Superchargers

[dvjones414]

Who has superchargers for the B7 RS4 + what gains have been proven?

I cannot find real results of any kits that have been fitted.

MTM
PES
VF

What are the experts views on the kits out there?

[larshs]

It's well known that with the MTM kit the gain is 120 hp to 540 hp. 0-100 km/h in 3.9 sec. Torque 560 NM. Don't know anything about PES and VF.

Holy moly... awesome!!!

How long will the engine last though?

The light that shines twice as bright...

this company, APR, is preparing for beta testing...they have a good rep in the States, and from what I've seen of PES and VF (not impressed), these guys seem to have found the plot...

time from 36 to 96 (use 40 to 100), tell me what you get...I get <7 sec, closer to 6.5 (stock from 4 different tests is 8 flat)

APR known here too - Awesome GTI, Manchester...

although at 5 psi a sc may generate >30% more power, say 140 HP or so, 35 to 40% of that is consumed by the blower and never makes it to the wheels...

so a net gain of ~90 HP is good...it's the whole elevation of the torque curve where the real gains are at...
remember, these are 12.5:1 Cr engines, 5 psi (after the intercooler) would be plenty, imo, as long as the cooler had good efficiency...
a solid 510 crank HP would suit me just fine
along with a nice 20% torque boost over the entire rev range

haha, look at it take off at about 1 min 14 secs into the video, it vanishes so fast, you can see the cars on the road plodding along, leaves them like roadrunner!

superchargers are thirsy as f*** too.

WOW!

This pic made me laugh.

EEK... That is a horror story and a half.

Yes it is, however, it seems the S/C was fine (believe it or not) just the components and techs used. The MTM one does seem to be the better option, however price is somewhat off putting (no where did I out the lotto tickets lol).

I did some research on this one, and it seems like it's marginally sized
operates outside it's limits and the eff goes way down, ie, heat of compression and parasitic losses rise

[sonny]

Damn, is this the S/C of choice in the states Auther? or do ppl mostly go for the MTM one (im guessing this due to cost)
