VVT + VICS + Boost + MS3X = ??
2560r, forged bottom end, VVT head, MS3X EMS. Take a guess...
|
About 15-20 hp lower than the proper squaretop would've netted you
|
Only reason everybody is all over the squaretop is because they're made of unobtanium in the US.
|
No, only reason everyone is all over them is because its a direct bolt in, OEM quality, stock looking manifold with proven improvement in topend flow.
Anywho, to answer the OP: I'm guessing over 300 |
running ALLOFIT? hmm.. pump gas?
|
yes, fuel type is a huge variable here. which is it?

Pump gas (93). |
Depends if u want power at 6k rpm or 7k rpm.
VICs > square top at everything but redline. |
I'm going to guess... 292.5whp.

MX-5 Miata Forum VICS vs Flat top @ 8psi
|
That before or after the 4.2% correction? :P
|
290 at 6800
peak torque at 5000 100 hp at 2500 |

Possibly. |
Fixed it for you:

not bad. post plot
kinda expected more than 100@3k with a 2560 |
dyno chart plox?
325 ft/lbs is a fuckload |
wait wait
is this... THE 2560 RECORD? |
Not a 1.6, so its irrelevant :giggle:
|
I'm glad someone finally did this combination. Now, buy vlads squaretop and see what the change is.
awesome numbers, congrats. Post the freaking chart, this was on DIY's dyno? |

What would these numbers be on a Dynapack?

Agree on that. my big fat mother of turbo on a stock motor was able to make 100 hp at 3200.
Yes, these numbers would be on DIYAutotune Dynapack. Sorry Zabac and JayL, Flipside manifold fits, but the throttlebody didn't and the timeframe prevented modifying this combination to fit with everything. Old dyno: Thank you DIYAutotune for your support! Here are couple cellphone pictures with graph. |
And what does your locost weigh?
|
I needz 2560. Also, 230whp at 8psi with a stock 96 motor? Seems a bit optimistic, no?

A stock Miata makes under 100whp on our dyno. Your standard 12psi GT2560R FMII or BEGi S3 will make ~240 whp.
The straight exhaust and proper external wastegate on Heikki's locost allow the turbo to perform more efficiently than on a standard Miata. He's also .040 overbore, forged bottom end, valve springs, SUBs, etc etc. This is the first turbo VVT car on our dyno, and it's the highest power BP engine we've tuned to date. I wasn't sure how VICS and VVT would play together, but turning on VICS resulted in a 10ft lb improvement from 3600 up. |

Ben, what's your VVT map look like down there? |
there's nothing bad about that dyno plot AT ALL--except for being right-side-up maybe.
|
Yeah. Looks great. And I sold my squaretop. And ben probably still has his since he totally blew me off when I tried to buy his back in the day.
|
I would be interested to see the timing map for this.

No worries man, I'm just giving you a hard time. I ended up finding one anyway :)
|
Displacement? Is it a +1mm overbore?
Compression ratio? |
The MAP/RPM curve looks odd for a 2560 with a nice open exhaust. Mine (FM2, FM 3" exhaust, 2560, built engine, 99 head) makes 200kpa by 3350 RPM, whereas that graph shows 3700.
It is a 2560, right? Not a typo for a 2860? --Ian |

Compression ratio? Wiseco pistons with 8.8 compression ratio after decking and adjusting the squish and compression ratio. turbo info on my for sale ad: The compressor has GARRET A/R 60 M24 1-1 on the casting. The bearing housing has HJ 01 06J 14411-69F00 466541-1 Turbine housing has Garret 2 turbine inlet flange is 72 mm x 45 mm with holes for 10 mm studs. T25. https://www.miataturbo.net/miata-par...ops-etc-69843/ Same log manifold made from weld-els used in this setup. |
any head work?

Trying to avoid high rpm float/7500 rpm harmonics issues with lighter weight followers and heavier springs. The Supertech valves are heavier than stock. The way the power curve is, I should not spend any time above 7000 unless it is short straight between turns and I can avoid shifting twice. |
Was VVT tuned in the spoolup area? (3000-4000 RPM)
|
At peak torque he's making 75 ft-lbs per liter per atmo of MAP.
That's much higher than I've seen on Dynapacks. My initial reaction is the dyno settings read higher than usual. |
I hope same trend of optimistic results will happen on timing system in Hillclimb :)
We shall see over the weekend. |
I made virtually same torque at about 270-280kpa.
But I have a stock head and my torque stayed flat till 7000rpm. |
Thank you DIY Autotune for good tune and even help on troubleshooting at the site.
This motor took the "King of The Hill" from Dragon hillclimb against some very impressive machinery, including couple Mitsubishi Evos, Lancia Evoluzione, Can Am McLaren, Datsun 240s etc. 72 cars in total. |
Wow congrats. Very nice
|
Vroom vroom!
|
Nice. What was up with the missed shifts? Need new shifter bushings or better engine mounts? I used to always stick my car into 5th when fast shifting the 2-3 shift with stock mounts. Not anymore with the awr mounts.
|
would daily.
|
holy road surface. looks like some pavement patches almost put you into the guard rail.
|
wall of torque from 4000-7000 rpm, jeez.
Even if the Dynapack is reading a bit high (Church Dyno settings?) it's still pretty impressive. |

If wrx, that's about average, not low. |
:rofl:
|
Has anyone else seen 75 ft-lbs per liter per 101 kPa on a Dynapack?
What makes it more dubious is the boost is a bit outside the max efficiency island of the GT2560. |

What I was insinuating is the Church's dynapack in SoCal is notorious for being the most "optimistic" dynapack in the country. Our dynapack tends to read ever so slightly lower than the dynojets in the area, however that dataset (cars that have run on both) is pretty small. What I was trying to say, is even if the dyno does read a little high, the torque from 4000-7000rpm is impressive. Whether or not it's 280ft-lbs or 310 ft-lbs according to different dynos doesn't really interest me, how fast that set-up would be in a fully trimmed miata, let alone a locost, does. :inout: Anyway, I should get back to installing a turbo in miata, all of these dyno plots get me excited... |

Nope, never did. I wasn't trying to comment on the dyno really.

Who the heck puts a stand alone on a stockish wrx? Thats who rom raider is for. No knocking on you guys but if given the option to tune with the stock ecu thats where I'm going unless the build is beyond the scope of what is possible to do on the stock ecu.
