FWIW,
Following mods were performed on our bone-stock 2001 Cobra:
DiabloSport 4-bank chip
From day one I felt that the motor had a real conservative fuel setup on it. Kinda like the motor was leaning waaaaay out at WOT..... dying for more fuel. To help solve this, we installed the DiabloSport chip. Once you get the factory computer out from behind the passenger side kick panel, install is a breeze. Diablo gives you a pad of ScotchBrite abrasive pad for cleaning up the contacts on your computers' circuit board. After you scuff up the coating on the contacts, it's really just a matter of plugging up the harness of the chip to your circuit board and "Voila". The design of the Diablo allows you to "hide" the chip and its' innards inside your factory ECM box for a clean look....... (no wires hanging out, etc.). Then just replace the kick panel cover and you're done. (BTW, I neglected to mention that you need to be sure and disconnect your battery prior to removing your ECM box.) The chip really seemed to help the motor pull at higher RPMs. Throttle response feels better when you mash the pedal now, too.
Steeda Tri-Ax
I think enough good stuff has already been said about this one, so I'll only comment briefly. I, for one, LOVE the transmission noise it adds, too. Kinda sounds like the old IMSA GT transmissions you heard from the in-car cameras. A chimp can't miss third gear in this thing now !!
Steeda UDP's
I added these at the same time that I added the C&L MAF, so isolating which one gave me what gains took a little dyno checking. As it turns out, I netted 10 RWHP from them when all was said and done. I had the dealership install these and judging from what I observed, rates a "medium" on the backyard mechanic difficulty scale. Having a lift and the right tools (ie-impact wrench, breaker bar) at your disposal would definitely help. Word of warning: be extra sure you get the right set of pullies from Steeda, 'coz Ford changed the water pump pulley design mid-year in '01 and used two very different pulleys, and they're definitely not interchangeable.
C&L 80mm MAF
For those of you who may have not yet heard, I'm probably one of the biggest advocates for this thing on all of Stangnet. The difference in pull with the addition of the C&L was nothing short of incredible in my case. The '01 Cobras (in bone-stock trim) seemed to be gasping for air, particularly at higher RPMs. Well lemme tell 'ya what, this baby solved that problem for me BIG TIME. All of a sudden, the car felt like an asthmatic that just got a good blast of Primatene, pulling like a mofo on the top end. When we took it to the dyno, we made a pull with the C&L/K&N combo in place, then swapped the factory MAF and paper filter in and promptly lost a dyno-verified 13 RWHP on the second pull. 'Nuff said
The install of this things' a breeze too. Took all of 15 minutes.
FRPP Aluminum Driveshaft
I actually had this installed as a warranty replacement item when my Service Tech (God Bless Him) said he was feeling some drivetrain vibration at higher RPMs while test driving the car. All it cost me was the difference in price (about $40.00 installed). You don't really feel any gains from this mod, but just knowing that you're reducing the weight of parasitic drag on your drivetrain is a good thing........ especially for the price.
To date, we dyno at 299.0 RWHP/ 305.1 ft lbs torque.... or about 27 MORE RWHP after the mods shown. Haven't actually been back since the driveshaft install, but it's a safe bet I'm just a hair over 300 at the rear wheels now. We're also still running the factory Cobra exhaust setup for now, down to the tips. Probably a few extra ponies hiding in there if 'ya know where to look, but I'm honestly not in any real hurry to find out just yet. Maybe next spring.............
