Stacking will definitely require more fuel.

 

Literally my initial point chuk haha. No worries man. Sorry if i wasnt clear about my mods on deck.

 

To clear things up a bit. If you aren't running lean, there can be an advantage to the bigger injectors in that the duty cycle will be lower and thus may add some reliability in that area, without actually increasing performance. Your choice of the 178 pulley is good, with the 181 crank pulley and that SC pulley you will be exceeding the safe limits of RPM on the SC pulley bearing.

 

Thanks for the heads up on that. U just made my decision very easy.

 

You're welcome. If you can find it 32 CRAZY posted a chart with much good info on the percent of overdrive of residuals and rpm of SC pulley with the various combinations, gains, etc. It's worth a read, he even listed the members who had each of these setups. Good luck.

 

Interesting. Id like to read that.

 

BrianBrave did this chart.

 

I may have given false info on that chart, it might have been BOOSTMONKEY, I took a cursory look but didn.t find it immediately but a more thorough search will turn it up.
