    Fitment was perfect

  10. Rob Roberts (store manager)

    We went with the elbow first because we could tell the design was far better than OEM and wanted to see what the supposed added flow/reduced back PSI would actually provide. With OEM impeller we saw -6*F cooler at the track!

  11. Richard M. (verified owner)

    Probably will never know if it works better than the stock elbow, but it looks cool and fit like its supposed to.

  12. Maik (verified owner)

  13. Bruce Bonnefis (verified owner)

  14. renaud scott (verified owner)

    nice product, price is fair, was too expensive before.

  15. Kart Racer (store manager)

    I installed the impeller and GEN II high flow elbow on my outlaw kart. Jason said most kart racers are seeing 10*f cooler with the impeller alone and not sure what additional cooling the high flow elbow will provide. At the track I saw 20*f cooler running! Reducing the back pressure on the impeller really helped! We will now start leaning the jetting to pick up even more power.
