Ours is full strength year round. Highest my motor has ever calculated, regardless of season, has been 80%.What is the actual ethanol %age during the winter over there? In NYC it stays under 55% til March or so.

What do you use as your intake? Maybe the engine heats the intake assembly? Use gold heat reflective on the air intake surface, that faces the engine?Took my wife to the track last night in Orlando. It dropped into the 40s while we were there. Seems that every clunker in Orange County showed up, we arrived before race time and got only two runs by 10 PM so I called it quits. Slick tired cars were dropping oil and coolant and crankshaft parts all over the track. Same for motorcycles. A Ferd Mustang busted a universal joint at launch and had to be pushed back.
This time and last time I was hoping to break a record with the 3.73 gears. She did get her highest MPH on these latest runs but ET was close but did not exceed the previous best.
This time and last time I was watching the inlet air temps while staging and running. While it was 55 to 41 degrees outside, the air going into the motor was never less than 75-90 degrees even after sitting for over an hour, sometimes almost two with the hood up!
Over the years while driving, the truck's inlet air temp would climb into the triple digits while idling and take a few minutes to get at or just above ambient temperature once out onto the highway.
Should I take the intake off the throttle body and air everything out while waiting to race? Volant did make an air scoop, they still make them for the Sierras.
As usual, I launched from idle in 4WD and then switch back to 2WD at the end of the 60-foot. I was thinking of leaving in RWD or power braking the truck and launching at a higher rpm. All the delays changed that. Maybe I should break out the VC2000 and look for a deserted road? Think I said that already! LOL
Anyhow, first pass was best pass at 16.136 @ 86.86 mph weighing 6,400 pounds burning E85 @ 80%. That's 324 RWHP.
It's just the stock factory intake with the larger air filter, A3085C. Somewhere in the garage is a thin K&N air filter that I bought for it before learning that it didn't like dirt roads.What do you use as your intake? Maybe the engine heats the intake assembly?

In past older vehicles, I used a 'heat reflective' .... peel-n- stick, 2" wide, aluminum surfaced, 1/8" thick 'spongy insulation'...... wrap.Took my wife to the track last night in Orlando.

So would I use that tape around the base of the airbox? Maybe the top too? I miss the air scoops we had like yours!In past older vehicles, I used a 'heat reflective' .... peel-n- stick, 2" wide, aluminum surfaced, 1/8" thick 'spongy insulation'...... wrap.
I used it under my '88 truck's air cleaner to reflect heat. ( Here's the air cleaner, but can't show the underside )
I sold it with 392,000. The reflective wrap never got loose.
I would think, for the underside, to reflect the radiant heat.....Then, I can only guess, leave the upper alone to cool off after your Bonneville run....So would I use that tape around the base of the airbox? Maybe the top too? I miss the air scoops we had like yours!
That looks like about 3/8" or 1/2" thick..... If it's peel-n- stick, you can cut it to manage the surfaces you encounter.
That one is listed as .20 inches thick.That looks like about 3/8" or 1/2" thick..... If it's peel-n- stick, you can cut it to manage the surfaces you encounter.
Maybe Summit might have something, also?
