Default M45 w/megasquirt dyno sheet/video

Hi,
I just got a megasquirt installed to go with my M45 and took it to the dyno for some fine tuning and dyno numbers.

Just wanted to share my numbers. The video pretty much says it all...
Feel free to ask if u got any questions...

143HP AND 133 TQ

looks like it would be a pleasure to drive, just a nice little bump to the tq curve.

Seriously, that car looks so damn clean....Got some more pics for us?

The M45's can be great fun. I was able to get mine to just under 170whp and I had a blast autocrossing that setup.

Man, your car looks a LOT like mine.

That's a great torque curve for DD and autox.

I was always worried about adding the load of a SC to the small-nose crankshaft. One of the main reasons I went turbo. Do you still have a small-nose, or have you moved on from that issue?

Ever make it up to MSR-C? I'd love to see your car.

Yes i know not a big bump in power but enough for my needs for now, its a blast to drive, instant power mid corner on demand

Small-nose crank still there... im sure there are tons of info on how to "deal" with this problem but if u could narrow it down to one option what would it be to "fix" this? i kinda have the mentality that if it goes i'll just get a 1.8...

And no i havent gone to MSR, ive wanted to go though...
and thanks

This is the latest pics i have until i can detail it and take some proper pics:

170 is quite a bit.. im guessing you had injectors, fuel pump, smaller pulley to pull this off? if so which injectors because this is the next engine step i want to do, but for now, after this i am planning on getting my 21 yo suspension caught up.

I did the Locktite thing on mine. That was about 50K miles ago (I'm about due to swap the timing belt again). Cheap and easy to do whenever you change your TB.

Love the picture under the trailer.

oscar: I am going through a rebuild of my M45 right now as well, adding a MS to it and looking to get msq files to get me in the ballpark. Any chance you could send me yours to take a look at? Thanks.

Thanks
I used the MR 300 Raydot Mirror. I would look a little harder if done all over again since once you tighten these you cant adjust them. So u kinda have to get it right the first time.

I also have a 1.6 with the M45 blower (Silverstone as well ) Mine made 140 hp with AFPR and JR Boost/Timing retard unit. Granted, the Dynodynamics dynamometer is said to read 10%~15% lower than a Dynojet.
The charts show the before and after the supercharger installation.





I want to go with the MSpnp to see what I can get powerwise and to optimize my fuel delivery/use.

I know that I'm going to have to get injectors and I was looking at the Mazda #195500-2150, 326cc (Probe turbo/B2600 truck) injectors. I found some in the used parts for as little a $50 but who knows if they are the right ones? I found a website where they can be purchased for $253 (reconditioned). I don't know if this is a good idea or not.

I would love to hear some suggestions or ideas about this too....

If you are under 7lb of boost (I assume) you could just use Supra injectors, 305cc, which are direct plug and play...

My blower makes 9 psi. I have been told I need 320cc injectors. The Mazda #195500-2150, 326cc are supposed to be plug and play as well (assuming I use an EMS of some sort). I'm thinking MS pnp....

First of all nice looking car!! it looks great all around! what side skirts are those?

And yes, thats the main reason why i went with the MS, not as much to get more power but just to keep the SC under full control an not have to worry about engine mismanagement or knocking, which in the heat it did alot of...

Wow you are running 9psi with stock injectors? and stock fuel pump?
I thought my injectors were pretty much 100% duty cycle, i didnt know they could handle more psi.

Next step for me down the road after i mess with suspension is to do fuel pump, injectors and then be able to add a smaller pulley to get around 10psi mark, im really happy with the amount of power right now though, it will do for a while.

Thanks for the compliment Oscar. Those side skirts are from RSpeed and I like them a lot.

I'm running stock 1.8 injectors. They are 15% larger than the stock 1.6 injectors. Also, I am running the AFPR which allows them to run a lot more fuel. At 96 psi and 6 lb of boost they will deliver 396cc. Take a look at this link. Now, if you are not running larger injectors or an AFPR with your system, you cannot make very much power and risk engine damage. Do you have an AFPR?

If you do not have an AFPR you must hurry and get some 320cc injectors. Don't worry about the fuel pump. The stock pump is quite sufficient for the HP you will make. This explains why your power output is modest from a intercooled SC with MS ems.... I would expect to see around 160 whp or better from a car like yours (unless the dyno reads very low)

I thought about going with 1.8 injectors but figured if im going to upgrade might as well upgrade once and get bigger ones.
I do have a AFPR, its a BEGI unit which is a old one and came with the car, but it works good enough i think.

What are your afr's at WOT? seems like mine could be leaned out a bit more to get more power, im averaging 12 at wot.

I can't remember off hand but if you look in the pictures of the Dyno sheets I posted you can see them. They are very rich.
A/Fs in the 12's is supposed to be pretty good from what I hear, but I don't know enough to opine intelligently.
Do not waste time and money with 1.8 injectors since you have the MS. Just go with 320cc and ditch the AFPR
