LMP-E/GT-E endurance event proposal

[Luke]

Hello Steve,

It looks like I don't need to let you know because ...

Gordon explained it all - suggestion and interpretation - in a thorough way.

Although - there's one thing I keep thinking about and believe its a great balance racing field of regular drivers and cars alike with these points ...


• Six notable slotcar "builder" persons. Note: TSCC (names in red) Club drivers.
• Everyone who is interested can prepare as many cars for each of the two (LMP-E/GT-E) classes as they want or are able to.

• 1. Gordon
  2. Ramesh
  3. Steve
  4. Luke B. c/o Ramesh
  5. Luke
  6. Arden

• One definite requirement of this event is that we must have at least twelve drivers.
• The other 6 (numbers 7-12) drivers and teammates for the top 6 names and not necessarily in the same matching order.

• 1. Alex
  2. Jon
  3. David (Boo)
  4. Marlon
  5. Gary
  6. Dion

• The other 10 possible (drivers) names ... (* not 100% sure ...) maybe others and even who I don't know about

• 1. Douglas*
  2. Jonathan
  3. Kerwin*
  4. Kyle*
  5. Mark H*
  6. Nathaniel
  7. Nicholas E*
  8. Paul*
  9. O’Brie*
  10. Tony

Going over this listing of names - sure all FRC regulars will understand what I'm suggesting for this special event with LMP-E & GT-E Teams/Drivers ...

Mind you - still not sure what sort of interesting game plan selecting/picking out team-mates

I believe that we'll get the six cars. I also believe we'll get twelve drivers.

However if we get a few extra drivers and we want to include them, some teams will have three drivers. In this case, we will have to come up with a fair way to utilize them (fair to the teams they are added to and fair to everyone else). We will also have to have a minimum of two driver changes per team.

[Luke]

A-Okay GG,

Now you just have to let us know, what direction you're going in (officially) setting-up these endurance cars ...

Which one of these (a, b or c) settings you believe will be the best way to go after with all the deliberating done so far ..

A.

• • Minimum Ground Clearance: 1.0 mm / 0.040 in.
  • Motor - GT-E/LMP-E: Up to 21.5K & 25K rpm respectively.
  • Magnets - GT-E/LMP-E: Maximum Magnet Marshal downforce of 200/275 gms.
  • Car Minimum Weight: 90 gm.

B.

• • Minimum Ground Clearance: N/A
  • Motor - GT-E/LMP-E: Up to 21.5K & 23.5K rpm respectively.
  • Magnets - GT-E/LMP-E: cars must not be able to magnetically adhere to a standard track piece upside down.
  • Car Minimum Weight: N/A

C.

• • Minimum Ground Clearance: N/A
  • Motor - GT-E/LMP-E: Up to 18K & 21.5K rpm respectively.
  • Magnets - GT-E/LMP-E: cars must not be able to magnetically adhere to a standard track piece upside down.
  • Car Minimum Weight: N/A

You will notice that section C. has very low rpm ratings compared to A & B because remember this BLT with my ...

• • Scalextric GT-E Chev C6R - 18K rpm motor ....... 120 gm downforce ...... Rubber tyres - BLT 7.9 sec.

... and with some fine tuning at this (18K rpm) rating sure it may get closer to a round off 7 seconds.

Which you would like to see with best lap times around 6.0 sec for LMP-E and 7.0 sec for GT-E as an ideal situation.

Luke

[gordon]

Luke, your "C" suggestion looks very interesting. I have to think about it a bit and also perhaps prep a GT car with these specs to see what times it does.

[Luke]

Hey GG,

Its just me, being the support I have always been and I believe I just convinced you to stop thinking about using the 2 down force readings

In reasoning - sure you could compare section "C" to FRC/2-Hours (Race Report #166 - June 2014) Special Event.

You will notice that these cars (yours and mines) with same 21 & 18K rpm readings - were doing lap times of .5 seconds apart.

• • Gordon ...... Slotit - Ford GT40 @ 21.5K rpm .............. BLT 5.872 sec.
  • Luke ......... Scalextric - Ferrari P4 @ 18K rpm ........... BLT 6.388 sec. and to be exact a gap of 0.516 sec.

Although the cars were Slotit and Scalextric brands ...

The "upside down" magnetic rule wasn't in forced till 2015 and I have a strong feeling with these motor ratings and the new magnetic rule applied to setting up cars ...

• • Magnets - GT-E/LMP-E: cars must not be able to magnetically adhere to a standard track piece upside down.

It will be very possible to get the overall "steering" lap times and that 1+ second gap you looking for at this event.

I will also go and set-up a LMP-E car to try and satisfy one's conception with a 21.5K rpm motor testing for a BLT of 6 seconds.

Records in black and white ... for all to remember.

Testing done with these (Gordon, Steve & Luke) type cars.

Its just for the record ... plus heard Ramesh saying, he will tune a car for each class.

_________________________________________________________________________________________________________________


• Luke's Scalextric GT-E Chev C6R Corvette

• 1. Motor 18K rpm ................ 120 gms downforce ...... Rubber tyres ......... BLT 7.9 sec.

• Steve's Scalextric GT-E Audi R8

• 1. Motor 21K rpm ................ 180 gm downforce ....... Silicone tyres ......... BLT 7.1 sec.

• Gordon's Slotit LMP-E Audi R18

• 1.Motor 20K rpm ................ 191 gm downforce ........ Silicone tyres .......... BLT 7.0 sec.

• Luke's Scalextric LMP-E Porsche RS Spyder (84 gm) - plus applying the upside down magnetic rule ...

• 1. Motor 18K rpm ............... 239 gms downforce ...... Rubber tyres ........... BLT 8.2 sec.
  2. Motor 18K rpm ............... 216 gms downforce ...... Silicone Tyres ......... BLT 8.1 sec.
  3. Motor 21K rpm ............... 213 gms downforce ...... Silicone Tyres ......... BLT 6.2 sec.

Data like this, will help going forward to make a decision with the official/final slot car regs ~ building/tuning LMP-E and GT-E cars.

Although, with Gordon's lap time - not outright sure because didn't actually see recorded times on the power base. I did actually race the Audi R18 (doing test laps on the circuit) with my Porsche RS Spyder car and it appeared to be doing faster times than 7.0 seconds.

So I may stand corrected

For anyone wishing to prepare a car to test to help us finalise the class regulations, here are the current guidelines:

• Body (both classes): Body must comply with General item 2. Windows may not be tinted - interior must be visible.
• Body (LMP-E): LMP cars produced from 1976 onwards.
• Body (GT-E): GT cars produced from 1982 onwards.
• Interior: At least head and shelf.
• Motor (LMP-E): Up to 25,000 RPM
• Motor (GT-E): Up to 21,500 RPM
• Magnets: Upside-Down Rule (UDR) - no added weight ahead of front axle

Based on the results of these upcoming tests, we'll fine tune things. Remember, our general objectives are for LMP-E times around 6 sec GT-E around 7 sec.

[steveaca]

Is it that we are now going with the Upside-Down rule or are we still deciding between Upside-Down and Magnet Marshal ?

[Luke]

Hello Steve,

I believe if fine tuning things is going to be done afterwards, that will help determine the Upside-Down or the Magnet Marshal rule ...

Although, I think you should be looking at the (21.5 & 25K) RPM readings instead, which could be the decider for the general objectives of LMP-E and GT-E times.

Being part of the solution ...

Luke

[gordon]

Luke is correct there Steve. Let's try the UDR and run some tests. If this doesn't work as we'd like, we'll go back to the Magnet Marshal. The thing is that if the UDR works, it will be easier for everyone to set up their cars.
