Alert! Cheap Effective Mod For Ms3

Has anyone done this?

Somehow I doubt that anyone has done that.

I have a fool proof way of increasing torque and horsepower, all you have to do is remove the turbo and add a second bank of 4 more cylinders to the block. Next you turn the engine so that the driveline goes toward the back of the car. Next move the differential to the rear end and voila, instant torque.

I was under the impression that backpressure was part of what helped the turbo spool faster.

that's not untrue but it is difference in backpressure, not backpressure itself. the area on the engine side of the turbine is high back pressure; there are tight curves, the gas moves fast into the walls, runs into the turbo, etc... the gas will move from areas of high pressure to areas of low pressure naturally. so the lower the pressure on the outlet side of the turbo the quicker the gases will move across the blades and spin the wheel because the exhaust will escape the high pressure area quicker. it's like when you get stuck in traffic because of an accident. everyone is pissed and cranky before when it's all crowded, then as soon as you pass the accident everyone floors it and goes as fast as they can after so you want to get past the accident, just like the gas wants to get past the turbine so it can flow freely

I'm not a mechanic, but could you put something like a bov in your exhaust before your resonators or cats where if too much pressure occured it would release exhaust to atmosphere? A way to pass emissions while helping your turbo out when you need it. Probablly not legal but don't see how you could get caught (upyours)

i'm no expert but i don't think very much pressure builds up in your exhaust so measuring it would require a pretty sensitive tool. an easier way is just to either have a dump or electric cutout

page 131, Fig11.1. The best exhaust for a turbo car is theleast exhaust. RULE Back pressure in an exhaust system is evil.

Need I read on?....
But this book was written by Corky Bell so what the hell does he know.


Steve, I essentially have a BOV on my exhaust with that dump pipe, only I control when it opens or closes.

Perfectly worded. You want the greatest pressure differential of pre vs post turbo.

I Have A Turbo 4 With More Torque Than A Mustang How Do You Explain?

MU TURBO 4 HAS MORE TORQUR THAN YOUR MUSTANG HOW DO YOU EXPLAIN THAT?(hah) ...PS TOOL ARE A BUNCH OF GAY POSERS....LOL

Ah! I am just getting into that part, you ruined it for me! I <3 that book.

oh yeah, Chapter 11: Exhaust Sustems rocks, wait til you get to 12: Boost Controls You get to read about the vigilant remote wastegate vs the economical integral wastegate. Gotta love some of the lines Bell uses, especially some of the finger rules. Like:

Show me an integral wastegate on a racecar.

Haha, I can see him saying that. Although, when I was with him he was a man of few words. Then again, he had his nose dug into a pipe so I'm sure his focus was on that, not some starstruck blonde. Not too long after that did we have a actual conversation and he touched my car. Oh those were the days..

Your MS3 has 320+ Lb/Ft? Where do you get tool from anywhere in my post?

Sometimes I wonder if you MS3 folks can take sarcasm.

 

[speed3shon]

there is too much misinformation in this thread...

exhaust backpressure and exhaust gas velocity are 2 different things, and you want 0 backpressure, but the most gas velocity...

when you completely remove an exhaust, you lose backpressure (good) but you lose exhaust gas velocity (bad), thats where you lose the power...

when people say "you want a little bit of backpressure", they are wrong... but 99% of the time, you cant get rid of backpressure without sacrificing the velocity...

 

[SwampAss]

wait a minute, maybe I am new to this whole speed thing but the Mazdaspeed3 has a turbo?
