My V4 has a K&N, single choke Weber, Jetex exhaust and Luminition kit, it goes really well. I am planning to rolling road it soon as I want a bench mark for when the 1740cc lump goes in, when I do I'll let you know what those mods produce and also how the 1740 goes later on (like stink I hope!!!)

Engine;
Solex 32/32 on SR manifold with the Saab airbox containing a foam filter (note all inlet manifolds need matching to the port areas as they are restrictive). Bosch triple spark plugs for longevity and a slightly larger plug gap seems to give better performance. To help the top end performance a home made s/steel exhaust has been made.The front pipe uses the std hole in the engine bay and meets at the bulk head in a 'Y'.The main pipe is 1 3/4 inch with a home made straight through centre box and a Volvo box on the rear.
Suspension;
Red max four dampers, Later front springs and anti-roll bar from a early car on the front. 1 deg negative camber and plenty of caster at the front. This setup gives a good increase in torque and therefore drivability for a small out lay.

Road going class sprint/hillclimb project car		 Richard Says -
Engine;
1815cc, 1700 crank, 93 forged pinto pistons (pinto piston have a higher compression height, V6 items lower the compression therefore have a lower compression height). I use V6 Scorpio rods and ARP rod bolts (see Burton's catalogue), these rods have more meat around the bolt holes/big end which is where they always fail in competition (the rods go up in beefiness and weight in this order V4 1500, V6, Scorpio. You must also use the ARP bolts above 6000rpm). The block is copper ringed and runs a compression ratio of 10:1 with the std chamber sizes ( a good head gasket can cope with a compression ratio of about 10:1 and the opening up of the chamber as SR manual can only be done if you have dome top pistons). The head is a single port big valved fully ported head all machined by myself including the seats for the valves. Coupled to this is an aluminium rocker support to stop the rocker rods from flexing at high revs. The cam is a Saab 7.6 rally cam operating with lightened lifters and the engine sucks through a CT inlet manifold and twin webers. To cope with this the oil pump has an uprated spring to aid oil flow and a oil cooler is fitted. The engine should produce between 130-140bhp if I have got it right.
Suspension;
Saab works rally springs front and rear ( rear are progressive). The wishbones are triangulated and seam welded and the front spring mounts have a steel wedge welded to the underside to stop them from collapsing ( this is essential with these springs ). The upper wishbones have been modified so more caster can be added. All the suspension bushes except the rear centre bush have poly bushes. The damping is via red max fours. Shell; The sills have double the originals welds and strengthening plates have been added around the holes for the steering arms. A ten inch long angle has been welded at approx 45 deg down to the front upper damper mount to stop the inner arch from flexing. Other areas that have been strengthened are the feet of the front suspension towers and the middle of the channel at the top of the front inner wing.
Brakes;
Std Saab calipers with mintex 1144 pads at the front. At the rear, std wheel cylinders and Ferodo AM8 shoes.
Gearbox;
Spec 1& 1/2 with std crown and pinion, no LSD. The gear box needs extra supports as the engine runs a through the floor exhaust so the stay can not be used. A bracket from the floor that picks up the engine to g/box mounting screws is going to be made. A bar with a hole in it will be positioned behind the gear box rear mount bush to stop the gearbox pulling forward under braking. Clutch is an uprated spring clutch with a cerametalic padle plate.

The car has a similar spec to the above but has the following differences:- The shell is seam welded and has a 6 point cage, all the metalwork for the rear seat has been removed and Perspex windows have been added to save weight. The engine runs through the Saab moose horn inlet manifold and uses a Kent rally cam (V6 profile), it will not pull below 3500rpm and at 4000rpm is like a turbo has kicked in up to 6700rpm (in other words its very cammy and not usable as a road car unless you are mad man/woman). The gearbox is a spec 1 on a std crown and pinion with an LSD. The LSD in my opinion is only for competition use at if used on the road will catch you out if you are not concentrating ( Talk to Simon Gaden about them, he crashed Andrews Sonnet into his Land Rover dealership and he was only setting of to test the brakes). The engine produces 147bhp and the gearbox needs a rebuild after 4 events!!! The dampers are the AVO type and these have been OK. The front springs are 395 lb/inch and the rear 30pc uprated. The clutch is a Highgate diaphram clutch which is to be fitted with a cerametalic padle plate (Melv might beable to supply these now?)

My car has a 1740 with fast road cam, stage 3 heads, 32/36 weber, steel timing gear, oil cooler and simons exhaust system, I dont know that much but I am happy to let anyone know what I have, there are a couple of guides I have taken from the SOC from years ago which are very good and i can copy and pass on. It is my understanding that most significant/cost effective performance to power is through improving the breathing i.e. exhaust and carb, this alone can seemingly give about 15bhp, as you will know free flow exhausts are easy enough to obtain as are suitable twin choke webers, the big stumbling block is the manifold, I dont know if anyone has thought about trying to have copies of the old adaptor plates made up but i am sure it would not be beyond the scope of a few dedicated enthusiasts!.
