The same cosworth they were using in the first place with a sticky label that sayes jaguar?
unlikely...why would you use a bespoke, expensive, fragile obsolete F1 engine over an off-the-shelf OEM production engine?
Out of interest, with an OEM engine and it's more sedate operating RPM's, do you still need a gearbox? (what shaft speed does the pump need?)

Now what engine are you using to drive the fuel pump?
Have a guess! Shouldn't be difficult to work out........I would imagine it would be a lot easier to just get a slightly bigger diameter impeller for the HTHP pump than mess around with gear boxes etc!

Although, slightly ironically, the Cosworth F1 engine they were going to use has it's roots in the V10 engine designed by Cosworth for the Stewart, then Jaguar F1 team....... Funny old world ain't it ;-)

I am just finishing the car pump design, having re-designed the test pump. Our original pump from a previous supplier was around 25% efficient, the new one is around 60-65% efficient, supplies enough flow & pressure at 10500 rpm for our year two rocket, so for year one we simply turn the engine revs down.I would imagine it would be a lot easier to just get a slightly bigger diameter impeller for the HTHP pump than mess around with gear boxes etc!
