Re: au engine question...
thanks fellas,so the ef,el xr8 and standard au all had e7te heads,but the au xr8 had the gt40 (or gt40p) heads,yeah, is that right?
if you get the e7te heads ported with 1.90 i,1.60 e valves and port matched etc etc it will flow good for mid range torque,i have found head flow comparisons charts on yank sites and they come up pretty good(if those articles are accurate.
if im going for say 200 kw flywheel power as long as those heads can support that then they are not a restriction,and you still get the good torque characteristics of the windsors
many years ago i ported a set of 289 heads myself on a bored 289 (.040 over) with an edelbrock performer,headers,10:1 comp 600 vac sec holley,280 deg kelford (n.z cam company) cam it had good power everywhere,low and mid range was impressive,so i figure the e7te heads must be ok unless you want big horse power numbers,say 220 kw or more
do any of you know off hand what the e7's can support when flowed.
if im looking at ported heads with bigger valves etc ,extractors,edelbrock performer manifold,1.72 roller rockers,bigger maf,bigger throttle body(70mm maf,70mm throttle body---- is it best to have the throttle body and maf same size or what,what is the go there fellas),cold air ,k+n,electric fan(s),from my research this sounds like a good everyday package,what do you think is there any area that i am off base or outright wrong.these e.f.i cars with computers are a fair bit different,but i want to become the full bottle on them.
with the above combo would i need to go to 24 lb injectors.
i want to keep the original cam if possible(the standard .444 lift cam with a 1.72 rocker has .478 lift at the valve.)
i like the idea of a sleeper like a standard au falc or fairmont,if i dont get an older xr8.
for what it is worth i set up a nos dry kit for someone on a commodore v8 e.f.i car as up to now i have only set up nos on carb engines,it has dropped 1.1 seconds off the 1/4.it is like adding 50 to 75 kw (flywheel),i would look at that on a falcon but keep the jetting conservative so a 50 kw boost sounds good
i want to set up my system so i can take it off the car with relative ease,as you know you cant have any nos components on the car in w.a on the street,i use to drive around with mine all there but with the bottle not hooked up,and thought i was ok,lucky for me i was not pulled over,so do your home work with any and all changes you do to a car,the cops looked at me a fair bit but i think they saw i was an old fella and wasnt doing anything blatant,so let it slide,even though it was obvious from the car idling at the lights that it was far from standard.
this time i dont want to have to worry(showing my age again),so apart from an intake manifold dont want to much to give the game away visually.
anyone know of any head porters etc that are good in perth.
my last engine was the first i didnt put together myself,and i got the kosteckis (total performance) to build it and was extremely happy with there professionalism etc
is there any others in the perth area that are windsor gurus or ford modification specialists,if so please let me know,
thanks for all your help and comments so far,it has been a great help.
