Hi all,
I'm rebuilding my Daihatsu 1.6L HD-E for supercharging to go into my Feroza 4x4.
Having a bit of a disagreement with a mechanic mate and looking for some other (preferably qualified/knowledgeable) feedback please.
Please bare in mind that this is for a 4x4 which is also my daily, not a racing car so I'm aiming for drivablity in real world conditions. I've gone with blower instead of turbo as I want instant boost and linear throttle response (and if I can take down some young blokes from the lights that'd be a bonus ). Mechanic mate keeps trying to push me to go turbo but tbh I really don't think it's what I'm looking for.
He's also giving me grief over my plans to lower my CR.
I've done the CR math (with pistons recommended by a couple of guys who are getting close to 300hp out of the same engine - which is waaay more than what I have planned) and have some figures that should be in the ball park.
Factory CR = 9.5:1
Static CR (with Nissan GA16DE pistons) = 7.17:1
+Boost - 11.38 PSI = EFFECTIVE CR = 12.72
Does this sound workable or am I missing something?
Practical feedback would be really appreciated, cheers.
