OcUK Rolling Road Day 20 @ Ti Motorsport (Stoke) - Saturday 29th October 2016

I liked the place and agree with your comments. Ramp up seemed slow and deathly, airflow seemed awful.

I stood in the dyno cell a good few times and it was really warm. I've never felt a dyno cell that warm even on hot days.

I would go back when they have more experience and better airflow.

I am gonna pickup the BMW today/tomorrow I might ask about re-running it with bonnet up, but as it feels so savage on the road I probably will not bother. Just seems like some other cars the M3 is very sensitive to heat, whereas the Mustangs really did not seem to care, I was to be blunt a little impressed with my 472BHP, I was expecting in the region of 455-460BHP maximum and the completely stock car made great numbers as well with 415BHP, though its torque figure was considerably down on stock, but the owner did admit to only running the car on cheap super market fuel probably means the car was running 21-22 degrees timing WOT, whereas on good fuel the ECU will advance to 23-24 degrees which helps with torque for sure in mid-range.

I'd rerun if I were you, just to compare!

I was planning to send them some feedback on the day. Maybe it's a bit less patronising if you talk to them about their cooling etc. face to face?
 
I won't dispute they did alright, glad they were aware of the ramp up issues. Watching back some of the videos the pulls were far too long. Improved airflow would negate the bad ramping up though.

Cooling wise, regardless of what they have, it was simply too warm in there. The air was stagnant too. They need to work on it and I hope they do :)

Fudged figures wise, well you can do a number of tricks on any dyno! Moving the IAT sensor can have a huge effect for example (most respectable places leave it on the wall mind you!)

I am not disputing my own figures btw. I-mode running 300bhp on the nose is exactly what I expected (hence I ran 13.1 with it in said mode). The 2 other runs in S mode pulled a crap load of timing and felt just how my car felt at Shakey (hence running slower than I-mode) and so I will be revisiting my mapper in due time.

Glad you managed to speak to them though.
