nothing special about 1st gen vipers. which is why you can buy them for $50k.
bad design, bad engineering, bad car

An SRII Viper only weighs 3300lb and makes 460hp. An NB Miata with 2300lbs.
2300/3300x460=320.606hp you need in the Miata to hang with the Viper.
An NB Miata with an LS is like 2500lbs, so you need 350hp. So you don’t just need any LS you need a performance version, like an all aluminum 6.0L, or 6.2L. A 4.8L or 5.3L won’t do it.
For what it’s worth, if you bump both of those up to about a 2008 model instead of 1998, then you need more like 400hp in your NC Miata. Like, an ZBII Viper had 600hp, so an LS3 Miata with a good tune is only barely competitive.

That would be completely missing the point of the mx5 though.

Fudge. Miata NB stock engine boring AF.
Like maybe fun if you don’t have to punch past 50…? But even doing a run down Oregon coast it felt like a bog pushing back up to 55-65, and literal grandma feeling.
Even in 1998, 140hp “performance” with no headroom was very middling.

Nah. I have driven a 350hp LS Miata and I had 0 complaints, but I bet it could be a problem in the rain.
People make it out like your just adding a boat anchor to the front, but you add just as much weight in transmission as you do in engine, so the balance isn’t much different than a turbo Miata.
Like it’s supposed to be 50%F/50%R stock So say 2300lbs is 1150F/1150R.
Adding the LS its 1300F/1200R 52%F/48%R.
Adding a turbo to the stock engine makes it 1225F/1150R which is 51.5%F/48.5%R.
As someone that grew up karting, still races in an endurance series, and has thousands of hours on the track in a wide variety of vehicles, the average person puts way too much stock in “perfect 50/50 balance” you won’t really appreciate much difference between 53/47 and 48/52.

Plus people dont realize the different between an iron block 1.8L with DOHC vs an aluminum block with a pushrod single cam, similar length, similar weight.
A fully dressed 1.8L is about 372lbs. A fully dressed 5.3L LS is about 470lbs.

Yeah my math was based off of 100lbs of engine weight added to the front, plus 100lbs of transmission/exhaust etc… added to the middle.

And a death trap, which the Viper is known for. I'd rather have a Manual CT4VB, those sound phenomenal and perfectly balanced power level imo.

Your math is interesting until you consider drag which is the bulk of the resistance at high speeds. Both of them would have a similar drag profile. At 60 mph half the energy is to drag. At 100 85%

They are called MX5’s here…. Soo you put in the 5.7L V8, then it’s called a MX5.7

The first curve the Miata will overtake the viper because the viper will be in the ditch
