Hello all, I'm a brand new member of the forum having seen so many links here from 350Z discussions around then net. This seems like the place to be!
I'm a member of a small privateers racing team and we're in the process of planning our 2015 endurance racing season. The decision has been made to buy, prepare and race two 350Zs in a 7 race UK endurance series. This is us:
http://www.shorsec.c...of-remembrance/
To add a little spice to things we are a racing team with a specific aim: we work exclusively with the charity Mission Motorsport (www.missionmotorsport.org). MM is a charity some of you may know, they utilise all areas of motorsport to help in the rehabilitation and retraining of wounded service personnel.
As part of our work with the charity we will be inviting 2 MM beneficiaries to join us as drivers (each car has 3 drivers for endurance racing). In addition we'll be using MM beneficiaries to help in the race prepping of both cars and then a whole host of jobs: mechanics on race weekends, race managers, logistics/support roles, charity ambassadors etc. This has some bearing on the questions I've asked below because we want to buy two pure road cars, not something that has already been race or track day prepared. A big part of this is the inclusive and team lead build up to a race season - simply put we want the beneficiaries to assist in turning two boggo road cars into full on endurance weapons from the very start.
So questions specifically on the 350Z:
The class we'll be running in is pretty simple. Cars must have a maximum of 360bhp at the flywheel, be 2 wheel drive, must weigh a minimum of 1200kg and will have to use an MSA approved control tyre (likely a Michelin or Bridgestone). Nearly everything else is open up to and including aero, forced induction, silhouette etc.
Q1) What is a sensible power figure to achieve from the NA engine (i.e. without adding SC or turbo)? Endurance racing is first and foremost about reliability so keeping the car normally aspirated would be a good step in this direction.
Q2) What sort of weight figure is achievable? The car would be pared back to nothing - all interior and sound deadening gone, a single light carbon racing seat installed, multi point FIA welded cage, all aircon out, all non-necessary electrics out, all glass bar the screen replaced with lexan, possibly light weight composite panels etc.
Q3) Electrics - obviously with the airbags, stereo, a/c etc all taken out this can mess with a modern car's ECU. Has anyone had any experience of this? Would a bespoke loom be required or could we delicately hack away at the existing loom? Obviously don't want to end up with a dash full of lights or, even worse, running issues.
Q4) Catalytic Converters & exhaust - these cars will be pure race cars and not road registered. Does removing the cats cause issues with back pressure or are they easy to just bin? We need the cars to be below 105dB at 3/4 revs, that's the only consideration.
Q5) Suspension & dampers - is there a proven race package available? Interested to know if anyone sells kits.
Those are the immediate questions, we'd really appreciate any advice on any or all of the above.
Thanks gents, this is a fantastic forum and resource you've put together here.
