Looks spot on Rob, just keeps getting better.

Your tap in points in the charge pipe for your Apexi are they the revotec ones? I'm needing something similar for my DIY intake pipe.

 

[Feel]

Looks almost perfect, Rob.

I say almost - have you thought about running the vac lines and injector wiring under the inlet manifold?

Edit: Sorry, Reading it back, it seems a bit rude. Wasn't meant that way.

Not sure what DV that is, but if you could reverse it, you could bring the vac line around under the inlet manifold, under the TIP and in up the back? Just a thought.

Yes, self-sealing Revotec - never had any problems with boost leaks etc. so they appear to work well.

 

[RobDon]

Could do that Feel yes, although the injector wires are too short to reach from underneath as i already tried that, so I'd have to lengthen them, job over the winter me thinks! Routing the hoses underneath is easy enough.

 

[Feel]

I think lengthening them would be best, but I saw something on "Beetle Crisis" that might work, some of that woven-fabric-ish sleeving and a length of wire (stainless/alloy) rod so you can make the wiring run precisely where you want it, bending it to suit.

A nice straight run of wiring with radiused bends would look loads better.

Mind you, probably have to chop the plugs off to do it, so might as well just lengthen the wires

 

[RobDon]

I have that woven sleeving and heatshrink, sounds like a plan for a winter job to tidy up that area this winter.

Alot of people ask how to keep their silicone hoses nice and shiny, well I found a new product that does a really good job, isn't sticky and smells nice too!

I managed to get the hoses and loom running underneath the SEM manifold, looks WAY neater, here's a couple of pics:

I've got a load of new t-bolt clamps, so I'm working my way round the IC pipes and hoses, replacing the worm-drive clamps with the new, beefier t-bolt clamps, just to be sure nothing blows off!

 

[Feel]

VERY Nice, Robbie.

Before

After

I was going to comment about the braided vac lines before, I definitely think it looks better in normal hosing.

thats a really tidy engine you have there ! Did you buy that coilpack heatsheild or is that somthing you made ! and does that sem Manifold still have all the vacum stuff still bolted to the underside of it

Have a look in the INA Engineering section on here, he sels them and they are quite cheep.

 

[Feel]

Silver powder coat on the charge pipe would match the inlet, I think, but would it look too much like the LCR/TT charge pipe? Black wrinkle finish, maybe? Might be too much black then...

Yes all the connections are on the underside, Don designed it that way for a clean look.

Nothing new to report, I have upped the boost to 1.5 BAR, the turbo can take it since the rebuild, wastegate duty cycle is only 45% which means the turbo isn't trying very hard to make boost - good stuff! Car pulls hard and feels great on the road.

 

[RobDon]

Can anyone tell me what MAF sensor I have? It's marked: BOSCH F 00C 2G2 049, at the bottom it says 492 09 3 C. I think the other number says 027 291 042. Is this the normal 180 Cupra sensor?

1.5 bar?

is that a safe level Rob....? I read somewhere that ATP only recommend 1.4bar (can't remember where though)

can it cope with and sustain that amount of boost?

 

[RobDon]

Yep, the heavy duty 360 degree bearings can handle 30psi of boost so 21 is no problem! CR Turbo remember, not ATP!

I would still be slightly sceptical though

I know the 360 thrust bearings help, but is the casting and housing up for coping with that sort of boost?

how did you turbo blow last time (sorry that was quite a few pages back) it was due to the compressor wheel right rubbing against the inlet? is this related to the standard bearings, which have now been uprated to 360 ones?

what sort of power do you reckon could be achieved with running 1.5bar?

I may ask Bill to look at this aspect on Sunday.....

 

[RobDon]

Blew due to bearings and oil seals going (primarily oil seals), which caused the compressor wheel to hit the housing - most likely down to not being built right in the first place. It was running 1.4 BAR for years before it went, so the boost was not the problem.

interesting

will see what Bill says when I see him on Sunday. however it is set in P-Torque's map to hit 1.4bar, and anything over this would cause it to go into limp mode (Will's words not mine)

I am tempted to see if it could be pushed to 1.5bar.....

OR what the duty cycle means is the wastegate starting pressure is higher so the required % duty is'nt as high. Whats your static actuator pressure Rob?

consider an MBC if so.
