Company Background

Simon Armstrong with Mika Hakkinen Ultimate Performance Limited was established in 2003 by ex Formula One engineer Simon Armstrong.

Having started his career at Weslake Developments, Simon completed a degree in Automotive Engineering & Design at Loughborough University in 1990. During the final year Simon was sponsored by Weslake to study combustion in a 14,000rpm motorcycle engine to support their commercial involvement in a 3.5L V12 sportscar engine programme. The findings of this work were presented in a published technical paper to an international conference in London .

East Haddon Hill WorkshopsFollowing three further years of race engine oriented experience at Weslake Simon was recruited by Ilmor Engineering as Mercedes began their Formula One build up with Sauber in 1994 and before they started their ongoing relationship with McLaren in 1995.

A year was spent at the Ilmor factory in Northamptonshire developing the Indycar 2.65litre Methanol V8 turbo engine, the last 3.5litre F1 engine and the first 3.0litre V10 a period during which Simon redefined the way that the cylinder heads were port-machined. Simon then went racing for two years with McLaren International providing engineering support to Mika Hakkinnen and to David Coulthard.

From 1996 to 2002 Simon took overall project management responsibility for the Mercedes F1 engine programme, a period which saw McLaren take two constructors and one drivers world championships in 1998 and 1999. This period also spanned the last years of unrestricted formula one power when the most powerful 3litre naturally aspirated engines produce 925bhp – over 300bhp per litre!
