i'm curious do the rrm products come with a dyno sheet? such as the intake, header, exhaust is what im most interested in.

 

RRM is not very keen on backing any of their claims, and as far as I know this is the only Dyno they've released. Is it worth the money? You decide.

As for the intake, not many people dyno their cars after installing a single mod, especially an intake of all things. So finding a dyno for the intake will be difficult, and even if you find one, there wont be much to see. SRI's are pretty much just noise makers.

Rock originally claimed the V1 SRI gave 10hp gains. After people demanded dynos, many excuses were made, arguments ensued, dynos were eventually promised, but never given. In the mean time, hundreds were sold, everyone loved them, but did they provided any gains? Who knows, but I promise you it wasn't 10hp.

Of course RRM has moved on to V2 now, but from what I've seen there hasn't been a dyno for that either. Rock has claimed that it's at least as good as AEM's who claim 5hp gains. This is reasonable, but probably still a high guess.

This really isn't an RRM issue though. You can really only expect about 2-4hp gains from any SRI, and around 5-8hp for a CAI, regardless of the brand. So if you're really interested in gains, you probably shouldn't even bother shopping for an intake.

As for the exhaust, it's an axle-back, and a very smart man ambystom01 once said something along the lines of "With an axle-back, you can throw a muffler on the end and increase the tip diameter all day long, but in the end your exhaust is still pretty much the same length, same route, same diameter, and has 2 or 3 cats further back which are the main culprits for restricted flow." In other words don't expect too many gains with RRM's exhaust either. But of course RRM claims otherwise.

We also have a dyno page that is somewhat useful, but you have to keep in mind that it is going to differ depending on the transmission, engine, and of course different dynos often give very different results. Many people believe dynos are not even accurate whatsoever.

There a few dynos with RRM products, but the above would probably interest you the most.


Here's some advice that will hopefully save you some money.
Don't be an RRM fanboy.

 

thanks for the response. i'll check out the dyno page! i know in an article that import turner did the takeda intake got around 5hp along with the borla axle back and the dc sports header...

oh im not a fanboy..just curious if these claims are actual or word of mouth..i have had my car for three years. so i know almost everything that is available.

what's the consensus on dc products?

 

One thing to stay away from is RRM Pulley ....

 

That is what I heard as well, they say it originally wasn't balanced...I figure it has been fixed by now, could not say yes or no either way, I don't want to bash a product I don't have, but I wouldn't put a pulley on the top of ny priority list over other bolt ons.

 

RRM pulley at least what i have installed has been good. No issues so far and Im at 98,288 miles.

 

No issues then huh? I haven't used it, but that turbo setup would be something that is on the wish list, heard it is good and puts you up around 50% from stock.

 

Is the RRM header any good ? I'm stuck between that one and the DC Sports one. Unless there are other other options out there that anybody knows about.

 

I've been using the first version of the Road Race Pulley and have had zero issues. Bought the pulley back in late 2007 as my first mod for my 2008 Lancer.

And I also have Road Race's turbo kit now.....still running like a champ.

I've got more mods on the way. Going for a slightly different look.

 

I just got the stage 3 package from them the other day. I haven't gotten the pulley yet, they were still making them. After the timing controller, piggyback ecu, and the intake it felt like it pulled way harder in the 3k-4.5krpm range. Exhaust and the pulley should be here this week.

 

just get their turbo kit it comes with the header i think. and 50 percent over stock they claim is awesome. thats on the wishlist for sure. plus you can just boost more after.
now i just need a job

 

any of you guys have something to say about the rrm grip springs? im pretty interested in them and they seem pretty solid from what ive read so far.

 

I have those as well. I like them, great ride, but like others have said I have a front end noise now, like a grinding/popping noise when its cold.

 

how loud/annoying is it? and does it go away as you drive more?

 

why is it only when its cold?
