Last time I went to wsid, I ran 13.5 in my VT2 LS1 auto, fitted with full exhaust, maffless tune, OTR and on baldy 225 tyres.. No other mods. It was 39 degrees as well just before xmas. 60ft times were around the 2.1 mark, bit under, some over.. Slow.

Next to me same night a fpv GT335 auto ran a best of 13.03 with most runs in the 13.3s, so I was close even then..

Since my last outing, I've fitted a ls6 manifold (previous was ls1 manifold) and injectors, fitted a 3.46 differential ratio from a m6 ss vx and a ported throttle body. Also had the car retuned. The car feels a fair bit more potent..

With my new round of mods, some better tyres and cooler weather I'd be hoping to go at least a flat 13 or dip into the 12s.

Is this enough to keep a fpv f6 or fpv GT335 honest? A pretty equal run?
