boosted yellow mk1

[Williamspaul]

Just read the entire thing, brilliant.

Is the yellow sunflower?

No it’s lancia integralle yellow

More to come on both my cars 🚗 🚙

Thanks- I thought it looked yellowier than the Renault shade. Giallo for the win!

So I’ve been having a bit of a nightmare I switched to a 172 coil pack after ditching the r8 coils and it hasn’t started since turns out a 172 coil pack doesn’t have an igniter (whatever that is) so the adaptronic won’t run it so the custom made bracket custom ht leads all are useless yay

On top of that by using the 172 coil it may. Have damaged my ecu double yay

So to solve the immediate problem I’m now using some sort of vw coil with a built in igniter and some random leads which are look like they won’t fit that nicely but they will fit and have had to get a new custom bracket made but that at least that looks great

 

[Williamspaul]

Here’s the custom downpipe I had made I decided to go over the subframe as I hated the last one going under

 

[Williamspaul]

New oil feed to clear the downpipe and over the subframe instead of under

 

[Williamspaul]

I went for a valved system so I can have it loud and very quiet

Love your project 💯. Great seeing it come together, real nice work and parts. It’s going to be epic.

 

[Brigsy]

That will be pretty quiet with 3 silencers in. My trophy has two decent silencers on a 3" system and barely makes any noise.

I would have got the cutout pre silencers for maximum asbo

 

[Williamspaul]

Small update it now runs and drives it doesn’t idle yet but mapping is on Saturday hopefully that will get sorted out

 

[Yosemite Sam]

Mate that exhaust is a work of art!! Fair play.

It’s. Actually a valved system that I can switch between one box and three so I can have the best of both worlds Asbo and quiet

 

[Williamspaul]

So mapping happened today car surpassed all my expectations safe to say I’m very happy with the results and yes it is insanely fast

 

[16V F7R]

Awesome 🙌 🙌

 

[Yosemite Sam]

Bravo 👏🏻

 

[Yosemite Sam]

Any vids of it doing its thing?

 

[Adey.]

all sorts of awesome, defo need some videos

 

[Yarp]

It deserves those results for that absolute work of art exhaust.

 

[Williamspaul]

 

[16V F7R]

That sounds 👌what a result 😎 Can you list the spec?

 

[Williamspaul]

It has a slightly oversized (1785cc) wossner forged bottom end 8.09:1

64mm 172 throttle bodie

Mark fish inlet rally spec Megane inlet

Ported 2.0 meg head with 33mm valves

750cc ev14

Kent rn1601 cams (2degrees advance on inlet 1 degree r****d on exhaust)

Gt2876r on a log manifold

Lighted and balanced 172 fly

Jc5 089 with lsd

Mishimoto j-line

2.5 inch boost pipes

Full 3 inch exhaust

Walbro 255 (at its same limit)

Adaptronic 420d ecu

Is that 26.9 psi? What’s the max you could push that too?

 

[Williamspaul]

Yeah 26.9 psi the turbo had more to give but we were at the safe limits of the fuel pump so had to call it a day there

 

[Brigsy]

Great power. Out of interest, any difference to power with exhaust valve open or closed?

 

[Williamspaul]

Yes there was a power difference 3bhp I suppose that shows how good the exhaust is

 

[Williamspaul]

So one of my core plugs had a tiny little drip I destroyed it getting it out but I’m pretty sure it had rusted through not creeping around the outside I also changed the starter motor while I was there as it seemed a little. Intermittent

 

[Williamspaul]

So I’ve been out in it a few days now yes with the leaky core plug I couldn’t resist didn’t even have to top up the coolant and the question I expect everyone wants to know is can it get 413 bhp to the floor ? I’m happy to report yes it can very much so ! It’s the way Chris maps them he’s just so good att it yes the big turbo Makes it laggy (fun) but it even comes on boost it’s so controlable

And I don’t think I mentioned it before but we managed to get the boost by gear working by connecting the speed input to the little wire that come off the speedo cable despite Peter saying it wouldn’t work 😂 so in 1st and second it only uses spring pressure to hold the wastegate closed and that’s 300bhp we couldn’t make it make any less than that 😂 then 3rd upwards it has the full 413 I also have utilised a old fog light (to look oem) switch a so a boost cut switch that allows it to run 300bhp all the time if I want to but I haven’t pressed it yet lol

Chris also enabled launch control set to 5,000 rpm but I haven’t been brave enough to try it yet 😆 but should help a little to get it off the line

All that said it is insanely fast it pulls in fifth like it pulls in second it fifth gear ⚙️ will pull it off the clock in seconds it’s absolute madness how it goes from 120 to 150 I’ve never driven anything quite like it I’m very happy with it

 

[Williamspaul]

Been having a pretty bad wheel bearing drone so while it was off I took thee opportunity to remove the camber shim

 

[PerthRS]

This is seriously impressive work on all fronts. Nice!

That Jc5 must be holding on for dear life with over +300ftlb (+400nm) running through it between 5000-7000rpm?

Im starting to think that the jc5 isn’t going to be enough I’m considering a o2j or o2m gearbox

 

[Williamspaul]

Spent a little time making the rev counter work

Vw box is the way forward.

 

[Williamspaul]

Vw box is the way forward.

It’s the only real option however it complicates the Speedo situation

 

[Brigsy]

Speedo cable on these or electronic?

Mk1 Clio is cable

But there’s no cable drive on a o2m

 

[plees]

Exhaust is a work of art! 😍

You can buy boxes that go on the cable to make it work, using a vss sensor and toothed ring on the shaft. Something like below.

Electric to Mechanical Speedometer Cable Drive Conversion

Have you put a modern transmission into your classic car, but want to keep your factory mechanical speedometer working?
