Just been to John Clarkson of Chorley , Lancs for power runs in my Eunos 1.6 Turbo
http://www.johnclarksonautos.com
Met with Andrew - great bloke and does a good job.
Did 5 power runs, looked in between runs for issues to correct, made adjustments to MBC and wastegate actuator.
Upshot was 266 bhp and 226 lbft torque at 16 psi, thought this was a bit too much boost as I dont know whether internals are stock or modded so reduced to 13 psi.
Spent 2.5 hours on rolling road, full printouts boost AFR, duty cycle, power , torque - cost 90 quid.
Printout showed accurately where I am over rich above 4,500 r.p.m AFR approx 10.5.. have now adjusted i'j map duty cycles.
Also boost was showing drop of 2 psi at 3500 rpm then buld up to it's peak at 5500 rpm. need to investigate whether this is due to Manual Boost controller if so looks like upgrade to electronic boost controller. Andrew said first reduce iridium plug gaps down to 0.6 mm currently 0.8 mm to eliminate possibility of spark being quenched due to boost conditions( evo owners run 0.6mm)
Also duty cycle charts showed spikes on a generally linear plot around 4500 rpm and up instead of steady linear plot. Andrew said ecu not liking injectors somehow (550 cc),
anyone else had this issue ?????
Still car drives great and goes like a train
Highly recommended....great bloke , top equipment
You wont be disappointed
