u need a restrictor ring goes in the inletside of charger with a radius style machine finish then u open that up with a lave to allow more air to get more psi.
I have one that i could sell u, it is set for about 7psi but that can be opened up to get more power or fit a spacer plate or pistons bigger injectors no restrictor and go for it!
Rotrex Chargers don't work on pulley size = psi.
You restrict / adjust the amount of psi by putting a restrictor in the inlet side of charger.
The size of the pulley is the smaller it is quicker it spins charger giving instant almost boost! but if u are 2 wheel drive it will just spin the wheels.
What Rotrex charger do u have?
unfortunately there are no ready made pipes but by silicone and alloy bits from ebay and when your happy with the pipework get some alloy bends and have em welded up.
ok your looking at
About £1250 for brackets and pulleys from me, Rotrex charger about £1550 give or take a bit depending on exchange rate, couple of hundred quid for pipe work and about £450 for mapping
as long as your fuel pump and injectors are all healthy.
Bracket and pulleys are first bit to get then add a charger when saved up a bit more?
I can supply bracket and pulleys for a Rotrex setup and point u in the direction where to buy a new charger at a decent price!
Low boost will see u about 300 to 350BHP and high boost (head spacer or pistons) 400+ and totally reliable.
I have supplied a few of the R32 Boys with kits.
I got a 24v with Rotrex on low boost hitting 312bhp Vince at Stsalth backed it off to that figure as I do track days.
Gonna build an engine for full boost over the winter?
Anyone got a couple of old inlet / outlet vales they dont need? mate looking to do a big valve head on his T5 van already pushing 312bhp wants em just to test fit.
Cheers for any help.
So where can i find out what replacement injectors i need? they are for my 2.8 4Motion which is having charger finally fitted in May. Part number of my injector is 022906031F but i don't know what make? and i need to get 550cc replacements but the height is an issue apparently? So can you guys help me on this one as i have not had much luck today trying to find the answer. Also any advice on what fuel pump to use? I want to replace just the in tank pump.
Firstly a BIG thanks to Pete for organizing our great day out at A great day out and top crowd as always and a good chance for photos although the daughter of Hitler stopping a few nice cars going on banked track was a shame But mine made the height required And then a frantic message from Michelle to me and Doug to get back to main show area as we had both one one of these But it made my birthday( ) even more special even though i would never have guessed id win anything! Then to finish the day off was nice to head back to Bluewater with Doug Michelle Nick Gary & of course Paul
