RPM MSP header dyno results

[RPM Motorsports]

So we finally got the header bolted onto Dan's MSP and took it for a few dyno pulls.
First we dyno'ed the car in its stock form...EVERYTHING was factory.

We saw a max of 155WHP and 167ft-lbs of torque over 3 pulls

So the only thing we changed was the RPM tubular header

And we got 162WHP and 176ft-lbs of torque over 3 pulls

Remember that we had the factory J pipe, cats and exhaust system still on the car with a factory airbox and old air filter still on the car.

Not too shabby for everything else being stock....now we gotta see what the Turbo-back 3" is going to unleash!

Nice

Oh I should also mention, I've never driven a MSP for an extended period of time before and even I noticed the power difference once the header was installed, much better lower rpm torque in traffic

 

[31R]

Not to bad! Wonder what it will be like on a slightly modified MSP.

 

[SeR_Cyclops]

it will increase alot if you free up the intake and exhaust.

 

[SwirlFX]

it will increase alot if you free up the intake and exhaust.

exactly what I was thinking. All that matters is that it flows significantly better than stock.

Just wondering...do you need to take the turbo off to change out the exhaust mani?

lol... yes. That's like saying "do I need to take off my pants to change my boxers"

 

[orng1]

It could be done but it would make things more difficult. But I can see it happen.

 

[SeR_Cyclops]

lol just its alot simpler just to unbolt the mani and unbolt the dp and remove the radiator undo vac line and pull the whole kit and kabootle out. (spelling lol)

Ok, maybe I'm still misunderstanding what your saying but from what I read you would rather spend $550 on a stock performing exhaust manifold that looks a bit better than an OEM heat sheild without ceramic coating than spend $750 on a tubular header that is equal length with ceramic coating inside and out?

Now I'm not saying that Steedspeed's manifold will not out perform the OEM one, but it really doesn't make sense to me to go through all that work and machining to get a block of metal with some runners carved into it that resemble the inside of a stock cast manifold.

I found this quote by RPM on the TOProtege forums. I haven't really had a lot to say about this manifold and respect any craftsman who is working hard to make a new product but this kinda ticked me off!

For your information RPM, my manifold performs much better than stock and is not just a better looking version of the stock manifold. I am also quite sure from our dyno result it will perform at least as well as your pile of spaghetti and it will not crack the way yours will with all those thin slices of tube grafted into the design. If you take a look at the close up pics of my manifold you will also see what a weld is supposed to look like when done by a true artist like Chris my welder. I can clearly see that your welds are done too cold for a start (crack). Anyone buying one of these should delete the ceramic option because it is difficult to fix the welds when you have to grind off the coating first. If you really wanted to make a nice tubular you would have done better to copy the MAM version which to my mind is a very nice design and is arranged so that expansion will happen in such a way that it won't be trying to pull itself apart like your version

RPM I suggest you show a little more courtesy toward someone who has never said a bad word against you despite you being on here selling product without AV status.

 

[K. Soze]

Yikes. (ohsnap!)

Steedspeed does have a valid point.

Lets not turn this into a whos manifold is better thread. Time will tell if RPM's Manifolds live up to our expectations. There arent many manifolds out there so we have to live with what we got. If you dont have much cash to spend then steedspeed is the route for you.


The numbers look good so far. How long till you get the exhaust and intake on?

This header was a prototype, I welded it myself. I am not a welder...as you can tell I'm not a very skilled welder either lol.
Our 2 certified welders who work here were away when the header was ready to be finished. I did not want to wait for them to come back so I started welding it myself, they both tell me I had the amperage set too high and put too much heat into the material. Its a solid peice, but its only a prototype. It did what we wanted it to do.

The "flimsy" material we use is Schedual 10 Stainless, which by the way is 3-4mm thick. Not crappy ebay 16 gauge headers which are 1.6mm thick.
We are going to offer a lifetime warrenty on these headers from cracking, thats how confident we are in the quality of them.

Our one employee is an NHRA certified chassis builder who fabricates things like this everyday:

Thanks for your concern about our product and good luck with yours

 

[nvmsp]

pm me a price. steedspeed never pm'ed me back so to the quickest seller....(enguard)

 

[Outlawstar98]

nice! cant wait to get it! RPM you rock! lol

Dan reserved one for me hopefully, can you ask him if he did for me RPM?


And i cant wait for the exhaust. its turbo back right? if so thats the one im buying

He was courteous. all he commented on was the initial impression upon looking at your header. LOOKS. what are you a ricer. looks do not matter. results matter. Lets see your dyno. It's gotta look better than your manifold does.


Oh and on a note of respect. RPM did in no way insult your manifold. Pile of spaghetti vs Chunk of metal.

Beauty is always in the eye of the beholder. I find the RPM ugly and you find mine ugly. RPM was rude about my product in this and some other posts so I decided to call an asshole an asshole. I never commented till now but I will not stand by and have some guy put down my product. Where are the dyno charts by the way?


Lets face it you are an RPM nutswinger so keep on swinging on those low quality nuts
