I'm wondering if anyone has experience with the intake kit offered by v12s.com. Page is here. It's less expensive than the faster jags growler, of which I've heard good things.

I've emailed v12s.com but haven't received a response yet. Thanks in advance!

 

made at home in garage,, 78 xjs roadster.

K&N filters, 3" pipe bends, 90*

works great sounds cool!!

 

Looking good! Unfortunately I lack the skill to fabricate the components myself, so I'm looking at bolt-in replacements. Have you done a full writeup on your mods?

 

Since *cold* air is even better here are a few ideas. Nothing pre-fab, though

doug if you notice my air inlets could be easily made to go forward for cold air!

but on a chassis dyno we made tests, with air filters off and a large overhaed fan blowin cold air down with hood open, engine made 3hp more , hardly worth effort for more mods ,
but like i said could be modded easily!

 

and i never did like the way factory filter system works,air flow disruption, just to tight for smooth flow, IMO!

 

Just out of curiosity, what did the dyno show for your intake system, as it stands, versus the stock system?

sorry!Doug no tests done with factory filters.
i only tested with hood closed with K&Ns, and hood open no air filters.

but that factory filter test would be interesting!

they just look constricting to me!! to many corners and air flow direction changes.

best air flow is straight line of site.

 

and knowing what i have learned, i would make custom sheet metal inlet PLENUMS with TBs at the front, straight in!

I've been experimenting on a my other XJS project and grafted the intake from a 6L v12 with intakes from AJ6 & K&N filters.
Now it's taking in more air than the ECU can figure out so I have to either modify the ECU or try one off the 6L.
The thing that does work better is removing the second catalytic off the exhaust, stainless pipes from main catalytic going back to muffler. There's just a bit less back pressure and more willing to run.

All of the above plus a tune, your car will thank you.

YUP,, a little loud, but 12 cylinders at 7000rpm. WOW

 

Nice one!
Is the top custom chopped? There were no roadsters in 78
Like your lamp & front end mods.

& RPM ,oppsss 7000 RPM ? That's a powerful engine then I give a credit for it

 

How about these?

THANKS Cadillac, and the guys!
it is a head turner at shows and street cruisin, and NO it aint no race car, but some of those Corvettes have seen its tail lights!! LOL.

 

HI, Cowboy,and sean B, i did the roadster conversion myself, but it came over from England as a Cabriolet,(supposedly by AMT), notice its RHD.

it is a garage queen more than a daily driver. i take it out for fun and crusing,dinner engagments etc. weather permiting.

Looks great Ron!
Happy cruising
