about 150hrs. never skipped a beat

You don't need water injection with 5# of boost. Your static comp ratio is about 8.9:1. Keep the boost at 4-5# and it should be fine on 93 octane.
I would also go with a 250 blower over the 177 if you are buying something. The 250 will make less heat and reduce the risk of detonation. Have Nickerson set up a carb for you.

Griff,
How about retarding the timing to 18 degrees total advance and running on 91 octane? Is that possible with this setup? What are the trade offs of retarding the timing to prevent detonation on lower octane fuels? Tyler will sell me a blower prepped 1050 carb, I will ask him if it is from Nickerson.

Sounds like I need to buy the blower kit.

Total agreement here. 575sci has a 256 stock, an 871 would have been a better fit with its 7.5:1 low compression. With your higher compression the 256 should be fine. As someone else also mentioned you will most likely want another cam for a supercharged application. I am sure Crocket would have a few grinds in mind. Keep in mind your hatch clearance. If it does not clear do you really wanna cut it? Are you sure you want to loose the FI?

If it were me...I think I might just trade up for more power...most of the time its cheaper.

18*?????????? is not even close to enough timing.

28-30* is probably the minimum total timing you want to run. If you only have 91 octane available, then I would try to keep boost around 4#. TC should have a good idea of what you need for the carb and it should work fine.

Here's some good reading from the Holley web site

How to get to 600HP on a budget is a major influence in the decision to supercharge. Supercharging what we have seems to be significantly less money than building a large displacement NA from scratch.

Griff,
Thanks for the technical info on superchargers, very informative.

Hey Rob,

Cant say I can help with anything about superchargers. I have very little experience with them. I can say this... Do you think you have enough room in front of your crank for that big wide blower pulley? Mine is the same boat as yours and mine wold be real tight, if not impossible.

Good point Vinny. It appears some fabrication will be necessary. I think a little saw action and some rearrangement of a crossbracket for the seat will be needed. I think it can be done without too much hassle. Although these projects all seem easier to me because I watch someone else struggle through it.
