FD Uprated intercooler - suggestions please

[iaint]

As my injectors are currently peaking at 87% when tried on 0.9 bar I might get away with upping the I/C and, once mapped run them at 97% (for example).

This is way too close to the edge for my liking and, on a cold day may push them to the limits.  It only takes a second to throw a tip!

I\'m looking at a change to my intercooler setup (hopefully) but don\'t have cash to throw at it so I\'m hoping that I can either get some decent injectors at a bargain price or, preferably, get away with a bigger pump and a regulator.

Looks like I won\'t be able to reduce the running costs to < 1k per month this side of chrimbo!

Bottom line is what you can afford vs how lucky you feel!  Being unlucky is expensive!

You can up your fuel pressure and get ecu remapped and it will provide more fuel. Intercooler will flow loads more dense air whether front mount or vmount or stock mount and you will definitely hit 100%. Hitting 100% isn\'t going to do anthing to the fuel that would enhance the risk of detonation.
Theirs two kinds of 100% first is 100% but supplying enough fuel to maintain a good safe air/fuel ratio running like this for extended periods will heat the injector up and may cause injector failure. and the other type of 100% is when your at the max duty cycle but injectors are unable to cope with supplying enough fuel. therefore running lean and enhancing the risk of detonation.

Both sound like something to avoid.  Obviously best route is to do injectors and pump (along with remapping).  Anyone case to suggest sensible price for injectors and pump?

Yeah, I could. :p

Yep, running an Aquamist 1s system, with a 0.9mm nozzle at the moment. I already run low intake temps (30 degrees under load normally), but as soon as the water kicks in, the temps plummet!

I\'m running a pair of 1300 secondary injectors (for the time being), and even with fuel pressure upped by about 22% I\'m still seeing 80% injector duty at 0.8 bar.

Next project is Bosch 1600\'s.

Have you tried water injection? I had a home made kit on my TII and it worked well. It did add 2 to 3 psi of boost also.

30 degrees! What intercooler are u runing to get that low? or are you the only guy in antarctica with a Rex?

Max has an Apexi GT-spec front mount.
