Tuning enzo on a rolling road.......205 bhp!!!

[gadge]

check this out! this is a photo of enzo taken by the first owner and club member SchooweeNick on a rolling road a few years back. i found it whislt trying to uncover some previous history on it.

As the print out says, 205 bhp (208 DIN?) which i belive was achived by a re-map and a GSR induction system. the GSR has long going since being in my ownership, however the remap is still there which explains it furious acelleration - especially in 2nd and 3rd

As well as the re-map and induction kit, enzo also sported yellow calipers first then a set of brembos and also a set of 19" gloss black OZ superturizmos!!!. SchooweeNick must have known his stuff as it was him who lowered it even more with ebach springs and managed to drop the front end more than the back to give it that "agressive nose down" look ...... when you think of the mods, it must have cost him a fourtune!! wish he left those brembos on though?

has it still got the one off custom exhaust?

sorry to raise it but blacked out it says power tyre(wheel hp?)132bhp and dispersed power(transmission losses?)73.7hp???
i did 2 rolling roads,1 standard car got transmision losses of 16hp, and 1 after smf,q2 diff and new synthetic gearbox oil of 12bhp losses.(both 4th gear, closest to 1:1 ratio)
i cannot see how it had 70bhp losses unless brakes were on or rr operator made it happen for results.
im always suspicious of losses over 20bhp , most impressive gains ive read usually have 30 or 40 odd bhp losses, so i tend to pay more attention to whp.
if i was on that rr i guess id have had 245.2bhp.
im glad you like the car but be suspicious of that rr readout.

Posts on other forums suggest some rolling road readings need to be taken with a significant pinch of salt. Interesting to see an OMP sticker on the slam panel...but no strutbrace fitted!

They were 18" Superturismo wheels, not 19". I went to a couple of shows with Nick.

no just the stainless one fitted as part of the gp package..... thinking of getting a cutom one next year though? its top of the list.

......im glad you like the car but be suspicious of that rr readout.

who knows what it is now? but it would be interesting to see what a standard abarth is really putting out if they loose so much BHP along the way?

eventually he did get one fitted, then removed it prior to selling leaving me with the holes for a new one to be fitted..... needless to say, its now got one back on!

i must admit, i don't know alot about rolling roads? why is it that people are sceptical?

Because if you take the same car to six different rr's, you will come away with six widely different results! I suspect it's down to poor (or non-existent) calibration.

 

[dave]

this car has been on many different rolling roads, all came out about the same iirc

 

[cledan]

I often hear people talking about BHP losses over time, yet if a car is well maintained I fail to see how these losses occur, indeed I recall mk2 or 3 Golf Gti's actually gained 10 or so bhp after 100k miles due to engine loosening up!

I stand corrected!

The losses I'm talking about are transmission losses, from drag on brakes, friction in cv joints, differential, clutch and flywheel.
All similar cars will be different to a degree.
Figures can be manipulated by operator and that's the bit people are sceptical about. The rr measure whp at the roller, then at the end of the run measures the transmission losses on coast down,also barometric figure and temp can all be slightly out to increase the calculated engine hp.
A regular statement tends to be your 150 bhp car has been remapped now has 200bhp, but on pre remap rr figure is also usually high say 168 bhp . So has it gained 50hp or 32hp or 32 hp minus the percentage out it was out at 150, say 10% so 32 - 10% = 29 bhp .
Try to stick with same rr you trust , compare whp.

I guess its not a nice thing to say, but I don't trust any, they all manipulate the results to suit the circumstances.

WOW! i did'nt know there was so much maths involed in rolling road results!! , i must admit i always knew there would be some sort of power loss along the way - although not that much - but why would a rr company want to fix the results? i mean there just paid to give you what the machine says?

 

[rattystilo]

the main point of a rolling road is to get before and after results so you can see what difference modifications make. You will always get different results even on the same dyno on different days but they should all be within 5% of each other.

And here they are...I think. And pretty rubbish finish TBH (if you look closely).

I have a close up photo somewhere. I'll post it up during the day.

 

[dave]

so who has the exhaust now then if its not on this car?

thats the ones! looking at them now, they do look like 18"s, i could have swore that some said they were 19"s? ....... but yes, i much prefer them in silver......... each to their own i guess? just my opinion.

that would be great! if anyone has any info on this car and any stories i would love to hear them?

not sure bud? the brembos, the strut braces and the exhaust were sold on? i really like the brembos thought? but they look well expensive?
