Fast Intentions exhaust and header comparison. Before and after UPRev tune (Dyno)

kekermahoney · 03-25-2010, 11:36 PM

wow, potential CAI from FI... think im putting off the G3 puchase just a bit longer.... Hope they are similar in length, since shorties dont seem to put up good numbers (hint hint Tony) lol

Tony knows cars and he's going to build the best intake for the Nissan 370z to date. As of now, aftermarket CAI's only lead to some power past 7000 RPMs. The stock intakes are good enough for now. When Tony comes out with his Fast Intentions intake, I know and trust that it will be better than the stock intake and produce worth while gains! We just have to wait till then...

I really originally wanted to get a tune, but if I'm not seeing much of a gain at the risk of losing my warranty, I kind of need some convincing.

Because regardless of what kind of gains you might get from a tune (or lack thereof), a tune will correct your AFR, which will most likely be out of whack after you make a substantial number of mods to your intake and exhaust. Specifically, we've seen the AFR go lean, which means too much air, not enough fuel. That can cause damage to your engine. In extreme cases, it can even make your engine do a grenade impression.

You could. I was just assuming you'd want to retain the ability to bolt on to any CBE.

You will not void your warranty. You will have the control (yourself) to flash the ECU back to stock if you ever need to go in to the dealer.

Tony I have a feeling with 93 octane I could see better gains after the tune?

Maybe, I hope to put this theory to the test with positive results hopefully.

G37Sam · 03-26-2010, 10:23 AM

I mean I know Nissan did a great job with the OEM headers, but I'm sure Tony did a much better one, those numbers don't do it justice IMO

XwChriswX · 03-26-2010, 10:26 AM

Is there a MASSIVE difference between these two setups?

Stillen Headers --> FI Resonated Test Pipes --> FI CBE

FI LTH's --> FI CBE

Just wondering where the primary difference between a short tube/long tube header lies... Can you explain this to boost my knowlege on headers?

theDreamer · 03-26-2010, 10:42 AM

Sam, is your fuel over there (93 octane) really good, meaning no additives like they do in the US (that 10% sh*t stuff)?

I would think they would have the best gas there in Dubai...

I mean the wells are right up the street arent they in Saudi?

Yeah but where are the refineries? All the crude in the world won't do you much good unless you have a refinery.
