Hi all,
After suspecting that my 197 was quite down on power, I finally had the chance to have it on a dyno. Sadly, due to the spontaneity of my trip to the UK, I couldn't book with any of the major specialists as they all had long wait times, so went with "117 Speed" in Manchester, which booked me in for the day after my trip. They have a BAPro BPA-4R HP dyno, if it's of any relevance.
I had my spark plugs done just before, as I still had an occasional misfire (as previously mentioned in another post of mine) and it was the last thing on the list to change. I was quite stubborn to change the plugs as they were fairly new, being juuuust over a year old, but according to the owner of 117, they looked quite overdue.
I do have one of the plugs, so will try and post a picture later.
Anyway, I digress...the car made 140 HP to the wheels and 189.5 HP to the shaft - I assume this means input shaft/flywheel? - If we're assuming up to 15% drivetrain loss, wouldn't the flywheel power figure be closer to 160HP?
Dyno graph below:
If the shaft power figure is anything to go by, this would mean my car hasn't actually lost any significant power over the years and while being on low compression, which doesn't sound right at all. However, dyno man said she was (and to quote his words) "bang on!"...
What's the average WHP figure for a healthy example?
Any input appreciated.
Thanks in advance for putting up with my questions, once again
