Magnacharger Radix boost results on stock kit

[CHarris]

Finally got around to installing a boost gauge yesterday and took the truck out for a couple of hard pulls to see what max boost is on the base H2 kit.

The only mods I have made are three 2-inch holes in the stock airbox bottom (still running stock filter - only 2800 miles on the truck) and a Magnaflow catback. Tuning is that provided with the kit. Pulley size is the 3.1 that was included with the supercharger.

Truck makes about 6.5 pounds of boost with 7 showing at the shift point. What is cool is that it offers up about 5 psi as soon as you hit the throttle.

I'm pretty happy. Now I need some dragstrip results.

Cory,
Is the gauge an option to the super charger? It's just a visual aid correct? I mean you can't adjust the amount of boost your using from within the cab. Can you?

I should be picking up my rig tomorrow after having the magnacharger installed. Was suppose to go today but they called and said there was a small fluid leak at one of the connectors to the intercoller, they said they'd need the truck another day. I think there having too much fun driving the thing around

I think you can order one from magnacharger... Mine happens to be a hand me down from a friend who had a supercharger on his Camaro a couple of years ago. It is a nice Autometer gauge and at a price I couldn't beat... FREE!

I can't adjust boost unless I change the pulley on the supercharger snout. Since I see that I'm making 7 PSI peak with my gauge, I know I'll move to the 2.9 inch pulley soon.

All the connections on the kit are very easy to tighten and I would say that unless they discovered it and called right before closing time they must indeed be enjoying the ride

Fubar, you are correct in that the boost can't be adjusted while you drive. The guage is just a reference device and can actually serve as a Warning device.

BTW, I run 9 lbs. but I can't remember if it is with the stock 3.4 or a 3.1. Damn, now I need to check...

[CHarris]

Ken,

It has got to be a 3.1 or smaller. I wonder if they didn't send it to you with a 3.4 the first time and changed it out when you sent the truck back for them to fix the disappointing performance.

I expect to hit 9 lbs with the 2.9 pulley.
