So played on and off today with the NA on the dyno. First baselined it a few runs. This setup is dead repeatable.
After that fitted my 70mm Throttle body. (Robbed it off the drag car) 5 min swap with coolant deleted. Picked up a good 5whp across the board! Then fitted the B202 86-90 camshafts to the same timing as before. Lost all we gained. So then set off on a fishing expedition with cam timing. Swapped it a few times, You can see we ended in the mid 30s for dyno runs!
So all in all 145 whp is quite a ways in on the 2.3i but with the short 4.45 gears and the instant response the extra 10-20 whp up top should make it a blast to drive. Very excited to see how the new head helps. Might even try a sports exhaust instead of this vig original.
