190lph limits

[lq1driver]

hey im just finishing up my winter project and realized im still on my 190lph fuel pump. what i need to know is with my base fuel pressure being 43 psi with 25 lbs of boost on 750cc injectors will the 190lph be able to supply the fuel im lookin at 68psi under boost.

It may on a b16g, if rewired, i would probably upgrade for piece of mind though.

This thread should give you an idea of what you can support. It looks like you'll be on the ragged edge with a rewired 190lph.

ehhhh, your profile says b16g, so unless you let us know otherwise, thats what we'll assume you're talking about

sorry havent update my profile in a while set up is frank 4 lookin to run about 22-25psi keepin the idc at around 80% on 94 octane

If you don't want to buy a higher flowing pump, than you may just have to see what your idc's are at the time, its hard to say, but will be cutting it close for sure

Fuel pump rewire for sure. I'm running a Denso 150 LPH with rewire on 660cc injectors with 44 lb/min of measured compressor flow. It was dicey a while back without the rewire but it holds fine now.
