thanx , last fri the temp was 90 deg @11.00pm and the da according to drag times was right at 3000 ft . we made a couple of changes to help the car launch we made a rubber snubber extention so there was only 1/4 in air gap and adjusted the coilovers so when the car was at full power going down the strip it was the shortest height wise . took a little fiddling , balso moved the air temp sensor to the air dam so i would get heat soak in the staging lanes . before last fri it was common for the air temp gauge to read 120 by the time i got to the line which killed the fueling and timing. now with ti moved it was reading 90-95 deg which was the temp at the time . we also plugged the vacume going to the fuel pressure reg . which help us get a little more fuel to help 60 fts . but launching a 420rwhp c4 6 spd is tricky at best .my best 60 ft was 1.83 with the new nitto nto5r drag radials , which are way better at least to me thatn the mt drag radials i had before . we are thinking we could really improve the 60 fts by either going to the 275 40 17 drag radials or go down to a 16 in tire to get a larger side wall which would help with the launch on a manual car. but if she starts to hook too good then i might start braking 1/2 shafts or stub axles . since i have to travel 190 miles one way to go to the strip i think i will just stay with the tires i have . sure is fun going to the strip in the zr1 as alot of young people think its a standard c4 till they see it run. after she runs once there allways seem like there is a bunch of people comming up and asking tons of questions .which is why my buddies named the white 92 Farrah , as she gets a ton of atten where ever she goes . where in texas are you located ,i have a good buddy corey henderson that has a great shop in new braunfells . he ported the blk car and tuned both the blk 90 and white 92 . he is a great guy to either do work on your car or tune it . he also owns a 368 ci 91 zr1 corvette that runs very low 11s. . i think so mkuch of his work i drove both cars almost 3000 miles round trip just to have him tune them. he even improved the gas mileage on the 92 ,on the way out she got 23.8 and on the way back she got 27.6 and thats with 3.92 gears . and i wasnt going slow on the way back as it was too much fun driving the car with the 27 more rwhp he found . if your close and want your car tuned right look him up once you meet him you will see what a grest guy he is that really does enjoy bettering every car that crosses his dyno . have a great week end
na i take my cars to the drag strip .last fri the 92 went 11,94 @117.90 mph at famoso in bakersfield . there vids of both cars on utube. under joeshmoe 12301230 fastest vid i have of the blk 90 is 12.10 @119.85 mph . eat your heart out
