Life or supercharger

[JimJim216]

Need a seriouse answer from someone who knows.
PES says that a supercharger doesnt effect your engine life in anyway, but my local Audi dealership, as well as my common sense is saying, supercharger=hotter engine=less life.Want to drive daily and be able to race ocationally, would like to keep car for at leased 7 years, 40k millage right now 98.

If u want to dive it every day the i wouldent get a super charger. The only way that you could safly make you car non aspriated would be turbos. With superchargers it takes power to make power so the engine is always working to turn it. Not only that the reason why the didn just put on the biturbos on a 2.8 is the cylinder walls on it are to thin to make alot of boost so they made the 2.7 with bigger walls to be able to make moe boost. So even with the super charger idk if you can get alot of boost with out risking alot of poblems. Super Charger should really be for bigger engines liek the 8 cylinder s4

maybe its just me, but i didnt get that. how is adding turbos to a car a way to make it "non-aspriated"?

[Talibangunner925]

i meant the only real safe way to to make you engine non asprated to get extra power would only really be to get turbos

The SC will add wear but not a lot I would be lying if I thought it did not. But to say a SC should only be put on a V8 and up would be crap as the SC pushes less psi than a turbo so putting less work than a turbo car. No these engine where not built for SC but then one could say Turbo cars were not built to be tuned but yet most of us do. The main thing about tuning products is the company that make them and the testing they do with their kits. PES did lots of testing when they made these kits and tested them till they broke the engine and that was running 10.5 psi and the kit is made to run 8-8.5 psi. PES has a 3.0 sc kit due to be realised but they will not release it till all the testing is done. I know of guys been running these kits in there 100k + mile cars for over 2year with no problems at all. Anything that is adds power to your car will add wear its just a matter of knowing when you have added too much power.

i was sayign it should only be put on the v8's becuse with the v6 you aill actually fell the lag when the supercharger is taking power from it and that is not good fo the car it putting to much of a strain. Mby on the 3.0 it has engough power to not have any lag but i was sayign the v8 could defnatyly hande it better and would be alot safer than the 2.8

In some ways you’re right in another way your wrong. If the V8 is made close to its limit then bolting on a SC would not help yes it would probably have more bottom end power but that would not mean it was better suited. I feel no lag on my SC as it pulls from the moment you put your foot down where as a Turbo are no power then loads then none (depending on the turbo set-up) but a SC like mine say will have a constant power all the way to redline and only the REV limiter stops it pulling. I have a friend with a total custom build VW Lupo with a 1.4cc engine and a SC mounted on it he suffers no lag at all and runs 154hp. Now for a car that lighter than a Mini Cooper S he eats them for dinner and like mine he pulls all the way to redline with no drop in power at all. This is the thing about SC there is no real Lag unlike Turbo cars.

im sorry talibangunner but i think you may be a little confused on some things here. one is aspirated, i have to go back to this. i hope that you never make any car "non-aspriated", what youre saying is that the car doesnt breath or take in air. cars cant operate like that, they need oxygen for combustion. your car has to be aspriated is some way. i think what you wanted to say is naturally aspriated, but still you must be confused. the reason is that a car can only be one of two things in this regard, naturally aspirated (n/a) or boosted (also called forced induction). boosted/forced induction refers to the aid of a turbo or supercharger or nitrous oxide system to force more air (and therefore oxygen) into the cyclinders making the engine more powerfullly (the more oxygen the great the combustion). therefore adding a turbo would make it boosted and not n/a.

another is your quote "it takes power to make power" in reference to how a s/c works. youre right, but think about how a turbo works. it takes a flow of something over the turbine to get the turbo to spool. that thing of course is the exhuast gases from the engine, and it take a revving engine to produce that gas. therefore is takes power to make power with a turbo as well as a supercharger. a turbo isnt some magical thing that creates power out of nothing.

the last of course was how your described lag for a supercharger, turbos are the things that have lag. it takes time to get the turbos spinning at first because not enough exhaust is leaving the engine. when enough exhaust flows over the turbine power is finally produced, the time in between is the lag time.

so there you go, i hope this clears up some confusion, for everyone.

it take power form the engine so it take powere for the engine the turbo take fom the exaust the exaust flow doent give power to any thign so really it doesnt take power with turbos eather also i guess what i mena to say was "non naturally asprated"

[MikeLee2484]

it still takes work from the engine to produce the exhaust gas. the exhaust doesnt come out of nowhere, true it is expelled gas leaving the car but it is still produced from the engine. the statement "it takes power to make power" is just as true for turbos as it is for superchargers. most superchargers take less than 1 hp to get its screw turning as it is, so it really isnt taking that much power anyway. and thats a nice new phrase, "non-naturally-aspriated". but i think ill stick with boosted.

lol... em eye the onli 1, or iz every1 used to et end payign noe mind?

[MikeLee2484]

yeah i agree with you (though i had a hard time reading what you wrote at first)...i think the bs/back peddeling was in full force the day that was posted

all i have to say is AQUAcooled
