hi im hoping for some advice, had my sup for 4-5 months, for past month its been making a loud thumping noise from under the car (gearbox/engine area) when at full throttle accelerating from 4750rpm upwards. mostly in 2 gear onwards.

 

just wandering if anyone else has experienced this in a N/A manual SZ/R, or turbo manual.

 

its sounds like prop or g-box but no play in any of them which are visible.

 

really frustrating as im thinking it could be engine problems too, would just like to know if anyone has seen or herd of this type of problem.

thanks

sam
