Ep6 - Jaguar E-Type triple SU carburettors

[@jamesrickerby2756]

Got a mk11 with au,s just thought I check before mucking around it's got 3.8 e type engine in it now, so thought I'd watch your excellent video to make sure I am not buggering any thing up. Thanks guys good video and well explained.

Thanks James, I’m going to do a film at Classic Engine Workshop in the next few weeks about stripping and rebuilding the E-Type triple carbs. Might be useful if I can get it done in time!

Added this to my Essential E-Type/XKE Videos playlist. Very well done bravo.

[@fossewayclassiccarworkshop]

Coming you that’s praise indeed, thanks! I’ve an episode with Roger to follow focusing on the XK engine.

A great topic and a great restoration project. Filmed at a good pace and highly absorbing. Wish you all the luck and hope that you get this car back on the road soon.

[@fossewayclassiccarworkshop]

Thank you Simon very kind of you. I’m hoping to strip, clean and rebuild the carburettors at Classic Engine Workshop to go through the details Roger and I discussed.

Wow!, I've owned my '68 E Type OTS for 35+ years & of course worked on my triple HD-8s. This video taught me a thing or 2 for sure. I'm running an EDIS Ignition system so my spark plug gap is ,050. Also 1 7/8" intake valves and this week I installed a Bell SS 2" big bore exhaust system. I drive my car a bunch & each time I fire her up its almost like a Merlin coming to life. Life is good !

[@fossewayclassiccarworkshop]

Your car sounds fantastic (I’m sure literally with those triple HD8s and the new SS exhaust!). Please keep following, there’s a lot more to come on this project.

Back in the day it was always my speciality tuning Jaguar carburettors. 4 carburettor V12 was always my favourite to tune as you could turn a pigs ear into a silk purse for the owner.

[@fossewayclassiccarworkshop]

I’m sure! Hardly anyone has those skills anymore. I’ve just been tuning my ‘68 S-Type with only 2 carbs which is challenging enough. Looking forward to getting to work on the triple HD8s on the E. 😎

I have the triple SU Carb set up on my Jaguar powered Special and I have changed now the fuel is fed to the carbs. My fuel line goes to a blanked tube about 4 inches long, one entry pipe into this and 3 exit pipes on the opposite side which then feed to the carbs individually. The original setup can cause starvation to the front carb on hard acceleration as I found when used in competition. Another tip is to put a little oil on the fuel line banjo to stop the fibre washers drying out when the car is laid up.

[@fossewayclassiccarworkshop]

Thanks for the tips! I don't think this car will be getting track use but I have heard of the front carb being fuel-starved before. I'll bear it in mind when shaking down the car and engine/carbs after rebuild.

A comment about vapor blasting carb bodies. Many shops in my area have stopped that process because it can trap abrasive, esp in the small channels of the Webers. So a better alternative is to walnut blast then clean, this also prevents dulling of the surface and embedding of material into the bodies.

[@DAT240Z72]

After vapor blasting; the anodizing needs to be replaced. Otherwise the aluminum will darken and turn to that dull gray color with white corrosion. I’ve found Cerakote C-Series to be a superior coating to anodizing and keeps engine bay heat out of carbs.

[@fossewayclassiccarworkshop]

I’m pretty sure there was no anodising originally involved in the production of these carbs or the intake manifold they mount to. That does mean as you say they’ll tarnish over time. Not saying that’s part of the charm but it’s certainly part of the experience! 😅

[@jamesrickerby2756]

Got a etype engine in my mk2 but I should have put 3 weber dcos 45 type, I think? would you not do the same?

[@jamesrickerby2756]

Sotty you covered this DOH.

[@markdaugherty6378]

Seemed so complicated back in the day, I could never get mine even close to that clean.

[@fossewayclassiccarworkshop]

Yes, Roger takes it to another level. I have restored carbs myself before but his knowledge and equipment make them better than new. We have done another episode on the XK engine too, coming soon…

[@andylaws4247]

I think Cadmium plating is illegal now?

[@fossewayclassiccarworkshop]

Good question. I think it’s possible at a select few places if you have the right contacts.

[@ephraimchikanda5743]

Can i have the diagram for fuel

[@fossewayclassiccarworkshop]

Hi, do you mean a complete fuel system diagram or just the carburettors?

[@parttimetourist]

If it was mine I would put webbers on it

[@fossewayclassiccarworkshop]

Interesting, why? Well setup SU’s should be pretty much as good as Webers. I personally prefer them for their original fitment and look.

[@racketman2u]

@@fossewayclassiccarworkshop can't see how; triple webers are the same as SIX SU carbs; individual throttle runners for better mixture distribution and the accelerator pumps in the webers make for way superior throttle response. This is why the racing Jags use webers, but they are better for road use as well. My Datsun 240Z was night and day after swapping the 2 Hitachis (SU) for triple Dellortos.

This bloke may know what he is doing but he is pi**poor at explaining what is going on. Aspects of the SU carburettor's operation he didn't eve touch on, leads me to believe he is not fully across his brief.
