finally, something that captures my interest

ssswwwweeeeet
Where did you find that blower and how much was it?

Grimmjar · 11-07-2007, 02:06 AM

it´s a new item from Komo-Tec for less than 2k euro. anywhere else it´s about 2600 euro.
it has a 70mm inducer and a 98mm compressor wheel. gearing is 1:7,5. max wheel speed is 90000 rpm.

Turbo-Brown · 11-07-2007, 02:25 AM

Why do you need a third TB to go infront of the charger?

The beauty of centrifugal SCs is that you can leave any throttling arrangements where they are because the compressed air is at liberty to travel back the way it came if needs be, unlike with the positive displacement SCs.

Or am I barking up the wrong tree?

Is it the BMW V12 you're using? Will be really interesting to see what sort of power it makes! One here in the UK made 365bhp with no modifications other than a mappable ECU which while not a massive increase, shows there's some potential

i´ll use the 3rd TB as a boost controll, like other tuner do.
i don´t know if i will need it but i´ll find out.

i hope i see aubot 700 Nm and 500 HP with 0,8 bar.
if it works well i buy some cams.

i have the 5.0 V12. the smalest one. even some chips do a god job on the NA engine. from 19 sec to 17 sec for the 0-200kmh sprint.

Boosted V12 in an E30 is going to be stupid fun. My ears would be bleeding with joy from listening to a V12.

Well if you like the sound of a mad BMW V12

I'm pretty sure thats a V8, even though the description says otherwise

I was thinking more along the lines of
