hello everyone, been a long time since I posted but I wanted some educated opinions. I have a 72 chevy truck with a zz4 in it. Engine has less than 20k. Was looking for more power and was thinking about heads, cam etc, but I noticed that vortech has and "entry level" blow-through supercharger kit for around $2k. I know by the time it was installed and running i'd have 3k in it. Then I wouldn't have to crack open my relatively fresh crate engine. Seems like reasonable 150hp without sacrificing low end power. Anyone have any experience with these. Are they dependable? Hard to tune? Just wanting some input. Thanks guys!

Guess nobody has any experiences with them. When/if I install one I'll be sure to share my experiences.

i didnt respond because i have no experience with them.     your probably right about it costing another $1,000 before your done?     i would imagine you'd need a blow-through carb with a boost referenced power valve at least?

I have a lot of experience with nitrous but I have never ran a supercharger of any kind. I think you are right about the extra 1000 before you are up and running and you need to know your internals are up to the extra boost. An intercooler is also a good idea on a blown engine.

I think water/methanol injection is the latest way to cool the intake charge and keep detonation at bay.

Looks like I'll need a boost referenced fuel regulator, blow off, better fuel pump, and possibly boost referenced ignition. Wideband a/f ratio gauge also. Then I'll have to figure out the carb tuning. Then 10 other things I've yet to discover. Getting expensive. Starting to sound like more of an over the winter project than an over the weekend one. I think my shortblock is up to it, but my transmission(700r4)is another story. Still wanna do it!

Don't give up on your dream. You are doing the right thing in asking questions and then making an informed decision. You will find the weak links as you go down the path of more power. I know I did. The transmission will be just one of them.

Having done a similar install,  I can give you some info. I put a v-2 vortec on my gmzz383 crate motor. set it up for 5 lbs boost. It gave me approx. 100 hp[ to the rear wheels. Cost a lot of money, blow thru carb, new ign box with timing retard fuel pump. I had a th-350 behind it that was not giving me any problems but it only lasted 2 weeks with the blower. Replaced with th-400 built for 1000 hp. Two months later I blow a piston. The gm crate motors have cast pistons good for about 500 hp I replaced the lower end with all forged parts. I wished I would have done this in the beginning instead of buying the g-m crate motor. It wou7ld have saved me a bundle.  This was not a track car and was only nailed in second gear `till 5500 r`s If I mistreated it I could understand. Anyway from me to you, don`t do it.  It did haul ass though. Also an intercooler would be nice to have. There is a big diff in power with cooler air.                Hope this helps, Shriker

This is good advice. As you can see the motor must be built to handle the extra boost and even then getting the power to the ground can be tricky. As stated an intercooler is a big help.
