Being a total gearbox dunce, can anyone help with the following query.
Had some cam, exhaust manifold, and head work done on my Astra which is now giving an offical 173bhp at the flywheel.
Low end torque has improved, Mid range has totaly rocketed as i was hoping it would, and top end has more pull than before.
But top speed hasnt improved. Wasnt expecting much, but wondering why a few mph,s aint forecoming.
I havent really tried TBH, i dont beleive in driving like a moron, but on a quiet late night motorway, its sometimes nice to see what the car can actually do.
Anyway, could this lack of top speed improvement be anything to do with the CR F18 gearbox im using, or simply because i got all the torque where i wanted it. Between 2-5k.
Im not hitting the red line in 5th, it edges just over 5.5k, but because it feels like more power is remaining, i cant figure why it wont edge on further.
Its almost like i have run out of gearbox potential if that makes sense.
Anyone wanna put fingers to keyboard and explain for me.
Sorry for being a pratt if im missing something obvious here
