Keen to keep up with the times VW Heritage have started working on more modern Volkswagen vehicles too, and as well as offering Revo performance software we can also supply and fit Milltek exhaust systems to make your newer Dub go even better. We spent an afternoon doing some testing, exploring the differences in both software and hardware upgrades on a 2005 Mk5 Golf GTI.
Benjamin, our Technical Specialist, owns the Golf in question, and was happy for us to use it as a guinea pig. Already knowing the gains the Revo performance software offered, we were keen to test the benefits of the TFSI intake from Revo.
This late 2005 Mk5 Golf GTi 2.0 litre TFSI, equipped with 6-speed manual ‘box, started life with 197bhp. Having clocked up nearly 163,000 miles, this example was perfect for a real world test, a car that the majority of us could have on our driveways, not a brand new, zero mile car like those often used to provide us with ‘best case scenario‘ performance figures.
The car was almost standard, the only modification being a Turbo Back 3in Milltek ‘Race System’ and some higher octane Shell V-Power fuel.
Making the trip to Devil Developments in Littlehampton, the car was put on the dyno for the fun to begin. Starting with the car in stock mode, a figure of 213bhp was achieved, showing the benefits of a free flowing exhaust, even on the smaller K03 turbo’d cars. We loaded on the Stage 2 file and once set up, 258bhp was achieved. A 45bhp increase from software alone.
After removing the stock intake and replacing it with the Revo 2.0TFSI intake, we then dyno’d the car again in both stock mode and Stage 2.
The engine as standard and then the engine with the Revo intake added.
On the stock setup, a 10bhp gain from the intake seemed impressive enough, but the difference at Stage 2 was greater again, leading to a peak figure of 277.6bhp, 20bhp higher than the standard intake. Peak torque figures were also up by 25 and 35lb ft from stock and Stage 2 respectively.
Below are the results from the dyno for the stock software pre and post intake.
Below are the results from the dyno for the Stage 2 software pre and post intake.
|Peak BHP||Peak Torque|
|Stock (+ Intake)||223||270|
|Stage 2 (+ Intake)||278||350|
I am sure you will agree that the above figures are impressive. It certainly made a huge difference to the way the car performed. Peak figures are great but the performance gains throughout the engines rev range is what you need on the road for better drivability.
Over 50% of our customers drive Diesel engine vehicles, which means it’s not just the performance petrol engine cars that can be improved with Revo products.
