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

Yeah K&N drop ins until your intake is ready.

Is your intake ready yet?!?!?!?!?!??!?!?!?

Tommy P · 03-30-2010, 08:26 AM

Hey Tony with your LTH and a eibach pro kit, do you think the headers are going to be dragging every where like on older V8 cars? or are they tucked up in there pretty good??

Tony, we discovered that osiris couldnt control timing months ago and there are a few threads discussing it.

You guys should keep in mind that most if not all the power from those uprev tunes that made power, came from fuel management. What's been happening is that the folks who are already leaned out with bolt on mods are not making any extra power through the tune. On the other hand, the guys with fewer or no bolt ons experience a much bigger gain since you get to lean it out through the tune and make power that way.

You can't control the timing because the car has an automatic override linked to several temperature sensors. You could go nuts with it, but in the end it does whatever it wants to protect itself. It can be tricked physically, I've seen it done. It seems though that some companies haven't had this limitation and have been able to tune timing at will....

I made like 3hp from my uprev tune at a reputable shop who I'm sure would've done wonders with a stock car.

I'm starting to think we could pick up a good amount of power on a stock 370z just by tuning it. Probably almost as much as an intake and exhaust make.

That is a very astute hypothesis, my friend. And I'm thinking you're probably right.

Thank you for chiming in. It is nice to hear someone say they made little to no power with a tune after having bolt on mods. Your testimony makes me stay sane and stop scratching my head.

As far as the tune making power with no mods due to changing the mapping of the A/F, I do not think the gains will be all that spectacular. Also keep in mind that some people buy exhaust systems for sound and aesthetics without caring about performance. On the flip side some buy just for performance. What I am getting at is buying the exhaust is an experience far beyond (JUST) performance.

Thanks, Tony

Very true! Although I would never bolt anything to my car that didn't improve performance. The added "experience" is a big factor when buying an exhaust.

I agree I also would never bolt anything on that did not make power. I sure as hell would not do it if it lost power. However, I get customers now and again that do not care about the performance factor.

To each his own I guess...

A few teaser pics of the first header built for production...

cotizi · 03-30-2010, 09:36 PM

FYI my car was tuned almost stock (just intakes) by the owner of Uprev and picked up 0 HP/TQ.

On another note those headers look awesome. Is there going to be an option for heat wrapping?

I believe he is offering ceramic coating.

sylenze · 03-30-2010, 10:11 PM

I actually think that UpRev can tune more than AFR...considering Stillen is using UpRev for the tune of their supercharger, shouldnt that mean they have figured out a way to manage all the other stuff... unless the tune coming with the stillen supercharger is actually only tuning the AFR....

In previous discussions with him, Tony advised me against heat-wrapping these headers. Just an fyi.

Another reason why it's better to wait a year+ for other's to figure things out unless you are going for the sweet sound and don't mind spending the $$$.

fyi - I'm having my wife's car tuned this week with UpRev (same mods - FI CBE, 18"resonators, HFC's, CF Mufflers, Stillenn GenIII) - the tuner claims he can adjust timing - I will post for comparison to the SpecialtyZ tune that Tony provided. One map will be 100 octane - btw since there is pure race gas in the tank right now.

Would you see any gains from having LTHs in that case? Has anybody else thought about this?

I still don't have a car, just curious/dreaming. I'm that guy - sorry.

I mentioned this in the other FI LTH thread. Most of the 90's and back cars had the cats after the header/down pipe. That may not pass the cold start smog requirments now-a-days but having like a 200 cell cat after the long tubes I would think would cut down the raw fuel smell and get you by a quick visual. I know this would necessitate a revised mid-pipe but keep it mind for later Tony. It might keep cops and Highway Patrol from rolling you not to mention the possible smell at stop lights. Not sure how that would impact the #'s though.
