Development of our MK4 Rs for hps

[McDub]

I know what you mean, but it's also good to keep your feet (and wallet) on the ground and everyone knows it's much cheaper and easier to mod a factory-turbo car than any kind of NA mods or conversions..

Also you dont have to get the latest and best, any S3 in good condition would be awesome..

I'm faced with the same thing so not winding anyone up, just have to enjoy it for what it is with some light mods, or buy something faster.. my 2c.

you serious? read the thread title!

Well ive just had talks with Extreme Exhaust here in Coffs.....built some really tuff systems....New system will be built...all the back system to the first muffler will be gone....This is all about development for hps

Ive ask Dean(extreme exhaust) wat hps he reckons=10+hps
The Cat back to first muffler not worth replaceing for Dollar to hps

Done by end of week

Can you get dyno graphs before and after? It's the only way you'll really know how much of a gain you got...

It was just a realistic alternative before throwing heaps at it, but am all for improvements if it doesn't detract from the car.

Head work....wat dollars are they worth? has any R owners here done this yet?

[Mr. JLT]

I would say mill 3,4mm out/off the factory upper down pipes that bolt to the head-give it a good gasket match. And then the lower down pipes I have seen guys cut the flanges off and go with 2 true 2.25 mandrel bend pipes down to the cats. I think bmf still sells the 2nd half custom down pipes and i think usp does too. Or spend big bucks on headers!

I think cams would be a good starter for the head work- I think fusion is selling a set of R32 cams-suprised no ones has picked them up. I also have plenty of pics for a R32 custom exhaust if u need some ideas. Cheers J

I like this bit:
"Our gas flow measurements show that it has very good inlet flow but there was a lot of room for improvement on the exhaust side. After a challenging and extensive period on the flow bench we were able to raise the Inlet flow by 6% to 161.6 CFM. On the exhaust side we were able to make a huge increase of 30% to 129CF. This level of flow means this engine is capable of over 400BHP in normally aspirated form."
