hi all.
can any one tell me what the best pair of cams is for an escort cosworth rally car running a 34mm bd10 and bd14 cams t35 turbo quaife 6 speed sequntial box plated gripper rear diff quaife atb front diff etc
engine is running motec m4 managment with anti lag and water injection etc etc with restrictor in it made 309 bhp and 387ibs torque on engine dyno.with restrictor out made over 600bhp (rallycross spec head) its just went out in my mates evo 6 and he only has 295 bhp but is 640ibs with 34mm restrictor. is this sort of torque acheivable out of a yb engine running a restrictor not botherd about bhp just want more torque.What mods would be needed to see that torque if at all acheivable ????
its just engine rebuild time is looming ever closer

The WRC Cosworth engines run 10:1 compression, and this is what you need (combined with a massive mid-range boost spike) to achieve this kind of torque. Speak to Harvey Gibbs at SCS on 01733 576 614, he builds these rally engines all the time .

Dont think you going to see 600bhp on a t35.
