nah... **** it Im more bothered about the O-Ring Seals on the ends of the rails...

David

 

ttt for weekend.

David

 

nice to see its progressing david, and it all looks to be coming together.

not had opportunity to view any mail you may have sent, so wont be able to reply untill monday.

cheers

Steven

ps your probably in the pub aren't you??

 

hmm... I hadnt actually made it to the pub at that point... 10mins later and I was

No hurry, just let me know when youve found the tank

David

 

Just been and cut the flange for the downpipe with the plasma cutter.. I Want one now!

Also aquired a scrap piece of metal to finish of the fuel rails..

David

 

When i made mine, i had to make do with an angle grinder, hacksaw, and 2.5" holesaw... cutting thru 12mm steel plate aint easy. You took the easy way out...wimp

 

Easy way out? Still had to clean it up a little bit..

I was going to just drill lots of holes.. and then chisel it out.. using a plasma cutter was my dads idea.. still its done now

Slowly getting there.. but I need an up-pipe before I can sort the downpipe..

David

 

I did use mild steel for mine, but im sure that with the heat that builds up there, thicker wall tubing may have been better. Mine was just a bit of old cossie downpipe, so basically std exhaust tubing approx 51mm OD, but pretty thin walled. I think it is possible that it may melt at some stage if i giv it loads of abuse. Of course it may not, I was just in a hurry to get the car going, so used what was lying about, and if it does *** up, I can sort it later.

 

Some more pics...

Flange for turbo.. still needs some cleaning up which Ill do after welding...



my impression of an elephant


Erm... Same... think my humor might have something to do with stella and becks.. and going to the pub at 4.00...


David

 

Looks good
Rob

 

BTT

 

Arh Arh

Perhaps this idea could be adapted to provide a cold air feed to the filter

 

btt

 

need an update of where you are with the rebuild

 

no further... Need more gas for the welder before I can do anymore work.. and my supply of pub co2 has dried up... so account at boc time...

David

 

Anyone know why there are water pipe connections on the bottom of the trottle body ?
Is it just an attempt to cool the throttle body and post-compressor airflow ?

Never noticed those pipes until now

Nor the little solenoid hidden away underneath the inlet manifold
(just see pipes disappearing all over the place ! -- did try to map them all out once, but the fuel canister related stuff confused me)

Thats the great thing about this thread, you get to see things that are normally too hard to get at

Keep those pictures coming David !

 

The coolant lines to the throttle body and ISCV are to prevent the throttle and ISCV freezing up. Might be worth bypassing the lines during the summer months, to keep charge temps down. Coolant tends to run in the 75 to 85ish centigrade region, you want you inlet charge to be well under that level.

The solenoid under the manifold is the evaporative emmisions systems canister purge control valve. The ECU uses the valve to trigger the release of petrol vapours caught in the carbon canister into the engine under certain conditions.

Not anymore it doesn't

The big pipe on the back of the iscv should run to the inlet prior to the turbo shouldnt it?

Where do the two breathers on the tops of the head normally run to.. Cant quite remember so wanted to check first!

David

 

Same place David, pipe pre turbo, that's what coats your whole induction system with oil.........
Far better lead them to a catch tank Otherwise it's like asking the engine to breath its own f4rts and enjoy it

 

Cheers...

need to make a catch tank now then... might just do it the tim w way

What about the little mini filters you can get?? are they sufficient or is their alot of crankcase etc pressure?

David

 

You will get a little oil 'mist' which would soon make a mess, I just lead them down to the ground behind the starter motor, never get any oil out them, just a few condesation drips.

Don't forget the main breather from the block to the inlet manifold too !

This is starting to mess with the crankcase ventilation system which can lead to condensation within (on short journeys) but does not cause any issues if your oil gets up to temp regularly

 

yhm

 

thats really very interesting andy.

I always wondered, apart from being inconsiderate to raod users, why dont people just lead all these pipes to open up somewhere near the gear box?

Is there really that much oil mist that you could create a hazard on the road?

If there isnt then why go to the difficulty and hassle of catching the stuff, only adding weight, requiring space, and maintenance to keep it from over flowing.

On top of that, you have to be careful to make sure it isnt restrictive!

 

Adam

I don't think for a minute it could cause a hazard on the road but if it is continually venting into the engine bay things can get a bit tacky. I use a fine stainless steel mesh in the breather pipe vertical sections leading from the heads and crankcase, this acts as an oil trap and it drains back to the engine.

Andy

 

But watch out at MOT time, coz over here they will fail you for venting to atmos. The oil mist wont do your intercooler efficiency any favours, it also contaminates the inlet charge. Assuming the rings etc are sealing well, then there shouldnt be any oil escaping through it, but filtering it is a good idea.
A few american cars, and other performance types use a crankcase evacuation system, whereby a PCV valve is installed in the ( free flowing ) exhaust system. This will then create a vacuum in the sump/crankcase, once the ex gasses are travelling fast enough, reducing blow by, oil contamination, ( and oil leaks ) Not too sure what sort of mess it might make out the exhaust, but it cant be that bad if they use it on drag cars, and other big power v8's etc. It also gets a mention in Vizards Mini book. I was going to do it on my Rover V8, but just never got round to it, as its easier to vent to atmos, through a good filter/oil trap, to stop any oil escaping.

 

Wasnt this ridiculously long thread, once about an intercooler??? or am i dreaming?

 

LMFAO at stevieturbo..

It will be back on track at the weekend... Just need to get some welding gas.. Otherwise welds will look like an Aero chocolate bar..

David

 

I have nitrous

Move over Im coming past, till I run out of gas...

Will post details of cicuit to control soon...

Ill give you a clue...

Voltage comparator (monitoring Map sensor)
PWM Controller With Ramp Increase...

This =

Resulting in Nitrous at wide open throttle until preset boost level...

Oh Yes I am MAD!!! and I love it! Cant Wait for the gearbox to die a nasty death...

Will try and get up early tomorrow and aquire (sp) some more co2 (for the welder stupid!)...

Then again Im off to the pub now!

David

 

The use of NOS for taking up the lag, is a good idea, and also uses a lot less gas than using it at full throttle normally. How about a 200bhp kit for starters. That should all but remove any feeling of lag.

 

nice to see you again david, you are mad

car looks more complicated in the flesh than on pictures, good luck.

would 200bhp jets on noz set to come in before the turbo hits full boost give a feeling of drop in performance when the noz stops and turbo comes on full boost, just a thought. or are you still going to give it a bit of gas when on boost??:
