how bad are these suckers do they work .......i have a 4.8 with k&n and Hpp3 how much gain will i get with this thing........

 

8-12rwhp. Maybe .1sec. Worth $200 to me? Not a chance... I'd off the HPP3 for a real tune. Besides you'll have an annoying slight undercharge at idle unless you step up to a HO custom alt.

2¢

 

sweet and yeah i maybe in mind on getting another alt...

 

If you are considering e-fans and pulleys go for the 200A for sure. Undercharge at idle just pisses me off.

 

i just might.......what kind off dough are we talking about those 200A alt's

 

Hold onto your ***... about $250! They should make about 90-105A at idle with a 3:1 pulley ratio so being 25% under you are looking around 65-75A at idle.

 

thanks.........

 

Mine wasn't that bad really. It would hold a charge with the lights and fans on low. The capacitor I have would never drop below 12.6, 12.4 is what it sits at with the motor off.

They do make a nice noticeable gain in performance though. I never got any track times with mine installed, but I could feel it wrap up a lot quicker.
