First Good 1/4mile Timeslip

mastershake · July 19th, 2007, 12:03 PM

Made the trek to a good track yesterday. I was hoping for a 13.5#...
03 GT, auto, unbolted mufflers and 75shot. Everything else is all factory original down to the tires.

First run: Left at 1500rpm, 2.1 60ft, engaged nitrous at 3k rpm. Let off the nitrous at 5k rpm, then back into after the tranny shifts at 6k rpm.
13.63@104. Just what I expected...

Nows heres the good run:
Left at 1700rpm, 2.1, engaged nitrous at 2700rpm, chirped the tires when I did, Stayed on the nitrous the whole way down.
13.39@104.6

I never thought it would run faster than 13.5. I know I can get 2 more tenths if it would dead hook off the line, then I could also engage the nitrous sooner giving me at least another tenth. So roughly a 13.0

Just how fast do you think I can make this car go with getting into the motor? I could still do DR's, gears, converter, tuning, change the plugs and go to a 100shot.

Basicaly, Im not famaliar to the 4.6L, and am surprised at whats mine has done so far.

also forgot, it was around 80* and very humid, not good racing weather

03 R Code · July 19th, 2007, 04:47 PM

What's your rwhp at? If you got that 60' under control you'd see 11's no problem. I'm making 308rwhp and I'm running 12.6-12.8 with 4.30 gears exhaust bolt-ons and a tune...

You should be able to eclipse that with a driver mod and some stickies...

flattusmaximus78 · July 19th, 2007, 04:51 PM

Damn, your car seems freakish. You could be in 12's no problems with bolt ons and gears if you get your 60 foots down.

03 R Code · July 19th, 2007, 04:59 PM

It's a good rule of thumb that every .10 you save in the 60' will equate to .2 in the quarter. You ran a 2.1 60' so with a 1.9-1.7 you could see some solid 12's. Plus a 104mph trap speed would be enough to get 12's once you get traction.

orangeRcode · July 19th, 2007, 05:45 PM

You will definitely see 12s with some better tires. Good luck and keep practicing. Seat time will probably net you a couple of tenths without changing anything else.

mastershake · July 19th, 2007, 06:16 PM

I only got those two passes in, then it started raining, so I can go back again for free next week. Im currently building an 86 Cutlass, so Im probably not gonna go much further with the Mustang, but now I know it would definetly be worth it if I did. I'll see if a good burnout helps any. From past experiences with other cars burnouts with street tires have never made much of a difference, but its worth a try. Id like to be able to hit the nitrous at 2500rpm, cuz thats where it kinda bogs off the line. But if I do it might break the tires loose and send me for a ride like one other time.
Is removing the air filter worth anything? Its a clean track so nothings gonna get sucked up, nor have enough force to break through the MAS screen

03 R Code · July 19th, 2007, 06:24 PM

I don't think that will benefit you at all. Another easy mod is the passenger headlight removal. Just 2 metal tabs and unhook the electrical clips and POW, instant cold air directly to the filter.

flattusmaximus78 · July 19th, 2007, 08:50 PM

Also if I were you I'd put my mufflers back on. I have a mustang with now muffler and it def got rid of some low end torque, and maybe you
have noticed to. Being the lack of back pressure.

mastershake · July 19th, 2007, 09:16 PM

My engine is much much more responsive with the mufflers unbolted. Mabey it does take away a few ft-lbs in the low end, but it gains a few HP on the top end where the engine is reving when your racing, so the car does get faster.

flattusmaximus78 · July 20th, 2007, 10:20 PM

I feel the same way, but it could help with 60 ft's.

Ryan Paymaster · July 25th, 2007, 07:26 PM

Are you really looking at any real, noticeable gains with the passenger headlight removed? I have the K&N FIPK2 on my Cobra. I guess I'd do it if it netted me a tenth or something and I was on the line of putting myself into the 12 second bracket.

03 R Code · July 25th, 2007, 08:41 PM

I've ran my fastest times with the headlight out. It seems to make a difference in my car. Not anything I ever feel though. Just that I happen to have run faster when it was out.

04GTAMPA · July 25th, 2007, 09:26 PM

It should help in the higher range, cooler air.

My fastest runs at 2 different tracks have always been with the headlight out as well. Don't know if it is psychological but the theory is sound. More cold air to the filter.

ShapeShifter · July 27th, 2007, 11:00 AM

not too shabby, add some gears and drag radials and run 12's....ive run a best of a 12.4@108 on a 75shot, i spray off the line tho.
