The QV has a volt meter, the jalpa an ampere meter, different gauges (I owned both cars).

Thought you guys may want in on this conversation between Jalpa_Aus and me. It's getting pretty fun. I hope Jalpa_Aus begins a thread when he starts his rebuild! I'll be disappointed if he doesn't! Ya, I'm talking to you Jalpa_Aus!

Jalpa_Aus's Comment:

G'Day Ross,
How's the progress of you Jalpa going? I see you had problems with the amp meter from the lamborghini talk site. How close to firing the car up are you and "That first Drive"? :-)

George has given me some good pricing on the stainless steel valves and the gasket set.
Do you know what gaskets are in the kit, George advises that it is all gaskets, o rings and seals?
George said he will send a photo through so just waiting on that.

My reply:

George tells me he got my engine block and heads back from the machine shop this week. I was pretty happy and thought maybe I'd have a really merry Christmas. Then he told me that all he could do for Christmas was wrap my block up and put it under his tree. I told him that I would be celebrating Christmas at his place then! After waiting 34 years to own a Lamborghini I guess I can wait a while longer.

Here's a good point to remember. One of my cam journals was wiped out and needed to be built up and machined because the cam chain tensioner was over tensioned! Some one was over agressive on the adjustment. Be careful because the tensioners can't compensate for over tension.

The lady I bought my Jalpa from was told the alternator was out so the car wouldn't start. I didn't care what the problem was as I was going to tear down the engine because of the valves. Turns out the alternator was fine. The engine wouldn't start because the Amp Meter was fried. It was melted. She was lucky the thing didn't start a fire! The Amp Meter is not available and has been replaced with the QV Countach Volt Meter. I can't tell you how happy that makes me. The Volt Meter is monitoring the charging system through a parallel circuit so if it goes out nothing happens. If the Amp Meter goes out it shuts down the whole car or worse, it can start a fire in the dash, because it has to be wired in series with the charging system. In other words, all the current the alternator creates is pulling through the Amp Meter! Bad thing to have in the cabin!

I'm glad that George is helping you out. I'm planning on stopping in tomorrrow to look at my block and heads. I'll get an answer for you tomorrow on the gasket set. It could be just the upper gasket kit.

Remember that if you are going to tear into that wonderful piece of art that it would be a good idea to go into the bottom half and take a look around. There are a couple of main (crank) journals that need to have the oil passages opened to insure good lubrication in the bearings. I have no clue as to why Lamborghini didn't do this. My bearings showed that they were starved for oil. Also take a close look at your lower sleeves on your pistons for "piston slapping". My front set of pistons showed unusual wear contibuted to excessive heat. And all of my pistons showed excessive wear do to rusty sleeves because the engine would set for long periods of time without running (22 years and only 15,000 miles).

Take a look at the Lamborghini air boxes I received today. I spent alot of money on something that looks like it came out of a vocational school shop! Picture #1 and #3 are showing some air tube that I've not seen in any other photos. What do you think? I have no clue what that tube does. I'm trying to decide if I can remove it. Maybe this winter I'll have my machine department make some air boxes out of billet aluminium.

I'll be designing a custom Filter Box this winter to feed the air boxes as Lamborghini doesn't have any original boxes available. I'll make sure I fill you in on that too. I've got to get that scoop functional again! If you want a fake air scoop buy a Shelby! If you want a functional scoop buy a Lamborghini!!!

Okay, I really hope you guy's fill my in with your comments! Especially you, Raymond! Help me make sure my comments are correct or straighten me out.

Sorry, I'll get the pictures formatted for the sight on Monday!

Have a great weekend!

Can you ask him if he can source a pair of Urraco P300 airboxes?

It must be common to run all of the power through the amp meter. The Detomaso Pantera is the same. I look forward to the pictures Ross. Is there any (reasonable) hp increase projects that George can do?

Cam journal or lobe ? The Jalpa cams ride in the aluminum of the actual cam carrier of the cylinder head. There are no “bearings”, unless you enlarge the opening and modify it for needle bearings.

If the lobe is wiped out it is due to improper hardening (courtesy of Lamborghini), or in rare cases a cut-off oil supply; although the cams/lifters can get by with quite a limited oil supply without damage.

Of course it is, it's simple electricity, current is the flow of electrons, therefore you have to measure this in line.
Volt is a difference in the potential, this difference can only be measured in a parallel circuit.
That's the reason why a voltmeter is for save everywhere, since there is almost no current running through it.

Of course you can measure the current alternatively by using a system which measures the magnetic induction of the flow but this is much to expensive for a car.

Raymond,
I pointed Ross in the direction of www.lambostuff.com for the jalpa airbox's and base plates. I don't think Ross is too impressed with the quality of the build though, Ross's also came with an extra pipe on the side of the air box which we weren't sure what it would be used for, it was a questionable attachment but I guess it would be functional if Ross knew where to attach it to, hopefully Ross will post a picture up so that people can give there opinions for its functionality. I haven't had much to do with sourcing Urraco parts and my quick search on lambo stuff didn't show anything.
Mike

PS: Ross, yes I am planning on starting a thread when I start the rebuild, hope I can do as good a job as you and the others have done :-)

thanks Mike !!

Raymond,

last time I checked for my P250, the factory actually had some of the pieces and they weren't particularly expensive. You might check, they might have even more for the P300. Do you need everything or only selected bits?

Best regard,

I will give a try, I need "only" the boxes above the carbs.
