So which S/C do you all think is best for a daily driver that goes to the drag track occasionally? Which one has the most power without doing damage to the engine? I've thought about the Saleen but am unsure this is the best way to go.

 

There will be a bunch of different opinions on this...... I have a Vortech and IMO it is a great blower for someone who wants normal day-to-day driveability but also wants something that occasionally screams at the track.

I also feel that a centri-style blower is safer on a stock engine in the longrun, since you don't build peak boost until higher rpm. I would think that boost = stress and if you get peak boost at a lower rpm like you do from a twinscrew, you'll be into the boost more often, creating more stress on the engine than a centri since it's peak boost isn't until much higher in the rpm range.

Just my 2 cents.

 

Tom twinscrews are positive displacement blowers. If you don't get into it, there will be no boost.

 

one word........WHIPPLE!

 

Thats why Saleen's (Screw type) S/C appeals to me, Boost in the lower RPM range! I think Saleen has the cleanest looking S/C on the market!

 

Honestly from all the opinions I've gathered from engine builders, to techs, to guys on this and other boards.... if you're worried about stressing your stock engine don't put a blower on it.

Any blower ANY will stress your engine. Your engine was designed from the factory to put out 300hp at the crank... anything above that is going to stress your engine more than if you didn't put a blower on it--period.

I understand your question... you want to do what's best for the motor but you also want to have fun. I'm the same way... the problem is that you can't have it both ways.

What's best for the motor is to leave it stock.

If you are going to put a blower on then do some research and see how many people have popped their engine on the particular blower you are looking at... and why they popped.

My personal opinion... and the way I'm going to go... is with Saleen. There are many many reasons that I've decided to go with Saleen and I'm not going to list them here... there are plenty of threads about these things.. but in the end I understand that anything can happen, with ANY blower.

Like Chris said if you don't romp on it you're not going to be into boost and the way you drive the car will have a direct effect on how your engine will handle the new boost. In other words if you don't drive like a crazy man every time you get in the car your stock internals will probably last longer.

But that's about as conclusive an answer as you will get... "probably" "maybe" "should be fine."

The simple fact is these cars haven't been out long enough for us to know what the longevity of the stock internals with "x" blower at "x" pounds of boost will last.

Don't want to rain on your parade or anything just want to give you as honest an answer as I believe I ever got.

Good luck with your decision.

 

there are thousands of daily driven SC mustangs. Keep stock setting..around 8psi and a nice safe tune and you will not have any problems what so ever.

normal driving doesn't use all 300hp...so just because you have 450 on tap with SC it would be negligble.

 

That's kinda misleading..... if you don't get into it, a centri won't make much boost at all either.

Besides, who runs a blower and doesn't get into the throttle LOL!

 

I've always heard that a Roots-type blower will be the most reliable for everyday applications. Have you ever seen a factory centrifugal blower? How about twin-screw? Might be a good reason for that...

 

took the words out of my mouth....

 

Well with the Saleen bypass valve, at general cruise you are making negligible boost so there's that to consider..... less heat buildup and stress.

And even with your foot IN it, as shown by my dyno/tuning graph from last week, I was making peak boost at the top of my pull rpm wise

If I had my foot in it hard and shifted at 3 grand going by my results, I was still only registering 5/6 lbs of boost at that point.


I will say this - once you get a taste of Forced Induction....... it's addictive!!!!

 

The koenigsegg CCR uses a centrifugal supercharger from the factory... on a Ford 4v modular no less.

 

my sig says it all. the JDM/SALEEN combo meal can't be beat. 500+ kits sold/installed. There have been "0" motor or trans failures since they came out 2 years ago.

 

Yeah - COST I believe if I remember my research.

The CLOSE tolerances required with twin screws makes a roots more economical for a mass production vehicle due to it being cheaper to produce.

 

No offense, but that's not the supercharger promoting "0" failures, that's the tune. JDM knows what they're doing for sure, but if the tune is right any blower will be relatively safe (assuming common sense is used ).

 

Common sense....... that's that stuff that prevents you from lighting the tires off every red light - right??

 

Yes, that's it...... that's why I only do every-other red light!

 

YOU... you are good, you.....

That's what I like - thinking outside the box.....

Thinking like that already, you better get BACKUP tires for the rear for those new wheels, Hoss!

 

Maybe someone will be nice enough to correct me, but I have yet to see any Saleen S/C engine failure

 

So the Saleen pumps "special" air? It's the tune.
