Required fuel for oversized pistons?
93 1.6, Wiseco Pistons, Eagle Rods, MS DIYPNP.
I have just had my bottom end built with oversized pistons (K554M785 Bore:78.50mm (+0.020 Bore) Compression Ratio: 8.5:1) and Eagle Rods. As the cylinders have been re-bored will I need to change the required fuel in MS? I would imagine several on here have used the above set up so if I do need to change the req fuel I would be grateful if someone could tell me what it should be as I have no idea how to work it out:dunno: Barry |
Increase req fuel by the same percentage that you have increased capacity.
That wont be perfect, infact most likely a little too much but when you do the calculation and find you have increased capacity by like 2% you will realize how little req fuel will need changing. Dann |
The stock displacement is 1,598cc, with a bore of 78mm
With your 78.5mm pistons, the displacement is now 1,618cc, an increase of 1%. So either: A: multiply your Req_Fuel value by 1.01, or B: Forget about it. This is a trivial change. |
Thanks guys, I will leave it as is :)
