The competition at WSID is brutal there is a stack of cars in the 10s & 11s that appear fairly stock

It's funny I'm in the same boat. I test my 0-60 by my house on the street and I'm always faster and can launch harder , isnt that ridiculous? My best run of 12.55 in 1/4 mi on the track here in California where my 0-60 is .25 seconds slower that my best on street at my house. I could easily be at minimum of 12.25 if I could launch the same as on the street , that's just sad..

Lately I have been but judging by 60ft times don't see an improvement over just stepping on gas

Typically if you leave the car at idle when you whack the gas it'll rotate more and load the rear suspension better versus having the suspension already loaded.

Keeps reminding me I need to take the Jag out before it gets too warm.

I just fabbed up my own duals today. Added two 4” tips to better fill the bumper cutouts (making a large diffuser as well). This car finally sounds the way it should.

The Larini exhaust is all modular, I can remove it at a later time. My wife primarily drives the car, so I didn't want it obnoxiously loud. I love the tone of it, it doesn't get crazy until wide open throttle.
