Subject: RE:Help with 91 L98 Performance Mod's by bogus on 2005/10/23 17:03:19 The L98 has a ton of performance available to it. If you have the cash, and you really want to keep up with an LS1 equipped 98, it will take cash. you are 100hp short, and a generation of chassis behind! I would recommend the following upgrades: performance cam performance heads super ram intake This would cost a lot of $$$, no doubt, but with exhaust mods and a stock bottom end, you would be in the 350hp range in no time flat. Seriously. The throttle response would be insane, and, with a higher torque peak, it would be a much more drivable and launchable engine (too much torque too low would cause the tires to toast and you don't do anything that resembles forward progress... that would suck :D) This is the problem... the C4 is a GREAT chassis, but it is now the old chassis, and to make up for it, we have to have more power. The C5 can get it's power down better, we can't. There are other things you can do to the chassis, disconnect the sway bars helps, I have been told. Oh, one last thing to consider... gearing... if you have a stock automatic L98, it is more then likely a 2.59:1 rear gear ratio... I would upgrade that to at least 3.31:1. Better yet, if you have the $$ (about $2k), I would upgrade to a Dana 44 with 3.45:1 rear gears. Whatever gearing options you use, don't go about 3.73 with the automatic... beyond that, it really doesn't work well. If you have a manual, go with 4.10s and really rock!!! If you have an automatic, a torque converter will help, too. I don't know enough about them, so I suggest you search around CF or check with the various TC manufacturers, or, call summit racing. They have experts who will really help you make a good selection. I hope this helps you get an idea of what it will take.... Oh, and practice your driving skills!!! |
