•••VERY IMPORTANT QUESTION•••
For the 335 intercooled kit on my 2013 Scion FRS, what kind of coolant do I use ? Does it mix with the radiator coolant? The OE suburu blue coolant ? Or is it something new? And how do I flush out and replace ?
*_Whoops! ...Now, I'm not sure if it was a slip of the tongue or just plain ignorance on the part of MRT Performace, but the 'Sprintex' blower (unless it has no longer uses Lysholm screw rotors) produces MAXIMUM boost at wide-open throttle from idle to maximum R.P.M. Period! ...If you run a boost-gauge you can see that simple fact for yourself... Another piece of misinformation from MRT Performace which I feel compelled to challenge is; never, and I mean NEVER EVER use a turbo (especially a small one) to boost the inlet of a Sprintex Supercharger... Why? ...Because that turbo will create a massive restriction to the airflow, and generate un-necessary heat_* 🔥 *_for the intercooler... Now, having said that, some daredevils at Bonneville Salt Flats have run large turbos after a Twin-Screw setup, but that can't be done with the setup shown in this video... Honestly, I wouldn't allow MRT Performace to change a sparkplug in my vehicle, let alone fit a supercharger system._* 👀
Hi how much gear oil it needs for the smaller charger in the video in terms of volume please ?
How will the 335 handle with the TRD version
Could you use the bigger blower with stock engine if your running e85? Or fit a oversize pulley to keep boost down. Just prefer to buy the bigger charger initially and have the option to up boost at later date if you get bored with power. Interesting at it doesn't really yield any bottom end, together with the scavenging effect does that mean bottom end would worse than stock? Thanks, good looking kit this one.
+Jeremy Schumacher problem is the bigger blower with an OEM engine needs such a HUGE pulley to drop the boost the pulley wont fit under the bonnet
:(
when i go to sprintex it says pwoer goes to 270whp which is roughly 220rwkw isnt it. but on ur vids u says the 210 is only about 160rwkw , which is correct
Hi, what constitutes 'Fully Built' I am considering this supercharger system as an upgrade. Can you please list out or provide me a link to the upgrades to the engine for the bigger supercharger to run smoothly. Thanks!!!

more on the blondie at the end!
sorry, she only makes minor appearances!

*_I find your experience of increased PSI with increasing engine speed confusing, that sounds more like the effect from centrifugal type blower, not a screw type, which is known for its ruler flat pressure response, regardless of engine RPM..._*
*_My own experience with an earlier Sprintex 102 model, was very different... At an engine, to blower ratio of 2 to 1 (engine 6k rpm, blower 12k rpm) we achieved 5.PSI psi... However, when we increased the speed of the blower to 18k, using a smaller blower pulley, we achieved our target of 10.PSI... My confusion is, when we mashed the peddle from idle, the PSI instantly shot to 10PSI and stayed there at 10.PSI all the way to maximum engine speed... So my question is... 'What caused your set up to have very little PSI at low engine speed, but increased as RPM went up?" ...Granted, running the blower at 18k we initially did have a heat problem, which we cured by cleverly encasing the blower case, in its own water jacket to control heat... We also ran an air to water intercooler at the intake manifold..._*
*_The engine was a modified 2.8L Volvo V6 with a high lift cam, 8-1 compression ratio running 10.PSI which idled at 950rpm and produced 230 KW, or 300 rear wheels HP..._*
we have fitted so many of these units we have lost count, all we can do is report on the outcome of the exact design on this engine, other applications will vary
How did you set up the water jacket
@@charleyssss *_The cooling water jacket for the blower was fabricated using a 2mm aluminium box which covered the top and 2 sides only... The water jacket gap was around 8-10mm, we also tacked fins to the inside of the box, and spaced them between the blower's casing fins, this created a labyrinth for the water flow which increased turbulence which helped with the cooling and the heat transfer... We first fabricated the template water-jacket out of cardboard, then gave it to an expert welder to duplicate it in 2mm aluminium... The outside edges of the box had a 12mm flat flange which matched the blower casing profile, sealed it to the blower case with a high-temperature silicone... We had a separate water circuit using a small 12v marine water pumps which circulated water through 2 tiny motorcycle radiators strapped flat against the underbody of the vehicle... With the intake manifold now ice-cold to the touch, we were then able to safely advance the spark quite a bit and gained considerably more power from the motor... Hope that helps._* 😎
@@phoenix11994466 Damn that's smart as hell. Thanks for answering my question.
8:50....On the top right, poster on the wall....someone wasn't happy with the track day?
naa it was an inside joke at MRT for a few months!
This video goes against everything I have ever heard. A centrifugal supercharger will build boost gradually and make all the power up top. A twin screw makes full boost instantly and holds it. Typically actually falls off some up top. Look at the torque curve. Every wonder why a sprintex car falls off after 6k rpm? Because the boost falls off.
Damnit I'm getting sick of converting from science to 'merica units
