Bish - great idea with this thread. Maybe we can put something together out of this thread and mate it a Sticky for Car Preparation on the strip etc. We will do a seperate one for the circuit, as I personally think that circuit racing is harder on the whole car in general.
I\'ll try and help out here if I can.
I can only really go on what I have done myself, and what I have seen at the Drag track for car preparation (been a while since I have run a car properly on the 1/4!).
As the hp starts to increase, all sorts of problems in the driveline start to occur. But also at the engine itself. I\'ll start at the engine and work my way back.
Tuning has to be the number one thing, but also all the things like regular maintenance are important. As many of you guys drive your cars on a daily basis, a lot of the small things are sometimes forgotten before going to the track.
* Make sure your oil/oil filter is changed regularly.
* Oil level is ok (3/4\'s to full is perfect) - no less no more
* Make sure your plugs are reasonably new
* Check coolant levels
* General visual check over the engine bay
Probably goes without saying, but have any of those small problems corrected that have been bugging you like oil leaks etc.. If you think something isn\'t right like strange noises from the engine, missing in top revs, slight hesitations etc. - then forget it, something is bound to go wrong.
As for keeping temperatures down, when you are in the staging lanes - push the car whenever possible, it all helps. Moving on from this decent front noses, bonnets, intercoolers, cold air intakes start to become essential.
Tuning is important, and extra important with a rotary engine - as even one detonation can kill an apex seal. All those things that have been said over the years still apply here. e.g. If you have a standard FD but a large exhaust on it - then you may get boost spikes/creep etc.. So have it checked with a proper boost gauge, and wide-band lambda sensor for rich/lean indication preferably on a rolling road.
All the other things like a good fuel system need to be in place, if you think your injectors aren\'t flowing what they should be (i.e. hesitation at various revs etc. then don\'t bother racing it - have it checked, it may just be that the injectors need to be pulled out, cleaned and flow tested). Use things like a Fuel Pressure gauge to check pressure is a good idea (even a temporary one).
I\'m sure there is a load of other stuff - please feel free to add (I got some other stuff to do now...).
Some of the guys with big hp are now finding problems in this area - this becomes even more apparent at a properly prepared drag track. FD drivelines are reasonably strong, but were not designed for 400+hp and sticky tyres with 6000+rpm launches. Back 10-12 years ago we found this out with the older Mazda\'s here in Oz, in the time I owned my RX-2 I would have changed the diff. around 5 times, and went through countless numbers of axels. It was inevitable that Ford 9inches needed to be installed etc. - almost every quick Rotary Powered car in Oz now has some kind of extra strong aftermarket differential. Many people are also running auto\'s now, or again stronger gearboxes.
Sorry - have to fly, will post again later.
