    Turbo boosting differences

    Im getting a difference in boost on my turbo RXP.

    With the seat on i get 15.2 PSI and with the seat off i get 16.5 PSI.

    I think its just breathing in hot air from the turbo.

    I have the filter just coming straight off the turbo.


    Has anybody had any experience with this?

    Keep the seat off and work on your leg muscles Turbo generates a lot of heat. Winter riding is the best as it keeps your bottom end warm.................Jammer 1

    Hi Rik, yep, looks like you have answered the problem. This is another reason i won't go for turbo conversion. The heat dissipated in the bay is too much.

    The GT-R had problems very similar. I tried all sorts of ducting with 12v cooling fans to combat under-hood temperature soak. Sometimes it was a nightmare in summer if I monitored the temps there. I have lost sleep over detonation.

    Heat is also exaggerated with turbos, as the exhaust turbine becomes more of a restriction as the gas flow increases too. The draw back in turbos.

    12v fans pulling air out from engine bay is a good way forward, the type you can get for PC's are good, with heaps of ventilation.

    There are a couple of solutions in development right now to combat this problem...

    I gain about 1 - 1.5 mph when I pull off my seat. At least for now.

    I guess you can spot the Turbo riders by their reddened cheeks, or holes burnt in their suits/shorts...
