Why doesn't revo make a difference !?!?!

[Andy vRS]

I touched on this on another thread. But to start things backwards, my mate has got a 05 Fabia vRS with 1400+ miles on the clock. His has been Revo'd and has a proven 182hp and 307 lb/ft. To be driven in the car it feels very fast, more so than my stock vRS. My car is a week old, and thanks to the bank holiday weekend has just done 1000 miles. In every scenario we could think of my stock Fabia is exactly the same as the revo'd fabia in on road performance, whether it is mid range or standing start acceleration.

How can this be !?!?!?

Those figures are peak figures...you might find for the majority of the time there isn't much difference between the output of the engines.
For example, before the turbo spools up, I'd imagine there is very little difference between them...once the turbo is spooled up, it will probably be quicker, but it's still over a relatively narrow rev-band.

If your going from dead very much the same sentiments as rob.

Tell him to keep his revs in the band as much as poss and youll become very familiar with his reg plate and sooty exhaust!

[Andy vRS]

We might go on a private track and try beyond 100mph, because they are evenly matched to that point. So the main issue is my chums driving technique we think ?

[Jon TDI]

There is little difference below 2K rpm. Above this, a remapped vRS will be more eager to rev.
I'm suprised you found there isn't a difference in mid-range performance. The peak torque is usually shifted to around 2.5K rpm.

Well from a chasing down of Fabia's on track I can say that a standard Fabia is nowhere near a tuned one.

The 180's aka Revo'd ones held there own and some, only really catching on braking and corners.

The "stock" ones were quite nippy in the corners / very short straights (about the same as revo'd ones, hard to compare on slow corners ) but didn't have the guts on exits and straights of there breathed on fellows.

Dare I say it driver skill is a huge varient, perhaps and I don't suggest you say it to your friend, but perhaps you have the Fabia sussed where as he may not?

I know I keep dropping back to Jap engine style driving or almost red lining, where I should change after 5...amazing how much that slows you down.

Swap keys...bend it pay for it rule, but that would do it for you, and you should after a few miles of adjusted to the slight changes...

[Andy vRS]

Hmmm - you could have a point there Colin. I think i will reserve judgment until a) mines been RR and b) i have taken his out for a serious run !

what kinda 0-60 do they both do?

[kaivaksdal]

Hope this helps get to the bottom of this, thought I;d stick in my 2p worth.

The standard VRS is a seriously nippy car and (providing you keep it in the 2000 - 4000 rpm power band) it really does make excellent progress. On a super chilly day, standard car ran just over 8 seconds 0 - 60mph.

Revo'd VRS on a super hot day (TRAX 2004) with gentle gearchanging, mine ran 7.1secs 0-60mph.

0-60 is only one area of performance though. Try a standard car and "optimised" car beside each other at a given speed in the same gear. Floor it and you will see the "optimised" car is far faster. 100lb/ft and 40bhp is a big difference.

Something else to note (apart from different driver skill - staying in the optimum rev range and not revving the nuts of it which is pointless) is that even this kind of difference is not so easy to see in day to day driving. A well driven TDCi is not too far off but then we can keep up with 330i BMW and 350Z Nissans. They have much more power than us, but the difference in real driving is not that big.

You need BIG POWER to see a huge difference on the road.
Try it with a Porsche turbo though and you will see the true meaning of POWER.....

MHO only you understand.

[Andy vRS]

So in the real world, which we all live in, the "optimised" car is a bit of a waste of ca$$H. This 0-60 lark made bugger all difference about 10 times over the other night when we were out and about.

[eatsoot04]

A standard Furby would not completeyly kill a corsa. It would beat it but if your looking for performance like 10-15 car lenghts away you will have to look at some extreme power difference. In my opinion the £400 is very well spent, feels loads more, loads more fun! (if you use it right) (and if your friend ACTUALLY does have revo and is not just bulling you! ;-D)

[ColinD]

Yup...in short I'd have to agree.

Scenario, queued up behind a Porsche (no idea which one, not a boxter) off he goes, off I follow to 60...off he goes to 100, off I follow...off he goes to 120, off I follow never really loosing any distance on him.

Brake Brake Brake to a 40 max right hander...Porsche flies round, Octy understeers panic, ESP saves...that is where the moeny difference is visible...pooped my pants, but was happy to have kept well in touch with somthing 30k+ retail value.

I know which one I'd rather have, but I know which one I have and possibly enjoy more often.

Many scoobies of say 300bhp find Ian glued to there backsides on cross country runs. Partly owing to the smaller k03 turbo (faster spool compared to the scooby) but also the on off power sprint nature. Only on much longer roman roads do the scoobies wind up enough to be at peak boost and thus pull away.

Tracks are the only place to level the playing field. Any road test will always beat me as I prefer to drive home so will always be slower despite having maybe more power, taking the 1.8t I own over the Fabia.

If anyone needs convincing on sunday that a "slightly breathed on" car is faster than a std one ill be happy to demonstrate

[Andy vRS]

Yup - i will line up for that ride

[RevoKev]

Interesting thread this one... as above to see a very real difference side by side on the road you've got to be running at a much higher state of tune. Driving technique is a very big factor in how well a car performs. As Colin says swap keys and have a play... the reasons for enhancing your cars performance will all become apparant!

[Andy vRS]

Thanks Kev. Having been in the car lots i think it feels a lot faster, it just isn't, but Adam, my mate, is taking his car back to JBS to have it looked at again, although he did have it RR at 182 and 307 lb/ft which i think is one of the highest in both regions. Either way i am getting itchy feet now, i am desperatly trying to avoid modding - lol....
