High 13s

[376shovel]

2003 marauder. Completely stock. Just bought a k&n fipk and a 93 octane tune from MO'S. I am looking to keep stock gears and go 13.90s. in the future I will be getting a 2.5 inch x pipe and high flow cats to replace the stock setup.

Tell me what it took for you to go 13.90s at sea level.

I went 13.72 with JLT intake, PHP intake spacer, 93 octane tune, 180 degree t-stat, NGK TR6IX plugs, GMS coil connectors, PI 3500 stall converter, deleted rear cats, flowmaster super 40 mufflers, stock gears and 255/50-16 drag radials. Ran a little less than half a tank of gas, pulled the spare out and pulled driver side headlight out. Track was 20 ft above sea level.

Before going 13.7x, my fastest was 14.35. Added the 3500 stall converter, drag radials and a tune from Zack is what helped drop more than half a second.

Video is of my 13.74 run. Later that day I ran 13.72.


After having my exhaust complete re-done from stock manifolds back, 4.10 gears, UDPs and dyno tune I went 13.63. Trans parameters were off in the tune and had converter issues. 150k on the motor as well.


Add 4.10 gears, 3000-3200 stall converter and you'll be there. Could also ask MartyO aka Mo what he would recommend as well. You'd need a 4.10 gear tune and adjustment for the higher stall converter also to take advantage of their benefit. Each car can react differently to mods, but most see around the same results.

Thanks. Not going to do a converter or gears though.

gears + headers + tune and then ------maybe.

this will create a serious challenge toward reaching your goal.

I guess I'll have to run it go see where I'm at. This is my new daily driver. I have another car I use to race. I just wanted to know if anyone has done it with 3.55s on here yet

I have JLT intake, rear cat delete with MagnaFlow Mufflers, NGK TR6 Plugs and Marty 93 Tune and ran a 14.58 on factory wheels n tires. Next mods will be 4.10 gears and SW Headers. Hope to reach 13.90's. If not then 75shot to get Me in 13s.

Did you do runs before and after those changes? If so what results did u have?

No, I never ran it when the car was factory but I heard they run anywhere from 15.3-15.5 stock if I'm not correct?

My DTR runs mid 16's with mods, we tried to do a video, but the camera operator fell asleep just waiting for the burnout to happen.

That low 14 high 13's appears to be the threshold for our cars n/a.
This is subject to lots of variables, so you "see level" guys , take it easy! Lol
I never got into the 13's without FI, the best was 14.2@97.XX
