Nice. I would ditch the SS emblems though.

I'm in Georgetown, and I go to Nelson Performance. Only about 1 1/2 hours away in San Antonio. We are planning on meeting at San Antonio Raceway (1/4 mile track) tomorrow night. He will be there.

Have this posted on PT, but not getting much input. So I thought I would try the experts here. This is a question about the efficiency of a P1SC versus a D1SC. I know a S/C takes HP to make HP, and I believe the D1 is more efficient than a P1. I think the P1 is a radial design and the D1 is a spiral design, so does the D1 make more power at the same given boost level as a P1? So my theory is that with a D1 at 12 psi would yield more HP than a P1 at 12 psi. Is my thinking correct? If so, does the additional power come from the more efficient design, or it just takes less power to turn the D1? Or both? I am trying to weigh the pro's & con's of upgrading my P1 to a D1, and was thinking out loud about the performance increase, if any, of just making that change alone (with any tuning adjustments). Thanks in advance guys, S.C.

Seriously...no one???

are those keys hard to install? <{POST_SNAPBACK}> Not at all. Only special tool you need is a two jaw puller, which you can rent/borrow from O'Reileys or Autozone. About 45 minutes is all it took me.

Anyone?

Like the first post says...sold.

Good for about 2" drop on 1/2 torsion suspension. 2 months old. For sure works on Silverado SS, VHO. Maybe Tahoes too. Boxed up & ready to go. $35 shipped

Back up again. Come & get 'em!!!

Sale pending..

You'll love it. Gatorback that thing too!!

It is a P1SC. I am not going to put it on until I get it retuned. I want more, but don't want to instantly grenade it either. I might never put it on after the retune!! Just a few more weeks & I'll know for sure.

Bump for new price!

About 8000 miles on mine so far, no problems. I called RR to make me a custom 3.2, he said would be about $125-150. <{POST_SNAPBACK}> I have a 3.6 RR right now and hit 9 on a really cold day if I am lucky. What are you running for boost with a 3.2"? No dust around the pulley? What about belt size you are using with that 3.2" <{POST_SNAPBACK}> I am still running a 3.4 for now. I just upgraded to 60lb injectors, so the 3.2 will go on soon. I see about 11-12 psi with the 3.4 now. I do get some dusting, but it isn't bad at all. I run a 110.5 Gatorback.

Probably not unless you have an all out NA motor. Most people use them when going FI, just like I did.

SOLD!!!!

AC Delco Part # 12589867

Paid $42 new for it, don't need it. New in box, never installed. Only took it out to look at it. Ordered for a 2000 GMC 5.3L, might fit others too. $30 shipped & it's yours.

Thanks for rubbing it in.

You are wasting your time and money with the handhelds. <{POST_SNAPBACK}> Even with daiblo u are! I thought it was just as good! I guess I was wrong my bad. I feel like and idoit now I just bought one! <{POST_SNAPBACK}> Live and learn. Almost all of us have been burned by some type of mod. Mine was wasting money trying to make an exhaust. Ended up with Corsa. Would have saved a couple hundred bucks if I would have just bought it in the first place!!

HOWDY!!

Mine is sweet. Eliminates slip. I run it with the Gatorback belt.

I NEED a crank pulley for an '04 LQ9. I am not sure if other years/motors work.
