get that kn filter kit and then it makes the dumpvalve real noisey

Why does everybody rave off the 4bar fuel regs? Surely they wont make that big of a difference unless your running a hell of a big power. Having one on a 150-230 horse polo won't really benefit anything spectacular and wont it just use more fuel? I think?

The 4 bar fpr is recquired for Revo stage 2, which is what most peole are going for. It's not so much raving about the 4 bar fpr, it's fitted along with stage 2 software and I think people are more raving bout the stage 2.

it's the diffrence between not getting past 220Hp and do reach 240Hp, in my case.
i also tried custom mapping it without the 4bar FPR but the car just won't get enough fuel and the injectors were running at max capacity.
so that is sorted out with higher fuel pressure.
even better is just get bigger injectors, but it's more expensive.
you won't make that much more Hp with injectors but it will be a tiny bit safer also.
better stick with 3bar, 4bar is more pressure, more pressure is more heat, and heat is the thing we don't want.
more heat = less power.
ok, i admit it's a tiny detail, but one thats important to remember

I like your reply. You've shed a little more light on my uneducated brain.

u mean the insulation under the bonnet??
also did that uit some time ago, it does make it sound good (i did it for weight savings but it's lighter as i thought it would be so pretty useless to remove it )

just watch the paint doenst suffer if you remove the insulation, the engine bay can get crazy hot and melt the paint off from the inside out.

Anyone done this and had a noticable differance. I run with the seal off and thats much louder than when its on

i have it removed for about 2 years now, never had any problems with heat.
and i've been on the nurburgring when it was 28C so i don't think it might form a problem, but a good point to look after, never know..!

I have just ordered a turbo intake pipe so that will be going on asap! My question is i have got all the mods to go for stage 2 but is the any point me forking out extra cash for bot much gain?? In not fussed about fuel or what not just dont want to build my hopes up and think its gunna be loads better when in reality it may not be!! Any opinion is helpful thanks chris

Have been riding on stage 2 Revo about 2 weeks and its awesome I cant tell you that! My friends call it monster polo! You mess with everyone up to 250hp at least!

Okey looks nice, but isnt supposed when having cone filter to put it inside the half OEM airbox to prevent heatsoak + PD160 ?

What about this guys? Anyone in here done it ? Works? What about Maf sensor position?
Looks like a bmc filter!
