I now that forced induction can decease engine life but what about bolt ons. Wouldn't they increase or have the same engine life as a stock car. It seems like all bolt ones relive the engine of stress instead of putting stress on it like FI. Like a full exhaust and intake allow the engine to breathe better and electric water pump and udp's allows it to spin more freely. I'm not sure about upping the timing for a tune. What do you guys think?

 

I'm currently N/A but I think that alot of it is going to be based on what kind of driver you are... lets say you have a bolt on GT but you have a lead foot with the pedal always floored... you bring it to redline bouncing it off the limiter constantly... powershift frequently, etc... then compare that to a FI stang that really doesn't get on it to often. Well the bolt on GT will have more problems just cause it's driven so mush harder... FI -- although harder on your engine life slightly so I hear... still isn't the worse thing for you when compared to a situation like above... combine both with the **** driver mod then you're both in the boat ... [8D] this is of course my opinion ~ J

 

I hear what you're saying, but a lot a variables.. driving style, maintenance, strength of the internals, boost level, tune, etc. I think in the end you can't really say that FI is or is not more durable than NA.

That said, I've been considering FI next year, but part of me still likes the idea of an NA motor built out to 450-ish RWHP - cams, bore and stroke, the works.. I guess in my mind, with FI you're taking a motor and making it do more work, whereas with an NA build you're, in a sense, increasing the capacity of the motor itselfto do the work you throw at it... then FI later and you've really got a beast. Hmmm..

 

The bold is the reason that I'm still N/A for right now ... I agree with you for the most part but you always have to consider varibles as we all drive different -- different mods, etc.Varibles will always play factor
