Yesterday, KWE had a visit from a customer who brought his beautifully restored Series 3 Jaguar E type for us to look over. It recently had a brand new late 6 litre fuel injected engine, with AJ6 Engineering power and torque enhancements installed by another company.
Unfortunately, the engine was not running smoothly at all, suffering from throttle lag among other things that were affecting its performance and efficiency. Luckily for him, AJ6 Engineering pointed him in the direction of KWE, who was able to rectify the issues with their specialist knowledge of the V12 engine.
After diagnosing the problem, KWE was able to fix the throttle lag issue within a couple of hours, resulting in a much smoother and responsive drive, while also significantly reducing the emissions at the same time, with some smart adjustments to the ECU.
When the E-type came in to the KWE workshop, the emissions test was reading 7.9% CO, just before leaving it was down to 0.3% CO, which is an incredible reading for a car running a 6 litre V12 engine!
We asked the proud owner to give us a few words on his marvellous machine:
“My V12 Roadster is the 4th E-type I have owned, and by far the best (and that includes a restored and upgraded early Series 1 3.8). When this Series 3 was restored it was re-built with a new factory fresh fuel injected 6.0 litre V12 which included upgrades from Aj6 Engineering in the form of their Torque Plus kit and larger throttle bodies to accompany their TT exhaust system. In all, giving a significant increase in power and torque. Not to mention a V12 that sounds wonderful! With all the suspension upgraded to include adjustable dampers and neoprene bushes, upgraded XJS brakes, an XJS 2.88 LSD diff it makes this 1974 car feel appropriately up-dated in every possible department. Just a magnificent car to drive and to own.“
Another happy Jaguar owner driving off in his much smoother running V12 E-type.
If you are experiencing any issues with your V12 engine, arrange a booking with KWE.
