|454C10||a 240z is 2400lbs with fuel, I added another 200lbs with bigger stuff (engine, trans, exhaust, tires, radiator, diff, no2 system......) Plus I weigh in about 200lbs. So 2800lbs total car weight with driver. et is a little slow as compared to the trap speed due to slow shifts|

2,355 lbs (American) Datsun 240 Z. F birds close enough!!

love to see a vid of it hanging tires on the street, on dot tires
so a 240z is 2200lb's?

Starting with the right tires. You can put all the torque to the ground
and leave your combo in the dust on acceleration.
You cannot make a car faster by killing off power. Like overcamming it.
The big top end will not be realized with the 292H with this exhaust system.
My car will yank the front wheels of the ground from a light in all street trim.
The way I run it at the track is the same as the street setup.
Its just that the track is the right place for that.
You want to put garbage tires with no traction on your car go ahead.
You will never make up the difference.
you do not want to or need to kill off low mid grunt.
You just need some basic traction.
this car weights almost 1000 lbs more than a 240Z w a SBC and 4 speed.

your 84 z will be happy without a little low end..
unless oh course you've reworked the whole car..
the facory set up.. a weak v6 with iroc wide tires can turn them over.lol
the car will be faster on the street with a softer lower end, that'll get you moving, roasting tires=fun but not fast

The Y looks like this under the car
|11-19-2012 10:02 PM|
Well not really the same as a tri Y.
The Idea of joining the two banks together with this Y pipe is
1. It fits the car. A 2 into 1 exhaust system fits this specific car much better.
2. to make the total system exhaust system scavedging a lot better. (more mid range torque)
The engine sees it as of the header primarys are longer than they are.

My dyno tests were in the the mid 80s! But they were really popular in the mid 70s and early 80s here! and are still produced! they were also used on a lot of Honda 750 racing motorcycles!

|vinniekq2||PJ, when were the tri Ys popular? I think Jere made the 4 into1s starting 1964? just before my time...lol.|

F birds "Y" pipe is interesting, reminds of the Tri Y headers I dyno'ed the Tri Ys! The increase in hp and torq was quite a bit more then street headers and fell just short of tuned competition headers till they entered higher rpms! over 5500rs! I guess that works on the same principle for scavenging!
I never ran shorty's either.

|vinniekq2||454 that sounds like a 10 second car|
