    Uhh boy. GM underrates these cars. Fact is they all (stripped down Z or WS6 or Vette) have about 350hp. They underrate the WS6 and they underrate the Z even more. Use your math to figure out how a car (Z28) will put down 300hp to the rear wheels but only have 310 at the flywheel. Jeez, this is old news. If you believe what GM says about em why did they rate the 1/4 mile times the same for a Z and a WS6? They said 13.9et for both. Shouldn't the WS6 be faster with that extra 15 hp?

    so why is it I pulled a 13.75 @ 104 in my 98 Z with all-weathers and 2.73s when I added the weight of SFCs and STB but my only functional mods were a descreened MAF, EGR tube cut-off, lid, Free Ram Air and K&N!
    THEN: 98 Z28 A4 2.73 FRA STB SFCs LCA Relocators LowSprings DAPHR SLPBilsteins Descr.MAF EGRCut-off Lid Eradispeeds - Daily Driver includ. 3 yrs on the German Autobahn!
    NOW: '02 WS6 M6 LOTB BMR STB, SLP bolt-in SFCs, !spare/jack, !rearseat, SLP lid, Battery Relocation

    I went to Home Depot and picked up some 3/8" automotive weather strip (I think a 4 foot roll) and installed around the hood opening; I checked the seal fit by opening the headlights and you can see it seal between the hood and the air box, also after installing the foam tape strip, you can hear a sucking sound now from the ram air hood opening that you could not hear before the tape was installed. Although my car is a Firehawk not a WS-6 you could do the same (open head lights) and see how much clearence there is between the hood and the front of the air box opening and judge the space between them and pick up the size you need. Hope this helps... Oh, I also installed a Holley Powershot (less cost than a K&N) resuable air filter, and I like how it fits as complaired a K&N filter also w/o the use of grease like the K&N requires.

    And if you look at the dino from the cars bone stock any Ls1 will make more than either of those figures(at the motor). Gmhightechperformance says they are all closer to 350. GM did not want to advertise a 30K car had the same HP as theor own 45K vette, this is nothing new companies have been doing it since muscle cars first hit the street. But like most of these arguments, all is made clear at the light.

    Sure I'll try but it will be a few days or a week? as I work 12 hour days and I have the dreaded dial-up at home, and yesterday the fuel pump on the '98 Chev PU (daily driver) took it's last squirt, list price from dealership was $570.

    1998 Trans Am WS6 'Vert

    C&D tested a '99 SS 'vert 6M and a '99 30th T/A WS6 'vert 6M, same day, same track, same drivers. The 1/4-mi and 0-60 times were indistinguisable between the 2 cars, BUT the SS topped out at 158MPH while the WS6 hit the speed limiter at 162MPH. They both have "ram air" (or "cold air", whatever you want to call it), but these track results tell me that the WS6 intake is a tad more efficient at these high speeds, than the SS w/ it's intake located further back on the hood and longer tract to the air filter.

    Is the "ram air hood really functional"? Yes, BUT.........

    1) The primary benefit is cooler air into the engine due to short path to outside air
    2) The "ram air" effect (boost pressure in the intake manifold) isn't going to happen <100 MPH. So don't expect big improvements in your 1/4-mi ETs unless you are trapping 120+

    1999 WS6 Trans Am

    [QUOTE=I was thinking about cutting the redirecting plastic vanes out of the nostrils... and also using some rubber to seal the aribox to the hood. Has anyone done this or thought about doing it?[/QUOTE]


    Check out my pics in sig for seal, rainshields, BG TEF's etc. This is how GM should have done it had they not have to contend with all-weather driveability.

    Ram air? How bout this, as stated above, a sealed ram air hood is a really good CAI. All you are doing is introducing colder fresher air from in front of the car instead of warmer engine bay air, which is a good thing.

    As far as the WS6/SS having 15 more hp than a TA/Z28...read the fine print on that one. GM claims a "Freer flowing exhaust" 2.75 vs 2.5 as one of the reasons for the gains. Also as stated above, they all pretty much dyno within a few ponies of each other anyways
