Hey I Got Hks Full Exhaust, Cold Air Intake, Skunk2 Engine Spacer, Megan Headers. I Was Wondering If These Are Ok Mods To Get Some More Hp, And Does Any One Have Any Input On Wat Else I Will Need To Do After These Mods Are In. Do I Have To Get A Tune Up Or Dyno ? Please Need Help On This Guys. This If For My G35 Coupe 2004 Techtonic Trany .

If Any One Got Any Info Please Pm Me Or Just Post Thanx Guy.

 

HKS exhaust =, 0... intake = 0, spacers = 11-14hp, headers = 0 (unless u tune)

 

so i wont gain from the exhaust? so no dyno needed? just tune ?

 

 

so no help lol ?

 

add test pipes or HFC and then have it tuned with osiris

 

Will the the intake really add 0? I am going to get a spacer then get a reflash but just wondering

 

Once you get a tune you will get the most out of the mods you have...

 

thanx. so no dyno ? well the megan headers come with the test pipes.

 

No need for a dyno

 

the mods i got for "POWER" are FI high flow cats, meagan Y pipe, Crawford plenum (or spacers). U get nothing from a exhaust other than noise. im sure ur making 1hp to the crank or so.. but it's not noticeable. Intake is pure cosmetic/noise. I've actually seen dynos where the owner LOST a hp or two lol. a tune is crucial of course but thats only once u get all the bolts ons u want then get a tune to get them to all work together. Now if u REALLY want power.. the only power that will kick u in the ***** is going FI (turbo/sc) everything else ur just messing around. nissan(infiniti) squeezed out 287-290 hp out of a 3.5 v6 can't really get much more out of it unless u put it on roids.

 

Your mods will work better for you if you get your ECU reflashed. Check out Technosquare...those guys are awesome!!

 

 

OP, a dyno is not going to get you any power....it just shows you how much power you are putting to the ground.

I would ditch the headers if I were you. They are a PITA to install and if they crack then you have to take them off and put them on again. Put the mods on then get Osiris from UPREV or send your ECU to technosquare for a reflash.

 

ok these guys on here must be crazy. i have had my 05 coupe base line dynoed and then dynoed with stillen exhaust and pop charger. base line 248 and with mods 264 if thats not a gain then i dont no what is. oh yea those are whp numbers. i put much more on since then im getting it dynoed soon. you should gain to the wheels roughly for headers 5 to 7, hfc 8 to 10, cat back 7 to 9, intake 1to2, plenum spacer 3 to 5, mrev 2 with plenum spacer 8 to 14, and tune will depend on whats been done to the car. i have seen most of these parts being dynoed on my friend 06 coupe. however the best mod garrentied hands down is the mrev2 w/ plenum spacer. thats where his biggest gain was so far. i also ran into another member on here at a meet that has greddy e-management and he had it tuned with a gain of 42whp. on stock exhaust, hope this helped you
