The thread contains setup(technical) and dynosheet + explenation, aka what went wrong, what could have given more, or what did the good results.
First of I want to put up the stock numbers the respective bonestock engines put out on our dyno.
As you may know the dynapack is attached to the hubs and meashure shaftoutput aka WHP so the noumbers are way lower than engine BHP-
Mazda 6 152hp: 96whp (depends on condition)
peugeot 307, 176hp(130kw): 98whp (depends on condition)
d15z6: 83whp (depends on condition)
d16z6: 98whp (depends on condition)
b16a1:115-120whp (depends on condition)
b16a2:120-125whp (depends on condition)
b18c6:148whp (depends on condition)
b18 typeR: 150-160whp (depends on condition)
First post:
Civic with 81,5x89 c1 block, b18c5 head stage 2 port
stock cast iron manifold, and cat. 153whp with oem ITR camshaft 160whp with S2stg1 camshaft
The engine would have seen 180-185 with a hytec replica tubular manifold instead of the cast one(seen on the b16a2) and the stock cat.
Ive seen as much as 30whp increase from a H/E upgrade.
But 160whp on stock exhaust WITH cat is good. The engine suffered from high exhaust back presshure, you could see it when the vtec engaged and the Intake flow velocity /presshure dropped while the exhaust presshure stayed the same, (dip in curve)
