mark newman Posted May 10, 2013 Author Share Posted May 10, 2013 Not a good day at the dyno yesterday my engine let go, the engine was making good power it was making 1075bhp at only 1.9 bar at the hubs and sounded great ,so I was thinking I would have a good weekend of racing at the pod. but when we turned on the nos after two runs this happened , oh well, we think the end of a spark plug came of , but we wont know untill I take the engine out and strip it out , So it looks like I will start rebuilding again. cant wait to hear this turbo set up start again .

mark newman Posted May 10, 2013 Author Share Posted May 10, 2013 Thanks for the support guys . but when you put that much power through an engine its going to go pop sometime, but would of been nice to do some racing first , oh well I started tonight stripping the engine it seems that the turbo is ok as nothing has gone through it , but there is grity oil in the oil drain , so it will have to be cleaned out or the bearing replaced, I think that i have cleaned it all out and the turbo spins nice again, so thats a result . I have started planing my new build , and going through the parts I need , will be looking for a block, pistons, rods, billet main caps, mybe a stock crank.

JamieP Posted May 29, 2013 Share Posted May 29, 2013 Make sure you give everything a good clean mate, I'd junk any oil coolers if you have them, good luck today Quote Link to comment Share on other sites More sharing options...
Luxluc Posted May 29, 2013 Share Posted May 29, 2013 Nice spec list. What were the engine head specifications you have been running? Quote Link to comment Share on other sites More sharing options...
mark newman Posted May 29, 2013 Author Share Posted May 29, 2013 Nice spec list. What were the engine head specifications you have been running? it was a stock head with 1mm over size valves with 280 cams . Quote Link to comment Share on other sites More sharing options...
Luxluc Posted May 29, 2013 Share Posted May 29, 2013 it was a stock head with 1mm over size valves with 280 cams . Are you considering porting of the head? Quote Link to comment Share on other sites More sharing options...
mplavery Posted May 29, 2013 Share Posted May 29, 2013 Just seen your video Mark ... Terrible news mate Sounded frekin awesome before it went though !!! Hope everything goes well with your new engine Quote Link to comment Share on other sites More sharing options...
mark newman Posted May 29, 2013 Author Share Posted May 29, 2013 Are you considering porting of the head? no not yet , paul is sorting my head out , for me but it did make good power on stock about 1400 bhp then bang. I dont think porting would have stoped that. Quote Link to comment Share on other sites More sharing options...
Kaan W Posted May 29, 2013 Share Posted May 29, 2013 Did you have 9:1 pistons before Mark? Whats the reason for going with this CR over stock? Quote Link to comment Share on other sites More sharing options...
mark newman Posted May 29, 2013 Author Share Posted May 29, 2013 not sure what you mean. Quote Link to comment Share on other sites More sharing options...
Kaan W Posted May 29, 2013 Share Posted May 29, 2013 not sure what you mean. Why are you going with 9:1 compression ratio pistons when your running crazy boost and nitrous on pump fuel? I was always under the impression you need to run 8.5:1 on nitrous engines unless your running strictly E85. Quote Link to comment Share on other sites More sharing options...
JamieP Posted May 29, 2013 Share Posted May 29, 2013 The high compression is a good choice imo, especially as mark plans to run race fuel, I ran a high comp engine in my supra and have done the same in my GTR, even on pump fuel there was no issue, I still managed big power at 2.6 bar on vpower.

Kaan W Posted May 29, 2013 Share Posted May 29, 2013 Thats some serious boost for that CR on pump. Im unsure what to use for my build now as ive been told to stay with stock CR. Quote Link to comment Share on other sites More sharing options...
mark newman Posted May 30, 2013 Author Share Posted May 30, 2013 It should be better for spooling my 88 mm turbo , so I might not have to use nos untill I get this engine settled in for a bit, It has been really hard starting all over again after it was all finished ready to race the next day , now I have got is lots of bits , and nuts and bolts all over the house, garage. car transporter , and in the car , what a mess I hope I don't forget how to put it all back, and it runs first time .
