#1476 of 1908 Top end speed by motorhead1 May 07, 2006 (10:00 am)
I tried my 1991 Corvette out on a stretch of road that is about 3k long and not any traffic to speak of the other day just to see how fast it would go. I noticed in Overdrive at about 135 it seemed to shift up and quit pulling very hard. I guess it shifted into OD, so the next run I left it in Drive and it did better but I was meeting some traffic so I slowed down. So I guess the best thing to do for top speed is leave it in Drive with an auto trans, what do you guys think? Replies to this message: starrow68 (May 07, 2006 7:58 pm)

Replying to: motorhead1 (May 07, 2006 10:00 am) From discussion with people on the C5 6sp, the top end is in 5th gear not 6th so I'm guessing that you found the same issue in the auto. The air pressure drag at that speed seems to exceed the ability of OD to provide acceleration. Stay safe and remember that birds and rabbits at those speeds are big missles.
#1478 of 1908 Back from Indy by bigmike5 May 10, 2006 (10:39 am)
Ah, what a great weekend, as I cruised up to Indy for opening day ceremonies, and got to run a lap on the track with 90 Vettes and the Pace car. 3 abreast in 30 rows, trying to keep good spacing and covered down. A memorable day in beautiful 70 degree weather. I just hope some of the promo shots that were taken are made available. My passenger shot some Sony tape, and I got a few digital still shots. Conti posted 2 and Dan did on his Indy site too. A really classy event, done up right by the Chevy and Indy folks and the Circle City Corvette Club. It was a "Corvette Day."

#1480 of 1908 ZO6 aftermarket air intakes by vettever May 15, 2006 (2:54 am)
I have a 2002 ZO6. I had a twin tube intake from a my 99 hardtop and would like to know if it will do anything for the ZO6 performance. It looks to me that GM has put a bigger intake on the ZO6 already. The company that manufactures the twin tube said the one from my 99 will fit (with a differante coupler the sell) and improve the performance on my ZO6. What do you guys think?

Replying to: vettever (May 15, 2006 2:54 am) Given the results of dyno's on the "cable tie" modification for the Z06, I would say you money is better spent else where. In addition, "other than" factory oem air filters do not filter as well. Oiled cotton media also increases the likelihood of getting mineral oil on VERY sensitive MAF parts which can cause your MAF to give false readings and or malfunction.   The factory designed air filter housing is really designed to meet or exceed the snow "prophalatic test: i.e. to prevent snow ingestion thereby increasing the chance of hydro lock.   Keep in mind the after market versions are NOT designed with snow prophalatics in mind.   So IF one does not need the snow prophalatics of the original design, a few options are: drill more holes in the cover to increase surface area, remove the cover all together and "cable tie" the air filter to the frame.

Replying to: vettever (May 15, 2006 2:54 am) If that is the only mod you are doing, then you will see very small improvement. However, if you are doing further mods, headers, exhaust, ecu mods than a freer intake is a must. As for damage to the engine, most aftermarket systems aren't oiled like the old K&N filters. MAF damage is unlikely. So is weather damage. I think everyone has more sense than to drive a Z06, or any other Vette in the snow! The biggest issue is heat soak. Esp here in the southwest. Alot of "cold air" systems just pull in air from under the hood, air that is already quite hot. If you are in traffic alot, the exposed filter will tend to pull in hotter air from under the hood. The Z06 has a better cold air intake than the regular C5's do, so this shouldn't be as bad.
#1483 of 1908 Balky Reverse Gear by bhill2 May 17, 2006 (10:48 am)
I have a '03 6-speed that sometimes does not want to engage reverse. By that I mean that when shifted into reverse the gears don't actually engage, and if I then release the clutch it chatters and goes nowhere. A second try usually gets it in. I can get around the problem by holding the shifter in reverse position as I start to let out the clutch; the gears then engage and reverse acts normally. Has anyone else had this problem?

#1485 of 1908 Building my Vette Vert next week by ultraman19 May 17, 2006 (2:23 pm)
I have a build date of May 22,2006. How many days does it take to construct a corvette?    Approximately, how long after next week will the car arrive?(OKC.)   I always purchase GMPP Extended Coverage.Usually, I can get a lower rate than the GMPP MSRP on the coverage, but this time they are not negotiating. ( 84 months/70,000 miles with $100 deductible for $2740). Does anyone know of dependable,equal or superior, coverage for less money?   I got a 3LT, Z51, 6sp. for $50,780. I thought it was a good deal, was it?   I have never owned a convertible, any do's or don'ts? Advice?   Thanks!! Replies to this message: starrow68 (May 18, 2006 6:41 pm)
