I already started preping a stock one.

 

Keith how is the spool up on the s258, on pump gas?

 

23psi by 4500rpm on pump and 37psi by 5200 on race.

 

Magnus V5 Intake Manifold Dyno Test

Borg Warner S259 Turbocharger.

Test were performed on our Mustang Dynamometer MD-1100-AWD-SE.

Car: 2003 Evo 8
Engine: 2.0L
Fuel: 93 octane
Turbo: Borg Warner S259 / Open T3 .55ar Stainless Turbine Housing
Intake Manifold: Magnus V5
Throttle Body: OE Knife Edged and Radiused
Cams: HKS 272
Max Boost: 23psi on 93oct
Atmospheric Temp: 59Deg
Relative Humidity: 0%

The graph shows the Magnus Street vs the Magnus V5. Nothing else mechanical was changed for this test other than the length of the upper intercooler pipe to accommodate the intake manifold. Past 6000rpm the M-V5 took off for the sky.

I will be doing a full write up on the Magnus Manifolds against the stock one under a new thread. I will post the link as soon as I get it done.
We did test the OE intake manifold which yeilded very interesting results. I will post this with the Magnus manifold test thread so stay tuned!

The Kelford Cams will be in next week with dyno results soon to follow.

Thanks for viewing!

 

^Yeah!^

Do you know which size turbine wheel you had? 74 / 64mm or 69 / 61mm ?

The .55 housing is well known to DSMers. There are a few high powered DSMs around using the .55 housing. 653 dynojet hp from badman21 for example, shown here: http://www.dsmtuners.com/gallery/sho...mageuser=60835

Is this the Full-Race exhaust manifold?

Pretty darned good results I think, especially with the newer intake manifold.

Gary

 

Is that a full rece turbo manifold

 

Another thought: When you test the S362 it would be interesing to see how it does in the smaller compressor cover (7" or so across the outside). Might make boost a little earlier in the rev range, and a compact installation is always nice!

I can see 2 single scroll configurations that would be very interesting. One would be with the .55ar stainless turbine housing (if it's available) and the smaller (7") compressor cover - for us street demons. Two would be with the .70ar turbine housing and the "regular" (8") compressor cover - for the big numbers.

Then there's always twin scroll.

Gary

 

The turbine wheel is the 74/64. The smaller wheels we haven't tested yet since they are fairly new.

The link didn't work.

Yes it is a Full Race exhaust manifold.

The next turbo will be the S262 not the S362. Kinda the same thing though just a smaller cover as it seems you know.

I've covered Twin-Scroll already in another thread. The exhaust manifold was already on this car back when we did the S256 testing so there is no point in changing it now. Might consider it in the future pending the results of the S262. Might have an exhaust press issue and need the larger turbine cover to solve the problem but we will see...

 

Not even close. On a dynojet my car made 440whp. On this MD it made only 365whp. . .

Take these numbers and multiply by 1.2 and you'll get a very rough ballpark of average DJ #'s . . .

EVOlutionary

 

Well since nobody wants to send me a V2 intake manifold (offer still stands and I'll pay shipping round trip) we decided to do some porting of our own.

We will see how it performs very soon.





A link to the Intake Manifold Test Thread we did previously.
https://www.evolutionm.net/forums/sh...d.php?t=377793

So the remaining testing to perform on this car are as follows....

1. Kelford Cams compared to the HKS cams in the motor already

1a. Race gas for the final number on the S259

2. Pure Ported intake manifold... We shall see if our theories are correct and then we can get more aggressive with the porting to find the limitations of the manifold.

3. Borg Warner S262 Hybrid. If this turbo doesn't make the power we are looking for then we have already made plans to switch the exhaust manifold to a twin-scroll so we can run a larger a/r on the turbine side. The A/C needs to stay in the car...what a girl!

4. Pending the test results of the ported OE intake manifold I will also test it on a stock turbo Evo so all can see how the powerband is affected.
I think I'll do it on a Evo8 with and Evo8-Turbo and then switch the turbo out for an Evo9-Turbo. Anyone who knows us knows how much we love the OE Evo9 turbocharger. I unfortunately don't have an actual Evo9 to play with anymore to see how much more the variable timing will benefit from the ported OE intake manifold...Oh well.

As I said before the offer still stands on the Wilson V2 Intake Manifold. We will pay for round trip shipping...However, at this point because of the amount of testing on my plate and the order in which I need to do it in I would want the intake manifold till the end of the year. Being it is the end of the season it should be good timing anyway.

I also want to add that none of the testing we perform is in any way intended to harm or discredit anyone or their products. We try to keep the testing as consistent and unbiased as possible.

Stay tuned...

Some outside shots of the car that were requested.

 

Keith -

If you need an Evo 9 test mule, my car should be ready to go in a week or two. It currently has the green on it, but I also have a fresh stock 9 turbo that came off the car at the 2000 mile mark . . .

Jarrod

 

Thanks for the offer Jarrod. I'll take you up on that. Figured you might be up for it.
When you bring your car in the next time bring that 9-turbo with you and we will do some testing. Could also do the test with the FP-Green and see how it takes to the manifold also we shall see...

 

This is great that you're doing these test for everyone, Magnus vs. OE, Magnus vs. Ported OE, Thanks!!!

 

The S262 should be very interesting.

That link I put in post #35, I don't know, it works for me, maybe you have to be a dsmtuners member to see it - it's in a guy's user profile. I won't post the dyno here, this thread is for your dyno runs! Just wanted people to know that the little .55 a/r housing can put some power down.

Gary

 

Hey Keith, if you want to post up an overlay of my dyno graph vs. this one to show how dramatic the HP improvements are over a Green setup that is OK with me.

It looks like, compared to my car, this spools 1000rpm later, but makes ~70tq and 135whp more. . . I'd say a pretty good tradeoff!
