Race fuels ..

Post by ALFA GTV6 GP »

My new engine will have 12.1 compression ratio and I will need to run 110 ron fuel.
I am considering using Martini super turbo 1400 racing fuel (previously called M110) with BP 100 anyone used this fuel before, thoughts feedback?

All feedback appreciated ie other fuels used and combinations to achieve 110 ron.

Thanks John

What kind of camshafts do you plan to use if you need 110 RON with only 12:1? Sounds weird. And why chose 12:1 if there is no fuel avail?

My engine will be a 3.0 12valve race spec.

Yes AVGAS is a possibility

Mats
Fuel is available we have BP 100 at some service stations and I can drive to the airport and get AVGAS.

The Cams are full race cams not my design so I wont post the stats
without permission.

My engine builder has specified I use 110 Ron.

With fuel injection this motor configuration was good for 310 bhp.

I am going to run carbs for approx 280 bhp 270 lbft torque.Torque curve should be very good between 3500 and 7000 making for a very easy to drive race car.

with race cams and 12:1 CR you shouldn't need race gas.

I have 12:1 in the GTV and no problems using pump gas. I can even use mid octane (95) insead of high (98) if I need to.

On the other hand my brother's old Spider needed 98 with only 11:1 CR as the exhaust cam was stock and intake very mild too.
