Harvey Smith would have told you no...and had you taken your car to him, he'd have proved it.

Mine, for example runs a 2.5 with a HS TD05 20G, and spools strongly, hitting 1 bar at under 3000rpm.

In therory yes, going with a big front mount will increase lag.

However, in reality the increase will be so incredibly small you will never ever notice it. A good mapper can make all the difference.

Changed from a hybrid core to a hyperflow, if anything it spools quicker and the core is nearly double the size

Internal air flow is more important than size, a crap fmi will have crap internal structure and the air will bounce around all over. decent core will have a good internal airflow, cool better and spool better


This is why cheap ebay jobies tend to not do the job.

Hi there

We are run Japspeed FMIC at 490bhp without the one problem.

I don't think you will have more lag with DR725 core,but still think Japspeed FMIC will be enough for yours needs
