hi iv had a search and couldnt find anything.
i have a lucas pump and done the usual max fuel and turned my turbo up slightyly.
i was wondering is there a way of increasing the max rpm on these pumps? they stop fueling at 4500? im sure i read somwhere you can increase this to 5200rpm?
any help is appreciated.
thanks tim

I've wondered this.... Mine can rev all the way to 4500rpm and reach 75 in 3rd gear! it sounds nice when proper going for it! Surely there is some sort of limiter in place?

Damn, i dont know how you guys can rev your car that hard. I usually feel guilty after 3k rpm!
Bet that will all change when modded

You could try removing the max rpm screw? On the lucas i mean.

I assume you know what the throttle arm is, so if you pull that round to full throttle it hits a screw. Thats it. lol it usually got a cover on it

I wouldnt recomend revving the lucas too hard past 4500 anyway tbh as the turbo starts cutting out so no power after that where as bosch you can pull right through with enough fuel and dynamic advance.
youd be surprised how cheap you can pick a bosch up if you look in the right place

This will still obviously apply to a Bosch as well..
Unless you have the air there (obviously dependent on Turbo etc.), it's gonna be damn right shit in my opinion...
Not saying, it's not worth getting the Bosch, just saying, unless you have the right turbo, IMO it's pretty useless revvin' to 6k etc (depending on your turbo setup)

Well when the bosch is gov modded it will boost past 4500 even with a T2 i could hit about 5500 5700 on full boost
Basically you can getr a lucas to rev past 4500 but pointless as you run out of turbo past that, what turbo you running with your lucas? what other mods have you done, filter exhaust etc?

I'm sure you probably could. But I'd say it was pretty pointless in going to 5.7k on a T2, as I imagine you'll be way passed your peak torque & hp at that point. When I had a T2 a while ago, I found you didn't really need to rev it hard as when ever you changed up a gear you'd be back on boost anyway and on torque once more...
Just my opinion...

There's no point in revving very hard on a small, standard turbo as it will be way beyond its efficient working speed... Blowing hot air and raping the bearings. Much more so if you're boosting stupid amounts / dewastegated.

Thought I should clarify something, diesels are governed which regulate their speed. So, what you're experiencing is the gov cutting in and reducing the fueling. I have no experience with Lucas pumps, but I imagine the gov can be modified to increase the threshold it starts cutting in, in the rev range.
On a Bosch, the main gov spring is typically shimmed with washers. This means you can get an un interrupted supply of fuel through the rev range and beyond. Best free mod you can do. And is WELL worth doing, even on a Bogo standard dturb.

Np. There are a few different cars that use the xud9, google it for an exhaustive list. Stay clear of anything with electrical advance mechanisms- 406, late xantias.
With re to upgrades, the sheep thing to do on here atm is the td04l from an impreza. It's actually quite a nice setup, cheap and plentiful and is a great compromise. However, jumping on the bandwagons dull! Do something different if you cba. Maybe jump on the garret GT series wagon before it starts to fill? :p
