I wish i could afford/was clever enough to get it revving that high ^
Bit of a contradiction in wanting to build a high reving enigne at low cost but I can see the apeal.
Matching the laider to the revs is just a question of pulley size; you need to go bigger. Also the standard G40 fuel system, inlet & exhaust setup on a 1 litre will flow plenty enough. In fact if you can just increase the revs by 20 - 30% and match the charger revs accordingly with a remap or aftermarket ECU you should easily make the same power as a G40.Could you stick a G40 head on there too?
Then you need to look at what else is over reving and becoming stressed, Oil & water pump (cavitation?) Distributor. Look for increased wear on all the bearing. Choose your gears cairfully too
I know what your saying regarding cost and revs.
This is a bit of an experiment really.
So far I have in the G40 parts bin:
PY block, pistons and rods.
2G crank
G40 oil pump (anyone know flow rates on this, is it in the haynes?)
G40 head
Choice of camshafts either PY,2G,MH or 3F standard or a 272 Dbilas.
3F inlet manifold
G40 Exhaust manifold and downpipe.
A couple of worn G-laders (will be getting a re-build on one if they're repairable).
G40 fuel pump
GT gearbox - may need revising.
Ignition may well be something that needs alteration in time.
I read that the standard hydro buckets are good for 8.5K revs? I see Bar-tek tuning do buckets for over these revs.
Doubt i'll be pushing past that at this stage.
