Just swapped the Main drive pulley for an Underdrive Pulley from my buddy. Here's a pic of the different. The idle RPM jumped from about 450 to 600 and then went down after a few min once the computer re calibrated?

 

Did you seen any gain from the underdrive?

 

I honestly haven't driven it yet. Been in the hospital with my wife. However something cool did just show in the mail!

 

Wow that looks fricken nice!!!!!

 

Sorry to hear that hope she's doing well!!

 

Very nice blazer and you have done a ton of work to it. I just bought my son a 2000 LS blazer. Looks like I need to start going over it more.

 

Nice job

 

Plugs, wires, and underdrive has been installed. I forgot to log in since I finished that. Low end performance is WAY better. I have noticed a jump off the line for sure.

On another note, I may move and I am considering selling it. What do you guys think I could get?

 

In April, I picked up this Blazer from musclemasterflex and agreed to keep making it the best it could be.

Since he did such an awesome job, there hasn't been anything really pressing to do. However, the motivation is getting there...

First on the list:

1. UCA - Left/Right
2. Pitman/Idler
3. Brakes -- all around

Granted, there isn't anything sexy in that list, but between the work MMF has done and these 3 items, the front end will be almost completely new.

On the sexy item list --

1. Bull Bar
2. Rigid Industries -- 10" hybrid light bar / 2 amber SR-Q1 Driving lights
3. Yakima Roof rack

Since time is an issue, I've farmed out the first list and should be completed by Friday. The second list will be done over the next month, or so.

I'll start posting updates and, of course, posting pics.
