I have a powerdyne supercharger (6lbs.) and i am fixing to change the pulley size and will be running about 11 lbs. Do I need bigger injectors. I have the stock ones still in.and is there any thing else i need to run this setup?

If your still at stock compression you'll need a water alky kit to run 11psi. on that powerdyne because your IATs are gonna be unreal with out an intercooler. As for your question you'll need at least 42lb injectors, fuel pump and a new low compression shortblock.

 

My 36 lb injectors were static at 6 psi on my kit. I can't believe you are still on your stockers. I would think 42 lb at least. Are you sure you are not going lean?

Oh yea, you're going to need a lot of spare serpentine belts too...

Im with him..... unless tuning is way on right and you have enough fuel..... i dont see how stockers are letting your motor still live....... A new short block is in your future if you try and run 11 psi on a stock bottom end.... i did it intercooled and it went south...... good luck

So i need to run bigger injectors 4 the 6psi setup? Where is the best place to get them? How often did you go through belts?

 

I had a great stock 98 bottom that just died on 10# (Rings)

yours may last but keep planning on a shortblock, its only a matter of time.
