Re: Power mods for the I-5
My reply was toward power mods for the H3 and having the ability to gain over 20% with bolt-ons. Based on personally observed data, I said that you can. I presented someone elses dyno graph that shows a 15% increase with only an airbox, exhaust, and tuning.
Here are bolt-on mods that if all done, that will increase the HP by more than 20%
1) Well designed cold air intake
2) Ported throttle body
3) Under drive pulley
4) Electric fan(s)
5) Header
6) High flow cat and piping that doesn have the two crush locations like the stock piece
7) Cat back exhaust
8) Custom PCM tuning
9) Electric water pump
If properly done, there will be no change in emissions, more HP, and better fuel econony.
If you have a different opinion that's fine.
