JHM just acquired a B7 RS4 for more R&D and track abuse (Offiicial build thread)

[dparm]

2nd on the headers. The try Y design isn't going to leave power on the table like the B6 S4 did. So Its just not going to be a good investment. Espically after seeing the RS4 headers stock. There more then good enough



You want to build parts to support the turbo and Supercharger. They did this on the S4 with the supercharger. They have the headers to help the car make gobs of TQ down low. They have the oil cooler to make room then they have the crank pully that came out of the need to design a custom crank pulley for the blower then the itnake manufiod and spacers are to keep the temps down and to free flow the intake system so they can keep the boost down.. Its fricken PERFICT. well thought out

That's my point...if they're throwing supercharger-specific parts on before the SC is installed, they're not really going to get much.

I was hoping they'd chime in.

so why wouldn't they build out what they could when their parts are currently available? That's like saying "hey, i'm not putting headers on my b6 s4 because the supercharger isn't on yet since it's not going to give enough gains."

Just wanted to mention something that I forgot in my original post.

I bought this car to help support the people that support us. RS4 guys have been buying JHM products for a long time now and they have been asking for more support. Much unlike other companies that make a quick buck doing one mod on a car that does not belong to them and/or lean on a customer car in the hopes of making a good dyno sheet.

We decided we need to get a car and beat the piss out of it. Actually own the car so when customers call we already know the little issues with the car we drive daily. If we are going to help push the platform we are going to do it on OUR own car and not put you at risk.

This is our dedication to the platform.

Confused, why go FI after you've already put other parts on? Why not build the other parts around the turbo/SC?

That is exactly how we build our parts actually. Notice the b6/b7 s4 platform, almost all parts work with each other. All parts enhance one another as well. We know that not every wants and/or can afford every single bit for their car, so you have the option to pick and choose to suit your needs and budget. So if one day you decide to step up to a bigger power adder you will not have to sacrifice another part you paid for in the past.

Can't wait for the exhaust. Please make it with oval tips if do-able and make a valved version to retain S-mode fun.

Oval tips yes, valved no. This will be a performance exhaust system only, no gimmicks or tricks to help sell a system.

For lightweight wheels look at Yokohama racing Wheels. 18 inch should be around 19lbs and 19 inch should be around 21lbs. Put me down for the lightweight pulley and intake spacer. Headers really would have to produce awesome results before I would consider them, the stock ones are pretty damn good and Super Sprint is having a hard time getting more power out of theirs over the full rpm band. As for F.I. we all know Turbos will not fit so I am guess Centrifugal Super Charger (or think VORTECH V-5 F-TRIM SUPERCHARGER ) and some new oil cooler/cooling system :P As for tune, I am on it :)

Thanks for the heads up on the wheels! I am curious to see if my 18" ssr comps will fit, they may be close to clearing the 380mm kit. I am also eye balling a set of 19" ssr comps as well but I will definitely check those wheels out.

Sorry if there was some confusion in my original post, when I stated "header back" I meant from the headers back but not looking into replacing those at the moment. Maybe when we get heavily into the s5 platform but we will cross that bridge when we get there.

Thanks again for all of your support from day one!

Spacers, and anything to keep the intake manifold and/or intake tract away from engine heat (perhaps a shield around the MAF) would be HUGE pluses!

Moton?

That is the plan, I think the gold shielding we use on the b6/b7 manifolds will help a lot as well.

Suspension companies name does not start with an M ;)


To everybody else thanks for the support! We are very excited to see the real potential of this car!

I can virtually guarantee you'll have problems with 18's almost none will comfortably clear the 380mm brakes... i've got the Brembo GT 380mm kit on my A5 and I barely clear some 19" wheels.

Right up there

Agreed, it all builds up.

I'll let ya know when I get one

Hell yes count me in. Love the enthusiasm and dedication to making quality parts for a car that really needs some in the marketplace.

Just please dont post a video of some dude driving really slowly around a track claiming how fast the car is.

I second this. We should start a pointless video hater club.

Exactly. Look at the B6. The intake makes almost 20whp and 20wtq you don't need a supercharger to have an intake and you don't need an intake to use the supercdharger but if you upgraded your parts you made lots more hp and built a solid foundation.

Its part of the performance primer. I love he fact that all the parts work together regardless of how far yoiu push the limmit.

So you can get great gains with the intake regardless of if your close to stock or full built blown or TT motor
