wow…so PES went from offering the smallest and most illfitted supercharger to the largest.
Goodbye M90, hello 2.3 litre Whipple
Quite a development. 1430 CFM capable…!
After digging around I found a few 2.3 L whipple mustangs in the 9s and a boatload in the 10s. Really interesting to see how this works out and if PES can manage to not fuck it up lol.
[quote=PES sales rep]Also just annouced in the RS5 section I’m pleased to confirm that PES are in the process of upgrading all their 4.2FSI supercharger kits to fit a 2.3l Whipple twin screw (model:140AX). These blower are a serious upgrade on any of the Eatons, see the Whipple Superchargers website, especially the comparison chart at the bottom of the link for further information.
Development is already well under way on the first R8 fitment and next on schedule is the S5.
correct me if I am wrong as I dont know much about the various blowers, but it was widely discussed that the twin screw blower is the best fit for this car correct? And if so how much more power could we see from this kit? It seems like TTS and JHM have been able to get solid numbers out of their kits thus far
I don’t know what to say. They’re showing 138F (59C) intake temps on a super hot day after a 1-3 WOT pull.
For me, after a 1/4 mile run, say I start at 113F (45C), by the end of the run, I’m at 167F (75C) and that’s on a cold day. On a hot summer day in bumper to bumper traffic, I easily go up to 195F (90C) intake temps, which (thankfully due to the awesome tune) reduces my car to near stock performance levels. I’m glad the tune does this so that my engine remains safe but it makes me think I would beiiinefficientficientficientit from some cooling system for the summer months.
In the winter, my intake temps can also go up quite high if I sit too long in bumper to bumper traffic BUT, when I start moving again, the temps drop pretty quickly due to the cold air. On the highway, I’m easily down to 95F (35C).
In conclusion, I do wish even the stage 1 setups had an intercooler or some sort of more efficient cooling system. I’m no mechanic or engineer so I may not know wtf I’m talking about. I’m simply describing my personal observations.
I’m also assuming that all supercharger applications have the same heat problem. Heck, it’s probably a problem with stock setups as well.
I have in the normal ranges and it’s very accurate. What I haven’t done (and will attempt) is check at the extreme ranges. When I see it above 80C, I’ll check with VAGCOM and see if it goes that high as well. Good point.
That said, on a hot summer day with my intake temps hovering in the high 70s C (170-175F), I ran a 13.7. Shows the effects of the tune’s safety protocols (which is a good thing). Just wish there was a way to keep intake temps down on hot days (within reason obviously).
That 13.7 could also show the effects of it being your fast pass ever at the dragstrip too…(in this configuration - supercharged).
Don’t also forget that with no tune and full exhaust you were running 14.X @ 99 times November 2011.
the day you went 12.6 @ 113 you had a few passes that were quite a bit slower. There’s lots of variance in your pass times and they keep getting better as your comfort level with the car gets better.
If we take your best all motor non-tuned, full exhaust time of 14.0-14.1@99 or whatever in good conditions and compare it to other bone stock avants that went 13.8@101-102 (bangoman, and the other guy in Jersey with the sprint blue B6) you were a couple of tenths and mph slower
In November 2012 your car is 14 tenths faster and 14 MPH faster. That’s a massive change, and I think we would both agree that there’s STILL more in it because you were getting faster on almost every pass before your hose came loose right after the 12.6 @ 113
They will likely make that available to stage 1 people.
The built motor program is humming along and intercooling is going to be part of that so it will be interesting. No idea on cost.
This will be relevant to this thread very shortly as JHM progresses with the supercharger. Dan mentioned recently that they’re tearing down the motor on his car and sending the internals out for strength testing. Novel concept…finding out how strong the motor is by actually testing it on your own car, rather than strapping a kit to a customer’s car and hoping for the best lol.
they’re tearing the whole thing apart actually, so absolutely looking at the heads. I am reasonably sure the RS4 heads already flow really well…I think it’s outlined as one of the key differences between the high revving and low revving 4.2 FSI motors.
Why is it relevant to your interests? Planning to force some air into your motor?
[quote=“sakimano,post:313,topic:3116”]
Not really looking for more flow per-say; smooth runners would be nice from a maintenance point of view, IIRC, there was some room to port-match the exhaust ports as well. Ideally it would be nice to have a better valve seal solution as it’s proving to be a weak point once these cars creep up in mileage.
Above all, if they’re looking to do motor rebuilds, they’ll hopefully find a way to source and stock parts which have been difficult to find at best…that will help us all. Example: 079 103 483 R
I saw that thread, price went up since 2010… The cover retails for $840 now, cost is $600…makes me less motivated to replace that one, so here I am with a new right side gasket for $24, and no left.
Sorry to derail…back on track. Bout them RS4 blowers…
Speak with deltav or horsepower on here they stripped my B7 engine about 8months ago. Richard was highly impressed with the engine from the factory and thought maybe only the rods would need to be upgraded for big power. The engine they stripped had done near 25k with various blowers strapped to it and me kicking the shit out it daily and was still solid
ROFL at the PieceofExpensiveShit!! They were melting engines with the m90…imagine how many engines they will fuck with this larger charger! PES cant tune for shit and their kits are poorly engineered. Streamline industries did a PES RS4 a few years back and the kit came in one big box all jumbled up with NO instructions…finally once they assembled it of course the car didnt run because of the fail tune.
How can people buy from that company??? There are soooo many horror stories I don’t know how they stay in business. Not “oh but there’s 2 sides to the story”, just straight up blown engines from garbage tuning. I shudder to think I almost bought a kit from them when I first got my car, they offered me a really good deal… but it was a little too good so I did some digging and stayed clear.
