rolling road then to GDI

[geekham]

Well yesterday I took a drive down south to get my 182 onto the rolling road for a power test. Its totally standard and got 139bhp at the wheels which is roughly 178bhp at the engine im told. I was quite pleased with the result.

I then went to have a look at the GDI demo car and I was very impressed. Andy showed me all around the car and took me out in it. The sound is awesome and the suspension is perfect. Despite being 2 hours from home I have definately found my servicing and tuning company and I will be having some work done in the new year.

If your looking for some work to be done on your car give them a shout they are very welcoming and looking at the demo car they certainly know what they are doing!

Did he go into detail about the spec of the engine and who actually built it?

 

[MarkM]

Why am I boring?

I just asked if Andy had told him what the spec was. I would say on a car forum it was an interesting question. Or does everyone find it more exciting to talk about silversions, turinis and cleaning there car?

haha well said :lolup:

 

[geekham]

He didnt go into huge detail as it would have been way beyond me anyway.

 

[ricclio]

wheres he based

 

[TheJesus]

GDI are in Kimbolton near Huntingdon/St Neotts

 

[Lagerlout]

139bhp atw.... 178bhp atf.... okkkaaaaaaay. Over 20% transmission loss? Seems high.

 

[Timmay]

very tempted to go see them for some work next year after good stuff ive heard

 

[Steviant]

Saw that too. Where did you get the R/Road done? Who told you 178bhp?

 

[fmp_]

20% High?

what does it normally average out to then?

just from my old saxo days we used to run on an average of 23% transmission losses.

 

[Lagerlout]

I was under the impression that you should be looking at about 18% for a FWD car..... I would imagein they time how long the car takes to coast down to standstill to calculate this.... but even that doesn't seem entirely accurate.

I propose a motion to ban any mention of flywheel figures unless actually measured at the flywheel.

23% is more 4wd territory!

 

[Martin_172]

i was always told 25% transmission loss for FWD and 50% for 4WD as a rough guide?! cant remember who told me that bullshit then? lol

 

[Lagerlout]

That's absolute b****cks. The gearbox would destroy it self if it robbed that much power. imagine a 400 bhp Evo losing 200bhp through the drivetrain?!!

 

[Andy GDI]

GDI build all its own engines.

 

[geekham]

I was told 28% by the rolling road operator. Im no mechanic so I can only go on the basis of what Im told. Anyway it was 139 at the wheels

 

[geekham]

It was done at Mass Racing about 30mins from GDI. It was reccommended by GDI

 

[John185k]

Rolling roads are very erratic, best getting an average of three seperate RR's.

 

[geekham]

Yeah I can imagine. Has anyone else had a rolling road power test on a standard 182? If so what did you get at the wheels?

 

[TheJesus]

tbh mate it doesn't matter what it makes, the only way to see an improvement is put mods on and take it back to the same place, then you can see what gains you have gotten. Other thing to do is speak to the guys at Mass and ask what other 182's run on average, as most places log their runs against the reg, so they will have a fair few done there, that's for sure.

Averaging 3 inaccurate readings gives you a more accurate result.
:S

 

[diamond geezer]

ive had gdi do quite a few bits for me over the years, and always found them to be friendly and bloody good at what they do. i would recommend them to anyone.

apart from the bit where andy tried to kill me in one the track cars! hehe

 

[RSTuning]

139 wheel on my dyno dynamics is 167 fly!

 

[TheJesus]

16% loss's!

 

[MarkM]

It was done at Mass Racing about 30mins from GDI. It was reccommended by GDI

My car got 205bhp at Mass

139 wheel on my dyno dynamics is 167 fly!

and 187bhp on a dyno dynamics

 

[Riggs.182]

how much roughly is it for a rr test??

 

[Chris n nic]

I usually work on the old add 10bhp and divide by .9 which seems to work reasonably well

my skyline had about a 25% transmission loss IIRC

 

[P111LTL]

my other car a impreza has 28.3% loss from wheels to fly

 

[edde]

Being as most stock 172 run about 144hp ATW and were designed to give 169Hp gives you an idea that losses are abot 15% in the stock cars case diffeent tyres etc make a difference plus other bits. Plus depends if they have corrected etc.

Quoting such huge transmission losses is stupid IMO.
