decreased life span?

[jdrumstik]

If I supercharge a 69 454, which was built for supercharging how lon is it going to last? For instance if hte enigne will only last 100,000 miles on a super would it have lasted 200,000 without the extra boost?

also, for a daily driver is te extra heat produced to much and cause frequent overheating? or does it not matter cause in overheating conditions, aka traffic, you don't pull enough RPMS for it to matter?

My best guess is that it depends on the use and how well its set up. That is more critical than the presence of the supercharger itself.
Some rules of thumb are
- most engine wear occurs at cold start up and an engine that runs too cold. One long trip is much easier on an engine than a lot of short trips.
-Engine abuse, that is, frequent overrevving will shorten its life. Of course, if yiu use it as a race car, don't expect too much life.
-Commercial use, such as using it in a tow vehicle will shorten its life somewhat.
-Dirt. A poor air filter makes a mess of things and half the Roots type blower set ups do not have any kind of filter at all.

2 worst enemies of the blower - dirt and a hickup. If the engine backfires not good - if you pull dirt in the intake you can score the walls of the blower and engine cyl. wallsv, both bad. Both avoidable. Keep your foot of the gas when starting to leesen the chance of backfire. ALLWAYS run a filter. I have a bug catcher injection set up for mine on top of a roots style 1071 BDS Stage 3 Blower. and I won't drive it without one. They aren't the best looking but can be taken off for shows, but they aren't as ugly as parts scattered on the pavement. A blower only makes boost at WOT, so in normal driving you won't be making boost, so there shouldn't be any exsesive engine wear as long as you behave. As far as overheating, a good aluminum core rad. and high volume electric water pump and you should be fine. One benifit of an electric water pump is you don't need high engine RPM's to cool the engine. You can be running max. water volume at idle if nessesary.
