05-10 GT Steeda Underdrive Pulleys Before and After Dyno and Track Numbers

[iceguyb14]

Made a video about the underdrive pulleys I had on my 2010. They definitely provided some solid gains and I never made a video about them like I should have so I figured why not now lol. 05-10 guys with the 4.6 who don't have them should seriously consider them. I gained 9whp and 8wtq on the same dyno 45 minutes apart which isn't bad for the $220 pulleys. And at the track my ET came down over a tenth and my mph went up almost 2mph.

Anyway check out the video!

EDIT: Also should mention I didn't have any negative effects from the pulleys either. Car still drove like normal, had cold A/C, power steering felt the same, and the alternator worked fine.

thanks man! Good info.

damn 1/10th and 2mph in the 1/8, that is some solid gains.

What other mods did you have before adding the pulleys?

Hey would underdrive pulleys be ok with a shaker 500 radio system?

Didn't affect my 1000w shaker.

I have Steeda pullies, shaker 500, and DR cams with the idle set at 650RPMs and dont have a single issue.

I had charging issues due to having the UDP's along with a PA Performance alternator. Apparently the pulley on the alternator is underdriven. Switched out to a different alternator pulley and whammo, no more charging issues.

No charging issues here shaker500, power errything, bout 3 years with the pulleys.

 

[Infamous05]

No charging issues here either.

Sorry for the late response. Was just concerned cause I'm still an automotive noob when it comes to car electrical systems and UDP.

Let's hope you're not really supercharged lol.
