is it safe to run 1.2 bar with standard ecu and no chip..200sx
 

200sx s14a

currently not even holding 0.9 bar but gonna get that sorted.

would it be dangerous for the engine tho?

got a few mods including upated fuel pump?

whats the deal?

I wouldnt, When I turn up the boost on road S14s I usually dont go any more than 0.9 bar maybe 1 Bar max. And with that I always fit an adjustable fuel actuator to turn up the fuel pressure a bit.

as above 1 bar max even at a bar I would feel uneasy without having it checked.

Not particularly wise.

'Under pressure' article in this case.

Speak to Horsham Developments..

probably gonna get it booked in with horsham in the coming weeks!

anyone else got any views?

always like reading stu's technical articles in FF!

ideally i would want to go to MSD as his knowledge seems endless! bit of a treck from london tho :(

wheres all the tech experts?

was hoping for answers.... :cry:

Well it depends!

You need to get your fueling checked... many places can do that for you - where are you?

1.2 bar is stretching the standard T28 to its limits, 1 bar is much safer. Also its worth noting that at this level of boost (1 bar), the standard "yellow" injectors will be maxed out above 6k rpm ish anyway :sad:

standard fuel pressure would be ok but an uprated pump, such as the common walbro 255 fuel pump is a must really :king:

london mate... west london if that makes a difference

already got the walbro pump dude ;)

spec is in me first post... well the pump is... :)
