pic of 12 ITBs on a jag V12, rare,to say the least!

never came on a factory V12 car!

these were cast from magnisium,not aluminum,(lighter weight), and tapered trumpets. they have a slide throttle plate, not rotate butterfly type!

grp 44 racing mid 1980s, sometimes show up on Ebay.

 

someone said you cant slide big rubber, pic of 295-35-18 KDWs.

 

That's awesome.

I've actually made a slide type throttle body for a 13B from machined aluminum from the housing & a machined PTFE plate for the slide.

It worked pretty well, until boost hit above 5psi, then it would stick due to thrust loading.

So I went back to the OEM throttle body design.

 

Well.

Body & paint start tonight, after work.

Should take a couple days to get it ready for primer, then another few days to get it ready for paint.

 

true about slide throttles and boost pressure,

seems lately that barrel valve type throttles are in favor, on hi-tech turbo engines.

of course DI(direct injection) is the ultimate method at getting fuel into the chamber!

 

The trust load issue could be managed by inserting the PTFE slide into a plate that sits on roller bearings.

 

P.S. sanding is almost completed, should be done today.

High build primer tomorrow & more sanding!

 

 

my 78 roadster weighs in at 3360lbs 1/2 tank fuel, no driver.

mind you its a V12 engine!

 

Paint is complete.

Going to be fabricating the hydraulic e-brake & hopefully we can get some track time this coming Monday.

 

Let's see some pics and videos of this beast already!

 

We will be releasing all details & media @ the beginning of September.

 

September is shaping up to be an exciting time in auto circles: Jaguar XE, new Miata, and the big reveal from THIS THREAD!!!

So...thats you car?

 

That looks cool! But enough with the hype – let's see real photos and story, already.

 

I'm calling BS on this one.

 

No it's not my car, it belongs to my boss.

We built this car durring the Spring months & have been testing/ tuning it throughout the Summer months.

I work @ Xcessive Manufacturing, where we design & build race application components for cars (we do other stuff as well)

I'll keep posting stuff as it pops up on my social media feed (this pucture was from the Sunday/ Monday PARCFEST event in Canby Oregon @ Pat's Acres Race Complex.

Car is being piloted in this picture by driver Justin Lucas

Everything on this car was built/ modified in house @ Xcessive Manufacturing.

 

Tar, come down. The shop & see it for yourself.

You're local to Portland, Oregon & so are we.

 

I'll accept your apology later, I'm too busy dealing with messages from people that were at the event.
