Ok the good news car is running today. The bad news is throttle needs to be adjusted as something is binding as throttle needs hard push of idle. Then revs hard before freeing up to normal movement. It does mean car is un-driveable until this is sorted.  https://www.youtube.com/watch?v=vBJmKbeWsMY&feature=youtu.be

Throttle body made 21.7hp at rear wheels on old rolling road dyno. Car will be going onto original dyno Monday and will post overall increase with these mods . Seeing as different dyno used the only valid result is the 21.7hp from throttle body

After inspecting car today found new throttle has slight movement in the throttle shaft side ways. So I am thinking when vacuum is added throttle plate is moving side ways and jamming. So I need to find a way to stop this. Not very happy as its a new throttle body. >:( If that is not possible grinding small amount from throttle plate on both sides near shaft should fix catching . Just need to make sure not to much that I cannot compensate for with adjustment screw.

Ok First good news dyno run as can be seen was done. Bad news throttle issues meant they could not get a proper run in. As throttle is to abrupt in take up so I have been told they will redo when I fix the throttle issues. But you can relax I did get a result not as good as my 278.5hp on rolling road . And not the final reading as issues with throttle meant it was to easy to hit limiter and could not do full load run. But 255.6hp at rear wheels Torque 348.81 foot pounds . Flywheel corrected 320.8hp . So 31.9hp Flywheel and 25.5hp at the wheels but will update as soon as I can when I sort throttle problem.

Hi AFR was done on all runs it never went over 13.5 stayed mostly mid 12s . I have checked and re checked linkages even adjusted all slack that is not the problem. Throttle has no resistance with engine off it just goes to hell with engine on . Had to adjust idle up to make car driveable . Throttle needs hard push to start moving car then launches with sideways action and wheel spin. Under full throttle once moving its great. Try keeping speed even 100kmh it is on and off the throttle as light throttle causes throttle to close not pleasant. Been thinking its throttle plate jamming with shaft movement even though it was brand new throttle bought from VPW. Throttle pickup was changed from left side to right side with original linkage welded on to shaft removing cable pickup on left side. Been suggested throttle stop may be problem as had to add one on left side. Will investigate after next week as have legal issues to sort over next week taking up my days. Will let you know once fixed will redo dyno run.
