Development of our MK4 Rs for hps

[G-rig]

I read it as being the other way around - the exhaust is still the limiting factor. Gotta remember that exhaust gases are expanded intake gases - so the engine doesn't need to breathe in as much volume as it breathes out...

oh i meant once the exhaust is done then the intake will be the restrictive part.

so with wat iam thinkin.....with head work close to 400hps

There is a bit of talk on Mk5 about the ABT supercharger kit, currently coming in at 23k. That's the way i'd go, but understand the ECU's are the problem with MK4 tuning.

You should still get some headers first anyway and see how you like it (if they are proven ones).

Iam prety happy wats achieved with exhaust at the mo Greg.....its just OMG..
Not really interested in supercharge m8 N/A all the way for me...

The thing is will the headers really make that much difference for dollar matching hps????

Not really but you have to get whatever gains you can. Cams will ruin the daily drive IMO, while headers dont.

Sounds like this exhaust is good, did you get much out of it (ie dyno before and after would be cool as sound is a bit deceptive). Exhaust on the mk5 doesn't unlock much if any.. Should put a video/thread up anyway, sounds like you're stoked with it..

don't worry mate.
Trent and I can vouch for you.

Definitely a difference, all the way through. So much more freer, and eager.

I recorded some clips, but I don't have a firewire port on my computer, so they are stuck on my camcorder for now.

but you can have a listen to this one. it was done with a canon ixus 80.

JVLR32 have you looked into Schrick cams yet?
(not sure if they are worth it on a mk5 but i'd probably look at getting 264/26
