Further Positive Engine Developments for FPR
Foggy PETRONAS Racing riders Troy Corser and Chris Walker have praised the latest developments to the PETRONAS FP1 power unit, tested at the Circuit de Nevers in Magny-Cours, France over the past two days.
Dry and sunny conditions throughout today enabled the team to capitalise on the initial adjustments and progress made yesterday evening with the latest engine specification and new STM clutch.
Both riders worked relatively trouble free through the comprehensive testing programme completing more than fifty laps each today, with consistent and competitive lap times adding to the day's many positive outcomes.
The PETRONAS engine development team's successful revised engine specification, containing cam train revisions which allow the engine to rev another 1000rpm, produce more peak power and provide greater gearing options, means this latest stage of engine development will be used at the next round of the World Superbike Championship in Assen next week.
Troy said, "We've had two good days and tested quite a few things including the latest revisions to the engine and also clutch settings. The slipper clutch feels much more consistent but there is still a little room for improvement which we can work on at Assen.
"I've tested a whole range of tyre constructions just to assess them with the different clutch settings, and resulting in nothing out of the ordinary which is good. Given this is the first time we've been here on Pirelli's I'm happy with my lap times which have been consistently in the 1:43s and overall feel we've had a very productive test."
Chris commented, "Other than a small trip into the gravel at lunch time today when I lost the front end on one of the slow corners, it's been a fruitful couple of days. It's been very beneficial to have time to get used to the new power characteristics of the revised engine and get back up to speed ready for Assen, which is a fast track when you've been riding every week let alone when you've had a month off! The latest engine spec feels very lively and revs really hard which is good.
"I've also had the chance to concentrate on getting a good setting for the fuel mapping and ignition curve in readiness for Assen. This is the first time I've ridden here on the PETRONAS FP1 so to end up with lap times only three tenths off Troy I'm really chuffed, especially knowing how well he went here at the test last year."
