Awesome results.

Again, driving this car was absolutely awesome. Very very very very quick. Would easily would have raped my GT3071 just by power under the curve. Would easily rape my s366 unless i did a like, 70mph roll race :p

Rolling burnout through third gear is a lot of fun too. I highly recommend this setup for getting groceries.

I am excite

Pumped! Now I have to find a reason to come out to DC...

Those are great numbers at only 24psi! Nicely done!

Holy BALLS! https://www.miataturbo.net/attachmen...ine=1350101423 Nice job mang!

NOW, WHERE IS THE VIDEO? WHY ARE MY EARS NOT BLEEDING FROM THE RAPE?!

What gears / tranny?

Car is actually very quiet. The muffler really muffles a lot.


5thgear in 6spd. 3.9 right lenny


I wana see what your turbo does at 40psi mr 8374 :p

Oh my god, that looks fantastic.
I wonder how long this car will last before something breaks. hahha

Please tell me more about that orange line coming off the breather. Where does it go, and details/ etc.

O_o

Looks photoshopped. The shadows are all wrong. Definitely fake.

Agreed. I'm calling BS on the entire thing. That shop looks sketchy and not reputable, like Sound Performance. Also, I noticed the location is not Greece, so let's be honest, it's really 240whp at best.

speaking of which, where is your butt buddy?

Don't wanna thread crap/drift too much. Short version: federal agent working out of LA, drives some big ass Mercedes to pull ho's, miata is being finished eventually.

Leonid, Faeballs, Mr.Ican'tmakeaproperworkingMS, we need vids pronto.

Holy fuck!

Yeah buddy!!

I'm going for 30-32PSI max. I better get my 575 crank power at that point!

Was somehow expecting a little more. Got 420whp on the GT3076 car, with the ignition retarded 5 degrees due to no water in the WI system and me not noticing on the final pulls. 5 degrees is like 40-50whp on this setup. Ok, that was at 29psi though.

So, in another news, IN SOVIET RUSSIA, BOOST TURNS UP YOU!

obviously seafoamed :drool:

well done Soviet, this is most impressive!

It goes to a catch can which is mounted on the passenger side firewall. It is a -12an line covered in fire sleeve.

Those numbers look amazing.

HoleeShitman strikes again.

I was going to drive over and meet up to this...but my 220rwhp is so slow i count make it. I went into reverse and cried.

I need to see what one of those turbos could do on a 1.6L...that's just crazy impressive.

Well that looks like fun!

Soviet is busy having victory secx with his harem so i will answer quesions in hus stead.

If you only make 550whp at that psi then there is zero hope for me to break 600 with my s366 at the same psi. Balls.


Yah. So.

Details on the three runs:

Run 1: Wastegate, 17psi
Run 2: 23psi
Run 3: 26psi, plus 2* timing

I think the car can hit 450hp on e85 and 10psi more :D. The little power taper up top could probably be flattened up with more timing in the last two columns.

Yus. after dyno, we went to some ------ry "car meet" because it just happened to be next door. Scott promised to show up - didn't. After that I spent time with le girlfriend and went to autox today. Just got home.

Car rapes face, turbine wheel didn't explode. Autocrossed at 300whp (wastegate pressure) Autocross is pointless in this car right now because it just spins wheels. Its a hoot but wears out tires quickly. So I'm going to stop autox. Problem solved.

Lars is correct, it's a -12AN line going to a catch can with a breather. It's always dry. I get vapor out of the catch can, that's about it. PCV hole is welded shut.

6 speed, 3.9 gears, 5th gear on dyno.

So has MT finally found the "HOLY GRAIL"?:D

And here's what everyone really cares about.

However, I don't think that chart fully represents EFR6258. Simply because back then I had very simplistic boost control (open-loop EBC with boost duty table that just had same duty % everywhere).

So here's an example of EFR6258 with my simplistic boost control vs EFR6758 on just wastegate - 17-18psi vs like 17psi peak on wastegate. 6258 clearly wins in spool.

And finally, closed-loop EBC vs wastegate on EFR6758. This clearly shows how superior closed-loop EBC is and why you'd be stupid to not run it.

24.5 vs 17psi, identical timing map on both runs.

holy sh

:drool:

That poor transmission, lol.

Pretty sure I'm at the limit of my drivetrain and I DO NOT want to play the expensive "lets stuff a drivetrain from another car into a miata" game.

Thats what I would expect.

Now put some cams in it.

How about I put some wiener in your puss?

Awesome numbers, congrats.

Fae said "stock crappy 1.8 head" is that a NA head? 99-00? 01+? I guess I need to go study your build thread, I want my car to be just like yours when it grows up.

Soviet is running a stock 94-97 1.8 head.

Actually its a 99-00 IIRC

Imagine the dyno chart with VVT. Faster spool. Better top end. :drool:

I wouldn't do anything for top end. But faster spool, most definitely

VVT head, porting and a turbo intake if he doesn't already have one. That spool is pretty badass though, not going to lie. If I only had 5k to throw down on my car...

turbo intake?

Frankly, the car drives amazingly as is. The only thing I'd want is longer gears and a higher redline.

I will know in a couple of months!

Short runners, big plenum, etc.

putting a short runner mani on this car would be incredibly stupid

we're all drooling at his torque under curve and you're suggesting he reduce it? lol

Yeah it's a 99-00 head I picked up from a junkyard. The only thing I did to it was machine the head surface flat.

I have a VVT head in garage and while sure, I may not necessary pick anything up from just having VVT vs 99 head - the purpose with the VVT head is to build/port it for a higher revlimiter and better flow.

I want a nice intake but its the lowest priority item right now. Gotpsi IM is close to $1000 and I'd rather spend that money on tires :party:

FTFY :giggle:

This would just get that much more crazy with VVT. If you had to guess and without becoming physically ill, how far into this build are you dollar wise?

Is the boost rising to redline? Just wondering what's keeping torque up as typically the stock manifold was "blamed" for torque drop post peak with rpm rise.

I'm very interested in this too. But then usually its not just torque drop that others experience. Its power drop too. This thing does neither

So with the VVT, are people actually noticing HP difference? I just don't understand why the factory didn't use it on the Speed Miata (Mazda hasn't always been known for good decisions, so this might've been another case!) My 99 head is ported for my engine and so on, but just for future since the engine will be rebuilt once a year at least anyways.

VVT does nothing past 3 or 4k rpm iirc
Just lowend/spool

this. I probably wouldn't change a thing as far as the IM is concerned... Has great spool for the turbo size and holds very well to redline.

Alright, basically where I won't be on the track! I just like to simplify the car as much as possible!

EBC holds boost to redline - flat like Keira Knightley. Addressing the torque drop in high rpm was most important to me. Here's the things I've changed:
- obviously bigger compressor wheel with different compressor map
- VICS works and activates at 5000
- magic timing map made by Faeflora, with timing ramping up about 6* from 5.5k to redline
- sacrificed a goat??

My reasoning for using VVT in future is not "VVT is magical" but "if I'm going to spend $$$ on a head, might as well be a VVT head"

I think I'm at $20k for everything including the car, and there's a good chunk of money in suspension/brakes/tires - non-turbo stuff, basically.

have you tuned the timing latency?

I'm on a 36-1T trigger wheel, what latency?

HAve you checked if the timing retards as the RPMs increase? should do it with the timing locked and using a timing light. This is part of the proceedure during initial setup.

Nope, haven't checked and already took off timing plastic plate thingy. Timing latency is only an issue if you're using a CAS for primary tach signal. Stretchy timing belt and all.
