1000HP+ FORD CONRODS - TECH
Atomic billet steel conrods were designed from scratch with one principle
in mind; use aerospace quality materials and sophisticated manufacturing
processes to produce an extremely strong, light and durable connecting rod
for the popular inline 6 cylinder Ford SOHC/DOHC engines, at an affordable
The Design and Evaluation Process
The Atomic engineering team set out to address these parameters by
designing what many performance engine builders are now calling the finest
conrod on the market for the Ford DOHC 6 cylinder engine.
Extensive CAD/CAM computer modelling was employed and produced a H-Beam
design, which has an extremely high stiffness-to-mass ratio. The next step
was to pick the correct materials, heat treatment and surface treatment
processes to ensure durability under rigorous performance applications.
Next came FEA modelling (Finite element analysis) to simulate stresses on
the conrods. This also entailed weighing every piston, gudgeon pin and ring
set on the market and loading this information, plus stroke, rotating and
reciprocating conrod values into our computer modelling software to
calculate the stresses.
The greatest load exerted on a conrod in an engine producing 600 comes not
from the force of normal combustion but from the tensile force exerted by
the piston at top dead centre (TDC). At 5250 RPM the piston exerts a
tensile load on the conrod of 1908 gs (-1693 kgs) at split overlap TDC
reversal. If you increase maximum engine speed by only 1000 RPM to 6250
RPM, the TDC tensile load rises by 50.4% to 2870 gs. At 7500 RPM the
tensile loading increases to 4132 gs, clearly demonstrating the Atomics
design strength of 8000 gs means it has plenty in reserve.
Excessive loads at TDC are brought about by a high reciprocating mass
and/or by increasing engine RPM, so it is essential to design reciprocating
engine components with the lowest mass possible to minimize premature lower
bearing shell bearing failure. This is particularly relevant to our
customers who are turning their engines to 7500RPM+.

The 450 HP Crawford Performance Turbo BRZ - /TUNED
We love the FRS and BRZ twins; they offer an approachable limit of
performance and phenomenal dynamics in an affordable package. And we
learned earlier this season that a bolt-on turbo kit will add to the FRS's performance
without taking away from it's character. But what happens when you double
the BRZ's horsepower and triple it's
torque? We find out.
Australia's Quickest BA XR6 Turbo
Phil Chain's XR6 turbo currently holds
the record with an 8.4 at 166mph, but the boys had some problems getting it
down the track at Jamboree and only (??) managed a couple of 9.1sec runs at
over 160mph. It's a beast of a thing with a massive GT47R turbo. How soon until we see a 7sec pass from an
XR6 turbo is Australia?
BA XR6T ute - [1000HP] Hits the Dyno at Palmyra.
I wouldn't be surprised if it did have 1000HP, it had wheelspin in every
run with the ABS kicking in aswell. Unfortunately I didn't manage to
capture it's 1/4 mile Pass, as my camera shit itself after this video.
Drag Crash - Stooge V8 Torana
Chris Theo was very lucky to escape unscathed from this unfortunate
accident at Heathcote Park. The very well built V8 powered Holden LX
hatchback Torana didn't fare so well.
