Hey Richard, I will be sorting out tyres on Monday as well as a few other issues.
On friday, I took the car up to RobK's workshop to show the car to him and run the car on the dyno next door to see what is happening with the car. The dyno run showed what I expect to be the case as far as power as well as confirming a few other issues.
The biggest issue being a hole (40mm across)in the reducer pipe which is located directly after the turbine. I discovered this today in the quest for problem solving. This is what was behind the car slowly finding its way to full boost at 4500 then dropping straight back off. At least I expect it was..Will pick up the new piping on Monday.
The exhaust also has problems being restricted by a damaged muffler which has now been removed with only the cannon fitted. Lost weight, decreased resistance, increased power and noise.
The dyno run also confirmed the knock sensor to be faulty as the car was running very VERY rich and timing retarted. I have a replacement coming monday.
So once all these issues are corrected I may see some more substancial output from the engine.
The dyno read 150.3KW. The best part of this being the performance of the car with this power level. So the only way is up.
So at 150kw, running in the brakes and not even understanding the car, I ran a 1.56. Wakefield it ran 69-70sec with a few quicker and slower with the wrong springs and 'standardish' brakes.
The Mr2 is really a great car to work with. To work on the car is painful at times, but ir really is a satisfying car and quick to boot! EVO65 always said 'He will gain great satisfaction from seeing the facce on the 'EVO' guys faces when they see the MR2 snapping at their heels'. Seems like this may very well happen friend.
