The basics:
Autech tuned Pulsar, manufactured in 1996, imported to the UK in 2006
High port engine, advanced timing, sports tuned ecu, high lift sodium filled valves etc.
Totally 'standard' Autech, no modifications. 63,000 miles on the clock, no rust
According to Wikipedia:
''Autech Version SR20DE — 1998 cc DOHC multi-point EFI. Only Sold locally in Japan. Was used in Serie and Lucino Japanese Variants (576 produced total). Featured compression ratio of 11.5:1, 264 duration @ 11.4 mm lift camshafts, unique valve springs, DET vales, portwork, piston oil squirters and unique pistons to achieve high compression. Power is stated at 180 bhp/130 kW @ flywheel. 191 nm@4800rpm.'' (Happy for anyone to correct/improve on this info')
Today: Racing Line Halifax for Diagnostic Power Run on Dyno Dynamics setup.
Blue lines are before Matt got under the bonnet for a bit of tweaking on the timing and the red lines are the final runs.
Before: Power at wheels = 123.7 HP, Power at Flywheel = 150.8 HP
After: Power at wheels = 141.4 HP, Power at Flywheel = 171.2 HP (The best £80 I've ever spent on a car!!!)
Note the lag followed by a peak at 3100 rpm before adjustment (blue) and the linear power delivery after adjustment (red)
Heres the final run. Matt reckons there may be a wee bit of cam chain stretch, that could get it higher, but not really worth the effort just yet to replace it.
Other feedback was that the ecu, electronic etc. were working perfectly. There is hardly any vacuum effect even at 7500 rpm (dotted red line below) and so the standard air box can't really be improved on (unless other mods done to the car) and the air fuel ratio (red line) was 'perfect' according to Matt, and consistent throughout the revs.
Needless to say, I can't praise Racing Line enough. He really knows his stuff and has been tuning cars for 20 years. Highly recommended. Obviously there was nothing major to change, but if I'd gone to a normal garage it'd have taken them months I am sure.
As for the drive - even better than before without that lag and I'm getting around 20% more HP through all the revs (i.e. was 55 and is now 70; was 105 and is now 127 etc.)
Just for the record Racing Lines telephone number is 01422 347744
