Hi all,

Finally got round to putting my car on the rolling road after having the stage one shark remap..

Makes 160.1 BHP & 275lbs torque.

Wanted to know if it would be safe to ask for BHP to be raised to approx 180 BHP on my standard clutch and flywheel?

Presumably it's torque that kills those?

Thanks in advance

Driving style will kill those whatever the power, constant launches, flat out at low revs & high gears.

maybe turbo won't be able to handle 180bhp for long? I'm sure someone will be here with input.

if they can limit the torque im sure 180 is achievable

if im wrong some one with more knowledge in this area please correct me

Thats a good safe figure i would be happy in the knowledge my turbo clutch and flywheel were operating at a nice safe figure!

Balls out on a pd130 you'll struggle to get any more than 175

Mine runs 181.8bhp and 302ftlb on standard clutch and DMF.

The DMF is starting to show signs of ware at lower revs/high load. Just have to me mechanically sympathetic!

Could that be torque tho Fabia Tom?

Without a doubt. Search "Show us figures" you'll see I have a sharp torque spike.

On the other hand i made 185bhp with 275lb/ft on my pd150 today

Torque can be seperated from bhp

On my old yellow one i ran 200bhp and 299lb/ft torque

In a short answer, no your clutch and flywheel wont take it.

As soon as your clutch starts slipping you'll wreck the flywheel and your looking at £500 just for an uprated single mass clutch.

This is why i'm not remapping my diesel. i cant be arsed to pay up to £700 for a new clutch kit. I'd rather wait and upgrade the whole car next year for something along the lines of a Leon FR or a octavia.

If you are careful the standard clutch and DMF will handle quite a bit more. I'm currently running 200+hp and 300+ lbft on a standard 84k old clutch and DMF.

People tend to focus too much on a figure, Shark maps are smooth like an oem map, no nasty torque spikes and perfectly drivable, you drive on the torque, not the headline power figure so enjoy what you have

I still don't tink you can separate torque and power when power is a calculated number based on measured torque but, from memory, my Ibiza was running something like 225bhp and 250lb/ft so you don't have to make big torque to make over 200bhp

oh, and smooth like an OEM map...lol?

The standard clutch and flywheel will cope with more power than the standard turbo will, providing its a decent map. As jase said, bearing in mind a RR will only give so much accuracy I'd be happy with that, safe level of power.

No im just saying dependant on the mapper the bhp can be healthy and the torque safe if they know what they are doing

For example (my old cars)

Fab vrs - 173bhp and 342lb/ft (bad spikey map)

Hybrid fab vrs - 200bhp and 299lb/ft torque (good map)

My current pd150 leon - 185bhp and 275lb/ft (again good)

My oem map was horrible. Massive spike then nothing

One thing I have learned with maps is, ignore the RR figures. Different RR's produce different results based on the operator and make of RR, weather conditions, heat soak, how the RR operator gets cool air into the engine etc. My old remapped MK1 Octavia vRS went on quiet a few RR's in its time and had figures from as low as 205BHP to 230BHP+.

Take one RR's figures with a pinch of salt, get some more sessions done elsewhere and compare them. If the RR operator has the franchise for a competing tuner its not unheard of for them to make competitors maps look poor by skewing the figures (easily done).

Mapping I find is all about how it drives afterwards, BHP and Torque figures are only as good as the RR operator, the weather conditions, RR brand etc.

A fabia before mine on the same dyno'd standard 143bhp then I had mine on and it made 180 it made **** loads of torque but lowered it to around 310 lb ft.

I think the max safely if you want to push it is around the 175/180 bhp and from the lots of reading I've done this is a realistic max figure I'm pushing my car a little it's custom mapped but I'm mechanically sympathetic and it doesn't get booted often.

My map is very very smooth too.

Care to share your graph?

absolutely, high peak torque wil generally be a spike fairly low down in terms of engine speed. will make the car feel fast and sound good when quoting numbers, as people only quote peak numbers. I'd be surprised if your Leon isn't better to actually drive than your Fabia was

Its a strange one

Torque low down makes a car 'feel' fast! When in fact it really isnt.

I prefer a nice pogressive map. Doesnt feel as out and out fast but it is far more sympathetic to the car and in reality probably is quicker

Thanks for all comments so far, will post the graph up tomoro for all who are interested

Tbh I wasn't all that bothered about knowing what it was until the other day when I had a chance to test the fab against a celica gt on the dual carriageway.

We were both coming off the roundabout and then onto another straight on a clear empty road in the early hours. He went for it but i passed him easily as we accelerated from about 30mph and then held him off until I took my exit further down.

I thought those celica's were good for 170bhp and yet somehow he never got by - he was approx 3 car lengths behind throughout.

Would imagine it was my torque that screwed him from the low speeds, but would have thought that with greater speed he would have passed due to extra revs and more horses but that didn't happen

Im not advocating street racing btw - it was a dual carriageway with roundabouts in the wee hours

Id like to know on what basis more BHP kills the clutch or flywheel though as some are very adamant this is true but I would have thought it was more a torque thing...

Im planning to buy the dark side 230bhp conversion kit in the next couple of months as I hav saved up for it so wondered if there would be much harm in asking shark to up the BHP by 30 or so in the interim??

Its torque that is a killer for clutches and dual mass flywheels

If your going to go for the darkside kit i suggest you fit an uprated clutch and single mass flywheel BEFORE you get the work done

Thanks Big Jase

Only thing is I don't think I could stand the SMF rattle :-/ it's chattery enuf as it is....

Can I not just buy a standard new clutch and be mechanically sympathetic? :)
