Thread: Ashcroft Force 9, is there anything better?

The only negative I can see is the engine weight. But I am assuming the LSA is a cast engine block?

Other then that I have been watching the firestorm builds over at LRA and they are pimp.

Aluminum ..yes they are unreal!

Was refering to the 2inch sump, would that hold enough oil etc for the engine

It's just a collection pan, you run external tank and pump

For the India being sloshed around could you not retube gu gear to use off the shelf innards (albeit cal gear etc)
Abs is a workaround but were talking massive electrical changes just with ecu intergration

even with Ashcroft gear in the front the crownwheel and pinion are going to hate over 500hp. Even pegging the diff will only help so much

Thats what im afraid of, but for the front i think we will try the rover centre with ashcroft everything pegged and hi tough, if something goes then plan B which will involve the 9" up front

Rear at this stage is 9 centre, rover tubes, hi tough axles 31-24spline, upgraded flanges, then if axle fails at 24 end move up to 35-35spline with upgraded spindles , bored out hub with bigger bearings and 35spline flange.Unless someone can confirm where i can currently buy spindles and flages now to suit?

You'll have heaps of clearance for just about any diff. There's an external oil pump and I think 5 scavenge sections, these collect oil from all around the engine. As an example in a race application I'll have them front and rear of each head and 4 or so in the sump. This sends the oil to a collection tank which has to be designed correctly (your first downside). It will de-aerate the oil and start to cool it down. The tank for your application will need to be custom made/designed to fit and work correctly. The benefit is you run a lot more oil so it's cooler and in a regular application you may be able to extend change intervals. From there, it's pumped from the tank by the pressure section of the pump, drawn through an external cooler then the pump an into the engine oil circuit.

The pump should bolt straight onto the engine and the stock factory system was run in ALMS and at Le Mans so it should be fine. There's a heap of lines to organise but again, as it's factory it'll be neat and you won't need to make up much If anything.
