Not necessarily. I know when I put my cams in my evo, they were super aggressive (the 3rd from the top). Yes it had a lopey idle to it, but all you had to do was advance the idle timing a little bit and it smoothed right out. If you retard the timing tho, it just made it sound that much more mean (at least that's what I did for kicks and giggles, then put it back to a nice sound idle (at least to me)But wouldn't installing aftermarket cams make it sound like a carborated hotrod?
They also aren't supercharged like the GP GTP's. The GP GTP's were the 3.8 supercharged in the late 90's, 3.4 DOHC in the mid 90's and 3.1 Turbo's in the late 80's. That is only the GTP's tho, not the GT's and SE's.Yep. I was once looking into an '06 G6 GTP 3.9 V6 w/F40 tranny. I was wondering why an engine of that size only made 240hp. Turns out it's an OHV. I wasn't impressed.
