Very cool

 

wow! Must have been quite a day!

 

So...... heard of some interesting numbers being laid down

 

It was an awesome day haha, a bit hot, but kwaze..

 

there are some big differences in numbers there

 

Yes, I believe starting from #8 it was flipped, so if u see the Hp first, its going to be Torque, and etc, the last one is mine, so the correct one was 185 whp and 163wtrq

 

Hmm.....seems to be no "Wednesday" build cars there Just real ones

 

That Johnny dyno still hurts, don't it.

 

Sorry did not know either? I was just commenting on dyno figures on stock R56 JCW since I am thinking of getting one in Feb. Sorry if I offended anyone in any way.

 

Yes those cars were run back to back, within the same hour.
The high HP R56 JCW only had 1500 miles on it, the other had 8000.

Both cars were bone stock. It just illustrates the differences that can happen between 2 theoretically equal cars.

Hey Bill,

Is your car still the same as in your mod list? I would be shocked if your still running that MTH tune?

Looking at all the figures I thought he had a RMW tune

 

 

Public domain......

 

Either way, PD or pirated from SCMM, it is good to see results from a well attended dyno day.

Can someone tell us about the dyno and the shop, since not all of us live in the area. Is this hub horsepower or a rolling wheel dyno, type?

Thanks Don

 

Sorry about that! i Didnt noe, i already took off mine, if u dont mind taking it off too, it'll be greatly appreciated

Thanks, and sorry guys

 

OK its off, sorry fellas did not know either

 

Thanks guys for removing the dyno number images.

 

Sorry, mod list updated.
Leaving to run it at Bonneville next week.

Bill

 

This is a Mustang 4 wheel dyno.

The shop is a very large facility that houses Dynamic Autosports, a primarily Subie, EVO & Drifter focused business, & ABF, which is Hubie's business, now joined by Mike and Jason from Mynes Performance. I would guess the facility is at least 5,000 to 8,000 square foot two story complex.

On Churches dyno a stock GP will put down 180 to 188whp. The stock GP at your dyno day put down 184. So where is the 18-20% correction factor come into play?

Johnny's turbo car put down 318 at Hubies, and put down 315 at Churches, again, where is the 18-20% difference?

I find it hard to understand how one must "setup" the dyno for that day. Are the calibrations and correction factors being changed from day to day or car to car? How would anyone know what a correct number is at any given time? Is the dyno that erratic with it's readings?

It seems the stock GP and stock R56's dyno'd right where they should, it's the rest that are off. The stock GP appears to laydown the baseline for the rest of the numbers........unless the dyno is just plain broke.

 

I knew I should never have mentioned anything that could be misconstrued as suggesting different dynos put down different numbers.

I have removed any such info from my previous posts as it adds nothing to the original topic.

I would appreciate if you would do the same.

This discussion had nothing to do with the OP's question as to which tuner was best.

Both tuners have satisfied customers and that is all that really matters.

We have different opinions of how this stuff works, and I will just agree to disagree.

I would of been easier for you to turn up Big Howe, you could of claimed top honours and had all the data you needed to compare.

Mind you as the calibration is the same as the weekend why not book an appointment and pop down there I'll pay for your dyno and gas to get there

 

It went off topic with Randy's post and has ended up here, tough to change. Your post back to me was quite lengthy about how big a difference there is between Churches and Hubie's dyno, then edited back out. The question still remains, how does a stock GP make the same number on both????

Why is it this certain folks need to keep "re-calibrating" their dynos. How screwed up could a dyno be for it to have to be re-calibrated to a 100hp change at the 300hp level. So are all the numbers from before the re-calibration BS, or are the numbers now BS?

I guess I could beleive the dynos reading differently if the stock GP, the two R56 S, and the stock Coopers didin't run such standard numbers. It's all the modified cars that put down strange numbers. Are the calibration numbers being changed for each car? This would make sense looking at the results but would seem to be a big no-no for any credibility in one's tuning abilities. How could one ever believe any numbers produced from that dyno?

 

That sounds great Paul, seeing as though I'm 600 miles away and leaving for Europe in a few hours, not very realistic. Besides, when modified cars(cam, pulley and tuned) are putting down less power than stock GP's, there's some bad mojo running around that place, I'd stay as far away as possible from it.

Unless of course the correction factors are being changed for each car, in which case all bets are off.

I'll be at the Brighton Speed Trials, how about you guys bring these 1320 cars and big turbo cars down and put down some times vs all the other makes so we can see what they do in the real world.
