Hi guys. I don't get here much during the week. For some reason my work server blocks this site. I had to post about my first quarter mile runs since installing the LT4 Hot Cam and RPM Air Gap Intake.
I've been fiddling with the fuel injection and ignition timing since I put this LT4 Hot Cam and RPM AIr Gap manifold in two months ago. I think I just about got everything dialed in so I lower the 295s to 30psi and I put $20 of Premium gas in the tank and head out toward the beach.
My first run I engine braked and launched at 2000rpm. The car just sat there forever spinning the 295/35-18s. I shifted at 6500rpm, and more tire spin. The car pulled really strong in second and third especially about 4000rpm. With a very bad launch I almost matched my best time with the old cam and intake. 13.06 seconds @ 114.4 mph. I was determined to get into the 12s today, so I turned around and did it again, this time into the wind. Tire spin again and a very late shift into second scrapped this run for sure, but it was a fairly decent 13.7 something. This early Holley Fuel Injection won't support redlines above 6500 rpm and it won't rev past. I didn't even bother to write this time it down. At least by now, the rear tires are warm. I turned around for run 3, again with the wind. I only power braked to 1500 rpm, barely above idle. But when I released the brake and buried the throttle, there was no tire spin. None, nada. I short shifted at 6000rpm this time trying to avoid the mistake of my second run, and again, no tire spin, no chirp. The car was hooking and moving, and again at 4000rpm it pulled like never before. In third gear the tach needle swung toward redline. The car is only good for about 140mph in 3rd, so I was reaching for the shifter. I never had to do that in the 1/4 mile before. But just before shifting the G-tech flashed and I backed down. I was hauling ass but I didn't know how much till I saw the numbers on the G-tech.
11.50 seconds at 135.8 mph. HOT DAMN! SHOOT! and Mother Fuddrucker.
I was shaking, so I drove the car home and put it in the garage. I don't smoke, but I need a cigarette. I need to go out again tomorow and see if it will do it again with no wind. I wanted in the 12 second club and jumped right into the 11 second club. I won't claim membership untill I repeat, this just seems too good to be true. But I trust my G-tech.
I love this car. I guess this cam works really good with the AFR 195s, the RPM Air Gap, and three inch Flowmasters. I was thinking of going to 3.7 gears in the rear end but I don't want to have to shift into overdrive in the quarter, so I think I'll stick with 3.55s..
