hey firedog not trying to thread jack or anything but i like your seats man nice choice in the color and design

 

the juice is only dangerous if you dont run enough fuel to go with nitrous.

 

finally some ones that knows a lil something if you look at my air fuel ratio is perfect stright all 11 and some all the way

 

it's all good man thanx....

so from what ive gathered the kit i posted, with a proper dyno and tune, wideband (just in case), i shouldnt have any problems at all ...and hopefully with I/H(s-pipe)/ pulleys/E my numbers should be at around 250 whp for $3,000 dollars...i like

 

yeah that sounds about right im at 200 and im all stock like i said later on ama get headers maybe ill have around 215 or so and ill do some other thing to get more hp im fine with my torque but ama work on my hp now

 

250hp nitrous is more abusive then 250hp f/i. f/i is a constant, or gradual build of power whereas nitrous is an instantanious "hit" of power primarily on whichever piston is at tdc at the time of hitting the button. Its like downshifting. Im not saying its going to be problematic im just saying nitrous for the same hp is a slight bit more abusive. Picture towing a trailer, now picture ramming it. Thats why the v8 guys liek it so much, having 8 pistons to distribute that initial hit. 100shot on a 4 cyl is 25 hp slammed into each piston versus 100shot on a v8 its only 12hp against each piston.

 

well im going for a 75 shot ......and im looking into some sort of gradual increaser type thing i heard about (if i ever decide to go above a 75 shot)

 

http://www.zeropointindustries.net/s...roducts_id=247 ok what about this guys?

 

the best thing you could do is go f/i and get water injection. it works the same as nitrous, but instead it cleans your cyilinders, and reduces knocks!

 

i think you should build the bottom end of the engine and shoot a 150 shot and damn you'll be fast.
iono what i would do without nitrous man, if you ever do get it you'll know what im talking about that kick that is gives feels better than anything, it raises adrenaline so fast lol.

 

501scionxb: if i get those high comp pistons will i have any engine problems when im not spraying ?....wierd idle?, sucky gas mileage?...etc.....or are thay just really strong pistons that are made to take a beating?

 

high compression builds more power, but requires higher octane fuel. 11.5 - 1 may be too much for n02 on pump gas it would need a perfect emanage tune and hope you never get stuck in traffic on a hot day or it will knock.

 

what exactly happens when an engine knocks?.....

 

you answer the door....ROFL that was so lame but i dont care hahah

 

you need to learn how an engine works.....
(knock,detonation, pinging all pretty much the same btw)

the compression ratio is how much the air fuee mixture is compressed. As you compress it, it builds heat, too much heat and it detonates from its own compression before the spark plug ignites it, more importantly before the piston is all the way up, in turn trying to rotate the engine backwards.
Its what limits how much nitrous, boost etc you can run. Higher octane gas has an additive in it (the octane rating) that makes it less prone to ignition and makes it burn slower. Meaning more compression, boost w/e before knock accures. The more you can compress the air fule mixture the more power you can get, a bigger more explosive bang, but you have to walk the fine line. Too much cylinder pressure from boost nitrous etc and it will knock. You need some form of ignition control to retard the timing as well to help prevent knock regardless. Changing to a colder heat range plug works in a small degree as im sure youve seen all the f/i guys do it. The colder plug doesnt hold as much heat and also helps a small amount against knocking.

this is just a brief quick overview to get you started.
You need to decide how much nitrous you want to run and what fuel and etc etc. there are alot of variables. Most street cars on 91 octane n/a cannot tolerate 11+ compression ratio without taking out alot of timing and putting you back near stock hp levels because of it. Nitrous increases the cylinder pressure too so it will induce knock in when used in large amounts (150hp) zpi will be able to answer your question better. Hope this puts you in the right direction.

 

...? where did this come from?

 

ohhh...okay i wasnt familiar with the term knocking...i understand mostly how an engine works, how to compensate and what not is a diffrent story..thank you, you cleared somethings up...

i think as of now i will be going with a 75 shot and 93 octane (to be safe)....

in the future i would like to get the tc to 300whp(will satisfy me with this car doesnt need any more in the engine department) going the nitrous route....any suggestions on how to achieve this safely and without consequences like strange idle and 4 MPG ,

 

ps this is my DD car

 

well the tc is my DD car too and all i do is use v power gas which i think is 93 octane and thats it and jus change your spark plugs regulary and you'll be fine man iono why your worrying too much about this jus buy the kit and install it youll be good to go, if you doubt it too much your never gonna get it. the jus my opinion and thats what i did cause most ppl here are scared of nitrous and think it blows stuff up but thats jus bad rep if you know what your doing and your not running lean your perfect to spray as much as you want. jus like me :-)

 

not scared just want to be informed, im going to do this just want to do it right....got to get my I/H/E setup first though so i still gotta about 2 months research on this
theres many turbo charged peeps at 300hp, some supercharged peeps at 300hp, i plan to be the first nitrous peep at 300hp..
