LOL **** gas mileage, if my car car spin the tires through fourth I could care less about gas mileage. To receive power you must give up some amenities. I mean a 9 second car is obviously built for one purpose and that's to go fast, being a daily driver is secondary. When you say "9 second daily driver" it's not something you can really drive daily but it's something that it either street legal, or can be driven on the street when it needs to be or when you feel like it. Nobody builds a 9 second car to wear out by the rigors of daily driving. That's my opinion.

 

Gas mileage? You might lose 1 to 2 mpg by building a stroker.

Assuming 5,000 miles a year (that would be a whole lot for a 9 second car), a 350 gets 18 mpg, a 383 gets 16 mpg, and gas is $1.75/gallon, the yearly gas cost increase would be $60.77.

Compared to the $4000 short block, $2500 heads, $1000 valve train, $1000 fuel system, $4500 supercharger and intercooler, $1500 transmission (assuming 3 speed auto), $1000 converter, $2500 rear end, $1000 roll cage, etc. . . ($19000 so far, not including the price of the car), I think the gas mileage difference is a moot point.

LOL. yeah, i don't worry about gas mileage. I'm never off the throttle enough to get good gas mileage, so that doesn't even weigh in the equation. I understand about the almost same price for stroker situation, but what I was really trying to understand by this post is the science and reasoning behind the advantage of a 383 blower motor over 355 blower motor.
My big concern was about the lower revving stroker motor not working as well with boost when compared to the higher revs of the smaller ci engine, as well as the extra amount of flow that would be needed to create the same amount of boost.
It basically boils down to the same thing as buying a cam. Cams are all similarly priced, but if your cam does not fit with your engine combination, you've wasted your money. Thank you for all your input so far.

 

You keep saying lower revving 383 stroker motor. Uh I can spin my 385 to 7000 rpm and above easily all day long. I put the same blower pulleys on this motor off my 355 and lost 2lbs boost, But it's easily fixed by changing my crank pulley.

 

That's false. I'm not saying they are everywhere, but that is not opinion. That is false . There are guys that have cars that fast , and this is their TRUE daily driver. And some of them it is there ONLY car. The person I know that lives near me goes to school over an hour from here, and he drives to and from school with A/C and all. It's a late model z28 running 9's. It's a good motor combo, and nitrous. Yanks the wheels on the street or track. That is what boost, nitrous , cubic inches, $$$$ ,and technology are for. I have seen cars trap over 140 in the 1/4 mile, and drive over 300 miles a week. I saw a mustang that runs 10.5 at 143 on drag radials. The guy drove it over 300 miles a week. It was a stroker with a blower, and put down over 800 at the wheels.


Look at Jordons , car i think it used to be, and probably may still be a daily driver. His old combo ran somwhere in the 10's at over 136 in the quarter, which is 9 second power if it hooks. The z28 that I mentioned in my first post only had a 355 with a 218/ 230 114 lsa cam. That is nothing radical at all . Why couldn't you drive that every day???

YOU COULD. You say " it's not something you can really drive daily." Thats why I say it's not opinion but false, becasue people are driving them daily. That's not a matter of opinion. It's being done. Again, I am not saying they are everywhere, but they are there. And not trying to argue, just stating fact. The cam and combonations in my car and many other "slower" daily drivers on this board are bigger and more radical than the z28 i mentioned ,but the Z28 has a blower and good combination.

Look at INTIMIDS car . I don't know if it is , but it could easily be driven every day. This is 2003 ... Blowers , turbos , nitrous, technology, cubic inches, as well as $$$$ count for alot.

 

For a centrifically blown street car, you want to keep your rev range low, around 6 - 6.5k. Setting it up like this will allow the motor to last longer (due to less wear and tear from hi rev's), and give you a wider power band, which would be more fun on the street. Since the motor will make boost (power) proportional to rpm's, you don't want to wait till 5.5k to really get into your power range.

For an all out race car, it doesn't matter as much, since you'll have the rev's up high most of the time, and you'd probably be planning on freshening up the motor more frequently than a street car.

You don't use the revs of the motor to set your SC speed (boost), you just pulley the SC to provide the desired amount of boost at whatever rpm you want it to peak at.

 

There are apparently 2 misconceptions at work here:

1. A 383 limits the rpm potential of a combination. Not true. A 383 will fatten up the midrange and low-end alot, but not hurt top end.

2. A 383 reduces boost, and that is bad. Not true. If your engine flows more, then less air will be held up in the intake. Less boost will register on the guage, but more air will be flowing through the engine. If you want to register alot of boost, then leave the long block stock. You can make over 20 psi boost with a serpentine set-up on an S-trim. Or, you could do heads, cam, and stroker, and make only 12 psi, but double your power. Your choice. For any given compressor speed, it will flow more air if it is making less boost.

I'd like to point out, again, that a centrifugally supercharged motor inherently has an "all top-end" power band, with weak low-end torque. A stroker crank helps this poor power curve out by pumping up the low-end torque. And if you think low-end torque is not important at the drag strip, you are sadly mistaken. Once you get down to the low 11 second range and quicker, the 60' time is incredibly important. Low-end torque gets you a good 60' time.

So you are telling me that there is a significant amount of 9 second daily drivers? And I'm not talking about N20, that's cheating. I'm talking about real 9 second cars as they sit. They are just not practical enough to be driven daily. Most of the time, if a person can spend all that money on a car they have enough money to buy a 1500 dollar bucket to get them around . That's just how it goes, it's not worth all that money to put it to waste by daily driving it.

What I said before, a 9 second car is not meant to do anything but go fast. That's why it is a 9 second drag car. Being a drag car means the car is set up to race at the track. So you come flat out and say that is false? How can you even fathom that idea? A car that runs 9 seconds in the quarter mile is not a daily driver, it is built solely for the track. It was not built to be a daily driver. Show me a car that can line up at a stop light and run a 9 second pass as it sits with street tires and full exhaust etc. NOT HAPPENING. A car built to be a daily driver is a Honda Insight that gets 77 mpg, not a 9 second Z28 that gets 4 mpg. Great, if you know some people around your parts where fast street cars are not rare then go send them a cookie for me but if they drive their cars daily that is just not right. I mean unless they had ****loads of money to waste, it would not be economically sound to put thousands into a car and then gradually wear those thousands away driving that many miles.

So next time you say I'm false think about it because I always think before I speak. I swear some people on this board have problems with getting aggressive. Ever heard of the word DISCUSSION???? It's not a debate, it's a DISCUSSION. I never asked if I was true or false, I stated my mind.

----------------------------

As for the 355 vs 383, I know when it's time for me to rebuild I'm going 383 especially because I'm blown. You need that low end grunt because a blower will make it's max power at the tippy top of the RPM band. The 383 will attempt to make up for some of the lost area under the curve by giving it a low end kick in the ****.

 

this is why i brought up the gas mileage, bc some people DO build cars to be fast DAILY DRIVEN... may not 9s, but definately 10s can be daily driven and has been done. to me, i dont get the point of building a car that goes stupid fast once a week while you drive around in a piece of crap all the time. u dont have to get great mileage, but something in the teens to get around would b nice

any why is nitrous cheating? are slicks cheating? is using race gas cheating? bc i bet those 9 second drag cars are using those other things to get there in alot of cases but arent using that kind of thing on the street, so why not n20.

i merely bring these things up for discussion, bc not every1 has the same goals or plans to get there.

 

N20 is cheating on the street because it's not always there. Slicks are not cheating because they are tires and you don't have to press a button or open a tank to use them, you just drive. Race gas is not cheating because once it's in your tank it's stays there and that's how your car sits, with race gas. It doesn't come out at the press of a button... Lets not get into that though. The point of building a fast car to drive around in a bucket is just as you said, building the car. Some people enjoy the process of building it and have enough pride in it that they don't want to break it driving it as a daily driver. So you are going to sit here and tell me that you will spend thousands on a 9 or 10 second car just so you can daily drive it to wear it out and so that you can be ready the next time a mustang pulls up at the line??? I mean you are trying to tell me that you make a 9 second car to daily drive the **** out of it? I mean how often do you use the 9 second capability on the street??? Obviously not much unless you want to keep your license. That's why people have buckets or even nicer cars sometimes to get them around because it is quite obvious that a 9 or 10 second car is not a good daily driver for the reasons above mentioned and more.

 

without getting much into the n20 part, i drive around alot, and i could have a bottle in my car all the time, but i cant drive around with slicks on all day and i cant use $4/gallon race gas all the time either, so i just think its a mod like anything else. that said, im not a huge fan of n20 either, but its a means to a goal and an effective one at that

and yes i spend thousands of dollars on a car i daily drive the **** out of. why? because its a CAR, thats what its made for. i respect the idea of building a car that is for racing only, and for cars that are just for gettin from point A to point B, but id rather take a bit of both rather than all of one.

i have enough "pride" to build a car that can drive to school and work everyday, take on trips, and still go to the track to run a good time. doesnt mean im doing it so that i can be ready for some stoplight race, that doesnt interest me. but having the power around all the time is fun, and if im going to spend so much $ on a car, im going to make sure i enjoy it as much as possible

im not building a track car, i want to push the limits of what i can do with a college budget street car. then ill push the limits with a real-job budget street car, thats just my thing, and thats why i asked about the gas mileage difference, bc to alot of people it needs to be able to get 13-18mpg (or whatever) and still run a good time.

 

While I kind of agree that talking about gas mileage and 9 second cars in the same paragraph leaves me a little , I will say that the key to good mileage and a fast car is having a manual tranny with an OD. Last year I drove my M6 to the track and back (with the slicks in the car), bolted on the slicks, ran mid 10's, and drove home. A 110 mile round trip and I averaged (indcluding 4 runs) 16mpg! In a 3,500lb car, that combo would have run pretty close to the 9's and it sure could be a daily driver.

With the TH400 and a 4,200 stall, I averaged 9 mpg on a recent highway jaunt . So, I'd say you should stick with an M6 if you have any concern about mileage. As for a 9sec car that's a "street" car by my definition, keep one thing in mind: BRING $$$$$.

Well I still get max. enjoyment out of my car and I don't drive it every day. Things like going to school and commutes like that have no need for a 9 or 10 second car (or my car for that matter). It would be a waste of gas, waste of money, waste of car. If you have ****load of money then do whatever you want, but if I really had that much money I would buy a Z06... I mean let's be honest here, the more we mod our cars the more things can go wrong. A 9 or 10 second car is not a feasible daily driver.

I mean realistically you could drive a 10 second car every day but why? It just doesn't seem logical in the slightest bit to me. I mean go ahead and spend all the money on your car but you don't have to drive it to school and work every day to enjoy it. I mean it's not like it's serving a purpose sitting in the parking lot all day??? I mean that's great that you can drive your car every day, so can I. My maintenance record is perfect and I would take this car anywhere but why??? It's just a waste? I could easily travel 100 miles to the track, run a few times, and travel a hundred miles back with ease and I would do that because it's necessary. But why daily drive a really fast car? To me it's just a waste since most daily driving involves traffic, stupid drivers, tight parking spaces, and worst of all, cops.

 

First of all just by the first sentence in your post, I can see you don't read or listen. I said they are not on every corner, but they are there. So where do you come from with the question about there being a signifigant number of 9 second daily drivers??? I flat out stated the are NOT on every corner, but they ARE out there. Next , you seem to have this notion that just because you would not spend that much money on a car to drive every day that some won't. Some folks have a WHOLE lot of money. One of the mustangs I know of has about $100,000 in it, and puts down over 800 at the wheels. It runs over 140 in the quarter mile, and goes over 300 miles a week, So don't tell me NO one spends that much money on a car to drive every day. Just look at all the cars that cost 50, 000 plus on the street that people drive every day. If your theory correct , none of those people would drive them daily, because they cost so much, and the people would not want to put wear and tear on them. And some of these 9second cars today have cams smaller than mine. So there is nothing unstreetable about SOME of them.

Vipers are about 80,000 and some of them are daily drivers. And some of the 9 second cars these days have very mild motor combos with a blower or turbo and dont have near 80,000 in them. (And some of the people with cars that fast are not rich at all). Thats just the reason some of the folks with them drive them every day. Just like some people (like you it seems) would not drive them everyday because of the money involeved... Some people don't want to spend that much money on a car that is so streetable just to drive on the weekends a 1/4 mile at a time. It's kinda like a Viper. You have some people who only drive them on the weekends. (apparently you would fall in that category) And then you have people like myself that would not spend 80,000 on a car just to drive 2 days a week. It would be a daily driver, and why not . It's mild enough. Just like some of the 9 second cars are . A mild cam in a built motor with boost is very streetable. There are 12 second cars on here with more radical motors than some of the 9 and 10 second blowr and turbo cars.

Like I said, your post was FALSE ... Not opinion, and you DON'T think before you speak, or else you would not have posted most of what you did . What part did you not read about the person I know that has a 9 second daily driver a few miles from me, or the other people that have them. What is so unstreetagble about a motor like a 355 with a blower and a little bitty 218/ 230 cam. NOTHING. That motor is milder than many of the 12 second cars on this board with 305, 306 cams etc. Some people have money or the know how, and don't mind.

You have so much too correct, that I won't bother. Like I said, they are NOT everwhere , but they are there. Again some people have them as there only car. What part of that don't you understand?? There is nothing too be opinionated about. Some people have 9 second daily drivers. Some of them don't even run at the track all that much, so the are not purpose drag cars. But again . There is nothing to have an opinion about . They are out there . How do you have an opinion about that. You don't. It's false to say there are none.


If I tell you a zebra is black and white, and you think its green that is not your opinion. That is false. Learn the difference. I gave you facts . Not what i think. One lives down the street from me. Ther is NOTHING to debate. But some people will try to argue anything.






And as far as nitrous being cheating. I should have known you would have trouble comprehending things when I saw that idiotic statement.

 

Relax buddy I didn't mean to hurt your feelings LOL. I'm not even going to sink to your level but I will respond to prove my point. I will just say that you sir are pathetic, you're post was FALSE haha, and do not insult my intelligence either because I'm smarter than you. Also, I said it's not a DEBATE, it's a DISCUSSION. Do you know the difference, I mean you should if you graduated 4'th grade (honestly, I'm not trying to be a dick).

"First of all just by the first sentence in your post, I can see you don't read or listen. I said they are not on every corner, but they are there."

I said a significant amount, mean an amount big enough to be recognized. So you my friend are false on that statement. Oh and what does that second sentence mean, if you could please clarify. Once again your writing skills have shown weakness in that contradiction.

"I know that has a 9 second daily driver down the street from me, or the other people that have them. What is so unstreetagble about a 355 with a blowr and a little bitty 218/ 230 cam. NOTHING. "

You talk about it as if it is a common occurance, yet you get angered when I ask if there is a significant number of them? Yet another contradiction. Oh and please show me a 355 with a little bitty 218/230 cam that runs 9's or 10's PLEASE because I would like to model my combo after that. Regardless of what you seem to think of me, I do know a bit about cars (I have about 6x as many posts as you if you didn't notice), especially mine and I know that you are oversimplifying to make your point seem like it's glowing. To make a 355 with an "itty bitty" 218/230 go 10's you need crazy heads, and crazy boost... Now to get crazy boost reliable enough for the street is a whole other story, you get into blowers, cog pullies, custom IC's, massive amounts of fuel, etc. etc. Most importantly, as RSKrause said recently on this thread, a TH400 with a 4200 is not streetable. So basically you're idea is not feasible as it stands...

So I guess that means you are false right? Yup.

"You have so much too correct, that I won't bother."

I didn't even have to correct you, I just showed your contradictions and errors in your statements. Let's not let this get further than this because I'm sure that the people that actually want to discuss 355 vs. 383 don't appreciate this bickering.

Hopefully when and if my car gets to the 10 second level, it will be able to be driven on the street to get grocies or go pickup my girlfriend or whatever it may be, but you can bet that I won't be daily driving it even though it can be done. It's just not logical to me to daily drive it when I could take it out other times and enjoy it more and get more adrenaline rushes than I would driving in traffic or commuting on the freeway. If you disagree with my opinion then say so, but please don't tell my opinion is wrong, that's an oxymoron.
