All are similar. Whether its procede or AA, numbers are pretty consistent. So either UR's Dps are sapping Hp and Torque, we both have under inflated numbers , or you have over inflated numbers. Perhaps, my car was on the low side of stock HP and Torque? All i know is these are the numbers we got today.. uncorrected the difference was 7 whp and 9 wtq

I think its possible that the UR downpipes are not very effective.

But Shiv said that Walked U's car with PROcede V2 made 360 whp. And the thing is...PROcede V2 makes that power alone.

I'm confused. Basically, It look likes the DPs don't give any power on paper.

From some other threads, DPs are said to make about 20whp on an otherwise stock car...

This is an observation that I made as well.
On paper, there is a very little increase, but the track shows otherwise.
The turbos spool quicker and there is less of a lag with the downpipes and piggyback.

Right, but let's think of this realisticaly. Who is going to spend the money to have downpipes put on plus the cost of the product on a completely stock car?

Hmmm...interesting. This is about what I dyno'd at post Shiv's original XEDE installation (everything else stock) back in Dec., '06 as a beta tester -- 322WHP / 378 lb.-ft. RWTQ. I never got my car dyno'd after I did the XEDE-to-PROcede conversion, but always assumed that I was making at least the same if not more HP/TQ with the PROcede (based on what other PROcede 335i's dyno'd at and based on my own butt dyno).

btw -- this dyno also includes your Ultimate Racing Catless DPs as well, right ("Turbo back" exhaust)?

I really wonder whether all these DPs, exhausts, etc. really make that much difference after all. I'm really looking forward to installing PROcede v2.0 and going to the track with NYCGarbagePrince and a bunch of other 335i's in ~ 6 weeks...we're going to have a blast OWNING the Moroso track that night! :rocks:

[Boostin335]

thats why i question is it worth getting an exhaust + dp + intake and v2 or just getting v2 and not 'waste' my money.. this car has all the stuff the VQmotoring car does and is making 42 less torque then them and 30 less hp. Granted the only difference is an intake so -10 .. i just can't see how they are that different to cause a 20-30 hp and 30-40 torque difference... i just find that so hard to believe.


and the VQ guys i still wanna know how a stg 2 (intake, exhaust (NO DPs) and THE CURRENT PROCEDE) walked an E63 amg... lol i just cant believe that.. if its true god dayummm but ive drivven in more than a few e55s and i also have been in many c6s with intake/headers/tune/cam that are putting 400-450 rwhp.. and a stock c6 vs an e63 is a damn good race... i dont see how a 360rwhp car is going to walk something on a highway roll with 500 torque.

Well, don't forget that they dyno'd on different dynos, on different days, on different cars, etc. However, I know that the 335i CAN be modded to over 400WHP / 400 lb.-ft. RWTQ; the question is whether or not all that additional power is really usable? I too think that we're already pushing the envelope with just the PROcede v2.0 or those who have the AA XEDE, exhaust, DPs, etc.

Personally, I don't need to dyno higher than everyone else or have a crazy loud exhaust; I just want a PROcede 335i that's just faster than my current setup. What good is all that HP/TQ if you can't get it all to the wheels?

sflgator, I don't know if you saw my thread about the downpipe dynos, but i got a before and after comparison and I was really bummed. I thought for sure the downpipes would increase a bunch of power, but the dyno indicates otherwise.

http://www.e90post.com/forums/showth...1393&highlight

Like I said before though, the downpipes increase the throttle response and gets rid of lag. They're noticable on the track.

Yes, I saw your thread. Yeah, I'm not arguing against the DPs and exhaust; I think they do have definite advantages and possible gains, but I just think for a majority of ppl, the PROcede v2.0 may be more than enough. Any other additional mods on top of the PROcede or AA XEDE may be difficult to "feel" or even dyno. I spent a little less than $100 on an ITG air filter, and although I didn't fool myself by thinking it would add significant gains, I'm ok with it just providing higher air flow (although it could add a few HP/TQ but my butt dyno and ears don't notice a difference).

I agree with the "more than enough". I ordered the V2 just because I'd like to test this out, but I honestly don't know if I'll even go back to the Procede. I'm very content with the Custom Xede and I like the fact that it runs a little bit less boost and richer, yet gets better power than the procede 1.47. In other words, it's a little safer.
Who knows though, I might get the v2 and be like and say to myself that there's no way I'm going back to the Xede. Then again, I might try the v2 and say it's highly overrated.

[retrodrive]

From wat I understand, downpipes increase boost by 1psi on otherwise stock car. That is where they might have gotten their 20hp when they were testing.

I think same thing is going on with intercoolers.

I am too lazy to photoshop and overlay graphs, but I wonder if downpipes increase the area under the curve because of earlier turbo spool.

[NYCGarbagePrince]

Just ran a AA tuned 335i coupe 6mt from a roll.. Pulled him by maybe a half a car length if not less. It was so minimal it was ridiculous. I am officially pissed off about the money spent on exhaust mods. All bark... no bite.

You are both MT though, could be the drivers' factor on either side as well...

Sell you AA XEDE, and order your PROcede v1.47 AND v2.0...then, you might be happy!!!! :rocks: Not trying to start another b.s. XEDE vs. PROcede argument, so no flames please; just a thought.

so let me ask you a question and maybe help myself..


do you think i should justify spending the $650 on UR dps?

or just stay with v2?

I haven't bought either yet, hell I am waiting for my 335xi coupe to be built

If I were you, I'd get the PROcede v2.0 installed first; then, see if you're satisfied enough to stay with the stock DPs. You can always add UR DPs later.

He had a Procede before and did not get anywhere with getting a custom "tune" for his setup. He had limp mode issues among other things. Now we got his car running good and there is a power issue which seems to be attributed to the Downpipes.

I have said it before... IMHO i dont think the turbos can produce enough air to make the downpipes as effective as some hope. They do help with spool like Mr. 5 said but as far as getting another 30 or 40 HP I dont see it happening and raising the boost will not help with this either.

When NYC comes back we will take another look at it and see what we can do, we are more than willing to help him out to make everyone happy

p.s. Shiv should have given you V2 for free....

[NYCGarbagePrince]

Car still needs a bit more work. Just disappointed with the results. I just want to say, there are some guys out there who are making power with exhaust and software. So don't be completely turned off by my comments. We know walkedu is making great power and has been a pioneer when it comes to modding our cars. We saw what 1.47 and Xede puts down with downpipes. It is so similar fighting over 5-10 Hp or tq is splitting hairs. There are others who have put down even more without exhaust at all. At the end of the day the amount of HP or TQ your car makes, doesn't make it any less enjoyable getting in your car and driving it.

has anybody read SHivs response to the lack of actual HP/TQ gain on Walk U's car? he explains the power distribution pretty well, yet people are still stumped.

its in one of the two threads now open on the infamous "335 takes an M5 is this real thread. its one of his replies.

But i'll search.

The difference in performance has more to do with how long that power is available through the RPM band and how spark timing/fuel/boost is managed during dynamic conditions (ie. running up the gears, NOT during a single gear WOT dyno pull). This is where v2 has an advantage over traditional piggy-back contollers. Yes, on the dyno, Walked U's made virtually the same power as our shop car which still had stock dps and stock IC.

So far we've only mapped two fully catless dp'd cars. One a year ago in Florida and Walked U's yesterday. On the dyno, neither had any measurable advantage over cars with stock dps. On the road, however, we might see some benefits. The jury is still out, IMHO. And so far, the sample pool tested is very small so no need to get up in arms yet about their benefits of upgraded downpipes (potential, real, imagined or otherwise.) I look forward to seeing results as more and more cars get these mods.
