Just got back from my car getting tuned came out with 255whp from 243whp last year stock plus bassani td exhaust this year I have 5/16 spacer art pipes and uprev I feel like I should have gained more than 12whp but I am on 275s rather then 245s this tine around.

What are you guys thought does this seem right or not

Forgot to mention I tuned it first and it made 250whp

 

i'd say you were lucky to even gain that much power with just an exhaust and spacer.

 

I feel like there should be a bigger gain based on what others here are making with the same mods on a de though.. art pipes and spacer 10whp intake 0 for the heck of it should be able to pull more than 2whp from the tune.

The timing is untouched though he put 2 degress of tim8ng and it went up few whp but he said its not worth it and it started to get choppy on the datalog so...

 

Welcome to reality

 

So then the motordyne parts make faulty hp claims or what are you trying to say

 

IMO from what I read in all the n/a threads these cars just don't benefit much of anything from bolt-ons. From your mods you might have spent around $2k for what 12whp? That's almost half way to FI kit. If this is the route you want to take then its all good, but I think that people on here really kid themselves wanting actual hp from bolt-ons with this car. This is my opinion and people might not like it but its true.

 

First of all,a spacer is just a wedge of metal.A generic brand would have given you the same results.Also,HFC's --a non-brand ditto.I take it you have
some sort of aftermarket intake?
Those are the numbers.Of course,they may vary by type of dyno and tuner.
The,"10hp increase+another 12hp increase " does not work that way in reality.
Major thing,how does your car feel?
Does it FEEL any faster?
Sometimes thinking that it does is all that matters...

 

Precisely why my first mod was a turbo. Sorry, op.

 

Car pulls harder than last year absolutely but from my tune that was 250whp to the 255whp my tuner pulled, no

Have an injen cold air that goes in my bumper but if I can fibd my stock air box im gonna switch back 8m thinking heat soak is part of my problem

 

I would if I could but theres no tuning availability for boosted 350z here only ones around here don't even know what in there car there was a vortech 350z that made 300whp few days before me..

 

also take a look at where you made gains across the entire powerband not just at peak hp. It sounds like you should have more gains in the lower RPM range. Also you can't really compare you numbers to other builds on here...different cars, different dynos, different days.

 

I came to terms with the the 350Z not getting much from bolt-ons when I beat another Z33 that had a 5/6 spacer, pop charger, tanabe exhaust, underdrive lightweight pulley, test pipes and some performance headers. My Z only has a Nismo intake, Nismo exhaust and lightweight flywheel and I beat the guy before his tune and after his tune. Unless you get an HR the non rev and rev ups don't really like bolt-ons. Some cases they actually lose horsepower with some bolt-ons so there really isn't any point to modify them to get performance gains unless your going with a turbo or supercharger. Or if you just want to hear the sound of a new exhaust or intake sound.

 

^^ This man speaks the truth. There was an old thread on here where some guy posted that he came to reality once he realized he spent like $3k on bolt ons for barely minimal gains, something around 20 if that lol. Pretty much if it ain't turbo or sc you're wasting your money. Sad but true =(

 

I knew I wasn't going to make big power but still more than 12whp... guess once I start fine tuning timing and it doesn't make anything else that's it...

Vortech 350z still only makes 300whp on this dyno lol

 

I forgot to mention the car made 213whp this year with all the bolt-ons and before the tune

 

Wait what? Most stock VQ35DE Z33s make around 230-240whp stock.

 

243whp last year same dyno 37c outside with nothing except bassani true dual exhaust

213whp this year same dyno with mods listed above but no tuning just factory at this point

250whp with the tune I did 15c outside

255whp with the tune the shop did 15c outside

 

OK so I'm not trying to be a dick but if this post and the other one after it is ssaying bolts on have minimal gains you guys must bbe doing something wrong. Where my car gets tuned stock baseline Z's make around 230. Right now with a valve cover gasket pouring oil soaked spark plugs that's I'm losing power with I have well over 50hp gained and that's just peak. I think you guys are doing something wrong.

 

Some exhaust and intake combos are worse than stock. But like I said "SOME" not all.

 

I'm gonna try to find a stock airbox or if I'm lucky an 06 box and try again

Does anyone want to share their knowledge on tuning timing? My current tune has pretty choppy timing I want to smooth it out ...
