AMD's contribution

B6/7 S4/RS4

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?

#51

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

#52

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

#53

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?

#54

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.

Some fun speculating...

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.

#56

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.

#57

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.

#58

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?

#60

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?

#61

If what I am thinking is correct, they aren’t saying that at all. They are saying at redline it will make 1560cfm, but the blower is capable of 2050cfm at peak, so they are only running it at approx 75%.

Perhaps I misunderstand what they are saying, but it doesn’t seem like they are over driving the blower at all.

#62

The stated max is 2050 cubic meter/hour (not cfm) per the email posted above

#63

no he’s not saying that.

He is saying the blower (TVS1900) is capable of 1560 CFM at its peak (the blower has a redline too).

Eaton is saying the blower is capable of about 1200 CFM at its peak.

Nowhere on the compressor map is CFM mentioned. The units are metres cubed per hour. 1 metre cubed per hour = 0.59 cubic feet per minute (CFM). The map shows 2000 m3/hr as the last number on the x-axis. Peak is actually 2050 m3/hr.

#64

Ahh, my mistake, I read that as CFM. You are correct, I am not sure what he is talking about then, it seems that he would be running it well past it’s limits to make 1560.

#65

so please email him over on quattrofail and have him come straighten us out.

he thought I was posting over there as A4TDI or something but that’s not me. He asked me to email him (then deleted that post when he realised it wasn’t me) but I don’t know his email. Are there even pms over there?

Anyway,invite him over here to bring us up to speed.

Or Jason.

Or someone.

#66

QW doesn’t have a PM system, typically you can click on somebody’s username and it will allow you to email them, but it doesn’t look like he has an email listed. To be honest, I doubt they would come here due in part to the reputation each forum has gotten from the other.

Does this forum even have vendors? How do people post about products? Or is it mainly a free forum?

#67

This forum is scary if you’re full of shit or a troll. If you have legit parts that work and want to have a meaningful discussion its a great place.

Ask jfonz and tts.
