Wheels could be off the ground in that video. Just saying.

I'm more worried at how the fu** the mpg is going up

god help anyone that listened or took advice off your drivel! you will not automatically make more BHP at all, As the knock on effect of the higher duration camshaft is you loose some torque because of this do you not think peeps have already experimented with uprated cams for the PD already????

the stock cam suits the lower end turbo's that spool early and have nothing after 3500-3600rpm the uprated cams suit the bigger turbo's that can make power/bhp after this RPM, thus moving and or increasing the rpm power band, so yo can hold onto that peak bhp figure for more rpm in some cases you can see BHP increase but these have been very marginal & as of yet i've not seen proven results so like i said the Jury is out on if the claims are true for the 30bhp increase that is quoted

but of course you need a fair comparison to measure these which isn't easy with some of the dyno figures that are flying around at the moment LOL!

the latest is 292bhp on stock nozzle on the 2260.............!

 

D\RIVEL!!!!!1111ONE!!

 

At least I can do maths, please explain your understanding of camshaft timing, duration, lift and dwell and how changing these variables affects delivery of power and torque.

 

Because you need to have a better understanding of these things than me if you're going to disagree from a technical perspective. Pub talk won't cut it.

What ever gear they want. At a guess most will be 2nd.

 

Just been looking at Steve's video again and comparing it to gear ration of the long box. So he starts in 2nd finishing in 6th. Steve please correct me if I'm wrong.

Steve, out of interest what were the road (or track ) conditions when you took this video?

 

After watching it again, it appears that you very roughly do 30-130mph in about 12 seconds.

 

That seems a little unbelievable even for a 300bhp Fabia if I'm honest. A 700bhp RS4 did the same in just over 12s by comparison...!

 

I doubt the instrument cluster has been recoded to suit the different final drive ratio after the gearbox change, not much chance of the speedo being even remotely accurate.

You could alway use VCDS lite to log a group which shows mph.

can't help but watch that video and think its a petrol the way it rev's, i don't know of any diesel that will jump/rev rpm and mph that quickly in 1 gear or even sound like that?

sounds more like a motorbike engine noise dubbed over the top lol!

Seems a fair bit faster than my pulsar despite it being 200kg lighter! Although it's had very little work done to it I'd still expect similarish performance.

 

Heck it even seems faster than a big turbo pulsar running 430bhp surely that can't be right? Much higher power to weight ratio but takes longer to go off the clock @110mph.

but like he said, if you increase the RPM at which peak torque is produced and the torque stays the same then you will automatically make more power (at that RPM), that's just a fact because of the way BHP is calculated. obviously you might not make peak torque at the same RPM as peak power and you might not gain anything in terms of peak power with a different cam buy you'll have to make more power than with a standard cam at some engine speed (and very probably less power at certain engine speeds)

ok if you say so, remind me again of your experience level? years you have been tuning and modifying cars, have you even owned a tuned PD engined car

all well and good reading the books posting up info that easily obtainable off google but can you actually put any of it into practice???

 

don't try tell me how to suck eggs little boy, been there and done that long before you probably even born!!!

ouch speedo is taken from the abs ring on a fabia vrs doesn't matter what box you fit the speed is the speed of the shaft, but you might be right about the cluster as its defo different from a stock vrs that i have ever seen

correct yes you will as long as certain elements and figures don't change! which in this case they will to gain somewhere else you have to sacrifice elsewhere

 

my point was i've not yet seen any proven results from fitting race cams to a PD engine, i'm not saying you won't get them but i'll hold judgement for the now!

 

if all this done and then combined with meth/nos and max the dam thing out for max bhp then yes the results will be impressive but how long will it last and it'll be fuking awful as a road car

lol good job then as the utter drivel he posts on here on many topics/posts are laughable

 

anyhow totally going off topic tbh

 

that video is sham, utter *******s not a hope in hell that a (supposed 300bhp) vrs would rev and accelerate that quickly

 

race cams results have yet to be proven and certainly not to the 30bhp as claimed combined with other mods yes but not just bolt in adjust map and away you go 30bhp thanks very much!

I'd like a group 11 and group 3 log so I can then calculate the VE of the engine. But at that power the MAF maxes out so would be best done at stock boost.

Meanwhile, in Wales, steve is lurking (logged out) on Briskoda laughing his arse off....

 

And stroking his leek...

A 2260 powered VRS would leave a standardish Pulsar with ease

You mean Sheep not Leek?

Maybe depends what your definition of standard is. A standard with 220bhp it probably will even though it's lighter it loses some power through the 4wd system. A moderately tuned one running !bar of boost, exhaust, front mount, filter will see around 300bhp so then it's a little bit different. Still going to be lighter and still going to be able to put the power down. Then we look into uprated injectors, MAF and turbo and it's a different ball game without spending stupid money like a couple of the guy's that are running around 500bhp.

 

But nether the less it's still quite impressive given it's diesel.

Can't wait for my first go-pro footage of my speedo when I am back   Amazing what one video can start

Based on your own experience does Steve's video seem legit? I understand your both running similar power so perhaps you can shed some light on it.

Looks quick to me.  The only way to know its not sped up is to have some "normal" music playing in the background, and a video with a counter on it.

 

I never did a 30 to 130, but I know my 0 - 110 was about 13 seconds, but I know that first 30 is easier and quicker to attain than that last 20mph thanks to gearing / aero etc.

 

Oh, and there should be a santa pod meet as well as a trackday.    Or ultimately everyone attends the same dyno setup on the same day.

Fair enough that's still bloody quick though seems quicker than it should be just makes you wonder why people tune petrol cars if a 1.9tdi is capable of that.

 

Here's a dyno plot from a member running uprated turbo ect but standard internals. I'd imagine it's a similar spec to the video I posted above.

 

Because it's a tough old block, can it reliably take that power to an extent... yes and how big are your pockets.

Some old audis and Honda have forged blocks from standard so little 1.6s and 2.0s are capable of handling 400-700bhp just by whacking a turbo on.

Don't make them like they used to.

I think you may have just answered your own question. 500+ BHP is easily achievable with a decent 2.0 turbo petrol engine. It won't be cheap though, most Group B rally cars from the 80's were around 650 BHP as are Rallycross Supercars these days.

Loving this thread!

 

As Dan said... Steve is definitely lurking in the midst reading all of this though!!

 

 

As Jason said... need a national Briskoda rolling road day as well as the national meet!
