Yes, rleete is right. I am in no way trying to be a dick, and you habe to understand the humor on this site. In fact, if you would like help from somebody as sophisticated as myself, I would be more than happy to help you.
Pretty much what we're saying is it sounds simple enough to just put a big pulley on and run 4 more pounds of boost than you're running, but that 4 more pounds of boost can do lots of damage. Especially because I'm pretty sure you have a power card or something which does not control timing at all, and it's a poor way to control fuel as well.
Please tell us more details about your setup. What kind of intercooler do you have? What size exhaust do you have? What are you using for a wideband?
When did you start moonlighting as a French hooker?
5psi on a MP62 kit, even off the shelf, is a little on the low side. You're probably running the default 95mm. For each larger larger crank pulley of 5mm, you're generally getting one extra psi of boost. Plan accordingly. 10 psi is roughly 200 rwhp on this kit, very repeatable results. You can still get different size pulleys from FastForwardSuperchargers.com.
Figure out what kind of fueling solution is being used by taking a pic of the stock ECU and whatever aftermarket card is patched in.
Sorry for late responses. Wanted to find out info on miata but life had other plans and I havent had time to do much besides new tires.

Murtaza. I wasn't feeling very creative with my gamertag, I wanted to get my name as the tag, but had to settle for the closest sounding one.

PS, stay far away from anyone who uses tems like "slap on this" or " Re-flash that".
Yea, after talking to a few of them I realized they're all about the turbos and think superchargers are stupid. But the guy who changed my tires at firestone used to own a "ubercharged" (as he described it) miata, and he offered to do cheap work on the side. Plus he made my brake and steering wheel noises disappear so I trust him lol

I need to just open the hood and measure the pulley size. The weird thing is, the previous owner had a dyno chart that showed 185whp, so with reaching 10 psi, I should see over 200whp?
Also, I wanted to ask you guys for recommendations for a good replacement supercharger belt? The firestone mechanic told me it looks worn out. I should've just asked him, but was in a rush

Find the number on the existing belt. Buy a Gates equivalent - auto parts store should be able to cross match numbers.
Lots of factors determine size. What tensioner, 4 or 6 rib, what size pulleys, etc.
Go here: Gates Racing Performance Micro-V® Belts if you need to know how to measure for a new belt.

I found these numbers on the belt, 1413ac and 76135s32. Dumb question, but which pulleys do i need to measure? If anyone could point to them (if visible in this pic) or where they should be behind the radiator. The one on the right measured 70mm
That number (1413ac) checks out as an 8 rib belt.
I'd take it to the parts store.
yea I think you found the same link I did. Maybe the previous owner cut his own belt or something. But I'll be taking it to autozone once I figure out how to remove it. Gon be fun.
Take a 3/8 ratchet (or 3/8 breaker bar), stick it in the square hole in the tensioner, rotate clockwise (or, you can stand over the drivers side fender and pull towards yourself) and slip the belt off one pulley.
It's easier than it sounds.
Pic from google images, and not a Miata...
Should give an idea, anyway..
So I got the car dyno'd last week, and it showed that the AFR was all over the place, and always above 12. And the boost was actually between 6-7 psi So the guy recommended I get a tune. And he suggested i go with haltech for ECU, since thats what he works on the most.
If I'm gonna spend the mula on a ECU and tune, might as well get new pulleys and injectors.
What do you guys recommend for ECU, and injectors. And what size pulleys would get me to 10-12 psi. Thanks in advance
For ECU, if you are going to pay someone else to tune it, you get what they are good with.
Injectors should be easy to find what we all recommend here.
For pullies, you have to go by the pressure ratio for a supercharger. So at 6-7psi, you are at a pressure ratio of 1.44, and you want to get to a pressure ratio of 1.82. So you need to increase the speed of the supercharger by 1.82/1.44 percent. Which comes out to 126%. So take your current pulley size and divide by 1.26.
This may not be exact, but will get you in the ballpark.

Yea that's what I was thinking, but haltech is so expensive. And i believe it has the stock pulley setup of 95/65mm but i will double check.

Haltech is cheaper than rebuilding your motor a time or five because it's not running well. If you want to tune the car yourself, get whatever ecu you'd like. If you'd like to utilize your tuner's services, get what they like.
