Average power?? thats for dyno comps.In real world,once u pass max power mark,you are going slower.Revving uselessly for no gain

no because reaction time.light triggers so by the time you shift,you are at about max Power.

Obviously then Various European car manufacturers have no idea then because they use 19". eg BMW M3,M5,AMG Mercedes,Jaguar etc. Gee even Ford are using optional 19"s on tornado and typhoon

I mean traction ,handling,and braking nproblems with 2 and 4 wheel drive cars.

Revs dont always = more power.A person of moderate intelligence would do a power run on a dyno,see where max.power is made and where it starts to fall away.Then purchase a shift light and then set it to trigger 3-400 rpm below peak power.Generally the majority are suprised to see where peak power is made.Usually well before this 8500 crap.

wouldnt organising a sealed air box with a pick up that drew clean fresh air be more beneficial than this "name brand" is SIKER than that one.I can only speak for what i have seen but we only ever ran K&N on the Willall car and now i do after a certain Jap.foam filters cost me a set of Turbos on mine.

If i had a 11 inch prong,id be in the porn industry.

Does it really matter unless you are a dyno queen?. Dyno shymo.When i last looked,a dyno is a tuning tool.If you go to the same dyno with the same(honest) tuner and correction factors are correct and there is no "X" factor input,who cares.Provided it reads consistently,it is a excellent tuning tool.However a whole industry has been built around the "my dad is tougher than yours and my shitter made more Kilowatts than yours".Hey book it in,lean it out,bang some timing in and look at the top end power increase (and overlay it over original power run graph).and they cant get the cash out fast enough.

no i was referring to original drag motor

all these recomendations.isnt it your car,its performance, usage,power and modifacations that will help your decision.What works on say a standard gts will kill you on a big HP gtr.

well you have never had a full twin from front pipes(TWIN 3") have you.I confess i did not have X-over pipe you recommed just two rear individual mufflers.Had the RB scream but with a gurgle.It could be heard 3KM away on a warm summers night Just north of Adelaide .keep that in mind "IF YOU HAD A GTR".SYstem for sale(800km old) as now have 90mm titanium.

ok.well do you have a twin system with or without a x-over pipe?

you dont know so why speculate. I do but cant be bothered.Its easier to let the crap,regular slander,uninformed and uneducated opinions blather away(some notable exceptions).
