Circa mid 200's, though drivability would be massively compromised over ITB's.

indeed, thinking about it if you increase capacity you could probably take it a fair way whilst retaining reasonable characteristics, but one would still wonder what if I had ITB's....

Hehe.
Dont jeveys have some longer inlet manifolds? On my bike bodied s16 a have a total inlet lenght at about 40cm and its very strong from the bottom. Its sound sick at 7500-8000. 141atw. Have contacted Miles for a better exhaust manifolds. l hate the cast one. l also have contact with Petert for a better inlet cam to get more out of the engine.
l love this Pugs. The only downside with the 306 is that its 250kg to heavy.
The last 20 years l ve only restored old british classics. l haved owned Austin healeys, Jaguar , Triumphs, but this pugs impress me.

Miles can sort you a Colin satchel DCOE pattern inlet to suit Jenveys, and an S16 4 branch exhaust manifold.

yep, they are 23mm and held in by a wire clip, RFS are 22mm and but press/shrink fit.

XU9J4 are 22mm slide fit+clip.

Big power cars on plenums are dogs to drive, the erratic airflow you get with such a large void behind one big throttle plate causes the mappers nightmares when trying to cope with transient throttle openings and low speed running is very badly affected. All or nothing is a phrase often used.
