Low end torque after mods

Sharpie711 · 04-04-2012, 01:50 PM

I installed post manifold tubes, K&N drop-ins, F.I. exhaust and F.I. test pipes. I feel like I'm missing some low end torque. The car does not feel like its pulling like it should. I have a Cobb access port for it but they dont have any maps. What would be the best solution? Thanks!

go get a custom dyno tune! should definitely help out

I'm thinking i'll just get them to use the access port i have and make a map for it. I just dont know where to go. I live in Charleston and the only place close is a place called Showzone...And to be honest it looks like a shack with old beat up imports outside.

I dont think you can use Cobb at all, They no longer support the VQ. Try UPREV.

they do.. but 09s only

It could be the test pipes and new exhaust affecting your low end torque. I may be incorrect, but freeing it up like that generally sacrifices low end torque for more power mid and up top. A tune could help, but it won't make too much a difference. Stepped headers help as well, but it's expensive and you already have test pipes. Cats may help build back pressure, but again you already have test pipes. M370,intake manifold is great for mid range torque, but not sure how well it does under 3k rpm

Thanks for the advice! I called Akuma Motorsports and they said they could make me an E-Tune that would free up a lot of my lost low end torque. They sounded pretty confident about it. I would take it to a shop but Charleston isn't exactly import heaven. All's we have around here are trucks and v6 mustangs with GT badges. The closest shop i would trust is about 6 hours away (Z1 Motorsports), so I'm going to use this E-Tune to hold me over until then. If this does'nt help even things out i may trade the test pipes for high-flow cats.

A tune will certainly help, but the lost power&torque low down is a by-product of test pipes i'm afraid

Someone correct me, but i only know the Motordyne pipe (ART) to actual combat this it's self.

Tuning is worthwhile, but i'd recommend you finish your bolt ons before getting the tune.

the art pipes just eliminate a little more rasp and the hiss... less backpressure = less low end torque.. theres no way to avoid it

Actually, they do, i've seen dyno's compared to cats and TP's, they do make more power/tq than cats and tp's.

making 2-3 more WTQ is not "combating" it IMO... but I know you gotta rep motordyne.

Zrider79 · 04-04-2012, 04:23 PM

There is more torque with art pipes, than a test pipe for sure !

Hey, Sharif @ Forged Performance is in Marietta GA!! I wouldnt go anywhere else but forged for my Z!! He has tuned 100s of 350z, 370z and GTRs. Why go anywhere else?

TerribleONE, i only rep companies who produce the stuff their marketing spouts

Check BiltHamber.com for another example

Anyway, i went and grabbed the 350z pics, i know nothing's perfect and i don't think you can gain much, but gain instead of lose is always nice.

Deltas Vs stock cats.

And for the gains over test pipes;
