I know they say 7.5 is rated at 450 hp but they break under stock hp

 

the open diff or tlock? I've never heard that it was rated to 450hp. But the people who break them, are normally the ones at the strip drag racing. And i've only heard of a few cases of people breaking the tlock at stock power. Many others have pushed over 200hp on a tlock.

 

Breaking is usually the result of had tq of launching the car (drag style). I rocked my stock rear for a couple years before finding a deal on an old school Eaton 7.5" rear.

 

Update
Just got in my ASP UDP 25%

 

Another update: today i should get my gauges i guess i will go ahead and install them today if i have time.

 

Update:

So gauges did in fact come in today. However i have the questions before the installation of them. Please correct me if i am wrong on how to do this!!

Ok so i plain on going out to advance auto parts and purchasing 2 add a circuit kits. Then i also plan on buying the appropriate wires colors (Black/Ground, Red/Power, Orange/Ignition switch.) I plain to find a fuse that will only turn on when the key is on. I will then make a harness of orange wires to connect to the add a circuit kit to that fuse. Then connect those wires to my gauges. The same thing for the power, find a fuse that is always gives power, put the add a circuit kit on that fuse make another harness of red wires then hook those up to my gauges and sensors. Then ground each sensor and gauge. the gauge ground will have a wire harness that will ground to one piece.

My main concern is the amp ratting for the fuse. It says use a 3 amp ratting. Do i still use the 3 amp ratting fuse for 4 gauges into one main source?
Is there anything i am missing?

Thanks for reviewing this and giving me feedback.

PS i decided to use Glow-shift gauges because my friend has been running them in his ecilpse for about 3-4 years and they still work good.

 

another question. I forgot to order a Water Temperature Sender Attachment for my upper radiator hose. Does anyone know the dimension of the upper hose for i can order the right part. Or to save me money how can i install the sensor into the hose without having to worry the pressure is going to blow the sensor out.

I want to say it a 28MM Hose?

 

Is it an electrical gauge? If it is, just run your connection to the top of the coolant T.
