Car Tuning 101

Actually, AFM in this context would mean Air Flow Meter, which is basically the prehistoric version of a MAF and uses flapping doors in the intake to indirectly measure the amount of air passing through (which sucks for many reasons you can imagine)
 
A little bit off-subject.... what would you guys think would be the best material to make an airbox out off? Something that would keep heat away yet but cheap and easy to work with... I can't keep the stock one because there is no space to use the stock one.

fiberglass probably would be th ebest option for you , light , easy to shape and doesnt conduct heat that well
 
AFM sux *td* *td* *td* avoid these injection system poor upgrade possibilities
mostly seen on toyota and mazda and some early ford
MAP is the best

can we made this thread a sticky :dunno:
maybe also paint 101 :dunno:

in most cases, MAF systems can't be upgraded much because the intake tubing cant be bigger than the sensor, wich is part of it.......the "flapping door" was called VAF (van (or vanne) air flow) and was used on old Ford escorts
 
Vaf were on volks if i can remember correctly ... Anyway those system are really obsolete now
I updated my first message with new books , also don't worry this thread will soon be sticky as paint 101 *tu*
 
To supernaut and 200sxboy or anyone else in the know.. good engine books have been more than already covered but what about suspension chassis books? I need to choose the spring rate and length for my car and I'd like to get as much info as possible before making the fianl choice. Plus I' mpretty much changing the whole rear suspension geometry and all... wondering what the effects will be, I also need a few stenghtnening at a few palces, etc... I need more knowledge! :laugh:
 
if your rich , Supernaut recommended me Race car vehicle dynamics http://www.amazon.com/exec/obidos/A...3/sr=2-1/ref=pd_bbs_b_2_1/102-7480072-0229742
that's a 100$ books and it's a pretty big thing to read (~900 pages)
Perhaps you could find some valuable info in Tune to win by Carroll Smith's
http://www.amazon.com/exec/obidos/A...4/sr=2-1/ref=pd_bbs_b_2_1/102-7480072-0229742
I ordered that books ,it's shipped to my parents house but i haven't started reading it , but with amazon in the table of contents it speaks about suspention geometry and those things , and it's just 20$ :bigup:
 
un char turbo, le intercooler faut le mettre avant le throttle parce que un turbo c chaud...

mais pour un supercharger, ques qui est mieux?

mettre l'intercooler avant le supercharger, ou apres (soit avant le throttle)??

Ma philosophie est la suivante, si ma philo est pas bonne, ben corriger moi svp

L'aire froid est plus dense, donc plus d'air...

Si je compresse plus d'air

Sa va dir que je vais avoir encore plus d'air qui va se rendre au throttle....

corriger moi SVP

merci!

non ca marche pas de meme un turbo c le cote compresseur du turbo qui rechauffe l'air alors ca donne air filter,turbo,intercooler,throttle body

pour un supercharge j'imagine que la "pompe" (supercharger) est chaude par la friction des engrenage fak si tu y met un intercooler , le supercharge vas etre a la place du turbo.

mais la plupart du temps les supercharge stock no intercooled le supercharge est apres le throttle ca doit etre moin chere de meme j'imagine.

kk, thx...

Ouin, cobalt SS le supercharger est direct sur le throttle...

Bonne explication, mais juste le fait de comprimer un gaz (dans ce cas-ci l'air) augmente sa température.

Donc même si le compresseur serait "froid", la température de l'air qui sortira sera plus élevée.

sa sa complete tres ben la réponse de mustangup

thx again!

Je crois aussi que c'est bien du catalyseur jusqu'à la fin, d'où le nom "Catback"

sa le dit bien Catback

Cat= Catalyseur

back= du catalyseur a l'arriere du vehicule.
 
bore and stroke/alesage et course

pour les configuration moteur ya trois possibilite je vais essayer d'etre claire

1: sous-carre = stroke > bore = low end torque
2: carre = stroke = bore = overall
2: super-carre = stroke < bore = hirev hp
