Cylinder heads, injector size , type & Set up

It would be useful to get some bike engine performance figs to see how they compare.

Great, so there's a ref point.

Sam, were you working off the 5252 rpm intersection principle?

 

Whats the bore on a VW 1.4L 16v polo Engine ?

must be arround 75mm

1,390 cubic centimetres (84.8 cu in) inline-four engine (R4/I4); bore x stroke: 76.5 by 75.6 millimetres (3.01 in 2.98 in), stroke ratio: 1.01:1 - 'square engine', 347.5 cc per cylinder, compression ratio: 10.5:1
cylinder block & crankcase

Engine Size 1390 cc
Cylinders 4
0-60 mph 10.2 s
Power Output 100 bhp
Valves 16
Torque 128 Nm 94 lb-ft
Top Speed 117 mph

 

There's a bit of crossover here with the 9A vs ABF thread, so the next question appears to be what rod length the bikes run.

 

Rod length isn't relevant as only the head would be used on a VW Block with TB's and external Injectors

High reving engine with external injectors for max atomisation.

would be nice somemore 9A & ABF Engine pix with external injector set up

 

Oh yes, I realise they're just able to use the heads.

I think I'm inadvertently wandering into "how'd they do that" territory re: the rpms. Off topic!

 

The engineer who works on the Red MK1 Polo gave use all the info

High Revvvvvvvvving motorbike head ! its the future .

Top secret ( I've looking for a MK2 Polo Coupe for my next Project got tig welder already)

 

I'm guessing the heads have huge flow, but then started thinking onto the bottom ends vs the car blocks. Just thinking in terms of a getting a better understanding.

(I personally hate the bike engined single seaters that are seen on sprints and hillclimbs btw. They sound stupid !)

 

just for reference an R1 has a 103mm rod
