Went up from a 120mm to 125mm pulley on the crankshaft to up the boost a bit. Was rewarded with 30 more rwhp.

Interesting, were these custom made pieces or from a different year/model engine?

What's the blower RPM?

Tom @ FFS makes bolt on 6-rib pulleys in a variety of diameters off the shelf. These are just his parts.

Crank pulley is now 125mm diameter, the SC pulley is 3.125" (79.375mm). Doing the math, that looks like circumferences of 392.7mm for the crank and 249.4mm for the SC. So, 1.575 ratio. 8000 RPM redline for the crank = ~12600 RPMs on the SC.

Ban for supercharging.

A: Turbocharging.

A: Supercharging.

(Ban for universal counterstatements) :D

Nice curve.
How much boost?

codingparadox 07-02-2012 05:25 PM
It seems to peak out around 18.5ish. It's hard to tell exactly. I don't know if it's something to do with having two many things off one small vacuum line, or if it's because a twin screw gives boost in such discrete packeted chunks, but the boost level on datalogs (and the analog boost gauge in the car) fluctuates by like 1.5ish psi in either direction.

WOW.

How about posting your setup instead of a dyno plot without a single clue on what it takes to get there.

Gotta say though, your plot is very impressive.

I just forwardededed this to the internet police. Consequences will never be the same.

In before ban.

Im also curious about how you accomplished this. As well as the associated cost.

Can you show your datalogs?

Post #56 on here (https://www.miataturbo.net/random-su...e3/) has more general details, but the full details are on my wiki (Main Page - DestinationSSM).

I've attached a pic of the datalog zoomed in on one of the later pulls and also a zip file of the full datalog if you want to look at it in AEMLog.

Oh my you need a MAP filter, badly.

I didn't even know that was a real thing. It just seemed like something that would be useful. :)

Any suggestions? Some quick googling isn't yielding much. Is it a homebrew type thing, or do you just use like one of the little inline tiny fuel filter thingies?
