Digsy Posted March 5, 2010 Share Posted March 5, 2010 Interesting? Heartbreaking is possibly a better word I was thinking that Nice one. Just wondering, is it a motored dyno (i.e. can the dyno turn the engine over)? If so, you could do proper friction measurements. Those combined with one of those AVL spark plug pressure sensors will probably tell you everything you would ever want to know about the engine on test.

RobSheffield Posted March 5, 2010 Share Posted March 5, 2010 Nice one Matt, i was hoping to engine dyno mine before it all goes back together, and the run in times would remove the stress for me too Quote Link to comment Share on other sites More sharing options...
Muffleman Posted March 6, 2010 Author Share Posted March 6, 2010 Interesting? Heartbreaking is possibly a better word Agreed Sorry, edit to say a superb purchase, the Jap tuning world needs to embrace proper engine dyno testing and mapping, it's like a dirty word at the moment. Average cost from the bigger players like Swindon Race Engines and Engine Developments is 900 to a grand plus per day, plus consumables and VAT. Should be a money earner, wish I could have one here but noise is such an issue these days. Have to be satisfied with one 4 miles up the road Shouldn't be anywhere as near as expensive here mate, we have the flywheel adaptor, spare loom etc so to install the 2JZ engine on the dyno shouldn't be a major drama. Makes it a lot easier if it's an engine you do regularly ! But without a doubt it's the best way to go. I know that Dave Walker says on the Emerald site that when they have been able to compare engine dyno figures (from other workshops) to "run down" flywheel figures for the same engine on the Emerald rolling road the results have been within a couple of BHP. I'm very keen to see the difference, I think it's great to calculate the losses on a rundown but in reality I'm not sure how accurate it can ever be given the factors going into the difference from flywheel to tyres, gearbox, diff, tyres etc etc etc. But I'll be finding out soon mate Quote Link to comment Share on other sites More sharing options...
hemmjonny Posted March 6, 2010 Share Posted March 6, 2010 is that my engine going on there? Quote Link to comment Share on other sites More sharing options...
CJ Posted March 6, 2010 Share Posted March 6, 2010 Congrats Matt. That does look an awesome bit of kit. Make me almost want to start all over again Quote Link to comment Share on other sites More sharing options...
