Porks bike carbs and boost project

[pork]

That went on a lot easier than I thought, few nibbles out the bracket and bumper will fit straight on.
Debating whether to get some facelift bumpers.....hmmm

Bought another set of carbs, repair kits were £15 each (need 4!)
So got another set, this time had long conversation with seller to make sure they ain't all cruded up.

Facelift bumpers on a prefacelift look the the nuts.........not colour coded though!

 

[pork]

Yeah, defo with you on that!

 

[pork]

New set if carbs arrived today

So put on all the replacement push fit airline fittings and other crap, bolted them on got float bows full off fuel this was the first attempt off starting



Fired straight up

Plus, it works fine with jus the boost FPR without all the solenoid/pressure switch thingy I made, so happy days

It pops and bangs quite a lot though, why is this?

 

[pork]

After seeing frank do this, I've been dying to try this



So, what do you think?
Good or bad?

Here's what it'll look like when all joined up

 

[sr20bud]

Thanks mate, getting there, waiting on couple of deliveries and its turbo time!

 

[superls]

looks good matey, one thing tho, when its all up and running, get a wirebrush round the engine bay and paint lol

Haha defiantly!!

Plan is get it working now on driveway, run it about to work out kinks, then spend hotter months making it look pretty

 

[pork]

More presents came today

BOV 'T'

Backlit boost gauge

 

[pork]

BOV I ordered of t'bay didn't come, so money got refunded.
So poped up to sfs performance round the corner to pick up a 45 degree hose, and sold me a recirculating BOV for half the price they sell them for beings I look after there compressors.......it's shiny too

Hopefully get this all plumbed on over the weekend.

 

[mas12555]

Nice work mate .

 

[Rob]

What boost you planning on running mate?

 

[pork]

Dunno yet lol. Low to start. Haven't really done anything to lower compression ratio, I'm hoping the larger 1.2 head iv fitted will drop it a bit. Haven't got the gizmo for testing yet

 

[pork]

Got this lot fitted today

I have a few issues though that I'm gunma need help with please.

1- To get it to start, I have to blow into the float bowl breather tubes (connected to pitot tube)

2- Once running, it won't idle and still pops and bangs a bit

3- the boost/vacuum gauge is very erratic, and when I give it throttle, it barely shows any boost.

I'm still waiting to get O2 sensor

Any help will be greatly appreciated

Cool project, but you should have perhaps got a figaro inlet manifold, and then mega-squirted it? Anyhow, those pops from the video above was due to a lean condition. Make sure if you get an 02 sensor its a wideband one. I'm sure you were going to anyway, but narrow band is a total waste of time.

 

[MicrAde]

You need some anti-lag Neil

Yep, defiantly getting the wideband.

Would the lean mixture be the reason behind why I have to blow into float bowls to get it to start?

That's jus insane

Possibly. I always found those carbs really temperamental on the K10 when I first tried this. You've ended up with really quite a complex system there where there is much to go wrong so its a bit hard to say.

Haha, great!! I done this coz I thought it was simple, and learn few things along the way.
Last k10 had cbr carbs and ran sweet!

Last piece of the turbo puzzle arrived today

Oil scavanger pump, came from America, and got stung on customs charge
Pump itself was only £97

Bit larger than I thought tho!!! I put a £1 coin in pic for comparison.

Jus gunna feed oil return into dipstick hole, tempory measure until I can move car about to get it off my ridiculous sloping driveway.


Gunna take carbs of, again, done bit of reading, couple of things I need to do to idle mixture, need d-shape tool, but il get round this with trusty dremmel and cut some slots in fir a flat head.

 

[karlj]

Have you spoke to a bike shop to see if they can help you with the d shaped tool?

 

[pork]

Yeah, but that costs money lol slicing is free

 

[MicrAde]

You gonna have this sorted for meet on Sunday Neil?

 

[pork]

Hahah, on back of a lorry maybe

 

[MicrAde]

Hahah, on back of a lorry maybe

Soooooo need to see this car done

 

[pork]

It's close to running! Need to sort idling issue first.

Then there's gunna be a lot of messing about setting up/balancing things.

Then brakes, suspension, wheels............aren't cars great!

We love 'em, thats why we're all here

Says him who a few short weeks ago was ready to introduce his car to a gallon of unleaded and a box of swans!!

How very dare you!

 

[MicrAde]

How very dare you!

Sorry . I am back in love with it now though

 

[pork]

That's more like it.

They are a cruel and mysterious mistress.

 

[pork]

Had carbs off, using trusty dremmel, slotted stupid d-head thing so I could adjust idle mixture

Had a look at old carbs, and they has these on......

So swapped them over so it's gunna be a lot easier to set up

Good job I check ed to as the needles on one of the screws was snapped and missing!

 

[Rob]

Awesome!

 

[pork]

Awesome!

F**king freezing taking carbs of today! Couldn't feel my fingers at all.
I really wanna get them back on and get this thing running! But still chucking it down with snow

 

[pork]

Made this today, drip accumulator for bottom of turbo.

This was return pipe that came with turbo:

Added this compression fitting that was laying about:

Had old bit of exhaust and sheet too:

Stick it together

The finished product.

Manufacturer of scavanger pump says it can suck up oil From 1 foot above turbo.

You'll be surprised how cramp its getting in the engine bay now :-/

May have to relocate battery to the boot at this rate

 

[pork]

Was jus thinking, would I need some sort of breather on it?

 

[padraicR]

Admiring your originality on that little piece build it with what you you can find , there the little bits your always most proud of

 

[pork]

Thanks!

 

[pork]

Knocked up a quick bracket for scavenger pump,

Now jus need to find a good space to weld bracket to the car

 

[MicrAde]

Do you ever do any 'work' at work Neil?? Coming on well matey

 

[pork]

I jus use my breaks productively

 

[frank]

you could rear mount the turbo now you have a scavenge pump neil (hide the tubby in the boot )
and i doubt you will need a vent, maybe a (ballbearing turbo) type restricter in the feed line, or electronic speed controller ?

 

[pork]

That would be cool!

You don't think a breather is needed? Iv asked I'm another forum, and some say yes.

 

[frank]

i think a breather will aerate the oil personally mate, you may have to drop the voltage on the pump so that it can just about empty the catchcan @ full rpm,
i dont think you want any "suction" in the turbo exit fitting

 

[pork]

Thanks , il look into that then, how much oil actually goes through the turbo?

 

[frank]

Thanks , il look into that then, how much oil actually goes through the turbo?

only a trickle for a ballbearing one and my journal one will take about 1 min to fill a teacup @ high idle

 

[pork]

Underestimated the size of this pump, cheapest about tho, even with coming from America

 

[pork]

This jus arrived

Jus need air/fuel gauge and then il make a pod for all 3 gauges and switches for fuel pump and scavenge pump
