    R&D 1:1 Supercharger wheel

    has anyone tried this ?

    would like to know the benefits and the pitfalls of this or even the 1.05 pulley.

    I am looking for more low to mid grunt without going to a MOTEC for now.

    any help and advise is appreciated.

    Pro: growth of acceleration but not soo mich to top speed max 72-73 and a good exhaust sound.

    Against: increase risk of not alignement of pulleys and causing slippage and damage to belt , increase temperatire of belt causing broking it, increase rpm inside sc and you can brake inside the sc and need to change, more rpm also and increase temp inside engine causing damages, increasing rpm you need to check bearings of pulley and every 20-30 h change.

    Trip: use r&d alignement tool , buy an istrument to check afr, buy a big fuel pump, pressure regulator and r&d fuel management minimum, use a bigger air system.

    Conclusion: between pulleys the less agressive and safe is 1:1. With other the risk is very big. You need to have good mechanical skill to solve that problems as before written otherwise you will drive a loy towards your mechanic. If you buy parts you need to tune fuel with some instrument afr.
    Now rouge has good product as its medium pulley as 1:1 and he says that bearings last 100 h and due to holes the temp of belt is more less but no one real sperimental test. He also have heat barrier to decrease temp of air going inside the engine.

    Otherwise if you don't want to learn about tuning fuel and buy other afr stuff there is jetworx marine australia. Todd has created a pulley kit with inj, fuel pump, new timing wheel and only one pulley. He has made test and it is a co
    pelte package o ly plugand play. No tuning or other. He is a very kind and learn person.

    It is a long summary. For any info here i am. I am not a seller but a guy who broken balls to all kind forum member here and i have learn it and try to share.

    A question: is it good have too many risk and probs for only 3 mph??
