hmm decat?

[m1tch]

really? Woohoo. Lol

Maxing out injectors (ie running them above about 92%) will then make it fuel at 1/2 the amount cause the injectors can\'t keep up....so the engine will run lean at the high RPM....which is very bad lol

[Nik da Greek]

not by much if all your doing is decatting her surely.

A de-cat and filters without an aftermarket ECU or some upgraded means of boost control will likely shorten the life of a good few components, the engine not least! You\'ll get boost spikes all over the place and really lean bits of fuelling just when you want them the least. Not nice, especially when it goes off like a grenade! Really best not to play roulette and upgrade the control systems as well as the breathing

[m1tch]

Uprate all the safety mods like HT leads, fuel pump, ECU and injectors before you start pushing stock systems Don\'t forget to uprate the brakes and tyres before you increase the power as well

ive got a decat with k&n induction kits but also got an apexi ecu and controller, im running it on the lower boost setting, is this a safer option? just out of curousity too for those who have the apexi ecu what should the knock setting peak at usually? and what should the injector rate be to? i know its different for every car but would be interesting to see what the range should be, the only performance mods ive got are a blitz dv, k&n induction kit decat pipe and catback exhasut (so full exhaust off the downpipe) and an apexi ecu and controller running on the lower boost setting

[Gatesy]

I\'m running HKS filters with a decat and an Apexi on mine and she runs fine.  Shoots flames when warm but is great great fun :-)

[Cooch]

Thats what i like to hear! Cant wait. Lol

[Gatesy]

Just remember that they recomend you change the hks sponge filters every 5k-6k miles.

[gandyRX]

are apexi filters any good? i love the fact mine shoots flames not entirely sure if its a good thing or a bad thing though

[michaelb]

lol thats mad!! i love rex\'s!! and hey i didnt know you can get k&n\'s for the rex?! are they actually made for the car or just 2 universal ones?cheeky but any chance of a pic? please? :god  so for about 700 i can squeeze a fair ammount out of the rex? will it run an extra 100bhp safely? not forgetting that standard its 280ish i think?
 
cheers for the replies guys im now >>> :chat

Hello mate

I have a 96 RB Bathurst, HKS Super dragger, de cat, Apexi, HKS Racing Suction Kit ( new £380 ), ported engine, boost up by 0.5% and 350BHP on a twin turbo set up.

The day you fit a de cat and fir an Apexi with a modified map you will defo feel more  power, the only way I could describe it is as if you were driving around with a passenger and then with out one, that is how much more powerfull and lighter the car feels..

Regards
Michaelb

You would be daft not to go decat really. On a 93 plate, you\'ll pass the emissions with a bit of adjustment to the pfc. If you can get away with not having one, then go for it. You\'ll pop some nice flames too, and you can sell your old cat to the scrap man for 50 notes.

[NurburgRob]

I\'ve just got an Apexi and will be decatting soon, with standard fuelling, ignition and intake I\'m happy to stick to a safe 300bhp at the flywheel until the other stuff is sorted, that\'s still an approx. 40+bhp increase on standard.

What? where? never knew this!
