Before/After Cam Swap Dyno Results

[NOMIEZVR4]

WOW what a coincidence..exactly 1 year later I'm posting a new VD plot for my car! Same temperature outside too as last year...

Anyways, exactly 1 year ago I posted my VD results for my car at wastegate boost which can be found here:
Dyno chart for my 19T VR-4 - 3000GT/Stealth International Message Center

So at WG boost last year I dynoed 262whp with the following mods:
Built Motor/heads
JDM Gear
Fidanza Flywheel/Clutchmasters stage 3 clutch
MTC Ported 19T's--WRX converted 13T's running 6lbs of boost
Walbro 255 hotwired
Megan Downpipe/ebay 02 housings
running a stock VR4 rom on a flashed SL ecu...thanks Monochrome!



Stock injectors, 93 pump, stock catback, ABS/AWS/emissions delete..

1 year later my setup has changed only slightly...I now have an EVO MAF/IPS Quadtip and most importantly Cams. Webcam 150e regrinds w/shims and crower valvesprings. These are also known DR Street cams as I've been told. I unscrewed my Hallman MBC all the way out and was able to go as low as 7lbs. 1lb difference from last year. I also shimmed my wastegate actuators but I'm not sure if they are the reason why its now only going to 7lbs.

So the result...


Driving Impression: The car runs great...on stock cams it really ran out of steam at 7k even though I was revving out to 8k...with the cams now, however, there is a surge of power as the tach sweeps past 5k and the car pulls hard to 8000rpms. More than the power, is the sound. I've always been a sucker for a nice exhaust note...hence the IPS exhaust..with the combination of the cams and exhaust, the 6g72 sounds beautiful at WOT....at idle it sounds good too.. I'll get you guys some clips...

Oh yea just wanted to mention, I did NOT degree the cams nor do I have cam gears. The dyno plot is just a reflection of drop-in cams. I'll be putting my bigger injectors back in sometime soon and converting to e85 when I get a chance to up the boost. For the hell of it, I upped to boost on stock injectors to max them out and was able to get the following on 11lbs boost stock maps...

I'm about to sell mine for dirt cheap, making me re-think the decision.

Good stuff!
