Is This True!?

[Niko97RS]

would putting a powerdyne blower with a 9psi pulley on a 97 3.8L with 145K miles on it be safe?

this mechanic down the street from me says that a 75 shot of nitrous is safer than the blower because u "dont use the nitrous all the time, where as the blower is always on"

his claim is that the constant "stress" on the motor from the blower is harder on the internals that the nitrous because you aren't spraying 24/6

any help would be great

Re: Is This True!?

I agree with that, I mean you need to tune for the Nitrous, but something like a 75 shot IMO would be better on a higher mileage car than a powerdyne kit.

Re: Is This True!?

why though?

what does adding the blower do that would ruin my internals?

Re: Is This True!?

you are having that constant hp and torque being run through the engine with a supercharger. Going to be more strain unless you use nitrous a couple times a week.

I run a 75 shot on my car, I have 100 shot jets for the track. I only go through like 1-3 bottles a year though. I have a 97 with 104k.

Re: Is This True!?

so that mechanic is right, i should just go with a 75 shot of giggle juice and save the other $3000 from a s/c

and add life to my car

Re: Is This True!?

who runs around town all the time on 9psi?
I wouldnt
I would turn it down for better gas mileage

definetly, but turning down boost on a S/C means constantly having to swap pulleys, for road and track.

Thats what I like about having a turbo. Just a turn on the knob will adjust the boost.

Re: Is This True!?

i would disagree. i would think the sudden shock of a shot of spray would do more damage. im sure neither would be great for it, but it seems like nitrous would be the worse of the 2. just my .02

:drool: the ****ing kit arrives this week, and it will do me absoltely no good until next year.

Re: Is This True!?

dont forget that with nitrous, suddenly adds a lot of hp and torque, where as with a blower, the boost builds as rpms gp up

but...that nitrous blast lasts a few second, and is only done at WOT anyways and at a safe RPM range.

Re: Is This True!?

um,
If you are in first gear...or drop down into first while flooring it with even a 6psi SC the power will hit like a sledge hammer. boost builds very quick with a SC as the rpms get above 3000 or so. this is stress on the engine. Same as flooring it with and having nitrous kick in.

there is a difference, though. you are not 'always boosting' with a SC. true, the engine is faster all the time but that is becuase even under partial throttle the SC is pushing slightly more air (but not crossing over into positive boost) than the engine is sucking under vacuum. This makes the engine more powerful even at partial throttle. it is way cool. I realy don't think that the partial throttle phenomenom is causing extra stress.

Either way...dropping a hammer of horsepower at WOT is stressfull. I would not recommend 9psi on an older motor unless you are ready for head gaskets at a minimum.

As long as your compression ratio is good then the high mileage shouldn't matter. Get a compression check before putting on the blower.

Nitrous has more chance of ruining your engine. Because you are introducing a shot that will shock the engine. Plus, if you don't have enough fuel for it you will definately run a higher risk. With a 6lbs blower, you only need a FMU.

What ruin engines are doing very high rpm. If you don't plan on doing that with the blower all the time then you should be OK.

Beside there was a guy here with a '93 Camaro with over 200k and he put a turbo on it and ran fine.

Re: Is This True!?

The blower would be a better option depending on your driving habits. Your probably more likely to enter boost then you are spraying nitrous during daily driving, however; unless you typically go above 4k rpms constantly during daily driving its probably not going to bother your engine. Also it will be a steady build of boost, not a violent addition of nitrous.

Given that both nitrous and blower are in perfect working order I'd say the blower is safer. The arguement that downshifting and WOT with a blower would be like a sledgehammer is kind of a null point. Downshifting and spraying would be just as violent pending the amount sprayed vs boost amount. These two points cancel each other out. Given any other condition in which you would use boost or nitrous the boost comes on much less violently then the nitrous.
