n balbach Posted December 1, 2008 Share Posted December 1, 2008 I want to fit a brise kidney shaped tank with a cc dry sump system for a k series.Can anyone tell me how much extra the bottom engine pulley protrudes from a normal wet sump k series once the dry sump belt is fitted as brise do not have this measurement only the measurement for the pace system?

n balbach Posted December 1, 2008 Author Share Posted December 1, 2008 Thinking about it. Can someone with a caterham k series dry sump system please measure the total width of the alternator pulley and dry sump pulley and post it up on here. I can then work it out for myself if that makes it any easier Link to comment Share on other sites More sharing options...
Mick Day Posted December 1, 2008 Share Posted December 1, 2008 The pulley protrudes enough to make it impossible to get a socket/spanner on the pulley bolt with the tank in place. If this is what your thinking about get Brise to make a step into the tank to allow this. It has been done before for Mick Smith. Sorry not near my car to take any measurements. However I do have some pictures & a copy of the original tank drawing. Blatmail me if you would like copies. Edited as didn't read you're using a CC scavenge pump, however the dimensions must be similar. Edited by - Mick Day on 1 Dec 2008 17:04:45 Link to comment Share on other sites More sharing options...
Adrian Williams Posted December 1, 2008 Share Posted December 1, 2008 I thought the bottom pulley was the same be it wet or dry sump. Certainly I converted from one to the other and didn't have to change the pulley. Adrian Link to comment Share on other sites More sharing options...
Mick Day Posted December 1, 2008 Share Posted December 1, 2008 Adrian: you're right. Wet sump does not use the outer pulley wheras the dry sump scavenge pump is driven by this pulley. In the PACE set-up the redundant outer pulley is removed & replaced by a pulley supplied by PACE here. Link to comment Share on other sites More sharing options...
rj Posted December 1, 2008 Share Posted December 1, 2008 Some engines won't have the tandem pulley. Link to comment Share on other sites More sharing options...
oilyhands Posted December 1, 2008 Share Posted December 1, 2008 Neil, Your engine has the dual (stock) pulley. The outer smaller pulley is used to drive the CC drysump pump with the pump mounted in a Rover power steering cradle on the offside lower part of the engine. I have a spare cradle here if you dont have one. There is sufficient space to accomodate the pulley and the brise tank.. just.. Oily Link to comment Share on other sites More sharing options...
n balbach Posted December 1, 2008 Author Share Posted December 1, 2008 Many thanks all this now answers my question. Mick Brise had already send me a drawing with the bottom step removed to access the pulley bolt but they were a little concerned about the reduction in the oil capacity of the tank Link to comment Share on other sites More sharing options...
Alaskossie Posted December 1, 2008 Share Posted December 1, 2008 Mick, Can you e-mail me the drawing and photos of the Brise tank that you mentioned you have? I am currently specc'ing a Brise tank for my 2.3 Duratec with internal Cosworth dry sump bits. I don't think I will have the clearance problems mentioned, but would like as much information as available before I order the tank. Thanks.

Mick Day Posted December 1, 2008 Share Posted December 1, 2008 Neil: there's more than enough capacity in the "standard" Brise tank; at least 7 litres all in. The small reduction the step introduces won't affect lubrication. Alaskossie: Blatmail doesn't support attachments so send me your email address & I'll send them to you.

Alaskossie Posted December 1, 2008 Share Posted December 1, 2008 Mick, Ii can't seem to get into Blatmail, so I'll give you my e-mail address "in the clear." It is: tmeacham@gci.net Thanks! Alaskossie Link to comment Share on other sites More sharing options...
I.Mupferit Posted December 2, 2008 Share Posted December 2, 2008 Alaskossie, I had the same Cosworth sump as you have, and the Brise tank in my 2.3 Duratec installation and you definitely won't have any clearance issues. The kidney shaped tank was originally a Mick Attree development for his early Duratec installations and whilst it is a 'snug' fit, there is still room around it. Just a point, Brise don't normally include a temp sender boss but it is worth having one fitted at the time of the build in case you want to fit a temp sender later.

Alaskossie Posted December 2, 2008 Share Posted December 2, 2008 Brent, thanks for the "hands-on" advice. i am planning to have the Brise tank fitted with both a temp. sender boss and a boss for an in-tank heater element. Tom Alaskossie Link to comment Share on other sites More sharing options...
