    Rest assured they are just on the limit, i.e. 1230 kg and probably 350 BHP plus 700 Nm of torque. The early/mid 90's GpA cars probably had up to 450 BHP, so if on boost, extremely powerful.

    Yes I think I remember reading years ago they had "around 300" bhp but 500lb/ft of torque but that they pretty much had all off that power and torque at any given revs and of course the anti lag to get them off the line.

    Early grpA cars had the benefit of a 38mm air restrictor (later changed to 34mm) and so probably had nearer 400bhp with north of 2BAR boost.......

    I take it these engines were built to be able to run up to 600-700bhp and similar torque if they wanted ie like rallycross? But just due to the rules restrictions were in place. What a great job it would have been to be an engineer in the likes of prodrive in the 90’s

    Think durability definitely plays a role here. Rallycross is five minutes sprint races, whereas even in the late 90's you still had long transport legs and stages of almost 50 km (roughly 25 minutes driving time).

    Prodrive had a scheduled rebuild every 1000kms from memory

    Dont want be to smart but legacy was down on power in comparison with other gr. A cars beacouse of water-air intercooler, the bigest power had imprezas at 94 around 350ho. But they were down on power beacouse of small turbo iin comparison to escorts. With 34mm restrictor and small ihi turbo in 95 cars were mor drivable than escorts with big turbo.
