2020 Masters Of Motors Competition - Studebaker Power Team

Post by Jeff Rice » 21 Feb 2020, 14:03

Masters of Motors competition....
Has a nice ring to the name.

The JE Piston and Amsoil companies have joined together to continue on with the old Engine Masters Challenge.
Hot Rod Magazine has opted out of sponsoring the event and since they owned that name, the new event organizers have chosen to rename it the Masters of Motors competition.

Same location, same date, same classes, and basically the same rules.

More to follow.

(2/21/2020) "Digger Dave" Molnar has committed to competing again this year.
A new engine combination is being prepared. (Jack Vines, you will smile :wink: ).

(2/21/2020)
The Studebaker Power Team is pleased to announce that Ken Evans has stepped up to the plate and donated a set of steel 4 bolt main caps to make our bottom end as strong as possible.
Ken has also kicked in a bare Studebaker V8 block...

THANK YOU, KEN!! :D

Can't wait to see what Digger is coming up with this year.

Probably not with the engine package we are building for this year.
Last year's engine was right there (396hp on the Indiana dyno, 389 at the event). If we had run the aluminum rocker arms, tweaked the carb a bit more and changed the rpm range, we would have hit 400hp with the 309 cid setup real easy...and there was more to be had with a little more development.

But this year (2020) will be different. There is a total point scoring advantage to run a smaller displacement engine. They set a minimum displacement of 250cid and anything under that gets a 10% penalty. To muddy it a bit more, in 2019 (and 2020) you are allowed a max overbore of .065" of a factory built displacement. So you can only bore .060" over a 259, a 289, or a 304 with a Stude V8. Our 2018 setup was a stroker crank with a .125" overbore. They outlawed stroker cranks for 2019 so that was out and our block was way over the allowable overbore for a 259 or 289, but not for a 304. So for 2019 we set it up as a 304. Carefully reading the rulebook on scoring shows us that there is a point advantage if we can take a 259 out to .060", and raise our RPM range. From what we learned in 2019, the 259 +.060" engine can still perform well with a few changes and actually score more points (than with the 304+ .060" combo).

More specifics later.

One area of improvement is the headers. The rules for 2020 have been relaxed and we can use custom built headers (instead of store bought headers that Hot Rod Magazine insisted on in 2019). We skirted that rule anyways, but we learned that the collector length the set of headers we ran in 2018 and 2019 (that the engine liked) could not be set to the maximum length because of the length behind the engine. They were too long for the dyno room (and the rule set for that constraint). But, if we build a new set of headers that sweep forward before heading back, we could get to the optimum tube lengths without running too far back behind the engine. There is no rule about how far forward your headers can go. Just a rear termination distance rule (to allow them to hook the headers up to their exhaust extraction system in the dyno room). Stepped headers are not allowed (something our current headers have).

Another area is the choice of intake manifold.
For 2019 we ran an Edelbrock Performer dual plane intake. On the Edelbrock dual plane intake, and our dyno testing has told us a single plane intake with slightly more plenum volume would add some HP at the upper RPM range. The Edelbrock Torker 2 single plane intake does that. So an Edelbrock Torker II is being built to test that theory out. We also plan a dyno room RPM pull range change. The max allowable that you can select is 7200 rpm. In 2019 we ran a 3700 to 6700 RPM range, as the avg torque curve and avg HP curve was best there.
For 2020, our analysis says, with the changes planned, we will be better off using the 4200 to 7200 RPM range. Actual dyno testing will finalize that choice.

Great to see Digger at it again. I emailed him and let him know I will volunteer to fabricate whatever I can. Are modified oil pans still a no-no?

We'll all learn things as Digger builds. That 259" combo is similar to one we built recently. The Scat/Eagle 7" flathead Ford rods are a cost-effective way to go with a 259". Getting enough compression becomes more difficult with the smaller displacement.
our dyno testing has told us a single plane intake with slightly more plenum volume would add some HP at the upper RPM range.
Agree, we're milling out the dividers on a late 2-bbl intake and adding a spacer to make it a single plane plenum as far in as we can reach. We were limited to using an OEM iron intake and exhausts, so those most likely are restricting power production above 5500 RPM.
So an Edelbrock Torker II is being built to test that theory out.
Has Digger considered a tunnel ram?

Yes. Torker II seems the best choice.
No. No tunnel ram. (Rules) We aren't pushing that issue as we are happy with the exemption we were given.


(Rules copy)
314 – INTAKE MANIFOLD

Engine must use a mass produced commercially available cast aluminum or OEM single four-barrel intake manifold with centrally located carburetor / throttle body flange required. Intake manifold INCLUDING all additional gaskets and spacers may not be taller than 8 inches measured at the carb / throttle body mounting flange. The measurement of carb flange is the average between the front and rear dimensions taken from the engine china rail to a straight edge across the carb / throttle body mounting surface. Pontiac engines will be measured using a line drawn at deck between both sides, front and rear. Vintage entries (Pre ’58) are exempt from intake rules.

I was asked about the custom pistons necessary to mate with the 7.0" rods with .750" pins in a 259". These were ordered from RaceTec/AutoTec with a 1.424" compression height to give a .004" deck height on our block which we had squared in the BHJ fixture. The engine only has dyno time on it thus far, but they work well.

(2/25/2020 - Masters of Motors Update)
Rick Delaney and Dan Wioch, fellow Studebaker Power team members, picked up the engine block and 4 bolt main caps yesterday.
Making arrangements to get them over to Digger Dave in Mishawaka, Indiana.

(2/25/2020) Studebaker Power Team - Masters of Motors Update)
Masters of Motors Sponsor Updates!
Steve Grant and Tom Donothan have stepped up to the plate to provide the team with an air bleed jet set and a fuel jet set.
This will greatly help the ultimate tune in the dyno.

THANK YOU STEVE AND TOM!
