Rolling Road on 27th.

seems good figures to me mate

Wheel HP seems the only way to read the power as different dyno's can change the settings for the flywheel calcs. for example your first dyno seems to be off around 18% losses whereas today is 12% losses

Think the 'norm' for a GT is around 15% which going off 228whp would give you in the region of 268fly hp

Thanks for your input Mike and what you say makes ALOT of sence.

I was thinking how the fuck could i make more at the wheels but almost the same at the fly?

Need to get it down to England and use a dyno dynamics again, thats what was used the first time.

thats great news!!! glad its nice and healthy and the not starting problem finally got resolved

no more "kangaroo-ing" now?? lol

I was talken about you aswell buddy, saying you were a top bloke.

Nope its not acting like a kangaroo now mate lol much better to drive and not as harsh, really impressed.

nice figures beatz.

glad its all sorted for you matey

 

[Dave.]

Did you see hubbygt's Glanza there beatz? Its been in for just over a week having the finishing touches put on it

Should be collected on Saturday

Also, I'm sure you'd have made a fair bit more if you'd used the whole rev range. Even so, thats an awesome figure, and the car is a testament to you mate! I'm sure you know, but its not all about figures, I bet it drives sweet now - Even the fusion map you had when you took me out for a spin was craaaaaazy!

Glad its starting too - we'll have to get a meet sometime soon again, with the three of them back and running well! (Just collected mine from the garage yesterday!)

great stuff mate.

Get it on a dyno dynamics roller and just tell them use the full rev range, would be nice to see what it would be like with the whole range in use.

 

[Iain@CRD]

Thanks guys.

I saw hubbys Glanza there mate and they were telling me the low down on it aswell but yea we will need to get a meet organised.

Dastek were trying to play it far too safe, me and Nick checked out all the AFR's over the RPM range and there all fine. That RR calculation for FLY is defo not correct either. Cant make more at the wheels but 1bhp @ fly lol

the flywheel calculation is probably wrong at fusion motorsport,

dyno operators have control over these calculations, and the calibration of the dyno.

it is possible for dyno operators to make the figures "look good".

the only figure to take note of is the wheel horse power, as this is what is calibrated by the dyno manufacture and should be there or there abouts on all dyno's.

i have spoke to a few operators and the few i have spoken to have said to only calculate a 12% (roughly) drivetrain loss.


also notice that certain tuning firms have rather high drivetrain losses (some have been seen 18% from memory) which makes the owner happy because they look at the bigger number only

so chances are the dyno you used this time is correct

 

[Iain@CRD]

Interesting to know mate and i know there are a couple of RR's local that certainly do this exmaple : 120@whee; with 678@fly some nonsence like that.

I was told the drivetrain loss would be around 15% on a starlet. The Fusion one which was done on Surrey Rolling Road who used a Dyno Dynamics RR is clearly 18% loss and my recent which is Dastek is 12%.

All the less the car does feel much better than before and all my previous issues were all flattened out

You got those graphs mate interesting to see them

Nice result btw

thing is all cars have different losses in the drivetrain, so flywheel figure should never really be considered as the true power.

thats the main purpose of this exercise fella

I agree 100% mate with that comment, not using and tyring to cause an argument but Abbot had 291 bhp atf but only 219 at the wheels according to the Engine Advantages Dyno so i would agree that there are some big differences in different dynos readings aswell.

i didnt want to mention that, but yeah that's a classic example dude

 

[Dane_Bristol]

I am not digging at anymore just going by what the dyno was producing and saying thats all.

Its how it drives on the road that counts well all know that anyways but the graphs are interesting to see how it performs technically.

yeah i know u werent dude, and your 100% right.

i just normally get verbally murdered when i make comments about EA's funny figures

 

[Iain@CRD]

Give me 5 mins and ill have it loaded up. Need to jump onto my PC.

Ahh its your opinion mate what other people think does not matter but you will probably find its the ones who use EA that stand up for them. Either way i dont care doesn't bother me just interests me to see the graphs and the way it all performs. I will go to EA one day just for a dyno run to see how the figures match to the other prints outs i have. Will be intersting. Much like the 2 differences Ian is experiencing wit hthe 2 different rolling roads.

 

[Iain@CRD]

Heres the graphs ...

 

[Chris@CCM]

nice hp but ur afr looks all over the shop no harm to any one.
making the graphs all bumpy u can see the flat spots when the afr dips down in the 10s

 

[Rory]

Nice result.

Just remember, tuned on the Dyno for the Dyno

I run the same figures there not long ago @ 1.1 bar, just more torque.
