  1. Yes your right the brace is connected to the turbo flange bolt on my car as its the early manifold but new ones have a dedicated bracket. The brace has a rod end bearing either side allowing it to move with expansion. Your point about the steel shim style gaskets , if you use cheap studs and nuts they stretch under heat and then start to come loose when they cool off and go through the heat cycle again. The kit comes with right studs and nuts and I haven't had any problems so far and been over a year now.
  2. As far I know that includes VAT, but if your interested if we can get a group buy of 10 then the price will come down to £850. All the gaskets stainless studs and nuts are included in the price. Alunox make full systems for the racing teams , the gaskets are made of the same material as the Cosworth F1 series cars and the Lotus Type 72. I have to say this manifold not only eliminates the problems of the cast one which I believe is £831 from Lotus, but also enhances the drive of the car at weather you’re driving it hard or even taking your time you will notice the difference. So if anybody is interested let me know, on here or e-mail me on [email protected]
  3. No sign of cracks , it is made of a high grade of stainless steel 321, would be good to put on dyno as power increase is noticable along with quicker throttle responce. Its also has the effect of reducing the lag due to the quicker spool up of the turbo. The gaskets come with the kit along with studs and nuts. Alunox are interested in group buys to bring the price down . The kit is now on special offer at a price of £990 from £1200 for a single purchase. If a number of people are interested a group buy could reduce it further.
  4. Just an update on the stainless Steel manifold from Alunox Exhausts, it’s been over a year now and I've done about 4 track days.It’s held up well and I have full confidence in it. The manufacture is now offering a warrantee on the manifold if any bodies interested, call Leon on 01978 8551100
  5. Hi , I've now had it braced as mentioned before . The manifold has to be allowed to move due to expansion . This style of bracing allows the manifold to expand horizontally whilst supporting vertically. The standard Lotus bracing was based on linking the exhaust flange on the 4th port to the turbo flange. On this style of manifold that could cause a problem due to the rate of expansion in the down pipes section being greater than that of a top brace occurring during the heating and cooling cycle. The elbow or down pipe section feeding the turbo flange is where the greatest concentration of heat occurs. If you interested in this and want to know more you can contact Leon at Alunox Exhausts on 01978 – 851100. Also he has just finished a set of manifolds for a Lotus 72
  6. I have done over 2000 miles on the manifold and the LOT track day at Donington on the 12th Aug (Evening). It hasn't moved at all as I have checked it. It is made of the 321 grade of stainless. The company who have made it ,are going to fit a brace just for piece of mind. Apparently they make manifolds for Nobel and the bracing technique used there will be adapted for the Esprit. I will post it when done. Mark.
  7. Hi ,if your still looking for a stainless Steel manifold for the stevens esprit turbo , I've just fitted one just developed by Alunox Exhausts as shown on the LotusEspritWorld website. Its made a big difference in performance and sounds better. It seems to bring together all the other mods I've made. Mark
