Your Questions About Four Into One Exhaust

March 25, 2013

John asks…

Should I part out or sell my 1976 Honda CB400F project?

Hey, I just picked up a nice un-modified 1976 Honda CB400F (the one with four headers going into one exhaust) I payed 80 bucks for it. It’s all there, engine turns over, a little rusty / dusty with a few small dents. It does not run, i’m guessing the carbs are gunk’d up. So… Any idea what its worth? Should I keep it or part it our on ebay. (I’ve got a quite few projects… I’ll get to them I swear…I Think…)

Administrator answers:

Don’t part out the poor thing unless you think it is unrestorable. Sweet little bike, shame for it to get chopped up. Sell it whole.

Joseph asks…

Procharger-Wondering if I can run one of these on a chevy 350?

I bought an 85 Iroc with a 350. The motor sounds built with a pretty beefy cam. I don’t know what the compression ratio is because the prior owner has vanished. The motor is gear driven, and has stock exhaust. Has a four barrel carb, with edlebrock intake. The car pushes pretty good. I have never had it dyno’d.

I would like to install a procharger, but I don’t know what the compression ratio is. From what I understand that is pretty important to determine exactly how much boost you can run.
I don’t want to tear into the motor because the motor is tight and run well. I wanted a procharger so I would not have to do many mods to get HP. How can I find out what the compression ratio is without tearing into the motor., and how much hp can one squeeze out of 350 with a procharger.

Administrator answers:

You HAVE to lift the heads to accuactly determine the comp ratio.
If it good now, why stuff with it, enjoy it untill it needs rebuiding, then get stuck in

the power obtainable is directly related to the depth of your wallet. Remember, going fast cost money

William asks…

Don’t give up the one you love…? Long, but life choices need to be made x.x?

I have a sort of dilemma. It stems mostly from the fact I’m 18 and have a strong potential to be engaged soon.

I just started college this year, and there’s this guy, we’ll call him “A”, and he and I have a kind of past. We dated my junior year of high school, broke up when our religions clashed and he got to possessive of me, and we didn’t speak for a year. He always treated me well, except he would get moody if I didn’t do what he wanted (like sit by his side at the beach instead of swim, or stand near the wall instead of dance at prom), and he would get incredibly jealous if I talked highly of another guy (such as one of my many good guy friends). Needless to say, when he went off to college at the start of my senior year, he got anxious I would meet someone else while he was gone. So he drove a state over from where he was going to college to basically yell at me in my driveway for me talking to my ex (who was also a good friend at the time). I threw the gifts he gave me at him and told him to leave. That’s when we first broke up, and we didn’t speak for almost a year.

I casually saw a few guys my senior year, went to senior prom single, and then me and A started talking over the summer, before I went to college.

By October we felt we were in love again, but we weren’t sure if we could handle a LDR, so we waited until winter break to see how things went (we had tried an LDR for about two weeks but mutually ended it). By the end of break we were dating, and basically, he said he could see us being married some day and I felt the same at the time…so we were unofficially “engaged,” unofficially because our parents would kill us if they knew (since I’m 18 and he’s 19). He was in MA for college still, with me being stuck in CT.

Then I got a job, on my college campus, at a sandwich shop. And I met another guy, we’ll call him “K,” and he’s got an attitude and a strut and thinks he can boss anyone around, despite him being a lowly student worker such as myself. And he gets away with it because everyone loves him…because in reality, he’s a sweetheart who wouldn’t hurt a fly. He drinks like a sailor though, and although he’s never come into work drunk, he still parties late at night and comes into work exhausted. I loathe drinking but he has a hold on it apparently. And recently my boyfriend and I started arguing over everything, from my working longer hours to pay for tuition (where he feels like I’m ignoring him) and my feeling he’s too clingy (because he still gets crazy jealous at the mere mention of another male). Needless to say, as much as I loved my “fiance,” I’m newly single.

I’d be able to see how things with my “crush” K go, except I’m torn between K and A…and if I date anyone while on “break” from A, he says he’ll never date me again. Ever.

But I feel like I’m to young to be in a hyper-committed relationship. A has his life planned out and is following it to a T; he’s a sophomore in college, with a major in chemistry and a minor in math. He’s tailoring his studies to work for Phizer (a huge science/pharmaceutical company) one day, and he wants to own a place in Cambridge, MA with me as his wife. He knows my deepest secrects and fears, and wants the best for me…whereas K, he’s more laid back…he parties alot, and is a 5th year in a four-year college…but he also has a steady job, an apartment, a car and aside from his overactive social life, he seems to have his act together. So we just met a few months ago, he doesn’t know me all that well, and he doesn’t know what he’s doing in terms of an actual career…but at least he appreciates I have my own life.

There’s a saying, “don’t give up the one you love for the one you like,”…but what if the one you love comes off as a clingy control freak at a time when you want/need your own space and freedom?
I know the “engaged at 18″ thing sounds really dumb but A’s family traditionally gets married soon after high school, so that’s where the pressure on him comes from

Administrator answers:

Honey – you’re 18…

You’re out of your mind to even be thinking about making a committment to anyone but yourself.

And “T” is a jealous, insecue, immature, clingy control freak. He shouldn’t even be part of the equation, since he’s not worth being with anyway.

Nancy asks…

I Rebuilt the top end for a motorcycle and i have ran into a problem?

I Rebuilt the top end for a 1982 Honda xr250 around a year ago an went riding on it for one day before the piston cracked, it had been smoking pretty bad out of the exhaust since i rebuilt it but i didn’t think anything of it an then this week i rebuilt the top end for a small four wheeler an ran into the same problem it smoked real bad then the piston cracked while i had it on a stand just letting it run in neutral. Does anyone know what i may be doing wrong?

Administrator answers:

1.Where did your piston crack at? Across the top, between the rings or down the skirt? (side)

2. Was there ever a clicking noise when you started the engine? If so you may have had the timing chain off a tooth and allowing the valve to strike the top of the piston. Causing, the piston to crack on the top, and or bending the valve stem. Also causing the valve to open to soon or late.

3. No clicking noise, then you may have had the rings in upside down causing them to slip up and down inside the ring grooves, and therefore breaking the piston, and letting oil up into the combustion chamber. Hence the smoke.

4. By upside down I mean if you look at the rings they are flat on one side and tapered on the other. Also if all the ring ends were lined up, this would allow oil and compression to escaped along side the piston. Oil causes smoke on the ignition cycle, and escaping compression would blow by the piston wall and could aide in cracking the piston on the skirt, and or piston ring land.

5. The piston ring land is the little area between the ring grooves. Easy to break off if the rings were not installed properly.

6. Always install the ring into the cyl before you put it on the piston, therefore you can measure the gap at the ends where the rings come together, to much gap bad rings or to small of rings, no gap the rings are to big for that application.

7. The best advice though is, get a book on it. Or let a qualified mechanic do it for you, it’s actually cheaper in the long run.

Brian Power Question?

Five Associates stray off course during The Expedition and find themselves in a new Quest where there is nothing but a pile of molecules and the Avatar. Exhausted from playing all eight Quests to gather Cognizant’s DNA, the Associates agree to wait until the next morning to divide up the molecules.

At one o’clock in the morning, the first Associate wakes up. He wants to set aside molecules to be used to help his community, and decides to take his share now. He divides the molecules into five equal piles, but there is one molecule left over. He gives that molecule to the Avatar, hides his molecules (one of the five piles), and puts the rest of the molecules (the other four piles) into one pile.

At two o’clock, the second Associate wakes up. Not realizing that the first Associate has already taken his share, he too divides the molecules up into five piles, leaving one molecule over, which he gives to the Avatar. He then hides his share (one of the five piles), and puts the remainder (the other four piles) back into one pile.

At three, four, and five o’clock in the morning, the third, fourth, and fifth Associates each wake up and carry out the same actions.

In the morning, all the Associates wake up and again agree to divide up the current pile of molecules. No one makes a remark about the diminished pile of molecules, and no one says that they’ve already taken their share for their communities. Instead, they divide the pile up into five piles, for the sixth time, and find that there is yet again one molecule left over, which they give to the Avatar.

Administrator answers:

Here’s an approach that can give the ans instantaneously !
——————————-
ans: 5^6 – 4 = 15,621
——————————-
approach:
————–
let n be the number of associates
& p the no. Given to the avatar each time

let the no.of molecules at start be x
can there be a value for x which is such
that it remains unchanged after iteration(s) ?

For that to happen,
(x-p) – (x-p)/n = x ……[ give p to avatar, take own share, still x remains ]
which yields x = -p(n-1)
for p = 1 & n = 5,
x = – 1*4 = MINUS 4 molecules !
Start: – 4
give 1 to avatar: – 5
take 1/5th share: – 5 – (-1) = – 4 !

How does this crazy figure help ?
Let us take that the 5th associate left 5y – 4 coconuts
we know that the – 4 part remains unchanged
SO THE COMPLICATING AVATAR
IN EFFECT GETS REMOVED,
AND THE REMAINING CALCULATIONS ARE A CINCH
so 4th associate left [5^2/4]y – 4
3rd associate left [5^3/4^2]y – 4
————
1st associate left [5^5/4^4]y – 4
original pile [5^6/4^5]y – 4
minimum value of y to get an integer = 4^5
and original pile = 5^6 – 4

general formula: n^(n+1) – p(n-1)

David asks…

my girlfriend’s family?

My girlfriend’s niece is having a birthday party. She didn’t know what time it was going to be, but I said I would go last night when she asked me. Today she calls me around 3:00 to tell me the party is going to be at 5:00, and that she is getting off work at 4:00 instead of 5:00. In addition, her niece had a bigger birthday party the day before (on Saturday). My predicament is I work and go to college from Wednesday through Saturday, and drive about and hour and a half to stay at my uncle’s house during this time. I got to her house around 7:00 PM yesterday and spent time with her and her mom, and didn’t get to my house until about 12:00 AM, where I went to bed pretty quick. I pack everything into those four days, so I am pretty much exhausted when I get home. I also have my own family, (my brother and his girlfriend) who live at the house as well. I spent the morning setting up a wireless router and doing a few other things that needed to be done, and haven’t really had a chance to relax. Now my girlfriend is upset with me because I’m not sure if I feel like going. I’m not a super social person, and I get more social interaction then I would like during week. By the time I get home, sometimes I don’t feel like being around anybody. Also, I don’t know how long the party is going to last, because no one can tell me that. Sunday is my only real day off, because even though I’m home Monday and Tuesday, I have an online class to keep up with. I just need some advice because I’m really torn here.

Administrator answers:

Honestly it seems like that’s your only day to relax some & your girlfriend should understand that.
Just wish her niece a happy birthday when you see her next, maybe ask your girlfriend to give her a card..
You should really stay home & relax because with a busy schedule no time to yourself is a bad thing.

Lisa asks…

Auto dealer wrecked my car during repair. What are my options?

I took my 2002 Subaru WRX, which was otherwise in excellent condition (75K well-maintained California-driven miles), in for a repair to the heating system — it was leaking exhaust into the cabin. Somehow, during the repair, the tech dropped a washer into the fuel line and it got into one of the cylinders, scoring it and thereby destroying the engine.

The dealer gave me a loaner and replaced the engine at their cost with a junker that had 60K miles. Within half a day after getting the repaired car back, the check engine light came on. Then my battery went dead. I brought the car in and they found that the alternator hadn’t been tightened down during the engine replacement. They did a fix and then found that my brand-new battery had been drained. They did a partial recharge until I got frustrated and demanded to leave after waiting patiently for almost 6 hours with my 1.5 year old son, being told all the while to hold on, that it would be another 30 minutes.

On the drive back home, the check engine light came on again. I brought the car back in. They said I should have the spark plugs replaced, which I did at my expense: $225. After getting the car, the check engine light came on the next day.

I drove around for about a month with the check engine light fluctuating on and off every week or so. I wanted to see if I could make a more accurate diagnosis about what was going on. Also, I wanted to check the miles-per-gallon performance, and indeed, saw that it had deteriorated by almost 25%.

I brought the car back in. After 4 hours, again with my son (I’m the primary care giver), they said the computer indicated that a fuel injector was probably clogged and that they would replace it at their cost. But then they said that my gas was dirty and that they would have to flush the gas tank. They gave me a loaner. Four days later, with a clean tank and a new fuel filter, the car was ready. My expense: $913.55.

I did some grocery shopping and drove the car home. Along the way, the check engine light came on again. By that time, the dealership was closed. Over the weekend, my spouse took the car shopping with our son (the car seat is in my car and isn’t easy to swap in and out). I got a panicked call saying the car was billowing something that looked like steam. After limping home, it was obvious that the coolant system had sprung a leak. Exact location unknown, but it looks like at the connection point to the engine block, which would be consistent with them not connecting it securely after mounting the replacement engine.

All together, this has been going on for about 6 months. Between waiting at the dealer, trips back & forth to the dealer, and my spouse’s time, we’ve probably lost 15 hours of work time. I’m an independent consultant, so time = $ for me.

Even though I don’t live in California any more, the car has more than 90% of its miles in California. Other than some paint chips caused by road rocks, and a touch of rust on the exhaust caused by 1 season of salted roads, the car is very clean.

I’m thinking of demanding they purchase the car at retail Kelly blue-book value. What do you think I should do? Do I have any legal recourse? Do I get my insurance company involved? What leverage do I have over the dealership?

Thanks for reading this long account. I look forward to some interesting suggestions.
Dealer did issue a 1 year warranty on engine from date of install. Worst case, I would expect the warranty to be extended to the time from which the last repair relating to this incident was completed.

Administrator answers:

Wow, I wouldn’t screw around with them at all anymore! I believe you have been more than patient!!! If you want them to purchase the car I’d tell them that is what you want. If they don’t, I think this would be a very easy case for ANY lawyer! If the dealership gives you ANY crap about anything you want immediately contact a lawyer and let the dealership know that is what you will be doing. Not only do I think a lawyer could get what the cars worth I would think they would also sue for your time. Sounds like an easy case if you decide to go that way! Good Luck!
