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

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.

They are really open and cool guys, just glad nothing is wrong with the M3 and today it kept making power right upto 8000rpm so no timing pulled.

Ramp up issue they already have sorted and they will further improve cooling and extraction, they said they would send me some photos when done to post up. :)

I think most cars were pretty spot on, yours was down because of a map issue and like you say dyno reflected what you felt on road.

They also agreed that when Mac is ready they will re-run his Mustang for free and how some heavy weights on standby to keep it down and no spinning up. :D
 
Did they comment on the traction issues btw? Was that down to the dyno ramp rate resisting being spun and therefore breaking traction? Or anything else?
 
Might be worth telling them to stock up on Wynns Belt Dressing to use instead of WD40 for improving grip.

My power figures we're more or less spot on as well, less power on "high" boost than I expected but maybe I was being a little optimistic having the stock cat and center exhaust

Don't recall any wheelspin issues apart from on the big power Mustang, most other cars seems reasonably fine apart from the stuff with turbo's coming in early.

In fairness I remember wheelspin being quite bad at Powerstation my M3 had issues there whereas at Ti it did not, difference being Powerstation never strapped it down and Ti did.

Really hard to say, maybe some cars were too light, gone off tyres I mean my Mustang ran with zero issue, so maybe it was something to do with ramp rate early on but as my Mustang and M3 ran with no wheelspin issues hard to say.


P.S. WD40 is what maha recommend, I've seen other dyno's use WD40 as it softens rubber and have also seen some use adhesives too. Maybe something they can experiment with or ask Maha about.
 
Wheel spin wasn't an issue during the ramp runs, but it was during the setup before they began the runs (Where I commented on hard they were loading the cars up)
 
I have a feeling I may actually have a sticking caliper looking at my graph. I have a 31% loss (50hp) on the rundown for flywheel to wheel power.
Plus it almost sounds like there's a stone in the rear caliper sometimes that goes if I dab the brakes, perhaps it's actually something more.

You must have missed a lot of the cars with traction issues then if you don't recall any :p

Bonnets up on cars will help them too :D

I did spend most of my time outside chatting, was too loud inside. :D

I think now they have sorted ramping issues things will be greatly improved. For their first big dyno day they did well.
 
They smoked my tyres several times when setting up. Wasn't particularly impressed as they are very sticky, soft compound sprint tyres. By the time the runs were finished the tyres were hot enough to take the paint off the floor and were steaming when it was parked outside on the wet car park.
 
Mines in there as we speak for a new timing chain, sort an exhaust blow (I'm sure somethings blowing a bit at the manifold/cat end) perhaps after a week or two I might take it back once the chain is all good for another run. Without the engine light on! :D
 
When I popped get my car earlier (which I must say is running loads smoother after a new chain and valve clearances done for the second time this month!) Matt mentioned some improvements are in the pipeline with ventilation and cooling, all a learning curve and as it is it's installed as per Maha's recommendations but always room for improvement. I think it's a good venue so definitely worth considering using again :) And as Gibbo says they're good lads and happy to listen to feedback and help you out.

I'll be using them more often for work on mine at least and I'll put it back on the rollers soon I think once I see how it feels on vtec when I've ran the chain for a few hundred miles. Won't be happy until I have a print out with 200BHP at least! :D As it feels much quicker than the power graph suggests on the road and I've had numerous cars faster than the Civic with near on 300BHP.
