Well, if you are just slapping a blower on a 454 engine, forget it. To do it right, plan on changing a bunch of internal engine parts in order for it to make enough horsepower for it to be worth your while. And forget your gas mileage....that goes out the door with a blower. It doesn't really take up much more room. Depends on what type of intake you're running currently. Basically, it may go UP a few inches, but not really alot of extra room.
To summarize, if you are gonna spend the $$ on a Supercharger, the only way to make it worth while is to rebuild the engine for the blower. Otherwise, the increase in HP is minimal compared to what it cost ya. I've seen supercharged jet boats out at the lake that can barely run 80 mph, but on the other hand, I've seen them at the races that run in the 140's. Like I said, to do it right, ya have to build the rest of the motor too, or else it isn't worth it. IMO

For a bone stock 454 I wouldn't put anything more than a Weiand 177, see quite a few of those they seem to work ok!. Personally, I would rebuild the motor with heavy duty parts and go with an 8:71!..

| Quote (Craig @ April 11 2004,8:23 am) | Hey tunamaster, I picked up 42 mph "bolting on " a supercharger   OK, so "bolt-on" wasn't the best choice of words. It took one blown up 454 and 2 different superchargers   I wrote a bit about my trials going from 72 mph to 114 pph. Here's a link.
"bolt-on" power! |
Live and learn huh!..
