Thanks Brett

I hadn't seen that thread before.

Several of the setups use the same mixer ring as on my RRc, but I also noticed that the first one still had the crankcase breather connected in the original position after the LPG mixer. This was also the situation on the donor Disco 1.
My LPG fitter was very concerned that I not use that port to the extent that I had to have a fitting made to move the breather before the mixer ring.

One wonders if this is why so many people have backfire problems on V8s with LPG (when I have had none)?

Diana

Interesting, Have you got a closeup of the fitting and where it is attached.???

All series 1 Disco's and V8 classics don't need the crankcase breather shifted, because they don't use PCV valves like Australian cars. The fumes always create positive pressure in the crankcase, so no LPG can enter the breather. P38 engines are different, they need the breather shifted. I have done a couple of Bosch injected cars with sequential Zavoli/M.G.A. systems, they seem to be running well.

I have the system I pulled off my 4.6.

A venturi on the EFI manifold and the Landi Renzo SE81 converter suitable for large engines.

See http://p38arover.com/lpg/Landi_Renzo_SE81.max (it's a PaperPort file, you'll need the downloadable viewer).

I have had a sprint gas system put on my D2 2000 at ezy gas in jan (injected) and it has never worked properly. They have had the car for more than 6 weeks over up and till now and blamed all sorts of things. The car at first run OK only on petrol but when you change to gas it trows everything out and will not even run properly on petrol. Has any one Have any ideas. Thanks Benny

Do you still have the bits and what are you going to do with them.

Along the same lines - does the P38a have a MAS and is the venturi on the MAS or on the plenum?

Hi Diana. Yes, I still have the bits and I want to get rid of them. The venturi screws onto the plenum. The P38A has a MAF sensor.

I also have an OMVL R90/E two stage converter.

Ron

Thanks Ron

We may have to do deal, but is the plenum on the P38a the same as on the D1 and RRc?
Can I fit the dougnut/venturi after the MAS on a D1 system? (This is the whole reason for this entire thread and I'm still no wiser.)

I can measure the P38A plenum tomorrow if you like.

I had a venturi fitted on the plenum on my 4.6 '86 RR (but that used a Haltech EFI system and a MAP sensor, not a MAF).
