Alllllllright, who built this here? (viper/2sk content)

KE=(1/2)MV^2, kinectic energy increases exponentially with velocity. Furthermore, now that the car can accelerate faster, it will need to be stopped more often, meaning the brakes need to shed heat faster.

Yeah, I get the kinetic energy thing...actually graduated from engineering a long while back.

Y'all live in a world where everything is always running on a track. And yeah...I get that I am posting on Grassroots MOTORSPORTS board, but still...

The limitations to stopping that car are going to be the rubber and heat dissipation. Heat dissipation on the street will be a non-factor. So, it should be just fine. Your squared factor in the equation is velocity, and Honda has already factored that in: ie they anticipated the car going 150 mph and gave it the brakes to stop. So all you have to worry about is the extra weight, and it is NOT exponential, so no different than a fat passenger. I personally would take my chances with the Honda brakes over some home brewed system that are sold with zero real world development time. And by home brewed I mean just about all of the aftermarket big brake kits sold.

That thing is not likely to ever see a track, and if it did, I would be surprised if it went any faster than it did with the stock engine; it might slip, slide and burn up the tires, but unless someone has really sorted the chassis,(doubt it) terminal velocities might not be any higher than with the Honda engine. The situation certainly can't be worse than say, stock Mustangs, and they still go on the track until they run out of brakes.

I see a street/show car that probably does not need brakes.

You mean the best Viper motor ever built.

Better bearings, cracked computer and 1000 hp just a credit card and some heads porting away.

I admit I like the GenIV stock much better.

Yeah bro and the original S2K made more than 100 hp per liter. Not that boat anchor

Youre right, needs a pro charger. Too.

I wonder what tires are on the wheels, and how good it handles with that heavy engine in the front. I get the impression that a shop did the swap for around 50 grand, maybe more.

not sure if it's the same car or not, but here's some build photos of an s2k with SRT10 engine....

It's possible that it's the same car. That has to be one of the worst, undramatic build threads for such a unique idea.

The issue here is not that the lap time won't be quicker, but that car will CERTAINLY be arriving at the braking zones with a lot more speed to scrub than a stock one. More extreme braking events per lap = more heat dissipated per lap.

Again...you are assuming that this car's main purpose is to be a track rat and that the chassis is able to allow for higher terminal velocities.

I see a street/show car that will never go near the limits of the stock S2000 brakes.

Bet the car as a lot more design issues that would put the brakes further down the concern list.

True, but I guess I default to drive it hard / drive it on the track when I look at most vehicles
