OK.So far to stock car have added filter and exhaust(cat back)and stats are: 182bhp & 131ft/lb.
Car is now de-catted by fitting Spoon 2:1
Dynopack:Yellow boxes= Filter + Mugen Twin Loop Cat Back
Green boxes= filter + mugen twin loop cat back + Spoon 2:1
(note torque figs are for bottom end as it stays approx same at top,131ish)
This one shows figs for stock car v todays results:
The intake temp was within 1degF to standard and fuelling is now a little bit leaner*.
So losing the cat adds about 5hp at the hubs and in combo with the Mugen twin loop it kept the torque
So car figures at 187hp at the hubs and 131ft/lb
Yells its head off now as well-but not too loud for track(fingers x'd)
Done 70+ miles with no engine checklight(*might help this a little).
