[silentdub]

How much HP does the little 1.4 have anyway? I think the 1.6 stock was about 53 or so.

Hi
in the garage there is a couple of other cars.
volvo 242 it´s going to be a group A replica.
Behind the Saab viggen there is a volvo 850 stationvagon with 508Whp.
beside the the 242 it´s an audi s2 quattro tuned to 650 whp. fastest in the garage.
next to that its a nissan skyline.
another saab turbo and a volvo 745 transformed in to a pick up.
Probebly the most modified volvo in Sweden.

If u intrested, you can find more pics of the making of the pickup here:

wow you guys are serious about fast cars haha  what engine is in the 850 wagon?

Now the car is assembled and the performance pump change started.
A very hard working period, I can promise, but now you can drive the car in the rain, This update has been hard,working around the clock more or less.
But just wanted to show how the car looks now.

Please enjoy !!!!!!
First car last summer.










What do you think?
Will all the work be visible !? : thumbup:: D

A small clip from dyno-day.
IC blown and exhaust pressure problems.
Max presure 2.6bar.
Not the best result, but a start, anyway here it is.

What turbo are you using? Must be miles away from efficient at that kind of PR....

[polo_td]

It´s a turbo from BMW 525 TDS.
And its way to inefficient, as you say.
Building counterpressure after 2.2bar.
Just ok to go up to 2.4, after that its just waste.

Hi
Need some info of wich turbo i can use instead of the Beemer one i have now.
Hopefully there is one with the same flange.
Sorry but i dont know the number on the turbo, but it is org mounted on bmw 525tds -1992.

Need one with faster spoolup and långer performance so to say.
Now it "dies" after 3600 rpm.

looks like the mercedes benz 45 trim t3 wouldn't be too awful, with your smaller displacement you may want to swap for a smaller a/r exhaust housing.  it looks like it could get you in the 150hp range

use 18:1 for a/f, .36 for bsfc, and some where between 75-80 for volumetric effeciencies.

Interesting site in the link!!! 

How about watercooled IC.
Any hints about this?

I think i will seperate the waterkooling inbetween the head and block/bottom.

Adding an extra pump just for the head itself.

Do you guys think its nessesary to have 2 seperate rads in this setup.?

thomas

[RabbitJockey]

yeah that site is awesome, saves you a lot of time, and its nice to just scroll through and see what might work.  air to water intercoolers are supposed to be better right?  And yes it is necessary to have 2 separate radiators with an air to water intercooler.  or did u mean one rad for the head and one rad for the block?

I have an AWIC on Jezebel, works great.  However you need a completely SEPARATE cooling system from the AWIC, it does not use engine coolant in any form.  It has its own radiator, pump, reservoir, etc.

Everything I put in for our 1.6 was to the left of the surge line? Is that normal or how do you use that thing?

yeah thats the problem with the 1.6, no displacement, ***ty flowing head, and can't rev much over 5k, so most turbos surge with it.  aaz and tdis have much better turbo choices due to the larger displacement, but most tdi people want to run little baby turbos, no wonder it took a decade for a tdi to break 200whp haha.
