The RP968 It's a bit of a thing...

Great job despite not quite getting to the top step Rod. Time was the enemy (no pun intended) and you just had too much on your plate to get all zipped up for 2017. A real shame to show only glimpses of the future so to speak. An unbelievably incredible team effort just to get you into 2nd place. And I'm sure it was a minefield being project manager with new body, suspension, ECU, and of course the Billet motor. Coulda, woulda, shoulda..!!!

Rod, noting some future changes you mentioned, are drag reduction moveable wings legal or do the rules state that wings and elements be fixed.
Secondly, the active suspension, is this your solution to lower the rear on the straights to lessen the rear wing angle for drag if in fact "wings must be fixed"...?

They are active dampers, so they can only control the the springs movement, not actually move the car. Lots of benefits with them.

When we decided to take Thor out and put the 'little' engine back in we did the big end and crank bearings. Yes they were a bit tired, that was the second set of big end (Michael Mount style) and first set of crank bearings in two years, not a lot of miles, but really it's normal to do that in a race engine, I think that is acceptable wear for that power level. We have done a few head gaskets of course, but engine is fine now.

holy ****ing **** that billet motor is ****
is it a taller deck height than stock? my memory may be fuzzy but the motor-mount boss to crank centerline distance looks larger than stock.
rod, did you give any consideration to hydraulic roller cams since you were going all-custom-everything?

The engine should make plenty of power.

I meant an active system re. Formula 1, like the '93 Williams.
Some teams had simpler systems but not as sophisticated so other than Williams' fully developed car, no other team (that I know of) invested further since it was under ban consideration. At least the Benetton could over ride the ecu with a push button to lower the just rear of the car, thus lessening the angle of attack on the rear wing for less straight line drag.
You need me to come over there....?

BTW, you running an electric or belt drive vacuum pump on the crankcase or is there no benefit with dry sump..?
Where do your crankcase gases go...?

We run the crankcase in vacuum. There is a breather off the tank.
A full active suspension system is way beyond our capabilities. Just springs and bumpstops, quite simple. We can control heave and roll in the software, and the driver can change settings on the track.
Yes those pistons are very shallow, but big diameter,116mm. The aluminium rods are substantial but quite light.

It was great seeing you and the car on site. You got a truly amazing piece of car and engineering there Rod! And very impressive work getting the car ready between Friday and Saturday.
Achieving the results you did with the current power level is fantastic and I suspect we will see the first sub 1.20 lap next year with Thor up and running

Thanks Gustaf, great meeting you. We’ve always had minor problems which have limited our testing, but we all know the potential. Don’t know if just a 1.19 will be good enough next year. I think we will need more than an extra 300hp...

Maybe Elmer can build you a 928 based billet block using Thor heads ;-) Turbocharged billet 8L should give you all the power you could ever need!
