tell him to just launch from 2900 to 3100 rpm if he is there…danny asked him to go back
car sounds great
he bogged in the video on the launch…hit the rev limiter in 3rd as well as 4th. Not sure if he should be winding each gear so high but with w cfuge it might make sense
I think run 1 and 2 where launching between 3000, 3500 rpm and he was reporting quite allot of wheel spin. run 3 (the one in the video) was launched at around 2000, rpm.
Yes I also noticed that on run 3 he clipped the limiter from 3 to 4th. 4th always hit the limiter as said. We could just use slightly taller gearing or bigger wheels to eek out another 3-4 mph in that gear.
He was trying to short shift at about 7,300-7,500 in the first 3 gears then let it rev out in 4th to get him over the line. But yes this supercharger does make its real gains in the higher rpm range so it likes it higher than some.
Our ideal aim would be something like an 11.4 @ 127-128 or something like that. Rich seems to think its obtainable if everything was perfect. But I dont have a clue. he is the drag racer not me.
11.4 would be awesome. And thanks for embracing the strip, deltav!
lol. few things tickle me lately but this did…

I love the fact that some people had so much faith in us. lol can I presume that this guy is on here or rs246 as well? Im not a member on audizine so cant break the news that we did indeed get into the 11’s ;D
Why was I 300 miles way this w/e? Well done guys, a bit more practice and low 11’s will have to happen. 8) Next time go with an empty tank not a full one :
.
Just gotta get that clutch in this week so I can back it up with the S5.
Sakimano I appreciate your comments. Its quite amazing that you can go 3/10s slower and a higher speed on the 1/8 than the previous run! Like you say there’s a fair bit to come.
Definitely some strong results there guys!! It sounds like you had a great day to run.
@ deltav, interesting comments about the short shifting the 1st 3 gears. Sounds like with some more practice there will be better times to come.
Here’s on here. He’s very well aware of what’s going on so he probably already knows. Although I don’t know him well, he’ll probably be happy to see that you guys broke into the 11s.
mbgt72 is a good guy who has been around the block and just wanted people to temper their enthusiasm until the kit was proven in the real world (rather than the dyno world). He’ll be quick to congratulate you once he notices you went to the strip and trapped 124 mph on pump gas.
Present and accounted for, that was me!!! Been out of town and sick over the weekend, so hadn’t been on the forums much lately. And that CampioniShop guy is full of it! Same guy pimping Supersprint RS4 catback which necks down to stock piping and speaking “on behalf” of Supersprint as a knowledgeable supplier. Turns out he’s a drop shipper from his garage for about any product he can make a profit on and knows next to nothing beyond manufacture claims.
Check out Saki’s post for a good laugh. . .

More on point though.
Hey, seriously congrats, I’m glad to see APR get knocked off the top simply for the fact that they (imo) used a blower smaller than ideal but marketed otherwise, and you all just proved that by a long shot! JHM’s all motor time made their kit just not justifiable as f.i. vs n/a times just wasn’t that different. But the time just set by you all is a completely different story.
As others have said, that trap tells us everything, and I’d bet there’s more to be had as the tuning is still in early phases in MRC’s eyes I’m sure (fine tuning can make a huge difference and will only get better). Saki’s comments about launches as the first 330’ times are spot on as well.
I had been following the A5oc posts very regularly since the early days, and (unfortunately to y’all) just everything about the situation seemed fishy (MRC’s 1/4 times of B5 builds, some of the people pimping the product and their history, and the fact that Crail was the only track anyone would go to after such a long build period, the same excuses always hear ‘clutch can’t hold the power’, and two companies who had never had involvement in the B6/7 platform at all). All that combined with the history of scammers that hit the scene hard beforehand, and the general lack of proper questioning by the community as to the specifics and proof rather than just accepting info as fact (well saki and others asked many of these question on A5oc early on, but then they got banned. . . probably the worst thing for credibility is to ban people who ask too many questions or shed light on other peoples past).
Also, anything else that could help that car out (lw wheels/lw rotors/catless)? Could you refresh us on the mod list when this ran?
It’d be interesting for ya to do a run with no catback as JustinCredible saw some of his fastest traps in that scenario with nitrous. Just thinking that even with an aftermarket exhaust, it may still not be large enough for the amount of air being pumped through there in the upper RPM’s. I know 91gl is looking at building a 3" catback in preparation for his built motor with JHM blower on the S4, which should be putting down some serious power
Excuse my ignorance… why can VF make a kit for the M3 that makes 700 HP… and can’t do something even remotely close for the S4 or RS4?
M3 - 700hp - VF video
http://www.youtube.com/watch?v=1786HyfmYsc&feature=g-vrec&context=G201591eRVAAAAAAAAAA
Well it is VF, and we all know how well they did with Audi’s. VF are claiming anywhere from 620-690hp (note it is not whp) the TTS RS4 is putting down just over 600hp. If this was to be converted to whp the Audi would be down due to drive train loss
Here is a 1/4 run
http://www.youtube.com/watch?v=Evvwzp6FpoQ
The M3 did 11.11@126, the TTS RS4 in comparison is a little behind in ET but only 2mph behind in the trap.
All in all the boys in the UK have done a great job and congrats on the time.
If you look at VF, their “successful” kits have always featured a centrifugal style blower. This is not saying that you cannot make power with a roots/screw type blower, but I think R&D costs, packaging, etc lead to VF choosing a blower that was less than optimal for the Audi’s.
I like that Matt Farah dude
X2. His test drives are almost as good as Top Gear UK’s… minus the awesome accents
VF has a 10 second E90 M3 kit I believe, don’t they?
anyway, they’re apparently working on a new kit for the B6/7 S4. Not sure if it will translate to the RS4. They’re going TVS as well…not sure how far they are along, or whatnot.
Are they really? Do tell! ::insert popcorn eating .gif here::
I would be very very surprised if there m3 kit is making anywhere near a genuine 700bhp. Any of you who visit m3 forums may know a company here in the uk has a rotrex kit in development and as the uk importers for superchargers we have been advising on certain design points ect. In my opinion from the data I have seen then no way is it near 700. It’s still on a vortec v3 but that engine is very sensitive to heat. There numbers a probably dynojet numbers for starters but we have seen that that engine makes around 21-22bhp per pound of boost if you can keep the temps sensible. the chargecooler setups will never match the temps of a good intercooler in those packaging constraints and the rotrex was making a genuine 645bhp @ 9psi with temps of around 12 deg above ambient. With ambient at around 4deg c. for every 1degc heat increase the engine would loose around 1.6-1.8bhp. I would love to see some data logs of boost vs temps for those kits. But if it’s anything like the ess kits then they run the temp sender pre supercharger so you never see Hugh temps. Which seems a little mad to me. The asa supercharger used on the g-power kit is a total monster though ( if used with the correct high boost pulley) although there airbox costs them around 35-40bhp!!! Total bottle neck restriction 
Oh saki forgot to say, yes I think they rana 10.6 but it was on drag slick tyres, and with a paddle shift box. That’s got to be worth a fair bit I should think?
yeah, the VF M3 kit? I think it was drag tires. Big difference for big HP RWD cars when they go with slicks.
That car was otherwise stock and on pump gas I believe. Pretty strong.
VF screwed many folks on our forums over with their Eaton M90 kits (just like PES)…and they will have to work hard to rebuild their reputation.
