What does HO stand for???

I just purchased a 99 Grand am gt ho, what does the ho stand for??

High Output(more power)

what makes it an ho? like whats extra in the engine

nothing. Theres no 3400 LO engine, so an HO version really cant exsist. Its just marketing. But if you look at the old Quads theres the LO which made 150hp then theres the HO's which made 180hp. the difference between the two is the HO has different pistons different head cams and computer tweaks compared to the LO quad

so is the ho faster than say a reqular gt?

and for ur info. my g'am is a 3600 not a 3400

there is no such thing as a 3600. lol sorry GM just doesnt make one. but no the HO is not faster then a normal GT, b/c there is no normal GT. There is a GT without ram air and one with ram air. And the difference is about 5hp.

it says right on the engine 3600

take a picture of it. GM never made a 3600. there was a 3100 3400 3300 3800. Take pictures of your whole car i want to see this.

well i dont have the car here right now, but i do have a full body picture in my gallery. Tonight once i get the car ill take a pic of the engine where it says 3600...

im waiting to see this 3600 that was never made. wheres it at?

A 150-horsepower 2.4-liter twin-cam 16-valve 4-cylinder engine comes standard. An optional 170-horsepower 3.4-liter V6 offers substantially more power than last year's 3.1-liter V6. All Grand Ams come equipped with electronically controlled four-speed automatic transmissions.

im waiting to see this 3600 that was never made. wheres it at?
HAHAHA Hey, I don't know the truth, or who's right but I think it's funny as hell when people get busted over stupid ish that they lie about on cars. I think it's hilarious. I got this Mischeif 3000 Racing DVD, and in the specials part, It's got this "Domestic Ricing" chapter, and it's this guy with this 2000 Mustang with GTR on the back where GT is supposed to be. But it looks exactly like the skyline logo. And the camera man is messing with him... and the guy said it stands for a special model they only made in 2000. And the guy was like "you got a turbo in there", and he said yeah "yeah" Then the guy asked him if it was rotary in there. And said "oh yeah", with "headers right?", "yeah yeah full exhaust". I was dying.

My :2cents: :2cents: :2cents:

yea i saw that on the net. hes like rotarty pistons, lol supercharger turbo. good shit right there. i wish i could find it agian

Yeah I got it on this DVD, and I don't know how to get it on the internet because I can't save it to my computer, or don't know how. But I got it burned on a cd-rw as data straight from the dvd to the disk, that worked but i dunno. Anyway WHERES THE PICTURE, LOL :rofl: :rofl:

yea i think he was making it up and now hes afriad and doesnt want to say anything. I want him to prove me wrong with his made up 3600

Yeah man welcome to AF, there's always funny stuff arund here, just look in different forums.

BTW- Still no pic huh?? Mabye his keyboard broke when he was tryin to log on to tell us his camera broke. LOL, Characters... :smokin:

or maybe he cant read all that great and cant read the keyboard well enough to type on, that would explain him thinking he has a 3600 in his car.

dude where is this picture. PROVE ME WRONG!!!!!!!!

i ended up not getting the car

well go find it and take a picture of this 3600 motor, that you were so sure was in the car. lol

how about you just go fuck your self, its not that big of a deal anyways.

Well Then No need to get all Hostile about it, if it wasn't such a big deal.

I just purchased a 99 Grand am gt ho, what does the ho stand for??
i ended up not getting the car

Did you or didnt you buy the car, you say one thing then another.

and for ur info. my g'am is a 3600 not a 3400

it says right on the engine 3600

how about you just go fuck your self, its not that big of a deal anyways.

you seemed so sure about it, you where so fast to correct me even though you had no idea what you where talking about, makes me think it was a big deal to you.

but really i want to see this motor, you were soooooooo sure about it so i want to see it.

BTW next time you correct someone know your shit.

Here is a 3600. But he said he had a 99.

Is the HO the DOHC?
OHV = 175 hp
DOHC = 215 hp

So my guess is the twin cam 3400, (looks like a hemi)
would be the HO. That's just my guess.
I just got a 2002 GA GT /w 3400, and was disapointe to find it only had 175 hp. I was reading about the 3400 having 215 hp, but was disapointed when I foung out mine didn't. Why does anyone even make a OHV anymore? The car I traded in for my GT was a dodge /w a 2.5 L /w 165 hp. Single over head cam with four valves per cylinder. I didn't get why jumping almost a liter only gave me 10 hp more. And that's with an extra 5 hp frome the Ram Air. Then I realized it was OHV. (Over Head Valve is old school) The valve train uses to much power. Just think what a 350, 360, etc. would do if it where DOHC. Even the single (SOHC) cam with four valvle per cylinder. I read years ago that the OHV design uses about 100 hp on the old V8's. Look at the 3400 /w 40 more because of the DOHC. What's up with Detroit????

BTW, The Right Formula, I know someone just like you described on the video. Actually I know of 2 poeple like that.

well since the car he purchased/didnt purchase is a 99 it has the 3400, he doesnt seem to know anything about cars, which would make me think he would never have swaped that 3.6 into his car (and that is not a 3600, they just dont exsist)

the 3400 HO is just a marketing ploy theres not LO of the 3400 to make there be a HO. the DOHC your talking about is in the olds minivan i think, along with the pontiac minivan.

I know I saw pictures of a GA GT that the guy found out it was one of only about a thousand or so, so he pute it in storage for the winter and bought another Grand Am that was much less expensive, and I saw a picture of the engine, and it was a DOHC 3400 /w 215 hp. When I saw that, I felt like I got ripped off. I wanted to 215 hp engine in my car. I'm going to try to find those pictures of that one. Maybe leave a measage here with the url. When I saw the pictures of his car's engine, my first thought was a HEMI! Yeah!

Well The DOHC V8's Have extreem potential, BUT they are expensive to produce, They are really big, they would have to be made of entirerly Aluminium. They Made a LT-5 Corvette engine which was DOHC V8. I think it made 415?? Not to sure though. Porsche has a DOHC V8 that is really nice. makes about 315 HP 316TQ. Most of your Race engines are OHV engines anyway. You can eliminate most of the Friction and loss of power from the valve train by going to Roller Lifters and Roller Rockers. So it is in all reality cheaper to go OHV Than OHC.

Those are upgrades I don't want to mess with untill after the warrenty is up.

OK.... the 3600 is not in any Grand Am past present or future, there is no 3400 DOHC, but there "WAS" a 3.4 TDC (twin dual cam) available in W-bodies for a few years. 215 sounds about right for the hp ratings.

So what's the difference between the 3.4 and 3400. They are still the same size aren't they? I didn't find any difference at the fallowing site.
http://www.60degreev6.com/
But they were listed seperately.

while they both are essentially the same size, 3.4 liters and have the same piston angle of 60 degrees. The 3.4 TDC motor is a overhead cam designed engine while the 3400 has an Overhead valve design.

Do you have any links that I might be able to see this? Over head valves are still pushed by a push rod? If so, than it's still the same? I don't have a repair manual for this yet. I'm sure I could see the difference in the book.

Well, the 3.4 TDC has 4 cams total. There is one exhaust and one intake cam shaft on top of both of the cylinder heads. In this OHC setup, there are no pushrods, the cam lobes acually push the valves open.

On a pushrod aka OHV engine there is one camshaft at the bottom of the "V" that controlleds everything. The lobes of the camshaft push the pushrods up therby openingthe valves

I'll look for a picture or a website that explains it all for you :)

This site does a good job explaining it, and has some good animations :)
http://auto.howstuffworks.com/camshaft2.htm

OK, the TDC through me off, that DOHC per top of the V, making basicaly a Dual Dual Over Head Cam, since it's a V with two heads. Two cams per head. (Quad Over Head Cam) (QOHC) So my 3400 is still the old pushrod design. (eventhough it's the newer engine) It only has 23,000 miles and is about as noisy as my Saturn was @ 200,000 miles when starting in the morning. Quiets down when it warms up.

exactly, you got it. TDC stands for "twin dual cam" not my word, just some crazy name GM thought up lol. The 3100 and 3400 engines can be very noisy when they are cold, thats because the pistons expand. so Gm designed the pistons to be smaller than the cylinder bore when it is cold so that when they warm up they are a perfect size.

Great. Thanx for the info. I was going to have the dealership look at it. Guess I don't have to.

They probably won't do anything about it since it doesn't really cause any problems, but I believe GM just issued a recall because some 3400s and 3100s have a severe case of this "piston slap" so if it annoys you, then take it in, the worst they can do is tell you that its normal.

u know whats up there is no 3600 i got a 99 ga gt ho that other guy that says he got one or that he didnt have one he all bs 99 ga gt has 3400 ho with ram air i thought the same thing to about horsepower i thought it had over 200 but nah but u know that ga guts up and goes i was just reading some stuff that u post im having problems with sunroof thats all but my ga runs good other than the dam sunroof but oh whell it is an american car hahahaha c ya laters.....

the old z34's had those 3.4 twin cams , lots of balls but had lots of quirks. The ports on the new 3.4 12 valve internal cam setup are pretty big for the engine dispacement and provide excellent air flow but still allow for more if your any good with a die grinder and manipulating plastic gaskets evenly. Still ported out , not as much port displacement as the twin dual cam but closer and less moving breakable parts so more reliable durable hp can be produced. Also takes very well to turbo's without compression changes and takes very well to dry nitrous kits so long as you have de-icer for the throttle body. You only need to do light midifications to install a heavier nitrous kit (heavier valve springs and nitrous specific plugs) you could easily use a 10lb bottle in a day and the car most likely run fine after. sorry im off topic. But i have seen HO's on the 99-up grand ams and they are still an la1 207 12 valve v6. I think they have a bit different cam or something.

everyone's wrong, HO stands for "Hold the onions"

the only difference between 3400 and the 3400 "HO" is the ram air setup. GM claims 5 or so extra HP form the Ram air, but I don't beleive it, it just a marketing ploy.

So, even though my car doesn't say it's a HO, it still is? I have the Ram Air. I thought the HO was on the quads with the high performance additions, and, of course, the older V6 with twin dual cams. With my home maid PVC CAI, I do notice a difference though. Small, but it's there.

BTW, I was looking at my car the other day, and I noticed, even though my engine is a 3400, the white sticker still says 3.4L. So I'm guessing the new 3.6 could be considered a 3600. I know it doesn't back up what brots06 was saying about a 99, but it would be nice to throw that under my hood.
www.60degreev6.com

IN 199 Pontiac used a badge on the front quarter panel that said "V6HO" or somethiung like that, In 2000 (I htink) they changed the Badge to "Ramair V6" the ngines are the same its just a badge change.

3600/3.6L does not exist...trust me. I work at a GM dealership and i think i would have seen one by now..I think this brots06 person is just retarded and is trying piss everyone off. And the ram air only works at high speeds, hense the term "ram air" and i think it is a waste of a good idea. If your going to ram air anything then stick to the V8's with factory 250+ hp

Yes I agree about brots06, but did you check out the 3.6 VVT @ http://www.60degreev6.com/index.php?p=sections&sid=31 ?
Yes, I would like to have a V8 with RWD on this car. I'd have to get the new GTO if that's what I want. Have a family & need the 4 doors.

This is vague, but it mentions the 255 hp V6 http://www.automotive.com/Reviews/09/2004/cadillac/cts/index.html

I do believe the 2004 Cadillac SRX and CTS are a GM product. If I'm wrong let me know. I'm not to proud to be wrong.

yes the 3.6 is in the SRX and CTS.

yes the 3.6 is in the SRX and CTS.
well get your shit right..it is the 3.5L vvt..i know this because i worked at the engine plant in st catharines. there is no 3.6/3600 dickface

I beleive this should be enough proof of a 3.6 VVT (variable valve timing) engine.
This is only to prove there is one now. Not to support the start of this thread about a 3600 in a 99 GA. The 3.6 is new for 2004. The fallowing site shows that Yes the 3.6 VVT is made @ St. Catharines

A 10 hp boost could be quite insagnificant, hard to notice unless you compared times at a track (run with box off then do a run with it on) I also heard those boxes are junk and when i investigated the product it was extremely vague on vehicle aplications. No graph or chart or dyno tests shown.

Me GA has only 10 hp more than my Stratus did. I notice a big difference. Maybe it's just the torque. I don't know what the torque rating was on the 2.5L V-6 Dodge engine. Later on after I put in on, I read about how a 50 cent resister @ Radio Shack doe basically the same thing. When I e-mailed the company about it, I never got a response. When I told them I didn't notice a power change they would respond, until I mentioned the resistor trick. It only makes the engine run rich. I didn’t notice less power when I turn the box off, but that's only because the computer has adjusted to the reading it was getting. I'll have to try timing the 1/4 mile some time. No track around here though. Just out @ the intersection out by the farming fields, and to the white shack on the side of the road. It's 1/4 mile.

yeah I know, he called me a "dickface" so I figured the only way to get him to listen was to call him a childish name in return

I wanted to say something other than posting those links to prove him(88international88) wrong, but I didn't want to sound like him. LOL
I tried to be polite about it.
