Strokers and gearing
DISCLAIMER - I am not an expert on car tech, by any stretch of the imagination, so be nice!
The debate of big turbo stroked vs non-stroked is well documented. My understanding is that, in general, a stroked motor will hit peak boost earlier but have a lower max RPM, considering all other mods equal. Typical for road courses, etc. A built 2.0L will build boost later, but given a higher max RPM allows for more 'on boost' RPM's, making it good for drag.
I was wondering if you look at it in terms of MPH 'on boost' vs RPM 'on boost' and look at a taller aftermarket gearset, could that give a stroked motor a more usable powerband, again in terms of MPH, not RPM (I understand the relationship, but this helps me exlplain it better).
I'm assuming a change in gearsets won't change your peak boost rpm - is that true?
If so, a stock tranny that would top out at 92.7mph in 3rd gear could see 100+, giving it a more usable powerband on a stroked motor?
Ok, I'll stop rambling...discuss!
