I was sarcastic as hell if that’s not clear.
Man you guys are dreaming big! If you were smart you’d dump your 3.0 and get something that can actually be made faster. If your going to get into the headache of custom parts and VR6 swaps, why not just do a 2.7tt swap?
USP has had more gains from the VR6 then the 2.7T motor.
And its not realy any/many custom parts needed.
Please take no offense but I’m going to be blunt,
Halo- stay on point, this is a supercharger thread focusing on a peiced together JHM supercharger kit, its not some random companies engine swaps which are not even practical. This site is mostly JHM nut swingers, lol, not USP, Induktion, labree… whoever else any of these companies that you always bring up that are not JHM or have been affiliated in any way, furthermore are not even doing anything for 3.0’s.
Euro- telling people to sell there car and buy something else is not helpful in ANY way at all, you have no idea what peoples situations are or what they want out of their car, if anyone wanted a 2.7 swap I think they know where to look. 3.0 crowd needs support and movement not discouragement.
So far the useful info we have is…
-JHM 4.2 blower fits the 3.0.
where does the IM come from??? PES KIT?
-Big blower with good tune is the way to go untill supporting mods can be added. And Quattroworld sucks.
what tune would this be? a custom tune? cuz i’ve heard those cost 4x a tune already made.
Parts list for a 3.0 supercharger kit
-JHM blower from 4.2 kit (can even be bought seperatly?)
-6 injectrs (what size?)
-tune (custom, or JHM tune already made could work? )
-manifold (from PES kit??)
-?
This might be a dumb question but do superchargers use intercoolers?
and does anyone know if the 3.0 comes stock with an oil cooler?
Ok man, you must know it then. Have fun spending 10k plus for a built VR6, then add in stand alone engine management. On top of that good luck making it pass emissions to drive it on the street. I may sound like a dick and I don’t wish to put down anyone’s hopes and dreams, but if you guys want bigger performance I would look into a different platform. Even a 2.0t swap would get you further than dumping cash into your 3.0. No one really knows the limit of your motor and the internals so you would be taking a lot of risks pushing it. I guess if you have deep pockets go for it, but then again if you did you would probably go with a swap or a different platform altogether.
I guess I am just trying to be logical, but you mention peoples situations?? In the long run if you are worried about costs and cash flow it would be a much smarter move to sell the vehicle you have and go with something that actually has a following. Like I said being the first to do things is not cheap.
Now you keep mentioning the JHM supercharger for the 4.2. Do you have any clue on the type of charger it is? You mention the IM and where does it come from?? The JHM setup is centrifugal, it isn’t a top mount like the other you posted, therefore it utilizes your stock manifold. I’m also questioning the strength of your internals. Does anyone really know the limits? Are you prepared to find out? If so do you realize the cost of problems you may have?
Judging by some of your questions you should do a lot more research on the subject of supercharger systems or your motor in general. Buy the Bentley manual and read up, learn a little more about your platform, but I’m just explaining that nothing is cheap in this game man.
Here is the supercharger setup for your reference…

That wasn’t very helpful euro (sell and buy something good for power)
Especially coming from someone in the same predicament, arguably, owning 4.2 mpi. Play nice with the kids :). I do however agree that the vr6 suggestion is mental. It would cost more than three full B6 A4 3.0 cars entirely…and you would need a fourth A4 3.0 to install it in.
As for the JHM blower a4go, it is a centrifugal supercharger…it is not installed in the manifold. It is free standing in a way in the engine bay down in place of the passenger side aux radiator behind the fog light, and feeds the existing intake manifold via a tube that feeds into the throttle body (replaces the stock airbox effectively).
I understand Saki, but sometimes the truth is the best. If you have a guy ask how can I make my V6 camaro fast, no doubt it can be done, but after he actually makes it fast he should have just sold it and bought an LS1. I know I’m gonna get torched for bringing up domestic motors, but it’s an honest comparison.
If they have deep pockets and can donate their cars and motors as Guinea pigs like many 4.2 BHF guys did (which I personally am incredibly grateful for!!) then by all means have at it.
Maybe I should just leave them alone and shut up, not trying to be a dick guys, just want to get your minds thinking into things a little further.
Besides who would curse these guys with a 2.7t? Only the devil lol!
Thats really interesting I’ve never seen a supercharger like that, thats actually pretty cool news cuz in my case since I just paid out ass to clean, rebuild, paint, and install spacers for my IM. I will definitly have to read more on this centrifugal setup its very intriguing.
I totally understand selling and trust me not a day goes by when I ask myself WTF i’m doing, and I stare at the white and grey S4’s with 35k all day long on AZ and even wishing I had a nogoro with decent miles. But this is what I just did to my car in the last 120days of my car sitting in a shop not moving…
1st shop that had it before VW dealer in July
-clutch and flywheel all new hardware
-slave cylinder
2nd shop, VW in August,
-all cams and lifters
-t-belt kit with thermostat
-timing chain tensioner? something forget what its called but it was spendy
-rebuld IM and paint install spacers
-paint valve covers
-new plugs, coils, filters, fluids, vacuum lines and little misc broken were replaced
-power steering pump
-ac compressor
-clutch master cylinder
-4 new o2 sensors
-B7 keys
-RNS-E
-Window Regulator
-Aux Alarm control mod
-new window switches
-complete control arm kit with inner out tie rods
-new set pzeros and alignment
So I basically just bought my car again. I think the time to sell was when my flyhwheel went out, i feel like I can’t back out now… but maybe i should…no i can’t…(thats what goes on in my head).
I think everyone here knows that its a large waste of money to try and push the 3.0L NA motor.
People with deep pockets have tried and failed.
Bill the lead Tech at Induktrion has spent $10k trying and did NOT like what he got for his money.
Thats why he owns a B5 S4 that pushes around 450-500hp.
I had the choice of the 2.0T or the 3.0L when I bought the car.
I chose the 3.0L and I stick to it!
If I want a 1/4 mile car I’ll get a MK2 shell and put a VR6 Turbo in it and run 10s in the 1/4.
What we all would like is big companies to put some effort into finding Us some more power.
We as 3.0L owners know its there but can’t find it and don’t have the deep pockets to do it!
If You think fast cars get You hot girls faster think again.
F1 racers own fast cars and they get the girls because of the $$$$…
A4go, I can understand your position so I will try and add quality info if I post in this thread. Have your got your compression test re-done? because you really need to find out if your mechanic screwed it up or if your numbers are really that low. If they are that low you are losing a lot of power and throwing more parts or FI at your car is a horrible idea.
After this comment I now realize you may still be 19, ,so I guess dreaming big isn’t a bad thing. I don’t mess with cars to get hot girls, cars of any kind just interest me, but your assumption that I think the two go hand in hand is pretty amusing.
Too much TV and Car shows.
Half nakid girls at the car shows You would think thats what they want us to think to buy more stuf!
And I am way over 19.
I thing the s/c used for the 4.2 will be too big. IIRC it’s a 800hp blower, and JHM is using a massive pulley to slow the beast from over-powering the 4.2
its not thaaat big of a pulley. Well its not unmanageable. Controlling the throttle can help keep it in check as can other tuning parameters. If JHM is already ordering it by the truckload, using it for S4, RS4 and continuing on the 3.0 A4 seems inevitable
Besides I would guess that the 3.0 can handle power that is not far from the 4.2 rods (guessing if course)
The weak point on all of these motors as far as what gives up first is rods. What do were know about the 3.0 rods?
http://farm8.staticflickr.com/7032/6762308233_d4d864ccb0_z.jpg
Euro- I plan to do another compression and leak down as soon as I get her back, they said monday but I saw drips in the paint and I wouldn’t believe them anyways if i hadn’t because they are never on schedule.
I’m sure someone or maybe JHM will get one of these setups on a 3.0 an we’ll find out what it can handle, It seems like it would make sense a newer more advanced motor is going to perform better than pervious motors. Is the 4.2 block aluminum? Wouldn’t that be kinda a main conern with the 3.0 block, being aluminum? and what about a intercooler? It doesn’t look like the S4 above is using one. Would a 3.0 owner who needs some extra protection need one or even if it didn’t produce any gains wouldn’t it be a good idea to run like water meth setup? especially in a climate with killer summer.
4.2 is aluminium
Everyone used to talk about the “paper thin walls” etc. when it was new and nobody knew any better, but nobody has had a failed block.
The weak point on the 2.7t is the rods at around 475-500 whp.
the weak point on the S4 4.2 it is also the rods at about 450-475 whp.
Interestingly, maybe the best b5/6/7 stock engine for holding power is the B7 RS4 engine. With it revving to 8250 rpm, it is built like a brick shithouse. The stress those RPMs put on intervals is insane so Audi over engineered the hell out if it. We have seen a bunch of 500 whp RS4s and they eat it up comfortably. We also have seen 550 whp underground racing R8 cars with that motor…and even 600 whp on UR race gas setups. Haven’t heard of the motor complaining although it is a pretty small sample size.
Have there been any failures of the FSI V8 timing chain system? I can’t find any. Am I right in saying that we don’t anticipate any failures in the FSI V8, being an engine designed later? Another tick in the B7 RS4 column.
Hey I saw there was a question about injectors. I found this site when I was looking at building a 240sx but it can be applied to any car. basically you figure how much power you have/want/need and follow the formula. I planned to get 400hp for the 240sx and it was like 50/lb injectors or 500cc… Its based on a per injector setup. check it out.
http://www.robietherobot.com/storm/fuelinjectorguide.htm
Conversions
500cc per minute is approximately equal to 49lbs per hour which is equal to approximately 100hp.
lbs/hour = cc per minute / 10.5
lbs per hour = HP / 2.04
cc per minute = lbs per hour x 10.5
cc per minute = HP x 5
HP = cc per minute / 5
HP = lbs per hour x 2.04
Personally, if I could get 400 hp+ outta this car, i’d be happy. even better, if I could hit 10’s in the quarter mile that would be my dream. I want to keep it daily driver capable but being able to accelerate to 130+ in 1200ft and do it in 10 seconds, thats titties.
