  1. Just awesome... All that filming.. Still think it would be great to re-enforce the heater box suspension.. Either way wow!
  2. They are strong but you must buy them coated as they can gall. chromium nitride (CrN) is a good coating ....and make sure your guides are copper bronze. Titanium suffers from very hot flame temps over time as well as elongation of the stem. There is much more maintenance when you use Ti valves to make sure you don't drop one "unexpectedly".
  3. Caution going with Ti valves... They don't do very well in day to day cars and do wear quite aggressively. We treat a lot of them in the states for LS7 motors with DCT and WPC as well.
  4. All,' If you really want better life from both your semi metallic brake pads and rotors you need to have them cryogenically treated.. Nothing else will give you the life span, period. Proven, over and over and over again.. The one company that I found in the UK that does the rotors is: http://www.frozensolid.co.uk/motor-sport/. (no affiliation!) They seems to be OK.. NOT everyone does cryo the same. Ask how long the hold time at -195c they treat at . Should be min 12 hours. Also ask if they temper at 175c after treatment (a must). 3X to 7x the life from the rotors. Pads less BUT the cost to treat both should not be so bad. Our prices stateside are: $50ea for rotors and $20 ea for set of pads. Whats treated in motorsports: Complete engines Suspension components driveline components and of course brakes. etc etc.. Lots and lots of research and empirical data out there of this process..its been used in top secret US aerospace labs for many years. F1, Motogp, Drag racing WRC.. amongst many others.. If you have any questions please don't hesitate to ask...

  6. Our business based in California USA is now Cryogenically treating CWP for a lotus V8 owner. Additionally we are also micro shot peening for increased surface tension but reduced drag. This should increase the strength of the pieces and reduce heat buildup.
  7. Big track....Bloody high desert! Needs lots of money to make it look and feel attractive. I guess the Chinese may be able to pull it off...
  8. There it is FOLKS.. The ultimate marketing weapon is one that a future owner employs on one's self!! Be Proud Lotus.. LOL
  9. I want to interject here...HP is measured at the crank...Wheel HP is what is supposed to matter.... but NOTHING matters except for how the torque is delivered. Everyone talks about HP but it's all BS. And lotus has to be careful how much toque it delivers to the standard gearbox.
  10. He's at the factory...with his pillow..
  11. I think you guys should read this web site: www.fatcatmotorsports.com .. I personally dislike the owner! BUT... he makes some really good suspension with the Bilsteins NO adjustments... Thats because few in the road suspension business tailors things like nitrogen pressure or pays attention to the details such as spring rates and sway bar thickness when prescribing the valving... No adjustments needed when you can custom valve properly. If anything you will learn a lot about suspension tuning. Lotus does a really good job with their Bilstein shocks but they can do better..
  12. I used him to make a deckled spoiler for my M6...DO NOT USE HIM...
  13. most PFC pad compounds are considered in the industry to be cinder blocks. They are quite aggressive. You might consider a different pad manufacturer. Call a motorsport supply shop and ask them what the recommend for street and track.
  14. Porsche doesn't manufacture ANY brake components. Brembo/AP usually make all their OEM pieces. PFC that are made for racing like the Brembo/AP are a whole different story. PFC's claim to fame of ZERO DRAG is a ripoff of another company..But they work. You don't need holes. They were used in the 70's to allow the brake pads to outgas while very hot. They don't do that anymore because most pads are "baked" to cook off all the excess resins. The cracks you see are stress cracks from heat. Grey Iron is Grey Iron...plus or minus a couple of points of carbon infusion. Two piece rotors are better because they don't warp and can control heat better..usually. Get rid of ANY silicon based fluid and RUN ONLY AP racing fluid...That will help a lot in consistency in brake feel. After every heavy track day session completely flush the system. That will keep your calipers working optimally. Also, if you plan on a lot of track days then you should buy a rebuild kit and plan on rebuilding you calipers once a year.
  15. I haven't been active here for a bit so please excuse me if this was discussed at length before. It seems that Lotus aren't too keen to talk about any future models that may be in the pipeline, heck, they don't even allow too many journalists to drive their current cars....There isn't much in the way of publicity..Am I missing something? Again, please excuse my ignorance if Iv'e missed the obvious.
  16. That's my sentiments exactly.. Many companies make bold claims and their product may be awful. In my business there are lots of those charlatans and it has ruined peoples trust in a revolutionary service. I have yet to read that someone ruined their engine with this stuff. I do read people complaining about the cost..but that's because most of them are short term thinkers. If you own an exotic such as a Lotus you dare not complain about the cost of a fluid you may never have to replace and will save your engine internals.
  17. The '84 BMW does run cooler on hotter days.I didn't change anything with the system when changing over. The truck never exhibited any changes.
  18. The Evans is a very hot topic on many forums. Vulcan has brought up a good point that must be studied. I spoke to the Evans people at SEMA and they said, as you might guess, that there are a lot of "opinions" on what works and what doesn't with their product. On the older vehicles it's a savior. The newer vehicles are more complex in the way that the ECU reads coolant parameters in different areas. I personally think the product is the real deal..I use it in my '04 truck and in my M635..in the BMW it has lowered the operating temperatures. The mechanic I use to do the big stuff on my truck though it might cause problems with the ECU and timing on my truck as well. I have verified it hasn't.
  19. Great work Simon!! This is something I would love to do as well. How's the progress coming along?
  20. Chris Harris was complaining about the price mostly. Apparently the new GT4 Porker costs 8K British less. I guess the Evora in his eyes needs to be much dynamic than the Porsche in order to justify the price......We'll have to wait and see I guess.
  21. Firstly: Buy pads based on temp rating for the track. Raybestos (Alcon) makes some really nice race pads if you buy the correct compound. If you ask a proper racing distributor they ought to tell you what works best with your application. If you are using one piece rotors you will have to compromise on the pad aggressiveness or else you will crack the rotor due to excessive heat. All good track day pads dust heavily although I have heard PFC pads can down right leave a lot of muck! Brake fluid you want you should frankly use for the street as well. There are a few products that are based on a very good formula and tested with serious race teams. NOTE: you want the highest dry and wet Temp ratings! The torque I know very well. It is used on some high HP heavy cars and does not fail. The highest rating really but overkill for you application... https://www.google.com/#q=Torque+RT700+brake+fluid&tbm=shop The Brake Man Extreme 6 http://www.tbmbrakes.com/racing_brake_fluid You can buy direct from them. AP Racing: http://www.apracing.com/drawings/APR%20600%20-%20DOT%205.1%20-%20%20English.pdf That should do it!. BTW: NO SILICON!
  22. I person the car looks impressive...But it does not fit the mold of a 911 fighter. I would love to see lotus make either a carbon paneled car or even an aluminum one. I know Aluminum isn't as light but it certainly exudes quality more than fiberglass will ever do.
