    "Seat of the Pants" performance boost

    Hi Guys - I can't speak to turbulence, but the system outflows a modded Z06 airbox lid, and here is how I know. When a member of corvetteforum said he was using a flow bench to test the flow of CAI setups, I sent him a brand new twin-ram to test - Here is the result of that test -...

    Wanted: 2003 Z06 factory H-Pipe

    Hi Blue - Check with LG motorsports - They always have a big pile of em they will send you for the shipping cost. You might find an installer closer to you that does header installs and they will have the same pile of stock exhaust components - just a thought. best regards - mqqn

    Z06 headers any HP gain?

    Hi Pseudomind - I put LG Long tube pro's on my Z, and coupled with a tune I picked up 33 rwhp. My car does not have cats, but I retained the stock Ti catback. Using the metal matrix high flow cats will only cost you 3-5 rwhp, so it is still a good bump in ponies - but it is the increase in...

    Headers and cats

    Hi F15over - It would not defeat the purpose, but you would be leaving a little HP on the table as opposed to going with high-flow aftermarket cats. The LG headers come with an x-pipe. I opted for the LG Pros and no cats. best regards - mqqn

    Zo6 rear end noise

    Hi alan - Perhaps a change of diff oil is in order? I changed mine out in my Z at 40k - although I was not hearing chatter. It was pretty noticeable in my formula Firebirds - you knew when the diff was chattering.... best regards - mqqn

    Changing lug nuts???

    Hi kingman - If they are the factory oem kind that screw onto the outer threads of the oem lugnuts, I would use jut your hand and the socket and an extension - no wrench - Tighten them until you feel a click. That gets them on tight enough to keep kids from removing them but not so much as...

    Chrome lug nuts??

    Hi Alan - Like Mr. Lucky said - you can get a torque wrench at Harbor Frieght for $20 or less (Tire rack has them too). The torque value is 100 foot pounds - but it is best to step them down. I usually tighten them to 50, then 75, then 100 in a "star" pattern (i.e. tighten one then tighten...

    Chrome lug nuts??

    Hi Alan - I get it now (duh :duh ) You just want to buy chrome caps to replace the grey ones. Sometime in March 2002 GM stopped putting on the lugs with the removable beauty covers and started installing chrome plated lugnuts. I prefer the chrome ones over the two piece ones, but I...

    Chrome lug nuts??

    Hi Kingman - Nuts you can get anywhere - a forum vendor, GM , autozone...... I wrapped my 19mm mid-depth 6 point socket with black electrical tape (3m super 33) and that keeps me from bunging up the wheels. Be careful and you won't have any problems. best regards - mqqn

    AC Problem on driver's side C-5.

    Hi billroth - Remove your battery and battery tray and look down inside the cavity. Examine all the vacuum lines in that location - they control your heating/cooling ductwork. One of my friends had an issue similar to yours - the ducts did not see to blow enough air - it was cold (not like...

    Newbie C5 questions...

    Hi Konrad - I have both a 99 coupe with 3:15 and a4, and a 2002 Z06 (mn12 6 speed and 3:42) They both get about 19mpg around town - but on the roadm the Z gets a solid 29 at 75-80, and the a4 coupe gets 26 or just a tad better. The coupe is easier to drive calmly - and the Z makes your...

    Valvoline Instand Oil Change Warning

    Hi raidoman - I am not defending the service place here, just giving a little 411. Flushing the trans with the flushing machine will clean the filter (according to GM anyway - call em and ask). That and the fact that you get all of the fluid out instead of just MOST of it with a drain an...

    breaks lock when 88 get to temp

    Hi topguesser - Could a component of your anti-lock brake system be touching an exhaust manifold or other heat source and be experiencing a thermal failure? I am not versed in C4 at all - just thinking about what could cause the symtoms you describe. If I understand the symptoms...

    What Would You Do?

    Hi redvet - I personally would dump the shark as fast as I could and buy the newer c5 or c5.5 gen vette (c6 is not truly a new gen IMO). Your question by its makeup trys to convince the reader to keep the shark. What you are asking is should you let your wife decide what enthusiast vehicle...
