Nothing huge to add, but I think headers haven’t been given a fair run yet except Imola’s car, which, to me, has way too much going on with it to be anything representative of the rest of us.
I think Richi’s car is very fucking fast, he just hasn’t gone to the track enough to show it (read this however you like). His first 1/8th was shit, his last 1/8 is solid, he gained FUCKING 27 mph. Show me another car that has come even close to 27 mph on the big 1/8. any car. And he was on fucking 93 octane. Seriously, look at every else’s big 1/8s and the only other one you’ll see is Eurocode at 27 mph.
[quote=“ChrisK,post:26,topic:4177”]
here are the three pulls from that day, every pull just gained more power. not sure what would have happened on a 4th pull
Exactly, people jump to conclusions without looking at all the data or by looking at a single instance at 1 track event. Either wait till you have a big enough pool of data to draw a proper conclusion, or dont talk shit when multiple people post multiple dynos, some quarter mile times, and some side by side pull videos.
he picked up 26.5 MPH, not 27. Normal would be 24-25. Why is 26.5 so groundbreaking that it requires profanity and capital letters?
gaining 26.5 MPH would be impressive if the 1/8th trap speed was 90-91 like most of the B8 guys with those mods. Instead it was 88 MPH, which only 1MPH more than the fastest stock car trapped in the 1/8th. So MPH gained isn’t impressive at all as it points to an artificially low 660 trap.
ironically the day we went to Cayuga in the fall, Mistro’s RS4 with no tune and stock exhaust with slight modifications to it gained over 25 mph, and ran the same time as Richib86. Further, the white E92 M3 that was with us added 26.5 MPH to his 1/8th trap speeds a couple of different times. He was also on pump gas. No FUCKING necessary.
your theory might hold water if it was ‘1 track event’…but it has already been half a dozen track visits.
Eurocode has been a few different times, all with pretty mediocre to terrible results.
Richi has been once, and has done the PBOX a couple of other times. All of his results point to the results the 034 HFC guys get. No more.
Imola Monster went with primetime with APR tune/pulley/LW wheels/seats pulled out and still ran same trap speeds as primetime (within 1 MPH). they both had race gas, both drive DSG and both made no mistakes…while primetime had his seats in.
So this whole ‘1 track visit’ is a bit of a joke. There are about 30 dragstrip passes made by 3 cars over 6 different dragstrip visits with headers.
In other words a $1200 engine pull + $2800 headers = $4,000 for test pipe/034 HFC type performance !!! Who the fuck in their right mind is arguing for headers?
You guys need to try harder to convince everyone that you’re good headers salesmen. So far you’re failing, and I am NOT giving you any Glengarry leads.
I dont sell headers, or any car parts. I sell windows and doors for houses and I’m a great salesman when it comes to that. I’m not trying to sell anyone anything, Im just refuting what people with 0 first hand experience with these headers are saying about them.
You said Richi slow first 660 gave him a fast last 660. That is the stupidest fucking thing I ever read.
Then you compared a bunch of other cars (RS4, M3) to the B8 S4. How is that fucking relevant?
Put your spreadsheet skills to work, and you’ll see that on pump gas (or race gas), nobody is fucking close to Richi’s big end 660. That I even have to say “keep to the B8 S4” is only because someone has to tell you.
Jay, In the office so I can’t post pics but I have a slip where I picked up 27.11mph between the 1/8th trap and 1/4 trap(119.46 - 92.35 = 27.11)… I’ll post when I get home… Curious on your comments about Imola’s car having way to much going on? What do you mean by that?
people who dont have the headers, who dont even have this car are talking and talking and talking out of their asses,about a small sample of cars(yes 3-6 is a small sample) and are choosing to ignore any shred of positive evidence about these headers.
Yeah, I see that slip here Prime. Nice n fast. I took numbers from my comparison last fall in a post here, I think that was before you and 81Bear set your latest fast times.
I’ll do a plot of big end 660s for fun tonight, it’s worth looking into. I’ll check imola’s slips too. With his weight loss program, his car is way different for comparison, but I guess it should only be faster, there’s a point there.
Anyway there’s many ways of looking at it, I’m of the general agreement getting HFCs or test pipes gives you most of the gains of headers, but there’s always an anomoly like Richi’s car that can make you think about it again, especially since he did it on pump.
The real shame is people haven’t made it to the drag strip enough with headers, considering how many sets are on the streets…
J, Understood… Agreed not enough strip times from the header guys which is a shame… I’ll get Imola to come out a few times this year and I’ll pilot his car if he is cool with that… I guess this may give the the “actual experience” paper is looking for… lol
I had forgot if I posted that slip or not as I usually just post a few of them each time I go but looks like I did… lol
My point all along in comparing to Imola is that his car was very close to mine mod wise but in fact had 250ish in weight reduction along with him not having the sport dif which makes it lighter… He also had lighter 18’s but my BBK probably offset the difference there… I didn’t have the LW rears at the time…
I promised someone you know (who’s probably watching here right now ;-)) that I’d do something else on a spreadsheet and I haven’t yet, but right after that I’ll do the 660 plot.
I didn’t want to “say” inexperience, but yeah, maybe that’s what I meant with imola. That would be AWESOME if you guys switched cars, not just to know what you’d do in his, but to see what he’d do in yours…
Maybe you think it’s stupid because you don’t know much about the quarter mile? I mean I know you think you’re a dragstrip superstar because you drove your automatic down the strip a few times and because your big brother had a mustang once…but if you sandbag the first half (intentionally or unintentionally with poor driving) you are set up for a bigger than normal MPH gain on the big end.
If I go and trap 20 MPH in my car at the 1/8th, you don’t think that in the last 660 feet I can get it over 47 MPH? No? That’s because you don’t know what you’re talking about.
Gaining 26 MPH is a lot easier in a car that trapped 88 at the 1/8th than it is in a car that trapped 90 or 91. That’s what happened to richi (as a result of modest launches and shifting, and a slipping clutch…he should be trapping 90 at teh 1/8th and likely 115.5 at the 1/4
Richi said he struggled mightily with traction that day and you yourself said Richi didn’t shift very swiftly. Remember the M3 that was with us in the fall? When he drove well he gained about 25 MPH on the big end. When he struggled mightily with launching and traction in 1st, he picked up 26-27 MPH.

You are a piece of work. Let’s see what you said that prompted me to reference other cars…

So, do you understand now? The fact that it was two cars that did it right under your fucking nose is hilarious. It’s OK…you’re wrong (again). Just eat a shit burger, apologize and move on. Happens to everyone.
Want to see the funniest part? The biggest big end MPH gain ever for a B8 S4 was 81bear who added 27.6 MPH, 1.1 MPH more than richi, right under your fucking nose that same day in the fall.
I realise the little kids on audizine are scared off with your chem eng bravado, but Jspazz, get used to being told you’re wrong or out of line. This is audirevolution.
