I would not trust TRD on that. They claimed 165 crank hp on a corolla/matrix with SC, but in real life we were getting 159-160 wheel hp with the blowers. that's 20% error right there. Good error, but still an error.Originally posted by Kwiksilver@Dec 7 2004, 10:43 AM
i don't think anyone knows the real answer to that. trd should give factual numbers.
I know this is off-topic, but I had to address your comment about computer hard drives, Kwik.Originally posted by Kwiksilver@Dec 7 2004, 12:01 PM
it's kind of like computer hard drives. the computer specs might say 180GB but it is really 168GB or something like that. they round up, by a whole lot.
I doubt you could get any gain by changing plugs. I've only seen power gains with plugs when the original selection was so poor that the engine misfired badly. Not enough to make you say, OMG, it runs like crap, but enough to kill your fuel mileage. The engine comes with Iridium plugs intended to last 120k miles. That's awfully hard to beat.Originally posted by Pharohz@Jan 17 2005, 08:05 PM
Thanks. I appreciate a quick reply. I guess I'll just stick with a CAI for my first upgrade This might not be the right thread for that question, but should I change spark plugs and wires to get an hp gain, or would that mess up factory settings as well?
I'd be SHOCKED if the trd exhaust gave more than 2hp.Originally posted by QuadinScionTC@Jan 17 2005, 09:21 PM
why are you wondering how much HP exaust gives you? Stickers will pump it up much faster... like 10 HP per square inch or sticker. But really the exaust might give it 10 hp MAx... but dont quote me on that.
