On the drive home I was really able to feel the difference. The car pulls harder and doesn't have that split second lag at around 4k rpm. After driving the car for about 400 miles I can now say I am satisfied with the results.

Sebastian at Specialty Z did a great job on the tune. He spent well over four hours making sure everything was perfect. All things considered I had a great time, learned a lot, and made my car a bit faster. Good times.
Not trying to rain on the parade here, but I have to say that I find the absence of any comment on the impact of these headers on low-end torque and power somewhat conspicuous. What happened on the low end? Please tell me that the gains in the midrange didn't come at a huge expense on the low end. *keeping fingers crossed*

Let's wait on the Dyno graphs before jumping into conclusions too quick

I'm not concluding anything. I'm just asking the question.

On the contrary, we actually picked up torque and power throughout! At the highest gap for a torque increase it was at 4300 RPM's. We had an increase of 18 FT LBS. A far as power, the highest gap increase was at 4300 as well as 5900 RPM's. That increase was around 15-16 RWH. This is just a tid bit, I promise I will post the dynos soon. As far as the tune, what we were mainly able to do is clean the A/F up which made the car safe. The timing we demanded was kicked back by the ECU and I feel higher octane fuel than our California 91 garbage will help the car perform better!

These numbers are all stock cats vs the LTH's right? what do you expect for gains for people that have test pipes..

So, I guess that confirms that timing advance via "tune" still isn't possible - just fuel maps?

Given VVEL, and how it works, it makes sense that they'd not want anyone tweaking timing, you get a valve too far out there where it shouldn't be, and it'll get bent....

I think he meant that the timing adjustments they wanted would have stayed if the fuel wasn't trash. If that's true, thats good news for people with access to 93 octane.

Outstanding. Thx for the reassurance, Tony.

Higher octane would certainly help, but Tony's experience is consistent with mine. The timing adjustments we made went nowhere, and I put Shell 93 in my car.

LiquidZ 03-24-2010 02:11 PM
Semtex, thanks for the clarification.

No, these numbers are over our high flow cats and CBE!

Who is supposed to be posting this dyno chart ? If it's Kolya he is getting a -rep for taking so long. If it's Tony he is getting a neutral rep but it's only cause he's busy as FUUUUUUUUUUUUUUUUUUUU

That's pretty good since it's put up against the HFC..I should have got in on that group buy pricing. Poo.

PS: THE ONLY problem I would have with this setup is still the yearly state inspection I have to go through (next is due 04/11) and I would have to take the LTH off (pay to have someone take them off) and put the stock setup back on. Kinda annoying for me to deal with.

You can always stop by and drool over my set. :tup:

Thanks bro! I will post this dyno chart and the A/F chart in the front of this thread as well. This is just for now to feed you all something...

Thanks, Tony

Nice!

NYBladeZ 03-24-2010 06:31 PM
I was hoping for a bit more power up top, but significant gains through the powerband is even better. One clarification, the pre LTH setup has still headers and F.I. HFC's right? The chart doesn't mention aftermarket headers.

On the last car we made more top end power. The only difference is that it did not have any intakes on it at all. I am just saying...

On your other question, correct in the first dyno session there were stock manifolds on the car. NO headers!

NYBladeZ 03-24-2010 06:35 PM
I gotcha, so the intakes help a bit with the top end power, from what everyone is saying that's the only place they help 7000 or above. Looking forward to more dynographs...

Yes & no.
I do not want to derail the thread, but it seems intake (even with a minor tune) are not playing a big roll. A lot of factors though, better fuel (93 octane), unlock VVEL, intake A or B. Intakes by themselves are good performance numbers, but paired with other items they seemed to not help, currently. Hopefully down the road we will see some improvements, but maybe not.

Love the results Tony, hope things are going well and you can finish up and start full production soon.

Hopefully by the end of today we will have the driver side completely indexed and ready to go. It has taken 3 full days of work just to get the bend perfect. On to the passenger side as soon as we are done. With any luck, I will have some sets in the mail by the end of next week. I will also post pictures of the production headers as soon as they are ready.

In addition I will be adding everything pertaining to these to our website.

Good luck with the new job, hope you can get them soon and enjoy them.
Maybe by then we can find a nice loophole for you with the state inspection.

Driver side is harder! EZ Money from here on out! :excited: :excited: :excited:

NYBladeZ 03-24-2010 10:34 PM
Can't wait, keep the info coming Tony. I'm going to hold of on intakes, I just can justify it, especially since I hope on going S/C down the line. I'm going to match the LTH's up with stock exhaust, in case anyone wants to hear what it sounds like, hopefully I'll pick up a CBE soon after, especially if Tony offers me an awesome deal.

Thanks, Tony
Why didn't anyone get excited about this?

Tony, let me go ahead and put a deposit on your intakes! lol

I will be #1 on the FI Intake buy list for sure!

:happydance:

Vegitto-kun 03-25-2010 05:30 AM
This might be a useless post but how is the 0-60 time with the headers haha

vipor 03-25-2010 08:19 AM
maybe 0.2 seconds faster. maybe.

Show me some sweet intakes to dissuade me from getting G3's. Don't be like AEM and eff up my sprayer bottle either. Gogogo
