Hmmm... A8s? Here in Sweden, the norm is to run A7s in a stock 2-stroke. But maybe the lower octane fuel in the US has something to do with it.

Default 95 stroker

Hi Funkman,

good to hear Tim Green is still efficient!
The starter solenoid and copper headgasket are on their way along with the door/window seals.

I'm in UK, Scotland Well its not exactly a stock engine as well, it has a Lumenition electronic ignition, plus it will be tuned fairly soon as well. A8 are equivalent of the Bosch performance ones listed originaly in SAAB manual for fast or hard driving. All depends how you drive :wink: I dont't think Strokers were ever ment to be driven soft.

Good news today for a change :wink:
Got a solenoid, managed to asseble the starter back, got it tested - it whizzzzzed into life with turbine smoothness and jet like eagerness. But unfortunately I managed to snap one of the important bolts so waiting for a spare starter to arrive.

Sent the coil back to Demon Tweeks, recieved a replacement today and it's a wrong one Again This time they did send me an epoxy one but again for 3ohm instead of 1.5ohm.
Grrrrr

Well... IT'S ALIVE! ALIVE! Installed the starter, new plugs, new HT leads, Flamethrower racing coil. It was running like never before, seemed like all the troubles were gone. But knowing my luck I was prepared, and during the testdrive ... middle exhaust bracket broke, it's just rotted away Now exhaust dangles violently, probably dangerous for manifold as well, since vibration might cause cracks. Plus after the testdrive all the water in the radiator turned into a grey sour cream Will have to clean the cooling system properly, possibly recore the radiator or get a new one.

Oh well ....

At least progress is being made!
A modern core in the radiator will be a huge improvement.
Maybe just carry out a temporary repair on the exhaust until your 2 inch system arrives?

Finaly made my decision - rebuild is inevitable so it's better to do it sooner rather then later. After a 500mile journey with blown headgasket, dying engine and box it arrived to the place of future rebuild! Hurray!!!
Lost all the gears apart from 3rd and 4th, so my
0-60mph was probably 20min, also I couldn't reverse, so every "pit" stop had to carefuly planned
The main thing - I made it. Rebuild will take 7-8weeks.

Welcome back, funkman! Your merry banter has been missed. PS: there's a 2-stroke engine and gearbox for sale in the SOC site adverts section and a nice-looking 96 stroker for sale in Classic Car Weekly (Devon).

I think I saw that Classic Car Weekly. 1964 in good condition for 1995. That must be a good price for a Stroker.

After a long break it looks like things are happening again. Engine is being rebuilt as I write these words Bodywork, suspension and other bits and bobs will be looked after as well. Not as fast as I hoped but faster then most of the rebuilds.

So hopefuly it will be finished for beginning of summer :wink:

P.S. looking forward to 80bhp 8)

Omg... 80hp?? What are you doing to that engine?? What kind of carb? How much porting?

That degree of tuning on a SAAB 2-stroke usually results in close to zero driveability, heck, even 55-60hp is bordering to what's comfortable to use in traffic - that's when they start protesting and fouling spark plugs when idling at traffic lights.

Are you planning on a SP2 gearbox too? If not, you should... the very small rpm interval that such a heavily tuned engine has power within makes stock gearing very difficult to drive, and not very fast.

Carburators will stay the same apart from bigger jets, better floats, butterfly spindles etc (from classicsaabracing.com) and possibly slight air filter modification. Petrol will be supplied by electric fuel pump.
Ignition system will be upgraded to give maximum performance.

Crankshaft will be rebuilt with modern moto-racing components. The stroke will be lengthened and compression raised.

Can't answer the question about porting since it wasnt discussed yet.

Exhaust system will consist of: tuned front box (classicsaabracing.com) + 2" exhaust system from Swedish Saab Club.

Suspension: Rear shocks will be changed from lever arms to standard ones, stiffer and slightly shorter springs will be installed. Front brakes converted from drum to disk.

You are right Enor I probably will have to use SP2 gearbox but the aim is to produce the car as drivable as possible in normal traffic. Its all the matter of balance and as long as you balance your engine power with other componets everything will be ok. The car is in the hands of Wizards of Saab World so I'm sure the final product will be amazing.

All i'm saying is, 80hp out of that engine is a _very_ high degree of tuning - it's an aspirated engine and it's tuned to the point where it's more than doubled its stock output.

Trust me, it's _not_ going to have a lot of "daily driver" potential if it has 80 hp... it's a full-spec rallye/racing engine (on par or slightly more powerful than Eric Carlsson's Monte Carlo winning engine) and as such it runs fine as long as you're constantly pushing it hard at 4000+ rpm; but let it down and it'll run too rich and send its spark plugs to the promised land.

Plus, to me 80hp using stock carbs sounds incredibly over-optimistic. But this is a triple-carb 1966, right?

yep its a triple carb. Drivability is an important issue since I'm planning to use the car so we'll have to experiment and find an optimal solution.

By the way one of the ClassicSaabRacing cars produces 119bhp, pretty scary eh

If you plan on using the car in every-day traffic, settle for 55-60hp max. It will still be a bit nervous and quirky at that point, but bearable.

COR!

Wish I had the time to do that to it Funkman, but then I would never have sold it! I already miss it!

Sounds like it will be a beast, really looking forward to seeing it when it is done.

Got the report back on my engine and box:

//Gearbox:
Gearbox is past redemption, not a single part is salvagable

//-----------------------------------------------
Engine was dismantled. 70mm bores (Std dimension).

Crankshaft:- big end cages split, main bearings noisy. Requires overhaul.

Pistons:- some wear. in average condition.

Block:- excessive wear present in the middle section of the bores making rebore necessary

Carbs Too much end float on the throttle shaft, requires rebuilt throttle housing or changing for less worn unit.

Distributor: - Too much side float on the rotor shaft. Replace (Transistorised ignition fitted?)

Water pump:- not checked. If it leaks it can easily be changed at a later date.

Clutch:- Disc is oil soaked. Recommend fitting diaphragm type of pressure plate and replacement disc particularly if more arduous motoring is envisaged.

Fuel pump:- not checked. Recommend fitting modern electric SU type
Possible options
If more power is required this is the time to think about options such as:-
XP long stroke crank
XP gas flowed throttle housing
Rebore and fit Hepolite pistons to next size 70.5mm or bore out to 73.5mm using XP forged pistons.
Fit XP crank shaft torsion balancer pulley for reliability.
Replace exhaust for performance system, XP front muffler with 2inch pipe and rear muffler from The Swedish SAAB Club shop.
//-------------------------------------------------

Good Lord I don't know how that car was going at all. Recommended parts alone are approx 1500

Sounds as though you should have bought that stroker engine off the SOC website a few weeks ago!!! I have a spare gearbox in bits if you want it. Chris Partington has "retired" but can be contacted via Highgate Saab - a rebuild is around the 450 mark (there's a recent thread about this somewhere, either on saabcentral or saab-v4.co.uk). Keep smiling - it's only money and time .....

Who do you think are "wizards of Saabworld" that are rebuilding my flying machine :wink: Im not depressed at all about the costs, in fact I'm happy that for once something is going to be done right, had too many unpleasant experiences with my classics.

It's not the rebuild but parts mount up the costs here, We've decided to go with SP1 gearbox and 8\39 ratio, which will increase costs further but I budgeted around 2500 for this work and if realy needed will stretch further (hopefuly 2k will be enough).

I don't intend to sell it ever and looking forward to it when it's finished.

P.S. it will be the best 95 Stroker in the World
