Is supercharging worth it?

[RS04YOB]

I want a supercharger,i just felt the need to say it out loud























I'm skint though

[Jules]

Cheers for the support Philip

Maybe one day

[rs4blacked]

For me having a supercharger fitted would

1. Induce a huge grin on my face from the supercharger whine.
2. Allow quick and safe overtaking manoeuvres where safely possible.
3. make me buy shares in a fuel company.
3. make sure the RS4 is never sold.

Sooooo, nothing about the 1/4 mile then?
Would you consider a 1/4 mile time when making a decision on which kit to buy? Is it important?

Feck NO, I see supercharging as a way to improve the drive-ability of the car, couldn't give a monkeys about the 1/4 mile time.
But I would need to test drive each kit available for a good 24 hours to see which one i could live with and it would
also depend on the supplying dealer how they treated me etc before departing with any cash.

Yes.
And if its quicker than a mapped c6, I'd consider it

[bam_bam]

If it's not one trollfather, it's the other.
...and what did your C6 1/4 @?

[Mr V10]

Golfather/golfather have some connection to each other, I spotted one of the others cars in the background of one of their pics. Their similair names is no coincedence. I met one of them at MRC (Kash)? top guy anyway, think it was Golfather.

1. Absolutely YES!
2. YES again.
3. I did that too!
4. Never say never but not for a VERY long time I think!

BTW, I really don't give a monkeys toss about 1/4 mile times either. I didn't consider it before fitting my charger and I'm still not particularly interested now,- though I am curious to see what Doug does with Dannys car at the weekend!
So to answer the OP's question YES it worth it, though you'd have to be keeping your car for a while to get anything like your moneys worth out of it. 16K is a helluva lot of money to spend on modding the engine on a 20-25k car.

[sakimano]

And what if Doug can't get the car launched, as a result, has a less than stellar ET but an ok 1/4 and trap? Does this become a conclusive measure or does this become another finger pointing exercise for sakimano?
Is it really that important?
If another kit posted a better 1/4 mile time but didn't rate very well in the questions above, then would people flock to it?
A 1/4 mile time just isn't going to factor very heavily in the minds of people buying this mod. Of course I could be wrong and sakimano could be the catalyst for everyone turning their fast Audi's into drag cars, could happen...

At first I thought you were just being malicious and ignorant...but now I think you're just a moron...

1. a quarter mile is a great measurement of how the car is accelerating
2. a quarter mile's MPH still gives us a great indication of how the car is doing even if the driver doesn't squeeze every last inch out of the car, thus objections to potential for 'driver error' etc. are unfounded, especially if we see a video of the run pointing to the driver's aptitude
3. a quarter mile shows how well the tuner is helping the car make power, and how he helps it put the power to the ground via driving dynamics (i.e. if it's strong 'in gear', but flops coming into a new gear, your 1 gear pull is useless)

NOBODY wants to turn these cars into drag cars, just as NOBODY wants to turn them into dyno-only cars (but people dyno them all the time to test them).

We want to measure their performance in a fashion that allows us to evaluate the car in a bunch of gears, at a bunch of speeds, with lots of data along the way, measuring both power and driving dynamics. We also want to compare it to other kits/mods/cars. There are plenty of tests to put a kit through before you buy it, but a quarter mile time is a GREAT way to remove ANY doubt about what it can do (or can unfortunately shine a spotlight on what it CAN'T do, as happened to the PES kits).

Only people like you have trouble with this concept. You just want to complain and bitch and moan because a bunch of people don't agree that letting your Audi on a dragstrip devalues it in your elitist mind. The driving force behind TTS (horsepower) is a dragstrip maniac. He has a 9 second motorcycle and has been excited as hell to get the TTS S5 and RS4 on the strip to show the world how well his kit performs. Why don't you go <beep> complain to him about that? Why not tell him he's a troglodyte who doesn't understand Audis

FOR THE RECORD...dannyRS4's TTS/MRC Supercharged Audi RS4 went to the dragstrip today driven by an MRC employee, and KICKED SOME ASS!

11.71 @ 124.7 MPH

...faster MPH than any B5 S4/RS4 or C5 RS6 on pump gas EVER.

Here's a couple of posts from audirevolution.net where deltaV dropped the news.

http://audirevolution.net/forum/index.p ... 9#msg12049

Rich has gone away for the weekend but the Mrc boys went down to santa pod with a couple cars tonight. I tagged along Late enough to see one run at least. Dougs rs4 never ran as it developed a knackered battery and wouldn't start ended up calling our friends at the aa to come and get her started. Stu from Mrc managed to get 3 runs in Dannys car. The car was stock interior ect and had 3/4 of a tank of fuel in it. He was still struggling with the start. None of us here are really 1/4 mile guys so you will have to excuse the lack of technique. I can't seem to upload the photo of the time slip from my phone tonight so il just post up the details of the best run.

Run 1. Rt=0.8834 6' 1.8658 330' 5.1272. 1/8et 7.7094 mph 95.29. 1000' et 9.9010 1/4 et 11.7131 mph 124.76

If he could Lern to launch it propperly then we are fairly confident there should be a 11.5 or 11.4 in there somewhere. Need to go back and try again after some practice.

GREAT <beep> TIME!!!!!

MPH of 124 is very very strong

60' is decent at 1.86 but leaves a tenth on the table

330' time is frankly not so good...must have been a bad 1-2 shift and or 2-3 shift. For perspective dan@jhm ran with tune/exhaust/clutch 12.29...with an identical 330 foot time. This car should be in the 4seconds at 330'.

Shows how strong the car is the rest of the way...3rd and 4th gear fly. Another metric in dragracing is 1.55x the 1/8th et will often = the 1/4 et. Your 1/8 et is decent...but 1.55 x 7.70 is 11.9...so again it shows your car left a ton on the table (relatively) in the first half. Probably a result of someone driving a customer's car....not wanting to rape it. The 2nd eighth time is indicstive of a car that can get much deeper...although centrifugal superchargers are top-end focused so could be a by product.


Fyi not even the vaunted b5 s4 or rs4 has matched that MPH on pump gas.


Congratulations TTS and MRC!



Once again, great time guys, and THANK YOU for posting up a time. Get your timeslips in the thread, and hopefully some video...

Once again, great time guys, and THANK YOU for posting up a time. Get your timeslips in the thread, and hopefully some video...

Which raises the question who cares? The majority of people laying down money on this kit won't make a decision based on the quarter mile. Another question: so now the car has run a quarter to your liking, does that mean the dyno results were right or wrong? Not that it matters, again. These measurements are subjective.

[sakimano]

lots of people care...maybe not people who own a c5 rs6 and don't understand how to read a timeslip...but that's understandable. This is the sc rs4 thread...not the c5 rs6 suspension thread.

the performance affirms the 480 whp hub dyno reading...I don't quite follow the crank hp,ps readings mrc etc use...but at 600 ps a.k.a. 590 bhpish that's about 480 whp...so again looks right. Look at other 550 to 600 hp 3900 lb cars on a list of 1/4 times...it looks right at home. Quicker than a 525hp r8 5.2 v10 that weighs 250 lbs less. About equal with a ferrari f430...making high 400hp but 750 lbs less weight. Faster than all the amg63 cars except the sls...and basically equal with it.

Was said before...dynos are nice but having a performance benchmark done to affirm the dyno should certainly give the kit a good boost in the eyes of buyers fearing that its another PES lark.

[bam_bam]

So the dyno numbers weren't far off and we can continue trusting MRC in what they said, because this forum was just SO full of disbelievers and nay sayers, wasn't it?
You waged a crusade where no one gave a <beep>, well done. You also, continued to argue with a bored C5 owner that doesn't own a B7, nor a supercharger nor does he know much, if not anything about 1/4 miles, except, maybe that if you put four of them end-to-end, you might end up with a complete mile.

Sakimano: hero and saviour to the future of B7 superchargers, everywhere.

[PetrolDave]

The majority of people laying down money on this kit won't make a decision based on the quarter mile.

And that's the point that sakimano just doesn't get

He cares about the quarter mile times so he thinks we should all care about the quarter mile times, just how often do we have to tell you sakimano:

We don't give a rats ar*e about the quarter mile time.

So please stop going on about it.

[S4Player]

I care and that's not quick enough so I think mrc are off again today. This time they might drive it hard
