Coastr Posted 1January, 2019 Report Share Posted 1January, 2019 but what about the red shroud? I reckon a bit of refinishing would be great Quote Link to comment Share on other sites More sharing options...

Mike D'Silva Posted 19January, 2019 Author Report Share Posted 19January, 2019 I think that output at the wheels is OK. Dynos are subjective.. only good for comparisons on the same engine. To give it some sort of perspective, a stock Toyota 86, which is supposed to have 200hp at the engine, puts down 150-160hp on this dyno.

bumble Posted 21January, 2019 Report Share Posted 21January, 2019 Very impressive - that torque 'curve' is fantastic. The Porsche club uses a 32% loss factor to convert dyno RWP to crankshaft power which by my reckoning would give you close to 280hp at the crank. The same calculation would give your Toyota 86 close to 200hp. Well done... Correction - missed the 168.9 curve. Make that an even 300hp!

Mike D'Silva Posted 21January, 2019 Author Report Share Posted 21January, 2019 Yeah, I dunno.. seeing numbers like that makes me feel all warm and fuzzy, but I'm probably never going to rev it that high anyway. It does feel strong though Just waiting for my other gearbox to come back from being reassembled.. in the mean time, just putting some more miles on it to get, then will pull it and do an engine out service, valve check and swap boxes over. Then back in for the long haul... Cheshire Cat and firstone 2 Quote Link to comment Share on other sites More sharing options...

Coastr Posted 22January, 2019 Report Share Posted 22January, 2019 Did you get video of the dyno run? The car will be faster than a stock 930 now. firstone 1 Quote Link to comment Share on other sites More sharing options...

Seems to be completely random. Sensor is bolted on firmly and it is a genuine bosch. Ideas? Quote Link to comment Share on other sites More sharing options...

Could be a number of things but often on ITB it is small vibration of the butterfly shaft wearing out the idle spot on the sensors resistive track. You need to make sure that there is absolutely no movement of the shaft at the sensor when idling. Using a contactless sensor is a good idea for ITB. This of course assumes you don’t already have a contactless TP sensor. Cheers Quote Link to comment Share on other sites More sharing options...

Cheers Thanks for chiming in.. no I do not have a contactless TPS at this stage.. but have just purchased one and will aim to get it mounted this weekend. Did mine wear a spot on the resistive track? It is not very old and the car has only travelled maybe 1000 kms total with the itbs... Or maybe I got a faulty sensor that didn't last long? Either way, no point messing about.. without an accurate tps, I think data logging is pretty pointless. Of course, I have it mounted at the bank of cylinder 3, so removing and re-fitting will involve mirrors, double joints, dropped bolts, magnets and cursing.

Peter M Posted 22January, 2019 Report Share Posted 22January, 2019 Mike, Could it be that there is not enough free play in the throttle cable and the throttle is not always closing on to the throttle stop? firstone 1 Quote Link to comment Share on other sites More sharing options...

Peter M Posted 23January, 2019 Report Share Posted 23January, 2019 Or, the tps isn’t a snug fit on the end of the throttle shaft. This would also result in the WOT signal varying as well. Quote Link to comment Share on other sites More sharing options...

This would also result in the WOT signal varying as well. Not normally an issue as the TPS is (should be) spring loaded against the shaft to effectively remove all play.
