No head unit, i will remove it when its sold

I've not done a lot with this car since I bought it, other than sort the clutch problem, wind the boost up high and start playing with the mapping. Currently running 180hp and 280lbft.

Here's a vid of how she goes:

Plenty more mods to come and I'm sure I'll find the time to do a GTi-6 vs HDi video!

Was this 'BellCp' (something like that iirc?) old car?

[jammapic]

Yep, BELLCP306TD from .net.

I've known him for years and couldn't bear to see the car sold to someone else... so I bought it for the collection, lol.

[Midnightclub]

Ahhh thought i recognised the spec list for it, seems that clutch lasted longer than most expected!

[padge]

this the one that went to RS tuning RR tdocuk meet when it started snowing?

[jammapic]

Yeah. That's the one padge.

[Dum-Dum]

Cant believe the car makes so little power for all the mods, who did the mapping / whats wrong with it?

Completely puts me off the Sachs clutch if its slipping with just ~255lb/ft

[padge]

I remember this being very tidy.

[ozonehostile]

How long until *hdi track car *project :-P haha

[jammapic]

The old engine was junk Dum, 50% down on compression. Ran 174hp and 280lbft with a new motor and the same mods. That was on the old whippy mapping and peak power at about 3500rpm.

New mapping by me makes similar torque (I'm limiting it to save the poor old clutch even though it could easily make more) but holds it to the hard cut limiter I've put in at 4500rpm. its making 187hp now at just 1.7bar.

I'm confident this turbo will do 200hp when I sort a few other issues and get back to mapping it again. At that point I am stopping, I'm not going for silly power.

JP

[Dum-Dum]

Thats an awuful lot of boost mate, 1.7bar is 25psi but on a standard turbo I made 163bhp at just 17psi (1.2bar)

[jammapic]

Yep. Probably doesn't need that amount of boost, there's hardly any smoke anyway so could either turn it down a tad or up the fuelling limiters a bit. I think, as an educated guess, it should do 200hp at 1.7 bar.

[Kezzieboy]

Looks tidy, what dash lights are they, looks really good with the red, always wanted to do it to mine.

[Poodle]

Good to see a thread up for this, had noticed he was selling, definitely one of the tidiest i've seen.

The gt17 isn't exactly a big turbo, should think it'll need the boost to keep the power up. Looks good, look forward to seeing it developed.

[Dean]

After following the xud build on tdoc I'm looking forward to this build haven't read through the 6' build yet but I'll have to have a peek at it.

[Arron]

The blower sounds like a good upgrade. No real lag but the top end the gt15 lacks.

home brew mapping

[jammapic]

Well, no wonder the poor clutch was suffering... Ran it up on the dyno again today and the latest evolution of my map shows 350lbft at 2000rpm. Poor thing!

JP

[jammapic]

185hp and 350lb/ft

[E_KEL95]

At what miles was this mapped at..? Just wondering as mines at 164K but not sure wither to map it or not..

[Piggy]

woh. thats a fair bit of torque!!!

[devils_fuel]

All I can say is... JP loves derv .

Another nice motor fella

[jammapic]

I have to say, I do love derv. Despite having a 313hp 350z and a 205hp track gti6 I prefer the little diesel HDi.

350lbft is a fair whack of torque. I knew my map was making a chunk after I released a couple of limiters and wound the fuelling up a bit more... But I didn't know it was that much!

This has 213,500miles on it. Got a freshly rebuilt engine in it now though!

JP

[zx_volcane]

That torque figure is ridiculous

[jammapic]

I'll get the dyno plot up as soon as they send it over!

JP

[Danny2009]

350lbft no wonder it was raping the clutch good effort mate!

[padge]

awesome result jp

[Poodle]

That's an insane torque figure, be interested to see the graph.

Are you not just a little worried that'll grenade the transmission..?

[Arron]

Sweet dyno figures. Map my car now

[procta]

this is a good car! i have drove it before the old engine died, and even helped remove the old one.
the light covers and 406 rear view mirror live on, on my HDi.
it was a good all round car, ( track, toe, genral motor way crusier in one) by christ chris pulled that off with this motor.

[306Puggy]

How does one do mapping then? That' something that has always put me off HDis and petrol tuning that you have to get someone else to tune them for you. If we can do our own mapping then it's gonna open up a whole new world of DI tuning that hasn't been explored before.
