Before this car AJ133 got finished up, we put on our custom 10 rib pulley setup on it.

As far as I know, I’m still the only one with a full 10 rib setup. This ratio is a bit extreme, but I have many different ratios available. At the limiter this specific setup spins the TVS1900 up to 24000 rpm.

All designed and made in the US.

Another XKR in the shop is getting fitted with the same setup this week! 🙂

These Sparco SPX seats are 28lbs entirely built up. Stock seats were 70lbs.

80lbs in seats is quite a lot, especially on these heavy cars.

Hoping in the future we can get more data on weight with these cars.

700hp corn fed jags are pretty wild.

Some days I swear all I do is eat, sleep, and breathe Jaguar. It’s been high time I start sharing my successes and failures with the world!

Rebuilding two AJ133 engines side by side is no easy feat, but it was pretty fun.

Did a tune up and replaced a control arm on a 2006 Monte Carlo. Control arm was bent and it was time for fluids and spark plugs. Also cleaned up the engine bay a little!

You need a custom box? Or custom anything from wood? We can do it! We can do everything from Octo ports, boxes, pods, you name it! Some things are CNC cut - we are currently upgrading our CNC so all our boxes will be cnc cut soon!

We start by designing everything on CAD to provide you with the most accurate box possible. We then have them precision cut to bring your beautiful box to life. Message for pricing!
