Once you've bought all the big power gain parts they're good to gain 5-10 HP with. Add them to the MSD coils list.
ok thanks on that answer ,i was just wondering about them,and the cost was worth it or not
so red your saying it's worth it ??? cause I have all bolt ons pretty much besides an intake manifold and under drive pulleys.
were did you get them at, and how much were they, let me know thanks
do underdrives let it rev faster
Ya i want to get a set of these so any info would be appreciated
id love the msd coil packs but they are like 800$! i bough UD pullies for my truck but didnt have a before and after but id say it goes good...
as in you noticed something outa it?
Greg is right about the coilpacks--but not the pulleys. Guys---get pulleys. I had the MSD coil packs on my truck a few years ago and it didn't do anything! The UD pulleys made a big difference! I get better mpgs, more volts on the alt., and more power. After I threw them on, I went for a test drive and did a 2-1 kickdown and spun them--I used to not be able to break traction on a 2-1 downkick on concrete before. But I could once the pulleys were on. RPMoutlet sells some.
