Can someone please help me With some tuning stores for the rx8?

 

:D

 

Try dry ice, much much quicker...

 

Yes! I heard, but i don´t know where to get it...
If you use dry ice you just know it of with i hammer, right?

When i removed the amplifier in the rear the sound from the speakers in the front stopped to.. Is there any way to play with the front speakers without the amplifier?

It´s nice to play some music when going to tracks and cruising!

I've seen people use those cans of "air" that are used to clean dust from computers to chip that stuff out as well. Turn the can upside down and spray the very cold liquid on the sound deadening, tap with a hammer, should release cleanly.

Ice cream shops and your local supermarket / grocery store may sell you dry ice as well.

 

The whole car is stripped and now i´m looking for a roll cage. Sadly i can´t find any.. And when I find one they dont ship to Sweden

Do anyone have any tips?

 

I'm not a big fan of kit cages anyway - is there someone you can take the car to and have it built from a bundle of tubing so it fits the rules (if any), your body, and the car properly?

 

Yes i have.. But im going to drive on the road With the car to, so i need a cage i can remove 1 / year

 

Take My advice, the contact you got can weld in a cage for sbf approval or make an bolt in bar like mine. Your choise

 

I have talked With Mats and he can help me in Januari if i want to!

New coilovers on the way, so will not be this high for long

 

I've seen/heard occasional references to larger diameter catback exhausts providing reliability benefits by lowering exhaust temp. I'm looking for an excuse to add a 3" system behind my catless bhr midpipe but can't seem to find any hard data or even heard firsthand experiences in this regard. I can't put a lightweight system on since my home track has a strict sound policy and I'd like to keep the car somewhat civil on the street. I also don't want to waste money on a noise maker that provides no power, reliability, or weight benefits. Has anyone here noticed any positive effect aside from weight loss adding a larger diameter dual exit catback?

 

There are several other exhaust threads here to read. There are almost no gains (if remaining NA) to be had in the exhaust system besides removing the cat, and the weight savings from a single exit. You could get a header, but read this thread first, as well as every exhaust/header thread you can.

Exhaust is, while remaining NA, basically only for sound and because racecar. Minimal gains for some or a LOT of money. This has been shown by basically every vendor with their respective dynos for exhaust parts. They typically have single digit dyno increases quoted, and most experience I've read basically backs this up. The typical number of hp to be had with everything done is like 10-15. Maybe (30?) with a header with larger primaries. Most of the gains can be had by either removing the cat, or replacing it with a better unit (HJS?), which you've already done. The 30hp is best case scenario and either VERY expensive or will take some fab skills like the ones shown in the thread linked.

I can't speak to the reliability issue, as I've never heard it argued, nor am I experienced enough in the theory to make an opinion call. With the exception of removing a clogged cat, I haven't heard of an exhaust increasing reliability in the long run.

My suggestion is buy good tires and track time, your money will end up being better spent there.

Disclaimer: I DO NOT intend to represent myself as an authority and there are MUCH BETTER resources on this site than me. One thread has been linked. If anyone with more knowledge on the subject takes issue with what I wrote, tell me, and I will edit it.

 

I get tired of explaining it having done so on this forum more times than I have fingers, toes, and hairs on my head (I’m not bald either) so SEARCH

 

I tried, hopefully I didn't screw it up too much.

 

OK search ****.... instead of explaining it, just link me the threads containing hard data proving it's just for sound. I'm not looking for hp or tq info. Or just don't respond. If I didn't come up empty from a search, the question wouldn't need to be asked.

 

I doubt very much you will find "hard data". No one here does that kind of testing with regards to reliability. The builders who have the experience to give you their opinion have stated it already. Over and over.

Did you see Teams post count? You'll have to excuse him and the others for not wanting to reiterate it another time just because someone else asked as it also contributes to the clutter of the search results. You're already posting in a Racing thread about catbacks/exhaust. And not even a question related to racing, but reliability. You also won't get real far by asking for someone to spoon feed you the info, especially not that rudely and especially especially not with Team. He, as with most of the crowd here, doesn't suffer fools.

All the manufacturers for exhaust have dynos for their parts if they're HP producing... that's the whole point. Other than power/torque, weight, and sound, what exactly are you looking for hard data on? Clogged cats are typically the only(exhaust related) issue that will cause your engine to burn out faster. You could extrapolate that to increasing the exhaust flow and reducing EGT should increase reliability, but that would be opinion, and it would also be awfully hard to prove. Plus there's a point of diminishing returns. The opinion that seems to have found consensus, is the one that was stated in the original thread I linked, albeit with a few caveats. I wouldn't want to put words in others mouths, so I'll leave it at that.

As for weights: Stock parts weights

and some catback weights: catback weights

Finally, I found the best way to search this site is to do use google's built in "site:" phrase search. So, searching for catbacks would look like this in the searchbar:

site:rx8club.com Catback weight

Or whatever search term you wanted to look up.

Finally, it may not be the way you meant to sound, but try not to be a dick. No one here is obligated to do your research for you, or send you links, or even explain themselves in any way. No one owes you anything, you're the one asking the favour, and you'll find that how you go about asking will directly relate to how willing someone is to help you.

 

Oh, and I missed the fact that where this question should have been asked was in the Series 1 or 2 aftermarket performance modifications forums. Because the exhaust systems are, correct me if I'm wrong here, interchangeable, (this is wrong, they are not interchangeable) the sticky in the Aftermarket Performance Modifications for the series one entitled https://www.rx8club.com/series-i-aft...summary-16442/ will be the one to look at.

 

Catbacks are not interchangeable between S1 and S2. The tips sit higher on an S1.

I don't have hard data, but if you consider where the catback is, and where EGTs that matter are, I think you have your answer. Especially if you have a cat, nothing that happens after it has any bearing.

 

This right here is why I put a big ol' disclaimer on my first post. Thank you for the input
