Does anyone know a better oil pan for this VQ37 engine in the market than the Greddy one ?? All of us, please let me know if you do .......

I found AM Performance oil pan. The baffle plate design looks pretty killer and awesome but costs 1 grand. Worst than that, these AM performance people NEVER replied to my emails at all. Their telephone number in Scotts Valley, Ca is disconnected as well ......

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?

Yes, But has anyone ever officially and practically tested any of these numbers ? I love to know.

Also, I assume that these are rear wheel horsepower that you are stating. I am looking for about 480 - 500 reliable whp for my future FI . I can only hope to get up to 193 mph for my Z at 500whp, then I will be so much happy.

It kinda pisses you off when you can't match the top end of the station wagons and sedans.
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 best to do is to try it out and see the real result. Like I said before on my previous post: I paid a professional driver to test out my GT3 RS MK2 for absolute top speed. The car was bone stock and had only 450 hp at the engine. Indeed, the guy topped out at ~194 mph. Now, that GT3 weighed only 3022 lbs. However, I think, but I am not 100% positive, that my GT3 had a much better aerodynamic over this stock 370Z and that's why not much hp needed in order to get up there..... and it got up there pretty strong with not much struggle.

You mean someone did actually drive the vehicle and had it radar read the top velocity like what I did for my GT3 Porsche 3 years ago ?

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.
