Well, to get to 200, you're probably going to need headers

good luck dude, horsepower doesnt come as easy as you think.
you may hit 200 at the crank, with all that stuff and exhaust, but i dunno.

And figure 200 at the crank is about 150 at the wheels.
I guessamate I'm putting 206 at the crank. I could be wrong, I did a really rough figure via 1/4 time and weight

i seriously dont think there's 25% loss through the drivetrain... though i could be wrong, someone else care to chime in?

no, that is more or less right. It is disapointing how poorly our cars respond to performance modifications. 200 crank = 150-170 at the wheels depending on the car.

i could see 170-180 at the wheels with 200 at the crank, thats with engine/tranny mount upgrades.

The generally accepted rule of tumb is 20-25% power loss through the drivetrain for most vehicles. Of course it varies from vehicle to vehicle....

yea... advertised expected gains and stuff like that are all speculations....
you'd be lucky to get about 12 hp i'd say.

HP doesn't work that way. It's not as simple as saying "this adds 12 HP, this adds 8 HP...."
Not to upset you or anything, but this is the truth. I would also say that with the pulley, CAI, and exhaust, you might gain 15 HP. Each car responds differently. I just don't want you to have high expectations and then not achieve them. To break the 200 HP mark with our engines, you really need to consider headers. They make the biggest difference.

Do generic filters on WAIs destroy your MAF like the oil on the K and N filters? Have alot of people had there MAFs destroyed????

good question, that's why i'm afraid to change mine.
i had a k&n kill my maf, at the time i didnt know what was wrong, then i switched to CAI, and well after that was "broken in" i swapped my maf.
i'm still looking for a filter that isnt oiled (all metal) or one that isnt oiled that you oil yourself.

well im pretty sure i keep my car in very good condition, i dont drive it too hard, i clean the engine as often as i clean the car, but anyways that borla cat back says it give a 10% increase in hp, and 10% of 170 is 17. and if i cant trust a WAI,crank pulley, and exhasut, then i might as well get a DHP PCM, that will unleash the WAI, and exhasust potential a bit. so yeah $720+ just for some pieces of metal......maybe another day :P

if you're refferring to headers, they're the one upgrade that will actually make a difference, well aside from forced induction.

in certain situations you will get advertised gains, but what we're saying is that everything works together, and it doesnt just add up with each bolt on.
they may put headers on a car that is supercharged with all kinds of other mods, and get another 12hp out of it. but that doesnt mean you're gonna get 12 hp... understand?

yeah, but this engine seems more and more like an engine thats meant to be stock. cause it seems like you could spend over $1000 (not including headers) and only get 5 hp.............lol it just seems to me that things you can buy for the 3400 engine will provide .3 hp or .6 hp. i mean its like, whats the point.......lol i hate to say it but this just doesnt seem worth it. so how bout this- AN ENGINE SWAP. anybody know info about engines that could fit the alero, i know that there are northstars, shortstars, etc. i just dont know anything about thier price or performance. but anyways do you guys think it would be better to switch to like a 2.4 or a 2.2? i mean they make alot more things for the engine, and they're alot cheaper. just give me your input, i'd appreciate it
