Use the Search feature above to find what you're looking for. A cat-back exhaust system will help to some degree, but intake modifications don't seem to pay off. It can take a lot of money to get obvious gains out of it. It's a well-engineered system, so gains can be few and far between. If you want to spring for nitrous, that'll buy you a few HP. Get a "Type R" sticker for another 35 HP.CadillacETC1997 said:Hey lookin for some performance mods to do on my 97 ETC any ideas? So far im gonna get and run two Raven Mufflers and cut out my resignator.
LOL... Ummm, I guess it depends on what you mean by "work." If you mean, "Will it put money in the seller's pocket," then by all means, the answer is it works wonders. If, on the other hand, you want to know "Will it make my ETC go faster," then I think the answer is a resounding no frickin way. If Cadillac could boost the engine's power 10-15% by adding on a tiny electric fan, don't you think they'd do it? That would be some of the cheapest horsepower ever generated. This little electric fan will probably supercharge the seller's bank account, but I'm reasonably certain it will do nothing noticeable to your car or anyone else's. Put $110 in your retirement fund. It will be money well invested.CadillacETC1997 said:
What about a chip. I've read they are available for the eldo. My next car will probably be a newer eldo ETC (got a 94 now). And I was planning to do the exhaust, chip and nitrious.davesdeville said:You should be able to take an LS8 without any mods. The only worthwhile things to do would be cat back exhaust and nitrous.
Nitrous works the same on every car... there are different ways of running it but all involve injecting nitrous as well as more fuel into the intake tract. Search google for basic nitrous info, search the forum for northstar-specific nitrous info.CadillacETC1997 said:I already figured on the exaust kit but hows the nos deal work ive seen it on 98 sevilles how bout on a 97 ETC
