Russell – it’s so great for us to have your world-class pictures on our walls and website!
"... get on your bad motor scooter and ride!"
Sammy with MontroseRuss, whats ur ruling on this puppy?
"... get on your bad motor scooter and ride!"
Sammy with MontroseW O W – I am sure the performance of many of these cars will be a challenge – but GOSH DARN …. it looks like there will be some Gorgeous cars in the race!
I am just planning to enter my Ferrari GT250 from 2017 and attempt a build with the Bill Thomas Aluminum Cheetah with a 3DP chassis.
"... get on your bad motor scooter and ride!"
Sammy with MontroseTA – It’s never too early to start *thinking about annual planning. Some considerations:
— Reviving Legacy series only run ~2 times previously.
— Use the OLD rules to allow people to enter a car with just a set fresh of tires and a drop of lube. UNLESS some old rule/part (tires, guide, etc.) seemed to be a major source of problems – in which case – propose the Series ‘A Deux’ with REVISED RULES that remove the problem!— For all series Consider – a basic set of Default Parts, assuming that they do Not provide any proven advantage over OEM Brand or Model parts:
… Slot.IT 21.5/23k motor; SIPT28 F30 tires (and compatible 10×15-ish wheels); SICH07 Wooden Track Deep Guide; Slot.IT drivetrain (axles, gears); 19mm Slot.IT Zero grip front tires; 3/32 Carrera-ish Oilite bushings (such as to allow Slot.IT drive-train parts in NSR, Fly, Avant Slot or other brands with snap-in bushings).We always cite cost-control as a major factor supporting “SPEC” rules; but that does Not work if the OEM parts are troublesome, -or- backup spares are not in good stock from typical vendors, et al. Most members have All of these Default Parts in their Spares.
WE NEED – Long Standing Members to add their “flavor” to the club as fresh Series Managers and Officers. The door is open to >> You.
WE NEED – YOUR IDEAS – and participation – to Thrive and Grow.
WE NEED – EVERYONE to be Skilled in managing a Series – including Posting Results and Stories 🙂

"... get on your bad motor scooter and ride!"
Sammy with MontroseI found out the RPM rating of the Intimidator is 50k, the same as the Eagle, and little more than the Hawk-7 Screamer (yet has more noticeable torque than the Hawk, but is Not as hard to ‘feather’ as the Phoenix for GTP.) The Intimidator is becoming the default closed-can motor for the LMP and NASCAR Classes.
The 60k Phoenix could remain a favorite for the GTP and GP-F where 3/4 of the track you can go Full-throttle. But – the Phoenix is temperamental in that it takes a lot of sensitivity for the motor to turn-over, and at that ‘breaking point’ -at the start/re-start, or out of a corner- it can easily wheelie the car into a de-slot.
"... get on your bad motor scooter and ride!"
Sammy with MontroseA new 1-24 motor is being promoted as the legal replacement for the JK Hawk-7 and Mid-America Eagle.
It is the TOP SECRET – TSM003 – INTIMIDATOR – a sealed short can FK size motor.
Of course the vendor cant reveal any specs (morons) but it is a) obviously faster than 50k (eagle and hawk) and apparently good enough for GP-F (entry wing), where the 60k Phoenix is allowed but can be a hard to drive motor (takes a lot of trigger to get over the torque then the nose wheelies out of the slot!)"... get on your bad motor scooter and ride!"
Sammy with MontroseMOTOR CORRECTION
HAWK-7s are long-can sealed motors from JK Products, Not Mid-America (altho I think M/A re-sells the Hawks). These are 48,000 rpm motors with moderate to high torque (No TQ rating stated by JK).
They are upgrades to the Hawk-6 (40k?) and Hawk-Retro motors (45k).The “Screamer” version is a little hotter (no specs available) [Hawk-7 Screamer – JKM7-SC (Formally JK-30307SC]
A legal upgrade in GTP and Group-F (entry level wing) classes is the Mid-America “Phoenix” which is 60k and has so much torque, you will burn up the motor in seconds if you try to break it in. It depends on full speed operation to cool itself (and they still get Very Hot!)
A easier to handle motor is the Mid-America “Eagle” rated at 50k and more TQ than the Hawk but less than the Phoenix.

You are allowed to remove the studs and trim the back of the light buckets and add a washer to the front post if needed.

Sammy with MontroseNSR TIRE TRUING NOTES
COMPATIBLE NSR TIRE TRUERS"... get on your bad motor scooter and ride!"
Sammy with MontroseRuss – I have previously trued NSRs on my P&N (such as for the NSR rally series) and don’t recall specific problems. But truing the NSRs on the P&N may have made your hubs microscopically oblong, or maybe the tires are just wonky (shifted during the truing process).
For this series – I trued my stock NSR Super-grips (brand new C7R Vette) on the HUDY.
I added Thunderslot ‘foam donuts’ to fill the gap and lightly ShoeGoo’ed the tires.
My Supergrips seem to be shedding/marbling and hence chatter a little in straight line. They also require a good rounding to prevent chatter in the corners.
The Moslers and 917s seemed easier to tune. Today – I can hit 4.1s immediately with my 917. When the tires and motor warm up (50 laps?) it runs consistently in the mid 3.9s without trying.
Both 917 and Mosler have a lower CG and dont have the big caboose as compared to the Vette."... get on your bad motor scooter and ride!"
Sammy with MontroseRUSS – yes I too spent several hours this Sat & Sun trying to either a) break 4.1 or b) have a car that did not jack-rabbit in the straights or fishtail in the corners. The Supergrips marbled a little and contributed to both the jumps and slides.
After too many 4.4s, I switched back from the 22k motor to the 25k OEM motor; and went back and forth from the 32z (OEM) to 31z spurs. With the 32z I could barely break high 4.3s; with the 31z I clocked a few mid and high 4.2s but mainly stayed in the 4.3s My pinion is a 11z (OEM spec).
I also experienced more rubbing on the front tires (I need to double-check to see if I am running the 17mm or 19mm NSR-No-Grips)
"... get on your bad motor scooter and ride!"
Sammy with MontroseTA – of course we will race it : )
We will put it into rotation and select one or even perhaps 3 people (proxy style) to drive it.
…
I will be closely checking your Reifen to ensure they are legal – no experimental BFG compounds are allowed … no gluing NSR over the original sidewall names etc."... get on your bad motor scooter and ride!"
Sammy with MontroseHey – I hate to drop this on you guys but here’s some calcs that defy the recent idea of using the 22k/21.5k motors (at 11v). Since we are using S/W gears our options are limited.
Also – I did the numbers using 12v and 11v and not surprisingly, 11v favors the 25k motor and 12v favors the 22k/21,5 motor.11 VOLTS
25,000 motor rated, * 11/12v = 22,800 effective

8146 2.67 32/12
7967 2.73 30/11

IDEAS?
"... get on your bad motor scooter and ride!"
Sammy with MontroseTUNING NOTES
MOTOR – At the series voltage of 11v, some people testing Vettes are experiencing the 25k motor to be “too-hot” (jackrabbit hops and fishtails); even with Low gearing (e.g. the OEM 32/11 = 2.91 ratio, or 33/11 = 3.0).
Conversely, the 22k or 21.5k motors may need Higher gearing (2.82, 2.73) to go below 4.3s.BALANCE – the nose on the Vettes are light, so some weight behind the guide (~3 to 4gm) or on the nose of the motor-pod (~ 5-7gm) may be something to experiment with.

Sammy with MontroseSM COMMENTS:
ERIK (and others)
1 Re BMW-#1 Z4, if you are planning on the White Presentation livery- that should be NP.
2 If you can attend, great – yes show up masked and enter the fray.
3 If you cant (b/c of the kart race) – you can either drop that Round (the normal process) or leave your car and ask someone to be your Driver for round-1.
4 In general, anyone wanting to field a car but not able to attend (regardless if due to Covid, health, travel issues); they can hire another member as their driver.(I am considering hiring John to build my car and Steven to drive – based on recent GP-C history LOL. I will deal with sponsors, organizing the VIP Tent and post race parties etc.)
Seriously – if you want to enter a car but cannot attend in person, reach out to another member … let’s keep this simple and ‘easy’
