its cool bro i appreciate it. im not fully up to speed with everything in it hence why i havent tuned anything myself yet.

I'm stuck in Afghanistan at the moment but I will def post some vids of top speed after I get this done.

Sounds like you nee 3.3 final drive, I start in 3 gear at 80 and end up in 5 gear by 150.

Which RC / FOB?

Not sure how to correct the issue people have been switching final drives on Z's for years. At my power level I need it the stock gears are just to short for my power level. My speedometer being of a little is something I am not worried about it can be thrown off just by changing tires.

High boost 647whp 613TQ link to my thread is in my Sig

Squeeze definitely has a 200mph car. Aero is .29 cd. The GT500 is a brick in comparison, and does not make the kind of juice Squeeze is making (pun intended)

Just put a fan on the oil cooler you have now. Also where did you mount the cooler? If you put it on the drivers side or left side of the car I front of the radiator and AC heat exchanger the fan for that will suck air through the cooler when the ac is on and cool the oil by 200 degrees. If you have some way to turn that fan on while the AC is off that would solve some cooling problems. Also adding a fan to the oil cooler would work as well.

Yet at those speeds it would be nice to have two coolers with fans.

I think the best would be a cooler in each side of the front wheel well with an hole cut to let air in and one out with hose that goes to cool the brakes and puller fans on both. That way the faster you drive the more cooling and even cooling when you slow down.

If you factor in 15%-17% drivetrain lose that would put around 750 crank. I have no doubt that the car can do 200 MPH just haven't had the room to do it.

I have done 170-175 and the car get's there quick.

The driveability of the car is perfect like it came that way from the factory. The tune is spot on no erratic idling issues hard start issues. My Oil temps in the summer stayed around 180-190 W.O.T after a bunch of pulls 220.

since we are on the topic of FI and high speeds i got a good question. i was told that with my 7AT transmission and going with a TT setup i would basically lose my 6 and 7 gears. since the stress of high rpm in those gears + added hp/tq would blow everything up. this was actually my main reason for not going FI since like you all i enjoy touching my speed limiter and cruising at high speeds on the highways (especially long trips) plus the other problem is that GTM's stage 4 AT tranny is $8k with labor and still was told the higher gears may not be completely safe. :shakes head:

anyone wanna help shed some light on this? you guys seem to know a good bit about FI and high speed.

I'm definitely no expert, but pushing a lot of torque on the overdrive gears, gears that are not built to handle the abuse the first few get, they may not hold up very well. My shop was hesitant to run my dyno's in 5th because they didn't want to put that extra wear on the gear. Again, I have no direct experience with the failure of the gears.

and thats where i decided maybe no FI since i like going fast lol if there was more info and tests on the GTM stg 4 tranny maybe i'd go that route. til then it's wait to get a GT-R unless i just TT my Z lol

my original goal was 550 to 600WHP but at those numbers the TQ gets up there and i'd probably blow my transmission in a week.

You have to change the values on the digital speed counters. Since the car is trying to read 3.629 you have to change that value to 3.3XX, also if you have changed tire sizes then you need to update that as well. I thought that this setting came with the handheld or can be done when you uprev?

fellas I know its not optimal for me to start in 6th at 80 mph and go all the way up. Iv had my car for 2 years and iv tried things just because I can. If I were trying to get to 160 faster id start in a lower gear. I just wanted to see how it would start to pull and not stop pulling until I let off the gas. I chose to stop at 160 when i did it. With that being said I think i could redline this car in 6th gear with enuff room. Im at 540 whp on a gtm twin turbo. all stock aero besides a vented hood. the car did 160 before the turbos. I now have 200 more horses.

According to my spreadsheet.

640hp - 210 mph Rev Limter Governed
500hp - 210 mph Rev Limiter Governed
450hp - 208 mph
400hp - 199 mph
350hp - 188 mph
300hp - 176 mph
280hp - 170 mph

Based on the math anyways.

wouldnt weight also be a factor in this or are you just setting one weight in the equation?

i mean with higher HP youre typically adding weight with engine parts, turbos, coolers, etc...

i know it may not matter since its just a simple equation for fun purposes but just a thought lol

Now can you do the math based on those power outputs & speeds and add distance to speed?

:iagree: This is what I thought, and the most awesome answer:

Can you post videos??? How does the car feel at 165MPH?!?!?!

Honestly, you need a larger, or 2 larger oil coolers, and I'd recommend a different front bumper, maybe the Amuse, Stillen or Nismo to allow more airflow. The stock bumper blocks A LOT of the surface area of the cooling apparatuses.

Take a look at the spreadsheet I put up in my thread.

These values are calculated taking into account weight (I had it set at 3300 lbs), wind resistance (assuming 0.30 CD) and the torque curve of our cars. What I did was took a stock dyno chart and then scaled it up to get the desired peak hp's. Again not entirely correct but I believe is a valid assumption as typically the TQ curves are just magnified when adding boost.


To add to my other post.

Time from 0-160
640hp = 12 s
550hp = 14.3 s
500hp = 15.85 s
450hp = 17.9 s
400hp = 20.5 s
350hp = 24.2 s
300hp = 29.7 s


Again just based on the math.

At speeds such as those weight really plays very little in determining power to overcome resistance at those speeds.

Yes it was all done with RWHP numbers.

why are people so amazed when someone puts the did 130+mph? (not directed at (not directed at poster just general question) lol i feel weird that when i say the speeds i do and get looks from other Z owners like "what didn't you know it could do that?" :bowrofl:

i hit my speed limiter a few hours after i bought mine on the 1200 mile drive home i had :tup:

ok thats cool. i cant look at it since i'm at work and dropbox is blocked due to it being a online storage type and possible viruses etc... :shakes head:

i think the GT3 is also .30 drag coefficient as well. and to be honest .30 isnt bad at all considering the GT-R is .26 and thats really good. the new lambo aventador is .33 DC so the Z is better than a lambo yea i said it lol :bowrofl:

A rough estimate (using the 370z gearing) shows it would top out right in the ballpark of 198-205 mph. This is assuming it has the same 0.30Cd.

The lambo is so bad because look at all that surface that the air brushes up against, haha.

What spreadsheet? A Bugatti Veyron needs 250hp to reach 155MPH

I kind of agree, but at the same time, power will always trump all... The weight of a full blown turbo kit isn't going to add 500 pounds vs the 200-300 extra horsepower you'll get.

At speeds close to 200MPH your bigger issues SHOULD be aerodynamics, BRAKES, TIRES, and gearing... Does anyone know if the theoretical top speed of the 370Z is even 200MPH? I would assume the gearing wouldn't allow it because of how short the gears are...

Google provided me with this:

Again, that's just based on math... I doubt the car will go that fast though...

God bless the crazies in Germany that want to take their 370Z TO 200MPH... I wouldn't feel safe, nothing in the car is designed to go that fast

just stating facts lol i like to :stirthepot: for fun :tup:

I posted a link to it in this thread already, but thats in the ballpark of what I figured . Take a look at it and let me know what you think.

No, I know it will go that fast, and faster, I have gone 125+, but only for a short period of time, cruising at 130+, God bless Germany, lol
