Need Advice On Pressure

[LINE26]

hello. I write to you from Russia.

one I have skyline r33 rb25det 1995.

specs:

piston gt-r

ear ACL

laying stock

greddy intercooler

pump n1

fuel pump nismo

720cc injectors

stock intake manifold

turbine kinugawa td06-25g

processor apex power fc

maf z32

full exhaust

and much more on the little things.

please tell me?

The pressure is 15 psi, how much can you max pressure to do? without damage to the motor.

thanks in advance.

Do you have a tunable computer ecu? If so you need to find a dyno tuner that can increase the boost while monitoring the afr to ensure no damage to the engine. If not its very hard to say but for short periods 18 psi should be ok but hopefully someone else will have more info for you.

That turbo should be able to do 18 - 20 psi fairly easily. The Z32 should be able to measure that much air. The PowerFC will allow you to tune it to suit.

It just has to be done on a dyno, as mentioned above.

Thank you very much for your answers.

I have a custom computer apexi power fc.

with dyno in our town a big problem, we just do not have it.

machine set up on the go, riding on the road

mixture of a / f control aem uego, as well as the whole range of sensors is defi.

turns out I have understood correctly, with the right settings, I can not do damage to the engine 18-20 psi???

[portaz]

As long as ur watching the mixtures it will be fine just take it easy like go up 1 psi at a time

[LINE26]

not quite sure, because I have difficulty with the translation.

you mean to ride on the road is gradually adjusting to 1psi???

Start at 15 psi, do a run. Watch the mixtures.

All good? Add 1 psi. Now 16 psi.

Repeat. Tune as required.

[portaz]

Yes road is fine as long as your careful

Thank you very much for your advice, I'll build up to 18psi.

Please tell me what you think gash stock injectors?

Stupid idea. Do not do. The days of destroying injectors like that are gone.

Good big injectors are cheap these days.

not real good but is a cheap and popular highflow route, fine for power but idle and fuel consumption is generally compromised.

these are available on ebay as various brands.
