It took 14 ish psi to make that power on my setup. Holy crap.

So by now either something broke or he passed out from the acceleration.

He should have live streamed it. I'm going to do that when I dyno. (Which I just schedule for a Sunday...cough cough...Ed)

Hello? Jeff?

sooooo??? I want to know about allofit

Still alive and the car did not explode and pop like I was so nervously fretting about the entire time. I for some reason assumed that something would go wrong in my head so that if it did, I would have prepared myself for it.

Kyle, the tuner, started the car up and immediately said, "Your car has a misfire, can't do anything till we find out why."
-insert Jeff coldsweat

I was worried that my new COP harness was improperly wired even after testing the shit out of it. Then I was even more confused when he said it was cylinder #1, which I just barely replaced the coil on. Turns out that on my way down, the spark plug had cracked....shit. Luckily we tracked down some NGKs, gapped them, and started her up again, boom, perfect idle....thank god. Could have been much worse.

After that he spent an hour going through my settings and pulling everything in the proper direction. He got my EGO correction functioning perfectly, AFR and knock sensor protection running, and a shit load of other settings that weren't active, activated, and the car sounded soooooo good just idling. Have never once heard it that smooth.

After that he started doing long slow pulls getting my timing and fuel where he wanted it and steadying out my boost in 9/15/20 increments.

I understood what he was talking about, but due to baking at 3 am this morning I was a wreck, and didn't stand over his shoulder the entire time pestering him with questions. Just hung out with a Vegas friend and shot the shit while intermittently giggling like school girls at the sound of the motor.

Started at 4, got new spark plugs by 5, finished by 8:30, hung out for a bit, then drove home and arrived safe and sound at midnight. No updates due to me needing to get home before I crash figuratively and literally.

On I-15 on the way back a truck didn't like the fact that I was 4 car lengths behind him and brake checked me harder than I have ever been before. Not sure if he was pulling some insurance fraud stunt but I locked up hard on all 4 wheels and right as I was about to slam into him I saw the right lane was empty and fucking dived to the right of his bumper. I think I heard my front bumper give the edge of his bumper a small tap as I narrowly avoided totaling my car. He then proceeded to try to chase me but soon gave up after I floored it to 120 in 4th gear. That is one way to wake me up for the two hour drive!

I want to say I did something wrong, but I literally have no idea what could have provoked him. Thank goodness I didn't flat spot my tires when I locked up. I had to force myself to let go of the brakes so I didn't have a repeat with my Rivals.

This car though, this is what I envisioned back in 2013 when I bought the car. This car is perfect, I've attained automotive bliss. All it took was 1.5 years of hard work, an EFR turbo, and FAB9 giving me way too much of his time helping me piece everything for the turbo together. Seriously Bryan, I appreciate it so much. And to everyone else who helped, encouraged, and provoked me into burning more money than I originally would have on, decent parts, but not great parts.

Anyways, I'll stop my Oscar acceptance speech and just say 3rd gear is like teleporting now, I gave all the shop guys a ride, and all of us couldn't stop giggling. Unfortunately by that point I was too excited and tired to record some of our runs, but I plan I doing that tomorrow when I can actually see the officers of the law.

But we wanted results right? Those beautiful lines that we all look at and say, "damn, that is a nice line, maybe not a line off a hookers ass good, but damn"

He overlapped the 9/15/20 psi runs for me. We planned on doing an ALLOFIT run, but due to our shitty 91 octane, we decided to stop at 20psi, due to having to retard timing to prevent detonation from my shitty fuel, even though the graph showed ZERO signs of getting out of the efficiency island. He told me he could plop an easy 75hp with E85 on top of my 20psi run.

I forgot to ask for a boost plot as well, but I'll get that from him tomorrow.

I have nothing to compare this to off the top of my head, but FAB9's manifold and downpipe seem to be incredibly well paired with the EFR 6258. You want your car to feel supercharged? This is as close to that as I can imagine without compromising top end.

I'll upload some more video tomorrow but for now here is a video of him tuning a full 6th gear pull, and the 20psi pull that follows. Sorry I didn't get behind the car but I didn't want to get nailed by any aerial projectiles.

Holy fucking shit... This car would scare the shit out of me.

Very well done Jeff!

Time for an ABS swap! :)

Very nice dyno chart!

Properonis!

Sounds like a freaking jet. That's awesome.

Very, very nice Jeff! :bigtu:

This is with the 3 port EBC and only using the one port on the EWG, correct?

So this is a 99 head?

Can anyone explain why at the same RPM and the same boost pressure, my setup made 40 less HP but only 6 less lb ft? Why would that be? I've noticed that with several EFR dyno plots I've seen. Higher HP but not much more torque.

I thought that HP was a product of rpm and torque...so different dynos?

^that's what I thought as well. Doesn't make sense.

Dynos side by side:

Mine. Built MSM motor, GT2871R on Absurdflow mani on an AEM EMS4 at 20 psi:

Jeff's, Built motor with '99 head, EFR6258 on Fab9 manifold with MS3x.
https://www.miataturbo.net/attachmen...ine=1429227064

One thing that I always look for is what RPM does it hit target torque... And I am surprised that it took all the way until 4,200rpm to hit 200lb/ft. I know it could be any number of things, but I am just surprised being that so many people consider the turbo to feel so strong so early.

The street and how it drives is the most important thing, I am just surprised that we aren't seeing earlier torque onset. Ed's 2871 is hitting 200lb/ft at 2,800 and 250lb/ft at 3,200 rpm it seems. The reason I am so critical isn't that I am not impressed, I am just trying to weigh going to an EFR from my Precision 4828 when I build the motor and upgrade my manifold...

Nope both ports on the EWG are being used in this fashion.

99 head with active VICS

Not sure why it shows the delayed torque due to it not feeling that way while driving. It kicks hard and fast early in the rpm range. *shrugs* I'm totally happy with it. I think the most important thing for me is how linear the power is delivered. As the graph shows it just ramps on straight with no real dips. You can definitely feel that.

Your peak power happens at 6500RPM. Your torque at that point is ~250ft-lbs and dropping fast.

Jeff wound all the way to 7000RPM to find his peak power (actually, it doesn't look like he peaked, just let off at that point). He still had nearly 270ft-lbs at that engine speed.

So, Jeff's engine/turbo combination is pumping a bunch more air than yours. 40HP worth. But, he's not spooling nearly as quickly. Choose your poison.

Yeah I hate to say it, but torque peak is a little sad. The N/A NA VVT I just tuned hit 115ft/lbs at half the rpm it took jeff's to hit the same. VVT vs. VICs, but still.

I'll ask the tuner but I'm happy with it, oh well I'm kinda glad honestly, more controllable this way! ;)

Yeah don't get me wrong it looks fantastic, and I'm sure it's super controllable. Awesome results! I was just curious about the HP and Torque, but I think Rick answered that question. Your HP keeps going up because your torque keeps going up, unlike mine where my torque starts to die down (not quite sure why it would do that, either).

Thanks gents. The more you know, and all that.

Jeff are you going to Miatas at MRLS this year? I know Mobius isn't going to make it and his track spot will be available...
