Any parts from TCD involved in this?

[daniel635biturbo]

@smhorse No Almost all parts is Custom made by me, except Turbochargers and Intercooler. (Bypass Valve (Pop off) is Mitsubishi EVO)

[filipHRboy]

What size are the rims ?

[daniel635biturbo]

@filipHRboy 8,5x17" OZ-Racing x-spoke, VERY rare 3-piece split wheels.

But now i have OZ-Racing Futura 8,5+10x17"

[BiteDoctor]

[MrRadjevic]

Hello, awesome car. Is bit turbo better solution than single turbo, what do you think? This video is my favorite :) keep posting

[TheSaltySea]

Very nice car, props on the build.

Wow! she's a beaut... How long did it take you to fab up all of the piping for the exhaust mani, intercooler etc?

[daniel635biturbo]

@yayo828384 About five months of work.

But VEMS (ecu) Installation were done the winter after.

I´ve been running with the Bi-turbo engine for three years now.

[daniel635biturbo]

Well i am happy to say that the car driver and builder is the same person (me).

That tells me i am half bad, and thats good enough :)

Maybe even half badass.....

[Yipsyking]

Bad song, bad driver, but the car i just great ;)

[CowboyPenner]

Awesome car!

[dilawer321]

lol song is badass

[DADDYROBEE1]

who did your turbo kit?

[daniel635biturbo]

@DADDYROBEE1

The "turbokit" is completly homemade, exhaust manifolds, intercooler, air pipes.

With Alpina B10 Bi-Turbo as source for inspiration.

yea im not quite sure why people go with two turbos for this while wih one it seems like you can get same performance?

[daniel635biturbo]

@0drunkerd0

With two smaller turbos, you generally get much more low Rpm. touque, this setup gives 0,4 Bar of boost @ 1600 Rpm. and above 0,8 bar @ 2500 Rpm.

The flexlibility of this engine hard to beat with a singelturbo setup.

And also the responce of the engine generally gets better, with smaller turbines.

But a singel turbo would be better if you only were looking for highest performance.

Have in mind that the car is very heavy and only revs about 1700 Rpm. on the highway.

@daniel635biturbo

Any chance there is or will be a write up of this build somewhere online? What are the HP and Torque numbers from this build? Would the same setup work on any M30 engine, like in the 535i or 735i? Thanks. Definitely an inspiration!!! I hope to follow in your tread marks ;-) Where are you located btw?

[smhorse]

@mrkanda : You're not the only one who'd like to have a go at this!

[bigfacejimmy]

nice - can you take a video of the interior - I notice you have the m3 seats

Great job man! I'm doing a single turbo on my 85csi I'm hoping to manage 400whp with a 3.5" exhaust :) :) I can't believe how quite your car is!

[AHONKANEN]

What kind of power gains you got with shose modifications?

[daniel635biturbo]

The Boost pressure is 0,8Bar you can add about 80% power gain to the engine.

200*1,8=360 Hp

Then add a small powerloss in the turbos, since exhaust pressure is higher.

So lets say 350 Hp. and around 500Nm

Hopefully i will run my car in Dyno during 2010.

[bbjanee34]

Beautiful :) very nice!!

[stonerumble]

farligt när lyckstolpen i början där..

[daniel635biturbo]

Är förhoppningsvis inte så nära som det ser ut :)
