(B) Duel Throttle Body System - (1) Parallel Systems (Still in design phase)

RPW is researching two new styles of twin throttle body systems for these vehicles. The first design will run a parallel side by side unit with a modified intake manifold. This will enable the single pipe air flow meter system to be reused and tunign via a piggy back computer system.

Standard Upgrade replaces the stock single 65mm unit with two 52mm units - as described above. (Street / Strup duties modified)
Stage 1 Performance Upgrade is the above unit upgraded to two 58mm units. (Street / Strip duties modified)

Are these available yet and does anyone have one installed that can comment on any gains attributed to it's installation?

Am i correct in my understanding that this system also allows you to retain use of the stock Magna MAS/MAF sensor and as such there is no immediate requirement for a piggy-back ECU?

Cost?

i think std upgrade dose not require comp mods

stage 1 i think dose

No they are not available yet as when we ordered the first models from the USA they sent them via sea freight instead of air freight.

So they won't be here until middle of April.

They will require a piggy back ECU to compensate on fuel and ignition but will still utilise the MAF sensor and a single air intake pipe.

No pricing available at this time yet.
