Hmm, the Comp Camp XFI VSR stage 2 (what brenspeed is calling stage 3) gets 34 (brenspeed got a little more but their test car had a few more bolt ons than the comp test car) ...so I'm pretty skeptical about those hotrod numbers. If that is true then sweet. I would want to see a dyno chart before buying to make sure they don't lose power on the low end. I'm very paranoid about that.
Comp Cams provides three dyno charts for NSR, VSR and SPR. The SPR are the only ones that don't lose on the low and gain 48 high-end. But I'm sure they're the most expensive option.
Right now I'm personally almost completely convinced on getting the SPR. Probably stage 2 since they have a "very rough idle" according to comp and gain more than stage 1 I'd reckon. But I'm not looking to do this anytime soon so it's likely I'll change my mind yet again (seems to be a never ending trend ).

I think cost wise they are all about the same from comps site, 742 MSRP, and i think install would be the same basic cost with them all except the NSR cams. I didnt see where it said the SPR dont lose any low end, i did see where stage 1 was gains for torque and stage 2 is focused on the higher RPM HP.
I dont know, I am still completely undecided at this point

Those dyno graphs show the SPR does not lose any low end, unlike the others. Jim D'Amore also talks about on that page how he did not lose any low end power. He didn't say exactly that he used the SPR, but going by that dyno chart I'd assume he was using the SPRs.

That sounds pretty sweet. Are those the same stage 3 comps that Brenspeed sells?
I'm starting to get confused now. What brenspeed is calling stage 3 is actually stage 2 according to Comp Camps (see the comp cams 3-valve link above). I checked and the part number (127300) and grind numbers (XE261H-15) match. Well mostly, the cams on comp's site says -15.5.
Also, the "stage 3" from the above video sounds a lot more lopey than what I see on youtube called stage 4. I have no idea what the stage 4 is since comp cams does not mention that.
I'm going to send Brenspeed an email about this stage number thing.
It is confusing, I had to read Comp's updated website from your link to figure it out. My how things are changing.
My Stage IIIs XE261-H are part number 127300, now a year later called Stage II. I got the Comp springs part number 26113-24 and steel retainers part number 700-24. Hope that helps.

A lot of the gains seen are very dependent on mods, and more specifically, the tune. You have to be careful about tunes because you can tune for max hp/trq and have a quirky car on the street. There are compromises for the street and track.
When I added the cams I went from 300/319 (hp/trq) to 323/309. That's with a C&L cold air kit, BBK shorties, Bassani catted x-pipe, and Mac mufflers already installed. It got me a 12.87 at the track, but the car was just a dog out of the hole, at least at the track. It felt fine on the street compared to other cars.
I came across a real sweet deal on JBA LTs and o/r h-pipe, and installed those and had it retuned recently. I went from 323/309 to my present 348/332. Think about it--had I put the LTs on the car prior to the cams and new tune, I would have probably seen 30+ HP gain, which is what they are showing on their chart, and note the similar mods. So draw your own conclusions.
For me, the car is more than a handful on the street, and tomorrow I see if I can start working my ETs down towards the magic 12.00 NA...

That's with BBK headers, Bassani catted x-pipe, and Mac muffler. I now have JBA longtubes and off road h-pipe (same Macs) but never got around to making a video yet...

the black stang with the white hood has stage 3 comp cams wich sound completly diff then the stage 3 posted above but he said now they are called stage 2? these ones are not as lopey at all.
P.s anybody know if those stage 2 cams are good with a TT set up. I know they recomend a certain pair for f/I does it just mean s/c or turbo too?

The BBK shorty, Bassani xpipe and Mac muffler setup you hear on the video was an awesome, loud, in your face exhaust at any throttle setting. With the JBA longtubes and h-pipe, it actually got quieter at idle and normal throttle. At WOT the sound is very old school, but I have to open the windows now to hear my exhaust while cruising. Guess I shouldn't complain as the Mac muffler drone is completely gone! Note from outside the car it still sounds wicked--just the interior sound has changed dramatically.

What kind of mpg are you getting with cams? Im stuck between nitrous or cams. nitrous ill obviously get a few more hp but the bottle refills arent the cheapest. cams i wont have bottle refills but im worried about my mpg going down.

Mileage is dependent on the left foot. Before I hit the drag strip, I put in some gas and drive 50 miles on the interstate to the track and reset the MPG. I get 25-26 at 65mph. Driving around town with little highway, about 20mpg, UNLESS I put my foot in it. At the track, if I reset the MPG, I get a surprising 14-15mpg. I would have thought the solid right foot driving would have put me into the single digits, but the engine must still be running fairly efficiently. I have 4.10 gears by the way, and it gets the same gas mileage as my daily driver '97 Mustang GT vert, which has a cold air intake, Mac exhaust, and 3.73 gears (auto) and 80k on the speedo.

I shlould have said it more clear but i was referring to the cams. I wanted to know how the cams changed the sound at crusing and WOT speeds.. Also, I am deciding between bbk shorties or mac lt's but i want which ever will make the exhaust louder. You said the shorties were louder than the lt's? Thanks

Hey boss, did you only notice a difference in sound at idle or at crusing or wot speeds as well? Any louder at Wot or Crusin speeds?

The cams affected sound ONLY at idle with either exhaust combo, and that was a mild lope (more noticiable with the BBK shorty setup though). Definately deeper and louder at idle with the shorties and bassani catted x-pipe. The cams had no affect that I could tell at cruising or WOT--I think that's more dependent on the overall exhaust setup. At idle and mild cruise, the BBK shorty/bassani xpipe was louder. But at WOT, I have to say the LT setup is louder. Pick your poison...
