Yeah, voiding the warranty isn't worth gaining a little better acceleration. I might go with a lower restriction exhaust system before the warranty is up...if I can find one that doesn't make the 4cyl sound like a riceboy racer.bballr4567 said:Im going to do a DIY CAI but that is about it.
Warranty is too valuable to go screwing around with it anymore than that.
Intake and exhaust should be done at the same time for performance gains.kupiheab said:I was thinking of making a ram air into the factory air box, with a drop in k&n filter and punching out the MAF. Then crossing my fingers and hoping that it makes a little difference. Then down the road possibly put a magnaflow muffler under her.
the same time!?!? lol....it doesnt matter....modern computer adjust almost instantly.....gearhead said:Intake and exhaust should be done at the same time for performance gains.
That's what we did in the old days and theoretically I don't see how anything's changed.
I mean if you're going to stuff more air into the combustion chamber but can't exhaust it fast enough, you're developing back pressure, which isn't going to accomplish anything except maybe confuse the ECM, right?
Hmmm, learn something everyday.gar187er said:the same time!?!? lol....it doesnt matter....modern computer adjust almost instantly.....
Tell her you need it so you can drive her to the jewelery store faster!kupiheab said:That is correct. You do need to open the flow on both ends but you will gain some power just opening one side just not the peak power. Only reason I am waiting on the exhaust is b/c I have to talk to the wife about it.[/color]
more air=more fuel too.....thats the reasoning....your not just putting more air in and running lean, the computer compensates for it, by upping the fuel mix...gearhead said:Hmmm, learn something everyday.
Still don't understand how stuffing more air into the intake will increase performance (unless it's cooled a bit...maybe yes).
kupiheab mentions "punching out the MAF", the Mass Air Flow, sensor.
What effect that has on the ECM, I don't know.
All I'm saying is an engine is like an air pump, if you don't have the capacity to exhaust it fast enough, what's the point of trying to stuff more air into it as there's no where for the extra air to accumulate.
You'd simple be compressing it somewhat.
When I was a street rodder, it was common knowledge (proven on the dyno) that you weren't going to gain much power by increasing airflow in unless you open the exhaust at the same time as well.
I understand 100% what you're saying...but.gar187er said:more air=more fuel too.....thats the reasoning....your not just putting more air in and running lean, the computer compensates for it, by upping the fuel mix...
i removed the honeycomb in the MAF area of the intake....useless restriction...like a piece of metal or wood is gonna go through the air filter and make it to the TB....lol
but most MAF's are fairly thick in the support brackets not to mention the sensor itself....jet makes an upgraded MAF for the 1st gens....
much better design...worth money?!? not untill my maf takes a dumb....
and i get what saying about back in the days doing both at the same time, which would eb easier, cause your not gonna want to retune (timing, mixtures, etc) twice....better to do it all at one time...but now days, all thats computer controlled for the most part (timing you can still change on certain engines), so its doesnt matter what order you do things...
