Weight Mods...What You Think?
Weight Mods...What You Think? I had some ideas to remove some weight from the car and gain some hp up top. since my car has become less of a dd I was think of dropping some weight from it to see if I would get any real gains from it. First I was thinking of going with 23.5in long 3" dynomax bullet mufflers straight from the header collector with turndowns. This would mean zero backpressure from the exhaust and some free ponies up top in the power band but it would also mean a delete of the big 3" xpipe, the over axle muffler pipping and mufflers. The Hooker mufflers I have are at least 30-40lbs each. The mufflers plus all the pipping I figure should mean 80-100lbs. Also my ac comp went out a while ago, I have to remove it any way to reapir or replace it so why not just keep it off for now? Its been really cold and I went without it this past summer anyway plus its what, 30-40lbs? Im also looking at some Sparco and Hunsaker racing seats that should be lighter than the stockers. So, what do you guys think? I drag race and track the car but Ive been setting it more for HPDE and autocrossing. Also lets jsut say that loudness and no ac are not an issue for me already. That car is high compression with a big cam so Im use to noise. So would I be able to notice 150-200lbs off the car and the more free flowing exhaust? Btw, I shouldnt see any real "torque loss" down low with the new exhaust. The length of the headers (32in primary) should provide the necessary exhaust scavenging effect and no back pressure is always good. Also I weighed the car in at 3220lbs as is.
As long as your track/venue doesn't have a decibel limit, I don't see the issue as long as you don't have clearance problems.
Lower weight will help in all aspects especially for road racing/auto-x. Less mass means less force needed to do the same job as before. That means your engine, trans, suspension and brakes aren't having to work as hard to pull off the same times. Granted that you're also good and consistent behind the wheel.

Yeah I'd definitely lighten the car
Also by removing the Ac condenser from in front of the Radiator
My car runs much cooler ,
A lighter car accelerates quicker, Transitions faster, and stops quicker

Good idea about the condenser. Thnx. LS1s run on the warm side as it is.
I dont see any mufflers weighing 30-40lbs though.

Verdad Gallardo The Hooker Header mufflers do weigh that much each. They flow good and sound good but they are heavy. I'll weigh them after I remove them.
I have a Stainless Steel Corsa and between the Muffler, Piping, and Tips, I can certainly tell you its at least 30 pounds, possibly more. JL been trying to get me to ditch it. Not quite yet....
I'm somewhat surprised to see EGT's like that in a header that small... usually, when you go to an egt/cyl setup like that, you're making in the 1000+ hp range, and certainly in a place that you'd benefit greatly by putting a set of larger primary headers on..
