Seems like the last update has been pretty far back. Though nothing revolutionary has happened since.

I assembled and installed a new engine for the -92.
Now the bottom end consists of a -99 S80 2.9l block and rotating assembly, 850 flywheel which has been machined lighter, 215mm sintered 4-puck disc, 8V Saab Turbo pressure plate. I did some porting to the head, had a valve job done and it has been milled 1.22mm. Block has been milled 0.2mm to bring the piston a bit higher.

Visited a friend for the balancing of the rotating parts, he did the rods and pistons too. Crank was spot on, flywheel and damper needed only a little drilling, pressure plate needed more, rods and pistons needed some grinding.


Unsurprisingly the car feels like flying compared to the old with DMF More tuning needed and dyno time would be nice. Installed T6 injectors, they might be enough for E85 with a regulator "adjusted" to 4 bar. Had to swap a couple of bad looking coils because it started running a little rough after some harder driving while tuning.


"B6284T" got itself a 2L surge tank to help with long left handers with lower fuel level. Just have to box it some, drill a drain hole for leaks and make a bracket for the pump. Fits nicely under the trunk floor.



Wanted to reduce power steering force and tried to do it by shortening the valve spring. First try was ok and second one was better. Shortened in total around 2.8mm. Still would like less assist, but now it is not anymore over sensitive and without a feel.

Just removed the plug and pulled the parts out.




Yesterday it was time for VRCF summer meet on a track called Kemora and before that had to do some preparations.
Cleaned the interior, scrubbed outside and the wheels, swapped semi-slicks, etc. Repainted a small bit of engine bay because it had too thick paint and last summer oil cooler heated it enough to make the top coat peel off.

Second pressure pump was broken, lasted only a bit over a year. Lended it from another car, I think I'll install an AEM high flow pump. Installed a reipar kit to the left rear caliper because the wheel had a bit more brake dust than other side. Changed driveshaft rear u-joint, it had some steps while moving.

It would have been nice to have an uneventful trackday and be able to drive the whole day because it was my first time there. The first run went ok but steering pump started to leak through the axle seal. I was prepared that with a shorter belt and that was it. Took a couple short stints and after a while engine started running poorly, like starving and barely made it to the pits. Alternator decided to take a dump

Drove over halfway back with a battery from friends car and another friend borrowed a recently recharged battery wich helped to get back. Alternator started working for a while, then was dead for a while, worked again and died completely. On the way home swapped a fresh alternator from -92 and drove home(got to have two broken ones rebuilt).
Total driving distance of the day around 670km/419miles plus track laps.

Today was again cleaning day, two sets of wheels and the car. When does it end

Here is a crappy incar of a couple of laps. Positioned the camera badly, passenger covers the most and B-pillar the rest. Was going to drive some without a passenger, but well

They let you drive around the racetrack wearing shorts??

Looks like the car handles pretty well though!

Yep. Only mandatory equipment on almost all non-timed trackdays has been a helmet for now. Some quarter mile and standing mile events require driving gloves, long sleeve shirt and pants.

Handling is ok, semi-slicks make the car and driver look better Working power steering would have helped some and I didn't yet learn the track enough to push more. There is a pair of turns which you can drive quite fast, but I have to change gear in the first one and steering with one hand in the middle of the corner already got a little heavy.


I ordered new spherical bearings for the top mounts and those arrived today. Barely too late for the track day. They solved another thing I should have noticed before and it would have been nice to repair before the track day.

Installed new bearing to the right side. Outer shell had small vertical play and it had worn itself a little on the edges. Also the snap ring had some wear you could feel. Snap ring is a little narrower than a regular one, had to grind one to make it fit. Now it is nice and snug. The most sound came from loose shock nuts on both sides. Time and hard use have done what they can, can't believe didn't realize to check those earlier

These shocks have a very short and angled shoulder on the nut and with that even a little loose the strut can also move sideways. Goodbye alignment. After a quick all round check and alignment the front feels good again. And no extra noise.

"B6284T" has had new street tires for some time now, old ones were worn out. Same Hankook Ventus V12 Evo2 and same size. Looks like front tires last max four summers and rears two, how that can be?

Changed new oil, again Valvoline VR1 10W-60 with a can of STP Engine Treatment. Old Redline smelled pretty burned. Haven't happened before with other oil makes. Bought and installed an AEM "044" pump as a second pressure pump. Let's see how long it lasts.

Today I have owned "B6284T" for nine years. It's a long time for me, some might stay only a day or two.

Finally there was time to take it to a dyno. Around 18-20 pulls in the span of 2.5 hours. Inertia dyno so not enough load to wake the turbo properly but it's still something. And first dyno with the "HX45" after installing last year. First on 5th gear and later on 6th to get a little more load.

Slowly raising the boost, adjusting the cams some for a nicer curve and such. Running really rich because of the low load and losing power especially on top end. Torque was surprisingly monstrous compared to the power and previous turbos(and different dyno). New try after the dyno has a newer program and a brake.

1.95bar boost, engine numbers.


Some clips and a longer pull with going through gears: https://youtu.be/V3rXUrgwUgQ

Intake runners seem to flex a lot and its pronounced because I just remembered that the intake plenum bottom support doesn't have a nut. But they have been taking a beating for a long time and still have survived without a fault.

Other deals have been buying fiberglass front fenders for the -92 and Kent Cams VS5 valve springs to deal with the rpm and new cams. And bought a spare bottom end, had to pick up a complete car though

And all that through those skinny little rear tires?

Hasn't been a problem with bigger numbers before, why would it be now? Some plastic tires might not have enough grip

With K31 1.7bar was the limit on 3rd gear when making a full pull from low rpm, not so much when accelerating through gears or with semi-slicks.

Very impressed with the Volvo I6 with boost!
