fuel injection tuneing

[Andrew C280]

wondering if anyone has looked into putting bigger fuel injectors into there car and if it will make more Hp? also can replaceing the fuel presure regulator with a different one increase Hp? where is the fuel filter located ?

I've looked into going woth bigger injectors, but cannot find relevant information about my stock ones. Typically, if you upgraded you MAS, you can also use larger injectors to help with thte increased demand.

I'll look more into it and see what I can dig up.

The addition of larger, higher flowing injectors will not net you any Hp unless your current injectors are already max'ed out. Now if the newer injectors are capable of better atomization of the fuel then that may improve Hp.

An adjustable fuel regulator will typically not help you out unless you can set it at a higher fuel pressure to achieve better atomization and then can lean back the resulting over rich fuel mixture.

Read an article some time ago, whereas blueprinted ( exactly matched ) stock injectors can gain as much as 5 - 8 % horsepower.
Now THAT is a worthwhile investment. ;)

You can send your injectors to RC engineering as linked to above. I have worked with them in the past on fuel injected Superbikes and they do geat work and know thier stuff.

PS> WE often did pick up some Hp with higher fuel pressures with seemed to cause better fuel atomization and throttle response. But we had full control over the fuel and ignition timing curves.
