Having been looking at a Mk7 GTI or R to replace my Mk5 R32, I've now switched to looking seriously into upgrading my existing car instead. Why have a bog standard hot hatch, when for less money I can have a custom?


TRD are close to where I live and I've been researching their supercharger options, based on an RUF kit. It looks like they've done half a dozen or so V6 supercharger conversions just in the last year, based on their Facebook page.

To quote from their e-mail:

Stage 1 takes 4 days to install, no engine modifications are needed but we recommend a Milltek cat back exhaust system and better front brake pads. The kit includes everything needed; belts, cold intake air filter system, silicone hoses, diverter valve, spark plugs, injectors, pulleys, poly engine mount, ecu upgrade, nuts and bolts. Cylinder head removal is not necessary on our kit, unlike other supercharger kits and turbo conversions. Because the charger itself generates no heat and being mounted on the gearbox, it does not suffer from heat soak, for example, if it was mounted to the head or block. The aircon system is still retained and not affected by the install. The kit is suitable for Manual or DSG configuration and fits left or right hand drive cars.

The supercharger is driven off the auxiliary belt and across the engine via an alloy propshaft under the intake manifold. There is no need for a separate, cooled oil supply as it has its own oil lubrication system. The high efficiency RSC compressor spools with a speed of about 36,000 rpm giving a boost pressure of 0.5bar and a performance increase of up to 100bhp. Stage 2/3 takes 7 days to complete, it comes with a water to air PWR charge cooler and additional charger modification up to 0.8bar, that increases the performance of the base engine up to 400bhp. Each installation has a custom engine map to match the setup, with a dyno run and printout. With over 80kits sold and tested throughout Europe, this system is a very reliable and adds the performance that the 3.2 engine lacks. We only install the supercharger conversion here in our workshop and not sold as a DIY kit. The supercharger has a 12month warrantee excluding rubber belts.

Stage 1 350bhp
Stage 2 375bhp
Stage 3 400bhp

I'm looking for reliability, subtlety and driveability as my main priorities. My R32 isn't used daily, but it is our only car - and I don't have a lot of time to try out different options (busy job).

I'd probably go for Stage 1 and add a Milltek backbox, brake pads and Bilstein B14s at the same time.

Any reasons not to go with this?

You'll never see 400bhp from a VF/RUF/Carlicious charger there all the same & about 15 years out of date!

Rotrex is the best option or a HGP/HPA turbo kit

Turbo kit for me was out the question because of the way the power comes in meaning clutches ect had to be played with... But as for the RUF vs Rotrex chargers why would you say the Rotrex is better? Is it because you can push it past 400? And have a little more headroom where with the RUF supercharger you are stuck at what it gives?

I haven't seen a 400bhp one yet, the most I've seen is 380 and that guy had cams too. Will be interesting to see what figures Lee's makes on the same dyno as a few others so it isn't biased. Look forward to going out in yours Lee

Tbh i went to something i was limited at.. (sounds silly) but if i put a turbo in ect and there was power to be had i would want it and spend everything i got to get it! lol So for me i'm happy with what i picked! But if i wanted headroom ect and was chasing big numbers i would of went Rotrex or even Turbo... but most likely turbo

Yeah no doubt Tej once its all done we should go dyno both our cars somewhere!

FI isn't worth doing for an extra 100bhp.......

Look out for a 2nd hand HPA/HGP turbo kit, proven results & bulletproof

Do you really want an alloy bar spinning at high speeds right at the front of the car? VF chargers or RUF/Carlicious are all the same, unreliable & oil seals fail on a regular basis never mind belt slippage

Im sure belt slippage is somewhat a problem of the past? As they changed the belt compound to stop that?

But the way i look at it is if it doesn't play ball and starts playing up i know i can take it back to where i got it! As for the bar spinning no i dont really mind that? Why is it a problem? My prop shaft spins that doesn't worry me.

How does a belt compound change aid belt slippage lol?

You can't touch your prop shaft & even at idle the bar will still be spinning at high RPM's, what about if you have an accident? Has the kit been tested to see what happens? Doubt it........

If someone wants to stick their hands onto a spinning bar i say let them carry on.. if your that dense in day to day life you deserve all you get imo. Its no different to sticking your hands onto a drive belt is it but that's not covered up?

As for the belt i have spoken to many people running the kit and they say that new belts sorted that and belt tension had to be set correctly.

I understand you used to run a Rotrex supercharger and loved it, i understand what its like i'm the same with computer parts one being i stay away from AMD stuff! But i dont see the RUF kit being that bad you just favour the Rotrex kit.

Interested to do this as well. Spoken to both TRD and Storm who can supercharge and both have quoted around £9000 for around 400hp (added pinch of salt)

My only concern is the reliability as i don't want to create a money pit.

Interested to hear all pros and cons

I must admit I nearly choked on my coffee when I saw £9k for 400hp.You could sell up and buy a lovely RS4 for that !! Storm were offering 400hp SC for £7.5k not long ago, plus an entry level 350hp Rotrex kit for around £5k. Not sure what the stated £9k includes though.

Gaz Jones is putting a turbo kit together for around £7k all in for 480hp. Although it may be for mk4, not sure.
