I smell a troll. Can't believe no one else here smelled that nastiness. The extent of deez's knowlegde about Canzoomers products is nothing more than a quick browse of his website and some posts. I highly doubt he knows anything but malice towards the rx8.

Well thank you Sherlock friggin Holmes for that wonderful display of clue finding :p .

Troll BWHAHAHAHAHAHAHAHAH!!!!!!

Anyway. My CZ is still not very impressive but I still have some testing to do. Have yet to pull the intake off. I doubt that will do the trick but am willing to try anything at this point.

Bring on the Turbo Kits!!!!

Here's my timeslips from last night...

Ok, so which is which?

Velocity-8

The faster one is with the CZ on. :D

EDIT: I edited the pic too.

That info won't do much good in this thread. Although it's good info, the original poster was expecting CZ to propel the car into the high 13's!

I thought that yesterday was the 22nd of June? :D

LOL, someone else pointed that out too.

I smell a Troll as well.

Me or Nutz? I hope you're not calling me a troll.

I don't know much when it comes to the nitty gritty of engine mods and canzoomer's stage 1 and you can all say that I am wrong.

My understanding of deeznutz's dilemma about out running a 350Z is a joke. Racing Beat has proven on their website by use of an engine dyno, that air intakes and exhaust mods show very little gains (some even decreases hp). I'll give you the benefit of a doubt that your mods DO indeed give you the hp gains as they claim (for rough estimates sake... say 50hp). At current hp figures of 238 hp, that will give you 288 hp.

So you are saying to yourself at this point. "damn! Surely I can beat a 350Z!" And at first glance, yes, you should be able to out run the Z by compairing hp figures and weight of the two cars. But one thing that no one has factored into the equation is torque. We all know that hp gains do not amount to equivalent torque gains as well. For argument sake, again, lets say you gained 30 ft/lbs of torque. At 159 ft/lbs...that would be 189 ft/lbs. The stock 350Z has 274 ft/lbs. A difference of 85 ft/lbs.

Now for the summary. You gained 1hp over the stock hp figure of a 350Z. The weight of the RX-8 is 1384 Kg and the 350Z is 1451 Kg, again, the advantage is the RX-8 weighing in 67 Kg lighter. Last but definitely not least. The crucial bit of the equation is torque. A deficit of 85 ft/lbs! I'm no genius but from what I've heard, torque was very important in 1/4 mile times and acceleration.

Make from whatever you want of this bit of information. What I have tried to explain could be complete udder BS and/or I don't know what the heck I am talking about. But this is what I'm stickin' to.

If you gain x percent of horpower at a givin rpm, you will gain the same x percent torque at that rpm. This is because:

power = torque x rpm.

Also the rated torque means nothing unless you compare the gearing at each speed, since we are interested in rear wheel torque to accelerate the car. That is why power/weight is usually used since power takes into account gearing.

Torque_rear_wheel = Torque_engine x gear_ratio x final_drive_ratio

Yes! You can't just look at torque - you have to look at the whole system.

FYI, Your equation is right, but your description is wrong. What the equation yields is the frictional force between the wheel & the ground, not the wheel torque.

Take that that force and divide by the mass of the car, and you can make a very rough comparison between two cars on a gear-by-gear basis - "peak thrust" as I like to call it. But it's just that - peak thrust. The nature of the torque curve (Is it flat? Is it peaky?) will play a very important role as well.

Rotary787

You are right... that is rear wheel force. Remove the division by rear wheel radius for torque.

Torque_rear_wheel = Torque_engine x gear_ratio x final_drive_ratio

Force_rear_wheel = Torque_engine x gear_ratio x final_drive_ratio / rear_wheel_radius

You guys have already beat the 350Z! The RX-8 is a significantly nicer car, IMO. 20HP isn't gigantic, but for the modest cost this unit is to upgrade a small displacement NA car by that much, its a pretty economical mod. Quit worrying about Nissan's parts bin shared RWD sports car. Its fit and finish is leagues below the RX-8, and its not a very good value for what you get.

shhhhh!!! We know that, we just don't want them to know. k?

RX-8 friend

I notice the 350 is in a higher racing class (just watched the Watkins Glen race on the weekend). It is faster on the track, but those cars aren't "stock", even though the class description might say that. The 8s did well, 5th and sixth, as I recall. The 350s are getting faster/better, and sometimes run with the leaders. Recall one 8 won a race.

I saw Watkins Glen also. Here is the team that ran the RX-8's:

They took first previously at Phoenix.

Go RX-8!!! It's gonna take time for the RX-8 cuz it's a completely new design from the ground-up. Racing mods take a lot of time to get right.

My current avatar is my brother in his RX-7 GT-2 (NORPAC) car, racing in the SCCA national runoff's at mid-ohio last year. He came in 6th - not bad for not having any major sponsors and it being his first race there ever. What won his GT-2 class? 350Z. How many RX-8's? None, of course. Maybe this year?

You shaved .2 seconds of your 1/4 mile time and are still in the 15s? Eh....that's not a great example.

Velocity-8

Yup and if you look at my stock run from April I did a 14.8. Heat seems to be a bigger factor than tuning.
