Hi Simon thanks for that I will try the tin foil out. Glad to see you back you have been quet for a while. Saw your car at Stoneleigh, very impressed well done. You were discussing launch control with someone, have you done it yet?

Peter.

The RS 2000 head is the same as the standard 2l pinto anyway so it will the flowing that counts. I would go for an injection head which has hardened inserts so no worries about unleaded and flows better, then flow that. That is what I have done anyway with a 285 Piper cam. I don't think there is much between the well known makes of cams (stands back to be attacked!)

Peter

Dear Horncock, the mystery man, don't give much away in your member profile!

I have 12° advance at tick over with vacuum disconnected using a 285 cam on unleaded; it doesn't pink and would take more I think without problems but the old starter motor struggles. Pintos seem to like lots of advance, go as far as you can before it starts pinking.

I was very impressed with the jet car program but having missed the first half of it couldn't work out how a valveless pulse jet worked. So I found this on the web, does it look familiar to anyone?

Re mid engined car, it was at a show in sort of kit form as I remember but I am pretty certain it didn't get into production. The proportions looked a bit wrong and something that looks like a seven should be front engined, rear drive. Mid engined cars should be pretty and modern looking so there! The V12 seven? is pictured in the Sierra 7 build manual, it is a pretty poor photocopy but I could try to scan it. Someone in the club magazine was trying to buy it/track it down a few years ago. Goodness knows how it was cooled though!

Peter.

Hi Peter, RHE did make a few cortina kits with proper wishbone front ends. I know a man with one but he is on holiday at present. I don't know how possible it is to modify the cortina setup, very hard I expect but I will ask him to send a picture if he can.

Peter

Glad you got it sorted Kevin, Hi Fred the brake compensator won't have any effect on a rolling road unless you have mounted it pointing downwards. It works on inertia, there is a bit about it in the build tips on the old site it may be of interest.

Peter.

Also the brake compensator unit if fitted can be a real pain to bleed properly.

The Carb fixing stud centres for DGAV and DGAS are approx. 92 x 45mm, don't forget granadas and transits may have the correct manifold.

Peter.

Hi Andy I don't quite understand what you mean. The Dgas will have 38mm choke plates, the butterfly bits at the bottom they will be the same size. Normally it will have cast in venturi chokes of 27mm, there will be a number moulded on the outside of the body within a circle normally 27. The dgas is basically two carburettors in one and were made for V engines with one choke for each bank of cylinders, so each side of the carb will be the same.

Peter

Hi Piddy, it might be worth just fitting a new seal kit to your old one if you can get it. I recently replaced mine which is the same setup as the picture as it was leaking at the back where it joins the servo, and also where the reservoir plugs in.

Peter.

Just as an example of costs involved, 3 years ago I contacted Bedford Auotodrome, which is Johnathon Palmers set up to enquire on their prices, this is part of the reply I got. I didn't bother to ask any further, I wonder if the prices have gone up much since then?

'Having said that we are expensive for a full day hire at £12,000 plus VAT. What a few of the on track driving clubs do is hire the venue for a summer evening when the cost drops to only £2,500 plus VAT for a session from 17.00 to 20.00.

Let me know whether the members are interested and we can discuss availability'.

Jim it is only O rings and seals made from Viton (Fluorocarbon) which have this effect. but they will be used in fuel systems for modern cars running on unleaded fuel.

Peter.

PTFE Tape is proof to virtually all chemicals

Apart from stuff with high fluorine content! no problems with petrol though!

Peter.

I thought this subject was somebodys birthday coming up!

Another claim to fame for Jim, I know it was cheap but will it last for more than 15 mins?

Peter

Low temp switch, I bought it from the radiator place, I think there are 2 standard thread sizes for these things, and a couple of different temperatures. The only dissadvantage of the low temperature is that I discovered this year that when it is very hot the fan keeps running even when you are doing 70, ish down the motorway.

Peter.

This looks like great fun, I know it won't make a Hood!

Sorry don't know how to make a link either!

Hi Nelly, I use a fiat 127 rad in mine it is a new one with copper tubes and fine alloy fins, it runs fine on my 2 litre. The place I bought it from had fitted a couple to caterhams. Following his advice I fitted a low temp switch in the rad, about 75° I think. as he said if the fan doesn't switch in until the water is about 90+ in the bottom of the rad then it may be too late anyway.

3 screens and only 2 eyes? is this the visual equivalent to 5.1 sound?

Hi Boggie, re. the two bike engines on a common crank, I picked up a leaflet from Stoneleigh? I think, for Cyclone Power www.cyclonepowerltd.co.uk 01202 64911 it is a 1997cc V8 73Kg. 302 bhp 167ft/lb on carbs. I don't think they had sorted a price out then, any good?

Peter

Graham if you do a search on this section you will find a recent thread showing the id. letters to tell if yor head is for unleaded or not. The simplest solution is just to start with an injection head which will have the inserts anyway, it also has a better shape in the inlet port where it sweeps around to the valve so less work required in that area, and it is mostly the exhaust side that needs the work.

Regards Peter

I have an old valve from a dohc engine if it is the same and if you want to try it. Athough if you have tried others with the same result I doubt if they were all bad. I had a similar problem on my dohc sierra, replaced the valve with a new one and it was just the same. turned out to be the MAP sensor was dying.

Peter.
