This in turn creates the extra hp and torque in the mid range rpms. Just wondering if anyone here has ever used this? __________________ It's always a great day to be underwater and play with the fish.....preserve our oceans and reefs" Fariz 1997 318ti, Hellrot (Bright Red), Dinan Stage 2 Chip 16x7 OEM sport Wheels/X-Brace/Custom Strut Brace/Cold Air Intake/M-Tec Steering Wheel/Koni Adjustable FrontShocks/ Bilstein Sport Rear Shocks /H&R Sport Springs/Custom fabricated strut tower brace/Rear Strut brace, Stromung Exhaust Future Mods: E46 17" wheels or Kosei K-1 17x8.5s | | | 08-20-2006, 03:16 PM | #2 | Senior Member Join Date: Oct 2005 Location: Puerto Rico Posts: 885 | I never read abuot that before, is very interesting... __________________ BMW...MY NEW TOY Mods: Some plastic parts, ///M Wheels and me | | | 08-20-2006, 06:13 PM | #3 | Senior Member Join Date: Dec 2005 Location: Asheville NC Posts: 669 | it's a popular thing to do on the jeep wrangler message board that I lurk on. I'm skeptical but was planning on making one for my jeep one day just to test it out, is there benefit for our cars too? I could probably get some made on the cheap if so. | | | 08-21-2006, 07:03 AM | #4 | Senior Member Join Date: Mar 2005 Location: Portland Or Posts: 2,666 | I have one on my Jeep wrangler. It moves the power curve DOWN, it does not add HP. I have a fairly modded motor, I bumped to a bigger throttle body and wow it woke up but my bottom end torque dropped. The spacer brought that back in line. So if you need more low end at the expense of top end rev's it helps a lot.

I've been looking into getting one, but haven't had too much luck finding any. | | | 03-31-2009, 04:08 PM | #6 | Senior Member Join Date: Aug 2004 Location: state college, pa Posts: 3,431 | Longer intake = torque. Short intake = hp. It's not a matter of making more power, it's about moving that power around (the powerband). __________________ I scream, you scream, we all scream for ZOMBIES. | | | 04-18-2009, 09:46 AM | #7 | Senior Member Join Date: Mar 2005 Location: Portland Or Posts: 2,666 | All it is is a plate that matches the bottom of the throttle body. The one on my jeep is about 1" thick. I doubt it would help a TI we already have a 2 length intake manifold. Its way more likely to get the power if we could controll the secondary throttle valve adjustably...

BMW engineers aren't stupid, they thought if this stuff already At low rpms the intake runner is shortened, at higher rpm it becomes longer. A TB spacers will not net you any gains, might just cool off your upper intake manifold a bit, nothing really worth making or buying one. And EuroJDMHB: we already have headers from the factory, not manifolds like the 6cyl motors. the M42 has the best flowing factory header I think I have ever seen, an aftermarket one will give you no power. You might see a few hp with a catback though. Nothing that really justifies the price unless you do something that adds a significant amount of power. __________________ -Jeff | | | 06-05-2009, 12:00 AM | #10 | Senior Member Join Date: May 2009 Location: Orange County, CA Posts: 2,019 | Quote: Originally Posted by Xenocide From taking my motor apart it looks like we already have a variable intake runner that is vacuum assisted just for this reason.

I have been reading a lot about boosting the m44 and have been talking with my tech, and he said its a lil iffy but we can do it. I was thinking about runnin only a SMALL amount of boost about atleast 8-12psi . | | | 06-05-2009, 03:35 AM | #11 | Senior Member Join Date: Aug 2008 Location: Raleigh/Charlotte, NC Posts: 1,233 | small amount of boost? I'd be surprised if your head gasket held 12psi for more than a few thousand miles A small amount of boost is 6-8psi. Your planning on "boosting" this car...they don't sell supercharger kits anymore, only thing you could easily do is a turbo, and you cannot put "headers" on a turbo car. you need to do your research bud __________________ -Jeff | | | 06-05-2009, 03:49 AM | #12 | Senior Member Join Date: Sep 2007 Location: asdfasdf Posts: 10,002 | Quote: Originally Posted by Xenocide Your planning on "boosting" this car...they don't sell supercharger kits anymore, only thing you could easily do is a turbo, and you cannot put "headers" on a turbo car. you need to do your research bud | he never said he was going to use a turbo, and you can still buy DASCs, you just have to get them used | | | 06-05-2009, 08:20 PM | #13 | Senior Member Join Date: May 2009 Location: Orange County, CA Posts: 2,019 | Quote: Originally Posted by Xenocide small amount of boost?

Also even if i double the head gaskets it still won't hold the proper amout of boost i am trying to achieve? i was just thinking of running about 6psi for the start then atleast get up to 10-12 psi, nothing higher or else no more m44 hah. yes i am going to run the m44 no s52 or s50 swap for me. | | | | 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 | | | |
