Under Drive Pulleys...?

SS_Firehawk · 08-30-2012, 01:35 PM

Two pulley set. This is also with CAI installed at the same time. This explains the bump in power at high RPM's. the 10whp average everywhere else is from the pulleys

So u went on the dyno after u installed a CAI and the pullies?

SS_Firehawk · 08-30-2012, 09:11 PM

Yes

Spent $372 for the CAI and $214 for pulley and belt. The bang for buck ratio is strong. I had gotten a deal on both. Probably won't find a deal that sweet anymore, but if someone spent another $100-$200 for the combo, it's still a great buy. It's showing 10whp all the way up, and up to 16whp at 7000-7500... After I installed Long tube headers, HFC, exhaust, and no tuning.

I went with the Stillen lightened and underdrive, as I trust their quality over the other options. Just wish it was available black anodized.

Dyno gains were 6hp 9tq peak and overall quicker revving.

Look man, it's common knowledge in this forum that cold air intakes have no benefit and show negligible gains below 6500 rpm. As I've stated, the delta increases exactly at that RPM on the dyno charts. You've posted 2600 times, you can't be ignorant of this. I know exactly where the pulleys made power.... EVERYWHERE. And I know where the CAI's made power, over 6.5k. I really was not trying to spell this out.

i have to agree.anytime you can remove unsprung weight (pullies,wheels ect),power increase is guaranteed and is something the ecu CANNOT adjust for !

You don't know at all where the pulley made power because you installed it at the same time as your CAI. Your claim means nothing.

You must mean rotating mass, and I agree with you there.

Unsprung weight is attached to the suspension and not supported by the springs.

wow even in hotter weather! Thanks for the dyno chart upload +rep

Joepro · 10-18-2012, 07:44 PM

I put my stillen pulley on today, its been raining so I cannot romp on it, but throttle response seems improved. I am not sure why people find this hard, with the right tools ots a snap, 1/2 drive with 2 foot + breaker bar and a large prybar to hold the pulley and some elbow grease puts this on in little to no time. Granted I did mine on a lift, it took me all but 20 minutes from lifting to putting down. for 165 bucks, and if I get 5 whp, quite worth it IMO.

VDC_OFF · 10-19-2012, 09:55 AM

How hard is it to align it when installing. Not sure what im looking for.

Not an issue, it's keyed. Remove belt and pulley, install pulley and belt.

I did not need a puller either, it wiggled off as did my 350z with 70k at the time.
