are buses turbo or supercharged?turbo2nr 12-10-2002, 04:10 PM well i no buses arn't natural aspired they have 2 be turbo or supercharged to pull all of those people and its own heavy weight come on now! plus when im in da bus in da back near the engine i hear a spoolin sound then when the throttle is let of i hear the PPPHHIISSSHHH! so i figure it has 2 be ither turbo or supercharged... but i think its supercharged cause a turbo needs ceritan rpms to spool n a bus shifts after 3000 rpms. so i m ifiguring that it is probably supercharger cause superchargers work from idle to abut 4000 rpms!... buy i could be wrong :eek: :eek: so if sum 1 can clear it up if a bus is turbo or supercharged it would help, and i would win $10 from by boy cause i would be rite!! so plz help me win dat $10 ............ ......so i can buy sum stickers 4 my honda:D j/k tanks 1 J SPEC SilEighty 12-10-2002, 06:47 PM Turbo's dont just rely on what RPM your at. The reason why you probably think that is because on smaller engines like honda b16a's or nissan sr20det's they are small in displacement so the higher you rev, the more exhaust gas your going to get spooling the turbo. I'm not sure how many liters a bus engine is but I would guess 8 liters or more. For example, there is this guy near me who has a turbocharged mustang using a T3/T04E 60 trim. His mustang is 5 liters which is way bigger than the small smort compact engines we are used to. He is running only about 10 psi but had full boost by about 2400 RPM. Another friend of mine uses this same turbo on his Honda B16A and he is running about 10 psi also. He doesn't have full boost until about 4000 RPM when it is flowing more exhaust. So a bus could easily be turbocharged, and many are. So the bus that your riding on is most likely turbocharged. I think you owe your friend $10 :D TatII 12-10-2002, 11:44 PM well most diesels need to be turbo charged. thats why you see alot of trucks that says turbo diesel on it. the only diesels that aren't turboed are the gasoline engines that are converted to diesel engine. the way diesel engine works is that they dont' even need a spark to combust the air/fuel mixture. the reason who a diesel can do that is because they have a compression ratio that is around 10 X's higher then a gasoline engine. so instead of having a 10:1 compression, they would have a 100:1 compression. since the air molecules are compressed tighter together, the friction of the air molecules will heat up enough to ignite. now since it has soo much more combustion, you need a turbo to force more air into the combustion to support such a high compression ration. and thats how a diesel engine works in a nutshell. turbo2nr 12-11-2002, 09:27 AM kol.... good job... i kenw it waz turbo , im going 2 get my $10:D tanks luti 12-11-2002, 09:36 AM sr20det2nr: can I ask you a question? How much extra time and energy does it take to type like that? Using numbers for words and using poor slang and basd misspellings obviously done for a reason. I'm sorry it just makes you look dumb, it's hard to take someone seriously if they write like they are trying to be something else. turbo2nr 12-11-2002, 09:44 AM well im sorry if you dont take me seriously if I dont type in proper english...... for god sackes its just a forum its not english class..... you dont have to be literlary correct all the time as long as you get your point across thats all that counts and plus i dont have time to sit down and type out every word .. see this response took me longer cause i typed it in proper english. TatII 12-11-2002, 12:53 PM don't worry sr20det2nr i'm use to it and luti that whole typing improper english thing is a Queens thing. i know alot of friends who types like that it they can type like that much faster by using abreviations. such as "n8" for "nate" and "u" for "you" and such. when you see them type, they type just as fast as us. so its really nothing J SPEC SilEighty 12-11-2002, 01:24 PM Originally posted by sr20det2nr i kenw it waz turbo , im going 2 get my $10:D ummm.... did you forget what you wrote?

No offense but I wouldn't be talking. Not all hondas are "rice rockets" like you say. My friend recently dynoed his civic SI and it put down 500 HP and 333 lb-ft of torque at the wheels. Previously he had 370hp and 276 lb-ft of torque at the wheels and ran 11.92 in the 1/4. He should be in the low 11's or high 10's now. http://hrracing.com/RoTM/Nov_2002/boostfed_dyno.jpg video of his 1/4 run (http://hrracing.com/RoTM/Nov_2002/boostfed_11secpass_02.avi) Oh, and did I mention that he drives this car to work EVERYDAY. Not all hondas are terrible like you seem to think. turbo2nr 12-11-2002, 01:58 PM i no , i no i respect those fast hondas i used to want a civic:eek: but i seen the nissian way.. but yea i respect and like hondas that run great and look good. but this guy had like intake and exaust i think, but yea some hondas are kol! J SPEC SilEighty 12-11-2002, 02:04 PM Ok, it's cool :cool: but yeah, the fast hondas are few and far between. most of them that I see are like you described with an intake and exhaust, or in other words, pathetic :rolleyes: turbo2nr 12-11-2002, 02:09 PM they are soo damm ricy with the intake n exaust dropped with hub caps and they think that they are fast! it gets me mad that when i get a 240 i got 2 was gas on people like dat!:mad: TatII 12-12-2002, 08:22 PM well you might have heard of this from before, but our 240sx aren't that fast of a car either. in only looks fast on paper. with its 155hp and 160ft lb of torque, and RWD weighting at 2800 *S14* and guess what? our 0-60 is only 8 flat and our 1/4 mile is in 16.1 seconds. hmmmmmmm not exactly what i would call fast. of course our cars responds to mods alot better but that just makes our cars quick for import standards. and its really more of a driver thing cuase i can beat a LS with I/H/E that has beaten Si's, GS-R's, 1.8T's, and even a SE-R spec V. lets say i himulated him by atleast 3 cars on 3 runs straight. but~ no offense Ivan but you can't drive. hahaha anyways when i race another 2 friend of mine, who also drives a LS with I/H/E but his weights more cusae he got a 4 door. he can beat me by 2 cars!! and another friend of mine with a 7th gen Accord coupe with I/H/E who can beat me by a car! its mostly in the driver. assuming that we all are equally skilled which me and my other 2 friends are, their hondas are faster then my 240. even if you look at stock numbers. a stock LS integra can dash from 0-70 in 7.6 seconds and can run the 1/4 mile in 15.9 seconds. not bad for a non v-tec eh? don't underestimate those cars. SR20DETpower 12-12-2002, 09:02 PM buses or turbocharged......... I dunno of any superchagrded deisel applications....... turbo2nr 12-13-2002, 09:18 AM see i never really underestmated those cars. my cousin has a honda civic 95 with a d16z vtec sohc and i no that those cars run! we beat alot of v-tec powered civics, and also many other 4-banngers. as for the 240sx thing, i know that it isnt the fastest car in the world, in stock form its alright its not anything special..but as soon as i get my 240sx the next week im droppin in the sr20det motor, i already got 1,500 saved up an i should get my 240 by next summer so by then i should be up to 4,000 so i will get da sr20det, and again this is not another pipe dream! this is reality!:eek: J SPEC SilEighty 12-13-2002, 01:42 PM how are you going to be able to afford a 240 and an sr with 4 grand? the complete sr swap alone is going to cost you about 4 grand if not more turbo2nr 12-13-2002, 02:09 PM PARENT = CAR:D my parents are going 2 buy me a car 4 collage so im gona get a 240! natedogs911 12-18-2002, 03:36 AM Originally posted by TatII well most diesels need to be turbo charged. thats why you see alot of trucks that says turbo diesel on it. the only diesels that aren't turboed are the gasoline engines that are converted to diesel engine. the way diesel engine works is that they dont' even need a spark to combust the air/fuel mixture. the reason who a diesel can do that is because they have a compression ratio that is around 10 X's higher then a gasoline engine. so instead of having a 10:1 compression, they would have a 100:1 compression. since the air molecules are compressed tighter together, the friction of the air molecules will heat up enough to ignite. now since it has soo much more combustion, you need a turbo to force more air into the combustion to support such a high compression ration. and thats how a diesel engine works in a nutshell. with a 100:1 compression ratio it would bend the rod 20:1 is more like it some as high as 24:1. and there are plenty of N/A diesels that are not converted Suislide 12-26-2002, 11:01 PM Originally posted by sr20det2nr PARENT = CAR:D my parents are going 2 buy me a car 4 collage so im gona get a 240! well there's your answer right there. mommy and daddy are buying his car for him.:rolleyes: J SPEC SilEighty 12-27-2002, 12:48 AM yeah even after his parents buy him the car, 4 grand isn't really going to be enough to get the swap done... think about it this way...

So it's going to cost you about 5 thousand at least to get the swap complete. turbo2nr 12-27-2002, 09:30 AM ummm...no i getting the whole front clip for 2,800 shipped to the shop, i dont need a intercooler cause the stock one is fine 4 now, also a bov i dont need rite now, fuel pump isnt need rite now either, cause im not going 2 be running it hard, im leaving it stock 4 bout 6 months untill i can save sum money and do my intake, exaust, intercooler,bov, boost comtroller, fuel mangament sys, fuel pump, then brakes , and suspension, about the computer i have a friend that works at nissian that can reprogram the whole computer 4 me and raise the limiters up some, so i figure i can get the swap done for 4g's turbo2nr 12-27-2002, 09:31 AM forgot 2 say thanks 4 ur help j-spec sil-eighty im not trying 2 dog on u or nuthin i'm just tellin u how i see it! ~1~ J SPEC SilEighty 12-27-2002, 06:47 PM Originally posted by sr20det2nr i dont need a intercooler cause the stock one is fine 4 now better hope it comes with one because sometimes even the front clips are missing it. Originally posted by sr20det2nr also a bov i dont need rite now Have fun dealing with the shock of the reverse-direction air when you let off the gas Originally posted by sr20det2nr fuel pump isnt need rite now either doesnt matter if your going to be running it hard or not. what year car would this be going into? If its an S13 I would recommend changing it becuase the stock pump is most likely going to be worn out and tired and isn't going to be able to deliver all the fuel you need.

It all depends. vBulletin®, Copyright ©2009, Jelsoft Enterprises Ltd.
