Ben - lots of 'ifs' coming up, but if you decided to go the uprated fuel pump route and if you decided APR is the [pricey] way to go, I'm looking for one as well so we could potentially get a discount somewhere.

Cheapest I've found so far is using the rebuild option, from the US, at around £420. I do have a spare pump though, which makes this a viable option - not so easy if your car will be down for a while. Also might get stung for customs tax on the way back in.

If you have a spare pump look into Star performance and AMDTechnik as they wil let you post the spare pump to them, they will install the internals and then send it back to you for the same price.

I replaced my cam followerrer to be on the safe side when i did mine though. just for piece of mind.

Sy:thumbup:

Revo stage 1 Octy Mk2 Vrs

whats your additional mods or is that just remap.

those figures seem a bit higher than the other stage 1 revos graphs i have seen. plus your torque figures are in the realms of the top stage 2+ cars with all the supporting mods.

I want to get mine put on a dyno dynamics roller as they always seem to be more consistant and accurate

The autotech is very good. I bought mine second hand off Steve( Makefish) for a £100:thumbup:. I have done approx 30k on it now and it seems quite easy on the follower too.

I'll look into that Si - I'd ruled out KMD and Autotech simply because I don't trust myself to mess with such a vital component, didn't realise there were places that actually did the fitting (other than Autotech themselves, but they're in the US)

You can't mess it up, it's a very simple pump, anyone with a bit of knowledge can do it.

The chap that owns that car has Milltek cat-back exhaust,autotech fuel pump,plus Evoms.

mine was done by AMD essex because i didnt have a deep enough 18mm socket, and to be fair i wanted to see the results on the RR after.

There are a rafty of companies that will do it for you.A Try Backdraft Motorsport as well. these do their own brand of fuel pump internals which they use in all of their race cars, so must ok. Im sure if you send your pump to them they would put their uprated internals in it for you.

@micky your sig is out of date mate:P

more of a stage 2/stage 2+ setup really which might explain the high results i guess

@timmyboy

have a lookat this How to change Fuel Pump Cam Follower on 2.0 TFSi

this is the how to replace your cam follower on the inside of your fuel pump. which have been known to wear down so its wise to buy new when you change your pump. it also shows you how to take off your old pump and how to put it back in.

one thing to take note of when taking off your pump.

once the pump is off do not open the drivers door as it will try to prime the fuel pump which incidently will not be on so you'll spray fuel every where.

other than that. its an easy job

I disconnect the battery to prevent it from priming however this could create a spark risk. It's your own choice in doing this.

Changing the internals isn't hard, just take your time.

Thanks Harry and Si for the tips - will mull my options over for a while, it's a fair bit of cash

Or you could take the fuel pump fuse out.

I have a set of Autotech internals but I don't know whether to bother fitting them after the stage one remap or just sell em hmm.

I'm really not sold on the pump/internals thing I'm afraid. As I've written earlier in the thread, I'd have to run more boost to utilise it to it's potential and I don't want to do that. I think my car's running pretty good power without it to be honest, especially compared to some of the cars that are running the pump.

Not worth another £300-£750 IMO. Not on my own car at least.

I've heard they're not compatible with black cars.

You can sell it to me and I'll get a re-spray

Seriously though, my limited knowledge tells me you won't see any benefit with a stage 1 map unless you can get hold of one that would specifically make use of the extra fueling available.

Give me a shout if you decide to sell at any point.

you'd be able to do it on a stage 1 car and see benefits if they mapo it aggreesively, but then you will be increasing your exhaust gas temps with the std exhaust and cat. hence why it is stage 2+ and not 1+.

At the end of the day if the butt dyno is happy thats all that matters really.

but i want you to do it so i can see you results,

Ha ha will do.

Surely logging the AFR would tell you if the cars needed this pump anywhere in the rev range?

a good stage 1 or 2 map should not need the fuel pump though, as they can adjust it tp stay on the safe side of fuel cut and fuel starvation.

but if you fit the pump it is possible to increase the fueling(hence the reason why an intake is highly reccomended at this stage) and boost,

more boost, fuel and air = more out of the engine. but at that stage you wil need an intercooler a the inlet temps fly up quickly as i have found out myself.

I thought that's what we were going to use your car for

might go for a cat back and intercooler first though so we can go the hole hog on her.

You definitely need the exhaust as the standard system is very restrictive up the top end.. and if you want to push the boost then yes, an intercooler will help a lot.

Having seen a Revo Stage 1 car (only other addition being a cat-back exhaust Milltek/Blueflame, I can't remember) making substantial gains with just the Autotech pump internals, I find a lot of this discussion about it being "pointless" just plain wrong (and misleading to potential purchasers!). People may find it difficult to justify the expense etc, but the gains are definitely there to be had, even on a stage 1 car! I wouldn't even be suprised if you popped the internals on a standard car and saw gains either.

I got mine cheap so i stuck it in. As these engines are prone to fuel cuts when mapped highly i think even if the car doesn't have a fuel cut it's still piece of mind against the risk of the car at least running lean.

When i first had my car it was mapped aggressively on standard engine no mods. With each mod i fitted i noticed everytime the engine pulled more and the pump definately made a difference, definately had a nicer low down pull. To put in prospective the map with no mods the 60-100 was 7 secs. After fitting the miltek and pump the 50-100 was 7 secs!

Going back to the 2nd or 3rd page of this thread, I was questioning if a true Stage 1 can produce in excess of 260 bhp as shown on the graphs back there. As I said then, anyone coming on to the forum talking about 250 bhp because that is what the mapping company promotes gets slapped down.

Figures/curves showing 250+ bhp on Stage I have generally included the fuel pump mod and an induction kit as a bare minimum.

...and the map always seems to be a Revo making me conclude that it is an aggressive 'Stage 1' that can utilise the HPFP.

However, I put 'Stage 1' in inverted commas because, to my understanding, a Stage 1 that needs additional hardware is not a Stage 1 by definition :confused:

I'm only going on what i have seen. I know a stage 1 Revo car that gave the same result on the same RR before and after the pump.
