Baffled Twin Turbo Pipe Modification - Power and Reduce Turbo ShuffleI received my baffled twin turbo pipe through the post today. This mod is designed to help the air flow restrictions of the standard y-pipe.
The standard pipe causes a restriction in airflow because the air coming from the front turbo merges with the air from the rear turbo at almost 90°, causing turbulence and a loss of efficiency. By placing a baffle between the two halves, the air from the front turbo can be "bent" to meet the rear turbo in the same direction.
The added benefits are that it can increase throttle response, help cut down on turbo shuffle and increase output by 10-15hp.
The modification is quite simple; it just requires an aluminium plate to be welded inside the pipe, or you can buy a pre-modded version from the GTR Owners Club shop.
If it is dry, I will have a go at fitting my pipe at the weekend.
I have noticed increased throttle response since fitting the baffled twin turbo pipe. However, the shuffle is still present (I quite like the shuffle sound anyway). I can't say I notice any power increase, so I will let the dyno decide if there is any.
