Rotrex size 100 pulley installed...what a difference!

Well as usual the mod bug is biting away so I decided to drop a pulley size on my DDMworks Rotrex setup and OMG what a difference with just a pulley change . Thanks Dave @ddmworks

I'm still rather new to the SS world, but not to forced induction by a long shot. I couldn't find hardly any threads on folks swapping pulleys out on here and given the MASSIVE lower end throttle response and extremely noticeable acceleration gain I don't know why more people aren't doing this?

6 5MM torx screws (Making sure to not spin the SC backwards I heard) and a 3/4 ratchet to loosen up the belt tensioner that's it. (5 min job max)

Am I missing something here because the other car communities that I have been a part of over the years jump all over pulley swaps on S/C applications?

Just curious that's all

P.S, yes I did clean up my bracket after snapping that pic

Thank you sir!

I saw those posts, but I only read where 2 people changed pulley sizes.

Since Bob's tune already has the calibration for the higher MAF signal it's a no brainer for me. I know a tank of bad gas or a 100+ degree day will be dangerous, but I have an AFR and Boost gauge to keep an eye on things. It's honestly like a whole new setup. Not trying to sling products here, but anyone with a Rotrex setup should really consider this mod!

Glad you are enjoying the new power, it is a lot of fun with that pulley!

Great seeing you at Maggie valley also, talk with you soon,

Dave

Likewise sir.

My Platinum AMEX is standing by for that engine

I will even throw in the wood box it came in (Very inside joke between Dave and I)

You mean like this?

OH YES!

Man that's good looking!

The 100 pulley was just to hold me over until I get a new block and cams. This is addicting!

Quote from Dave@DDMWorks

With the cams it is even more fun

SOLD!

When are we doing it ?

OH YEA!
