Dyno Day at Aldon|
Tip when attending a dyno session
would be wise to take and wear some earplugs; RV8s and BGTV8s on full chat (6,000
RPM) are surprisingly noisy in a concrete block building. What is also interesting
is the amount of noise emanating from the rear of the car, particularly the tyres
under load and the differential on all cars.
Pictured alongside is the
lovely 4.6 Litre RV8 belonging to Peter Jung. A full report will follow, when
we will reveal just how many horsepower this engine produced.
Nic Houslip reports "the V8 Register's
dyno day on Saturday 8th September at Aldon Automotive in Brierley Hill was interesting
and well attended. We had a line-up of RV8s and a single BGTV8 and everyone got
a run on the dynamometer. We will full publish details later, but two interesting
points emerged: one RV8 had a noticeably noisy engine when the bonnet was opened,
it sounded like tappets, but it's owner said the noise was from the injectors.
He had replaced them with set of aftermarket parts and the truth emerged when
the dyno indicated a measly 144BHP. He is going to get the old injectors refurbished.|
surprising was my RV8 - it produced 187 BHP from a standard engine with an Optimax
chip but the dyno man said he thought it was woolly at the top end, after checking
timing he discovered that the distributor was not advancing the spark as the speed
increased, so he suggested a trial, adding about 2 deg more static advance - and
lo and behold nearly 192 BHP. A distributor overhaul underway! "|
