And i had 2 problem with my car(g37 a/c)

First
heat issue
i had limited RMP at 6500
I didnt have this problem before but now it happened( it was hot somewhere 90 F)

second,
seat issue
With helmet on i cant seat straight
I am only 5 10

Is there anybody had same problem and Fix it somehow?

 

1. RMP? RPM?

The VQ37 has a known overheating problem; additional/larger oil cooler SHOULD fix it. Limp mode AFAIK, is a lower RPM isn't it? I havn't personally run into it so I'm not sure.

2. aftermarket seat rails may be an answer; if you are dedicated to tracking the car and are willing to give up the electric adjustments, you can probably get a few inches lower.


Additional recommendations for Streets of Willow:

Baffled oil pan
Oil sump

These are (relatively) cheap preventative mods that will save your engine on the Bowl; it's not really an issue at CCW, but it is in CW. I have had friends blow stock engines with oil starvation.

 

After some 2nd gear with high RPM i had that problem
Yes it was limited to 6500 RPM
My friend with 335i had a worst case what happened to him was gas peddal was not working at all after overheat.(CW)

I dont want to give up the comfort yet... not yet
I will use this for everyday for 3 more years.

My other friend with s2000 changed seat rail yet he still can use the stock seat so if we can do it with our g37 i will

Thank you anyway mike.....

 

i'm getting worried now...i took my G to streets of willow back in 07 and did not encounter limp mode...i was going nuts in a very hot weather...my car did not overheat but i wonder if my limp mode and termostat are working in order since this limp mode ordeal is a common occurance for people who tracked their 37s...help....

 

Limp mode is dependant on how well your car is cooling off, and how hard you are driving. Remember, that your perception of driving hard, may be someone else's perception of cruising.

The BMW definately went into limp mode; it runs with no boost and I believe 3000 rpm. The Infiniti will go into limp mode as well, but I'm not sure what the circumstances for limp mode is.

Hit me up the next time you go and I'll ride shotgun; maybe we can find an answer.

Also, what color are you cars? (jungwoo and CVT)

 

Yup, I was driving a student's C6 Z06 at a track on Friday and what I considered to be driving the car at 4 or 5/10ths he considered to be really fast

 

Has anybody installed an oil cooler yet?? If you have an oil cooler and track your car can you post up if it squashes the limp mode issue??

 

Not me but a friend who I KNOW abuses his car installed an oil cooler and problem solved

 

Nice...def on my list this summer

 

buttonwillow raceway, plan your next trip

 

i checked my oil temp with my accessport at the buttonwillow this time.
It started to happen when temp goes over 280F
Unless you have a extra oil cooler you can manage your oil temp if you have accessport.
have a fun at the redline time attck.

 

Seriously, you guys really need to put some extra oil cooler if you wanna track your G. Fun stops immediately once car goes into limp mode.

 

280 is way too high. Your oil is already acidic at that point....

What BLUESLATE said...

 

JungWoo (I figure you're a Korean fella), I recommand you change your oil as soon as you can, too. Like Mike said, your oil is already acidic...

 

I did already
thanks god that i had motul 300v... at least
haha
