RPM MSP header dyno results

Well, don't you have a boost gauge ?? that'll be more accurate cuz not all MSP come stock from factory at same psi boost rate, there's ppl that were boosting 4.5 psi stock so ........... the boost gauge should be more precise (mswerd)

I guess you might also consider the fact that all people claiming ther boosting only 4.5 and those boosting different are also using different boost gauges from different vacuum sources..which could make them all read different even if they weren't.
Ever consider that?
I would say they are all pretty close...the factory wouldn't let them go out too much apart....I trust their machinery and measuring more than the Autometer or defi or other Boost gauge that may be in your car.
I am sure the factory is a bit more accurate.

Where the hell are the moderators? This drama should have stopped at page 1.

Just telling it like it is. It is easy to beat stock manifold because the design is truly horrible. My manifold tested slightly better than the Thunder at stock boost and if you add the known improvement from the Thunder then you arrive at a similar result to the RPM and that result is also close to the MAM. Nobody is breaking any new ground here as far as performance goes. Naturally some higher boost will separate the men from the boys but stock boost isn't going to show much difference between any of the aftermarket manifolds.

I agree with this statement, but turbo's that will be used at higher boost will make the diff. so a stock turbo but higher boost would be the perfect match to test.

the curve or powerband and torque will give better understanding which one would be the best, soooooo the DYNO SHEET pls. RPM.
 
Is there any way someone can test these mani's at 10 psi and display
the dyno sheets???

True enough it's easy to beat stock. But on a completely stock car to see any difference you'd have to actually compare the dyno sheets and see where things changed and how much.

I've noticed my car boosts alot sooner and is much smoother through boost pulling all the way to redline for a change instead of kinda losing its umph. The tiny bit of extra power and torque is suprsingly noticable. I think it's mostly the freeing up of some torque and power in the bottom end. Definatly made me smile getting on the highway the first time.

I can't wait to see what opening up the rest does....I''m supposed to be getting a copy of the dyno sheets so I'll scan them in if joe/dan/luke don't get a chance to.I'll post stock, with header, and with header+turboback

10psi and what supporting mods? stock turbo? be a little more specific....or do you just want someone to crank 10psi off stock? I wouldn't. Don't wanna goo zoom boom boom.sorry. I'm a wuss.
 
Yay, finally found 2 seconds to snap a pic of these dyno sheets.

The software for this dyno was real crappy and printed some pretty lame graphs, but here they are:

This was one of the runs with our header on

This was a comparison between stock and with our header

"scratching head" hmmmmmmmmmmmmm

it be nice if you align all the dynos that are made(of competing many's) next to each other and evaluate , right ??

not too shabby, let's see exhaust and then intake right ?

with SMIC, CAI, Exhuast basic stuff... or maybe @ 8or 9psi.
 
Also I am not sure don't quote me but I think steed said his mani can
possibly out perform the others at higher boost I would like to see
facts before I put my money on anything....

thats what all of them say,

only the dyno can prove it
 
its not as easy as just everyone can just magically pull up a dyno. i know steedspeed was going to test it at 10 psi, and did, but then scott's car hit fuel cut, so they couldnt get an accurate number, so they just tested it on 8 psi i think. it takes time to schedule a dyno, and then actually have people who have the manifold to have time to be able to actually dyno it
 
Yep! Its not so easy to get the numbers people want to see. We'd all like a dyno chart with all the results from one car done same day on every manifolds with the results laid over eachother but I can't see that happening. There isn't enough money to be made to justify running a bunch of dyno runs to see which of us is 1hp higher than the other. If you like tubes buy tube and if you like the billet buy that. All the aftermarket manifolds are going to do much better than stock so you will most likely be happy with whatever you choose. If you really care about maximum power then build the motor up and run 25psi.
