I'm only interested in the diesel version (manual).

 

I was just wondering how much power can you get from a vrs estate, the model specificity is the Skoda Octavia 2.0 TDI CR DPF vRS 5dr 'estate' 2014 to 2018.

 

Average mpg 61.4 mpg, Engine power 181 bhp, Acceleration (0-60mph) 7.9 seconds, Top speed 143 mph, Drivetrain Front Wheel Drive.

 

How much power would you be looking at with stage 1 through 3 remaps? (I understand to go for a stage 2 - 3 remap you will probably have to modify the car, like turbo charger upgrade and exhaust and air intake upgrade, which will increase power)

 

Also does anyone have any in site to this car remapped and the driving experience on the road? For example can how well it put the power down and such?

i have a new exhaust and CRD3+ pulling around 240 bhp, its very hard to put the power down in the wet pulls like a train in the dry (closer to 150mph now). Look up golf GTD to see whats possible but with our any engine mods turbo etc you will be limited to around 240 with a remap. 

if you want big power you are wasting your time with a diesel TBH

Thanks for the reply. I have a few questions. firstly why are you limmeted with a diesel, this might sound silly but i don’t know why? what about the petrol version then? can you get big power out of them with a remap, turbo, exhaust etc.

There's more of a market for tuning on the petrol side of things. Your stereotypical (and I stress the stereotypical) diesel driver is just looking for a car which has a high mpg with a good tank range. I bought mine with a diesel because I wanted to tow a trailer without the car fretting about towing a trailer. Plus £30 VED and 60mpg appealed to the tight git in me 

 

Petrol side of things, the sky's the limit. It's just a case of how much you'd be willing to spend. Stage 4 tuning, nitro meth injection (or nitrous oxide), a turbo  the size of a house, an equally stupidly sized intercooler and a thru exhaust and you're looking around 450 - 500+ horsepower.

The only thing i don’t understand is why you cannot map the diesel engine to them figures? Can you just not do them types of mods to diesel engines?

You probably to be honest. You'd need a tuner to do a custom map on a rolling road. With this engine being used across the VAG world, if it was possible, I'd have thought it would have been done already.

 

Can't say I've seen any Stage 2 or above diesel maps.

.

The diesel's exhaust system would also potentially cause an issue. DPF and cat side of things.

Power costs. How fast can you afford to go?

 

More seriously, there are limits as to how fast you can make the flame front advance, and they come in earlier on a diesel engine than a petrol.

So you either go for the fuel economy of a diesel but are limited to the max power output or go for the petrol that you can go crazy with but you’re looking at less fuel economy, and of course the difference in the drive of a diesel vs a petrol. I’m guessing that the diesel is rappid at 240 brake anyway? especially for someone like me that will be coming for a sub 100 brake car?

Without tearing the tyres to bits, the best 0-60 time I've done is 6.5 seconds. With the dtuk pedal box, I've got it setup so I can, when conditions are appropriate, I can use the available extra power. If you turn everything up to 11 it; does drive a bit wild, will wheelspin 2nd gear too easily, torque steers too easily with the esc in sport or hesitates to accelerate in the wet with the esc on full.

 

With how I've got it setup, it's rare if I'm wanting to do an overtake do I need to shift down a gear. It just goes and goes and goes. If you accelerate a bit too hard, it still does wheelspin, but only if you floor it.

 

I came from a 1.2 72hp Hyundai i20 and that struggled to get to 60 in less than 12 seconds.

i’ve seen a few people say it doesn’t put the power down well. i guess you wouldn’t want to take it to 400+ bhp.. the first few gears wouldn’t be usable. I think i’ve heard that you can remap a car so that if it’s got more power than i can put down (like a lot of tuned front wheel drive cars) so that the engine limits the power output and gives you more and more power the higher the gear. but if this is true what’s the point modding it tom such high power? Do you have good tyres?

That's sort of right, but badly put. It would be more accurate to say that you can map an engine so that it won't give full power in the lower gears (some manufacturers actually do this themselves). What's actually determining the available power is the gear selected though.

Hello all, the diesel is very limited to get big power as it's got the the dpf/cat which stop them from breathing aswell. If you had a custom exhaust which removed the lot then maybe you could squeeze a little more power out of it but then you'll need a friendly mot man/centre to pass it. I've never seen a big turbo kit for the diesel either. 

 

The petrol engine is that good in the vrs/gti/r why would you go for a diesel.

 

My vrs is running 400bhp used daily and I can get 47-50mpg out of it on long runs. Mainly alot of my driving is short journeys work, school, shopping etc etc and I still get over 35mpg.

 

Go for petrol....

Darkside Developments have a big turbo kit for the 2.0 TDI engine.

https://www.darksidedevelopments.co.uk/products/darkside-gtb-turbo-kit-for-2-0-16v-common-rail-engines-mk7-platform-2013.html

Have you bought the car already? If not, cancel the search for diesel and buy a petrol. I can't imagine why you'd want the diesel if your first thought is lots of additional power. 

 

The petrol is plenty quick with a remap and a simple stage 1 remap puts you on the door of 300ps. You'd need to spend significantly more on the diesel to get it anywhere near.

Hmmm.. On the graph it is only 240hp so that figure is for factory turbo, I guess.

47 to 50 mpg sounds great for 400 bhp. I’ve seen that some comapnies install a stitch that controlls the amount of boots you give the car so for daily driving you can lower the bhp and increase it when you want. do you have any youtube videos of your 400 bhp car?

with my car atm i get around 40-45 mpg with good driving, obviously less when i put my foot down, if i can get them same figures with the pertrol engine at 400 bhp then that for sure what i’ll go for. 

 

ive seen one video online for an exauhst system and it sound decent.. i would for sure want to go with an exhaust with a valve so i can close it when doing long journies.

 

thanks for the reply’s everyone.

I'm not sure what exactly constitutes good driving, but unless you only ever do short trips, the TSI is capable of mid to high 30's, or 40's easily if you do longer A road or motorway. My long term average for my stock TSI 220 is 38mpg over 2 years and 30k miles. 

 

Nothing with 400bhp when regularly fully utilised is going to return 40-45mpg, whether petrol or diesel. Don't forget diesel is around 10p more expensive per litre now than standard 95 unleaded, or around 5p more than 99.

 

How many miles do you do per year? If you have to spend hundreds more pounds on mods to get the same power, plus you are paying more per litre for fuel, I can't see why a better mpg from a diesel would matter.

This is the closest to why diesels are power limited. The way the flame is created with compression makes it more difficult to time the combustion. All of this contributes to a lower max rpm. The higher revs is where the petrol engines make the big power.

What's the 'normal' boost pressure on our diesel engine at the moment? 40psi on the hybrid one on that chart seems high.

 

I'd assume, as well, you'd need to have one hell of a remap to get all those additional components to work. Plus, if you're increasing the power that much, wouldn't you need to have some additional cooling? Be it having a bigger intercooler and a bigger radiator?

There are different specs of turbo upgrades you can choose from. There is a comparison table further down the Darkside Development page.

Each one will give different amounts of power, but it’s really the torque values with the diesel engines.

The OEM set up is charge cooler, with turbocharger integrated into the exhaust manifold. The Darkside turbo kit includes new tubular exhaust manifold.

Not really sure if the charge cooler will cope, but Darkside recommend upgrading to an intercooler & removing the EGR valve.
