Good eve to all on Passion Ford,

Last week i dyno tested my alloy blocked old spec headed 2litre turbo yb and got some interesting results?

This has been my own project for over 6 years now and has taken all my knowledge and skills to make this happen.

This engine has been my own personal goal and i have found it very interesting to see how to push the old yb into the unknown?

I built a very smilar specked motor that went to Cyprus many years ago that dynoed at 1097bhp this created many mixed reactions and lots of reserved judgments.

So i have built this engine and dynoed tested it here in the uk, and yes it can be done!!

I must say with out the new alloy block this would of not been posiable!! as people who have pushed ther own ybs to big power know the cast blocks will break what ever you do to them i know as i have found out.

The power from this engine comes from head and cam control the rest is a battle to make it all stay alive.

Every part of this engine has been custom made and designed.

1) Dry sump 5 stage drag race pro stock( custom 3 stage pan)lots of internal scraper and windage.
2) Crank ??stroke but special material and heat treat ment and coatings
3) Rods Custom spec very special bolts and coatings
4) Pistion ?? bore again coatings and special ring pack and pins
5) Harmonic damper custom made and very important !!

6) Now this is where lots and lots of hours on the flow bench different port sizes, valve sizes head and stem and material, valve seats, material angles

7) Cams again custom made to our specs and special coatings

8) Valve spring very important area, make and material, nothing from the uk here!! we learnt this many years ago with my n/a motors that pulled 9500rpm

9) Inlet mis copy but we worked very hard to flow it over 800bhp

10) very trick throttle body (bmw f1 off the 1500cc turbo motor)

10) injectors 1750cc per cylinder

11) turbo gt42 rs

12) motec engine ecu Coil on plug

So thats a breif spec, every thing else stays with me.

We ran the motor to 8500 and 9000rpm on vp import fuel and then an vp c 85

full boost 2.8 bar

I know this will case all sorts of reaction but to re cap

1) Its a development engine used to see what makes the yb tick
2) I wanted to see how much it would take to do this power out put
3) I wanted to be the first guy in the uk to do this
4) Yes it would be only for drag racing but with a turbo swop eg gtx 35 it will run 700bhp
and pull from 4000 to 9000rpm and make a very strong race engine or gtx 30 and run 500bhp awesome street motor,
5) So the engine i self will take over 1000bhp with the correct turbo, or less with a different turbo.

I will post dyno sheets and pics very soon!
