Je vous met un lien sur un post trés complet de nos amis amerlocs sur sr20-forum.com
http://www.sr20-forum.com/all-motor/24290-sr20de-dyno-power-write-up.html

Vous avez chaque dyno en fonction de chaque modif .

en gros avec ligne(heeader catback mufler) , cai , AAC s3 JWT, Ecu JWT , flywheel il monte a 145cv contre 120 stock

Pk des valeurs basse alors que le sr20 fait 143 cv par chez nous ? tout simplement que c'est la puissance aux roues ! compter environ 15% de perte.

CAD que son moteur sort un poil moins de 170 chevaux pour 2500$ de prepa

Si j'ai loupé un truc hésitez pas a corriger je suis pas un pro de l'anglais !

J'attend vos réactions , et j'économise deja pour ma part

Edit si je me trompe pas le moter a 260 000 km
Edit2 la sentra SER fait 140cv stock .

Ok guys here is a thread that will anwser most of if not all of your questions on popular bolt-ons for the SR20DE motor. Please try not to cloud this thread up with you should of done this or that. i did all of these on purpose with this specific inteniton of sharing my findings. if you have questions please dont hesitate to ask pm me and ill post it in the thead
Mac

First off this is a 1991 Sentra SER with roughly 169XXX miles. AC is still in and will be removed at a later date.

Modifacations in the thread include:
Aem Cold air intake
Ebay 2.5" header
Obx test pipe
Jim Wolf Technology S3 cams
JWT ecu tune
HKS Sport Exhaust
9lbs. Flywheel


Base line power

the 119 and 120hp pulls where in 4th
the 102 was in 4th with the ac on. i aways wondered what the Hp drop was with the ac on. now i know.



INTAKE
Here is the dyno with the AEM Cai installed. i used the my 119whp run as an overlay cause it doesnt have the dip the 120whp does and is more realisticly the accurate pull.

Most of you will laugh at the fact that i made almost 4whp over stock. but as you can see there is more to the gains then peak HP. and im sure that a few of you know that power band is more important then peak hp.

You can see in the graph that from 3300rpm to 5000rpms i am making more HP then on the stock pull. but from 5k rpms to 5.7k rpms i am making the same as stock. from 5.7k rpms to redline i am making much more then i was stock. in some parts around10-12whp more. also my peak hp is moved to almost 6.5krpms. about 300rpm later then stock. torque is almost not changed at all. this is a good thing and a bad thing but does not effect the feel of the car at all.


the over all feel of the car now is very smooth in the top end and feels much better. i can feel the car pull more but i am very aware that there is some mental aspect to that.

Exhaust

Here is the dyno with the hks exhaust and i must say i am very impressed with the findings. much better then i expected. in this its my base, Intake Installed, and intake and exhaust installed you can see the top end gained a very good amount of power as much as 20whp over stock. cant wait to get headers and see the gains. the exhaust is to quiet so im going to be installing a test pipe. well see if any gains are produced





JWT S3 CAMS, JWT ECU, AND TEST PIPE
Installed the JWT S3 cams and test pipe. i was very inpressed with the gains. the torque is unbeliveable. the intake exhaust run is the last dyno i had.Now the cam run is very impressive with the amount of torque it is making. you can also see that the line is much smoother then the blue run. this is due to a new cap , rotor and wires. the parts are not new but they are nissan where my car had cheap aftermarket set on them, so they are new to the car. the s3 cams with JWT ECU run is not bad at all raising the HP and TQ all through the power band. well some would take that flash as a waste of money but the car did make more power and idles much smoother now then it did with out it. the drivablity is also better with it.





HEADER
heres the dyno with a ebay header and a 2.5" outlet. The Blue Run is the header installed and the Red Run is the last run i did see above for more info on that run. the headers were a great complement to the whole setup i have going right now. you can see that every part of the rpm range has a gain, not one spot does not. the peak is only 7whp which is more then i was expecting. this doesnt exactly mean if you put just a header on it will provide this kind of HP i think with the cams intake ect they are a good compliment for it all.





FLYWHEEL

dyno with the flywheel only made 2whp and 2wtq at peak but like all the other mods its is through out the power band. the engine revs much smoother and faster. rev match is like breathing its super easy.





i installed my factory cat and looks like i lost alot of power through out. sucks but now i dont have any buzz in the exhaust anymore.

une petite liste de pièces avec tarifs chez JWT

Here is a list of what we can do for the 1991+ Nissan Sentra SE-R/200SX/NX2000/G20/Primera/Sunny/Pulsar using the SR20DE engine.

Note: Go to our web site and enter the part # in our products section to get more information.

ECU upgrade $595.00 on an exchange basis. We remove the top speed limiter, raise the rev limiter to 7,700 rpm and put in the most aggressive fuel map and timing curve for 91+ premium fuel. We also optimize the throttle response code for better throttle response. Call for current turnaround time. (1990-97 at this time only) We do have turbo programming along with different injector/MAF combinations available. We can reprogram your ECU for use with the SR20DE-T Bluebird and Pulsar engines. Call us for details on this. We do offer an ECU core exchange option. The additional refundable core deposit is $500.00 for the 1991-94 models and $700.00 for the 1995-97 models. Call us for more details. ECU upgrades for the 98+ models are still in development. Check back with us later to see how our development is progressing. It is possible to use a 1995-97 style ECU into the 98-2001 models. Contact us for info.

PSER1-1221X Pop-Charger air intake system $159.00 (1991-99)
PBREA-THER0 AIV Breather filter (for 1991-93 models,) $13.00

PSER0-1XC61 Pop-Charger air intake system $159.00 (2000-2002)

ECU and Pop-Charger net about a 15 HP gain together

JWT NOS system (1991-97 only) is a microprocessor controlled system (50 or 100 HP gain,) that works with the JWT ECU (you must have a JWT ECU upgrade to use this.) The NOS Control Module actually switches the programs in the ECU between the regular upgrade and the NOS program. NOS is only sprayed during the following conditions: Above ~ 2200 RPM and shuts off ~ 200-300 RPM below the rev limiter, works only on full throttle depression, and with the arming switch on and bottle open. The air/fuel ratio stays at the best optimum settings under all conditions making this system the safest and most advanced NOS system available.

carement couple Fidanza + Embrayage stage 1 livré = 600€ ...

Pour info sur les flywheel

Pour fidanza il existe 2 modèles donc le 108 et 109 dents :

143201 = 109 tooth
143621 = 108 tooth

108 densts = sr20de

et 109 dents pour voiture avec OBDII et pas de crank sensor

[TITAN-X [grade suprême]matmax]

tres interessant !

[[Suprem NX-POWER]raph]

donc une 1.6l 102ch fait 80 et quelques chevaux au roues , quelle m...
et le 2L ne fait "que" 120ch
cela dit tres interressant
apres je pense que ça s applique au sr20 quelque soit le matos ( ex : une ligne qu elle soit ssauto ou autre , mise a part la qualité du matos , c est kif kif ) non ?


ps : y en avait un sur un autre forum de nissan( ) qui avait passé sa nx au banc et il delivrais 116ch si je me souviens bien !
donc il deboitais presque autant qu une 2L ?!

[[Suprem NX-POWER+]antoinezgz]

Oui, Jul a sa petite 1.0006l un peu prepa, et elle a l'air de marcher pas mal du tout...

[[Suprem NX-POWER+]crousti]

les 116 cv de jul n etait pas au roue , mais au moteur

15% de pertes sa parait beaucoup (pour certain) mais c est ceux que je met quand je fait les test dynolicious et malgres tous c est pas optimiste
17 % pour l Tchou-Tchou qui est equiper d un torsen
20 % pour les traction
25% voir + pour les 4 RM

bon bien sur c est du a peu près car par exemple je pense que d une nx 2.0l a une 1.6 l il y a une difference de part la taille des roue , leur poid idem pour les cardan ect

[[NX-POWER]Julien]

Edit2 la sentra SER fait 140cv stock .

Aux US ou en Europe ?
Parce qu'aux USA, ils mesure la puissance des auto selon la norme SAE (qui doit vouloir dire "society of american engenieers" ou un truc du genre) alors que chez nous on par le chevaux DIN (Deutsches Institut für Normun).
La norme SAE mesure la puissance brute du moteur (sans les accessoires, genre alternateur...) alors que la puissance DIN tient compte des accessoires, est est donc plus proche de la realité.

[[Suprem NX-POWER+]toto491]

Alors la julien tu m'en demande bcp ! je ne saurais te dire pour cette différence DIN/SAE faut se renseigner !

Après pour le pourcentage de perte , c’est variable effectivement , ca reste flou , normalement au passage au banc il laisse la voiture redescendre tranquillement pour calculer ses pertes .

donc en faite meme entre deux nx 2L, il peut y avoir une difference de pourcentage ?

très faible mais oui

[[Suprem NX-POWER+]toto491]

on pourrait presque pousser le truc en disant que tu perds plus avec une huile de boite crade et épaisse par exemple enfin bon pour 0.1% on va pas se prendre la tète .

tu pousse le bouchon un peu loin morice
non mais comme les roulements , ou rien que l entretien du vehicule ...

bah c'est sur qu'il y auras forcement un difference entre 2 NX pas identique !!
meme deja entre 2 nx stock , il peut y avoir une difference !!

[[NX-POWER]Denrée]

En gros, il me manque:

l'ECU JWT (je me suis déjà renseigné auparavant, c'est pas super cher), environ 300$ sur ebay
un volant moteur alléger

Et après, j'ai au moins la même puissant que le mec, au moins car j'ai les aac JWT S4 moi.

[[Suprem NX-POWER+]toto491]

moi je commande tout ca dans l'année VMA+embrayage prévu pour cet été et Abre a cam et gestion l'hiver prochain !

[[Suprem NX-POWER]raph]

ça vas envoyer du gros , je vois
