Suspension / Free Strut Brace

« on: April 17, 2010, 04:29:03 PM »

Let`s take a look at what I did today... ( I know that it`s crap but don`t forget that it`s free

)

Everything started from this

Some imagination

Cleaning from rust

There is awlays first time

... and maybe last

Protecting my frankenstein strut brace from rust

Let`s see does it even fit :confused:

And finally

Sometimes standalone isn`t better solution. Having done nothing serious to your engine editing the chip ( EPROM ) is better than MS

EPROM Programmer in Bulgaria coasts about 35 eur, tunerPro is free, EPROM chip is about 1 eur or less. The only thing you need to know is how to tune your chip, so this is my problem. I don`t know how to tune DME

You need Willem programmer for eprom

Does someone know how to tune stock ECU? Or at least how to tune the ignition map?

Swaps, Turbos, Buildups / Intake manifold for NA

« on: November 21, 2009, 08:45:18 PM »

Ok, I already know the design of the manifold and also the runners lenght but I couldn`t find info about the throttle... I have 65 mm throttle from M30B35, but this week I founded that the M52B20 throttle is about 67 mm wich is not big difference but if I need to replace da trottle it would be more easy to find M52 throttle than M30. I`m worried about something else - bigger diameter of pipe - lower air speed, smaller diameter of pipe - faster air speed but less air! As I mentioned I couldn`t find formula about how big trottle I need... I want better response! How to calculate how big throttle do I need or the bigger is the better

I calculate it like this - 4 cylinders engine and 4 intake valves with diameter 45mm, as you know the engine uses only 90% of the valve so 41mm diameter... This means that r=2.05mm! S=Pi (3,14) x r x r
3.14 x 2.05 x 2.05 = 13.2 ... this is the area of one valve but I have 4 valves so 13.2 x 4 = 52... In other words this is the area from wich the air comes into the cylinders. So I need throttle with area about 52 or little less to have better response and also getting enough air.
We have throttle with 65mm diameter and r=3.25 so 3.25 x 3.25 x 3.14 = 33... smaller than the area of the four valves! That makes me think that something is not as I think.

Any ideas
