pdexta, you will probably 60 just as hard as the 5.0 if you had skinnies and slicks. Maybe better.

I think you did pretty well considering his tire and gear setup.

Because a 400kpa one is more accurate

250kpa sensor:
MPX4250AP - FREESCALE SEMICONDUCTOR - IC, PRESSURE SENSOR, 20 TO 250KPA | Newark

700kpa sensor:
MPX5700AP - FREESCALE SEMICONDUCTOR - IC, PRESSURE SENSOR, 15 TO 700KPA | Newark

And Scott, just for you:
MPX5999D - FREESCALE SEMICONDUCTOR - IC, PRESSURE SENSOR, 0 TO 1000KPA | Newark

Just JB weld a nipple fitting to it.

I lied, it's $16.

buy two and a 1K resistor, a .22uF and .1uF cap and you can run baro.

MPX5700AP Freescale Semiconductor | MPX5700AP-ND | DigiKey

the MPX4250AP is accurate within 1%, the MPX7000AP within 2.5%. Good enough for me, so long as it's consistent.

I'm pretty confident that I could severely screw something up by trying to swap out a map sensor. I'm better off with the 250kpa sensor anyway, I need something to stop me from turning it up more.

Dude you are doing it wrong.

250hp miata is the fastest thing on earth. Not a 350hp miata. That is just too much.
