    What is up with Corvette Clubs ?

    I vote for #3. The internet has become the best Corvette club one could ever want.

    Best way to get ATF back into auto trans

    or, just attach clear tubing to the spout on the ATF fluid bottle. Then just squeeze it.

    Nitrogen and Run Flat Tires

    O.K. Sometimes I'm slow to see that. :)

    Nitrogen and Run Flat Tires

    why would you do that? Ignition wires carry D.C. The failure of a stranded wire (where the surface of each individual strand starts to corrode - thus insulating one strand from the other - causing capacitive reactance - which will start to attenuate audio signals) only affects A.C. ... not...

    Nitrogen and Run Flat Tires

    I tried to read your link, but it wanted me to register. "Register" just to read a post ??? wouldn't it be more accurate to say "according to this particular source... there is no real benefit to usage of nitrogen."

    Proper RPM for launch....

    thanks. I was in dis-beilef too. So I ran again and got a 12.97. That night - all the best conditions were there. Track prep was excellent, air temp was in the 60's. I was geting all the launch I could get out of stock runflats and a stock TC. That was in the fall of 2004. Best I've done...

    Proper RPM for launch....

    I powerbrake launch @ 1300 to 1400 RPM in my A4. I can't hold it back at any higher RPM. Here's my best 1/4 time with the followign mods: *3.42 rear axle ratio (still using factory TC and tires) *Predator tune *Z06 titanium mufflers *Z06 airbox lid *K&N drop-in OEM filter

    New gears vs. engine mods

    here's my experience. When changing rear axle ratios in my C5, my biggest concern was traction. Although I had owned 1970's era muscle cars with 4 speed manuals, I got tired of shifting and sliding all over the road (when making a wrong throttle or gear choice). Nowdays, I prefer a...

    New gears vs. engine mods

    hear's a quick-n-dirty way to calculate C5 rpm changes when upgrading rear ratios: from 2.73 to 3.15 (add 15% to any given RPM) from 2.73 to 3.42 (add 25%) from 2.73 to 3.73 (add 37%) from 2.73 to 3.90 (add 43%) from 2.73 to 4.10 (add 50%) from 3.15 to 3.42 (add 8.6% to any given RPM) from...

    Rear Differential leaks

    ...for side plate seals ??? who told you that ?

    Rear Differential leaks

    that's crazy. You can buy the new style seal and anerobic sealer for under $35 and do it yourself. FYI: Carrier tranny center-shaft seal (A4): 24207010 $10.96 Seal Plate O-ring (A4): 12369456 List $10.75 aluminum 6" seal plate (A4): 12369457 List $51.00 The other seals are: 89047953...

    New gears vs. engine mods

    rear gear choice is personal. But many will tell you that with the A4 C5, the 3.42 is the best "all around" ratio. If you frequent the dragstrip weekly and a timeslip rules your life (and that is a great life to live)... then the 3.73 or 3.90 ratio and a high stall converter may be the better...

    C5 Coupe 1/4 mile speeds & times

    don't let me sound like I'm bashing the G-Tech or other similar devices. They're great for street practice and doing A-B comparisons (before mod - after mod). Though, I've run into too many Mustang and import owners bragging about a (too good to be true) 1/4 mile time... only to find out later...

    New gears vs. engine mods

    Head & cam gives the measureable HP improvement, but that only occurs at a narrow RPM range. I think one notices the improvement of gears more because the benefit is felt at all RPM's and in any gear (even overdrive). But for racing and 1/4 mile times... I'm sure the H&C & headers are the...

    C5 Coupe 1/4 mile speeds & times

    With my stock 2002 A4 and 3.15 rear ratio (only mod was the Z06 airbox lid), I was able to get consistent 13.3x powerbraking at 1300rpm. I wouldn't, though, brag about those G-Tech numbers BEFORE going to the track (and proving it). I've never met anyone that was able to duplicate the...

    Another Optima red top problem

    if you want that technology - but don't want to purchase the Optima brand... there is another mfgr: made by Exide.

    R&R Driver Rear Axel

    you will ????? I had this much off my 2002 and not one drop of diff fluid was removed: and it won't take this amount of disassembly to replace just one boot. to change the boot, there is no reason to get inside the carrier.
