It will be interesting to see what the A14 will make. Forged pistons and stronger rods do not make more power.

The power limiter is the cylinder head. Naturally aspirated they max out about 200hp, but that is with radical porting. The only way to make more is to pressurize the engine (18 lbs boost is a lot, over two atmospheres). That will generate a lot of heat in the port, even when an intercooler is used. Lots of fuel (rich mixture) and high-octane fuel is required to prevent detonation.

that's crazy but I can believe it like my dad said "it's not the car that makes u win it's the drivers' hart that runs the car"

it not that simple...
a lot of work has been done to get it to this stage...
fuel injection with a good tune is the key
he was maxxing out the 330 cc injectors so got some 440cc on friday...
then went for a final tune before the dyno comp...
it has perfect a/f ratios all the way through the rev range with a liitle bit of fattness up the top...

faaaaark I don't think I am making half as much power with my built A15, I am guessing that the secret of the power was in the tuning of the fuel injection, spark timing and intercooling?
definately load pics and vid this I gotta see!

thats around 170rwkw isnt it? I am going out to the shed right now and starting to fit my turbs and wind up the boost

PICS PICS PICS
oh and movies

atw..... means at the wheels...

Te fuel was bp ultimate...

i guess i will have to host that video and pics i was talking about....

also it was friggin hot as well....

a rb25 r33 only made 215hp
s15 with sr20det made 260hp with massive turbo...
then a ca18 ke70 made 307hp

is that 240hp at the treads?? With only 18psi??? out of a stock A12!! Man i want to see that.
Not saying its not possible but I still find it pretty hard to believe.
What kind of fuel was he running??
Cheers Andrew

Can u belive this????
my mate was meant to have his a14 ready for the rebels dyno comp in QLD but could not get it done in time...
he had to settle with the stock old smokey a12 bottom end with some really schmick bolt ons....small amount of headwork custom valves, custom plenum and exhaust manifolds, s15 t28 bb, microtec, 3 1/2" stainless exaust with screamer, bosch coilpacks and a stock a12 bottom end,
stock sedan diff,
stock 60series gearbox

running 240hp @18psi...
pics and video footage to prove it...
now stick that in ur CA pipe and smoke it....

funnny thing is the new a14 engine will be ready in about 2 weeks.... and way more power can be made... it has forged pistons fully balanced and blueprinted block... and planing to be running in excess of 20psi .....

big clap to all the boys at Headworx @ Yatala for giving me back some faith in the old a series power...
