Back from the dyno - Pt1

OK, just ran the XD on the dyno, i'm dissapointed but not without hope!

A major supply problem was found that is not due to the mixer. Thanks to all the places I've spent hundreds of dollars with so they cam blame the mixer and try to sell me a more expensive setup - idiots.

I managed a lazy 147rwkw @ 4900RPM with 2.4inHg vac and only 22deg total timing... but even at those RPM's I was running 14.9 A/F. After that the A/F is too high to continue making power, we shut it down @ 5200RPM still making 144kw but A/F is up to 15.3. The graph tells the story, 4200RPM i'm at a comfortable 13.2 A/F, at 4600 i'm at 14.4. The system just gives up!

He called a mate of his who runs an LPG parts place and he agreed completely... something is wrong well before the mixer. I'll have to look at replacing the lines, lock off's and converter before heading back there. Even then, we might find out with the A/F sorted out the mixer will restrict the system.

On another note, i'm very happy with the new cam, even if the hyd lifters not rattling has highlighted another unnerving rattle (NFI where its coming from either).

If you want to test another converter, I've got a century M6 (just rebuilt), you can borrow for a test.

Re: Back from the dyno - Pt1

Mabye after the long weekend. If the engine survives this 3 day cruise then i'll start working on getting the gas sorted out. As long as I keep it below 4500 i'll be fine.

Re: Back from the dyno - Pt1

Hey Greg,

What size gas line are you running? Single or Double?

It really sounds like convertor at this stage. Or a restriction before there.

How many lines from convertor to mixer?

Your running a complex mixer? Or Simple?

Re: Back from the dyno - Pt1

I often wonder if the lack of really powerful LPG cars is not due to the gas but due to the tuner's lack of skills in that area. Looking at all the troubles you have had greg, a competent tuner should know his job well enough to have picked it up ages ago.
You aren't the only one battling incompetence too... there are others with LPG cars getting screwed around.
Anyway, at least you are making headway !

Re: Back from the dyno - Pt1

Oooo, nearly forgot.

Where are you getting gas from?

I don't need to mention the shite that is being sold as LPG around the place.

Have you noticed different results from different fuels?

When I was running low performance gasoline I found best results in both seat-o-pants & dyno results from a place that had a pure propane tanker for BBQ's. ps it was a caltex at the time.

Re: Back from the dyno - Pt1

Jamie, I'm running a 5/16 single line with an impco model 'L' converter and an impco 425 straight gas carby.

I use LPG from Mobil or BP, but I'm not going to tune the car to use LPG from anywhere special because its going to be for the street... and I can't be picky if i'm running empty! low performance gasoline...

Quikcorty, sorry I havn't gotten that back to you. I've been working on the car every day since I borrowed it. Only got the diff in last night! I'll try and get it over to you tomorrow.

Couldn't agree more Jeff.

I've taken the car to at least 4 different tuners and so far he is the only one that has said "this has nothing to do with the mixer".

Everyone else has just thrown their hands in the air, told me the mixer is too small and tried to sell me another system.

My current tuner actually used the dyno and his knowledge to come to his conclusion right in front of me, basically he said if it was a petrol car leaning out like that, it'd be the fuel pump or a serious problem with the lines. If it was the mixer, he'd expect the a/f to be a lot better and the vac to be much higher (although it is too high at the moment, but thats another story!).

LPG guys, be wary of who you give your cash too.
