What is safer for our cars in the long run - 10 years 60,000 miles


CAI with an aggressive canned tune
F/I (6-8 psi) with conservative dyno tune.[/ol]

Thanks

RE: What's safer
 

I would say that either option would be safe and perfectly reasonable, assuming that you do your normal maintenance (change your oil & filters, etc.)

However, technically, whichever route puts less stress on the engine is going to be safer. Thus, the non-supercharged route would techncially be safer....though expecting 60k miles with a conservative dyno tune is perfectly reasonable.

RE: What's safer
 

everything depends on the tune,

you could buy a blower, stick it right at the 450 HP mark, and tune it damn good, and it will last longer then a stock 4.6 that has been leaned out to no end.

RE: What's safer
 

it really depends. but, all things being equal, i'd have to say the F/I would put more stress on the engine, so over a long period of time, it might be a little more wear and tear. but an aggressive canned tune is never a good thing; whats aggressive for one car might be too much for another and cause problems.

Safe= keep it stock

But few of us enjoy taking it safe!

60000 miles in 10 years!!!! That is only 500 miles a month!!! Dude I do that in about a week and a half!!!! Holy crap!!! I take it this is your weekend car????

But then again...if you blow the bottom end out with a blower...well then you just get the FUN of putting it back together stronger and then you can run even MORE boost!!!!!!

Go for the blower!!! I mean if your only putting 500 miles a month on it then you should make those 500 miles as fun as possible!!!!!

25k miles on my car 15k on blower. Only oil changes no other maintence no problems

RE: What's safer
 

Thanks for the comments everyone.

The car in question is an05 V6, it’s not a weekend car, I just do not live to far from work I guess.

I see a lot of V6 and V8 owners putting on a CAI with what I perceive to be an aggressive canned tune, maybe they are not that aggressive though. Now this is only good for about 20 rwhp VS. a blower on low boost for ~70 rwhp. Now if reliability is the same why not go F/I except the money of coarse.

Also can someone explain the difference between a good tuner and an average tuner (human not hand held)? If you do enough pulls on the dyno, can any average tuner get your car to the same place that a good experienced tuner can?

Really try an xcharger. It wont open boost unless you are at 3/4 throttle or somewhere around there. Doubt it will hve any extra strain on your engine.
