Thanks chaps, great advice from all three of you

Creating the cleaner dyno comparison graph has really helped to identify the true horsepower and torque gains from Stage 2 to Stage 3 Monty.



What's super rewarding to see is, to some degree or another, there are genuine horsepower and torque gains literally everywhere.

1. While we're missing data from idle to 3,000rpm, Stage 3 Monty is definitely smoother and more flexible in this important drivability window, so I'd speculate the 10 lbs/ft advantage we can see at 3,000rpm is also present lower down

2. From 3,000rpm all the way out to 6,400rpm Stage 3 Monty not only hangs onto this torque advantage, he decisively builds on it so by 6,400rpm Stage 3 is now serving up an impressive 16 more lbs/ft of torque over Stage 2 Monty

3. During the same pull Stage 3 Monty is also delivering a meaningful horsepower increase, rising from 5hp more at 3,000rpm to a healthy +10hp at 6,400rpm

4. From 6,400rpm where Stage 3 Monty is not not only serving up 10 more horsepower and 16 lbs/ft more torque the gap between Stage 2 Monty gets even wider, by the time Stage 3 Monty reaches 7,000rpm he's making a whopping 33hp more than Stage 2 Monty. As you might imagine, because that additional 23hp is delivered over a very small 600rpm window the push it produces is noticeable

5. From 7,000rpm to 8,000rpm the horsepower difference surges rapidly from +33hp to a game changing 50hp horsepower more than Stage 2 Monty at peak. Not only does Stage 3 Monty hold onto his horsepower in this top end zone where Stage 2 Monty would have long since given up and gone home, the torque difference between the two states of tune is now also huge, at 7,300rpm Stage 3 Monty is serving up 45 lbs/ft more grunt than Stage 2 Monty!

In summary, it's clear to see there are good gains everywhere and where I can genuinely enjoy them, with 30 more lbs/ft of torque arriving 6,800rpm and 33 more horsepower at 7,000rpm, this is the sweet spot where during enthusiastic driving on the road I would be looking to select the next gear and then enjoy that additional push all over again.

On the track where more revs can be used safely, taking Stage 3 Monty further is a no-brainer, with an additional 45 lbs/ft of torque arriving at 7,300rpm and 50hp more horsepower at 8,000rpm than Stage 2 Monty could muster at the same engine speeds, because Stage Monty 3 Monty has held onto all the power he made 1,000rpm earlier, it's now definitely worth taking the engine to 8,000rpm and beyond.

With all this in mind, I think the only decent thing to do is go out and enjoy Stage 3 Monty in all this lovely weather, and before it becomes too hot.



Remember chaps, fast or slow it really doesn't matter.....

We all have a wonderful Morgan, so do take yours out today and enjoy it in the sun
