Increasing Boost And Increasing Fuel

[vladinator]

Hi,

I have GTS-t r33, I am thinking of getting HDI electronic boost controller, and getting it boosted up to 10psi.

Because the ceramic turbo cant handle very high boost I prob wont set it higher.

I have been told though by a mechanic that increasing any boost I have to increase the amount of fuel going into the car.

He told me if I dont car might detonate and the injectors will fry?

Is this true?

I have 3'' exhaust turbo back pod filter atm.

Also Can I increase the amount of fuel with a fuel pressure regulator?

If so why would I bother getting after market computer?

increasing the fuel isnt necessary in the skylines on the stock computer, the computer will allow for this. the more air being passed through (+ boost) the more air the afm will read -> the more fuel the computer will add. you wont need to worry about any kind of engine management if you're only running 10psi on the stock turbo. if you want more power/economy thats when you'll be wanting to fit one.

what you'll actually come to realise is that you'll actually be needing to take fuel AWAY from the mix

so whats the difference between FPR and after market ECU?

[SECURITY]

fpr lets you increase the fuel pressure in the fuel system, which will allow you to scrape a few extra kw out of your standard injectors but will be running them at over 100% of their capacity which is a bit dangerous.

ecu will let you control things like amount of fuel in the injector pulse and timing. it doesnt only do fuel mix and it does not control fuel pressure.

hey thanks

Igot 1 more question?

you think I should bother with electronic boost controller?

or just get manual boost controller if Im going to run only 10psi?

Just get a manual one and leave it on 10psi. ^^^^^^^^

Its your right foot that controls the boost.

[SECURITY]

if you're planning to run over 10psi in the future i'd recommend getting an ebc if you can afford it. but then again, im running 14psi on an mbc.

if you were going to get a manual boost controller i'd only go for a turbotech boost controller. probably the most reliable mbc ive ever seen.

but you're getting more airflow at WOT, and you cant control boost with your foot to the floor.

Well foot to the floor would be 10psi.
