I'll reserve my opinons, but there are major benefits to creating the correct boundary layer thickness, which rifling would kill in terms of flow and suspension.
you need to check for rocking at 12 and 6 and 3 and 9, just 12 and 6 and you could be looking at worn bottom ball joints or top mounts, loose hub strut bolts.
Take the wheel and disc off and wobble the hub face itself, then you will know if its the bearing.
I've never seen tracking pull...
Financially no, only for the hardcore.
New crank, rods and pistons, block bored and a different head gasket are the basics.
Technically you dont gain peak bhp but you gain potential bhp as you actually build more torque and lower the point of peak torque and point of peak power. This...
Any flow specialist worth his beans will tell you that any tubulance in the actual port is just using energy and slowing flow, introducing a chaos factor as that area will react very differently at differing rpm and velocities.
All effective swirl is created with port entry angle, port...
saxo vts will be the fastest and cheapest. If you get round the stereo type they are fantastic cars. 106 and vts are exactly the same cars....but the 106 is a tad heavier, although nicer inside and out.
8v's have built the reputation of being more torquey because in std and mildly modified trim, they run much less radical valve timing events. Couple this with average port velocities that are higher at lower rpm's and you get an engine which lends itself to high VE's at low rpm's. Thus it...
even then, its apalling.
I specialise in flow development and i liken the vag head to reproduction toilet bowls. It takes serious money to get that thing to do anything decent.
meths is stoich at 6.4:1 so you have to tune differently for AFR and EGT, apart from the nature of the burn you dont have to build the engine radically different.
But, in the future, i'd say hydrogen is going to move forward and/or fuel cells.
electricity isnt there yet for commercial...
