Focus ST MK2 Tuning
Discussion
A mate and I were having some Facebook banter about cars, he challenged me with his tuned White MK2 Focus ST Estate (Ecto 2). He claimed 300 plus bhp and 430 plus lb/ft of torque, the 300 bhp seems pretty believable for a 250 BHP car with the usual Remap, exhaust, and filter but 443 lb/ft of torque ?
I thought he had made a typo and it was 330 lb/ft, but he posted a dyno chart 443.7 LB/FT at 2109 RPM and 328.8 bhp.
Anyone else heard of gains like that, that is an immense amount of torque for a 2 litre turbo isnt it ?

You can't get a MK2 estate, you can get a Mk3 estate however, that came with a 2.0 4cyl 250bhp engine. the MK2's use 5 cyl 2.5l modified Volvo engines with 225bhp as standard. Both engines can see 300bhp with a downpipe, CAIS, bigger intercooler and a remap.
The mk2 does have a lot of torque, but i won't pretend to understand how torque works
edit - just seen the dyno, it's a Mk3

He said that the Mountune maps are designed with the warranty in mind but I cant really get my head round that there is another 100 odd lb/ft left untapped, he mentioned the Mountune MR300 map which doesnt retain the warranty but I dont think that is 400 plus lb/ft, 300 odd.
Still he provided a dyno plot, but to me that sounds more like NM than LB/FT, isnt there a correlation formula for torque vs bhp ?

Yeah, 430 lb/ft by 2000 rpm in a small FWD car, I would imagine its pretty flexible.

I thought torque and bhp always crossed over at 5252?
(I could be totally wrong though!)
Theyll be artificially dropping torque off to prevent the something going pop I should imagine - I have a similar shaped curve on my megane (further up the range mind) to prevent it going too far over 300bhp and bending rods etc. (I could be totally wrong though!)

I haven't seen a lot of them so feel free to correct me PH but I've never seen a BHP line go up so quickly and then drop to so little.
Maybe it's these new fandangled engines.
Its not its an evolution of the engine i have in mine . It does have much fatter rods though , i am dubious of those figures id want to know about AFRs ,boost & wgdc . Maybe it's these new fandangled engines.
