Just ordered a supercharger...

[Mosca]

For my Miata. I held off for 4 years, I just couldn't hold off any longer.

Woohoo! So how much HP and torque will it add? Any complications, or will it be a pretty simple bolt on?

Shoulda gotten a snail instead

I thought turbos were big for miatas. My neighbor has 2 turbo miatas, they are pretty sweet.

[Mosca]

Turbos are big, but superchargers are affordable. $2395, bolt-on (and an extra $200 for the Bipes Boost Timer). And turbos are mucho upgradeable, but I just want "Miata plus", no-fiddling driveable reliable horsepower.

Stock rwhp = about 109, w/SC = about 162. (From a typical dyno run, can be found anywhere on the 'net)

Stock torque = about 102, w/SC = about 150.

All numbers measured at the wheels; stock hp and torque #s are like, 142/130, or something like that.

Currently, I have a header/freeflow cat/ hp exhaust/muffler, so I'm looking to be about 170-175 rwhp, including the optional boost timing control unit (not used in the above hp/torque figures). And, the kit I'm getting includes a different pulley set for "an extra 20-25 hp over the standard kit!" I figure with everyone being optimistic, I would be around 185 to 190 rwhp, so the truth will probably be around 170 (185 minus 15%, plus the exhaust and BT unit not accounted for in the original estimate).

It should definitely be "Miata Plus".

And, the unit is visually appealing under the hood, as well; I mean, this is Autopia, the place where these things matter.

Did you order the Jackson Racing one?

[Mosca]

Yup, the JR.

I've had a supercharger on my Tacoma for the better part of a year now. TRD sells a very nice simple bolt-on supercharger for the V6 in the Tacoma. It bumps flywheel HP from 190 to 265, and torque to about 260.

The only problem is that it leans out the air/fuel mixture a little too much and you get low-rpm ping (predetonation). I've tried the cheap fixes (2-stage cooler spark plugs and a 160 degree thermostat) -- these have helped, but the ping is still there under certain conditions. The real solutions are bigger injectors, bigger fuel pump, and a piggy-back computer of some sort. But I really don't want to go there $$$ !

The supercharger makes my truck fairly fast, considering my big ole 31 inch tires and heavy-duty suspension. It just doesn't corner very well. Have fun with your supercharged Miata. I sometimes wish I had a little fast car to drive around!

I came so close to ordering a neuspeed charger for my car, but then I lost my job and found all that money I had been saving to be very welcome not to send off to mastercard
Oh well, I can live a naturally aspirated life for a few more months...

[Jeremy]

Sounds fun! My friend has a turbo Miata that is pretty darn fast. Fast in the straights, corners, everywhere.

Mosca,

Sounds excellent. Will you need a new ECU, or remaping done, or will the stock ECU work?

[Mosca]

Everything remains stock except for a piggyback boost timing control unit that retards the timing incrementally as boost rises. That's one of the things I like about the JR; simple. Not as high-horsepower as most, but not high-strung, either.
