Petro ,
Congrats on your times!! on a different note, I might be the only person to notice or to mention it but don't you think that your trap speed hasn't improve much compare to when you didn't have the headers? I almost swear your previous signature was 11.9@118 or maybe a 12.0 @118.
The reason why I am asking is because I have been following your post on the Renntech when you gained 2mph or so but now with the new tune and long tube headers you gained ET(improved the ET) but slightly improved your traps. Please correct me if I am wrong.

^^ Thanks!! but that is what my original topic was about. 2mph trap speed increase with the long tube headers+cat less midpipes+tune seems to me a little low. In contrast the ET are good. I was only making and observation, actually I am very happy for him regardless.

For the C63, I think this might be true. We've installed a bunch of these headers and built some really fast cars 63's and 55's.. Along with a bunch of other MBZ's. Some guys race. However most of them don't. It is what it is. In fact I haven't even raced in over 6 mouths. Before I started MBH I had a lot more free time. Now its like my day doesn't end until I shut my eyes.
My mind frame has sort of switched of the last year. Dyno numbers and track times are great. It is.. always cool to hear track times from people running our setup. At the end of the day. when a customer call you up or emails you.. To tell you how happy they are. Or how positive the experiences is. Thats what I'm living for these days.
I mean this with all sincerity too. I remember chasing the C55 record and living for a number. The feeling you get when the booth give you your time slip... showing you that you just beat a record. It feel like scoring a touchdown in high school football. Or hitting a homerun in little league. Its such a cool feeling. One you just want to crack a beer open to and celibate.
These days its all about getting that message in your inbox or a phone call from the customer. Or even finding a thread like this. Its exciting to know people are happy with something you put out there.

The dyno #s and track times are ways to measure the objective performance of modifications, but objectively-measured performance deltas are only part of the ownership experience; a lot of subjective feelings come into play as well (sound, fitment, customer service, etc.).
At the end of the day, if the customer is satisfied with the product received at the price paid, there's not much else that matters.

Someone would have to calculate the DA-adjusted times for each run to figure out the "apples-to-apples" difference between the two runs:
11.85 @ 118.37 (DA = -194)
11.58 @ 120.66 (DA = -691)
That would give you the best approximate data you'd find for how much headers/midpipes/retune improved Petro's times. Sort of leveling the playing field as if the modifications were tested back to back, same track same day (which isn't realistic with too many modifications to actually test that way).
The only calculator I found online was at smokemup.com and I don't have a subscription (seems you need one to use their calculators - they're not free).

I fully expect the car to run much stronger. Only have about 200
miles on the new tune which included the trip out there.

That was accomplished only once in very good weather and with good
track prep. Basically, I've only had four sub 12 second runs before the
headers and all my other runs were 12.0's and 12.1's consistently
anywhere between 116 to 118 MPH.
Based on my calculations, I've gained about 4/10th's and 4 MPH on average
with headers and subsequent tune.
I am extremely happy with the results. I have no doubt this car will go
11.4's eventually.

You are correct. I would expect anything in negative DA to correct up in ET and down in trap speeds even if it's minor.

In all my testing from different tracks, using different weather sites, DA predictors and even some experiments with handheld DA units, I've never once had close measurements to what dragtimes states. I find their DA measurement to always be off for some reason. Their corrections were completely off for supercharged/turbo cars but were at least close for NA cars.

Just to clarify a little, my best run before the headers was 11.85 @ 118.37.
That was accomplished only once in very good weather and with good
track prep. Basically, I've only had four sub 12 second runs before the
headers and all my other runs were 12.0's and 12.1's consistently
anywhere between 116 to 118 MPH.

Either way, unless you think the timing equipment was faulty, there's nothing inaccurate with comparing the best pre-header/retune run with the best post-header/retune run - it's especially useful since they were achieved at the same track. Now, if the DA was wildly different, that could lead to inaccurate conclusions; in this case, the DA appears to be in favor of the post-header run results.
I am extremely happy with the results.

Petro - not being argumentative, but I can't calculate those gains? You seem quite efficient and repeatable with your results (speaks well to your driving prowess), as well as forthcoming when sharing that data with the forum. You say you had "very good weather" for your 11.85 run - but it appears that you had even better relative weather for your 11.58 run; significantly so. Maybe the track prep wasn't quite as good... but a 1.75' 60 isn't bad at all; what was your 60' time for your 11.85 run?

That right there is what matters most.

My 60' on the 11.85 run was 1.80. I've run over 118 once and all my other
runs have been consistently 116 to 118. I can't explain the 11.85 run,
it was just a freak night and definately not because of faulty timing
equipment.
If you look at my October 29th runs with the RENNtech air box which
are my last runs prior to the headers/retune the average of those
runs are 11.976 @ 117.485.
And yesterdays runs averaged: 11.62 @ 120.236
I calculated based on averages but I apologize it comes to about
3-1/2th's and a little less than 3 mph.
I fully expect the car to get faster with more runs. Again, the
car only had about 200 miles on it after the retune. I was always
lead to believe that it takes time for the ECU to fully adapt.
I like providing data to help others make informed decisions and
because I enjoy it.

I had 3 more runs with the RENNtech air box prior to the header
install at Englishtown. I know it's a different track but data is data.
