it will be a new converter, it will be Neal Chance 100% instead of a Neal Chance/TCE hybrid, we think that is letting us down a little bit now. yeah, n Vince is a whiz with the 8860, there is noone better with it then him, so hopefully it's all win win.Going up 2 points will make heaps of difference !! IMO
Get up on converter even faster !! Off boost also !! No down side the tuner knows his way around an 8860
I guess anyone wondering how much power 1.5" primaries can support on this V8 turbo? Well, at least 1200hp... And you intend to use these for your 1500hp target? Fits in with one school of thought that suggests the turbine and housing are more restrictive than the primaries so they are rarely the choke point.thanks. they have a .065'' wall so if my maths is correct 1.37''
it could definitely be made alot more efficient, Kyle had a little look at the exhaust manifolds a lil while back, he said it works, so that's the main thing no real thought went into them, they were just knocked up quick so the car could be engineered, then a new set would be made. these worked well so we ended up keeping them.I would say the merge or collector could be better ?? Helps spool with large-sh turbo'd and takes advantage of any pulse at low-sh rpm .. Diamond shape inside collector keeps velocity of each cylinder ! My friend made his up this way on another 4.0 engine !! Trouble is we tend to do other mods at the same time !! Not easy to compare ? But going to larger turbo and spool is about the same if not quicker !! Had these discussions with Kyle ( 6 boost) years ago .. They make good manifolds .. $$ ..
