Streetfighter Engine Oil Cooler Upgrade

[Streetfighter Mustang]

I hadn’t appreciated how much coolant piping was involved with the standard set up!

Yes , there is plenty to remove.
Our Streetfighter Oil Cooler Upgrade replacement deletes all the oil to water cooling and replaces its with a more efficient and robust oil to air cooling system.

No at all a stupid question. Possibly something that we have taken for granted.
Engine oil is filled and checked according to the dipstick level.
This will be the same , regardless of the extra 1l system capacity.

The only way someone would not fill with the correct amount is by filling to handbook specs without checking the dipstick.
The dipstick should always be referred to and engine filled to the marked full level.

David, Thanks for the information you have provided. I think that your kit has merit, and I am considering fitting one. I have a question in relation to your cooler layout and the oil sump volume being discussed above. Does the oil from your cooler drain back to the sump when the engine is shut down? If so, the oil level on the dipstick should be filled to above full if an extra litre is required by the system. If it does not drain back to the sump, each new oil change will be incorporating an extra litre of used oil (from the cooler).
Cheers, Bernie

As with most oil cooler components including factory , the oil stays within the cooler. This means that filling by correct dipstick level is required.
However the Streetfighter oil cooler sits above the oil filter. The Mustang factory oil cooler sits below the oil filter.

Streetfighter Engine Oil cooler
When replacing the engine oil, the majority is drained both from the sump as well as the oil filter removal. This is due to the oil filter being lower than the Streetfighter cooler.
This will allow most of used engine oil to be drained.

Factory Mustang oil cooler
When replacing the engine oil, the majority is drained from the sump only. Removal of the oil filter will not drain the factory Mustang cooler as it is mounted below the oil filter and seperate to the sump.The factory oil cooler retains most of the old oil within the cooler and the delivery passages..

Hi David,

Just wondering if you'd managed to get hold of a 2018 yet to test for oil pump pulsations?

Hi David,

Not as yet.
I suspect there is no difference as the 2018 has exactly the same oiling system as the 2015-2017.

I will keep you informed.

A special thanks to David and his staff for fitting the Streetfighter oil cooler to the two Victorian mustangs on Tuesday. Had a great time in S.A. and met up with a few of the local Mustang owners at the Prancing Pony Brewery.

Absolute pleasure to meet you all. It really seemed as you guys were having a great time. Great looking cars on our hoists.

We have seen several new aftermarket oil cooler designs that place there cooler significantly below the level of the engine sump and oil drain plug.
I would agree that the flaw with this style of oil cooler can retain up to 1 litre of old oil that cannot drain and would remain in the engine oil system.

Please do not confuse the Streetfighter cooler with this design as we have our cooler mounted much higher than the engine oil sump therefore ALL the oil is drained from the engine sump plug and cooler. ( as per picture in the previous post )
We have also incorporated a secondary oil sump plug at the base of the Streetfighter Oil cooler by pass manifold to absolutely ensure ALL old oil can be drained completely. This is critical for medium and long term engine protection.
No other kit on the market has these vital features.

I seen it thank you, keep me updated on the oil pressure switch

We now have a revised the oil pressure sensor that will more than cope with the Mustangs erratic engine oil pressures.
All available now and in stock to go.

 

[Streetfighter Mustang]

All Streetfighter Engine Oil coolers are now available with the optional of Oil pressure sensor kit. The oil pressure is displayed on an nGauge.
You can purchase the optional oil pressure monotiring kit with the nGauge include or alternitevely should you already have an nGauge you can purchase the oil pressure sensor kit on it own.

If your vehicle is supercharged we can also supply the boost pressure senor kit that will also read boost pressure on the nGauge

Have just come back from Targa High Country. Have been chatting with a number of different teams regarding oil systems in vehicles.

Not one engineer (Viper, Jag, Porsche, Corvette, Mustang) could agree that your concerns over the placement over the oil cooler in this manner was an issue so long as the entire solution was engineered correctly. One senior engineer in fact laughed off this as of no consequence and was suggested this was merely "salesman tactics" rather than a legitimate technical explanation.

Why do you place such high concerns over the positioning of the oil cooler in other vendors offerings when other vehicle chief engineers don't seemed to have highlighted any concerns?

We have been asked several times on how much oil remains in the oil cooler when engine servicing. The above explanation is a direct answer to the concerns of many. It makes perfect sense to drain as much old oil as possible from a system when carrying out an oil change. I trust any engineer would agree.

We have recently completed a full engine build on a Mustang utilisng our Streetfighter Oil cooler system. We have had to run the engine in with initial run in oil. It was critical to drain the engine oil completely after the initial run in period. The positioning of the oil cooler and components allowed for complete drainage of the oil system including oil cooler without the need for disassembly. This was especially helpful as we drained the total system 3 times within 600kms.
The car was run at the Adelaide Motoring Festival in the Spirit Series over 3 days.
The positioning of the oil cooler and air diverter plate allowed full ram air to both cool the engine oil and divert air unto the coolant radiator.
The Mustang ran 16psi boost at 950 HP all weekend with coolant temps at 90-95 deg an oil temps never above 105 deg .
We place high concerns that the oil cooler is positioned to receive cool air to do its job , it is a lesser concern and only becomes a matter of practically that it is also positioned to completely drain your engine oil system without the need to remove fittings etc to do so.
Engine oil coolers hold up to 1litre or more of oil. Our belief is to remove that used oil as easily as possible on every oil change.

Again we must clarify, that the Streetfighter system has the oil cooler thermostat situated in the delivery block, and the advantage of a a high mounted cooler receiving direct ram air and ability for 100% oil drainage on servicing.
