finally after all this time I had to replace the standard xhaust wich I might add did a good job with a better one I had lochy have a look at the tune when he was in adelaide the other day and managed to get the power up 40kws through the rev range and some more up top but time was not on his side so today I took it too another dyno I use and squeezed some out of her 368RWKWS (493.4rwhp)looks like a few more mods needed to get her over the 500rwhp mark

That's good power. Is that with a Nizpro stage 2, or have you had the internals strengthened?

Brian

stage 1 with my own injectors and other mods as well and the engine is stock apart from the valve springs going to do the rods shortly and maybe some head mods

Those figures sound impressive

Those figures sound impressive

yeah very impressive considering it's a stage ONE nizpro kit (plus injectors)!!!!

makes the APS kits look pretty weak in comparison

here is the dyno sheet

I am confused, so the standard exhaust was good for over 300rwkw? :roll:

How many rwkw have you had your T up to with the standard exhaust?

Or is it the aftermarket one you have has reached it's limits?

Just interested as I am told my exhaust is restricting a fair bit of output, which I can hear it struggling sometimes, sounds like it's pushing out a potato

Under load pushing it hard say in 3rd through a sweeping corner it bulds up the gases and struggles to push it out, it basically goes bang!

Any imput would be appreciated

JB,

I'm sure Badxr6 had a stock exhaust until now....

Even mine has run well over 300 with the stock system Dyno'd with the first APS PH II typhoon last week and had more atw that the Phoon had

Badxr6

Well done, great results so far ! I can see you reaching the 500+ RWHP soon ! Or is that 600RWHP I can see coming up ?????

Pretzel

How much boost are you running to get such high HP?
