12p blown 355
Thought id start a thread for this vn ive been working on
Its a Tidy vn with a 355 thats got a side mount supercharger blowing in about 8psi, only recently got a chance to do a half decent tune on it and spent hours doing it First thing i did was check timing, at least i was going to... the bloke and my old man were looking as i bridged the pins and said it was 10'. trying to do a bit of road tunning and it just wouldnt rev with a bit of boost, had about 15' in under boost and good afr but wouldnt play the game. started throwing timing at it and by 28 under boost it was going ok no knock i knew something wasnt right.
Rechecked timing myself and at commanded 24' it was on 10' of advance...
with that fixed i then found an injector not working, wire had pulled out of the plug so it was only connecting occasionally
we managed to get a rough tune in till we get a chance to finish it off but its pretty wild so far, getting hard to tune on the road haha

no project is without its hurdles!
a n/a 355 is hard enough to tune on the street without a blower!

No matter what the question is, the answer is always more horsepower!
