It is a fact. Heat kills. Furthermore, extreme heat kills faster. Turbos produce the most heat. Everything has a "ideal/theoretical service life". Having a turbo under the hood will shorten the service life of all associated components and those in close proximity, why?, Heat. Is this true for a SC as well? Yes, but to a lesser extent. Plastic/Metal/grease/bearings/oil yada yada yada, can only last so many Heat cycles. Add this to the mechanical service life of a specified component and it will wear out faster. It is very inter-related and relevent, not a wives tale at all

 

Ahhh yes forgot about cooking turbo bearings. I guess its since most talk on the boards has been about rear mount turbos, and they don't get hot enough to carbonize. I don't think that factory turbocharged cars and trucks require any turbo specific maintainance other than running synthetic oil. Do people still use turbo timers or are those a thing of the past???

I would use the example of OEM's making TURBOdiesels instead of SUPERdiesels, but that may be totally irrelavent because of the cost to manufacture.

 

I think it's relevent if we are talking generally, yet, easier if we keep to our applications. I'm always up for a good discussion.

When I speak of heat, that can encompass alot of things really.
for instance, the very finish of a metal can influence underhood temps, i.e. alot chrome will generate higher temps as opposed to a painted finish. Furthermore, simple spray-can flat black will dissepate heat faster than any other comparable painted finish/color. This can go on and on.........

So in my case, I've just added 100-120rwhp with the Radix. And while I'm shopping for a Cam, I need to really think about the impact this will have on my setup. Hence, larger tranny cooler, High flow waterpump, ported oil pump.
These are all things I am currently condsidering because this is my daily driver and I'd like to keep it that way for many many miles.

 

I think the Magnacharger would rule all if Eaton came out with a larger compressor. Soo do I have this right? 5psi centerfugile(SP???) comes on smooth which is easier on drivetrain parts, turbos have the best powerband, and Radix is somewhere in the middle and will rip your **** outta the hole along with your 4l-60e? Whatever I have none of these! I just read alot. Can i have a ride Moregrip?

 

Ahhh............, I agree with on the Magnacharger point

yes and no on the Centrifugal, they do come on easier, however the added rpm needed for HP is what most don't like because of the associated "High RPM" parts needed to do this reliably, however, the stock LS shortblock has proven to be remarkably strong.

IMO, Turbos probably have the widest powerband, but not the best, that belongs to the Radix for street applications, again IMO.

 

I feel that reliability talk between the two is a moot point. You can easily get over 100,000 miles out of either system. Your engine and tranny will not last a long as the turbo/sc. People spend money to fix their tranny and their engine every so many thousand miles. So why not expect to spend money to repair a turbo/sc? There is nothing wrong with getting 100+ thousand miles out of an FI system before repair, especially since in the mean time you have gone through a bottom end and a few trannys.

Reliability should be part of a SC vs Turbo topic rather than a Boost Vs Boost topic. When setting the SC vs Turbo subject aside and simply look at boost.
You have 5lbs of Turbo Boost in your motor and it produces XXXXX
You have 5lbs of SC boost in your motor and it produces XXXXX
Like mentioned by most people above you will get more RWHP and RWTQ out of 5lbs of turbo boost. The question concerned the boost produced from a particular system. Not the systems cost, ease of installation, or reliability.

 

you are correct, I went off topic. I feel, as you, that reliability should always be a factor in a street application. When talking about system reliability, I don't think, or have not heard of, any 100k + LSx Turbo setups. In a broader scope, absolutely I have.
When seperating boost for boost, Turbo vs. SC, max power potential, one time, under ideal conditions for each, I agree with your above comparision.
However, if you factor in, a kits, or systems, ability to repeat these peak power #'s without an I/C I believe the I/C'ed set up will be able to replicate higher #'s, over a period of time much better than the non I/C'ed system. An example of this would be.....driving.

 

Tru, sorry for taking your thread Destructive.

 

the radix uses something in the 60+hp range to drive when you spin it fast.

in my mind a turbo kit turned down to the radix power output would be very dependable. the problem is it is soo easy to turn them up most people do and then run into dependability problems.

i have owned a whippled truck and a turbo'd truck. the boost down low is better with the blower for about .1 or .2sec. that is tenths right there. after that the turbo takes over and never looks back.

 

So, with all that being said, are there any reliable FRONT MOUNT turbo kits available for our trucks? Something you could do in your garage?

Off topic, I know, but that also comes into play when chosing the direction you want to go.
