I have a 1990 ZR-1 which i drag race sometimes. I made a "cold air" intake system for my car. Using the old A/O engineneering cold air kit I cut a larger hole into the front bumper
( 4in x 3in ) and fed the ambient (outside air) into a closed air housing using the stock air filter.To help reduce heat into my system I placed Alu bubble sheet between the radiator shroud and the bottom of the stock air filter. Also warpped the stock air filter assembly with DEI cool warp to reduce engine compartment heat out of the stock air filter.
Not sure if this helps but my car has run 11.54 @120 in the 1/4 mile and 7.52 @101 in the 1/8 mile. The car makes only 418 rwhp.
1990 White/Black #2546
one of a few 4l8OE transmission eq ZR-1's

The front plate is one I made and sold about 2 years ago.the plate was cut out
so outside air goes into the air filter and screen helps keep out paper. trash and slow cars. with this setup I get 20 miles per gal at 70 mph on the interstate and about 16 mpg around town.

A little off topic.... What 60' times are you running with the automatic?
Do you still have the engine oil cooler? I've been considering removing mine as my oil temps rarely pass 180* and I wouldn't mind slightly warmer oil temps.
My 60 ft times are from 1.60 to 1.68. I launch at 2500 rpm foot braking. compushift controller shifts car at 6800 rpm (1/4 mile) 6500 rpm for (1/8mile), Tires are M/T street drag radials. I have switched my drag tires from M/T to Nitto Same size 315/17 i'll see if this helps when I got to the first points race at OSW in Jan. 2025.

still have all equipment from factory, except for the transmission

Reason: missed question about oil coller
