Stock 12t turbo lb min


Welditup

Recommended Posts

Just an update. I did some logging with a scanner and I'm getting 20.5 lb/min of flow outta the stock 12t at stock boost in first gear and then tapering to around 19 lb/min at the end of 2nd gear(80mph) and sometimes hitting 18.2-18.5 lb/min at the end of third gear(115mph). I hit 20.5 when the temps dipped down to the low 60's f. Does everything look good? I'll get a better log(engine temp,intake temp,O2 readings, timing, and lb/min) in as soon as the weather clears up and I'll have base readings for a near stock s40 with just exhaust and intake mods at stock boost. I'm going to keep track of all my readings as the mods increase to share with everyone. Seems like there's never enough information for our s40's out there,lol. So far she's loving it, no CELs and gas mileage has suffered due to my foot, opps. :)

Different measures.    

 

PSI is a measure of pressure.  lb/min is a measure of mass flow.  

 

To really dive into any increases you need to calculate VE.  volumetric efficiency.

That makes a lot of sense. Thanks for the clarification. I watched the videos you posted a while back. It seems like you've put in a lot of work on it. Updated pictures of under the hood? I thought I saw you start a thread on another site where you were planning on outlining the work you were doing on it. I'd be interested in that type of thing.

I did have an 01' S40 that was built up pretty well.  Koni/Eibach suspension,  enkei wheels, turbo-ic hard pipes, 14T turbo,  upsolute dyno tune, manual boost controller,  ran around 18-20psi and made 250hp and 300ftlbs when all said and done. 

 

I now daily drive my S60T5 and the fiance drives the V40.  

 

V40 i'm keeping relatively stock, all tuning has been done with a wideband aem uego that i can trade off between the vehicles.  Added a bung for the O2 sensor and a quick connect for the boost gauge so I can tinker and tune and them remove all the gauges and she never knows, lol. 

 

Right now the exhaust is unmolested.  Running stock 12T turbo,  all turbo piping and radiator hoses have been replaced with DO88 hoses.  The exhaust cam on the vvt took a dump so i opted to have the cam gear locked in full advance,  which hinders economy,  but gives the cams more lift across the full powerband.  Running a K&N panel filter and upgraded to 420cc injectors from an 01'.  It is lowered a bit,  but still on stock 15" wheels and I +1'd the tires from 195/60/15 to 205/55/15.  Also Kristian at SNABB fabricated some spacers so i installed one on my manifold and throttle body.

 

Next on the list,  i have a K&N apollo that i'll be installing in place of the factory panel air filter setup,  as well as a large bore throttle body that i'll have done through an exchange service.  Also have some poly mounts waiting to replace the lower engine mountings when they finally go.

Well I should have all the info tonight. I got a 2 hour commute tonight to check out a fabrication job on a bridge in Taxachusetts so the scanner coming for the ride,lol. I'm curious to see the timing more than anything.

hello, ive had my 04 v40 1.9t for about a year now and am ready to start modding it for speed. i just put in a boost controller today and thought it made a big difference. running 10.5 lbs. i had it at 14 but there was a plastic burning smell after driving the car hard, so i reverted back to 10.5. any suggestions on speed mods appreciated, aswell as what boost the turbo and engine can handle with the stock turbo.

It should be ok at the higher psi I think but I think you were smart to turn it down when u smelled burning rubber. Have you done a full stage 0? I just started here recently but doing a stage zero will not only result in a more powerful car usually but make it safer and more reliable to add power. Based off the burning smell it sounds like your hoses might be a good place to start by going to silicon or stainless steel. Here is a good article for stage zero

Yeah. I think you are tight about the hoses. I checked them earlier and they were hot where they connected to the boost controller, which is made of brass. Any idea where I can get the hoses from without over paying on ipd? Hardware store? I have checked out the stage 0 and I have guessed it will cost about 200? Maybe around there? I'm going to order the red fuel injectors soon as long as they're not extremely difficult to install.how much does the stage 0 help? Gain much hp from it?

Did 2nd gear into 3rd pulls. I drove her for almost 30min between two runs on the closed course before I romped on it so my intercooler wasn't heat soaked.

-fuel- shell 93 octane (ethanol blend) 

-engine temp- 187 F

-Advance timing was around 22.0-22.5 at WOT

-lb/min held a steady 20.1-18.7 (roughly), the flow was falling off fast after 6k rpm.

-intake temps were at 85-87 F (ambiant was 75 F low humidity)

-stock boost

- The only thing I got left on my stage zero is a tranny flush. 

I'm pumped to see what she'll do with a MBC and my cat-delete with the logs and 1/4 mile difference.

Another trick to keep those IAT's down (which should help with the timing pull).  You can bypass the coolant line that connects to the pcv system.  Basically run it straight from the thermostat housing to the pcv system and don't loop it around the intake.  Will effectively lower IAT's about 25*F
