Having made 215 bhp a good few months ago at The Racing Line, Matt went off to hatch a cunning plan; more power! After various intercooler / turbo and clutch failures, the plan finally reached fruition this morning at the Headquarters of Dyno Demon, where Matt was having his Apexi AVCR set up. The results? 314 BHP at 1.2 Bar with 300 lb/ft torque. The operator reckoned there was at least an extra 15 bhp in there (it did 322 bhp at 1.3 bar easily), but erred on the side of caution. So congratulations matey, it's been a long and sometimes painful journey but the end result surely justifies it.

What boost was that running midrange? 1.2 Bar straight through. Sorry, just re-read that. Not sure but think it'll only be a matter of time before Matt posts up the graphs.

Right, I'll post up the graphs when I get home tomorrow, I'm on a laptop at the moment. spec: GT28R, Blue flame full system 2.75" with V-band adapter, decat, SIP, K&N, Pro Alloy FMIC, Gtec 2, walbro+mod, Apexi AVCR High setting: 314bhp at 5900rpm (I think it was 266 at the wheels, didnt get that on graph) 300lb/ft at 5000rpm boost 1.2 bar midrange, 5000-6500 drops to 0.9 bar. Low Setting: 292bhp at 6500rpm (246 at wheels) 270lb/ft at 5000rpm boost 0.85 - 0.9 bar all the way Fuelling was 11 afr at 4000 rpm then gradually up to 11.7 before dropping just under 11 again right at the top. He did one run at the start at 1.3 bar and it made 322bhp before any tweaking had been done! I decided to run 1.2 bar for extra safety and efficiency. Everyone there seemed really impressed with how the car performed. They had to keep getting out and strapping it down tighter because it was trying to escape! There was easily more in it but I didnt want to push it any closer to the limits of the standard internals Cheers Craig

Nice one - IMO completely the right approach to have. Nice safe level of power and nice and driveable.

Maybe, but it's staying like this for now. No more money will be spent on it for a while unless it needs it.

Bravo Matt.
Torque seems a tad high for that boost level, but im sure it pulls like a train.
When is the turbo kicking in?

It's been behaving differently on the road than it did on the RR - but I've sorted it now.
On the RR full boost peaked at 1.2 at 3700 rpm, but it spools up faster on the road - about 3200?
The settings that he made which gave 1.2 on the rollers was giving me 1.4 bar on the road, so I've been experimenting on the way back from the midlands meet, the closer it is to 1.2 the faster it is. way faster at 1.2 than 1.4 - he said that would be the case, leave it at 1.2 or it will go COMPLETELY wrong. That's how complicated the AVCR is to set up well.
Graphs on the way...

1. High setting - Flywheel Power and Torque GRAPH 2. Low setting - Flywheel Power and Torque GRAPH 3. Both settings - Boost and Fuelling (top right shows power at the wheels on low setting - high was 266) GRAPH

Both settings - Boost and Fuelling (top right shows power at the wheels on low setting - high was 266) GRAPH Matt, Just looked at your graphs and hate to tell you that they've been ran in the wrong mode. Your car has been ran in Shoot 4F instead of Shoot 5F. The set parameters for each are different. 4F is a dyno mode with paramteters for 4 Cylinder Forced induction cars, 5F being the 5 cylinder forced alternative. This will distort the figures and curves you have. Jules.

I cant see how it could make much of a difference... the principle is the same, regardless of how many cylinders the engine has.
If they do run them all in 4f like cowboy says then the result from the RR day there a couple of weeks ago show that it's accurate....

I'm sure they'd talk you through what the setting means and what difference it could possibly make if you ask them. Maybe there isn't a 5, just 4, 6 and 8?

After doing some searching for "dyno dynamics" it appears they dont have a 5 cylinder mode, been mentioned on here before. does 314 at the flywheel sound about right when it's 266 at the wheels? sounds about right to me.
