Lewis's Datsun 1600 NEW PICTURES!!!

[lewishorrell]

yea it sure does still got to iron out a dead spot when rapid throttle is used eg slamming ya foot down straight away but that is just bigger pump jets and it should be sorted then up goes the psi im thinking 5psi should be enough

[Bartman]

im thinking 6psi should be enough

[dirtyleppa]

im thinking i should have got a turbo so i can wind in more than 5psi, and stop being a sissy

[lewishorrell]

nah turbo for kids im thinking bart what size pully will i need for 6psi ill have to get bigger carb cos the one i have is at its limit i think still needs more fuel at top end and on acceleration

[Bartman]

what size pulleys are you running now? Given your engine is the same displacement as the engine the blower was fitted to factory, it would be safe to assume that similar drive ratios would yeild similar boost numbers.*
(*depending on camshaft specs, and head flow characteristics)

[lewishorrell]

its running 1:1 at the mo so maybe a lil bigger will be good it goes hard atm and doesnt seem to be playing up im almost considering leaving it for now until i get a L18 cos the compression ratio on my wee L16 is pretty up there got to be careful.

[Bartman]

If you're going to change engines, I'd strongly reccommend a blower friendly (and lumpy!) cam grind, as well as using an L20B head. (they roll quite a big port, and can't hurt your CR either.
