bosbon_be 4 Posted September 5, 2009 Report Share Posted September 5, 2009 I installed a custom chargecooler and al its components. I did not fill it up with coolant yet. Before I do, do my carburators need rejetting or are they rich enough for the cooled air? Regards, Peter. Lotus Esprit Turbo HC. Quote Link to post Share on other sites
USAndretti42 302 Posted September 5, 2009 Report Share Posted September 5, 2009 They should be self-compensating in as much as the depression at the jets depends on the air density so the colder, denser air wil draw in more fuel with the same jets. Whether it will be enough is best checked on a rolling road. I would start with the standard jets and get it checked out before you thrash it.

Andy67 0 Posted September 5, 2009 Report Share Posted September 5, 2009 I always thought when adding a chargecooler to a carb turbo version it would require re-jetting ? But stand to be corrected.... Quote Link to post Share on other sites
USAndretti42 302 Posted September 6, 2009 Report Share Posted September 6, 2009 Andy, I'm not saying it won't need re-jetting. More that it may not need as big a jet change as expected. That's why I suggested getting it on a rolling road rather than just guessing new jet sizes. THe other thing, of course, is we don't know how effective the intercooler will be in this application.

bosbon_be 4 Posted September 6, 2009 Author Report Share Posted September 6, 2009 The chargecooler is a pace chargecooler (double the size of a Lotus), the radiator in the front is the original from lotus (thanks to Bibs and Bell and Colvill) Just added some picutres of the installation. It's a tight fit. Quote Link to post Share on other sites

th4neuk 0 Posted September 7, 2009 Report Share Posted September 7, 2009 In a way it depends if you are now going to up the boost with having the chargecooler fitted. On mine I had it rejetted to cope with a max of 1 bar boost after I fitted the chargecooler setup. Was good for 289bhp on the RR.
