Don't think any of those work.

I've got video of your car and most the others. Taking a very very long time to upload mind..

Mx5 with more Vroom Vroom than Zoom zoom.
I like that.

:cool:

i'm so annoyed that i filmed this all in 720P so much fail, the movie maker+ youtube compression is also terrible, they look so much better out the camera.
 
Its sometimes better not to dyno things for that reason. :(

The important thing is what the butt dyno tells you. Not a number. :)

I was just being childish because of the amount of flak I used to get for even suggesting that a CTS was equal to, or faster than, an EP3 Type R.

Should get a proper re-map really, but I suspect a Bluefin will net you a noticeable difference. VAG TDI's map really well. Should get about 20HP and more importantly 50lb/ft.

I'd be interested to see just how much quicker the CTR is compared to my Mx5, considering I should lighter and only 26hp down.

I know just how much lighter if it wasn't for that obese BMW ;)
 
Opinion time then. Seems like the place has a nice facility but ultimately is a bit of an amateurish operation. Not keen on the dyno at all, was more like a torture test than a power measurement with that ultra slow ramp rate and poor airflow.
 
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.

So the EP3 pulled about 1HP less than my CTS did. I know its a different dyno and all but still.

They weigh the same too! ;)

You really can't compare especially when it's totally different dynos. If you we're to compare mine to power figures most of the MX5 tuners give I'm making crap power as they quote 220-240 wheel hp at 12psi, I'm making 255 Flywheel with a bar of boost and more ignition advance than they typically run

Edit: above two posts echo my feelings, they weren't loading the cars up anywhere near as much later on in the day

K20's love cold air, so I suspect the CTR would have made closer to the 200HP number in better conditions to be honest.

Who needs a wastegate when you got a crack like this :p

I have no more excuses.
 
Nah it was there, it's about an inch longer now though.

Anyone know a good welder? I had it welded by someone I know is a decent welder but it still failed after probably 5 hours of use. I might just bin it and buy one of the new steam pipe ones you can get. Shame none of them are made unequal length like the Tomei one, I really want that unequal length sound.

I think given time and experience to improve the airflow, ambient temperature regulation inside the cell and a better way of removing the exhaust gasses, along with more hands on experience with the Dyno which can only happen with time it'll end up a good venue.
I found it a bit cheeky that the price was higher than many other RR group sessions, considering the operation was still very much in its infancy.

They need to get some metal rope tie downs instead of those flimsy things that kept melting and snapping or just need to learn how do run on certain cars with no strapping.

They need to learn the dyno better, with a maha they could have adjusted the loading on it to say 75% run up to make it easier on some cars.

Ventilation and cooling needs some work, the M3 really struggled with heat, first run 345BHP, then 327BHP. Opened bonnet for 10 minutes and pointed fans at engine. Shut bonnet and re-ran it made 355BHP and car was still over temp reported on dash.

Next time shall clamp SMG sensors down to run bonnet open like they did at Powerstation as it always made 370-390BHP there. Very happy with 1372kg for M3 though with full tank of fuel and heavier trim pieces in the car.
