how do you get it nice and big and round? what did you use to shape the sheet? im assuming u started with aluminium sheet?

[Craved]

looking at it, it was a half tube for the round section

hammer and doly or english wheel for the other bends ..

please correct me if im wrong though

its a half tube with sheet metal welded onto it, its welded on both sides so that i could remove the welds on the outside with out the plenum leaking

What calculations are you using to determine optimum plenum volume and runner length?

I like the windscreen wiper bottle. Please PM me some more details and pricing.

it comes down to wat the customer wants to do with the car

ok so i was wondering about one of your plenums for my rb25/30 combo the main reason i want one is to solve the bonet clearance issues that the stock intake manifold has. ill be aiming for around 300rwkw and was just after a price and also was wondering does it use the stock throttle body and cable and also where does all the stuff like your acc valve (idle control) and the rest of that stuff go vacume hoses ect thanx in advance i will be looking at getting one in the near future so hope you can help.

Saw you post this link in a thread. Do you actually have any real world results from cars. I have a std RB20 which needs a little help making a bit more power. Dont want to lose any mid range torque though...and my fear is moving away from the long std runners will hurt me in the mid range? Any experience with different RB20 setups? Im running a TD06-20G making 260rwkws on 18-19psi

^^^ as above, lets see some before & after dyno sheets showing no loss of midrange.

Shaun @ Boostworx has even seen a RIPS plenum hold back peak power over the stocker - so after hearing that i need real world results before money is parted.
