Mik Posted August 11, 2005 Share Posted August 11, 2005 Hi guys,These chinese whispers are true... I was always expecting that I will need to attend to the 'weak point' of the car but no sooner than 6 months (I was hoping this anyway) Cause? could be a no. of things: - bad batch of fuel - overheating due to lack of capacity of standard radiator - blocked injector etc.... I was quite lucky to catch this out in its infancy, the compression dropped in cylinder 6 down to 79, othe 5 cylinders were reading a consistant 140+. As the engine is undergoing a total recondition with forged pistons, billet con rods, honing of cylinder bores, crank balance etc...my mechanic will be testing the other items for malfunction. I can't wait to have it run-in once again Marko. <{POST_SNAPBACK}> Ouch...was it pinging?

Marko R1 Posted August 11, 2005 Author Share Posted August 11, 2005 I have been advised ringland damage. It was breathing extremely heavy via the catch can. I am more than happy to build the bottom end that way I can rest easy & not worry about it when i blast it! What is the general consensus on these options considering the power I am running: - standard rods with arp bolts - forged rods - billet rods i guess if i do want to run race fuel i will need aftermarket rods, if i keep it on the street though with over 350awkw standard will be ok, thoughts???

But.......if i had my time over and could see the sort of development stage the car is at now i would go aftermarket....no longer just a road car....but back then it was.

Marko R1 Posted August 11, 2005 Author Share Posted August 11, 2005 Hi Paul & Stace, for the moment my car will be street driven with the vision of 'maybe' running it on race fuel (only once or twice) just to see what it is capable of...other than that it will be guzzling pump fuel! We run fully prepped stock rods in our car i.e. cryo treated, shot peened, closed and honed , ARP bolts etc. Rev the car to 9 grand and the engine has not missed a beat in 18 months.

Blitz Posted August 11, 2005 Share Posted August 11, 2005 Marko, as per my pm, I am going to be using standard RB26 conrods, prepared as per Pauls post above, with Tomei Rod bolts.

williamsf1 Posted September 9, 2005 Share Posted September 9, 2005 G'day Marko good to hear it is all back in 1 peice, for interest sake I did a power run at DART yesterday.... I have an overlay of the torque curves too and to all reading, I was on 19 psi and I think marko was on 13 psi.... so peak isnt really a factor but I made 585NM interesting to see where the RS Vs SS come on etc.. hope to see you soon, before I split to Adelaide... Im the green line....
