Just to set the record straight...the only differences between my car and Tuomo's are as follows:
1. He has 3071 turbos and mine are 2871
2. He has a larger fuel pump with 60 lb injectors...I run 044 pump and 42 lb injectors
3. He has a larger fuel feed line with custom fuel damper system and mine is stock
4. He has E-boost 2 and I run Greddy Profec B
Other than these 4 items everything else is absolutely identical. All the parts came off the same fixtures, tubing sizes the same, etc., etc., etc.
I also built that 4.7 Euro S TT engine back in 2006. It's a shame it is held back with that old Callaway hardware. That car is easily worthy to make 500 RWHP since I set the compression at 8.1:1 and it has Nikasil bores and JE2618 pistons.
Truth be told, I've already seen 635 ft-lbs out of my car at 16 psig on the rollers. But right now I'm in the middle of completely re-gearing my business and building a brand new shop for this purpose alone. I don't have time to be toying with the manifold pressure on my car right now and it already will roll past just about anything on the road. I'm hoping for the wiring in my building to be done this weekend so I can get on with the final inspection and move onto "greener pastures". Tuomo left on a Sunday AM and that Monday I broke ground on the new shop and it's been busy as all get out ever since.
