9mm vs 11mm pumps

[Dave]

No one here has issues with fuel... nor does anyone take their cars above 5.5...

i did once then shat a brick and changed gear haha

[Dave]

People should stop being girls about that :p

[anto]

My mate made 161.2bhp and 238lbs on a 9mm just turned up and t25 at rs tuning

I ran 166bhp iirc and 245 pounds iirc on a standard 9mm turned up and bigger turbo....

I may open a can of worms here.........I done one very, very simple 'bolt on' mod and although never dyno'd it again it pulled ok 6 after (4.5-5 before) and I could make smoke again, easily a 15-20hp bolt on......if youve the air and exhaust flow......heres how it went and sounded after though it was winded down abit before these vids for smoke reasons:

You're a bad man Connor teasing people like that lol

If you dont want to fit an 11mm pump then the mod con did will allow the 9mm to flow plenty more fuel, and probably retain more of the revability of the 9mm. Can also be done with pump on the car, altough you would want to be doing advance mod and gov at the same time so pump would be off anyway.

[Joe]

con, did you run defilter? and we al know this bolt on mod was fuel magnets.

was it??????

[n0v0s]

iirc, he got two magnets from broken FLI subs..

[strictly_perv]

Seriously though, what was this 'mod' Con has done?

Same goes, Having a look of the forums now, but not really any idea what to search/look for.

[Poodle]

Dave and anto have given good hints and ed's told where to look, i've found stuff in an evening with less info than that, pull your fingers out!

[Chris]

I've been looking all day, not really seen any info about bolt on stuff though.

Then again I've only been looking on vwdiesel.net atm and google.

[Dave]

Take a pump apart, theres always gonna be bolt on stuff from almost every pump, like better things from one pump and better things from another, other camplates, plungers, cradles, LDA's to list a few... undertsanding what these do and why will help you pick a better one if you ever come accross another pump

Been reading plenty regarding pump mods, changes etc today.
Just to clear up terms.
Cradle - gov cradle?
Plunger - as in what most refer to as head size so 9, 10, 11mm etc?


Just a quick one are the leaver sets all a fixed length and require modification to increase travel, or do different pumps have different lengths?

Cradle - Yes this is the cradle which the governor sits in. It is possible to change out the stock Bosch cradle for one from another pump, which gives you more control.

Plunger - This is the cylindrical rod which moves inside the pump head. This pushes fuel through the head and relates to it's diameter, so yes - 9,10,11mm etc. The mechanical stroke of the plunger is determined by the camplate which is further inside the pump.

[Chris]

Thought as much, just making sure I'm thinking of the right parts for the terms being used.
Been getting my head round how the pump actually works over the last couple of days.

No PM for me Toby? :mrgreen:

& me, want to find out wtf everyone is talking about!

[4WayDiablo]

Might as well just post it on here public then Toby haha

I'd rather not, this is still a public forum and I will only advise/help people who have proven that they live for the 306

Or people who are called Phil

Haha good plan! Batman!

[Dave]

Lol why state that you've sent someone a pm.....

I dont understand all this chasing for pump modifications anyway, they fuel really well as they are with a govmod, and rev like buggery... no one has a car that maxxes rpm/fuel out...

Darren lobby did.
You must be forgetting that each one of ours is just as powerful as his though

[Dave]

Darren had silly amount of airflow, of which the pump couldnt keep up. What do you mean each one is as powerful?

[4WayDiablo]

Never mind lol was saying we all have exact spec as Darren so need to know these super secret mods lolololol
But writing g things out never conveys the way it is intended to be said lol

[Dave]

I dont get it though, they're not super secret mods, they're just things that can improve overall fuel output? Taking the pump apart you'll see that they are all simple, but for a daily setup like 90% of people, they are totally unnecessary, and would just make you smoke a hell of alot more because most peoples cars the pumps are not limiting, even then just bolting on a bigger head makes it run more fuel.

[darrenjlobb]

I can quite assure you that your pump is not the same as any pump I've ran for months lol....your pump literallly just has a gov mod done....

[Connor]

Why does this feel like the way tb is with mapping? :/ People keep saying that the information is freely available and is all over other forums, then why not make it all over our forum? I really dont get the secrecy, yes I appreciate that some of you guys have spent loads of time reading various forums and actually stripping pumps back ect. but most people wont have the capacity to strip a pump :/ things wont move forward if everyone keeps things to themselves or within a handful of people

[Poodle]

Phil was joking guys, the giveaway was the "lololololol", for future reference.

Just saying people want to know for the sake of knowing and because they'd like to think that, while they're not quite on your level, maybe they're not far behind. Whereas the reality is that anyone who wants/needs to know enough will have already found out for themselves, everyone else is just nosey. Like me! Lol.
