C4 1993 Convertible Vette

[dan101]

I have looked all over the internet and have not found the specs on 0-60, 1/4 and top speeds for the convertable model. Does anybody have any idea? I also wanted to know if the digtal speedometer will stop at a certain speed per settings from the factory?

Is there any way I can move the water pump so it won't leak on to the....

Thanks.

Mine does 13.75 on the 1/4 with 3.73 gears and cold air induction,power pulleys and minor add-ons.....is that any good?...:cool

Find out the answers to most of your questions here:

http://www.corvetteactioncenter.com/specs/1993/index.html The "Production and Performance" and "Specifications" links will have your answers. The "factory" 1/4 times are pretty slow. A well-tuned motor and a set of drag radials should get consistent 13.5's at about 105-108. Of course reaction time and some skill helps. 12's are doable with a few mods.

The digital speedo should read to 255 as the CCM is an 8-bit processor. The car is capable of 160MPH speeds but will take a pretty long run to get there. I was able to get my 92 vert to hit 160 just briefly while going down a very gradual hill.

It would be pretty hard to move the water pump as the factory oump is a direct drive by the camshaft. A small shaft connects the front of the cam to the pump. There is an electric pump conversion by Meziere you can use as a replacement for the stock pump but as far as a remote pump, that would be pretty difficult. I ckeck my pump every few months by sticking a finger under the pump housing to check for any signs of leakage.

The 95 ad later Opti's had a vacuum line running into the cap that kept moisture out. You can install it but it requires a new 95 and later cap and making a few mods to the housing and you have to install a tee for a vacuum line.

Thanks that was really helpful, Do you think I can the car up to the 170-180s mph range?

The 90-95 ZR-1's were easily capable of 175 + top speed and that was with a HP rating of 375 and 405 in the later cars and it probably a conservative rating. You would need some pretty serious mods to reach that sort of speed with an LT-1 based motor. Figure around 400-450HP and you would need a stout tranny to take the HP and torque. The coupe would be a better cholce for that speed simply for the added strength and aerodynamics of the rear.
