How Many Rwkw On 98Ron.

[mikeBF2TLS]

Soooo,

In a standard BF2T with no mods on 98 ron, what are the power gains? Has anyone out there in the XRT ether sussed this out?????

[ms700]

I know its kinda unrelated, but ive got 570 at the back of the XC, and that's with 98.

I reckon its all in the tune.

Its a combination of the two, bigger hardware can support more power due to less timing advance etc etc afaik

Looking up some old graphs, for comparative purposes:

638rwkw Nov07 with C16 ... tune I ran a 138mph at wsid on street tyres

... then various other mods

614rwkw Feb08 with 98 BP Ultimate

637rwkw Jul08 with 100ron shell

Same dyno, so wheel slip and other variations bypassed.

It comes down to the efficiency of the vehicle setup, and having dyno equipment to measure combustion efficiency.

You can make good power with 98, but it just doesn't feel anywhere near as good as the 100 that Shell withdrew from the market.

For daily driving it's more realistic to detune somewhat, due to 98 fuel variability, and in my case avoid writing off another car.
