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. |

A stock 03 Imprezza just made 180 whp. Still think the dyno reads high?
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.
