I am going to add a Elec Water pump along with a ASP or SLP Crank Pully? What will I gain RWHP by going with a pullys

I already did research on the EWP & it seems I will gain 4 RWHP & 5lbs of TQ

What RWHP from one of these Pullys?

thanks guys!

i gained 25 horses with a lid and a pulley but i think the mod is more for how fast your motor will rev now......it was like night and day for me

Do you or anyone have any actual dyno proven numbers from a before & after when you added your pully or read any articals on how much you gain RWHP on a A4 Car?

I dont know about an A4, but I did it on my M6 car didnt really feel much of a difference my mods are in my sig, im not sure how it would be on a stock car.
But anyways I went from 417 to cleaning my air filter and putting on a asp u/d pulley and adding a * of timing and I got 427 so I dont have any real proven numbers by just adding the u/d pulley.

I gained 0 RWHP by adding a Pulley. Helped a tad in the 60' though. Roughhammer from years ago tested it as well and gained nothing to the wheels. I have been wondering who else has done this to because I keep hearing people say, oh, if you add a pulley you can get another 10 RWHP. I don't believe it, lol...Maybe a couple can be had IMO.

So the UD pully is a waste of money & will gain me no RWHP?

it will make it rev faster and thats always good i say it was 2 bills well spent.... and no i dont have a graph but i put down 325/ 348 with that a lid a pulley and a flowmaster with the stock y set up so those are decent numbers and i know that a lid and a crap master didnt give me that much

I definately think it's worth it for the gains you get in the 60' alone. It may get you a couple HP along with it.

I would like to see some others tests to see if mine and a couple others are the norm or if someone else has actual back to back test with no other mods show better HP gains. I have read articles in the past showing 10 rwhp gains with crank and Alt underdrive pulleys, but I sure didn't see it on mine. Mine was same day same dyno an hour apart.

would say it is at least worth 5rwhp...assuming you are talking 25%

I have an A4 and put on a Powerbond/SLP pulley. I didn't feel ****! I didn't get before or after dynos because, quite frankly, I got it used for really cheap and didn't care if I gained anything or not. Quicker rev? Yes. Lower current from alternator? Hell yes... I think I may have to increase the entire idle RPM table by 100. Stock is 550 RPM in Drive and 650 RPM in Park/Neutral.

Don't ask why I bought it not caring for any gains... it was on my list. lol
