Dyno Day

The motivation of this post is twofold: first, to find out the baseline of the car's performance prior to installation of an aftermarket intercooler (the Nisei looks like the main contender at this point), since the last dyno was done more than a year ago. Second, to silence the critics who do not believe the car is mostly stock but is capable of sub 2'40"s at Sepang.

Here's the "mod list":

1) MoTeC M800
2) Upgraded fuel system (800cc injectors, Walbro fuel pump, SARD FPR)
3) AC Delco boost solenoid controlled by ECU
4) DIY intake, DIY downpipe, no cat, SuperSprint catback exhaust
5) Ogura Carbon-Carbon clutch assembly
6) Cusco front and rear anti-roll bars
7) Bridgestone RE070 tires
8) Ferodo DS2500 brake pads
9) Goodridge SS braided brake lines

Everything else is stock, as in "supplied by factory". This means stock cams, stock turbo (TD05HRA), stock bottom end, so on and so forth.

Put the car on a local Dynapack, results (at wheels) were: 378 Nm @ 3800, 270 PS @ 6100. For the benefit of Americans, this would be 278 lb-ft @ 3800, 266 whp @ 6100.

Boost was at 1.35 bar between 3600 to 5100, where it went up to 1.5 bar until 5750, and went down to 1.4 held till 7000 RPM redline. Total of 4 pulls, all done in 4th gear.

Granted that different dynos produce different outputs, my car is a 2003 Evo 8 with the smaller turbo housing and no MIVEC, but still compares favorably to Shiv's Evo 9 tunes which are said to do about 285 lb-ft/285 whp (with boost at 1.6 bar peak, holding at 1.5 bar and tapering to 1.3 at redline).
