I have an appinion here....
Now the fastest sweede is frederik and his engine is an 8:1 kompression with maksimum portet head, custom intake, custom exhaust with an garret GT-42 turbo and custom cams(wild) he runs with 95ron and 1,5 bar off boost 505BHP, and 734BHP with racefuel and 2,5 bar off boost, but it has boost at 5400rpm.....
It works like HELL, what an engine.....


MY engine is 7,2:1 komp 2x bd14, portet head for low down torque and upgraded T34 turbo, and with 98ron and 1,6 bar it gives max boost at 3400rpm and holds it to the limiter...
It has the best off both worlds, and has drivability like an GRP.A rally engine... I LIKE

Forgot to say the my engine produces 507nm at 4460rpm.... and 385BHP at 6600rpm(limitor set WAY to low)

Now the point is that the engine works like you set it up, both the cams and the mapping, so go for that insted...
