Torque figure is way off though surely

To throw a wild card in the mix. What about the TMC tuning box, Anyone tried that?

I personannly wouldn't use one on a petrol supercharged or turbo charged motor but id consider it on a diesel

std figures are up 10Hp more than they should just as the mapped fgures are up 10Hp more than they should be. In a nutshell the dyno is overreading by about 10Hp

My car ran on same dyno and gave out 175bhp at 1500 miles stock within a couple of weeks of that mine had standard filter and was on normal shell fuel and was not run in at all, I also made 176bhp on another dyno before this in another country. it is possible that the above is correct for BHP torque does look high to me. My Mk1 Fabia BLT engine code made a lot more stock than it should have as they all did. Post map mine made 206bhp and 320(something) lb ft.

I sent you a pm mate. you are more than welcome to have a go in mine regardless of some claims they are not quick, they are great cars for the money given that you get a good one and thats coming from someone who swapped a 2008, 325d 240bhp for a CR170. Drive the car then tell me I am wrong

Yea they are not to be compared to a turbo petrol, it's a great car for a diesel best value one for performance I can think of and that's only when remaped, still great MPG and cheap road tax. There the performance claims of the car end.

Agreed, to be honest I nearly bought the petrol, however for me the deal was better on the diesel.

Plus your saving the planet with all that reduced CO2 and burning less fuel even at that. The bike is another story that's where the fun is at, my old bike had more BHP than the Octavia

Only way you'll get a no argument result without taking the engine out and testing it is to bolt it a dyna pack system, like they have at Thor Racing. It's an interesting experience seeing your cars hubs bolted to it . The only figure you'll get is hub (wheel) power as they don't calculate (guestimate) it back to the flywheel.

Dyno readings will always be all over the place. Don't ever take them as gospel (not that I beleive gospel either).

Diesel turbos and petrol turbos are a completely different driving experience. If you're a fanatic for one, then you'll never like the other. If you also try and drive one like the other, you'll hate it more.

Does a stage 1 Shark remap give you quicker 0-60 times and top speed if so what are the differences, providing you have elected performance as your main priority.This is on a 170cr tdi off course.

Yes. Other maps are available too.

top speed is governed by the gearbox not the map. What the map will do is allow you to reach your top speed much quicker.

I do like the idea of having a quick diesle though. Would be nice not to have to see horric mpg everytime i boot it.

Get yourself a bmw 123d or alpine d3 biturbo then. You're into trackdays, right? Both are rwd, too, which should make them more fun at the track, too. Otherwise, get an Audi a5 3.0 diesel. All three should be attainable for the price of a blackline, as long as you're not fussed about buying secondhand.

Unless it's limited, which the CR isn't.

What gear does the top speed (circa 140 'supposedly' in the tdi 170's,be that PD or CR) arrive in? If it's 6th then it's a case of running out of power before revs. 6th looks to be geared for about 35mph/1000rpm so at 140mph you'd only be pulling 4000rpm. Not sure what the rev limiter is set at (assuming there is one, not tried to find it myself TBH) but there must be at least another 1000rpm available. Not that I'm saying the derv could achieve a top speed of 175.

140 mph isn't too shabby though!

Presumably wind resistance becomes too great at that point. Not enough power to push on through. The air is pretty 'thick' at that speed!

Gather a decent remap makes the CR a reasonable amount quicker than a standard TSi; 310 - 330lb/ft of torque is on the cards too; thats remapped S3 levels of punch. I think the lure of great economy and not having to worry about super unleaded is a boon too

You cant compare torque of a diesel to torque of a petrol car. The diesel needs to produce more engine torque to equate to the same torque at the wheel.

Hence why a petrol with 300lb/ft will walk away from a diesle with 300lb/ft.

Its all down to the gearing and diesels have longer gear ratios. This is probably why a remapped Cr with 200 bhp and 300lb/ft is similar to a pertol VRS with only around 200bhp and 200lb/ft.

Thats why proper 4WD cars have a low range box as it effectively double the torque at the wheel when in low range. Obviously it assists in descents with engine braking but the added torque in low range just proved the petrol vs diesel theory.

To be honest i wouldnt remap my CR as the front wheels spin up all to easy as it is where as my remapped BMW could handle all the torque you could throw at it. Ultimately the biggest limiting factor when tuning it will be wheelspin i would have thought.

+1 on that, horrible wheelspin in stock condition already. As for being slow. I can't say it is. Naturally, petrol is faster, but that is not the goal is it. Goal for a diesel is to be economical, which the CR170 is for sure and fun to drive at the same time. I have noticed that it doesn't feel "underpowered" for me at any speed. And I have owned some rather quick petrol cars before. As for a trackday car - not a good choice I'd say. Nose is heavy, no traction. However, I might change that opinion after warranty runs out and I will upgrade the suspension.

Here is the data for MTM stage 1 map:

max. performance kW/Umin 151 / 4000 125 / 4200 max. torque Nm/Umin 385 / mit DSG 380 350 / 1750 - 2500 v-max 230 km/h 224 km/h 0-100 km/h 8,1 s 8,5 s consumption 6,5 l 5,9 l

237kph / 147.265mph was my personal best in my last cr170.

Havent tried this one.

Can't say in standard form I've any issue with wheel spin, only on wet greasey roads does it happen. But then I've got a dsg so maybe that's why?

Remap is on my list to do but want to sort out the suspension etc first.

Mines DSG but it definately spins up easy enough. Same was true of othe FWD cars ive owned so it is by no means an octavia characteristic mearly a FWD one.

My BMW's were far better even in the wet. Given the choice id have RWD every day, far more planted. OK things were a bit pants in the snow but thats easily remedied. I would imagine 300lb/ft through the front wheels would be wasted at least 50% of the time. Only once up and running in say 3rd gear would it be under control so to speak. I have to modulate the throttle very carefully when pulling away at junctions to prevent the TC kicking in and considering the roads are damp up here for the majority of the year then i just cant see a remap on the VRS as worth it.

Remapped my quattro, AWD scooby and RWD BMW as soon as i got them as i knew they would handle it but i have never had the inclination to map any FWD car ive owned.

In the end of the day i think the CR VRS is fine as it is.

Ah I see, well must be me then. I'm well known for driving slow......must buy heavier boots!

Get a WALK fitted, should reduce the wheelspin.
