Gas Pedal Delay

RedBullRR · 05-09-2011, 08:39 AM

I have read, that a lightweight Pullie will resolve this initial lag is this true?

A friend of mines hooked me up with Stillen lightweight main pullie and under drive pullie. I'm skeptical about these pullies. Most likely will be installing just the main crank.

I've read on here it will give you an initial 10 foot pounds of torque helping eliminate this laggy feel launching in first.

Thoughts?

I think a pulley will liven up the engine response a bit, but I don't think it's going to cure this lag. It seems to be like it's something electronically related.

I'd like to see what some trusted tuners say about this. I wonder if Sam at GTM or Trey or Sharif at Forged have ideas.

DIGItonium's sig shows that he's got NST pulleys on the car and yet he's still got the problem. If oil coolers, pulleys, intakes, a tune and Nissan dealerships can't fix the issue then I'll buy that it's ECU-related.

I was out the other day about to merge (Honda with a tin can exhaust next to me) so I floored it to jump ahead of him and there was a good 3 sec delay ... really disappointed. Especially because in my head I was gonna own this guy, but by the time I accelerated I had to slow back down to let him in!

Had the same problem, I thought something was wrong with the car since I have only had it for 3 weeks. My 350zRoadster was fast off the line, my 370z was sluggish. I turned off the VDC or traction control, problem solved!

The traction control on my 350 Roadster was not this tempermental but I can honestly say it make the 370z feel like it's straining. I turn it off everytime i start the car now. I wish I could reverse the toggle so its always off and turn it on when I need it.

Thanks for the feedback...the mystery continues.

Then you are having a different problem, or at least a watered down version of our problem. This problem we are referring to is irrelevant whether you have VDC or SRM on/off.

^^^yeah i had VDC off today and it fell on its face several times^^^

Does anyone know if this is happening to the Nismo at all?? I don't recall seeing anyone in this thread with a Nismo version and I'm SERIOUSLY considering a trade-in.

WOW, sorry to hear. Thank God I am not having that problem. Yea that would really suck.

I haven't heard of many people in this area (south florida) experiencing this much. I know I haven't. Hell, I don't even think I've ever seen my oil temps go above 220, even when pushing the car.

off topic, do you work on 136 and 14th st by the HBO building? I rarely see 370Z's here and even rarer that I see a red one

gaveup · 05-12-2011, 08:57 AM

Also, just a crazy thought, but since this delay or any hanging revs seems to be caused by higher oil temps...has anyone thought to hook up a dummy sensor to the ecu that always would read 180?

I know there could be some repercussions to doing this as many people aren't sure exactly how the ECU works in terms of what's too hot or what it does to limit performance. But that would give you a surefire way to test and see if it is 100% oil related.

m4a1mustang · 05-12-2011, 08:58 AM

I think we've already established that the oil temps aren't the problem, as I've had it happen when temps were sub 200* in the dead of winter.

oil temps sub 200* are a problem in itself.

synthetic only works properly over 220*

Not sure if srs.

That's a load of crap. There are plenty of performance cars that run full synthetic and never see oil temps above 220, and it certainly functions just fine.
