So took the trip up to Alex yesterday to have the Group N timing carried out and a few other parts fitted. And then onto Engine Dynamics for mapping.
@Stefan. came along too as he was having Alex carry out a belts change on his Trophy.
Alex working his magic on the timing...
Then onto fitting the new Pure Motorsport exhaust system, along with the stainless Pro-AM rear hanger mounts.
When comparing the Pro-AM mounts with the old ones, you can see they are a tad shallower than original ones (10mm to be precise) as shown in this photo. This essentially means the exhaust sits 10mm higher/closer to the bumper cut outs. This was a nice little bonus actually as whilst the Pure system is a nice bit of kit, I’ve always noticed they sit a bit low for my liking and you get a bit of a gap between the tip and bumper cut outs. Not the case when mated to these Pro-AM mounts! Looking really nice underneath here.
Then it went to Andy at Engine Dynamics for mapping. Obligatory photo outside...
The end result...
Very happy with the figures. Have gained almost 30lb/ft in places at the lower end. Torque gain is very noticeable on the road, pickup is so much better between 3k-4K rpm. Peak torque is also achieved earlier in the rev range than the standard map too. And it made just shy of 190hp at top end as well.

After the mapping, there were just a few small jobs to finish, namely:
- Adjust/align exhaust system after it had been initially offered up
- Fit powdercoated rear caliper carriers
- Remove 1 x 10mm spacer from each side at the rear
- Fit new engine mount bolts
- Fill PMS shifter linkage with lead shot
Because I was running 20mm stub axle spacers at the rear, I was getting a small amount of rubbing at the height the car was at. The front was also catching on lock. With 10mm removed from each side at the rear, and a slight modification to the front bumper brackets, all rubbing is now cured and is much nicer to drive! Still sits and looks really good.
PMS shifter is now much quieter after being filled with lead shot, a great mod! Not completely silent, but much more tolerable.
Do love how clean the engine bay is on this...
And finally, I’ve had to order another pair of exhaust trims from K-Tec as mine are both melted. The left hand side was melted from the old exhaust which wasn’t aligned too well. And then the right hand one was my fault on the way back from mapping. I was flat out for a significant period of time chasing down an Exige S on the journey back to Alex’s from Engine Dynamics. Given the new exhaust wasn’t fully aligned when it was fitted prior to mapping (as I wanted to drive the car first to see let it move around a bit and see where it would rest/settle before final tweaking), it must have been sitting on the trim when I was wide open on the throttle! 😅 gets expensive at almost £80 a pair for replacements (the ones on the car now were new a few months ago) 😅 never mind!
It sits fine now it has been tweaked, doesn’t touch at all, so new trims will be safe from melting!
