-you're doing it wrong

Post screenshots? (print screen, paste into paint, save as jpeg, upload to web/gallery)

Same shell.

720 fits with fairly mild persuasion. 270 will lift the boot floor. Stako valve boxes stick up above tank level further still; I was annoyed by this!

S/H tank off fleabay? Plenty of P38s with compatible tanks heading to the wrecker at the minute...

Don't for heaven's sake run any ...

A photo of where you run those pipes Simon? You would never run a pipe between the supercharger and rocker covers.

Supercharger is in the centre. Outboard of these are intake manifolds. (short stubby affairs that the fuel rail is mounted in) Above the intake manifolds are the plenum chambers ...

8,000 miles in and it's averaging about 17 mpg or about 17p/mile at FloGas prices. Nothing much to report other than petrol use in winter on short journeys of ~10% with changeover set to 30C.

Cold weather update:

Frigging the temperature sensors to tell both the car's ECU and the LPG ECU that the engine is "fully hot" when it changes to LPG is working fine even below 0C. Heater is absolutely pants with the vapouriser in parallel. Demists the scren but you're wearing hat and gloves for ...

AC Stag ECU are more capable than the AEB ECUs and far easier to setup IME. Prices, in spite of what UK might suggest, are almost identical between Stag and AEB kit. Having tried both Stag and AEB, I'd go with the Stag.

I'd buy the cheaper "300 ISA2" version rather than the "300 Premium" version ...

Vapour pipes for injection systems are "high pressure" according to COP11 are they not? (strictly speaking - they are over 0.2 bar) Therefore same rules as the hard pipes.


Plastic cable ties are ok for cables in low temp areas. Most are made of nylon and the glass transition temperature for nylon ...

Ck8 linked above, right click save as, upload to ecu, modify settings to suit your engine. HTH!

Pressure is low - nominally 21 mbar (0.021 bar) - and the capacity depends on the meter installed.

A "typical" meter fed from a "typical" low pressure supply is limited to ~64 kW. That's heat output, not engine output. Assume 20-25% efficiency for your generator so that supply might run a 12-15 kW ...

I'm running parallel.


Gas as below on mine. Balancer pipe is after the pressure/temperature sender as it has a smaller bore (10 mm) than the filters/tees (11 mm) or the pipe (12 mm). A 6 mm balance pipe would be plenty if the fuel rails had 6 mm outputs spare. Alternative layouts are suggested on ...

You can fiddle with all of the above annoyances to your heart's content on the 300+/ISA2 ECU. The "Premium" option with OBD is £20 or so more, if you want yet more things to look at and the Supra supports it. Some screenshots in the Daimler Super V8 thread in the "tell us your story" section.

For ...

Most of the suggestions relate to longevity and cold climate performance .. "you ain't qualified to comment on those yet" :wink:

True... ...however:

There would appear to be many PRINS and BRC installs that flout all the "rules" (upside downs and horizontals) without appearing to cause longevity ...

The "if you were to do this all over again" thoughts.


ECU

I'd use the Stag system again, but I wouldn't bother with the OBD connection. (use the ISA2 not the Premium ECU)

I wouldn't put it on the driver's side of the car and make the connections in the engine bay. I would put it on the ...

Update on this:


Still running with the supercharger disconnected, pending finding a replacement one. (the coupler was damaged so replaced the coupler which cured one horrible noise, only to highlight another bearing noise)


The LPG is otherwise finished though, returning 17 mpg on gas in mixed ...

You can buy HANA injectors on a rail:

And the results are in:

First fill (faffing around mapping) got 23 mmpg over about 45 miles. Another fill after a week of faffing around locally also got 23 mpg in town. On the long run from Pembrokeshire to Nottingham he managed 30 mpg on gas. Both are less than petrol, but not as much less as ...

The Type Approval is absolutely invalidated. It may well be if a testable item is modified but when is Type Approval checked? At registration and never again after.

This is what the proposed changes are all bout. Bringing the "has this been modified since it left the factory" into the testing ...

They checked with VOSA and were told that if the work was done prior to it being registered, it would invalidate the type approval so it would not be possible to register it but what you do once it has been registered doesn't.


I suspect what they actually said was more along the lines of:

If ...

If you touch a monocoque (even with a self tapper) or interfere with the OE fuel system in any shape or form (splicing wires) then you render the approval null and void. Technically.

Ditto welding a repair patch onto a vehicle for an MOT. (replacing an entire OE panel with another OE panel affixed ...

From a simple read through it appears that it's a case of putting 2 and 2 together and making 76.

The ACE like doing that. :(


Guaranteed It will achieve zero (barryboys aren't law abiding anyway) and annoy many (the rest of us). It's like whacking a 20 mph limit, speedbumps, and a speed camera ...
