Thanks for sharing, Arin. Is that Schwarzenegger narrating the vid? lol
I think they’re holding back for now. Part of Arin’s post above:
[quote]Many more acceleration tests were performed, including record setting quarter mile passes, proving an APR Stage III+ TVS1740 Supercharger System is the ultimate upgrade for R8!
[/quote]
The product page on their website likewise lists 1/4 mile results as “N/A”
Nice!
Looking forward to 1/4 mile results too!
Will this fit my A4 ???
arin this is great. The kit looks very well made and put together. I think this is the cheapest R8 kit too…
The times were still record setting for the 4.2L R8 as far as I know, but there’s way too much head room left for me to advertise those results.
Thanks. That would be surprising. It wasn’t cheap on our end to say the least and the laundry list of included parts is quite lengthy.
Wow great price. Cheap for a “supercar” modification.
Details on that intercooler pump? It just looks weird. Is that an OEM pump used in some other application? .
Cross section of the intercoolers?
Yeah, you don’t want to show till you have something special.
As for fastest 4.2 it would likely be the turbo guys in Europe. MRC I believe and someone else who I can’t remember. They were running in the 11s @ 130 MPH.
The 80% rear bias certainly makes it a bit tougher for the R8 than maybe the other Audis.
Can’t really give out any deails on the MFG at the moment. It’s pretty bad ass though. : )
I’ll shoot one later. I have a cut away I would like to photograph.
Yeah, those should be fast. Built motor? IIRC they said some ridiculous numbers.
I’ve seen stock, bolt ons, and VF TVS1900 times. Nothing from PES worth mentioning or any of the single or twin turbo kits, nothing from any of the rotrex kits, or other centrifugal kits. If you know them, post up the results.
Don’t know what MRC did to the motor. Their ET was suffering like yours.
Single turbo. 11.70 @ 128. 6

was this tested on 6spd or r-tronic? How will it work with a 2014+ model using the new s-tronic?
This one’s fast but I can’t read the tinr/mph

11.7? Got that licked, but that 135 though… may need lots of race fuel. ; )
I know this is an old post. But did we ever get results for the kit.
I did notice that once again the turbo kits don’t outperform the well made supercharger kits.
what kind of results? Check the supercharger argument thread.
I know a guy running this kit on his 2008(?) 6MT. He’s gone to the strip before with it. I don’t remember what times he was getting.
But he’s been tracking the car now, I believe has done 3 track days with it at Grattan and is going to mid-ohio with me in a couple weeks. No issues from what I’ve heard. Rode with him and he hammered it pretty good. Hard to tell how fast a car is when sitting in the passenger seat lol
Here it was the night before the Grattan event

Glad to hear no issues so far. how many miles did he have on the car before install and how many since install (if you happen to know). Just curious.
Wish I knew, sorry…he got it on sometime in the fall and then put the car down for the winter. So probably not a lot of miles on the blower, maybe something like 5k miles max? Car is definitely a toy to him.
Have one of these local me as well, pretty damn quick, but like drob23 I was a passenger, so kind of hard to tell, I was intrigued to find out its only running around 7psi compared to almost 16psi on the RS kit?
Also no issues on his, but he’s only had it for about 3-4 weeks now.
Really? why such low psi? Im assuming he isnt making NEAR the claimed HP then? I wonder if they have him dialed back from the piston ring issue ive heard about.
frankly I think all customer cars were dialed back CONSIDERABLY from what APR advertised.
APR advertised 500 whp and 125 mph trap speeds on pump gas at 500 feet of DA.
A customer with 1/4 mile experience and good driving skills, including ALL modifications required to make power (clutch, LW rotating parts, full 2.75" catless exhaust) ran his car and also trapped 125 mph…however he did so in -2800 feet od DA. The delta between the two cars ()APR test car and the customer car) would amount to about 40-50 hp, or about 4-5 MPH of trap speeds. IF the customer had run in +500 feet of DA he would be lucky to trap 121-122 MPH. Something you’d run with 450 whp or so.
Another customer dyno’d his car at an independant dyno and made only 450 whp, but on race gas. This was after 034 motorsports installed a new engine for him, as the APR kit blew his original engine within a couple of weeks of installation.
All in all, the message appears to have gotten through to APR and AMD and they appear to be dialing the kits back (AMD are also selling a kit that is a shell of what they advertised, with customers dynoing 425 whp and running high 11s @ 120-121 mph instead of 500 whp and running low 11s @ 125-126 mph like AMD advertised on the initial AMD customer test car)
Funny thing is the first company to buy an RS4 and supercharge it (JHM ) for 20,000+ testing miles is the only one not to release a big power kit yet to the public. That same company knew 3 years ago what 500 whp and high boost does to an RS4 engine (they showed me when I visited them in 2013). Unfortunately they couldn’t share their R&D especially after APR and AMD rushed their kits to market and posted great 1/4 mile times at what we now know are dangerous power levels. It would just look like JHM was having sour grapes to piss on the accomplishments of their competitors. So JHM has continued with their low boost kit and their built motor program, while being criticized by morons for not being quick enough to market a kit that kills the engine. The fucking irony.
