4400+ lb race weight + 1.4 60 foots =

[TulsaMike4]

Time to order an axle :) I guess being this fast and full weight has its downsides unfortunately!

[angrycatmeow]

I'm honestly surprised I don't see more of these. They can take a beating but I guess shaving 3 seconds off the stock quarter time is where they draw the line.

I think it was a cursed day... we had a solid DA for a change, I made some 10.5 passes before we entered some elimination runs, and this one I finally turned it up. Car hooked great and then BOOM. It could have been a lot of factors though. I swear every 20 minutes another car lined the track with oil, so they were out there all day cleaning up and dragging the box to make it sticky again. One of the tires could have hooked more than the other, or maybe I shouldn't have had two breakfast sandwiches on the way to the track :)

Prior to that, one of the mid 10 second S6s snapped an axle, a coyote mustang snapped an axle, a hellcat blew up and sprayed oil and engine parts all over the track (or transmission, either way it wasn't a good day), and a ton of 9-10 second Hondas were out there with 50% exploding at some point. My day went a lot better than this guys... Someone was picking up large metal chunks before I snapped this photo.

Sounds like you got off easy Must've been good track prep too.

Im very consistent high 1.4 to low 1.5s when im out there, but some of the street tire guys were complaining. It was 30 degrees out most of the day, so that didn't help, but IEs launch control is just beastly, and their slicks only launch is brutal with the Hoosier DR2s. It looks like Audi has the axle in stock, so if I can get it in before next weekend, I may run and pull some weight out since its likely the end of the season for us anyway. I was hoping to get a 10.1 or faster before taking more weight out, but I will have to settle for a 10.2 full weight, and whatever I can get with seats out, possibly a light weigh driver seat if I can find one to borrow.

Elevation isn't too high there so with those temps DA must've been nice. I've always worried about snapping an axle on launch but seeing they can take your times for the most part puts me at ease since my goal is only 11.9

Good luck cracking that 10

Happened to quite a few people now but mostly SQ5’s. Have you weighed your car? Can’t see it being 4400lbs with you in it unless you’re taking the entire family out for a day trip down the 1/4mi lol.

I meant to say 4300, but it only corrected it once you’re in the thread. My car was 4026 without me, I’m 245, and had about 30 lbs of gear in the car.

[TJay74]

Dang that sucks Mike, I saw Austin posting up about his success up there at the event. Hopefully the repair isnt too bad to get it back on the road. I am surprised at the weight though, Audi claims a curb weight of 3850 for the B9 S4.

We all weighed ours, I think Austin was 3950, one of the other B9 cars was similar, a B8 was over 4K, then mine. I also have a 4 gallon methanol tank that was full, plus the meth system, full tank of fuel, larger intercooler, metal charge pipes etc. It all adds up, and I haven't done any weight reduction.

Ah yeah, forgot about the meth kit you’re running. That adds a silly amount of weight.

[TJay74]

I need to go weigh mine soon. I am interested where it would be with my lighter wheels and lighter rotors.

[flee]

Well now I can assume mine is 14lbs lighter than yours, since my meth tank is 2g not 4. , But then again i'm tipping 220.

While many of my mods may not add a ton of weight, collectively they all add up. The ECS exhaust is definitely heavier than stock (factory exhaust is extremely light weight, did the opposite of my plans sadly). I don’t know if anyone has done comparison testing on intercoolers, but the Wagner was quite heavy! I also did the Wagner charge pipes, ECS post throttle body charge pipes, dual nozzle meth kit with stainless lines, the largest pro meth pump, 4 gallon tank that I keep full, the nice stainless full size meth filter, sound deadening on the rear deck, and I usually have my dewalt fan and air compressor in the trunk when I run (they will grow legs very quickly otherwise), as well as laptop bag and laptop, go pro and mounts, then the 10-15 lbs of crap I carry with me at all times 😂 from what I saw with the other s4 cars that weighed all together, the b9 cars with fuel and mods average 3950 lbs or so (stage 2 cars, one had resonators and such deleted)), so mine being another 75 with the above listed stuff sounds about right. If I could find a loaner light weight seat, I’d try a pull with no seats other than the driver, but I really don’t want to get into removing exhaust, panels, and other things beyond seats.

I had considered going back to stock exhaust since gains were minimal, but I’ve come to love the sound of it, and really enjoy being able to hear it in my videos over the wind noise 😂

[A12rnx]

Bro. Just put it on a scale and take a picture

. Yes the meth tank and pump weigh more than a stock car would have but have you put it where the spare wheel used to be? As that will more than likely cancel that weight out. You also run Dr2 and lightweight wheels again less weight than a stock car or your 20s. In order for you to run the times your are at 4300lbs your car would be pushing near 800bhp

You mean like I posted in other threads, bro? It weighs what it weighs, and it runs what it runs.


This is without me in it, and the usual stuff I have in the car was in a buddies Audi since he wasn’t running. This is the absolute lightest my car gets. Before you start talking out your ass with other nonsense, the scale was zero’d before I put the car on there, and it reads just fine for other peoples cars as well.

800 bhp? Very likely, possibly more.

Weigh it as you run it with all the stuff in it. It’s all good guessing this and that but if you did run a record run for full weight where is the proof everyone jumps down IE and 034 throats for not disclosing what they took out. Take a leaf out of Adam Blenders book.

[AldermanToffee]

For what it’s worth, an RS4 that has been dyno’d at 800bhp on a full frame setup is running quicker than you, heavier, full-weight.

I know dyno numbers aren’t all that, but should give you a point of reference.

He ran on an engine dyno to achieve 800 bhp? Or you just fabricated that number? I couldn’t care less what my car makes, or what it runs, but it’s funny to watch everyone get their panties in a bunch over everything.

Well, Bro, I really don’t care what it weighs. What does matter is the only weight reduction done is the spare tire. Anything else is added weight. I don’t expect you to comprehend common sense, nor understand what questions are specifically asked in the drag race thread, but saying “fastest full weight” means everyone ahead of me has substantial weight reduction, and outside of removed spare, which I mentioned, I have none. If you want to go a step further, which again requires common sense and basic math skills, you can use the image I posted, showing the absolute lightest weight my car is capable of weighing at the track, and conclude that regardless of what weight I add, what components I have in the car, and what I weigh, that my car is still the heaviest.
You’ve set the bar low, but I have faith you can figure this out.

[A12rnx]

You do care because you mention it every opportunity. You literally made a thread that we are in saying the weight. 🤡🤡🤡🤡🤡🤡🤡

Stop getting your knickers in a twist lol, I’ve said many times that the numbers you’re putting down on the track / dragy are good. I’m just trying to provide point of references for you seeing as though you think it’s making 800bhp (hint: it isn’t, ask IE themselves).

He ran that number on a MAHA dyno.

I have the dyno numbers from the IE car with my same setup and turbo. I’m running more boost and methanol, but since I don’t like to do theoretical numbers, I haven’t bothered making claims. You generalized that to run what I am, at 4300 lbs, I’d have to make around 800 bhp. I agreed with you, it’s likely in that area. If an RS4 beat me making 800 bhp, good for that vehicle. Anyone on here also knows we’re reaching far past the efficiency range on these s4 engines at the power levels were making, so I wouldn’t expect I have near the top end of a car with twins and much better efficiency. One day one of these s4s doing ported heads and full frame turbos will run a number that shows otherwise, but so far, none have beat any of the guys running hybrids in the 1/4 mile.

The big difference between myself, and others making up titles, power claims etc, is I just don’t care how fast I am, how much power I make, or who I beat. My car is what it is because I was bored and put parts on it that other people hadn’t tried, or that I thought would make it run better.

See this is where making assumptions would show you are wrong. His car is probably making near 800hp at the crank. Based on his ET and his MPH and the car weighing 4400lbs he is making somewhere near 790-820 HP at the crank. Long before there was a dyno of some sort (Engine or chassis) to validate claims there was math that can figure the equation out.

Seems OP is making what he claims, his ET and MPH are all backing that info up. Try not to get so salty next time....

To be fair, it’s 4300, 4400 was a typo. If I get my axle in this week, Saturday I will weigh the car with me in it and someone else snapping the photo. Then this argument, that shouldn’t even be an argument, will be solved.

Of course, except a heavier car running faster times has dyno’d at 800bhp and that was probably a stretch too being it was on pump fuel.

As the user above said, time slips are all that matters and Tulsa is putting down some good times.

[TulsaMike4]

Time slips are the only thing that matters....just my opinion.....

I’m with you on that. It’s the only consistent metric where we don’t have correction factors, variances in results, etc. While some are at a disadvantage, a 1/4 mile is a 1/4 mile.

Yeah I agree your are running awesome times. It’s just hard to believe the weight thing that is all. I appreciate you taking the time and effort and planning to put it to the scales to end it.

I don’t mind taking requests for information, and I think most will agree that A - I’m an open book on what mods I did, how I did them, and what they accomplished (I do not lie, nor bend truth for companies or products), and B, I don’t tend to speculate or give dishonest results from performance tests such as excuses for lower than desired results, losing a race or mechanical issues. Simply asking me will get you just about anything you want, but calling me out or calling me dishonest elicits a completely different response. Had there been someone else to snap the photo for me, I’d have a “race weight” picture, but that’s on the list for Saturday if I make it.

Good lord you are at it again - This is the same guy that swore that my old stock turbo record wasn't at full weight, cried because it was on spongebobs sea strip and swore it was not a release file but a custom EPL map that nobody else had access to....

Always trying to pick apart others shit because you can't do the same

[A12rnx]

Haha I did wonder how long until you came along. Didn’t get very far with your hybrid car though did you? But atleast this guy actually will do some pictures and videos to prove it not that he has but come across as a decent guy. You’re just a top notch knob head who loves his own ego.

[Monty23]

1) As I see it, the point of this thread is to showcase a broken rear axle. This is helpful info to document as this platform is getting more powerful and weaknesses will need to be fixed.

2) Dynos are good tuning tools, but there are so many factors that can make them useless in comparing one car to the next.

3) OP, keep it up. It's good to see people actually using their cars rather than keeping them caged in the garage in fear of breaking something.

[TulsaMike4]

Took the axle out last night since the new one will be here Friday… pretty wicked looking!

[AldermanToffee]

Reasonably priced.. I think a few might be needed some soon: https://driveshaftshop.com/custom-applications/

We will see. Racing season will be over due to weather likely this weekend or next, and I’ve been considering selling this car for an SUV or truck anyway. If I still have it next year when the season starts again, and I break another axle, I might swap them for something more durable, although with my experience, power just finds the next weakness in the chain, which may be a lot more expensive to fix.

[TulsaMike4]

And she’s back on the street! After helping with a buddies S6 axle, I was dreading this a bit, but it’s a 30-45 min job with aftermarket exhaust. I removed the two mid section pipes to my ECS exhaust, removed the plastic diffuser trim to the lower control arm, then the axle just pops right in!

[TulsaMike4]

Track closed due to weather, maybe next weekend.
