Video : Funcool's Cogged 112 Maggie!
Had several requests for a video about my cogged rear pulley system on my 112 Maggie so we put one together last night.
As the video will mention, I've experienced the driver’s side head separating from the block with 20+lbs of boost. I've heard several experienced tuners mention that 18lbs is the safe limit for 5-bolt heads, and I can confirm that.
I'm not sure if I want to risk a dyno at full throttle. I'm past the safe limit of a 5-bolt head, I'm planning on changing the pulley so I'm at a safer boost level of about 15lbs. soon.
For those of you who don't know, here's my dyno with the overdrive 8-rib system I had before.
My best was about 15lbs, then the boost would slip away to 12lbs at the top rpm's.
Give you a rough idea what she should be making now . . . .

And here's the video of the current cogged system.

My best was about 15lbs, then the boost would slip away to 10lbs at the top rpm's.

Is it me or is your boost gauge deceiving? With 20+lbs of boost and probably over 800 ft-lbs of torque I would've thought your tires would be screaming for mercy. I understand you have nitto drag radials, but I would imagine you could overpower them especially at lower speeds.

Funcool,
You probably have a bunch of pulleys around from your experimenting, why not put a 3.4 on the front of the maggie and see where that gets you? Awesome boost instantly, great video thanks!

He could be at 25 psi for all we know .. That guage was pegged 
The only way to find out if the car was actually making more power and not just heating the air would be to dyno test funcoolo.
The question is ... Who but who will you have tune it

I have a 3.2, 2.7 and 2.4 8-rib pullies. The 2.4 is on the car right now and I'm going to try the 2.7 next. Today went by Champion motors and got a bigger alky jet from my buddy Rob. I'm going to make the car more rich.

It was good seeing you and Tony at Champion Motors! Rob has a big selection of parts in stock and can provide you with almost anything instantly. I would try the 2.7 pulley and get your car on the dyno and dial it in properly monitoring air fuel, no guessing.

My good friend Tony was dyno tunning his 427ci novi car at Champion motor. Arun the ''doctor'' was doing his magic and made 720rwh with 12lbs of boost!!! This was done a 3.5 blower pulley, low timming and very fat A/F ratio!!!!!!!!!!!!!!! I just hope that Tony does not put on a 3.0 pulley and make my life harder!!
