I've noticed some of the other exhaust manifolds (that hold the snails up closer to the engine) seem to put more torque down.....must be the extra heat or use of smaller,quicker spooling turbo's.
Than again-it could all be in the hand's of the Tuner.

The boost curve you are seeing on that dyno graph is by design. Notice the power starts at zero... I begin recording before I step on the throttle, and when I do step in, I ease down the same way I (and the vehicle owner) would on the street. From there the boost control is programmed to gradually increase boost as rpm climbs. This is part of the strategy to keeping the fragile stock engine alive at this type of power.
At the lower boost settings in the 600s to the wheels I drove this car on the street myself and the low end torque is better than my supercharged mustang. It feels amazing and changed my mind about turbo sizing on the VHR. I would never bother with a smaller turbo than this car has on it now. The response is already just plain immediate, despite having 1000-1100whp worth of turbo on it. |
