Hi welcome to the site . Check out the brochure section for a figure


Hope this helps - Jap cars are mapped to a higher ron value on the fuel so you may not get this in the country running on 97 / 8 ron petrol anyhow. BUT you could add a few tweaks to exceed the figures!

280 is the quoted figure for just about all of them

In reality all of the standard ones that i have seen on rollers actually make around 300 ish
