I can only speak for myself on the MR2. We do have a fair amount of dyno data, but (in my view) we still don't have a full title 100% IT build dyno sheet.
My personal view is the car is a 15% car. Others disagree, and without someone doing a balls to the walls full ECU tune, crank scraper, lightweight rings, exhaust dyno tested, Burns merge collector whole gee whiz shebang there will always be room for someone to legimitately say we should use the 25% default. I can't say their conclusion is outside the range of reason. I disagree with it, but I understand it.
I do not think (personally) the MR2 will get another look without the submission of new data. What that means (in my mind) is someone spends a LOT of dollars on an IT build, and is able to disclose to the ITAC exactly what they did.
This car is a poster child for what can go wrong with the Process, and it's a shame because it should be a mainstay of ITB.
Good thing that is what I just built (engine). I already have a custom built header for the car with the correct primaries length and diameter, and a tuned ECU.
I plan on very shortly remaking the header using the same lenghts as it matches what I did matmatically and was built on teh dyno by playing with adjusting lengths.
Tomorrow I am breaking the motor in under load. Hopefully sometime this next week I am bringing it to the dyno to tune it. Following that I am going to a HPDE test with spring and shock setups end of May.
I have an idea of what I will get, and hoping for 108hp, as that isteh current record. Which way does the ITAC like to receive dyno data? using different correction factors can really change the data. My personal preference is to have all correction factors off. If I owned a 985hp supra.. I would put a massive fan in front of the car, and change the correction factor to get it to 4 digits.
