...to enhance 91-93oct pump gas?

Racer friend swears by Torco. E85 is not readily available at or near most popular tracks in North East so evaluating fueling options for built engine @ 20psi boost.
Pros
- reduces knock in high compression high boost engines.
- need relatively small amounts for good gains, 100oct.
- 30% cheaper than buying 100oct at track.
Cons
- leaves orange-ish residue on spark plugs and exhaust, does not appear harmful.
My current HPDE consumption with 93oct + 13psi JR C38 HBP + 5gal per 30min session + 4 x 30min sessions/day = 20gal/day.
For each HPDE day:
- @ 13 psi boost - 4x32oz Torco ($80) + 20gal 93oct ($60) = $140 for 107oct.
- @ 13psi boost - 2x32oz Torco ($40) + 20gal 93oct ($60) = $100 for 103oct.
- @ 13psi boost - 20gal 100oct bought at track = $200.
- @ 13psi boost - 20gal 93oct bought at track = $60.
- @ 20psi boost - 6x32oz Torco ($120) + 30gal 93oct ($90) = $210 for 107oct.
- @ 20psi boost - 3x32oz Torco ($60) + 30gal 93oct ($90) = $150 for 103oct.
- @ 20psi boost - 30gal 100oct bought at track = $300.
- @ 20psi boost - 20gal 93oct bought at track = $60 with lowered redline to max out boost to 13psi.
Unit costs:
$21 for 32oz Torco can if purchased in 6x32oz package for $120.
$15 for 32oz Torco if purchased in 5gal drum (same quantity as 20x32oz) for $300.
Pump gas 93oct rounded to $3/gal.
Track 100oct rounded to $10/gal.
Cost/gallon at $21 for 32oz Torco (box with 6x32oz cans price):
$15 for 5gal of 93oct + $10.5 for 16oz Torco = $25.5 for 5gal = $5.1/gal of 103oct unleaded.
$15 for 5gal of 93oct + $21 for 32oz Torco = $36 for 5gal = $7.2/gal of 107oct unleaded.
Cost/gallon at $15 for 32oz Torco (5gal drum price):
$15 for 5gal of 93oct + $7.5 for 16oz Torco = $22.5 for 5gal = $4.5/gal of 103oct unleaded.
$15 for 5gal of 93oct + $15 for 32oz Torco = $30 for 5gal = $6/gal of 107oct unleaded.
Looks like handling 32oz Torco cans would be more convenient than pumping from a 5gal canister, also considering Torco is sensitive to light.
Will be interesting to measure power and fuel consumption when JR RS pulley increases boost from current 13psi to 20psi at >100oct, together with new injectors and pump.
