Went to Dragway 42 in West Salem Ohio. 14.213 was my best time. This car is a bitch to launch! The track was pretty greasy too. There were a few guys saying they run about .5 sec faster at Norwalk dragway. I iced down the intake manifold for my last run which was the fastest. It must have added some power because my mph was 99.53. Here are the details from the slip. My 60' times weren't very good. Happy with the trap speeds though.

Best Run

60ft----2.256
330ft---6.108

^This run was against my buddy in my old Audi. He ran a 14.9 which was his best run with the car. I ran a 14.7 with it on a previous run. He ran a 13.30 with his '01 S4 last week though. Had a great time at the track! I couldn't believe how many compliments I got on the car. Most people were pretty suprised at how quick it was. I was wishing for that elusive 13.9 though but it was a blast!

 

Good times...!

He ran a 13.30 ? What all does he have done.. ?

 

Thanks Jonesi. He has all this except for the manifolds.

He had a valve go which the dealership replaced under warranty. They told him they would put whatever he wanted on it since they had to drop the motor so he got this kit. 440 hp! He has a hard time launching so there is probably a lot better time that can be had. He says he wants me to drive it to see if it will get into the 12s. Quattros will do 1.8 '60 ft times pretty easy if you know how to do it. he was running low 2s on his '60.

 

except for the obvious (acura cl-s)...what do you have?

 

Good times.... drop your 60-foot somehow and you are in the 13's!!
Your mph shows you are making good power!

 

Thanks man. Yeah I'm thinking I'm close. Perhaps a better track. I really want to try spherical bearings to replace the radius rod bushings to see if the wheel hop can be handled. On the last run though I dropped the tire pressure to 26 and it launched a lot better. Actualy felt like I could have launched a bit harder than I did. Might just need some practice.

 

Well I used to have a 1993 Audi S4 that I sold to my friend I was with. He also has an '01 S4. I just have the CL right now.

 

auto or 6 speed??

what mods??

great times

 

Thanks Darrin,

6-speed, CT Headers, Icebox, Mugen T-stat+switch, Grounding kit, TPS mod. Need some traction big time.

 

Traction is the key w/ these cars. Ya know, you mentioned wheel hop. I don't think I've ever gotten wheel hop at the track. It is usually a pretty even wheel spin for me.

 

S4's are so easy to make power with.

my friend's 01 with just a chip ran a 12.9. and made 320hp and 388 tq on a dyno. all stock except chip.

 

Until the turbos go!!



Sweet times ChadT!


My automatic is still faster though!
It's obvious that traction is what is slowing your times down. Stock wheels? tires?

 

What RPM do you launch at? If I go any higher than 2000 rpm I'll hop.

 

I don't torque brake it. With the supercharger I actually like to just launch from idle. Maybe I'm wrong but I think I get more uncontrolled wheel spin when launching at higher RPM's.

 

Hmm... my S/C goes on in about 3 weeks and I can't wait to play with it. Is the torque that much greater down low (off the line) with the S/C?

 

Nice Chad. The infamous 6 MT wheel hop saga. I know when I find the 6MT I want it is going to be learning to launch all over again

 

6mt's you guys should look into weather a kit from energy suspension would fit the supplimentry web type motor mounts you guys have

 

I filled mine motor and trans mounts with urethane already. Makes a big difference in shift quality and how solid the car feels on shifts but didn't cure the wheel hop. I plan on getting a set of these solid bearings to mount the radius rods with instead of the rubber bushings.





I'm thinking that is where the slop causing the hop is coming from. The stock radius rod bushings are big and soft and they are all that locates the lower arm front to back.

 

Thanks Mr Steve. I have SSR Comps with 235/45 Falken Azien ST115s. I was actualy getting the hang of it on the last run. When I dropped the tire pressure in front to 26psi (Hot Yikes!) I got very little hop. I think I could have gotten the tires scrubed a lot better with my burnout and launched quite a bit harder. I'm sure it can be overcome with technique. I think if the wheel hop were eliminated the car would be a dream to launch. It's got lots of grunt and a really low first gear. BTW the 6-speed trans peformed flawlessly at the track. Actually shifts like butter when you are hammering on it. Was a lot of fun to bang through the gears.

 

Launch in 2nd (6K RPMs)... it works!!

 

what kind of times have u gotten with that method???

 

Holy clutch drop batman!

 

I know he went 13.5 NA and 12ish with the first turbo setup. Scalbert also tried this with his S/C setup and said it launched nice and smooth in second. I wonder how the first gear auto and 2nd gear 6-speed ratios compare. What's top speed in first with the Auto?

 

40ish?

 

Well the 6-speed tops out around 60ish in 2nd so that's a bit taller. I've accidentally started in third a couple times and not stalled though. I'll bet it would be quick to start in second. Would help a lot with traction and eliminate a shift. Allmotor knows his stuff. He throws out little tips like this once in a while.

 

You should try it next time you go, or even on the street once or twice.

Although a 6,000 rpm start That can't be healthy for the drivetrain. No?

 

Yeah I'll try doing it gently. Will be harder on the clutch for sure. Should be easier on the axles and such as the touque will be reduced. Probably helps the car hook up for this same reason. Not sure I'm comfortable with the RPMs that will be needed to keep it from bogging. I've done lots of 4-5k launches in Audi Quattros though. Can't be much harder on the clutch than that.

 

thats tight

Thats about what I ran, but I'm on drag radials. Even with the psi dropped down to 18psi I was still hopping if I tried to launch too agressively.

I had thought about trying to launch in 2nd, but to me that sounds too abusive. To get a good launch without bogging in 2nd you'd have to do a very high rpm launch, like 5k+. You cant expect to just drop it at 5k and hook without bogging, especially in 2nd gear. You'd have to really slip the clutch for a couple feet to keep the engine from bogging, and plus 2nd isnt gona be strong until ~30mph.

Good times btw. I plan on going back before the end of the season with some spring blocks to see if I can cut out some of the wheelhop via reducing weight transfer.

 

This approach seems to work best for me as well(1000-1500 range), any thing beyond 1500 rpm is just too much wheel spin.

 

Yeah I'm not sure about the 2nd gear drop deal either. I'm sure it would yeild a good ET if you really reved it but I'm not sure I'm comfortable with doing a 6k second gear drop. Plus when I go to the track I like to see what the car can do the way I drive it every day. I'm probably going to try gettig some of those radius rod bearings to see if that cures the hop. The bad thing about wheel hop is that the stickier tires you use the more you will tend to hop when they break loose. Seems like traction is definitely the key. 14.2 is awesome for bone stock!

 

Mine didnt seem to hop any more or any less than what it does on the stock tires at 35psi. It definitely dod not spun tho, just hopped like a rabbit on crack.

And yeah 2nd gear drop @ 6k may get you a decent 60' and decent ET, but at what cost? The first time I ever drag raced I was in my mustang on worn stock tires. I couldnt hook up in 1st gear for the life of me because I was a noob and the track was ice cold. I actually launched in2nd gear with decent success. However I was going from like 3k rpm and it would not bog or spin. The CL-S doesnt have enough ta to overcome that amount of gearing off the line without some serious clutch slippage.

And 14.2 is pretty decent I guess. I'm shooting for somewhere closer to 14.0 before the end of the season, still bone stock engine.
