I recenty purchased a bone stock '99 Prelude V-TEC base model w/ auto trans. I lowered it and added a after-market alluminum under drive crank shaft
pulley. Then I added on some headers & free flow cat. What I noticed is it changed the power band of the V-TEC but it robbed the mid range & top end power. i ended up removing the exhaust & went back to stock. Can anyone explain why this happened or was I supposed to upgrade something when adding headers to a H22A. Mechanicaly the motor was perfect before the perf upgrade.
There is 149k on the car. So far no issues with trans. fluid was clean when I got the car. I replaced the fluid anyway. I did use Honda ATF fluid. What does the trans have to do with exhaust robbing power from a motor anyway. With stock exhaust the VTEC runs perfect. Little sluggish on take off. then the first came kicks in till 4rpms then the 2nd cam kicks in till 7 rpms. With the exhaust almost the same except you can feel loss of HP's.
Okay, for your power issues: The 5th gen has a decent tubular exhaust manifold from the factory. Unless you dump some serious coin on a high-end header, you aren't going to gain much more than decibels. So basically, you're probably running a high flow cat sandwiched between a stock exhaust and near-stock header. That said, it's possible that you've actually added restriction, or at the very best, matched the stock flow. The best cat in the world isn't going to do anything when it's bottle necked at both ends.
Back to your tranny. Start searching the forum, and make sure you have plenty of kleenex. You'll need it for the tears you're gonna be shedding.
Whilst your searching you might also want to read up on the possible issues with running an aluminium crank pulley since they lack a harmonic balancer.
OK...So unless you do some serious engine upgrades like cams, head work and lower end work the headers doesn't do sh__ to a VTEC. What to you suggest for bolt on upgrades (if any) to increase power??

Automatics are horribly slow, and no amount of money will make them fast. This has been proven time and time again.

Pretty sure that various headers (plural ok here, but each car being a S4 only has one header) have been dyno proven to provide a gain even on an otherwise stock motor. Not talking anything that is basically the stock header, but just in stainless steel though.
To get the most though you need to tune and with an auto I believe you are stuck running piggybacks (just another of many drawbacks to an auto).

.
Vague? Compared to the OP not saying what header they fitted and that all headers have no effect. Just saying that some headers have been shown to bring some gains just by themselves. Specific examples weren't required. If anyone cares about the potential gains of various headers, they can search.
hey tee dot, why you such a dick? who cares if its v-tec or vtec? the guy obviously likes his car and just because yours is different and is a manual doesnt mean he wants to hear your jabs about how much his car sucks because its an auto.. be a more positive person and productively add to discussions with people who clearly enjoy their cars without your approval. he wasnt asking if you liked his car, he was asking a perf question. get lost.
lol! This thread is headed in the right direction...
I don't see any problem with his response. He just stated a fact: the automatics ARE slow and unreliable
But still it's not nice to disrespect people and their cars. EDIT : Just answer the damn question that people want to hear . I know certain PO people get on this hype
As some people like to say. Dyno will only help you out and prove that your loosing power I haven't seen any one say anything about getting dyno to prove if you have lost or gained power. You should work on it from there to find out wth is wrong. BTW I found out recently that my old SiR had 3 inch custom extractors on it and it gave my S Spec a run for it's money when I raced it with my friend. Yes the SiR was an SS

Helpful hint: The '' emoticon at the end of my v-tec vs. vtec statement let on that the tone of my sentence was meant to be taken in a good natured fashion. You can always get a good idea of the tone of someone's post by their use of emoticons. For example, if I use a & a emoticon when responding to you, you can assume that I think you are a dumbass fvcktard, which I do.
As far as SS vs. 5-speed trannys go, I didn't take any jabs at him. I simply made him aware of the ongoing problems with the SS tranny. Would you rather I just let him find out the hard way? Again, & come to mind.
Not everybody is content in the misspelling of certain acronyms, and blindly trusting in a mechanical component that's been a proven weak link. You're certainly welcome to continue skipping down that path like some half-retarded sheep, though!

1. emoticons are juvenile.
2. he's not asking your guys opinion of his tranny or car.
3. you guys can inform or give from your seemingly encyclopedic knowledge base of which cars "suck," in a more civil fashion and still get your point across.
4. if you're from "t-dot" as in toronto that would explain a lot.
5. if being a "sheep" means taking other peoples point of view into consideration before "telling them how it is," then sure label me a sheep.
1. So how old are you? Are you that insecure of your adulthood?
2. The nature of a discussion forum is that anything said is open for discussion and/or debate.
3. I didn't say anything about the car sucking, only the automatic transmission. Btw, is your car 5sp or auto?
4. I'm not from Toronto or any other part of Canada.
5. I could label you a few different ways. Probably nothing you're going to want to hear, though.
Cliff's notes: You're a real fvcking overly sensitive douchebag who is probably going to have a difficult time gaining respect around here. I suggest taking the whiny pussy-a$$ attitude somewhere else.
Didn't "Dimr" continually say you were from Toronto because of your name "Tee Dot?" This is strange because nobody else has accused you of being from canadaland

Perhaps he's back with a new alias?
^I was just thinking the same thing.
I guess we'll know for sure if he starts freaking about Catholics.
Swear at me all you like, I got my point across and so did you, albeit in very different ways. I don't want your respect, emote all day long. Whatever floats your boat. Looks like you've been around the block here with like 4000 posts so continue your annoying ways. Sorry if I got under your skin little guy. The end.

30 years old. Bought my Prelude new in 2000. Haven't owned it since maybe 2004. Have owned four bikes and several other vehicles. I can actually see my current TSX from the window of my office.
Don't worry about getting under my skin. I jump at the chance to point out someone's stupidity. Thanks!
And, for the second time this week, I could care less about my post count.
And, before I forget, what exactly was your point?
By your ranting, all you've accomplished for yourself is to be targeted by other members as a cryass little pussy. What actual automotive knowlege do you offer? You can't even diagnose a dead battery without calling a mechanic.

Tee Dot. You have a tsx? I want to see pictures of this tsx mmm It must be nice

Hahah my you get worked up. Isn't there a TSX forum where you can go and post thousands of times?
The reason I come here is to gain knowledge about my car, I didn't profess to offer any mechanical knowledge whatsoever. Is a certain level of automotive expertise required to visit a forum like this? I thought that was kind of the point.
Call me stupid all you like, I'm confident I'm far more educated and successful than yourself. Your argumentative, childish manner and the obviously excessive hours you spend on a forum dedicated to a car you don't even own prove that out.
I know you'll want to get the last word in so go ahead. Enlighten me. Throw out some expletives and unfounded judgments based on my 9 posts.
Accuse me of trying to get the last word? What, exactly, are you doing?
Back to the knowledge issue. No, you don't have to meet any prerequisite, but don't expect people to not jump on you for asking plainly stupid questions. For example: don't ask a forum what a certain noise is under your hood. Get off your lazy ass and find out for yourself.
Addressing my argumentative nature- Please reread this whole thread and then ask yourself who initiated this whole thing. I offered the op advice based on the experiences of Prelude owners over the past several years in regards to his automatic transmission. I also advised him in reference to his perceived power loss. Only after this discussion had run its course did you come in here like some pms'ing little teeny-bopper, crying about the possibility of hurting the op's feelings. Funny, he hasn't said anything about hurt feelings. Is it really necessary to take up your cross for someone who might actually not even care?
And finally, your financial success and education. Congratulations!
Personally, I work as an estimator for one of the largest and most respected commercial roofing and sheet metal companies in the country. We average between 20 & 30 million in revenue a year. I'm sure you're not impressed, but let me assure you, I do okay.
Dammit kids stop arguing. Enough BS in this thread. They guy asked a legit question which deserves an answer.

But he is asking how to make his car faster. I want to make painfully clear that automatic Preludes, no matter how much money you dump into them, will always be slow. There have been a hundred guys coming thru the NA/FI/NOS forums over the last 10 years which prove that point. Have you ever seen an auto car run faster than 12.x? I haven't. Some of those cars have thousands of $$ of crap on them.
If you really care about speed, you have to consider getting a manual, no exceptions. It's kinda the opposite of the BBC/SBC domestic world.

Taking this back to basics . . . speed is relative . . . so if he wants to make his car faster than it is, he can . . . I was hoping you guys would share some expertise on how to make the car faster than it is.
I have 2 Ludes - 1 auto for city only and 1 SH I drive far more. BTW . . . all this talk made me go out and hit VTEC in SS mode just to remind myself what it feels like . . . it is still pretty exhilarating in the auto . . . though the manual is on a different level!. . . the H22A4 is a helluva motor, period!

I don't really have a strong desire to part with it . . . it's paid for and still gets a lot of the typical Lude compliments . . . since I have it, I use it when I'm guaranteed to be in true stop n' go traffic.

Can anyone explain why this happened or was I supposed to upgrade something when adding headers to a H22A. Mechanicaly the motor was perfect before the perf upgrade.
Most of this has already been covered, but it's time to put a little Kronn into it.
1. It's VTEC, no hyphen.
2. It's aluminum, no double-L.
3. Remove the under drive pulley and go back to stock.
4. Header is singular.
5. It's not a free-flow cat. That would be a test pipe. However, there are high-flow cats.
6. The header you added is most likely garbage. Ask me about headers.
7. What do you mean, you removed the exhaust and went back to stock? Your post never mentioned anything about upgrading the exhaust, only the header and cat. Granted, both are part of the exhaust system, but not considered part of the exhaust itself. That would be the cat-back piping and muffler.
8. You should have dyno'd the car.
9. It's mechanically. This time the double-L is appropriate.
10. The best answer you are going to receive is this: Revert EVERYTHING back to stock and sell the chik-tranny-car. Put the junk aftermarket parts on ebay and/or craiglist. Purchase a masculine car. You will know it's manly because it comes with its own stick. Then do some research on which parts are good for your vehicle and purchase them. Before installation, put the car on a dyno. After installation, put the car on a dyno. "Tune" with a piggyback for better VTEC crossover, A/F ratios, and gas mileage. Or you can revert to OBDI and tune with something more complete.

I am loving your tsx tee dot. Thank you for the pics I wish I had one to drive around in sigh. I am too attached to my lude that I can't even park it in places that I think is unsafe I think I could park the tsx anywhere because it looks too sufisticated to steal most likely spelt that wrong don't eat me kronn....
