...and you wouldn't get any more knock running the stock airbox/snorkel.
The original "290bhp" Cup fuel/timing mapping done by Snobeck for the 1990 Cup series in France are knock-safe, even in very hot weather, but that is when running a stock K26/8 turbo, not some Garrett/KKK hybrid with, I assume, a different compressor map, which seems to be your case.

CUP K26-8 is NOT same as K26-8 1989, this is confirmed that the hot side has bigger wheel, yet my 1989 cold side has larger milled to fit Garrett, true mine is not exactly Cup Turbo with my Cup Chips.
290hp seems low with 111oct, 18psi . The goal is making torque with velocity rather than big flow with Lindsey Stage II head, my 3" test straight pipes, 3bar AFPR, cup fly, cup clutch, KEP pressure plate and Quaiffe LSD, 18" twists, to put that torque down to rear wheels.
I'll get a dyno before and after C02 sprayer.
Now the stage 1 C02 fuel bar would reduce detonation ? Drag racer cheaters use soup can and copper lines and dry ice to cool the petrol.
Also have stage 2 CO2 section between oiled cone and AFM witch measures ambient temp unlike my old MAF 3.
I saw some guys with big IC install temp guage on the IC pipes.
I think the IC inlets is the major CFM restrictor. But with all that changed, the TB is still stock and is said to be 130% as big as it needs to be already.
I think I'm squeezing nearly all I can from this hybrid k26-8 and flow matched stock Bosch inj.
So I'm focusing on the intake reconfig and IC.
Curious what C02 would do to engine, since the cone is behind radiator and IC sprayer, I've never sprayed at WOT for this reason, it would prob like Nitros but that stuff is combustible and cost 3x more than C02 from a welder and uses different tank flange. Would it just rob HP or choke the motor if 5 second C02 blows over the cone @ WOT ? PCA guys debate inert gas and physics all day, many opinions, I rather just relocate the cone behind the LR headlight duct so I can hear the spooling whistle again, or would the flapper silence that in any location ?
How were your physics grades in school ?
