    Torque Plate mod, anyone?

    Anybody tried the exhaust manifold spacer from Rad4?
    How does it perform?

    I have it installed, They claim its good for about 50 rpm. I had a batch of mods going in at the same time i installed the torque plate, I cant tell you how many rpms i gain from the plate per say but i did get a substantial gain with the plate and ross nemos T/B mod.

    Found it in the online store, maker is a member here

    BLUE, I already had my TB bored from 58 to 60, so you reckon the plate would be worth what it costs?

    Let me put it this way..... If your looking for a gain in rpms that will put you closer to the sweet spot which for me was 8100-8160 then yes do it. If you are already in the sweet spot then I would hold off IMO. You'll either have to tweek the prop or install a adjustable nozzle that alow you to swap rings in order to stay in the proper rpm range without banging on the rev limiter. Unless of course you are running an aftermarket ecu that has a higher rpm limit then throw anything at it that will give those extra rpms. What are your max rpms now consistently? What's you current setup as far as mods?

    We make them and Jerry sells them, A stock 215 will get 80 - 100 rpm gain and 1 mph. Lowered EGT at the piston face and subsequent longer engine life are another bonus as well as enabling the SC to be removed without removing the J pipe on earlier applications.
    I have not tested on the IS platform as yet but we are working on that.
    There are previous threads on the torque plate and some members have had as much as 200 rpm with thier combinations when adding the plate.
    Hope this helps.

    How come top dogs Riva, RR, SD Centre, etc, havent developped their own yet?
    if it is such a valuable mod for the average rec rider shouldnt it be a more common part? seems like not so many forum members have tried it yet

    BLUE, understood & agreed
    My max RPM is 8160 right now (07 RXP, stock ECU, stock injs, X-charger, RRFPR, XS-IC, 4" front air, 15/20), but there s no regular pattern, as I m located in a tropical climate with quite unstable weather
    I ll be all over rev one day, then down to 8000 next day, that s in the cooler dryer season
    During the monsoon, with temps in the high 90s and humidity at 80%, I wont get more than 7400-7800
