Really strong pistons/rods/crank/bearings, I take it?
Simon, what sort of ballpark figures to expect the 321H to make on a v.1 ODB with v.1 WRX hydraulic heads (with all appropriate supporting mods, of course), on V-Power only?

It is unfair to compare VVT cars to none vvt cars imho. I could stick up a graph of a 2.5 car with the vvt heads on a t+, that would out spool anything here.

Harvey, the SRR rollers (as I'm sure other rollers do too) seem to make the cars spool later. My car on the road did manage 1 bar at 2600 rpm, yet same spec got to 1 bar at 3100 on SRR

Would that be the slight lag induced because of having to overcome the rollers' initial inertia?...
Or are the rollers really light and instantly free-spinning, therefore not accountable for that 500rpm later spool-up point?

MD321H and the vf28, on my p1
vf28 was after decat, big kn and a remap.
Same spool as the vf then leaves it for dead.
The delta dash was done on the same bit of road, same gear and very close air temps.
love the 321h it did every thing mark and Bob said it would.

That's impressive! Basically a 400bhp turbo producing the same drive-ability as a 320bhp turbo with all other things equated as far as possible.

what other mods do you have in place?? intercooler and injection and such??
321h would of done 400 lbs/ft. with more boost on a built engine.
But mine was a standard p1 engine so was mapped to 1.5 bar tailing off.
Agree - I'm currently making 377lb/ft at just over 5K rpm on a standard 03 STI engine using a 321H running just over 1.7 bar tailing to 1.5bar top end. With a built engine and 2bar of boost, I expect to get well over 400lb/ft
Forgot i'd even started this thread!! After what I learnt on here I ended up going for a 321T. Should have the car back with it and a **** load of other bits done in the next week or so
