Another fantastic Coupe back out on the roads, this Black LE belongs to Adam aka Knight7660
He has been working on this between long tours away in the army, but finally it was ready to go boosting!
Engine spec is as follows:
GT2871R 0.64
Forged pistons
Steel rods
Standard head
Standard cams
FC 3" 5-stud downpipe
3" exhaust back
Pro Alloy FMIC
6-paddle clutch
880cc fuel injectors
External swirl pot + motorsport pump
FC Big MAF conversion
FC Stage 5 remap + 3-stage boost switch
1.8bar - 1.5bar432bhp @ 6750rpm
382lbs/ft @ 5200rpm
Ah yes, the above results are from the infamous Surrey Rolling Road Dyno Dynamics aka the "heartbreaker" ! All from a little GT2871R 0.64 turbo too with some pretty nice torque.
Adam has a three stage boost switch which allows for a more sedate 1.4bar constant setting, a progressive 1.3bar building to 1.5bar, and then a full force 1.8bar dropping to 1.5bar. Part throttle boost is also controlled proportionately according to throttle position, so it offers maximum drivability and control.
Of course we did have it on my dyno too...
1.8bar - 1.7bar452bhp @ 6750rpm
367lbs/ft @ 6226rpm
So less torque as expected from my dyno, but slightly more horsepower as I pushed the turbo a little harder to hold more boost. However, on the road I tailed this of to 1.5bar as shown above on the Surrey graph in order to keep everything a little more consistent and efficient.
On the road it is extremely fast and drivable pulling hard all the way to 7000rpm. It will also see some track action, something that the boost control will really help with when coming out of corners. However, I know Adam has designs on going even more extreme in the future, but for now time to enjoy...
