W448 VCX Whippy's old hdi

[TY-HDI]

Anyone know where this has ended up? I had it for over two years, sold it to Sam Barker, then he sold in on 6 months later. Interested to see how it ended up.

Pic in it's better days..

[C2K]

They seem to be the only pics in existence.

[Sambarker]

One of Raz's relations (Pboost) bought it

[TY-HDI]

The only pics on my laptop. So it's midlands way now sam?

[Just Sean]

Looks lush on them wheels!

[spike2002]

Yup this was at the rr meet the other week one of raz mates. I have a vid on my phone of it on the rollers

[samass]

Didn't it do really shit on the dyno? Like pull way less than expected?

[Sambarker]

When i tried to dyno it they couldn't get a reading cos the clutch was slipping too bad

[TY-HDI]

What did it dyno at? Whats been done since newest owner had it?

[spike2002]

Iirc it got around the 140 but the car has blowing exhaust and few other problems iirc sure raz will be along soon and answer more accurately

[GTI 6]

Yes it now belongs to us ran 141 bhp and 270ft lb torque
The clutch has been changed now to a helix paddle and holds the boost well
No more slipping Sam lol.

The car only ran 141 because it has a shit exhaust that leaks
Boost leak from the turbo pipe
And a open filter which ain't doing no favours ha ha

All the above will be getting sorted this was just to see what it would run
Nothing has been done to the car except the clutch change
As its been a daily driver

[Ruan]

I love that one as a poor dyno reading excuse..

"Has a blowing exhaust"...

How does a blowing exhaust detract from the peak power figure? Yeah sure the torque below about 4,500rpm will be reduced, but past there, it'll make near enough no difference... I was annoyed when the dyno place I went to told me I couldn't run with no exhaust

[GTI 6]

Obviously you know the car better than me yeah
Thanks for your usefull input

[TY-HDI]

Ruan the hdi really doesn't have power past 4.5k so that's no issue then?

Nice torque figure, shame on the BHP.

Although the place you all went for the dyno day seems quite shit so the figure probably don't mean alot. Does it still pull well?

I've heard about your exhaust antics! Didnt have one for like 6 months or something haha?

[TY-HDI]

Also sam drove with no exhaust at all aswell for abit

Yeah the car drives absolutely spot on just needs a nice exhaust putting on as when I got it Sam had just put a temporary exhaust which it still retains

The boost leak and Induction will be sorted

This was just a base figure to see what it would run .

[spike2002]

When will this be back on the rollers raz? Be nice to see what it makes when its all sorted did look tidy on the day

[GTI 6]

If I roll it again it will be going on a dyna pack hub dyno lee

One of my good mates who runs a garage has just bought a dyna pack
So il be running it to see what difference it makes and the bonus is it will be a free run

[TY-HDI]

How many 306's do you own now raz? Still the same height? What wheels?

[GTI 6]

^^ I have 5 Cossack phase 1 Gti 6,s
1 blaze ph1 Gti 6
1 black 43k ph1 Gti 6
1 white ph1 Gti 6
1 sigma ph1 Gti 6
2 moonstone stage 2 mapped Hdi,s
1 205 Gti in sorrento green
1 e30 bmw 325i sport
1 Track prepared e30 325i sport
A track ready 200sx s14a
2 prelude Gsi,s
And a Zafira Gsi turbo

And loads if breakers parked up for parts

Your old car is still running the coilovers and grey clones it came with lol

Turbocharged Diesels really don't suffer from any of the issues that petrols do with exhausts.

Backpressure is purely there at lower RPMs to keep the mixture in the cylinders where the air inertia isn't high enough to take advantage of the valve overlap and thus is just throwing a large quantity out the exhaust valve. Diesels don't really have this issue, since they're normally turbocharged so the cam profile is such that they don't have much valve overlap and they have a turbocharger on the exhaust side which produces quite a bit of backpressure normally...

Most people have this whole thing that "no backpressure = no power" which isn't true, it'll feel like it has less low down torque, however.

[Dave]

exhausts are over rated

Since my HDi exhaust fell off (just post cat) its much slower bottom end....but surprisingly good top end (if you can be bothered to wait that long lol), didn't realise quite how restrictive the backbox must be!

It's bloody loud though, much louder than running the golf with no exhaust, not really sure why as I thought the turbo would muffle the noise.
