So I have a greddy TT @ 9psi, stock internals, Emanage ultimate, fuel return, etc. Dyno'd at 406.9rwhp and 375.9 ft lbs. Stock clutch/flywhel.
My car honestly does not feel like it has close to 500hp. To be completely honest, the torque feels weak compared to when it was NA w/ mods.
It feels like it takes forever to spool up in any gear besides 1st. It feels like it has a lot of lag in all gears (except 1st). Before anyone questions my tuner, Sam @ GT Motorsports tuned it so I'm sure he knows what he's doing.
Do you guys have the same problem or are you guys on and off @ 3k rpms in 2nd gear, 3rd gear? Give me some insight on how your car feels down low please.
I feel like I've wasted money on this thing.

To make things worst my friend with a camaro SS only trapped 1mph slower than me throughout the night and he has 330rwhp.
Real cool.

 

Hmm, not sure what you mean by "my car doesn't feel like it has near 500hp" becauyse it doesn't!

Sam is definately an expert with these motors, but I can't say I've ever experienced a weaker torque feel in a turboed z vs NA...

 

Well, at what rpm are you stepping on it? If you step on it at 2k rpm in 4th gear, your not going to feel much until you get over the lag and up the rpm. Take it to like 3500rpm in any gear and step on it, and you'll get pinned to your seats. Don't just step on it for a sec and let off. Step on it and hold till redline. I get pinned to my seat everytime I step on it.

About the trap times, what mods does the camaro have and (flaming or anything) but how good are you at driving?

 

Are you going WOT when you get on it? Cause I know on my base tune I dynoed and 413 hp and when I mash the gas in 2nd and 3rd I can feel a s**t load of torque !

 

Well I have yet to dyno, waiting on my exhaust BUT this car feels nothing like stock!I cant even floor it in 2nd with loosing traction. My stock G never did that!

 

Edit, my kit is a APS TT kit.

 

I think your butt dyno is broken.

 

well, you're definitely screwed up in the head if you think the torque feels weaker than when you were na

of course it doesn't feel like 500hp, it's 400whp. do you really know what 500hp feels like anyways?

if you can't live with that lag, maybe you shouldn't be turbo? Its very MINOR lag.....on that kit. (though I beat a g running 11psi on the greddy kit, i hit full boost before him very slightly)

 

the greddy kit has bigger turbos than the other TT kits right? I've heard there's more lag with it than other kits.

maybe you're thinking the throttle response isn't as sharp as it was when you were NA?

 

Your numbers say it all. You are definitaley getting more torque, maybe you just need to adjust your driving style?

 

If you cant break traction in 2nd gear then there is definately something wrong with your setup. A stock 350z should even be able to break traction in second gear. Sounds like a vacuum leak but Im no expert so hopefully the guru's will chime in.

 

sounds like your too used to driving around in V8s... keep the RPM up high, thats where DOHC engines make their power. When you go to race someone, you have to downshift and start out around 4500-5000rpm to get the power when you need it. take the engine all the way to redline and shift quickly.

a 400rwhp Z wont be a ton faster down the dragstrip then a 330rwhp camaro if the camaro is setup very well... but why dont you guys line up from 60mph and go from there and see if he can keep up.


BTW maybe your clutch is slipping too. Definatly you should upgrade that and put another 30-40hp into your car... that extra 30-40 will make a big difference. i only had 430rwhp and drag radials and i ran a 12.1... there is a local guy who can drive well around here running in the 11s at mid 400s

 

Yea I think i read that post wrong forget what I just posted.

 

My car feels like it has torque for days. Once the boost kicks it just pulls and pulls.

 

Well for starters, I'm no expert at driving but I'm not an idiot either. I used to own a GS-T w/ mods so I know a thing or to about turbo lag. I'm not stepping on it in 4th at 2k and expecting it to haul *** either but...It just doesn't feel like it has 400rwhp. I can't break traction in 2nd either (unless your talking about a 1st to 2nd gear shift). Even if I downshift into 2nd already going like 50, it won't spin (with VDC off of course) 1st gear spins a little towards redline but after that there's never any wheel spin. Even if i mash it @ 4k rpms in 1st it won't spin, it will just take off.
Also, I have a TD 2.5" exhaust with kinetix cats but I didn't think upgrading to test pipes would make that much of a difference all around.
Another thing, if the stock clutch was slipping, would it be noticable (pushing the gas and it revving up but not going anywhere or the clutch smelling in general?)
Don't get me wrong ,it feels nice up in the higher rpms but anything below 4k feels sluggish. I figured with the V6 + TT it would just take off at 3k rpms. Can you guys really spin 2nd just by stepping on the gas?

 

Yes, but not until about 3500 rpms.

 

okay, for one thing, if you downshift to 2nd at 50mph, you're past your torque peak anyways, so it's not going to spin

If anything, it's more likely to spin early in 2nd gear than later simply due to the torque available.

 

I had the impression that with 406 to the wheels I'd be able to at least break lose through 1st at anything above 3500 rpms and even in 2nd gear if I was high enough in the rpms. I can't even break lose through 1st at all until redline where it breaks lose for a little bit.
The SS just has headers and exhaust (still has his cats)
I know when it was NA I could downshift into 2nd and at least the tires would screatch but not it's nothing. It almost feels like something is restricting it (like traction control or something) but it's obviosly off....

 

Looking at the dyno sheet torque peak is at around 4.5k and if I downshift into 4.5k it still won't spin. Hell if I take 1st , 2nd gear up to 4.5k and mash it, it won't spin.

 

Maybe you just have awesome tires
