Thanks for posting. That is INSANE. Our race cars were running 128mph in the early 1990's. I came to this site because I was under the impression the next C63 was getting the 5.5L TT. SOOOOOO disappointed about the 4.0 TT.
The W205 C63 & C63pp will get a M177 V8 4.0tt w/turbo's in the V back (ignition coil run hot & should be fixed by now). With race proven cylinder head technology from the M270/133. The M177 PP w/IHI ICSI turbos hopefully will be at the par or better to the Audi 4.0TFSI+ version, and be stronger than a M5/M6 S63tu 4.4l ZCP (Competition Pkg)
On the other had C63 w/M156 there's a few supercharged and twin turbo examples that are proven to be good, but at a sacrifice of MPG consumption. "
Sorry, I should have been more clear. A high temperature drop will always lead to high pressure drop. I realize other factors come into play with pressure drop like end tanks though. I know the Wagner flows a lot more than stock and has a much better end tank design then stock. Additionally it cools a lot better than stock and makes more HP than stock. Knowing four things it would be impossible to come to the results they did unless they set up each test completely different than the others to get the results they wanted. The heat soak test for instance could be with no flow over it and purely based on weight of the metal using a high gear or a load dyno. I think that's too much credit though, likely the numbers are adjusted.
A temperature drop has nothing to do with the pressure drop of an intercooler actually. The pressure drop is a measure of the cores resistance to flow, that's all. It's affected by things like core style, internal surface area, end tanks, general design etc. It's a common misconseption because people think about how cooler air is denser. While this is true, that only counts before the turbo and effects compressor efficiency and core heat exchange efficiency. Think of the air after the turbo in terms of an air mass rather than pressure, and the pressure drop as a decrease in how fast that air mass can make it to your motor. "
" I think the margin of error for hybrids is lower than a moderate tuned big single. Also, I've use Cobb and seen the corrections. Sometimes they occur and its not knock (unless race gas on 12psi can knock...) but honestly with a good setup (fmic, DP's) and decent fuel (E40+ with 93 pump) I have never seen anything with Cobb that looked like knock on any cylinder. So tell me more about why constantly monitoring all cylinders is critical for me, please. "
well peter i worked at mnc performance when your car was there. i tested drove your car and felt the clutch. i can tell you. you don't have a upgraded clutch. i have a stage 3+ & steel flywheel & my pedal is way stiffer then your pedal. when i drove your car.
Hey Alan thanks for the input, did it feel like stock though? It's just weird because last night it is way stiffer than a stock 335 clutch I felt confirmed by me and the owner of that car, and it's also stiffer than my friends M3. Maybe it's not as stiff as a stage 3+ but something in between? "
I have, I believe the m3 is heavier by a bit. That's the reason to believe it is still stock. I would most likely bet you have some sort of clutch disc other than stock. Either ACT puck design which leads me to think that why it grabs harder than usual. HPF has a full disc so I would think it's more like OEM... Anyways my 2cents don't do anything until the clutch dies. If it holds then you're in luck.
Yea no plans on touching it until it goes out I was just wondering if there was somehow a way of doing it. Mine is way heavier than the m3 was which is weird "
" Is there anything new, data wise, coming from these turbos? It seems like the new fuss is about the n55 vtt upgrade, but what about what's already here? I'm supposed to receive my set soon, but there has yet been anything new coming from these. Maybe it's my fault for jumping the gun, but I was hoping, by now, that something new would have came up, especially with the 6x6 billet upgrade. "
I have ordered 2 kits 7 months ago, and am very upset.
Holy balls, it has been awhile hasnt it. I was in contact with Tony and thinking about jumping on these, but I thought the time frame was Aug - Sept and to long for me to wait. So I dropped $4k for RBs including install costs and have been enjoying the shit out of my car for the last 7+ Months.
The update photos look great. I hope these kits get in folks hands soon so we can see some records fall. "
Finally was able to get my car into a shop, that I trust, to diagnose the issue. At first it was thought the Guibo and Center bearing support may have failed due to adding a differential brace that perhaps reflected vibration back down the driveline.
Today, my driveline was dissected, taken apart and diagnosed. the guibo and center bearing support were all healthy, driveshaft had no binding, and the differential was perfectly ok.
So now we are down to the side shafts, wheels, and tires
It kinda hard to believe my rear PSS tires have anything to do with this. I just got them 8 months ago "
