TF51 VRS - R Tech/BBT Hybrid K03 330/400

You have to agree though that there's only one way of finding out, proving a theory (whether right or wrong) and actually seeing what happens.
Yes it needs to be cheaper, but surely it's all part of the fun.

I can see it being down on power than a k04 but power isnt everything and engine response js what I like. I would presume this will spool quicker than the k04 so in theory for road driving should make for a quicker car and more responsive car.

[john a]

That's my initial thought in comparison the the K04 powered car I have driven although it's too wet to really exploit the low gears.

Add to that the linear delivery and the linear throttle and it's joyous. That's the best word I can use to describe it now.

i guess there's only one way to find out how it compares to a K04 car John....

FIGHT!!



Been to Nottingham and back this morning, about 100 miles all in. Christ it's fast and so, so smooth and tractable. Yes you can't give it full hammer in 1st and 2nd as there's just not enough traction in the wet and actually, it's capable of spinning the wheels in 3rd at 60mph too! With the linear throttle you just feed more and more power in and the car just wants to go and go and go.

The man's a bloody genius, there's no other word for it!

[Hurdy]

Excellent results John.

Graph shows just how immediate the delivery must be.

[john a]

It certainly is John.

If you look at the graph there is a very small area where the APR map had a small advantage in terms of spool but negligible to be honest.

That's also producing peak power at 1 bar - the stronger actuator ought to hold boost towards the redline and as a result should see approx 20 bhp extra. Nick seems to think it's flowing well, which is probably half the battle, and apparently nearly runs off the clock in 5th on the dyno!

Excellent results and in would be very interested in the price if this turbo as I'm currently getting my car ready for k04 but this may be a option

[john a]

On the Beach Buggy Turbo site, these are £650 + £75 for a 15PSI uprated actuator.
Yes, you're getting well into K04 money but I suppose the advantage is that it's almost a like for like swap - you don't have to fit all of the extra pipework, relocate the DV, etc and there is some comfort in that you're essentially getting a fully rebuilt hybrid K03 rather than a potential unknown quantity of a second hand K04.
With a stock actuator it's down on power vs a potential 360bhp out of a stage 2 K04, however if you follow R Tech's Facebook feed then you'll have seen the stage 2 S3 on there today that made 344 bhp and 358 lb ft. With the uprated actuator, in theory the hybrid K03 should give another 20bhp - that's 340 bhp and more torque than the K04 powered car.

By no means a conclusion but the points for me are:

• If you're just interested in numbers, get a K04 and go Stage 2 or 3 or whatever terms the various tuners give to their own products and stages of tune.
• This is still a development tune, I guess the maximum it's capable of is probably around the 340 bhp mark but with bloody lovely power and torque curves
• After everything else, it's such a bloody nice car to drive. Massively fast, recently described as terrifying (by a passenger, so it was either me or the car, and he's had some quick cars)
• At the end of the day, it's fun and isn't that what it's all about?

any more on this?  sounds exactly what I need 

[john a]

What to add really?! It's still going well, I can squeeze 32mpg out of it if I resist temptation and light up the front wheels in the first 4 gears if I don't.
It doesn't need any of the additional pipework fitting for a K04 conversion as it essentially works as a straight swap for a K03 turbo. I'm guessing you're not in the midlands but if you are, I'll take you for a spin if it helps you decide what to do.

[Leigh200sx]

I wish I was closer to the midlands so you could take me out in it, I've recently bought a mk5 gttdi and my initial intention was to go k04 route, but the more I think about it the more I'm swayed by the drivability of this option, it's like I have commented on Facebook it's not the pub figure I want, it's more the way it's gets there

[xjay1337]

I spoke to Alex @ AKS about this. following seeing the results on Nikis FB feed. So this is definitely on my list.
Definitely to me worth the money. I don't really want more than 310bhp (and wouldn't want to run much more than that on my AXX anyway...) but more than that, as Jon says - you get the piece of mind of a new turbo from a decent manufacturer..

[john a]

A distinct lack of pictures in this thread (sorry folks, I iz well busy gettin' an educayshun and that).

Turbo V2 was put on at the back end of 2014 and ran 330 bhp and 400 lb ft at (I think) 1.5 bar peak, tapering off quite quickly. I know Niki wants some more time with the car and I believe he is confident it will run close to K04 numbers. If you check out Andy Worthington's Mk5, his BBT K03 hybrid is about 360 bhp and 375 lb ft on stock injectors.

Here's a full spec if anybody is interested:

Fast bits

K03 Hybrid from Beach Buggy Turbo
R Tech magic software
RS4 FPRV
S3 Injectors
THS intercooler
BCS TBE with 200 cell cat
Revo intake and R Tech heat shield
Autotech HPFP internals

330 bhp, 400 lb ft

Handling and stopping bits

H&R Monotubes
H&R 28/22 mm ARBs
Superpro Anti lift kit
Dave B NQSBBK (front)
8P S3 310 mm upgrade (in a fetching shade of Porsche GT3 Lava Orange)
Superpro Dogbone mount insert thing

Wheels and tyres

18 x 8 Speedline Marmoras with 225/40/18 PSS/PS3 front/rear
18 x 8 Neuspeed RSe07s (one to be replaced)
18 x 7.5 Stock Octavia vRS Zeniths with 225/40/18 Nokia WR A3 winters
I also have a set of 225/40/18 Nankang NS2-R for track to see if they are any good or not.

Fancy looking bits

Skoda Columbus RNS510 with DAB
Sticky-on DAB aerial (front windscreen)
Kufatec Fiscon Bluetooth kit
Facelift taillights
Heko wind deflector things
Some LED interior lights my mam bought me for Christmas
Stupid, badly fitted, scabby lacquered carbon mirror caps
Daft tinted windows to stop various scrotes and scumbags looking inside if I have guitars and stuff in the car
Daft TF51 VRS number plate

Fancy factory bits

Jumbo armrest box (with chiller for your pop/small can of continental lager)
4x leccy windows
Auto lights/wipers/dimming mirror
Xenons
Maxidot (that's a red Highline to you Mk5 lot)
Cruise control


That's it, it's just a car really isn't it. I have some bits to do which may renew my interest in it. It's still fast, it's still fun, it's still incredibly practical, it's done 103/4/5/6/7/8*k miles (*one of those numbers, I can't remember. I'm inclined to say 105,000ish - it was only serviced in October or November and it can't have done more than a couple of thousand since) and if I had to sell it tomorrow, I don't know what I would get for the same money, that did the same job.

Here's a picture of what it looks like currently.
