Who created this E24 Bi-Turbo?

Anyone we know?

Impressive. I'd like to see more stats on this one.

Its a swedish guy named Daniel!
He made an awsome job with that car, and theres a lot of "special" solutions on it.
You want some more?
Watch some pics and data here: (in Swedish, but u will understand! =)

In the name of all that's holy, have ye ever seen acceleration as fierce as this?!?

Okay I confess you have found me now.

As Patrik (m635forever) told you i live in Sweden, and you have seen a couple of photos.

I bought my 635 1 April 2003 and it looked just like this.

In really bad shape.

The car were abused by 18 previous owners and had 250000 km or 156?000 miles.

It cost me about 4000 Us dollars (26?500 Kronor)

In autumn 2005 restoration were finished and i drove it for a couple of years, back then it looked like this.

During winter 2007-2008 i built a new engine wich is based on a e34 535 engine.

OOOHh yes thers a lot of work done.....

And not only on the Bi-Turbo engine, also fibreglass Front and Rear bumper, including rear spoiler.

Pictures from 2008 and now i also have OZ-Racing X-spoke 17x8,5" split rims. (Extremly rare)

Other small mods.

In winter 2008-2009 i installed a VEMS engine ECU
(Earlier i used Motronic standard ECU and e34 m5 fuel injectors)

Fuel catch tank.

Larger fuel pump.

Winter 2009-2010

Change of rims to OZ-Racing Futura 8,5+10x17" (Wide rear rims)

Of course in bad shape when i bought them.

Here TIG welded outer rim, badly scratched.

And cracked.

Getting there...

Nice :)

In 2010 i ran the my 635 in a Dynapack Dyno.

With slightly higher heart rate than normal looking at my Laptop.

And this were the result.

360hp@wheel hubs (approximately 390hp@Flywheel = 286kW)
And 595 Nm

This were achieved with 1.0 bar boost pressure or 14,5 psi as you know it.

This is the SHORT story about me and my BMW 635 from 1983.

Any bad grammar, spelling or choice of words is my own, but i think its better then using Google translator...

Maybe i continue the story up to 2012 later on, my brain is starting to overheat writing all this in english.

daniel-635,
Thank you for sharing this incredible story. Such excellent workmanship and attention to detail

I hope you will share more when you have the time. We would all be appreciative

I like your work on this masterpiece, especially exhaust and intake manifold setup.

Well done

Hmm....an E24 Bi-Turbo pack. Wonder if the fellas at Fritz's Bits should take a look at this one.....

Brucey · Post by **Brucey** » Tue Feb 14, 2012 12:25 am

good work fella!

nice one!

I especially like the fibreglass front spoiler; do you still have the mould or the buck that you used?

Now, if your winters were not so bloody awful your cars wouldn't be as nice, now would they?

cheers

Great thread, i'm hugely impressed.

@ Brucey

I actually dont have a mould for front bumper, this is the only one so far.

There are for sure pros and cons with our winters !
As you say November - Mars is "Garage season" :)
Actually the crayziest cars in Sweden tend to be far up north eaven above the Polar Circle.

Or rather stell meets Corrosion

Thank?s all of you for the nice comments.
Next time there will be more pics

They are actually doing a twin turbo V8. It kicks out 720bhp!!

And fuel consumption? l/100km?

daniel-635 · Post by **daniel-635** » Sat Feb 18, 2012 5:36 pm

Well about the fuel consumption, let's say it's variable.

When cruising 90 km/h 9,5l/100km almost down to 9l
Usually daily driving results in 11-13 l/100km.
But up to 16 has been measured

Teoretichly i can empty a full 70 litres fuel tank in 35 minutes

How to break with all this power ?

Rear brakes is stock BMW e34 300x10 (bolt on) brakes.

Front brakes is however more complicated.

Drilled discs from BMW e46 330i which are 325x25mm
Combined with slightly modified BMW e39 Aluminium calipers.

Mounted in a CNC milled custom bracket. (Together with test parts)

Sadly I had to reduce the thickness of the brake pads due to a too tigth fit towards my OZ-Racing rim, or actually the screws.

But, it has been proven to work very well !

To be able to handle the car you also have to sit tight behind the steering wheel, e36m3 black leather seats is a nice upgrade

Especially from this

Whaaat do they fit "bolt on" ? No they do NOT

Next update problably will be about the chassis

M635forever · Post by **M635forever** » Sat Feb 18, 2012 9:10 pm

What can I say!???
I just cant get enough of this car, as I said before Daniel, im deeply impressed of what you accomplished.
And Im really jellous of your E36M3 front seats!!

ThomasFB · Post by **ThomasFB** » Sun Feb 19, 2012 12:18 pm

Gorgeous car and excellent work, Daniel.

I guess you are familiar with this engine builder:
vsmotor.no

As much as I hate the nordic winter, something good may come out of it:
Not e24, but have a peek at these, this is serious stuff:

http://www.vsmotor.no/en_videos.html

Some more stuff with the E34 may be found on Youtube.
Cheers,

Thomas

daniel-635 · Post by **daniel-635** » Mon Feb 27, 2012 7:35 pm

Yes VS Motor have some cracy cars, i have seen a few of them live

Well as you probably already understand also several parts on chassis is modified and or replaced.

Reinforcement under rear seat.

Front subframe connectors.

Reinforcement of chassis i passenger footwell.

Rear Subframe connector.

E34 Aluminium Wheel support arm, together with Rollcenter adjustment plate.

m535 3,07-1 Finaldrive with 25% Limitedslip diffrential
Together with Polyurethan filled silent blocks.

Stainless steel exhaust and Bilstein front shock absorbers.

Adjustable Yellow Koni for rear axle.

Have i forgotten something ? probably yes..

A small glance of my garage today, Clutch change (due to noise, not slip)
And other small upgrades, you know it's winter time so what to do if not spend time with your car :)

GripGreg · Post by **GripGreg** » Tue Feb 28, 2012 3:30 am

Great job!
I like what I see at the differential.
What did you do with the steering wheel? I'm interested.
Can you post pixes?
Greg

ThomasFB · Post by **ThomasFB** » Tue Feb 28, 2012 7:34 am

Does it really need that much rollcenter correction?
Looks like a 30-35 mm spacer.

daniel-635 · Post by **daniel-635** » Tue Feb 28, 2012 11:29 am

ThomasFB

Thery are 27mm thick

And here you can see the theory behind them.

White = standard height
Blue = 40mm lowerd without RC corr.
Red = 40mm lowerd with RC corr.

I'm no chassis expert, but the car feels better especially i fast corners.

What do you think ?

ThomasFB · Post by **ThomasFB** » Tue Feb 28, 2012 1:05 pm

Daniel, I'm no expert either, but been around "elsewhere" for some time.
A 40 mm lowered BMW usually needs some correction, as the lower control arm will not be in optimal position without.
I flipped back to the images posted in this tread, and your ride height is quite low, so a spacer will do good.
You get your camber back to where it should be and lower control arm optimized, resulting in more stability in fast corners.

Another main concern would be the rear, you can't go too low without compromising traction and overall stability. In some sitations there is a significant rear-end-steer on these cars, and lowering will have an affect on the behavior.

Geometry can be corrected by altering mount positions, but that usually requires welding. (unless you find a genious way around this with offset/excenter bushings).
All- in- all, you have a really nice vehicle there.
