1/4 mile in south florida

germanattitud · 07-21-2011, 09:39 AM

J Spec Automotive Inc.

He's worked on my Z, and look at my 1/4 mile time in my sig.

The ECU starts to pull power at 220, possibly a little before but by 220 its seat of the pants noticable. Oil cooler barely helps in situations like the drag strip because of limited airflow... your mostly putsing around the return lane and pits heat soaking up everything, and the only time you have airflow you are at full throttle anyway... so let the car cool off to 180 oil temp before getting it ready to line up, so its hopefully still under 200 by the time you start the run.

And if your 60' isnt in the 1.8 or better, you need to work on your launch. I was able to get 1.88 and 1.89 on bald stock sport wheels/tires with a stock car, so you should be able to do better than that if you have some decent tires.

160F to 180F seems to be the sweet spot for my car for good runs, anything more than that and your ET's will suffer. There is definitely a noticeable power drop on the butt dyno above 200F. I usually wait a minimum 30 minutes between runs. Ideally 45 to 60 mins between runs for best results.

The tune should make a big difference with your mods. You should come up to PBIR/Moroso once your Z is tuned.

PBIR/Moroso?

Yeah, pretty much the only 1/4 mile track in south florida...

Ouch at 102mph...that's bad. I thought my 107mph was garbage, if I trapped 102, I would have traded the car in that day. However, I am willing to bet your oil temps were pretty high and the ECU was cutting power. Hell, my 107 traps were on 210-220 degree oil temps.

germanattitud · 07-22-2011, 03:57 PM

Temp was 220-230. Bradenton motorsports park has 1/4 track. Just put in my hfc and getting uprev tomorrow.

tranceformer · 07-22-2011, 04:55 PM

You're from the Tampa area?

germanattitud · 07-22-2011, 06:04 PM

Yeah I'm in sarasota. How about you? Heading to Tampa tomorrow morning for uprev.

tranceformer · 07-22-2011, 06:06 PM

I'm in the West Palm Beach area... about 20 minutes from PBIR.

germanattitud · 07-22-2011, 10:19 PM

So how much difference did the flywheel do and what does it do?

Yes.

You are probably making about 10-15% less whp thanks to the heat and high humidity -- less actual g/sec of usable air are being drawn in because of heat expansion and high water content.

Over sucessive runs, unless you are misting the IM, it will be even worse due to heat soak. Your air temps are probably well over 120* F.

Go back in the "winter" and you will be happier with your time.

It's not my place to comment on this forum. I'm just so fascinated.

Are you asking what a flywheel does? You admit that you don't know how to do a burn out. Don't know how to drive. Spending/spent thousands on mods/tunning & I assume you don't know what they do, or if they are helpful. Am I getting this right?

McFrostyJ · 07-22-2011, 11:33 PM

Is there a better place for him to ask these questions and learn?

germanattitud · 07-23-2011, 06:39 AM

I was just gonna say, excuse me for not knowing every detail about mods. I know a few here and there but no need for you to come in here and start making fun of people. I thought this is a place for people to go to to learn and 99.9% are very helpful and I guess that andre guy is that .1% so my suggestion to him is...........get in your old 2008 350z and dream of having a 40th anniversary z. I rest my case lol.

I'm just a guest here, & should not abuse that privilege. It's just that your story started with a car being slower on hot days. As time went by, your story developed, at least to me, into fascinating & compelling reading. I'm sorry if I hurt your feelings. Please continue with your story.

stock flywheel is 30lb and most aftermarket are about half that. less rotating mass improves the responsiveness of the motor. I like it more than the high flow cats i have.
