Turbo Qs

I'm going to tell you what others have told you: it doesn't work like that.

you can take the same turbo and put it on two different cars and get two differrent sets of numbers.

Factors it depends on:

Overall flow
Fuel grade
Altitude
Tune
Valve size
Intake path size/smoothness
Condition of compression rings
Total ignition system
and the list goes on and on.

I can take a t3/t4 at .57 trim, .63 AR and make 200hp on one engine, and 300 on another.

A well maintained high-mileage engine may withstand 300hp, while a hard-beaten low mileage engine might blow at 250.

I think you get the point.

What BlackJack says^^ is very true, and to add to it, 10psi on one turbo does not flow the same as 10psi on another turbo.

Let's say for example you have a GT1548 compared to a GT3582R on one given engine both pushing 15psi. The GT1548 will be close to it's maximum output and will probably produce somewhere around 170-190hp. The GT35, because it flows so much more air, would probably push over 400hp at the same 15psi of boost.

Which mods are those? My car is stock

^^Really? Hmm...my brakes never came with a Corvette logo on them...

[alerored04]

Yup, straight from the factory that way.

If you're worried about popping an engine, isn't the GM supercharger the best alternative?

not on the 3400

and any power adder is capable of adding too much power for the stock system to handle. people have blown engines stock.

correct...due to the fact I have a spare pcm...If I ever sell the charger kit that I am running, I will sell the pcm with it that was tuned for the car. This should get the end user close enough to have some fun without going boom. Granted each car/engine/pcm combo is slightly different.

If Magnacharger put the time into the 3400 kit like they did the 3800 kit, this would be a viable option....and if there were more then 12 or so out in the wild.

i believe the official number is 17 or 18.......

If you're worried about popping an engine, doing a lot of research and learning a lot about boost is what you should do before you add boost. A turbo or supercharger will both pop a stock or built engine if it's not tuned properly.
