swasna the prices for the TTS kit you quote include 20% VAT tax in the Uk, Where as there will be some import duty into the US and shipping, it won’t equate to $3300 ish reduced none VAT price. I would estimate a landed price of around $17500. This is not a stack 'em high sell 'um cheap type product. :slight_smile:

WHat’s the weight of the TVS superchargers, the Rotrex is 6.5 kg or 14.3 Lb. We need to weight the total conversion and subtract the removed parts to see what we are putting over the front wheels. Its something to consider.

I just want to see one legit 12’s slip, he is probably just another 13s RS4…

and I own an S4, should I automatically feel obligated to go by an RS4 just to fit into this post? No, I think I’d rather take my current platform as far as it can go.

I will be very interested in 1/4mile time of this kit, but I’m not even sure why companies are trying to get into the B7 RS4 platform, they should just move on. Their kits will probably be $10k more than JHMs, and slower.

Well as tts showed, there’s a market for a premium priced kit that offers premium performance.

Hell guys were paying 18,000 for the APR kit when it first came out and they sold dozens.

Jhm may cost more than we think…the rs4 kit might need a bunch of things the s4 kit doesn’t.

I.E. While the s4 kit needs no intercooler because the power levels and efficiency zone the blower is working in are a walk in the park for it, on the rs4 with a ‘lightly built’ motor from the factory, it will be doing quite different work.

Its going to be a fun 2012. Great to see 3 options that finally make some sense. I just hope all the low hanging fruit wasn’t eaten up by pes etc, and there’s still a viable market for these 3.

He isnt scouring the internet…

It blew out the window, he had to drive back and check the fields for it ;D

Thanks for the info Saki, I was not aware of the JHM S4 and RS4 SC kits possibly being very different. I would be very excited for all 3 kits to perform well, at least it would give RS4 guys more than one option.

HP thanks for the response. I am assuming this would only get us the SC w/o tuning. I heard that MRC has a good relationship with one of the East Coast US tuners. Do you know if that is EPL? If so, do you think someone could buy your setup and then have EPL do the tune or actually have EPL install the tune?

Thanks again.

agree with you. it would be great to have 3 kits to choose from. hopefully amd/epl can deliver something that does actually perform.

Considering epl is in pretty deep with the AMd kit I doubt they’d want to tune the competitor (nor should a customer want them to due to the conflict of interests).

Why would you want epl to tune one of these kits at all? Have they shown any good results on a 4.2 car ever? I don’t mean dynos either. This is a serious question.

Despite their reputation in the b5 world you know that only one of the top 40 b5 s4 quarter mile times is an EPL tune…and it was tweaked by the owner anyway so it wasn’t really an EPL tune.

Explain that…and please explain why the quattroworld rs4 guys all think EPL is so great. I see nothing but shiny floors and nice dyno results. I saw that from PES and VF too, but that doesn’t mean the results were any good.

Seriously swesna…give me something…and not ‘because mick/manny/etc say so’

saki…there are some rumors that manny may have gotten a tts sc and i am wondering who would tune it over here bc there was mention of amd being in contact with a tuner on the east coast. maybe hp knows about this that is why i am asking him. if someone did get the tts sc over here how would it be tuned?

i am all about seeing real results prior to buying…if i do end up going with epl for my tune…that is a gamble with my money at this point bc i have not seen any real data to support their tune…just butt dyno talk. but at this point i can not jhm if i wanted…but maybe that is coming soon then it will be an option.

i do have jhm intake spacer on a shelf down in my basement waiting. they are made really nice and i have heard they do reduce intake manifold temps.

So no answer on EPL? Nothing?

I’ve got a load of pictures and some cad drawings of the amd kit I’ll look them out. Tony at Epl and mihnea from Mrc are very good mates and I believe they talk almost daily. Mihnea is a very capable tuner with b7 engine so I wouldn’t be surprised if Epl do ask him about tuning

I Would highly doubt He would get involved as that would be a rather large conflict of interests.

I never said he would do it I said I wouldn’t be surprised if they asked him about the tuning darren after all who’s got the knowledge he does with regards to tuning the supercharger kits on the b7? He’s tuned three variations and at the minute is responsible for around what 20 tunes kits around the world. Anyway any updates on my engine?

can someone help me understand this.

Here’s Eaton’s TVSr1900 map.

Where does Jon Cohen see 1560 CFM on there? (speaking about the TVSr1900)

according to what I’ve read, in an overly simplified form for discussion:

1 m3/hr = 0.59 CFM
1 CFM = approximately 0.66 crank hp (before accounting for the losses of actually running the supercharger (25-75 hp depending on the blower)

Is he using the 40% efficiency corner on the map, where it says 2000 m3/hr? Is that even a reliable metric to use for making power?

Anyway even if he is, it says 2000 m3/hr at the extreme corner of the map, which is 1180 CFM which is 778 crank hp before losses.

I still don’t see 1560 CFM. He mentions 1560 CFM for the TVSr1900 but that’s about 40% higher than the map Eaton posted. He mentions ‘at redline’ a.k.a. the supercharger’s redline…a.k.a. the level at which Eaton won’t warranty the part? Is that even relevant?

The Eaton map to me screams 1800 m3/hr where it starts getting stretched = 1062 CFM = 700 hp before losses = 650-675 crank hp = 525 whp at around 20% drivetrain loss on an RS4.

Hopefully someone much smarter than me can chime in and show me what I’m missing.

Per a technical specialist @ Eaton
Max CFM for the 1900 series is 18,000RPM at a max flow rate of 2050 m^3 per hour.

I just asked him a few more questions and am waiting for a response.

Thanks for the response ttsrs4.

I had thought that mrc and epl got along with each other and talked regarding tuning based on what has been posted in the forums.

there you go…so what the heck was jonathen cohen quoting? Hopefully he signs up here and can share some info.

Jason @ AMD signed up too I think.

Heres his actual response including all his contact info.

I really just went on the eaton website and asked them the question

What is the max CFM the 1900 series is capable on to receive the response.

I am wondering if he means that it produces 1560cfm at motor redline the way they have the pulleys setup?

so you think they’re going to rev the blower well past it’s manufacturer stated maximum RPMs? That wouldn’t be so wise would it?
