Captain Bondo Posted May 25, 2012 Report Share Posted May 25, 2012 Ive never seen a white block make HP on a dyno graph over 7000rpm no matter what it had done. Mine did when it had the T67 on it. Power was still climbing at 7500. 1 Quote Link to comment Share on other sites More sharing options...
ean carr Posted May 25, 2012 Report Share Posted May 25, 2012 hope you're replacing that piston, hot spots galore if not : sorry about the damage man, can only imagine how bummed / read to kill someone you were Quote Link to comment Share on other sites More sharing options...
dublin14 Posted May 25, 2012 Report Share Posted May 25, 2012 (edited) That looks like 9000 to me, and I think it still has some left in it... Actually I meant to say 7500rpm. But regardless.. with an HX60 I guess so ha! edit..Full spool at 6500rpm! Ive never seen anything bigger than a GT30 series turbo on a Volvo, 7500rpm was the point of no more pwr. I guess if massive amounts of lag are not an issue then its being done. Edited May 25, 2012 by dublin14 2 Quote Link to comment Share on other sites More sharing options...
boxpin Posted May 25, 2012 Report Share Posted May 25, 2012 There is lot of metal in there for just a valve breaking. You need to figure out where the rest came from. Is the bottom of the piston intact? I was thinking the same thing but I think that from him drilling/tapping Quote Link to comment Share on other sites More sharing options...
Jardim Posted May 25, 2012 Report Share Posted May 25, 2012 I dont know about you guys but i creamed myself hearing a 5 cyl @ 9,000 RPM. 2 Quote Link to comment Share on other sites More sharing options...
lookforjoe Posted May 26, 2012 Author Report Share Posted May 26, 2012 Busy day today I have removed the other nine intake valves & replaced them with Volvo branded valves from an '05 RNC head. Cut down the RNC cam cover to make a cam/valve setting tool. The Volvo (INA?) valves needed about .020" removed from the stem to achieve .010" clearance- much eaiser than messing around with the shim buckets. then put the valve springs in added baffles to the oil pan, like the S60R pan stock baffles back in place looked at doubling the pickup oring, from what I determined, it would push too far out of the seat, so I cut a second one in half and that was quite snug not too much lift on the hold down bottom end all back together 1 Quote Link to comment Share on other sites More sharing options...
lookforjoe Posted May 26, 2012 Author Report Share Posted May 26, 2012 Well that's a relief if it's just the valve. On a 90mm stroke there's not much point is exceeding 7600rpm. Regardless of the valve train the piston speeds go past the typically max 25m/s recommended for any sort of street car. Have you talked to southbend about a clutch? I am sure they'd sell you a 707 pressure plate with a custom disc. Then you could use with a "normal" flat flywheel - either a billet one with a 707 bolt pattern or a stock one with a redrill. Both the 707 and south bend have a good reputation. Mine was nowhere near slipping at 540whp/470ftlb The problem is just the disc to PP height (or depth) - I just have to add .050" to the PP seat areas & that will bring the depth to where it needs to be. Kalmar Union reckons that no DM flywheel is 9mm PP to disc depth, his supplier says all Volvo DM's are 7.75mm. However, 9mm is also the number that Spec specifies for their clutch and their flywheel is the same offset as the stock S60R. Pretty sure the SM clutches all have a smaller surface area than DM discs, and I'd rather not get involved with hybrid discs. BMac is having problems with South Bend - he is on his 3rd PP from them, and still not holding up under 11+psi boost on a Precision 58xx (don't remember the spec) turbo.... hope you're replacing that piston, hot spots galore if not : sorry about the damage man, can only imagine how bummed / read to kill someone you were Not replacing the piston, the rings lands are good - no binding - the damage is only to the crown. I cleaned up & smoothed out the grooves. Quote Link to comment Share on other sites More sharing options...
maciekb2002 Posted May 26, 2012 Report Share Posted May 26, 2012 so where did the metal shavings came from? I had similar gold mine issue , But one bearing was gone + second was almost gone!!! Quote Link to comment Share on other sites More sharing options...
lookforjoe Posted May 26, 2012 Author Report Share Posted May 26, 2012 so where did the metal shavings came from? I had similar gold mine issue , But one bearing was gone + second was almost gone!!! I don't know - all I can think of is that it was residual from the pan or the oil cooler - maybe I didn't flush them as thoroughly as everything else. There is definitely nothing at all wrong with anything other than the valve, so I could have just got away with pulling the head, but better safe than sorry.

Zappo Posted May 26, 2012 Report Share Posted May 26, 2012 You are an engine rebuilding machine! I should have sent you my engine. It is looking like I won't get it back for another month at this rate. 3 Quote Link to comment Share on other sites More sharing options...

lookforjoe Posted May 27, 2012 Author Report Share Posted May 27, 2012 little problem with flooding today - not the intermittent thunder showers in the forecast. Power went out around 3pm. Came back about 20min ago. The X1/9 had water up to the seat cushions. Most of it drained out when I parked it up the road on a hill, but I'll have to remove the seats & carpets to get the silt out So, didn't get much done on the engine except installed the head & misc stuff. Adam came by & helped torque the head - it's a PITA to single-handed angle torque on an engine stand. Quote Link to comment Share on other sites More sharing options...
