Malpassi Fuel Pressure Reg

[Frosty]

Been told and looking for information on the MALPASSI FUEL PRESSURE REGULATORS

basically is anyone using these on turbo cars and what are the results?

my engine builder and tuner have strayed me away and told me not to use it as it stuffs around with your A?F ratios too much (ie. 3 runs on dyno same tune and 3 diff A/F ratios?)

can anyone confirm this and give me info and results if you have used them

Thanks

Well first question

Why do you want one?

Second

Do you need one?

[Frosty]

not running a surge tank at the moment and want one to keep pressure in the rail

Have useed them in the past to get more power out of standard injectors, the pressure has to be setupm as it isnt out of the box. There are three different models, 1:1, 1.7:1 and 2:1. no problems with varience on the dyno. i dont understand why do you need one?

[Frosty]

just dont want my car to run out of fuel/pressure

is it worth even running a reg?

im looking for options and opinions!!

Are you currently having fuel surge issues?

[unarmed_skyline]

i bought one cause i've just turboed my na and havent upgraded the injectors but a little extra pressure will make them flow a little better as i dont quite need to replace the injectors just yet, putting it on on friday when the car goes on the dyno. ill see how it goes.

[Frosty]

Nah but the motor is out and have custom rail and injectors so thought i would go reg to keep pressure in the rail

Are you currently having fuel surge issues?

UNARMED SKYLINE

look forward to an update on how you go with reg

[R31Nismoid]

Should have used the stock rail and purchased more beers down the pub

I would use the stock one personally.

Having done so with my surge tank setup and i never had an issue once it was done this way

[Frosty]

stock one is crapola

alwell someone else must have some info on this????

[R31Nismoid]

stock one is crapola

I call lies :sorcerer:

[Adriano]

why not get a set of stock det injectors, they would have to be worth sweet-f-all

[Frosty]

Stock injectors dont flow to what i wnt! Car will be making well in the 300rwkw mark

[Guilt-Toy]

Sard or better is the only way to go. Id never suggest a malpasi

[Adriano]

NA injectors and 300rwkw haha, hope you have got good pumps and 100+psi of fuel pressure.

[Frosty]

Adriano WTF are you on about??

no one said anything about N/A injectors..............

has a custom rail and sard 800cc injectors

clown

[unarmed_skyline]

i think he was refering the n/a injectors to my post earlier, and i didnt pick up stock injectors cause right now i dont need them for the car, im planning on upgrading the fuel rail 550ish injectors high flowed turbo cams bigger cooler and prob a head gasket in about 6 months and who knows what condish the second hand injectors are in at least i know mine are good and up to the task im asking of them right now

*thinks he should read up again*

using a rising rate and have no problem with it, except the noise it makes when fuel first hits it but that is normal.
