1.6L miata with a stock head, turbo 2 rx7 drivetrain, 275 drag radial. 1.51 60' 6.96 @ 102 1/8th 10.74 @ 132 1/4

mph seems down for power

 

Well it makes like 150whp at 5000rpm, and 500 at 6000rpm, so seems legit. (<==Stolen Joke)

 

Hate all you want, but thats a low 60 foot for a miata.

Slow *** time and mph, but have to respect the launch.

 

Which happens by default when you stick an only technically street legal 275 tire on a car...

A miata with 500 rwhp should trap in the 140s.

 

If he wasn't granny shiftin........

 

Geez, this thing is crazy.

 

Crazy stupid.

 

I know its a guide but thats a big gap i just worked off a kerb weight of a NA miata ( i was playing with this calc flat out yesterday trying to find a combo for mine to drop my times)

 

His average HP between 5900-8500 RPM is about 440. That's the RPM that he'd be at after shifting from second to third. That average power is ideal because it was a dyno started below that, it does not account for the fact that he has to re-spool the large turbo every shift. He better be shifting at redline, because 5500-8500 is an average of 410 HP and 5100-8500 RPM is about 390 HP, any RPM wasted is BIG power left on the table. He would be below 5000 RPM from first to second gear, so that would certainly explain why his trap speeds and ET's aren't anywhere near a 500 HP estimation. Peak power doesn't doesn't tell it all.

 

So, to summarize, peaky power is great for dyno queen internet bragging but having a broader powerband or better matched gearing to narrow the needed powerband may be more beneficial to real world results. What is that the road racers say? Area under the curve?

 

Shoulda gone 1.8

 

I can't believe this POS thread is still going.

In all seriousness though, there's no way that head is "stock". I'm running 13psi an actual stock 1.6 head, and mine absolutely suffocates above 7k RPM.

 

"Stock" these days to the young'uns means "stock ports." It has springs and huge cams.

 

sounds bone stock to me

 

It has a Puerto Rico idle without the Puerto Rico performance.

 

I lol'd. So true.

 

I am a little disappointed no one threw in a "and pick up underaged girls" joke into this one

 

that's the "area under the curve" he was talking about

 

And is promptly smoked by a V8 with half the investment cost.

 

"Area under the age of consent?"
