If you read the Vorshlag blog,.....I gained a measly
100 LBS and kept the exact front to back bias......since then I have lost even more weight by removed A/C compressor and condenser.....removed all air bags and wiring....Stereo speakers and wiring etc.etc...(track car)..but a
100lbs gain with the same balance for a trade off of 372whp and 465ftlbs of torque on pump gas NA is all win to me.
* Vorshlog before correction on weight bias....but total weight gain is unchanged *
The initial car came to us at 2682 pounds (no back seat + 17x9" wheels + roll bar + race seats + front BBK) and with the LS1 + T56 it is now 2816 pounds, for a gain of 134 pounds. I'm a little surprised by that amount of gain, honestly, because my initial best-case estimate of a 50 pound gain wasn't that accurate. Some of this gain is added fuel weight; the car came to us with less than a gallon of E85 in the tank, and now has a 1/3rd of a tank of 93 octane - maybe 35 pounds more fuel than before. So the real gain from the LS1/T56 Magnum XL swap was about 100 pounds.
