Superchargers

[johneroberts]

This is the first pes kit we have fitted. I am not going to post results until we are finished but it has around 30 hours dyno testing on it so far - We can see why other builds have not made good times so as well as dyno results we will do some timed runs to show the gains you can get if we tune the car.

so...this was posted over a month ago. Any results?

the owner of the car said MRC had a vbox (a month ago) and were doing timed test runs 'tomorrow'. Can you share any of that data?

I've been one of the people calling for these supercharger companies (and their OFFICIAL distributors) to stop plying the public with dyno distractions and show some real results. Why is it so hard?

Very disappointing. We're not talking about a Honda Civic from the early 90s...we're talking about $20,000+ kits on $70,000+ cars here. We the consumer deserve more than empty promises and corrected dyno results that are mysteriously converted back to crank with phantom DT loss numbers.

I was banned on A5oc.com for questioning PES and their kits...for demanding more. PES' solution to shut my requests for proof up were to become an official advertiser and have my account banned.

Is PES an advertiser here? Didn't think so. We'll see if someone...ANYONE can cough up a proper performance test. It's not much to ask.

My friend owns an E92 M3 and mentioned he's thinking about a supercharger. I asked him what he was thinking of, and if they have substantiated their claims with performance. His reply was simple...

STEP UP PES/VF/MTM

Are you trying to sell this stuff?
If so i suggest you apply for a TRADE account
Lets hope you dont get banned on here...keep it friendly
Cheers

He's not selling the PES kit john, more trying to either discredit it or indeed their power increase claims in what I believe is the hope that people won't spend their money on something that doesn't deliver as significant a power hike as is claimed.

sakimano is one of the few liberal minded people on one of the other forums I know of.

Saki has got a valid point about the kits I think. In my opinion they don't seem to perform as well as you'd expect, when you compare them to an N/A car with bolt on performance parts (for the S4 anyway)

VF for example have offered no more data than a few RR charts and some dude just cruising around a track, telling you it's great over and over again and APR scrapped the idea completely and they themselves have explained why.

until you disagree with him...
I'll have to agree to disagree with your assessment ;

[P_G]

Fair enough but at least he's not bigotted like some of the others on the same forum.

that is relative...the bar isn't set very high at 'that place'
he's got a hard-on for anyone NOT JHM
look at his 'work' on quattroworld
or audizine until he (and others) left to form their own site after they were informed that the rules apply to them also...
he does like to post personal info, attack individuals, harrass via PM and make physical threats and encourage others to do so...

the point is, he does not have the expertise or knowledge to judge one way or the other...
the M3 he posted? let's see how long the engine lasts under those boost levels...KABOOM!!!!!

the PES set-up, although not suited for top end power, gives a nice mid-range gain that is suited for daily, on the road use vs drag strip racing

when was the last time you ran 0-110 on a public road, full tilt boogie?

Hey guys just signed up for this forum today after reading sakimano was still going on about 1/4 mile times! Saki if you didn't get yourself banned from the a5 site for being such a pain the arse you would see I posted videos and the times are there for all to see I ran consistent 12.3's with two runs lower down in the 12's also. Failed to mention guys it's my car that Mrc fitted the pes supercharger kit onto and as Arthur suggests the cars. Mid range torque is superb also Arthur if you go on you tube there's an Arthur test time of which the car managed to do it in around 6.5 seconds I hope it helps

[adsgreen]

Dyno graphs are "nice" but don't offer much on their own - they are subjective open to too many variables.
Same goes for 1/4 mile and 0-60, 0-100 times - too reliant on driver input to have any meaningful comparison.

Just simple in gear times on a back to back comparison is enough (so same time/conditions) and not much you can do here to get it wrong.

[ArthurPE]

I agree, the best tests, imho, are 'in gear', say 3k to 8k in 3rd.
This represents the entire power band and removes the driver from the equation (no shifting required)
it is an excellent baseline for comparitive (not absolute) results

after having thought about it, the PES system is a viable choice...
yes, maybe a bit less power, but better reliability, less stress on the system... (it is a daily driven street car, not a 'drag racer')
it is mechanically limited by its size so can't over boost if controls fail
it provides excellent mid-range (and wide) torque boost, the area you spend 90%+ of your time, and most significant on the street
factor in cost, iirc it's $10k vs $18k for the APR (no tests done yet other than 0-60 and some iffy dyno) and the MTM, a proven product, but vey pricey, $25k?

so, if you have realistic expectations, are pragmatic, and seek street usibility/reliability as much as peak power, the PES may not be as 'bad' as everyone is trying to paint it...

Hi Arthur I take it the test ur after is an Arthur test? This has been done and it's on YouTube it took 6.5 seconds in 3rd gear to do 30 to 100 or so mph. I'll be honest and say I ain't sure if that's good or not but I suspect that it may be

yep, saw it, and timed it a dozen times myself with a Speedmaster Moonwatch, the angle is a bit off, so requires a bit of 'judgement'
I came up with a time between 6.6 and 7 flat, so <7 sec is what I'd call it....
and that is good, a stock car will do ~8.5 in std conditions...

Ok cool I am a bit naive with certain tests etc all I know is how well my car now drives compared to when it was stock I've gained almost 150 bhp through carbon clean up as you can imagine the car is awesome now! I'll post over the coming months with regards to the cars performance etc
