hey guys i am gonna dyno my car tomorrow morning and dnt know what to expect. i have dynoed my car before but it was at japtrix while they were tuning it with a utec but i sold the utec and dnt know what to expect. with the utec i dynoed 294whp on a 05 non revup. now im without the tune and want to know what you guys think.

Mods
1. AFE intake
2. SSV MANIFOLD
3. Xerd Long tube headers 2.5inch outlet
4. Borla true dual with custom 2.5in piping until my 2.5 in magnaflow x-pipe
5. throttle body bypass

Here are my dyno results with a borla exhaust now the shockwave dyno is next week

 

How come you ditched the UTEC? Going with something else?

Either way it will definitely be less without a tune, but any guess will just be that, a guess.

 

i am dynoing the car because i wanna do a before and after with my borla exhaust then with my shockwave sinle ti tip exhaust

 

yea im gonna go with osiris from uprev. i hear nothing but great things from them and i didnt like the fact when i would be driving i would feel my car hesitate when the tune kicked in. it was a very bad feel so i sold the utec and will be going with osiris

 

Nice.

 

Lol thanks

 

Osiris is a great product. Had my car tuned with osiris. If you have a 05 and up you can purchase cipher and display live parameters (a/f ratio, air intake temp, coolant temp etc etc). With your mods you def want a tune because your car might be running rich. I have popcharger, plenum spacer, test pipes, injen ti td exhaust + magnaflow x pipe and my a/f ratio was WHACK. Even if you dont make much power you will have the peace of mind that your car is running safe.

 

Thanks for the info bro. Yea i know i will defintly be needing all tune and i just love what i'm hearing about osiris. my utec was great but it jus had that hesitation that i didnt like. the numbers were great. 294whp on a heartbreaker dyno is no joke especially on a n/a 350z.

 

o yea and my car is defintly running rich i can just smell the fuel lol

 

Let me know what you guys think

 

bump

 

not to call you out, but you made 26? on a dynojet without utec and made 294 (on what a dyno dynamics? Mustang Dyno?). I can't see you gaining roughly 50whp with just a tune. Sorry if I am reading this wrong, but I just thought I'd ask.

 

yea i know it seems low compared to what i made before but its true! when i dynoed with the tune i had a plenum spacer and mrev2 so i dnt know if the ssv is hindering performance or not! jack himself at japtrix told me it waz 1 of the highest dynoes hed seen on a n/a z. as you can see my car is runnin at a high a/f ratio its about 13.2! wen i got tuned it was at 11.9! it waz also in december which it waz a cold day! there are all little affects that could cause the dynoes 2 b so far off but it can happen! one things forsure my car pulled so much harder uptop then it does now!

 

Japtrix has mustang dyno now. I have no idea if they had diff type of dyno.


Edit: chefj

 

sorry bro not believing it............11.9 is pig rich on an NA car. 294 would put you 10+ more than ACEMAN (who dynoed on a dynojet) and had more mods. Sounds like the dyno was either defective or insanely over corrected. 13.2 is actually more reasonable then 11.9 and will make more power (on most NA cars). Unless this dyno was a dynapack (which tend to read higher than dynojets) I can't see it.

 

Yeah those numbers seem way too high for a DE engine. You are creeping on 300whp with only a few boltons...300whp was a holy grail NA number for bolt on Z's with the DE engine. It took almost a full engine build to get that high. Your dyno sounds very high.

 

Well then I guess there waz sumthing wrong wit the dyno that it read so high on my car! Why would my tuner put my car at 11.9 then

 

Thats a question for him, but 11.9 is very rich.
