Join Date: Aug 2004 Location: Denver, CO Posts: 3,925 | for those with engine swap: m50 manifold before and after dynos Just thought I'd post this for those with s52/m52 swaps. This does not apply to 318ti's without a motor swap. m50 manifold before and after dynos Cars: 1999 BMW m3 5-speed 92k miles Mods: Dinan Euro MAF Dinan Big Bore TB Dinan Carbon Fiber Intake Dinan Free flow exhaust Dinan Stage 3 software I used a manifold from a '95 m3 and Eric's kit (m50manifold.com). Eric's kit works VERY well. His instructions and pictures make it an easy install. Total install time was about 6 hours, I took my time. I was imediately impressed with the new power. With my snow tires (235/45/17 Dunlop Wintersport D3s) the tires would spin at anything more than 1/2 throttle in 1st AND 2nd gear. That's kinda fun. Dyno runs were done 3 days apart, temperature was between 50-60 degrees in the dyno room. The dyno is a 2WD 450DS at Performance Engine in Madison, Wisconsin. Baseline dyno results: These are uncorrected, so they look a little low. After the m50 manifold installation: The result is a 22 hp max hp gain. There is the expected small torque lose, but as you can see on the graph, max torque is almost the same, it just hits later in the rev range. The red line on the graph is the pre-manifold install, the teal and purple lines are two post-manifold install runs. Here is the corrected version, 13% correction added: Manifold runner size comparision: I didn't get a print out of the AFR, but it gets pig rich around 4500 rpms. My guess is that Dinan runs a conservative rich tune. I think it's time for cams and new software now. __________________ '99 Dinan M3 | | | 01-28-2008, 06:42 AM | #2 | Senior Member Join Date: Jun 2003 Location: Saint Paul, MN Posts: 3,244 | Thanks for the info Dustin. What's the 13% correction for? Wheel hp vs. crank? __________________ My Former Rides 1999 318ti Alpine White, Cali Roof, Dinan goodies 1996 318ti Hellrot California Edition | | | 01-28-2008, 03:00 PM | #3 | doesn't care about you.

Wheel hp vs. crank? | Dyno Dynamics read 13% lower than most other dynos. A 13% correction factor is always applied to a DD graph to make it comparable. The max numbers are really irrelevant, it's the net gain that I wanted to document. 22hp gain for $300, that's huge. 230x1.17 (drivetrain lose) = 269.1 crank hp. That should be spot on given the mods the car has. Cams and AA software is next. Hoping to get closer to 250-260 at the wheels. __________________ '99 Dinan M3 | | | 01-28-2008, 04:07 PM | #4 | Senior Member Join Date: Oct 2007 Location: Eugene Oregon Posts: 6,182 | very nice! __________________ -Josh Sold-1995 318ti, Club Sport, Hellrot Sold-1996 318ti, Active Model, Boston Green Current- 1995 318ti, sport model, schwartz | | | 01-29-2008, 04:51 AM | #5 | Moderator Join Date: Mar 2007 Location: Maryland Posts: 3,220 | I can't wait to swap, wait a minute, I've been waiting for years! | | | 01-29-2008, 02:53 PM | #6 | Senior Member Join Date: Mar 2007 Location: OKC, Oklahoma Posts: 387 | Damn I need one if these!! like really!! | | | 01-29-2008, 03:00 PM | #7 | Senior Member Join Date: Jun 2003 Location: Saint Paul, MN Posts: 3,244 | I wonder what kind of gain you'd see on an M52. This requires no new software right? Did you have to drive a 100 miles for the computer to adjust or anything? I've heard it takes that long for it to reach max power/smoothness, etc. Edit: just realized you had the Dinan software already. __________________ My Former Rides 1999 318ti Alpine White, Cali Roof, Dinan goodies 1996 318ti Hellrot California Edition | | | 01-29-2008, 03:26 PM | #8 | doesn't care about you.

I'm going to hunt down a set of cams and switch over to AA software sometime in the future. __________________ '99 Dinan M3 | | | 12-29-2011, 01:45 PM | #9 | Member Join Date: Sep 2011 Location: Toronto/Munich Posts: 83 | ^ Hey, I know this thread is a bit old, but like most forums I imagined its prefered here when you search as opposed to posting a new thread on the same topic. I found this info. very pertinent to something I'm doing right now. I have a euro 323Ti with the M52 motor, and have a seperate, uninstalled, ECU (correct for my car - from a friend) with Dinan stg. 3 software loaded on it and the opportunity to pick up the M50 manifold with swap kit at the moment. At first what I wondered was whether the Dinan software would help with the adjustment to the M50 and the torque loss you hear so much about? The software is for intake, exhaust, ect. ect. but Dinan doesn't anything about Manifolds. Second, I wondered if it was better to just get a custom tune for the car as opposed to using the Dinan stage 3 ecu for the setup? Any thoughts? Did you feel the Dinan stage 3 underperformed for your needs? i.e. too mild or reserved of a tune or not specific enough to address or get the best out of the M50 manifold?? T.I.A.

If money permits that is. And with the larger maf and injectors, you'd need a new tune to support it, but you would get some large-r gains __________________ Im guessing im the youngest member on here with a S52 power'ed Ti at 16 years old! | | | 12-29-2011, 07:33 PM | #11 | Member Join Date: Sep 2011 Location: Toronto/Munich Posts: 83 | ^ Hi, thanks for the suggestion, but at the moment I think I am just going to go with what is available to me and within my means presently i.e. Dinan CF intake, M50 Mani, and tune. | | | 12-29-2011, 07:38 PM | #12 | Senior Member Join Date: Nov 2010 Location: Potomac Falls VA DMV Posts: 1,794 | You should be perfectly fine then __________________ Im guessing im the youngest member on here with a S52 power'ed Ti at 16 years old! | | | 05-22-2012, 08:19 PM | #13 | Senior Member Join Date: Jun 2003 Location: Greenville, SC Posts: 9,356 | Quote: Originally Posted by slow_ti If I were you, I'd get the M50 manifold, Samco 3.5 inch silicone intake boot, 3.5 inch maf and intake, and larger injectors.

Is it worth doing the M50 manifold alone? __________________ ...steven BMW CCA #146825 1996 BMW 328ti • 2003 MINI Cooper S • 2016 M235i www.bmwcca.org | | | 05-22-2012, 09:50 PM | #14 | Junior Member Join Date: Jan 2009 Location: Charlotte Posts: 28 | On my M52 328i and on a Dyno Dynamics dyno I gained 7hp and 1tq from just the M50 manifold. With the samco boot, stock maf, afe intake, and TRM tune. I made an additional 12hp and 5tq. I'll have to dig out the graphs and scan them to post. Might get to that tomorrow, if someone wants them. | | | 05-22-2012, 11:48 PM | #15 | Senior Member Join Date: Jun 2003 Location: Greenville, SC Posts: 9,356 | Quote: Originally Posted by 1slowcrx On my M52 328i and on a Dyno Dynamics dyno I gained 7hp and 1tq from just the M50 manifold.

I track out at 85 mph (indicated) and at the end of the straight I'm doing around 120 (indicated). Ambient air temp in the 80s. It takes me a while to get up to 120. I'd like to get up to speed a bit quicker to carry it longer. __________________ ...steven BMW CCA #146825 1996 BMW 328ti • 2003 MINI Cooper S • 2016 M235i www.bmwcca.org | | | | | Currently Active Users Viewing This Thread: 1 (0 members and 1 guests) | | Posting Rules | You may not post new threads You may not post replies You may not post attachments You may not edit your posts HTML code is Off | | | |
