E-Torque offers cam blanks for those who wish to design their own cam profiles. These cam blanks will support a lift of up to .500”.

These camshaft blanks are sold in pairs for Intake and Exhaust.

Although E-Torque cylinder heads have seven cam bearings, these can be used with standard Jaguar cylinder heads that have only four cam bearings.

The Street Performance cam profile was designed to impress the driving enthusiast. It has a semi-smooth idle quality at ~800 RPM with decent low end drivability. As you get on it, the cams produce building power that is strong through the mid range. These street camshafts continue to pull to 5800 before tailing off. Whatever they lack at low speed, they more than make up for at the top end.

These street camshafts do not work well with SU carbs, as they demand strong vacuum at idle and low speed. The Street Performance automotive camshaft profiles do not provide more than 10 inches of vacuum at an idle and this is not ideal for the SU HD8 carburetor.

Weber carbs can be tuned to deal with the low vacuum condition - although EFI would be ideal. The drivability will improve with Fuel Injection removing any downside and enhancing the high end performance.

Even though E-Torque camshafts have three extra cam bearings, they can be used on standard Jaguar XK cylinder heads.

Specifications:

Intake Lift = .466”@ .050” Duration = 258°

Exhaust Lift = 426”@ .050” Duration = 258°

The Mild Performance car engine camshaft profile was designed to work well with SU carbs, as they demand strong vacuum at idle and low speed. The Street Performance cam profiles do not provide more than 10 inches of vacuum at an idle and this is not ideal for the SU HD8 carburetor.

This grind is aimed at drivability rather than peak power. It will give you a fantastic idle quality and give torque right off an idle for a crisp off-the-line thrilling ride. It will have a robust mid-range pull and then gently begin to moderate above 5000 RPM. This is the car engine camshaft chosen by Eagle Works for their production cars after they performed extensive testing.

Even though E-Torque camshafts have three extra cam bearings, they can be used on standard Jaguar XK cylinder heads.

Specifications:

Intake Lift = .421”@ .050” Duration = 244°

Exhaust Lift = 391”@ .050” Duration = 240°

The E-Torque Cylinder Head has three more cam bearings than the original Jaguar XK cylinder head had. Although the E-Torque Cylinder Head can use the original Jaguar cam covers, some of us like the look of all those pretty, chrome acorn nuts arrayed across the shiny aluminum surface of the cam covers. This difference let’s people who know the XK engine, that this one is something very special.

The E-Torque Cam Covers differ from the Jaguar parts in one feature. On the original Jaguar engine, the oil fill was on the exhaust (left hand) side of the engine in the front. This is for two reasons. First - the XK engine was first used in Jaguar cars that had a hood that opened from the front. The fullest access to the engine was therefore at the front. Second - Brits drive on the right side of the vehicle, so if you were pulled off to the side of a road, they wanted you to be filling from the left side of the car - which is away from the highway traffic. We put the oil fill cap on the back of the valve cover because E-types have a bonnet that hinges from the front, so the access to the engine is from the back side. We moved the oil fill to the intake side of the car so that drops of spilled oil do not land on the hot exhaust manifolds.

The E-Torque Series I Cam Covers are an exact replica of the original Jaguar parts with three sets of holes for the additional studs to pas through. These engine cylinder head covers are cast in plaster to resemble the fine detail of the original Jaguar parts and polished to a mirror finish. The engine cam covers come with a brand new polished oil fill cap that is oriented properly to the cover and a Cometic cam cover gasket set.

This stroker kit for sale will increase a 3.8 Litre Jaguar XK engine to 4.1 Liters. This is done by increasing the offset on the crankshaft from the original 106mm to 115mm.

These cranks are made from billet steel and are much stronger than the original cast steel cranks. The original Jaguar crankshaft was no fully counter-weighted. The E-Torque Stroker Crankshaft is.

We have designed these cranks or stroker parts to use the Chevy Clevite rod bearing. That makes the rod narrower and reduces reciprocating weight in the rod and the crank journal.

This custom made flywheel is engineered to provide a reliable pulse signal to your ECU or Twin Spark Ignition System. This Kit includes the flywheel, the pressure plate, friction disk, a custom roller release bearing and sensor bracket.

Triggering from a distributor is a bit dicey because it is driven by a gear and pinion shaft. In any gear system, there is backlash, which provides a bit of slop so the gears don’t bind. The problem with this kind of drive is that the lash is drifting back and forth as the engine revs and decelerates. So, your timing does the same thing.

Crankshaft triggering is much more precise because the triggering teeth are bolted directly to the crankshaft so there is no variation in the spark timing.

The first crankshaft trigger systems put the trigger teeth on the perimeter of the flywheel. Those were obsoleted because the dust from the clutch disk would make the sensors false trigger. E-Torque has however designed its trigger teeth on the front side of the flywheel to prevent dust from interfering with the signal. This system works very well and is desirable with Twin Spark Ignition or EFI systems because they benefit from the accuracy the crankshaft trigger offers.

These flywheels have a removable ring gear that can be changed from time-to-time as the starter teeth wear on it. It is balanced with the ring gear installed.

The flywheel is designed to the original Jaguar weight of 24.5#. Lightweight flywheels are ok for racing but not for street applications - no matter what someone tells you. This is more of an issue as the cams get hotter and the low-end drivability suffers from excessive overlap and resulting low vacuum. Cars can shutter as they start from a stopped position because there isn’t sufficient “flywheel effect” to overcome the misfiring with hot cams at low RPM.

We pre-drill the flywheel to accept a Advanced Clutch Technology (ACT) clutch package (F013). These are made by the thousands because they are fitted to the Ford 5.0L V6 engine. The clutch is very high quality for a very affordable price and rated for 425 lb/ft torque.

All E-Torque exhaust systems have optional Catalytic Converters (or “CATS” as they are called) available. They are integral to a link pipe that connects a down pipe or header collector to the inlet of the silencer. This catalytic converter kit is designed to fit 4.1 - 4.8L engines with 2.250” link pipes.

Recent dyno testing conducted in the UK revealed that, at 70 MPH, a pair of Catalytic Converters (CATS) cost roughly 5 hp and 7 lb/ft torque over link tubes without Cats - (see report on “Results” page). They however provided a reduction in Hydrocarbon (HC) of 94%, Carbon Monoxide (CO) 26%, Carbon Dioxide (CO2) 4%, and best of all, a reduction of 42% in Nitrogen Oxide (NOx), which is linked to respiratory disease in cities.

Given these profound benefits, and the current threats to our environment, such a minuscule loss of power is an inconsequential price to pay for such a substantial decrease in emissions.

The Air Filter Element in all E-Torque Pre-Induction systems is custom made for E-Torque. Although it looks similar to K&N style air filters, this XK air filter element replacement is not a standard product and does not cross-reference to any other vehicle.

Before replacing your Air Filter Element, you might want to wash it with soap and water according to the manufacturer’s recommendations. Go to greenfilter.com for this information.
