    Holman Moody Intake set-up at SEMA 2023

    At SEMA visiting the Superformance folks from Hillbank and Downforce Motorsports saw this intake set-up on a fresh Mark II build. The attachments to the side intakes are in the cockpit. From the 1967 Holman Moody car crashed at Le Mans with the J car driven by Mario Andretti.

    Lowering the seat pan in an SPF?

    My seat has been shaved down about as far as possible. Only a helmet clearance issue for me as I have room day to day driving. The front edge of the seat when shaved down can help knee clearance by flattening out your hip/leg angle a bit. If possible keep the seat back as thick as possible as...

    Fueling an SPF Mark I

    I open both caps and fill from one side and have no issues. Only consideration is that the opposite side cap when open if on a decline can spill over before the side being filled tops out. I listen for the gurgling of fuel on the opposite side as the warning to slow down flow rate.

    Wheels and tires on SPF

    Avons great on street and track for my purposes. The ride difference is big when going to a bigger rim and not in a good way.

    Any 6"2" tall owners?

    6'3" 240# SPF with Gurney bubble and pedal box all the way back. A lot of foam removed from seat. Fit is fine on street, head clearance minimal with helmet on but doable. Having custom caron fiber racing seat fabricated and will drop the floor to accommodate.

    SPF Front Hub Retention Ring Failure

    The Olthaff Racing upgrade as well as the other side retention ring which also failed. In my opinion these should be inspected on all SPF front hub assemblies. The Olthaff upgrade is a higher quality material and refined. I recommend highly. Olthaff guys have been more than helpful.

    SPF Front Hub Retention Ring Failure

    Some have had custom made and I hear they work well. For now we are looking at redesigning the ring and more frequent bearing seat checks.
