mk3 20v more power please

[benvictors]

You dont need to change the fuel pump unless you are pushing for more than 300bhp, even up to 400bhp they have been known to be ok.
K03s at 260bhp?!? Wow, I bet thAt turbo lasts about a 1000 miles lol

[golfyste]

Fuel pumps have known to go below 300bhp and depending on the mileage of the engine te pump could be on its way put and the last thig you want is it leaning out as knackering the engine.

I dunno if you have been keeping track of the recent developments over the last 12 moths but they can hit 260 if the build is done properly
But obviously that is pushing limits so 250 is a better target 

[benvictors]

Not disputing the figure, just saying you are seriously ringing its neck at that sort of power 

[golfyste]

260 is literally the limit of the turbo but its normally the rest of the build that's the problem which means you can't run it too its limit 

As long as its mapped well and has WMI etc it should last a long time at 250

thanks guys,
im thinking id b happy with 235bhp if thats possible with a silicone tip and a ko3s thats pretty much all ill need extra and to reach 250bhp seems a lot more expence like i said i just didnt want the turbo to be at its limit or as ben puts it ringing its neck im of the thinking that 235bhp with a happy engine is better and will give me more reliability than a maxed out turbo on its limits. thankyou for the welth of kn owledge all really appriciated

260 from a ko3 aint gonna happen unless u visit a certain rolling road... (do they even alow enough air to flow this much)

you will be doing well if you map to 260 on a KO4!!!

fuel pump is fine on the GTI - mine is currently at 350 bhp on the GTI pump  (it is been changed tho when the car goes for remapping - im still only on 10 psi boost at the mo

[golfyste]

R-tech have recently been pushin the limits of the k03 platform and they also have good reliable rollers
They'd aged to push the standard k03s to 260 and littco made a hybrid and got them to test it and made 300 bhp and has made a new hybrid which r-tech are currently testing which looks like it may be finishing somewhere around 330 (hopefully)

I did say about the pump I would change it just to be safe not that you have to as the last thing you want is the engine to recieve less fuel then it wants!

Standard k04 limits with a relentless manifold and other mods is around 300-310bhp (Toby on here hit 304)
And the k04 hybrid has managed to hit 354bhp max but has currently been detained as it needed a bit more fettling an is used on a trackcar so they wanted to be safe with the temps.

Wouldn't believe all the r tech hype all the time if I was you

Didnt somebody on this site have a mk4 that was a claimed power only for it to be nowhere near that power when it was on a dyno dynamics rollers 

A remap and a Ko3s is gonna be 230 ish BHP I'd say

[golfyste]

Well they hides to get around 230 on their rollers just like everyone else untill their recent breakthroughs where now thy are gettin 250+ on te same rollers

There are also many cases of their rollers wing proven accurate again other reliable rollers compared o the one case you are talking about with a dyno dynamics set which iirc (not 100% sure) add a fixed percentage to the wheel power so in your case the fixed %. May have been "wrong"
I'm not sure but I follow r-tech/badger5 and others closly and have found that they seem like te more reliable tuners who know what thy are on about and give consistant reliable figures.

Just my 2cent
