Think you've been watching too many mad max films! What horsepower are you expecting?

I know how you feel I had to cut more holes in the bonnet to fit ST170, exhaust over the side and not through side panel and PX600 air filter for twin 45s. Looking good maybe next winters project....whats another hole in the bonnet.

Do you know what your Air Fuel Ratios will be?

Have you got a wide band o2 senser?

[tractor]

Yes got a wideband getting a steady 14.5 at idle and reving to 3500rpm it drops to 12 but this is just reving it on the driveway have yet to do a data log rain has stopped play

[tractor]

If I can make 220Bhp I would be happy with that

[Guest lotusPaul]

When you try it under load see if it gets to around 11, much more than that and youll be into bore wash territory.

 

Can you set a target AFR?

[tractor]

Yes I can set an AFR target

[Guest lotusPaul]

Im assuming you have capability for closed loop self learning?

 

Id target lamda for cruise and no more than 10.5-1 under boost.

If lamda is a little lean try 13.5.

All that work for only 90 bhp more than the pinto !
