This will be the view of some mechanics. However many owners on these boards will attest to the reliability and drivability of aftermarket supercharger systems, I would not let 1 nay sayer be your deciding factor. We provide safe linear levels of boost with the use of the Vortech unit. This will not damage an engine like a turbo could due to spikes in power far from redline.

Thanks and Happy Holidays!

There are a quite a few cars on the forums that have FI(forced induction) some with MANY MANY miles on them.
IF tuned right they are reliable and fun to drive!

I agree with "I would not let 1 nay sayer be your deciding factor".

But I am not sure about this statement..."This will not damage an engine like a turbo could due to spikes in power far from redline."

IF the tuning is done properly what would it matter where the boost is?

As you know I went to a smaller pulley(a lot smaller),on my VF supercharger,than your kit provided,thus making quite a big low end boost increase(far from red-line) and I held together just fine with some simple tuning tweaks!
I do not claim to know all about this but IMO it is all in keeping the PEAK boost levels at a safe level BUT with the proper tuning ...
More boost low down will ultimately make your car faster...?!
I guess we will see the end result after TPC markets their turbo.
One thing to note is....
FI cars are a blast to drive !
I had the VF kit on my 997...but luckily enough now I am going to try the TPC turbo.So I guess I will get to compare the two systems with an unbiased opinion!

Hi Stacy,
If you look at your dynos with the SC installed, you will see that the power band is similar to stock in the linear production of power.




If you now look at a typcial turbo plot and how they produce peak power/torque before redline, you will see what I am reffering to.
If you produce you peak torque at 4Krpm VS 8Krpm, you are effectively doubling the stress on engine internals.

Hey Sean,
I see what you are saying about the linear power....trust me I found that with the VF charger BUT isn't any type of boost gonna cause some sort of stress on a motor....I just don't understand why the stress at lower level rpm's is any different than the stress at higher rpm's!?
Boost is Boost!

I do understand that you will need proper tuning to accompany the quicker boost level...I would NEVER run your (VF) charger on a stock tune,I would never run the VF tune on the TPC turbo....so IF TPC does their tuning to allow for this quicker boost level......why would there be any more stress on the motor?
If any thing the turbo should make more power from the same boost.....no need to turn a compressor!
IMO quicker/faster power delivery(lower RPM's) will be quicker and easier on the motor...NO?!
Again isn't it all in the tuning?

Did your mechanic tell you how far down the road, or which road you had to drive on before you started seeing problems? I have already driven the equivalent of twice around the earth with my supercharged, otherwise stock 996. Maybe I missed the road he was talking about.

As you go through life, you'll find that those who claim something cannot be done are the same people who know little about the subject matter. The more sure they are of their opinion, the less they know.

 

I don't think they are going to be a good choice for an install.
It seems that they are a new shop as they are in their first year of business. They may not be familiar with anything aftermarket yet.

You may want to contact Ron @ IPB AutoSport in Sacramento for a quote on the install. He is already an authorized GIAC dealer and a Porsche head! 916-453-1465

Below is a properly tuned 91 octane(california) tpc turbo tune on a 3.4L cayman. Keep in mind that this system(installed on a cayman running 98ron) just won EVO magazine's tuner car of the year. we have tuned 93 octane caymans running 6psi at 450whp.

 

here is another running lower boost but on 93 octane... this is our generic "flash" pre routine switching and boost control... But you can still see lots of drivable torque and nice peak horsepower... remember it is all in the tune.

Sorry to hijack the thread.

 

It's all in the tune!

 

Sean, i dont think a supercharger dyno from 4 years ago is really valid at this point... judging from the fact that we completely changed types of induction and fueling.

 

I understand. But just to make the point, this was a good dyno.
We have yet to change our system to a new style in the last 5 years.

Have a Happy Holiday!

you too man

 

Shaj what is your driving style like? Is it for track or for around town may help you determine your course. I think both systems are good and compress air and when properly tuned the costs are about the same and hardware and software are constantly evolving so, if you have a chance is to try both.... the gearing of your car and driving habits can help. GL

 

Hi Mother (mom?), if I can be honest, my style is more jack rabbit starts off the line and and also accelleration when I need to do a lane change around a slow car or something on that order. I'm less interested in peak speeds, it's quick bursts of accelleration that I thrive on. I don't do any track driving. Does that help?

 

Judging by the quick boost of TPC turbo and your driving style I would say the turbo is for you!
