OK, Well I had posted up step by step instructions on how to do this but I guess I closed the window before posting. So here is just a Quick review. This wont take you long at all total time 1 hour or so if you know how the belts go on the pulleys. Very easy mod. Note: The crankshaft pulley came off by hand without a pulley puller and I had an impact guy for the pulley bolt.

Review:
When driving down the road I can tell the engine was less stressed. The real test was to floor it. So I did and the car came alive! 1st gear is useless (see other post for vid) There was defiantly some power free-ed with this pulley.

Specs:
Stock Pulley 4.5lbs
OBX Pulley 1.0LBS

Verdict:

$80 OBX pulley. Worth the money!! GO DO IT!
$225 RRM's Pulley. Still worth the money go do it!!












First start up video

Last night and this morning when starting up the car from it being cold it had a slight miss. Not sure if its related but it was not doing this yesterday or the day before. But it goes away after the car warms up.
Sounds good... but a miss fire? any CEL? could it be the nspp?

Nice oil leak!

Changing the accessory drive pulley is not going to cause a misfire. Maybe there is an issue with the new spark plugs you installed or something happened during installation.

im not hating or anything but is the power really noticeable? because i know most of the people say it is noticeable after they do small performance mods but in reality its just their personal feel after the performance mod was added.. but it looks awesome though
NO u can really feel this one. Even my g/f said something about my car seeming quicker and she doesnt know anything about cars or what i do to it. lol

Might take the Hi-Scan and scope the CKP and CMP paterns together with OE pulley and the OBX... reason is crankshaft harmonics,,, the OE has rubber ring and pulley to dampen crank oscillations.. the 1 piece does not, so the CKP might be fuzzy input to PCM..

Did you claim in previous post somewhere you was a tech at 1 time and tuner ... :grin:

OBD-II abbreviations :

CKP = Crankshaft Position

CMP = Camshaft Position

Just installed my obx pulley. Pretty ez install 1hr including setup and cleanup. I didn't notice any gains in first yet becus of the nspp, I'm burning rubber all of first with my 225s (planning on buying 255s to grab the road with no spinning). But I do notice when it downshifts in D the engine revs up noticably  quicker than with the oem pulley.
