Turbo chargers?

Sorry, I took off for the week....

Anyway, Streetracer:

Turbo lag is not an issue with a turbo that is matched for your macine. Would you take a marine turbo and strap it to a car? I thought not. Use something that will match your output.

Lag is also not an issue because you run at the highest rpm's while draging all the time after startup, so this really isn't an issue.

Poetic:

If you choose to go low boost, and decide to maintain stock compression, you CAN install your own turbo setup. They generally are a true bolt on affair. If you lower the compression, get a shop to do it, when they put back together the engine, it will be easy for them to add, and won't cost much extra.

As for time, you could bolt on a turbo in a day (no compression) and a shop would take about the same or longer (depending on wait) If you lower the compression it would take you a couple days - a week (depending on skill) and a shop would take a couple days.

Bolt on turbo's require this:

remove old manafold, (6-8bolts) attach turbo manafold w/ turbo already attached. remove injectors, add new injectors. Plumb oil line to turbo, attach ducts, attach bracket to rad support, attach intercooler, finish duct work.

It wouldn't take you much time if you have the right tools: 1/2" socket set, allen key set.

Time is cut in half if you have air tools as well.

Think about it: unless this is already a turbo engine, you're re-routing the intake and exhaust, adding & moving a few sensors, you might have to replace the exhaust manifold (depends on the kit you buy)...it's a lot of stuff going on. Even installing the turbo itself can be tricky, trying not only to wiggle the components in & out, but making sure they join correctly. And having the metalshop to fix it if they don't fit. :-/

This does not apply if you buy a kit, as listed above. Everything will fit and be a true bolt on. Hybrid turbo setups is where you run into trouble.

Not speaking for Deathawk, but I think he means picking out the specific components yourself, rather than some package where everything has already been determined to fit together. I guess he's right, you could do a turbo kit yourself, but you'd need some familiarity with what's under the hood.

The other meaning for "hybrid turbo" is changing the specific components of the turbo itself. For example, IHI can sell you their VF30, a good bolt-on replacement for the WRX, but you can change the housing, the impeller, etc., to substantially change the performance aspect of the turbo (that's the stuff I consider voodoo...because I don't quite understand it fully). :)
 
I was reading that thing about turbos on www.howthingswork.com, and they said that to over come turbo lag some poeple use 2 turbos. A big one and a small one. The small one for the lower part of the power band, and the big for the higher part of the power band. Can I do this on the civic? Or should i just stick with just one turbo?
 
1. Hybriding is generally used to define a turbo that has an exaust turbine that is different manufacture (or size) than the impeller. If you use a small turbine and a large impeller, if it is matched properly, you can get more boost out of a smaller turbo with less lag.

2. I couldn't think of something better to define it at the time... Hooligan was right...

Anywhoo... dual or twin turbo's are only used on systems with six or more cylendars. It will not help you to have 2 turbo's on the I-4 because it wouldn't provide enough boost (w/ 2 small turbo's) and the lag is acceptable with 1. Six cylendar engines, benifit, because they can have 3 cylendars feeding a small turbo, and 3 otjhers feeding a larger one, basically, once the small one runs out of boost, the larger one is spooled up enough to pick up the tab.

Of course there are other applications that use more, one being the eb101, that has 4 turbo's. Unfortunately, they did a ****ty job of setting it up, so it didn't work well (that's the problem w/ 2turob 4cyl) so it never made much power, and the delivery was pretty much on off power wise. This is all happening on a V12, so turbo's can basically do what you want them to. On marine applications, they run one large ass turbo, which will drive everything.

So in other words, ONE turbo.

I have a great serise on this, (turob's) from SCC magazine, but I am missing around 5 issues from their series "Suck squish bang blow." You can order the backissues, which will cost you around 100$ (or so) for 10 good issues of SCC which will answer this and many other questions that you are going to be looking to be answered ( :odd: did that sentance make ANY sense?)

Anywhoo, it is late, and I am tired.

Also, if you can't get me to answer here, drop an email or PM to me... I will always check those.

Yeah, there's lotsa good info in the SSBBs, right from how engines work to calculating turbo size. I've got them all, and I heard they might release them as a book when the series is done...
 
Do you have access to a scanner? Would you be able to scan the All the articles? That way, with people asking me these questions, I can just give them a copy of the articles?

PM me.
 
My second day in school and I don't dont think I'm going to be able to make the grades I need to get this car. Its alot harder than I thought it was going to be.

I have it too. I wanted the "Suck Squish Bang Blow" set because they covered turbocharging in 11 different issues, that went WAAYYY in depth.

I will see what the superstreet one had. Any info is good info.

2ND DAY!!! You are losing hope after 2 days?! Just keep plowing through... You will eventually achive what you want.

Your grades (depending on the subject) mostly come in the last half of the semester.
 
DH, no access to a scanner. Sorry. Not all 11 were about turbo either, just the last half or so.

I made the mistake of buying the Super Street 'Suspension Tech' issue a few years back, only to learn that: "lowering your car too much can actually HURT performance." :rolleyes: Wow, thank you Stupor Street. That was the last SS I ever bought...

In my english class, we had this summer reading thing due and I didn't do it. I was out of school for some reason for the last 2 weeks of school and I didn't find out what books we were supposed to read. And the school never sent anything home about it either. My teacher wont cut me any slack about it. She was like "You know we had summer reading". I didn't know we had it. And none of my friends ever said anything about it. So now I'm out points that would have made it easier to get the higher grade.

If she won't budge, talk to administration, take it up with your guidance councellor. Technically, they arn't allowed to give you summer reading. But whatever.

Well they are... But usually the don't as they have no powers as your teacher during summer break. We don't get them, because we get different teachers each year.

Take it up with administration. Mention that you have discussed the situation with the teacher, and you feel that what she is doing is unfair as you were not at school the last 2 weeks to recieve the assignment. Usually, though, a teacher is good about excusing assignments like this.

The same thing happened to me but they give us the assignments two weeks before school ends. My family went on vacation just before the gave out the assignments and when i went back to school at the end of summer i got a zero for a two test grades (a test grade counts twice) so that was like getting 4 zeros. I managed to bring my average up to a B+. I tried to complain but they told me it was my fault for not getting the assignnments earlier. Whats more is that that was the first summer reading assignment i've ever gotten so how would i have known about it. The whole deal pissed me off. :mad:

I've found that most teachers that teach advance or honors classes are like that.
 
depends. I like Superchargers more. More low end power and torque, and also most take regular unleaded gas(as opposed to Premium unleaded). Also they are smoother and there is very little waiting for it to start giving more power. Sounds good too!
 
Superchargers have more of a whine sound(like the racing trans in GT3, except it starts over). Turbos have more of a wistle sound.

As much as I've heard anyway(based on Millenia S(supercharged) and MX-6 GT Turbo and FD RX-7 Twin Turbo)
 
Turbo chargers don't put a strain on the engine and they don't rob power from the engine.

Super Chargers don't have any lag and they don't need as much maintainence.
 
Turbos do put a strain on the engine. Anything forcing more pressure into an engine will strain it to a certain amount. Ofcourse they don't rob power...but turbos take longer to make the power, and aren't as quick off the line.

I've been in a Millenia S floored from a stop, it's got all the power as soon as you hit the gas. On MX-6 GTs, you get the power boost at 3K rpm....
