1.5T PRL Motorsports Civic X 1.5T Product Development

Impressive CVT cooler there!!

 

whats that piece on the right? is that it the OEM CVT warmer?

 

That wouldn't be a bad idea, but it shouldn't be necessary unless the maintenance is due. We are expecting some fluid that will need to be added to accommodate for the added line and cooler, but we will addresss this when we get there.

We wish we could've had this available for you then as well!

Pricing will be published in the next week or two once everything is finalized.

Thank you, SiR!

Correct, these cars come from the factory with a CVT warmer, whereas we are replacing it with a CVT cooler. During initial testing, Hondata noticed that CVT trans temps were through the roof, so they briefly experimented with a similar cooler setup with success on their endurance car. Honda gave these cars a warmer for a reason, so we would like to collect data and see if the warmer's pros outweight its cons before making a cooling system without a warmer available to the public for street/daily driving. We have reason to believe that we will be fine!

 

Can you retain the warmer somehow? I live in a place that gets cold in the winter...must be there for a reason..

 

Ahh stock "warmer" my bad, very interesting... we should see a great improvement then!

 

With this design we will not be retaining the warmer. As stated earlier, we will be testing to see how essential this warmer really is and outweighing the pros and the cons of the warmer and cooler. If we come across an issue or need, back to the drawing boards we go. Until then...

We got around to dynoing our Project Snow White Si earlier today. While we were at it we decided to do some before/after runs testing our Stage 1 intake system. We never really anticipated this kit to be a big power maker, more or less a simple bolt-on mod for customers looking to improve aesthics and air flow. With that being said, we were rather impressed with what we came to find during testing.



We recorded four dyno pulls with the Stage 1 Intake system. During the four 3rd gear pulls we noticed that the knock control value continued to drop, which shows an increase in efficiency, whereas the knock control value with the factory intake system is rather sporatic. As this knock control value decreases the ECU continues to add timing and allow the car to make more power. We began testing this morning with the stock intake when the temperature was in the upper 60's. These numbers and gains held consistent into the late morning when temperatures rose about 7 degrees Fahrenheit into the mid 70's. Our stock 10th Gen Civic Si made a best of 200 whp and 210 ft/lbs tq on our DynoJet.


Here is a 3rd gear comparison of the stock intake system and our Stage 1 intake system. We chose to compare these runs because of how identical knock control values, coolant temps and air temps were (within +/-1%).


Here is a 4th gear comparison of the stock intake system and our Stage 1 intake system. Again, these two graphs show identical parameters.

With that being said, we managed to see mesaurable gains with our Stage 1 intake system in comparison to stock. Customers can expect a 4-9 whp gain without a tune by simply bolting in our high flow drop-in filter and silicone intake hose. We expect to see MUCH larger gains with our cold air intake system.

 

An inline thermostat may help it warm up faster during winter. Derale and Earl's makes them.

That's awesome to hear as I got the hose on with my AFE dry flow and felt and heard a difference and thought placebo but I guess not!!!!!

 

Love it so far

 

We expected a somewhat audible difference in sound difference and small smaller performance gains (3 - 5 whp); This system was mainly intended to be more of a maintenance upgrade and cosmetic mod that gives minor gains at the same time. We couldn't be any happier with the results!

Glad to hear it!

 

I still haven't gotten mine yet!

 

More updates! Our prototype is complete! We will be testing next week! All piping will come standard powdercoated textured black.

 

Can't wait to see how it performs an absolute work or art!!... also waiting to hear more about the Cobra Race CAI as well

 

Will you guys be making a Short Ram Version for the SI

since im in Canada..Cold air wont fit

 

I believe that @VitViper had tested the PRL Downpipe with the regular 1.5T EX-T, and determined that the gains would be very impressive, but that he was limited at the time by the electronic waste gate. Since he has since indicated that the new 2017 SI does not employ this boost target dampening below a certain speed (40 mph?), I was wondering how strong the effect on a 2017 SI would be?
