turbo and car pics

i think its a t3 -61 i think (maybe a t3/t4 -62 i cant remeber) has an instant spool with like no turbo lag. Dont be jealous and bash because thier set up is much nicer then yours and then try to make a reason thats not true.

Instant spool with no turbo lag? You mean what I like about the MSP turbo? I am glad we are on the same page. http://www.mazdausa.com/MusaWeb/displayPage.action?pageParameter=perEngineCallaway#garrett


All I said was that I didn't really like the idea of starting with a 1.6L... And here we go again.

That's not true at all. The MSP turbo is actually really great for a daily driver situation, I was talking more about a different turbo pipeing setup. I'll take my small, quick to compress turbo over some oversized inefficent setup anyday.

do you know much about turbo's, sounds like not much. oversized inefficient? it takes 15psi(where its efficiency is gone) out of your t-25 to = like 9 psi from a t3/t4, again sounds like you don't know what you mean.....i personally would have a larger turbo(laggier) for daily driving because you obviously would be creating less boost driving around = better gas mileage..

Wait, PSI is different depending on what turbo it comes out of? 25psi = 9psi depending on turbo?? This is a strange new development I have never heard of. Please explain how this works. Is this like painting your brake drums yellow to stop faster?

And a large (laggier) turbo is the most annoying part about a daily driven turbo car. That is exactly what I DON'T want. I want boost now, when I need it in traffic, not when I am at 6k RPMs flooring it.


Oh, and if gas milage was really a concern, I doubt either of us would be going F/I, now would we?
 
what th hell? what do think people buy bigger turbo for the fun of it? simply it means a small turbo at 15psi would equal what a larger turbo would but out at 8psi

15psi = 8psi? (braindead

Maybe I AM missing something? I always thought a larger application was for more boost at top end for more horse power total. The large turbine takes longer to get going, but in the long run produces more boost. More boost means more compression, and that means more horse power. The downside is the gains in turbo lag which makes for a very annoying daily driver setup. People buy bigger turbos for 2 reasons: Looks and top-end power... Unless you know somethign I don't. (Hey, anything's possible.)
 
ALSO: (Just thought of this) Are you talking about which turbo makes boost more efficiently? That's a whole different can of worms right there.
 
Eample: Imagine a 1inch water hose and a 3inch water hose. Booth uses the same water pump and are pumping out at 10psi. Which hose will produce more water(hp) at 10psi?

That is why I want new piping not a new turbo. I want to change the size of the water hose so more water(hp) gets through. What we are talking about here is the same size hose with two different water pumps.

Now with filling in the blanks...

Imagine a "1inch" water hose(t25) and a "3inch" water hose(t3/t4). Booth uses the same water pump and are pumping out at 10psi. Which hose will produce more water(horsepower) at 10psi?

The "3inch" water hose (t3/t4) will produce more water, or horsepower in this case, at 10psi.
 
Though you are on the right path with larger piping and larger exhaust. That will also yeild more power also. But getting a newer turbo isn't just for running higher boost.

If your not looking for huge horsepower and only looking to get around 230whp, then I don't see the need to upgrade to a larger turbo. You can achieve that with larger piping, bigger intercooler, larger exhaust, and of course increasing the boost.

Like I said, I like the stock MSP turbo.

I still think your analogy is off. It's true you are going to get more flow from a bigger turbo, but I don't see how the ends are going to be different if they both produce 10psi (assuming they share the same ammount of effency at 10psi).

Why do you think some Mp3's are getting much higher hp numbers at 7 psi than an MSP? Because they use a bigger turbo!

If you have a T3/T4 at 7psi it is going to push more VOLUME of air out since it is bigger when compared to a T25. It's not just psi, it's total volume. This was confusing to me when I first started learning about turbos too, but trust me and everyone else telling you, a bigger turbo will push the same amount of air from a smaller turbo at a lower psi.

I, however, do agree with you on one thing, I am going to stick with my T25 for a while because I love the instant boost.
