As you may already know, it's easy for oil temps to skyrocket on the LT4 platform on the street and at the race track with many seeing oil temps at or near 300F, which can be an engine killer. One issue with the OEM oil cooler was the decision to cool the oil using your engine coolant. This is not only ineffective on hard track days, but it should be obvious that 250°F + coolant and the 250°F + engine oil will essentially heat each other as things get spicier and spicier.
The solution? The GMS remote oil cooling package + High Flow Impact Bar Bundle. This is the best oil cooler solution on the market for your LT platform.
STAGE.I Oil Cooler Kit Includes:
- GMS High Flow Impact Bar Assembly (optional)
- Improved Racing Block Off Plate (with hardware)
- CSF Dual Pass Oil Cooler (with -10AN male fittings)
- Raceflux -10 AN Fittings & braided hose (cut to length)
- GMS OEM Oil Cooler Delete fittings (Silicone + Billet Cap)
- GMS Brackets to mount direct to the OEM Crash Bar (optional)
- (2) 12" lengths of 2,000F Thermal Wrap to protect from headers
- Improved Racing High Flow In-line Thermostat + Bracket (optional)
Product Details
Design & Engineering
There are many factors that make the GMS kit the best oil cooler on the market for your LT platform.
Separating/Divorcing the Coolant and Oil Systems
To start, GMS separates the oil and coolant by removing the OEM oil cooler all together, and replacing the undersized OEM unit with a large CSF #8066 22" x 5" x 2.5" dual pass, bar plate unit. It includes built in -10AN male fittings and a classy matte black heat rejecting finish that coordinates perfectly with the GMS High Flow Impact Bar.
In fact, this ultra-effective cooler hides perfectly behind the upper portion of the grill and flow-tie thanks to a custom bracket which puts it out of view.
From there, the next big consideration is oil delivery. With your OEM cooler out of the way, we can now install the Improved Racing block of plate. This unit is not only absolutely gorgeous, but it fits perfectly, and includes the -10AN bosses that you need to run proper AN lines and fittings.
Thermostat and Temperature Control
The next consideration is temperature control. The GMS solution is another Improved Racing piece of art, by way of their High Flow inline thermostat. The beauty of this unit lies in its ability to allow a very small amount of oil to pass through when closed, which helps bring the stored oil within the cooler to a similar temperature, preventing cold oil from shocking the system when the thermostat opens. The GMS kit includes a 185F thermostat.
AN Lines & Fittings
Bringing it all together is a pair of braided -10AN hose and all of the AN fittings you will need for a super clean and efficient system. GMS also provides you with a high quality block off kit that allows you to remove all of the OEM oil cooler lines for a cleaner look, by installing one 5/8" hose cap and one 5/8" anodized aluminum quick lock cap.
HP Rating
Based on the size and location of this #8066 bar and plate cooler, GMS recommends this option for street cars up to 1,000hp and track cars up to 750hp.
Oil Pressure
On the GMS 1,000hp test car with a Katech oil pump, they saw no change in oil pressure before and after the oil cooler installation. Hot idle before and after ranges from 31.5 - 33.5psi. 6000k + RPM at WOT ranges from 60 - 75psi depending on the gear you are in. No change after the cooler was installed. Note, GMS did change from 0-40W oil to 5-50W oil for street use, and recommends 15w-50 for track use.
Value
The goal was to not only provide you with the best turn-key oil cooling system on the market, but to save you over $450 on parts when purchased as a bundle. GMS and CSF are confident that you will love the design, fitment, attention to detail and performance of this Stage.I oil cooling package.
New Mounting Option Available
For those who wish to mount this solution to the OEM crash bar vs. installing the GMS signature high flow crash bar, GMS now offers a pair of custom laser cut steel brackets with a powder coat finish. These brackets include precision fit laser cut 1/8" thick rubber gasket mounting pads as well as M8 × 1.25mm Stainless Steel mounting bolts. These brackets require you to tap (3) existing holes found in the OEM crash bar, as well as drill and tap (3) additional for a more stable connection.
