LoL, I never checked the web for it. Years ago I made an exhaust for my freinds car, and when people would ask him where he got it he told them it was a Simmons-Racing pipe and the name just stuck ever since.

I installed my lightweight battery today.

The next step is racing seats.

What battery did you go with. I am thinking about changing mine, more because the wife always gets a flat battery to have a spare then to lose weight but if your changing something then make it better.

 

I went with the Odessey pc680. It wasn't as light as I usually use, but I wanted something strong enough to start it in the summer.

Simmons

 

you better move it or it might not last a year

 

No probelm, the car will be sold before that

Simmons

 

for anyone else who didn't RTFM the Odyssey dry cell battery is only rated for max temps of 113 degF without a metal jacket and 176 degF with a metal jacket, which makes it unsuitable for the engine bay in general and over the radiator discharge fan location in particular. The required alternator and charger output specs are a bit more stringent than most people are aware of too.

 

Have a melted one to back it up. All it took was one trip to AC. Thought it might've been a bad cell but seems it was due to under hood temps.

 

Where do you have yours located?

Simmons

 

Thanks I didn't know that.

 

I have mine relocated to the rear...

Right on target, especially around the charging.

Mark, what are you running these days? The PC680 in my CM car is past its prime (after only 10 months, according to receipt) and I'm looking...what do you know about the Shorai packs?

 

I get two seasons out of my PC680s (mounted in the engine bay) but living in OR keeps the uderhood temps from getting too bad, I suspect.

 

I have a Voltphreaks VPR-S40 lithium battery in the trunk, 9 lbs but full size battery capacity

 

grounding kit would help too correct?
definitely took a lot of load off of my battery...especially in high temps

 

Wow, I thought that I spent alot of money on my car




Simmons

 

The one they sell now is a bit less capacity and price (was 56 A/h and $2k msrp vs 50/$1.8k now), but I got a special deal on someone elses cancelled order and didn't pay that much

After all the aggravation I had previously with the Braille and Odyssey batteries I would say it was worth every penny regardless. It is without a doubt the best racing battery I have ever owned

Otherwise no, you don't really spend that much on your car

 

I couldnt get a braille 2015 to last more then 6 months until I started using a smart charger whenever the car is parked for more then 24 hours.

 

I get in and crank the key concern-free. It does have an auto shutdown feature if the voltage drops below 12.5 volts. So there is always cranking power even if you left the headlights on etc.

So you are saying that you have a $30,000 STX Rx8

I am going to try the Toyo's on my car next, I used to run them on my ST civic and my STR Miata and liked them. We will see how they are on the heavy Rx8.

Simmons

 

STX was always intended as a stepping stone for where the car will eventually end up, considering that I paid $25k new for it back in 2005 its safe to say that your number is a bit off

Don't forget the long tube header ...

 

I wasn't including the price of the car


Simmons

 

Wait...I thought ST* was cheap and Hoosiers were putting people into the poorhouse?

 

Does anyone know the part number for the decals we need to run for mazdaspeed?


Thanks,

Simmons
