Thanks for reading this. First off im new to the supercharger field! Im installing an older Kenne Bell 1.5L blower on my recently purchased 1986 gt mustang convertible. As far as i know the only mods are what i think to be an E-303 cam and a cold air intake. I know to run the blower i need to go mass air, which has already been done. My question is there anything else as far as upgrades that i need to do? Oh yeah i bought some underdive pulleys That kenne bell reccomended i need for running the small boost number that i am. If anyone has any advice or comments feel free to email me or repost something. Thanks!

Well I thought that, but the instructions dont say anything about changing them. also i have a buddy that builds some of the baddest 3000 hp drag cars i have ever seen and he didnt say anything about them either. But when i bought the blower it had FRPP 24 lb injectors with it...So I'm a lil confused about that....Thanks though, anything else you might suggest?

If it has 24 pound injectors already, those will suffice if you keep the boost mild, 6-7 psi. Then you should upgrade the fuel pump to a 255 lph unit, you don't want any chance at fuel starvation.

But in the online manual it dont say anything about the injectors being changed, i know it wont hurt, but do you think its gotta be done. and how bad will this blower hurt my gas mileage. it gets around 14 or 15.

The manual is just a guideline, it's up to you to get it tuned properly. You add that blower to it, you'll be going past the limit of the stock 19 pound injectors, and this isn't something you want to find the limit of. In this case, you best be on the safe side and it's better to have too much fuel and turn it down rather than not enough fuel and blow the gaskets out. I would install the 24's that came with it and go from there.
Your gas mileage will go down slightly, not excessively, due to the higher flow of the 24's. It won't kill too much of it.
