Hey guys.

You bastards make me want a miata, worse than before. Id want to build something simple around 200whp. Im curious what type of performance I could expect from a 200whp turbo miata. I know alot will depend on turbo selection due to its influence on power band. So obviously Im not looking for an exact answer. Just your personal experience.

Id like to know what type of 1/4 mile trap speeds you would expect to see from a 200whp, street trim NA miata?

Also if your personal car has more or less hp, I wouldnt mind knowing your trap speed and info on your setup.

 

A buddy of mine had a MSM with a few bolt ons / mods. I think he was running somewhere in the low 14's not sure about the trap speeds he was seeing though.

 

200rwhp in an NA6 will destroy any stock subaru youve ever been in.

And since when was any subaru stock? They are the new civic

 

Ive never been in a stock subi, or even raced a stock one, **** Ive never seen a stock subi.

Seriously though the only subarus I have experience with are the old slow as **** ones.

Normally run around with a slightly more domestic crowd, a lil experience with miatas and some hondas and toyotas here and there.

I ran a 230whp subaru wrx one time, thing was quick for what it was, he said he had drug higher hp wrx, because most owners just up the boost first and he said they are faster if you do intake exhaust mods first, even though they will dyno a lil lower. Dont know how right he was. Hung pretty well with a 300hp tC though.

 

200whp Miata will trap ~100mph.

 

Running 14's wont beat any stock subaru out there, let alone if you did win, it would hardly be considered "destroyed"

 

Im talking a roll here.

NA6 with 200rwhp..
200rwhp and 1000kg including driver

Stock 2011 WRX STI
175awhp and 1600kg including driver


My atmo na6 beats non STI wrxs easily. Its not stock mind you..

Dann

 

I dont want to argue with you, but I wouldn't believe your naturally aspirated miata taking any wrx that is stock from a roll unless you are spraying.

Also, the 2011 sti has 305 HP, where do you figure that 305 translates to 175 at the wheels?

 

Go put one of those triple the diffs, twice as many CVs, and half a dozen times as much rotating mass, 305 flywheel HP cars on a dyno and find out.

My NA6 is completely stripped (not even any windows, except windscreen) and has 275 degree cams, 10.5:1 compression, 6 speed, 4.1 torsen, E85, COPS, etc etc.
Yes it does beat wrxs.

Dann

 

An AWD drivetrain will usually lose between 25% and 35% between the flywheel and the wheels. There's a lot of mass to be rotated. That's going to be somewhere between 200 and 230 horsepowers actually reaching the ground. So he's off by a bit, but not much. If a WRX with driver, passenger, and fuel weighs in around 3200lb and makes 220hp, that's 14.5 lb/hp. If his Miata's making 150hp and weighs around 2200lb with driver and fuel, that's 14.6 lb/hp. So I'd say his claims are feasible.

Edit: Stock bugeyes WRXs were rated with 227hp at the flywheel. That's between 150 and 170hp at the ground. So they could have as much as 18 lb/hp.

 

hp to weight isnt always accurate. STis normally trap between 103-105. If a 200whp miata normally traps around 100, a 150hp miata will get drug by an STi.

 

I ran my car last weekend and trapped 101mph. No idea what it's making at the wheels but based on weight & trap a few online HP calculators suggest somewhere in the 170whp area. 12psi on a big 16g with conservative timing.

A few weeks prior I ran my friend with a basically stock Evo8 (had 272 cams, nothing else) from a 25mph roll and had him by a car at 90. Arguably the cams hurt him down low. This was on a couple more pounds of boost, before my clutch started looking at early retirement.

 

This thread ******* sucks.

Just look around this forum and you will find all the timeslip info you want.

Same goes for subie forums.

**** this conjecture.

 

Right. But for the purposes of raw acceleration conjecture, when you're talking from a roll, traction isn't an issue, and aerodynamic drag differences are negligible.

 

Nitrodann I hate to break this to you, but I highly doubt your n/a miata beating wrx's story, unless they are some poorly running tired cars driven terribly. There is no way an n/a miata, regardless of bolt ons, will be beating a properly running, well driven wrx.

at 200whp a miata is quick, not fast. its quick enough to take down your average wrx and possibly bone stock sti. a wrx with sti bolt on goodies and a stage2 sti both will trap in the 106-110 range easy and you'll need about 240whp to take those down in a miata.

 

he didnt say n/a, he said na6.

 

For whatever it's worth, my stock motor 1993 with a greddy mani/turbo, fmic, MS, etc... went a SHADE under 105 at about 12 psi

Not sure if that helps, but that's some actual data relevant to the question.

 

Yes he did

 

Yes but hp/weight is based off peak hp, which doesnt take into account the actual shape of the powerband (area under the curve), and gearing, or even trans setup. Ive seen some low powered but high stalled cars destroy higher hp cars. A stalled auto ***** a manual at drag racing.

Just saying Ive seen cars that according to hp/weight should win, get walked big time.
