Although you can make small gains with i/h/e, it mostly shifts power to different rpms depending on the set-up. With this car, I'd say the aftermarket intakes, and aftermarket y-pipes can be worse than stock. If you change the design around a bit for better/smoother flow, you can gain a bit more performance.

With the mods you have now, MREV2 with spacer will not get you 8-14hp.

 

ive seen it with my own eyes on a 06 g35 with stillens pop charger z tube and stillen true duals on a superflow dyno! do my eyes lie?? and the exact gain was 12.7 hp at 4600rpm and a peak gain of 7.9whp at 6400!!

 

Same day? Same time? Same weather? Same location? LOL dyno chart please.

 

dyno run before install was around 8am it was 45deg. however i did not see the base dyno run i had just missed it. right after they put the mrev2 and blox plenum spacer along with motordynes isothermal gaskets and coolant diverter valve and isothermal throttlebody spacer. then he drove the car hard all day until about 4pm car sat about 1 hour before dynoed again temp was 52deg. i havent seen him in a while but as soon as i see him ill get the dyno sheets. i will tell you this i have dynoed my 05stock and modded on both dynojet and superflow dynoes i find dynojet can fluctuate where superflow is very close. i did 5 pulls on each both stock and modded. superflow started out low at 242 then by pull 3 was up 248 and both pulls after where within 1 to 2 hp dynoed with 10min cool downs between pulls. same on dynojet but hp started at 231 the sencond was 247 third 239 fourth 242fifth 249 so i did trust those dyno #'s. dynoes where done stock on the same day temp 70deg. also trq on dynojet didnt even seem right at 235, superflow shown 228 steady. so when i modded i/e i dynoed 16 hp more on superflow on a 80deg day and dynojet gave me a max of 19hp. so i chose the lower number as its probly more accurate

 

Is the power curve the same?

And like I said, there is no way you gained 14hp with MREV2 and spacer. Hell, the thing won't even get you 8hp... maybe if you were boosted...

 

My Big Papi bobblehead gives me 19 peak hp, just from the smile alone. Always feels like a troller when it's 50 posts or less...

 

if you send your ecu out then you gone need a back up car thats too much of a hassle,,.how long does it usually take if anybody knows?

 

Then get the Osiris. Not much downtime involved... just gotta load the programming.

 

what is osiris???

 

If what you posted is true why did you make all the mods you have listed?
Three years ago at least two of the import mags were squeezing HP from
our cars not to mention my favorite Nissan Sport. Every one found that
exhaust and the MD spacer created quite a substantial amount of RWHP. That
information alone was enough to arouse my interest in all the mods you have
listed as worthless!

IMO, it's the best reflash currently available for our cars. Lots of info here about it, just do a search.

^thanks for the link

 

Just FYI...You know Tadashi at Technosquare sells all the ECU codes to tuning companies in North America as well as Japan...Osiris most likely got the info for their software from him. He is the only guy capable of cracking the ECU's in North America...which is why Nissan of North America sends him all the new vehicles to crack the ECU's.

 

"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."

the 350z had more hp from the factory then listed and it had the same displacement. so there are items that can be added to increase the hp output on the 287-290 hp engines.

 

well the only mod i've done performance wise is a HFC and a crawford and maybe the y-pipe. as far as the intake it just sounds more agressive. I'm sure with all this i'm prolly not making 300hp to the crank. and i said u can't squeeze "much more" meaning i m sure u can get a couple more hps out but ur not gonna get noticeable diff unless u go FI.
