?

Colonel

Snake, I haven't done any track testing yet (only street testing with Autotap and LS1Edit) but from looking at the dynosheets, and considering the gearing of the tranny and the observed shift extension of my converter, I think the all-out best drag shift points for this cam (with my exact setup) to be an actual (as opposed to merely selected) shift of ~6800. This is not to say that the cam won't work great being shifted at 6300-6500, it will, but I think it has just a little left in it by shifting it higher. I tend to believe in higher shift points for my personal use than many people and I should point out that MTI would NOT recommend you shifting so high as I dare to do and I probably wouldn't recommend it either. It's not worth the increased risk for the possible small gain for most people. I also believe that a converter with a higher shift extension would lower the optimum shift point a bit. Part of what I'm trying to do with the high shift point is to increase the shift extension of my relatively tight 3500 stall.

I think you can knock off about 200 RPM with the SS1. I'm just taking my best guess. I have no way to know for sure.

Levi, try an X1 on a 116 LSA.

I've got a couple clips of Thunder Racing's sleeper cam on the dyno. Unfortunately with the cutout closed, I didn't start recording before the car was "off idle," but with the cutout open it gives you even more of an idea of how subtle this cam is.

Cutout closed

And I know it's pretty rich, I've got the fuel pressure bumped up a little for the juice. This cam has worked VERY well on the bottle.

Cutout open

My driving impressions of this cam? It's basically like stock. With Thunder's tuning, it has absolutely NO compromises when compared to a stock cam, other than some valvetrain noise due to the steep ramps on the lobes.

What did you dyno with the cutout and w/o the cutout?

Thanks for the video, very impressive!

I would imagine the LS6 sounds just like the LS1 cam.

Thanks for the compliment.

I can't remember exactly what the SAE corrected numbers were, but I want to say they were about 7rwhp lower than my actual numbers. The actual numbers with an unlocked converter were 381rwhp with the cutout closed, and 390rwhp with it open. This was also through a 12 bolt with 3.73 gears, as well as TR6 plugs, so I'm sure it could make more power if I had it set up for N/A performance.

Ok, I like that cam you have,smokinv8, what cam was it again? oh and would it need tuning? right now all the mods I have are in sig how much rwhp would I be looking at with that cam?

It's the Thunder Racing "Old Man" cam. I went to their site just now to see what it was that they had called it on their site, and it looks like they're running a special on them right now.

I would say to get the most out of the cam, yes, you would need tuning. It's hard for me to say how well it would run without a tune though. And for how much rwhp you'll make with it, there's no way for me to know. A safe guess would be around 350-380rwhp.
