Supercharger for 2.5

[RandallNeighbour]

I say bigger brakes are needed and I'll put them in after I do my SC add on... why?

Right now, I can make it from a stoplight near my house to the freeway light, reaching about 60 mph. With the supercharger, I might make it 5-10 mph faster, which means I'll need more braking power to handle the increase in speed over the same distance.

Now I don't do much street racing from light to light (actually, I don't do any at all), but I figure that braking ability should rise with horsepower to keep things safe. There's only one thing more important than going fast... being able to stop faster to speed up again in the future.

Hi,

As already stated, the biggest gain from using bigger brakes is gong to be their Fade Resistance, and this only shows up in Rapid Repeated Use, such as on a Track. If you're not Braking every 5-10sec., adequate time has passed for the Brakes to cool, about 20-30sec. is sufficient time to avoid Fade.

If the current Brakes are adequate, they're just that - sufficient to do the job. Just because you get to 60MPH Faster doesn't mean it has suddenly, myteriously, become more difficult to Brake to a Stop from 60MPH.

If you simply want to add them as Automotive Jewelry, that's perfectly FINE. But, simply adding a Supercharger is no justification for upgrading the Brakes.

If you just want them, then go ahead. But not for the sake of some convoluted logic which says that because you are making more power, your current Brakes are somehow automatically inadequate - you're OFF the power when you apply your Brakes anyway. If your Driving Style or Conditions haven't changed, the OEM Brakes are not at all inadequate...

Happy Motoring!... Jim'99

Jim, you just saved me $3800.00. Thanks!

Ditto on Jim.

Unless you are tracking, I would forget it!

PorscheDoc:

1) do you use an intercooler in your setup? Is there any danger of detonation?

2) This may be a topic for a different thread, but how about a comment on why you didn't use turbocharging as your method of forced induction.

What kind of life expectancy is there on these SC's before they need to be rebuilt? For example, the G-lader in the VW Corrado tends to start spitting Apex strips after about 80k miles, necessitating a rebuild.

How many miles could one reasonably expect to get out of these before needing a rebuild or replacement? What kind of service do these SC's require to keep them going?

Thanks

I will check on the life expectancy with Stephen, I don't know the answer to that off the top of my head.

The only maintenance the units require are an oil change (on the unit itself since it is self contained) every 6k miles or so with procharger's oil.

1. We do not use an intercooler on this setup, there just is no room. The programing is done by GIAC, and the air fuel mixture is excellent, thus no detonation.

2. Quite honestly, there is a lot more involved in adding a turbo versus adding a supercharger to do it right.
