I have no doubt the headers work and you will all love them! I want to get a Little more in depth in the tune next time because I feel like there is room for improvement. I can tell you this though, I am throughly convinced that the aftermarket long tube CAI's hurt the torque and power throughout the entire curve. Regardless of what anyones says. At this point I have dynoed enough different 370's with the same outcome.

Thanks, Tony

I believe you 100% , your customers satisfaction is outstanding, and your loyal fan base is really unmatched from anything I have seen on forums.

You seem to do research on a level that many other people/companies do not do, and I am not trying to dis-credit anything you are saying...

Its really going to take a few people who have money to burn to go the extra distance to have a 370z with full bolt-ons. Tune the car. Than Swap stock box back, tune the car again, than dyno again. And share the outcome with others.

And other people also need to follow the first person to do this , and once 2,3,4 people see similar results than people will start to believe it, whatever the conclusion ends up being.

I would not be all that surprised if it was true but its hard to discredit the dynos that show big gains on otherwise STOCK cars, but who knows once you open up the exhaust..

Id love for someone to go dyno happy once they get these LTHs... my one concern is though if you are tuned with a CAI, and you swap your stock box box and dyno , it really wont be right.. You would have to re-tune as tony has shown his A/F does stay pretty darn close to stock with just his exhaust mods. And the CAI def throws it off.. You would need a dyno, swap of intakes, re-tune, dyno.. Or a stock tuned car to do it, but with the ecu learning theory that may be discredited too.

Long live the CAI vs OEM air box debate!

Also I have had ZERO problems with my stillen intakes.. I did not do before and after so I can not comment on power made but IMO they helped and had no install issues.. The exhaust def did present some fitments issues to me, which were addressed by heating the mid pipe and raising it up, which is nonsense IMO, BUT IMO stillen does not put out terrible products but they are far from perfect.. I purchased my exhaust used otherwise I would most likely of went the FI route but I did the budget route on the exhaust to save some money for the LTH ...

Stillen products have shown to make gains on customers dynos and that is what convinced me to get their products for this car.. The Stillen headers however showed little to no gain and I was very happy to see FI coming out with these LTHs.

Not trying to start crap It just seems as if this thread is filled with optimism, I'm sorry for throwing a little of my pessimistic ways into this thread.

so what you are saying tony is

keep stock airbox?

chuckd05 · 03-29-2010, 10:45 PM

Another question off topic...

Do you know if the car made any more power with 100 octane ?

I have experimented with some from a local gas station by my house and other than the sweet smell I couldn't tell if it helped the car or not...

The car had a half of tank of 91 crap California gas. Then we dumped in 5 gallons of 100! Now in theory the car should take the extra timing you throw at it and hence pick up torque and power. We only did two runs and saw no change. However, my customer drove back to Vegas that evening which is about 300 miles. He told me the following day, he noticed a huge difference once he put some much needed miles on the car.

Back to the air intake issue. As of right now I am starting to feel like this car in it's current N/A stock form may be at it's limit as far as how much air it can take in. There is something going on with these heads and cams and this VVEL thing. Obviously if you change the cams, and port the ever living piss out of the heads you will pick up across the board. But until that happens you can only do so much with the bolt ons.

If I owned a 370Z right now, I would do:

-K&N drops ins
-Possibly an underdrive pulley
-FI LTH's (Of course)

-FI CBE W/18" Resonators & CF mufflers (Of course)

-Sway Bars
-Eibach Pro Kit
-4:10 rear end gears
-UpRev tune

This is just me speaking hypothetically!

Thanks, Tony

Have you been sneaking a peek into my mod list Tony?

vipor · 03-30-2010, 08:22 AM

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??

RCZ · 03-30-2010, 03:56 PM

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.

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 $$$.

Wow, it'd really screw up your plans if those of us who actually adopt and test new parts made a policy of only sharing our results with others who contribute to the community's body of knowledge, wouldn't it? It wouldn't be too hard to do either, seeing as how we can create private groups on this forum. (I'm just making an observation, btw. Pls don't take this remark as an implied threat or anything like that.)

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.
