Observe.
Until 5700 or so RPM the i/h/e plot is dead even with the plot of the same motor with Crower 403's. 135 whp is about 15 more than stock. So yeah, those first 15 hp gained or so cost you a grand and then it's only 2 grand more to add another 70 ponies. But hey, those extra 15 hp aren't unnoticeable and you're still only paying $1000 instead of $3000. Basically it comes down to if you want to spend a grand and call it quits or if you want to go for huge power increases and spend three times as much.
Now let's keep it mature here people.
Thank you. This thread is so long because people are *****ing and whining and adding irrelevant info instead of answering the question.
IMO I would say it's worth it if it's worth .3-.4 seconds off a 1/4 mile time. Does anyone have more dynos or real world experience instead of bullshit and guesses?
