  1. Looks to me a lot like they didn't match the gear ratios to the downforce/drag setup. Seems like much too tall a seventh gear in Lewis's car. Proabably not worth 0.6s though. Jensons lateral G plot looks a little better as well. For anyone wondering, this is how I'm interpreting the data: Top line - RPM Next one down, crosses with RPM - Lateral G's Dotted line - Time delta (written on it) Square wave one - Not sure?? Bottom - Throttle position and brake pressure overlaid.
  2. These are awesome for certain things, such as bodywork etc that comes on and off fairly often. Definitely wouldn't use them on parts that are excessively heavy or may take a hit, like a floor or undertray though. Major negative in my opinion is that they aren't very tolerant of misalignment. If you want them to much locating of the part, there are better options.
  3. Can't see much of a difference in the data, wasn't much of a test though. We really need to do a proper back to back test, see what affect they have. CFD says they help, so be good to do some verification of that as well. Bit of a moot point as well, I would bet money there's going to be a rule this year saying "UWA's fairings are not allowed" or something to that effect.

  5. I believe so. You'd have to check with the organisors about the sup regs and entry rules, but it would be fine. I've driven in one event and been to a few, and there's a wide range of cars there, from streeters to purpose built machines. If the car's running now, I'd advise getting it on a track and get a few kays seat time in it, before you go with the engine build. Unless the engine builds a higher priority for you than doing track events. There's usually plenty of time to be made in driver ability and car setup before power is needed. (Hints, get best tyres you can, use some sort of temperature reader to get an idea of pressures and cambers, stiffer springs/bars are not always better, more damping is not always better)

  7. Location?
  8. How does the car handle at the moment? Does it feel soft/firm, slide lots or take a steady state corner set easy, good response or sloppy feel? How does it respond to whatever bumps/kerbs there are? What's the balance (over/understeer) like?
  9. We've used a product called fire sleeve with good success.
  10. Wouldn't work, for the reasons mentioned before. I usually only deal with NA engines, but I want to add a couple of things to think about. First, mass flow rate. The idea does not increase the mass flow rate through the engine (directly anyway, beyond a greater pressure differential during valve overlap, and possibly slightly better turbo performance, both of which would be tiny). The mass flow rate of the air going into the engine governs how much air (thus fuel) there is to combust, and so how much power you make. It's why we strap turbos and superchargers to our cars. Also, mass flow rate is a big factor in how much work your compressor does. Two, backpressure. Backpressure is undesirable, but it is a result of something that is needed, which is exhaust velocity. Fast flow exhaust gases help scavenging and VE, and prevent things like reversion. It's the reason why cars don't just run 6" exhausts, or race engines with no exhaust at all.
  11. You need to replace your muffler bearing. http://kalecoauto.com/index.php?main_page=product_info&cPath=3&products_id=10
  12. They wave flags when a car stalls on the grid. Problem with that, is that the driver is so busy that they are unlikely to see them being waved. Same issue would apply to a light in the cockpit. There was an accident at nightmasters at the beginning of the year, that was pretty much the exact same circumstances. Though not quite as dramatic (no fireball).
  13. It would make them quite a lot faster actually.
  14. What are your wheel alignment figures? Do you have wheels with different sizes/offset than stock? How much have you lowered it? What type of springs/shocks?
  15. Do you mean shot peened? It's a technique used to improve the fatigue strength of parts, and as above, unrelated to compression. http://en.wikipedia.org/wiki/Shot_peening
