By looking at the photos, I would have to say that the biggest HP advantage is going to be had by the fact that there is not a cat present in the down pipe at all. With the catted down pipes, the gains will probably be less than 1/2 that of the catless. Can't wait to see a dyno comparo.

100 octane, jsb2h(r) and catless downpipes vs just a procede?... what is wrong with you O-Cha?

I said nothing about the total power, I said the CURVE looked way better.

K, stock downpipes with juicebox has a lot less torque, the upgraded downpipes have a huge impact in broadening the powerband with earlier spool and the ability to maintain boost longer. Shiv's car had a flat torque curve like that with his happy meal, it's the means of controlling power output that you are seeing directly translated into this dynograph.

I would approximate that when someone (besides maxboost who is the only one right now) shows up w/ downpipes, 100 octane, and procede that should look pretty damn nice too~

Don't get me wrong, this turned out to be an elegant dyno run, but you have to knock procede everywhere it just gets frustrating lol.

JB2H+DP FTW.

Ok, I know most of the acronyms but never knew what FTW means?

Again I was not referring to total power but the curve. Something else I found amazing was that there is no boost spike at spool up, unlike another tune. I've always thought less of the "purely resistor based" tune, but I swear the longer I go the more I go I'm not bashing, I'm just noting the things I find interesting to me.

No doubt.

Has anybody done a dyno of just the JB2H on 93 Octane, all else stock (stock exhaust, stock intake, stock DP's, etc)

Hehe it's not purely resistor based. I've always said we use many components, it takes over an hour to assemble each. And that is by a professional assembler!

Here is a run that is pretty stock, but he left it in SAE and had the 2nd cats deleted. Maybe those two cancel?

http://www.e90post.com/forums/showpo...33&postcount=1

JB2H is around 11-12psi so I'd expect 320-340rwhp and 335-355rwtq depending on octane, weather, etc.

There is no boost spike at spool up in v2
That was a trait of v1 of the PROcede on purpose, giving the low end grunt and huge torque below 3500 rpms.

Just curious, have you driven a v2 or even a v1 PROcede car?

Yes I have v2, and that's not what I've heard about the DP with procede, if I remember correctly schneid and down4it both had huge spikes with there dp/exhaust.

My turn, do you have a boost gauge or do you just assume there's no spiking.

Sorry terry.

Yeah, I remember reading that dyno.

Like Adam's recent dyno though, I don't know if that dyno is valid.
The numbers vary so greatly and flopping between stock and aftermarket filter, and open and closed air lid I think throws the ECU for a loop and gives greatly varied dyno results like we saw in that dyno from that link.

I'd like to see a JB2H only 335i on 93 Octane on 2-3 straight runs, no fiddling around with the air box, filters, gas mixture, etc.

I agree with you, I think we'd see:

325-335 rwhp
340-345 rwtq

on average...if on 93 Octane.

I wasn't referring to having DP's with PROcede, I thought you were referring to just boost spiking.
No boost gauge, just datalogging on stock DP's and exhaust.
And there is no map for DP's with the PROcede yet.

There's tons of spiking with V2 too. Get a boost gauge and quickly roll on the throttle in second from around 2k, you will have a nice surprise. Log it while you're at it and you'll have yet another. Then do the same thing but shift quickly from about 6k keep partial throttle and ride the clutch a tad.

If you do that you will see why It's a point of interest for me that this product is not spiking even with DPs.

PS you don't actually have to as I will post a video sometime in the near future bur my gauge has been out for a while for stuff.

Well I have an auto so I can't ride the clutch at the shift point.

But I have datalogged in many different scenarios, from full on launches from a dig all the way to redline, starting at 1500 rpms in 2nd and going to redline in 3rd, starting at 1500 rpms in 3rd and going to redline.
Starting in 4th and rolling on the throttle.
On flat roads, going up hill, going downhill, etc etc.

I have peak boost on most of them of 14.1-14.2 psi and "spikes" (if you can call it that) of 14.4 but always just as I'm lifting off the throttle, which is normal in turbo cars.

And I'm on 91 Octane (actually like 91.2 right now to be exact).

Sorry terry.

to be fair and have an apples to apples comparison, both schneid and down4it have HEAVILY modified cars, included in both ironically is an I/C and CAI which are mods that Shiv had REPEATEDLY advised about using caution in Torque values. Now we can certainly determine a common denominator on both of those cases mainly the mods, your car on the other hand is stock,correct?

and another pertinent point is, schneid had a boost leak which was only discovered after the install of V2, it turned out to be at the I/C outlet hose.
