Andy,

I went from 7A exhaust cam back to standard AAN (inlet & exhaust) and it felt stronger on the standard cams an I guess 480 bhp at 1.75 bar confirms its running well.

Water meth helps greatly with temperatures mine was cruising at 22 degrees and only rose to late 26's on full boost when I logged it.

Mine isn't mapped for it, it just gives a little top end protection. .4mm jet coming in at 1.1bar.

Darren.

A few of you saw the car at the MRC dyno day and AITP on the VRS stand last weekend

Updates -

I forgot to mention that after getting the EPROM writer i ran Dmitri's diagnostics on the ECU and could see intermittent knock pulling back the timing, so we suspected that the cam pulley was still not quite in the correct location and had this corrected and verified. Dmitri also pulled back the ignition timing slightly, and there has been no knock causing problems since.

The car ran near identical figures on the MRC dyno compared to my last run, so if there is a problem, i've still not found it.



I've had the head bolts checked and they're all good, plus some maintenance (hydraulic fluid change, looks like i have a slight leak, oil change etc), cut-out the rear arch liners to further reduce rubbing and installed the aerocatches which works really well on the front bumper (photo to follow).

The oil cooler is sat in-front of the rad so i'm going to get this moved to a better location and re-install the aux rad, but plumbed into the WG rather than as stock. This should help my temp issues massively.

The car is running really well, but i can't help but think its still slightly below where it could be under optimum conditions.

A few people have also suggested that the cam setup (ABY inlet, RS2 exhaust - the bane of my life) is really not helping me, and that a 7A set would be far better for performance.

Water meth also looks like a good route to keep inlet temps down, but given how well the car is running at the moment i'll likely be leaving these "performance mods" for a later date. The car is utterly devastating on the road.

The car is in desperate need of some coilovers. The koni's that i replaced a couple of years back seem to be feeling shot already, and the ride height is to low for sure on the H&R springs, causing me further problems, so this would be a good mod for the future.

The paintwork is also looking pretty bad given the rust bubbles on the arches and rear quarter, and the cutting of the front-bumper and flaring of the arches. I hope to get the car into a bodyshop this winter if funds allow

[Rusty]

Might need to do a bit of bending or get a shaped plate welded in there.

[Sonic]

I hope so, given that the mounting plate is about half as deep as the latch mechanism itself which sits into the bumper so it's flush on the surface.

[Rusty]

Nice. Is there enough room between the two for the mounting plate?

[Sonic]

They come with a rubber bump-stop which will do this nicely...

[Rusty]

Sounds interesting.

To take out the movement, you could fit a rubber or foam ring between bumper and wing, it'll also stop the paint rubbing off.

[Sonic]

Yeah, there are already some holes in the wing so i can bolt the pin to it at a right-angle, then mount the latch into the bumper and should all be good.

[Rusty]

Where are the aero catches going to go then Andy? On the side of the bumper?

[Sonic]

I've got a Dremel (no MadWolf comments please ) and a set of aerocatches so will give a go at installing and see how we get on with the bumper!

There does appear to be a decent amount of movement even with the catch on, but hopefully i can still get a tight finish with them.

[andy10v]

could this increase in coolant and subsequently oil temps be a result of the coolant now also being passed through the TiAL wastegate

Seems like a reasonable thought, you have added a new source of heat input to the cooling system, and have not added any way of removing the additional heat. So if the rad was previously near its cooling capacity then the TiAl could introduce more heat than the rad can get rid of.

[Sonic]

Yeah you'd want 2 bottles to fill her up and top up as necessary.

Doesn't sound like you'd just want to top up with water if required.

[A80Avant]

All I can think of is when you get a leak of some sort and you have to top it up etc.

Sounds promicing

[Sonic]

Ill give it a go when we have 32c over here
