Default Top end speed

Has anyone taken their s/c C5 to the Silver State Classic Challenge race in Nevada? Now that we have installed the KB bap, we are looking into attending one of these races. The last tune gave us 527.55 rwhp, and would be interesting if we can crack the 200 mph barrier.

Better make sure you have proper arrowdynamics on the car. Stock c5's start to lift at 160.

No but it is something Y2Kroadster and I have talked about doing. I don't think Nevada has E85 though, it sure would be nice to keep temps down though!

With the addition of the s/c and accessories, which add weight to the front of the car, it lowers the front which should improve aerodynamics. I have had our car to 172 mph and it was rock solid. Other than the s/c everything else is stock. The base C5 is more aero than the C5 Z06 because of the sloping back window.

Stock C5's do 172 from the factory and the ZO6 does into the 180's. I have never heard of a C5, ZO6 or not, start "lifting" at a high rate of speed. What is your source for this information?

Oh he's right, they lift hard over 165-170. It's tough to see in the video, but when we were in the 170's the car's nose was just about floating to the point that I had to stay on the crown of the road to keep it straight.

Damn really? Well I guess if I decide to run in this, I'll have to add a splitter and a rear wing huh?

Personal experiences. I got caught in a crosswind over a bridge and it put me in the next lane. Def a pucker moment. Un latch ur hood and see how long it takes for the hood to start rising from all the air pressure under hood. I know little tricks like lowering the nose more than the rear seem to help a bit.

Yeah I know lol...I NEVER magazine race but have heard of the Vette's actually living up to their claimed top speeds.

It sounds like I'll have to buy a splitter and a rear wing to keep the car down if I'm going to try the SSC.

BUT...I'm not sure if I want to beat on my car for that long...not sure how it would hold up...

I had a vented hood too, but suspension was basically stock.

Can you recommend a good splitter/wing combo that would keep the car planted past 200 MPH?

Call Katech or LG, they will point you in the right direction.

I have their C5 hood and it's well built in my opinion. Very light too.

For a modern well developed and aerodynamic car. Why on earth are they so unstable at speed ?

My car's a 30+ year old brick and feels totally stable even at 190-200mph.
