|Peugeot 306 GTi-6 & Rallye owners add over 25 bhp with Cat Cams|
Following on from the results below, Pug1off re-tested the 4903106 profile on another car just to check the results.
This time the engine already had a 'Piper' Inlet only camshaft and made 178bhp on RS Tuning's rolling road.
After the initial test the cams were replaced with a pair of 4903106 Catcams and remapped to suit.
The final results are 193bhp with gains from 2000rpm over the previous setup!
The owner reports this has transformed the way the car drives.
With 167 bhp from the factory and an entertaining, capable chassis, the Peugeot 306 GTi-6 and
Rallye models have acquired something of a cult status as great all round fast road and trackday hot hatches.
But even the best can be improved upon, which is where leading high performance valvetrain
specialist Cat Cams NV comes in, with its 4903106 profiles. A direct replacement for the
comparatively mild standard factory XU10J4RS cams, the full technical specification of the
Cat Cams 4903106 profiles is:-
267 / 259°
228 / 224°
10.95 / 10.40mm

Back to back dyno testing on Northampton Motorsport’s dyno by Peugeot specialist Pug1off has
shown (when used in conjunction with a suitable ECU remap) that the Cat Cams 4903106 profiles
produce exceptional power gains, in this case 26 bhp.
Crucially, both power and torque are improved throughout the rev range, with a 17 lb.ft peak torque
increase and 10-12 lb.ft extra at 4500 rpm, making this an ideal fast road upgrade.
During testing the peak power increased to 181 bhp at 7500 rpm, with over 175 bhp available from 6100 – 8000 rpm.
(NOTE: The stock car seemed down on power, producing 155 bhp but this could be as a result of the 145,000 mileage.)
As a result of the Cat Cams / Pug1off ECU remap package, peak torque increased to 150 lb.ft on the high mileage test car.
Available now from Cat Cams stockists, the 4903106 profiles for the XU10J4RS engine used in the
Peugeot 306 GTi-6 and Rallye are available now, priced at £486.00 including VAT.
