Re tank/pump

On my spitfire i was given a tank that had been left empty for over 20 years, no sniff of petrol so a good clean out and we were happy to weld it. Otherwise they need a good steam-clean out. We tack welded a plate  (precut a hole, and made a clamp ring for the pump, plus fitted studs to the plate for the clamp ring, which were brazed underneath to prevent petrol working its way up the threads) towards the OS end of the tank, and it was brazed. A bit if a mission as the tank is not flat at the top and has that pesky seam. Took a few goes to get it watertight, then checked with petrol.

Anyway, I used a mk4 golf pump, bought off ebay for a tenner. It is a perfect fit in terms of height, and has built in return and a swirl pot. My car has done several trackdays, a couple where the fuel level has got pretty low, and no issues at all.

 

The pump had its sender mechanism removed before fitting, I wonder if that could be utilised but would have been a further complication in terms of gauge calibration. I did use the original golf seal too, so worth finding a pump that includes it (not easy to find new, and not really cheap either)

Hello Clive

                 I must say I like the idea of the pump and swirl pot in the tank like modern cars and the pumps are cheaper(just need a spare tank or find some one to steam clean mine) the welding and or brazing would not be a problem.

Plus they are quieter and keep cooler.

Just priced a new one from eurocarparts with the 30% discount £60 so not expensive?

Plus my mates son is into VW,s big time so could find me one and fittings

 

Thank's for the advice

Hello All

             i don't arf like the look of these!!!!!

 

http://www.ebay.co.uk/itm/131905568864?_trksid=p2060353.m1438.l2649&ssPageName=STRK%3AMEBIDX%3AIT

 

But is that OTT?

 

But then I would have to build en engine worthy of them?

 

So were is my problem?

 

This wine stuff is a B*****r

 

log off you daft S*d brain says (but what does that know/)

[Clive]

Those TB's look  jenvey-esq and would be good and help on the power front. A simple and elegant solution too. Plus you could just use a std weber inlet. 

But surely too simple for a man such as yourself?

I have jenveys on my Zetec, but looking to fit an st170 engine, and then that would use a set of bike throttle bodies. (basically so I don't have to separate up my engine package, as the ecu is locked to the supplier and can't be mapped for alternative engines)

So I may be fitting something like the microsquirt myself. Along with a VVT controller. Which is why I am paying attention to this thread, my current setup was bolt on, turn the key. Far too easy!

They look lovely, but add the cost of the Weber inlets and that is an expensive solution. My conversion is on a budget, so anything like that is just not up for consideration. Apart from really looking forward to fabricating the manifold, I bought enough steel to make about a dozen for £50.....

[rogerguzzi]

Hello All

             How about these cut in half?

 

http://www.ebay.co.uk/itm/231918459196?_trksid=p2060353.m1438.l2649&ssPageName=STRK%3AMEBIDX%3AIT

 

Or 2 of these?

I still like the first ones as they come with a proper fuel rail which holds the injectors down?

I suppose a Ford engine would be easier? but where is the fun in that?

 

Roger

 

ps these look a good price?

[rogerguzzi]

Hello All

             I am really thinking of buying a set of those throttle bodies!

But which inlet manifold would be best?

Moss do two? one about 110mm long and one about 40/45mm long plus they have a 15% sale on at the moment.

You are right Clive I do like a challenge but I do fancy 4 throttle bodies as they look the Dogs dodah,s and never had a car with ITB,s and I think sorting the rest out will keep me quiet for a while!

Money is not that much of a problem its number of years left in this old body(71 and lost 2 good friends recently same age!)  plus I can always sell some Velocette motorcycle parts to cover the cost if need be and I am also SKI ing(spending the kids inheritance)

I can see the konkers lot throwing their hands up in Horror?

 

Roger

[rogerguzzi]

Hello All

            That,s it I have gone and done it and ordered a set of the Throttle bodies(I spent that much replacing my old camera recentley)

I have not ordered the manifold yet want to have a good measure of the space(from what I read longer induction tracts are better?) not sure if it makes much difference on a road car?

I have been reading the Microsquirt site information about sensors and they say it does not make much difference to use a closed sensor for the air temperature in non turbo cars?

I was thinking if the open type is just mounted in the engine bay would it get clogged up because it is not in filtered air? and water temperature types are cheap and you can calibrate then in the software.

I am sure I will go for the pump in the tank fitting with built in swirl pot.

The jury is still out on whether to use Edis or Bosch amplifier for coil pack(may be swayed as I have 3 Edis4,s)

I think I will get an adjustable fuel regulator as you can tweek it to suit the injectors so I believe?

Roger

[Clive]

Inlet length can be altered using trumpets. Easier than trying to loose some length! Also allows deeper filter. 

Then again for power you want the injector as as far as possible from the valve, for economy close is better.

[rogerguzzi]

Hello Clive

                This gets complicated!

Would there be much difference?

God this a can of worms? but makes the old brain work!

Why do we have to tinker?

I know the answer we are a long time dead and beats the s****t out of TV etc

Roger

[Clive]

Tell me about it. Can't decide to just freeze up like a rabbit in headlights!

On balance, I doubt it makes massive difference where the injectors go. But intake length, from valve (in head) to end of trumpet does. So I would be using shorter manifold, and sort the trumpet length after.

Something to wade through:

[rogerguzzi]

Hello Clive

                 I think my brain is getting worn out? here is another article?

 

 http://www.jenvey.co.uk/faq/general-faq

 

I hope it does not finish up lowering the power and torque?

 

Roger

 

 

[rlubikey]

Just going back to single-point injection, presumably it's timed to coincide with cylinders filling as opposed to free-running squirts, so to speak, is that right? So obviously it needs a timing disc on the crank, but it *doesn't* need a sensor on the dizzy, is that so? So my question is, do DIY systems like Megasquirt run happily doing timed single-point injection without a dizzy sensor?

 

 

Cheers, Richard

[rogerguzzi]

Hello All

             Well wouldn't you know by the time I had made up my mind which inlet manifold to buy(The long one not sure the short one would clear the exhaust pipes) The Moss sale had finished!!!!!!!!!!!!!!!! (who finishes a sale at 11am on a Friday?

I will have to wait until they have another sale?(bound the be one to coincide with the restoration show and I can save p&p)

 

Richard I was thinking the same as you! but now I have read this article I understand it(almost)

 

http://www.enginebasics.com/EFI%20Tuning/Batch%20vs%20Sequential.html

 

I have decide to remove the Edis4 module and fit one of these

 

http://www.ebay.co.uk/itm/331704617090?_trksid=p2060353.m2749.l2649&ssPageName=STRK%3AMEBIDX%3AIT

 

And this air temperature sensor.

 

http://www.ebay.co.uk/itm/252330110671?_trksid=p2060353.m2749.l2649&ssPageName=STRK%3AMEBIDX%3AIT

 

I am thinking of this fuel pressure regulator(not sure abut the gauge?) but probably will 

 

http://www.ebay.co.uk/itm/371436494447?_trksid=p2060353.m1438.l2649&ssPageName=STRK%3AMEBIDX%3AIT

 

Not sure which TPS yet will wait and see what fits the throttle bodies?

 

As for trumpets and air cleaners I will see what can be fitted(perhaps a collector box and one on the front as moderns do?)plus would be better for IAT sensor and keep it clean.

Hello All

             I wonder how tall these pumps are and it looks spring loaded to push on the base of the tank?

I wonder if it would reach the bottom of Spitty,s tank?(they are cheap)

ps their is several ones in the range with different fittings

[rogerguzzi]

Hello All

             I have been thinking(dangerous) about all the wiring to be done on Microsquirt.

 

I have decided to use these in the first instance as I can terminate the 35 way plug and fix it all under the nearside bulkhead and use either ring or fork end terminals.

 

I can if needed use several for one application and bridge on Microsquirt side of the block(so all single cables to plugs and no joints in engine bay?)

 

I can always hard wire it later if needed? or multi plugs?

 

I can not see it will cause problems as it will all be in the dry? and it will make constructing a harness easier.

I have ordered a pressure regulator from these people with gauge(the cheapest I could find)

I tried hard to resist reading all this and now ive got your headache     Brilliant stuff.

[rogerguzzi]

Hello Pete

                I think it is close to Wine O Clock Time?

 

I have been trying to copy the ignition map from Megajolt to Microsquirt !  the 1st is 10 x 10  and the second 12 x 12 so dreaming up numbers?

 

I am sure it will be all worth it? or an expensive folly?

 

Roger

 

ps just worked out if? I get an extra 5 mpg on 5000/6000miles per year it will only take about 15 years to pay for its self !!!!!!!!!!!!!!!

 

Still not as bad as Konkers cars?

[rogerguzzi]

Hello All 

            My Throttle bodies have arrived and they look ok and come with the fuel rails.(wonder if the Wife would mind if I put them on the mantelpiece until I fit them?) 

 

I have fitted some old injectors to just see that it all fits, 

 

I have decided to buy some new injectors because knowing my luck I would have a faulty one! found a set on Ebay for £40 inc p&p so not worth messing with old ones?

 

I have bought the Bosch 0280 155 884 type (fitted to lots of Rovers and MG,s) so if I ever get one fail it would be easy to get a spare(even abroad)

 

I have found a Rover TPS sensor cheap on Ebay new and original.

 

A quality coil driver made by Cambiare which I believe is a good make and it say England on it so assume its made here?
