How long have you been working on it?
It's been about 7 1/2 years now....and I'm trying hard not to let it become 8 years. Life just keeps slowing it down.
I'm trying to sort out the exhaust now. The front headers still need the 2-1 collector and everything from there back, the rear set has the start of the 2-1 collect....4 of the 6 collectors ended up on curvers. The original plan was 750 to maybe 800hp so I planned 3" exhaust and have pair of borla XR-1 multicore mufflers which I knew would be too loud but....
Now dynomation is saying 940 is possible so that means 3.5" exhaust so I'm keeping the borlas and adding a pair of much quieter mufflers from these guys:
and vaccum cutout valves to turn of the borlas until I'm at least out of my development
The plan is to size the quiet mufflers for 250-300hp give control of the valves to the ECU and keep the engine quiet in all "normal" driving conditions. The engine should be crossing the 300hp point around 4000rpm but I'm expecting a bit of a dip around 3500 so I'm also curious to see if the dip is real and if the muffler helps any.
.....but I'm not exactly rolling in space to pack all this stuff that I never planned to have and still need to find room for air filters, oil tank and coolant line and oil filters and lines among other things
