Depends on your spec my friend, my tte420 is already been at 460hp, and we are still playing with the fuelling. :happy2:

normal tesco 99 mate, its all about the build not just turbo limiting numbers. :happy2:
Is that pump fuel or race fuel?

Have you got a build thread or details?

No unfortunately not sorry, i tend to keep myself to myself about my car, and enjoy the element of surprise at track days etc. I did a build thread many years ago and had my old mk2 golf in PVW and even that was just a ball ache.

Fair enough.

Yep. Been there, done that. ATP is cheap Chinese crap sold from America. One of their VR6 turbo manifolds warped on me. Had to modify it and then get it skimmed. Waste of time and money.
I'd only stick to top quality brands like Loba imo. Buy cheap, buy twice.

That's what I thought - there's no info on who makes them and getting in contact with them has been useless.
The Loba 4xx and tte is a lot of money so I'm weighing up whether I stick with my K04 or upgrade and whether the gains are significant enough to justify around a £1500 spend - thoughts?

I haven't dabbled with TFSI turbo upgrades yet. Turboing old VWs like VR6s is more my thing, but I reckon the TTE420 will give good results and being an OEM+ upgrade, it will bolt up nicely and be reliable. If you want 500+ you could look at something like a GTX3071R which will hit hard up top and not be too laggy. It will need some custom work though.
Thing is though, those ball bearing Garretts can be gearbox breakers. Not so much in FWD applications as a lot of the excess power spins away harmlessly, but in 4WD applications, the drivetrain gets a hammering as the power can't go anywhere. Something usually breaks in the end. 3rd/4th gear shaft likes to spread apart when pushing big torque because the bearing carriers in the gearbox's end case are weak, and then gear teeth strip off. It happens gradually though, just a lot quicker when pushing 400lbft+ torque.
When I was turboing my VR6, I kept the torque within the range of what the gearbox could handle, but then again it was a daily so reliability was important!
AJP:
It's a very good point this, Pudding.
I'm nowhere near big turbo levels, but as you know I now need an uprated clutch as a result of squeezing more boost out of my little k03. And it got me thinking - what's the next weak link in the chain for me? Being a BWA it'd be rods. But then what? Will I really wake up one day and think "I'm happy with xxxbhp, no more power"? Hmmm.
We can keep uprating parts to cope as we go for more and more power, but as we do that it only makes another component the new weak link, rather than eventually getting to the point where the whole drivetrain and engine is bulletproof. And it comes to a point where driveshafts are failing, or boxes, like you say.
It's hard to know where to draw the line, and when to realise things are getting silly. I think I'll end up sticking to my long term plan of a k03 hybrid at a modest 320ish bhp. Keep the k03 response, stay within the limits of a usable uprated clutch, and hopefully not stress the rods too much.
But anyway, good post mate
pudding:
I'd say your plan won't stretch the clutch or engine too far. I don't think you will have problems with the rods either tbh as you won't be trying to get mega revs from it but you could stick some ARP rod bolts in. It's usually the bolts that let go before the rods do! I've only ever seen rods bend from excessive boost or detonation.
It's pretty much the CVs and then the gearbox which are the next weak links after the clutch. The gears themselves are very strong but it's the casing which isn't, but only if you push things too far :smiley:
My ED30 is around 320hp and it's frankly ridiculous in the wet and cold :grin: I've destroyed my F1s pretty quickly. I don't think many tyres other than racing slicks will put the power down, but they will put a lot more stress back into the gearbox!
bluo:
Guys what injectors are required to run the TTE420? I'm currently running S3 with my K04.
Do I need to upgrade the intank fuel pump?
