Crawford headers, Megan aluminum radiator and silicone hoses in.


It's almost impossible to get a picture of the headers. You'll have to take my word for them being in.

 

Mounts for the oil cooler came today.







It is bigger than I thought but it will do.

 

I have not done much to the Z lately.

GCSPEC Midbrace



New exhaust went in. The AP Ti was just tooooo loud.













Came home and wired the cutout.

Cutout closed.


Cutout open.



Switch for cutout.

 

Sound clips?

 

Not yet.

A few new pictures from this morning.

 

Excuse the dumb question but what exactly does this do
Looks good

 

It allows me to be able to live with the car as a DD but get back the 30-40 HP the exhaust steals due to restriction by opening the exhaust.

 

Suspension braces came today.





And I had this done today:

 

 

Helpful AND informative.

THANKS

 

Do you have cats before that cut out?

 

No.

ART pipes where cats were.

From post 263:

 

Ah, I see. How's it sound with it open?

...yeah, I don't know that that exhaust cutout thing does anything...you probably loose a good amount of torque because of that. Assuming you arent twin turbo'd...then again, I didn't read the rest of the thread...And no, no exhaust will get you 30-40 horsepower on a NA z lol...

 

I did not say the exhaust GOT me anything.

I said it gets BACK the HP LOST due to restriction. I have the dyno (which HAD YOU READ) you would have seen that shows I LOST 36hp with the silencer IN.

I am having it tuned again Monday so I will have another set of dynos for you to ignore.

 

I finally got my oil cooler in.

 

Just noticed that "400" on the back. Whats the story behind that?

 

4 litre stroker that should have been in over a year ago will be in eventually.

 

Motor is going to another shop tomorrow
