Some of may have seen my post in the pictures bit about me fiting a 3L hybrid lump into my ST24 Mondeo (if not, well I've umm, just fitted a 3L hybrid lump into my ST24 Mondeo, LOL)

Anyway, it's all done now & is up & running so I took it to get the Unichip remapped today. I was a bit shocked to see it only made 206bhp & about 196lb/ft torque.

Here's the spec of the engine:
ST220 3L Block
ST200 Heads, ported/polished with 3L Vv's fitted
ST200 Cams
ST200 Flywheel (lightened to 16lb)
ST200 19lb Green Injectors
ST200 Modified Wiring Loom
ST200 Upper Inlet Manifold
ST200 Lower Inlet Manifold
ST200 Throttle Body (Optimized)
ST200 Mongoose twin exit exhaust
MSDS Ceramic Coated Tubular Headers
Custom stainless steel Y-Pipe & de-cat
Techniclutch Stage 1 'Fast Road' Clutch Kit
Blitz induction kit with 5 large cold air feeds
75mm Pro-Flow MAFF
CTA intake pipe
Unichip
EGR Valve removed & UIM blanked
Throttle Hang Mod
Magnecor plug leads with Denso iridium plugs
Underdrive power steering pulley
Dual Mass Damper
Polyurethane bushed front & rear engine roll resistors

The guy I got the basic engine/heads off had a dyno print showing 290bhp but it did have Buckshott Motorsport UIM/LIM (with no secondaies)/TB but was set up on a standard ECU & was running 17lb injectors & a massive K&N air filter

So I guess what I need to know guys is does this sound right to you?
Is it likely I am loosing 80bhp & around 40lb/ft torque by putting on ST200 inlets?
 
Sorry, but unless you have some FI or a full out race engine with insane compression and race gas you won't get 290whp. Also the 17lb injectors would not come close to supporting 290whp. 19lb injectors wouldn't even support 290whp.

Your numbers really aren't that bad. While they may be slightly low they aren't horrible. Search around for other dyno sheets on the board and you'll notice you are only slightly below others.
 
Are those truely bhp numbers? If so, the whp numbers are a bit lower. My WHP on my old 3L Hybrid SVT were identical to your BHP numbers. 206whp and 196wtq. :cool:

I'm told that the figures I've quoted are at the flywheel guys so I'm assuming that this puts a different spin on things?

Would I see any benefit from an optimized Mustang 75mm TB over an optimized SVT one?

Also, do you think it would be any benefit to get the Buckshot LIM without the secondaries?

Cheers guys

And just how did they get a flywheel number from an engine already installed in the car?

Most likely that is wheel horsepower. Flywheel horsepower is approximately 15% higher.

You know in Europe they use BHP as measurement right?

If you would like to convert from whp to bhp heres a way to get an approx ammount. For a fwd car its about a 15% loss.

179whp x 1.15= 206bhp approx.

From bhp>whp just divide by the %.

206bhp/1.15= 179whp.

They certainly are opening up as you can feel it starting to break traction when they open.

I went for the hybrid route as it was an engine that had been built by Autocraft SVE (a company who deals in Duratec's over here). A mate had it in his car for a year but then decided to break his car as the rest of the thing was shot. The engine had done 6000 miles so I offered him some cash for it & the deal was done so all that was left to do was take it out & then put it in mine.

To be honest I'm at the stage where I'm not too worried about the figure as it goes like a rocket & leaves my mates ST220 Mondeo for dead, easily !!

As you guys have said 206whp sounds about right for the mods I've got so I'm a happy man really.

Cheers for the input though guys :)
