News from CHRF
The newest Engine Management ecus from Holley are up and
running on all three Northstar generation engines. The forth gen engine, the VVT
(variable valve timing) has everything we need on the board, but the engineers
at Holley have other priorities right now. Of course these new ecus support
the other engines; LS, SBC, BBC, Ford, and Chrysler.
The HP engine management system has the following features and capabilities;
Ignition plug and play for GM 24X and 58X engines, GM HEI, Ford TFI, magnetic
and Hall effect triggers, including the GEN I Northstar (93-99).
8 channel Distributorless Ignition (DIS) outputs capable of directly driving 8
Smart ignition coils or Holley DIS coils.
Allows one or two, one wire or two wire knock sensors.
1-5 bar MAP sensor capability.
Integrated single channel wide band oxygen sensor built-in. Works with
optional Bosch or NTK sensors.
Eight sequentially driven peak and hold injector drivers capable of driving up
to 16 low or high impedance injectors including multiple staged injector sets.
SELF TUNING capability built-in by setting the air-fuel ratio you want to
achieve. This feature really works well.
Internal data-logging with 2GB memory standard.
Turbo boost control.
4 stage of progressive nitrous control
Integrated water/methanol injection control.
Individual cylinder spark and fuel control.
Configurable for dual cooling fans, dual fuel pumps, AC inputs, basic torque
converter lock-up, multiple timing retard inputs and rev limiters.
User programmable caution and warning outputs for all sensors, water temp,
fuel pressure, oil pressure, etc.
Holleys new gauges are configurable for all sensor outputs; Air/fuel ratio,
fuel pressure, oil pressure, oil temperature, water temperature, voltage, etc.
Did I say this was all standard when you purchase the HP ecu. There are many
more features of this ecu and can be found at [url=http://www.holleyefi.com]www.holleyefi.com[/url].
We build custom harnesses for all applications as standard practice at CHRF.
The DOMINATOR engine management system has the following features and
capabilities of the HP ecu, including;
TRANSMISSION CONTROL, 4L60/80E and T transmissions with more to come in the
Dual channel wide band O2 controls.
Integrated drive-by-wire throttle body control for one or two throttle bodies.
Twelve sequentially driven 8:2 peak and hold injector drivers, capable of
driving up to 24 low or high impedance injectors.
Twelve channel DIS outputs
This ecu does everything all of us could think of. Find out the rest of the
story by logging on to www.holleyefi.com.
We do custom CNC products.
Here's our newest product for the end of 2010, custom CNC water log.
This eliminates the water pump which interferes with your steering column and
brake booster. Both inlet and outlet will be on the passenger's side of
the car. This item will also need your choice of an electric water pump
shown below. $990
We finally received the item we needed to remove the water log from the back of the
Northstar engine. We have worked with Meziere to develop a remote mounted electric
water pump with a thermostat built in. This allows the engine to warm up properly
and run the heater!! We already manufacture a set of cnc plates that mount over the
water inlet and outlet on the rear of the block. Have your hose sizes coming off and
back to the radiator ready when ordering.

Fittings $20 each, specify red, blue or black
1-1/4", 1-1/2", 1-3/4" hose and AN-10, -12, -16, -20, -24
Pumps also come Polished, blue,
or red, anodized, with an up charge.
If you need a custom damper (harmonic balancer), we have 4 different ones
available, manufactured by ATI especially for CHRF. These pictures also
show custom billet pulleys. Call for pricing.
We just finished an adapter for a new cast bellhousing for stick shift
transmissions. You get a new bellhousing, machining
of the bellhousing, adapter plate, flat head bolts and the trans adapter ring.
You need to measure the front shaft housing or register (4.68", 4.858", or
5.125") and give us that number for the correct ring. Pricing is
As you can see, this adapter will rotate 17 degrees for the Chevy T-5 speed
Transmissions that can be used on this bellhousing/adapter:
- Chevy T-5
- Ford T-5
- TKO 5 and 6 speed
- Old Chevy (Muncie) transmissions
We also can provide a hydraulic throw-out bearing.
SORRY - I lost the header guy! So we will continue to have available flanges,
"J" bends, and collectors for your project.
We have an engine mount for the GEN I Northstar ('93-'99) that bolts behind the oil
filter adaptor. This allows the air conditioner compressor to be mounted in the
stock location (driver's side or left side of the engine).
We are currently manufacturing parts for the GM LS
- 90 mm throttle body with the IAC and TPS sensors installed
- Fuel rails manufactured by Aeromotive
- Header flanges
- Complete engine management systems (Holley HP and Dominator) and custom wiring harnesses
- CNC machined aluminum Valve covers
- Blower system is almost ready
You have asked for it, so here are the first pictures of our serpentine belt drives for
the GEN I Northstar. We have since changed the lower alternator bracket to a
stainless steel rod with heim joints. This kit includes the following:
- Alternator, chromed 140 amp output
- Engine front cover plate, aluminum
- Power steering pump, Sweet
- CNC aluminum brackets
- Stainless Steel nuts and bolts
- Custom front pulleys for the alternator and p/s pump.
- Custom idlers, 3 each
- All pieces are polished or chromed
The price for the complete set-up shown above is
We also have a front plate that puts a Sanden 508 compressor on the right
side of the engine.
The new billet aluminum engine mount for the Northstar. They will come
with SS bolts and the center CS mount. You furnish the tube to chassis
connection. $260 or
Also shown to the rear of the engine mount is the cnc remote oil filter plate that fits to the side of the block.
polished plus $15
We have many other products that just hasn't made it to the web site yet.
