So here is the deal. I took my car to the drag strip a couple times about a year ago 3.31s 305/45/18 tire. 620rwhp. I would consistently max out 3rd gear rpm hit the rev limiter a bit before the end of the drag strip would trap 125.6 mph consistently. It was cooler weather. Best time with this setup was 11.81 at 124mph with a 1.98 60ft. Which was hot lapped literally, got off the track and back on.
I installed 3.73s and thought for sure I would pick up some more mph in my trap since I was hitting the rev limiter.
Nope it went down highest trap was in the 124 range with crappy 60 ft 2.0-2.1 spinning. Best runs was probably 12.1 if i remember correctly.
Switched to M&H 275 45 18 drag radials. Love the tire hooks quite nicely. Best run was 11.57 with a 1.88 60ft trapped 123 mph. This was in warmer weather.
Last night went back to the drag strip cool night low 60's, now this is where I am confused. I just spent a stupid amount of money on modifications. 2.4 pulley, port matched elbow to vmp tvs, 67 mm throttle body, ID1000's, PNP dual boostapumps, and a 1 piece driveshaft. Horsepower is unknown right now. My best trap of the night was a 124.4mph ran a 11.60 with a 1.92 60ft I bogged off the line. Next pass 25 min cool down waiting in line to run. Trapped 123.6 ran 11.51 with a 1.84 60ft.
Now with all that said my gears have whined from the beginning of being installed. That is a whole other story. Would that affect performance this bad if they were not installed correctly? This new tune is stupid rich right now. I just figured it would of picked up a decent mph with it all said and done even though it was rich.
Any thoughts/ opinions are welcomed.
Thank You.
