Silver C70 T5 - Manual - 400BHP

sorry to interrupt...on the graph max Lambda value looks to be about 0.87 or [0.87*14.7 =] 12.8:1....is that not a bit high at approx. 1.5 barg?

Which RPM range do you see that? part of the point of the post was to show how important logging is, clearly the injectors needed work at this point as it goes over rich when component protection kicks in, but you don't know without a tool like this. It's richer than Dave's though this is where I found the best torque around 0.8 ish lambda

In between 3800 and 3900 fella, purple line spikes across the 0.85 mark



I don't know much about it tbh but would expect 11's at high boost as you say

Purples bts ram cell iirc mate not actual

Managed to get a few hours to begin the head removal. I probably have to drop the whole thing in the end, otherwise how am I to get the bottom end checked and get rid of the grey junk in the pan?

I've cleared the top & 2 sides of the engine (I wasnt rushing it). If the weather is clear again tonight - I will crack on with the cam belt and the exhaust manifold.

I confess I really enjoyed just pottering, doing it my way.

[Nealevo]

Good to hear, I've just changed the engine and bits on mine and I have liked not having to rush and miss/beeak things, hopefully it will all work out well.

It is nice to have that intimacy with ones jalopy....

I'm looking forward to seeing the ssb up and running again dave and if you can just hit that sweet spot for performance and a decent ammount of reliability that car should fly.
Is this eairly version of the me7 a total pain to tune I know people run large turbo on 4.3 amd 4.4 and don't seem to have much issues with tuning but when it gets into your car's era Ive never came across much.

No in fact it's simpler to tune less maps etc.

Those XDF's are simple map packs but seen to-do the job for you guys.

8000 maps in med9.1 or so iirc 4000 in me9 I had to modify over 100 maps iirc for my 5 bar file with code changes to boot. It just gets more complex per generation. MED17 is well difficult.

You're using a mastersystem (8 bit) new cars have an xbox one ecu to put it into perspective

What is a 5 bar file please?

[Dream3r]

ME7 is limited to controlling 2500 mBar of boost I modified it over 7 months to allow it to support 5 bar as a personal challenge.

It's the only one in existence for 2005 Volvo, their is one for 2004 and we collaborated a bit and found one issue in his file and he was happy with mine. It's the ECU that runs the 800BHP German one, so potential for a mega build was there, but decided B8 S4 was better lol. It was fun though, if you like reading binary and hex and assembly.

Obliterated my power target as well so job done move on.

It will take a bit of tuning for sure lol

I've managed to get the cams off and exposed more of the grey cappuccino water/oil mix underneath. Not great.

The progress continued and the head is now off. There is a split in the liner in cylinder 2. The piston crown is quite clearly washed out and a palpable crack is apparent.





I am going to clean up the head and get rid of the gunk - and get it tested.

As for the block - I have read about Colin's repair but I am still a bit dubious about reassembling on a clearly dodgy cylinder. So I can get another block and have it engineered for the wiseco oversized pistons (would new piston rings be needed?) - or go the more expensive route and buy a set of darton liners?

I am uncertain that the oily watery mess is caused by a split liner? So it may well be that both the head is cracked too. I am trying to remain positive.

[Wobbly Dave]

Looking at the cylinder 3 pic in this previous post http://www.vpcuk.org/forums/showthre...l=1#post755065 it is possible that the pot was already cracked at the top.

sorry to see the damage is this bad, I think is beyond the Colin fix as the split is outside the shimmed area, big jubilee clip or a new block in my book, man that must have been some boost spike WD, feel your pain but she will fly again..

[Jamest5r]

That's not good news mate

[Wobbly Dave]

So it looks like either the Darton route or new block (and get it shimmed properly this time). Which would be best?

[claymore]

I think the shimming was fine, I just think the split was already there , it looks a lot worse than my split liner so I think you need another block

[MoleT-5R]

I did see some talk about closing the deck, iirc Shem was able to do that but it did cost a bit.

is the block split on more than one cylinder dave ??

p.s only joking about jubilee clips

[stribo]

Wow, how much boost were you running to split a liner on a 2.3 block? How about a shimmed 2.4 block for the next build?
