bought my rs at the weekend (2001 hatch) and I'm absolutely loving it. such a great car to drive.

Was previously thinking about getting a remap, but after last night (i had a chance to take the car out for a good spin) I'm happy with the performance as it is I think...but.....

how will getting a remap to say 215-225bhp form the standard 180bhp affect 1/4 mile times/0-60 times etc? anyone got any real life data?

also how is the fuel econemoy effected.

I'm thinking about an angel tuning remap btw

Welcome to Briskoda. These questions get asked quite a lot. We've got the Search function facility at the top. Give it ago!

hiya fella, i was the same as you not so long ago, if it were me id check a few things that "should" of been done through maintainance before you go spending your hard earned on a remap...

Cambelt+waterpump

check suspension bushes

check centre exhaust mount not about to give way as the welds snap often.

oh and see if the N75 valve has been changed...

i mapped mine and it made a big difference too when combined with a induction kit and forge dv (alright i know the dv makes no power gain). need to replace the N75 on mine as ever since the remap its been slightly lumpy on tickover and sometimes it surges slightly under medium to hard acceleration.

..id also be wary bout power claims as 215+ from a remap alone is optimistic and you'll only get that from an inaccurate RR..instead expect about 175-180bhp at the wheels after a remap. Either way you put it a map makes a worthwhile difference!

I've had my GP remapped by Angel tuning (from 130 to 170 bhp) and it's bloody fantastic! I would reccomend them... very knowledgable... talk to nige...

(mine is a new car though... like someone else said... check everything is in good order before you go ahead!)

i have a revo remap and run a 14.7 1/4 mile time a couple of months ago not sure what they do std...

cheers for your replies guys...

the car is on 39k to bit early for a timing belt? (built june 2001)

forgive my noobness but what/where is the N75 valve?

when u say a remap aint gonna get your power up to 215bhp, why not?

i thought a remap on a petrol turbo was supposed to give upto 25% of the power of the car.

which would put the vrs octavia up to a maximum of 225bhp.

i realise that is too much but if you put the power gain to 15%, which is non turbo cars the power is 207bhp.

has anyone dynoed their 1.8t engine with a decent air intake, exhaust and a remap?

thats wi a carbonio and a N75 inflicted power loss of a couple of bhp.

on a std octy vrs 200+ isnt realistic, sorry... and you can quote other RR's but i bet the whp is in the area of 175-180bhp which is the same as mine. only way you'd get the fly power you want out of a std vrs with a chip is through an inaccurate RR.

With only a remap mine gave 216bhp

With CAI, sports cat and exhaust plus a tweak to the remap it gives the figures below :D

Without a change in turbo a 1.8T won't give much over 235/240 bhp.

Timing belt was due june 2005 on yours.

4 years or 60k, whichever sooner

hi mate, can you post up what the wheel horse power was, im curious?!

Remap, K&N panel filter and Forge DV gave 206BHP 218 LBS/FT.

Wheel output was 155BHP. More power available but boost was held back as I don't have access to higher octane unleaded.

Did consistent 16 second quarter miles.

Fuel economy has suffered a bit as a result.

16 secs seems slow where was that timed may i ask

i was running consistant late 14's with 193 bhp

hi mate, can you post up what the wheel horse power was, im curious?!

sorry to **** on your bonfire mate but your car isnt 231bhp, more like 205bhp, there is no way your car is losing 54bhp through the transmission. i did a post recently bout this and we collectively found the average loss for the transmission for the octy to be 25bhp (ish). As i suspected again, the wheel horse power figures are probably near enough bang on but the fly (which is calculated not measured) is well off. sorry.

:jedi: :soapbox: :munch: :popcorn:

sorry if i seem(i and i realise it could look that way) argumentative but im only trying to share knowledge, if i had been told my car was xbhp and it was actually less and id been hoodwinked id like to know before i went spouting off to mates, it'd make me look foolish and thats embarrassing. id also have an axe to grind with the dyno technician who ran it as its the type of thing that supposed to pick up on.

having said that i know why they do it because most people only want the result for bragging rights... kinda backfires when your asked to prove it on a strip of private road though... again embarrasing!

i'm not saying anyone is right, wrong, or a liar just watching with interest but for the record i am swinging more in your direction Duke(not in a gay way mind i'll leave that to phil).

Pre first remap (on the same rollers) car was measured at 188bhp which is about right for a standard vRS. After first remap was 216 bhp which is a gain of 18 bhp which seems about right for a simple remap. After second remap (plus CAI, cat and exhaust) measured at 231 bhp - 15 bhp gain which again is about right.

And the most accurate measure of all - my ar$

well of course its faster, mine feels alot faster too after a map and CAI, i wasnt disputing you've gained power and torque, all im saying is that the dyno result you posted is very very wrong. 54bhp transmission losses for a fwd car are very off the mark, id of expected that kind of power loss from a scooby not a fwd car. Search my post on this. You dont seem to understand the concept of it, you can have a car that theoretically makes a million horses at the fly but if its only making 100hp at the wheels then 100hp is what you get on the road through the tyres, the rest is wasted. As the power to the wheels is about what id expect from those mods(although there are more qualified people on here) on your dyno result id lean towards that being accurate not the fly power. plus the dyno computer calculates the fly power by measuring the transmission drag on letting off the power on the run down. This can be manipulated to increase the fly power.

Im not having a go matchmaker bud, im just saying it looks like your being misled by an inaccurate dyno asto the actual power of your car.

It was timed by local car club on an airstrip they get occasional use of,but everything seemed to have slowish times, possibly gear not set up properly. I will be trying again shortly.

I appreciate what you're saying about transmission losses, but irrespective of how accurate the dyno is, if the car makes xxx bhp before modifications, and xxx+43 bhp after mods on the same dyno, then thats a gain of 43 bhp, isn't it? If you calculate that my car is only making 205 bhp now, then it must have been making 162 bhp when I bought it (new). I'd better be in touch with Trading Standards to ask Skoda why they sold me a car with 18 bhp less than advertised

And I have to say that I do not think that Jim Curley at Star Performance would consider "manipulating" his dyno! :eek::eek:

Also take into account that my car - if it's making the figures in the dyno printout - is producing similar power and torque to plenty of other similarly modified cars from a variety of other tuners. :)

forget everything else, what was the whp on the first dyno run? from what your claiming then after all your mods its only the same power as mine which has just had a remap and CAI.

what was the whp on the first dyno run?

Don't remember :(:(

But you're assuming that the 54 bhp P drag figure is all transmission losses - I think that it takes into account aerodynamic drag as well. :D

what? im not assuming anything, the bhp drag figure is calculated by the rollers measuring the resistance of the transmission on the run down from the power run. if you trailed the brakes on the rundown you'd increase the resistance and increase the fly power...

findout the power to the wheels on the 1st dyno run...Cos at the moment youve spent alot more money than me and have got no extra power over what ive got. If your cool with that then you must be rich. ID be very unhappy!!!
