gary, pics of the bores please! I'll get some tonight if not tomorrow. From what I remember though, they all look good other than the mark on pot 1 that was visible before the strip down. In the 13's at last!.. Just |

Why not use this block, and get some 040 pistons instead of getting another block as in the other thread? On 13th Jul, 2012 Ben H said:

I would of thought they'd be equaly bad in pairs (inners/outers). Sounds like cylinder 4 hasn't been able to dissipate heat aswell as the others, if it is substantially worse? https://www.facebook.com/pages/Fusion-Fabri..._homepage_panel

Nope, I'm still using the heater plumbing. I left it there because of this the possible heat problems and cos I like it cosey in the cabin.

talking about buggerd pistons what do you think about this... They look like they have pretty much served a long stint in an engine, even excluding the huge ding in the bottom (dropped mabie) I wouldn't use them, I'd source a better condition set. I'm guessing they are standard bore, hense wanting to use them in that condition. Edited by minimole23 on 28th Oct, 2008. On 7th Oct, 2010 5haneJ said:

With regards to this, how have you plumbed it back in to your bottom hose? I'm using a front mounted radiator and have not yet got any of the hoses, I need to make an adapter for the bottom hose, to which the feed from the header tank will be connected to, will I need to do the same for the heater tap take off? I've been pondering about this for a while, wasn't sure if I really needed to keep the flow going past number 4 but I'd rather be safe than sorry!! Edited by richminiturbo. on 28th Oct, 2008. |

Right I've made a note of where the damage is on each piston and made a little diagram.  On 28th Aug, 2011 Kean said:

V - I've not done the calcs yet. Thing is, the pistons are running .8 mm down the bore. I was intending on getting them level with the deck. I assumed that this, plus the increased bore would take it up quite a way.

The piston sitting further down the bore would DEcrease the CR. 1/4 Mile 14.3secs 96Mph Terminal 10psi of boost.

if you go 040 and make the pistons sit flush you will end up with 9.19:1 CR. if you keep them 0.8 mm below the deck you will have a CR of 8.5:1 |

the difference in bore will make about 0.2-1 difference to the comp ratio,

Joe - that's weird?!? It must have worked at some point as Matty has made comment on it. I'll sort it in the morning. Nah ive never seen this pic either, I was just commenting on the first pic and the descriptions you've given about which one was worse. 
.....Unless the picture is supposed to be a red cross?

On 28th Oct, 2008 richminiturbo. said: The bottom hose for the rad has 2 return lines in it. I believe I took it from an SPI I was breaking could even have meen an MPI. But it allowed me to retain full control of my heater matrix and allow full unrestricted flow from around number 4 piston I had to fabricate the copper pipe and braze an extra piece on so I can run the system as I wanted hope the pic is clear.

You can see the two return lines coming out just behind the rad to the left of the cap. The copper pipe feeds into the lower pipe and the heater return feeds into the upper pipe wher I have positioned a later type heater tap. Edited by Mr Joshua on 29th Oct, 2008. Own the day
