Just a note?
It's a TVS1900. Twin Vortices Series Supercharger.
Same one is used on the Cadillac CTS-V.
Here is a good bit about the blower from Eaton who makes it.

Well if cambo can recomend where or send link wheren to get the best tune will be glad.]]]

BUT i did make progress today, I changed the complete belt tensioner, JAGUAR seems to have a upgarde, which puts the pulleys in diferent locations, so it ends up being far from the water pipes, like 2 INCH clearance, instead of 1/5 inch lol.

it came with plastic pulleys, and groved including the tensioner one, I ALSO DIT alligmnet of pulleys , with some light sheem washers from behind, so the belt runs straignt, NOW belt runing without any movment or slip, or squuel.

I NOW HAVE NO LOSS OF BOOST< AS SOON as I HIT THE THROTLE DOWN IT INSTANTLY I HAVE INSTANT 8 PSI, from there it JUST steadily goes up to around 11.5PSI, at over 140MPH to around 12.5PSI at 6250RPM>

SO THAT MEANS NO OVER SPEED ON THE CHARGER, AS THE BOOST JUST CLIMBS WITH RPM!!!!!! AND ALSO NO slipage of belt, BEFORE i would get to 9 PSI, at around 4000rpm, and then start loosing pressure as low as 5 PSI on 6250 RPM<
I did find lots of fine shreded dust from the belt around the pulleys, engine bay etc.

BUT no more, holding fine for now, .... even when hot, I NEED a COOLER THERMOSTAT, anyone KNOW where to get one THAT OPENS AT LOVER TEMP, THE engine BAY gets DAM HOT when the CAR PUSHED to the limit... LOL

 

Dont seem to be abble to post pictures>????

 

Any idea why??

 

what tune are you running

 

I am running Qauntum Tune,

I can post the details,

I have reconstructed THE RIGHT side of my EXHAUST, !! went testing, and until 2000 rpm, car is silent, so can be driven normaly ,, in town, on express at 80-100mPH, its silent when under 2800RPM, and not presing the Throtle much,

But WHEN you hit the Throtle HARD, !!!! the CAR is an animal, and NOW sounds like one, DEEP , RUMBLE, ..

I INSTALED MAGNA FLOW REAR ENDS< AND REBUILD THE CENTER X PIPE< I HAVE KEPT ORIGINAL CATS FOR NOW>>>

as seems the main restriction in the Exhaust was the rear END,

 

OK< so went racing again,

well, what can I say, need to look into TUNE, and TYRES

thinking of

TOYO PROXES R888R 315/30R20 101Y

any coments will be apprecitaed

also what TUNES OUT THERE ARE GOOD< and are doable long distance

 

Tires: factory 285/30/20 is about 26.73'' tall. my calculation is new proposed 315/30 would be 27.44'' tall and obviously 30mm wider tread.. might rub. might need to invest in fender roller tool.
Tune: Velocity AP is pretty responsive and their tune can be shipped via device that plugs into obd2 port.
