ITB's Anyone ?
 
Hey guys,

I've been developing a new product and wanted to share. I'll be debuting them at my booth at the GAF next week in Ventura. I just thought my fellow Pelicanites might want a sneek peak. Cheers!

Are you ready to post specs? If you are, please. If not I will see you at GAF.

I'll see you at GAF anyway!SmileWavy

These ones have 48mm butterflies tappered down to 40mm ports. The trumpets are also CNC tappered, all the shafts are ball bearing supported, etc. The air cleaner is integrated as well as TPS provisions. I haven't really put together a comprehensive spec list yet, hope to have it by the show.

nice! pricing and availability?

Jeff Alton 08-31-2007 04:49 PM

What are you using for linkage? Have you thought about moving the injector up a little in the manifold?

Cheers

mb911 08-31-2007 05:31 PM

I am thinking they would be fun for turbo application as well

berettafan 08-31-2007 05:36 PM

i vote 'ban' if no specs or pricing info is posted within 48 hrs!!!

ChrisBennet 08-31-2007 07:14 PM

Mark you are such a tease!

They look great!

They have a definete grace to them that is for sure, look very nicely finished! Any shots of the throttle plates?

cheers

Ben, great minds think alike :D
Mark, those are beautiful!
By the way, what happened with your semi-auto transmission project?

Natchamp 08-31-2007 07:47 PM

Thanks guys,

turbo version ? definitely in the works. I want a set for my car!

linkage? I have a couple draft designs, haven’t decided which one yet.

availability? Imminent

high injectors? Maybe an option if there is enough demand

pricing? Less than TWM’s but much better quality

Natchamp 08-31-2007 07:52 PM

Jeff, here is a shot from the top. It didn't turn out very good because of all the flash wash. They really do look much better in person.

Those are very nice. I am interested to hear more.

Jeff Alton 08-31-2007 08:26 PM

Mark, those look great!! Lesst than a set of TWM's?? I have Jenveys's right now but will retrofit and give you dyno results if you want!

Are the fuel rails -6AN?

Cheers

Natchamp 09-01-2007 10:59 AM

Yes, less than TWM's and keep in mind these are not cast. everything is machined, the throttle bodies and even the trumpets are all 100% CNC'd.

Here's another design aspect that I am proud of. The trumpets are extreemly easy to change. They actually screw into the base plate. So, different legths can easily be adapted for different applications. For example, a racer might want a shorter stack for a high-end track like Willow and a longer stack for a grunt track like Sears Point.

I am assuming you can make them for different intake port sizes for the various heads as well?

Very nice idea with the trumpets!

Cheers

Ok as im about 2 weeks away from buying set of TWM's this thread couldnt have come at a better time, and hence I have some questions. I know high butterlies are good for high RPM race engines but what about street motors? will driveability be poor with the high butterflies? Will high butterflies cause any issues using a MAP sensor based FI system? and do these intakes come with vacume ports for such sensors?

Thanks Steve

Natchamp 09-02-2007 04:28 PM

Hi Steve,

These will work great for the street and driveability would be excellent along with throttle response. They do have vacume ports (below the butterflies) for MAP sensors. Each throttle body has a port so you can gang them to even out the signal. What ecu are you planning on running? Most NA systems are TPS based while MAP based are usually used on forced inducted motors.
