Rookies Throw This Out! Fuel Damper 101 [TECH TALK] 

I just ordered a radium fuel pulse damper for my 1j as well lol. I got rid of all the dumb stuff under the intake manifold, I figured the oem damper was there for a reason so I got this. Did you get the extended range version?

@@stellaroid, if you mean the XR variant, I did not. when I spoke with Radium they explained that was for higher fuel pressures than what I'm running, so I opted for the more compact R version. (not that there is a detriment to using the bigger one, but I wanted more space) R = 40-70psi base static fuel pressure XR = 40-120psi base static fuel pressure

@@DylanTK where did you mount yours? I'm going to mount it on the fuel rail where the oem fpr was.

​@@stellaroid, I drilled out the center port on my HKS rail and threaded it for 3/8npt. If I could redo it I'd get a bung welded on and use the o-ring version, but you cant win em all lol.

@@DylanTK I can't find a 3/8npt female to m12x1.25 male adapter so I'm gonna weld my own adapter together. I'll just use a crush ring/washer to seal it to the rail. I think it'll work out pretty good. My fpd should be coming in today, I can't wait.

Is he still tuning cars?

Which one did you use?

@@jeff666p the radium rising rate ones which inserted onto the radium rails I had used on an EJ20

It can certainly be a bit of a tail chaser! - Taz.

It took us and some seasoned pro's more time to figure out than we'll ever admit lol.I dont race and tune as much these days as I used too since I joined a APBA race boat. But still I'm amazed at the information you guys are putting out there. If I had access to your videos and classes when i got started I could be retired a rich man just on my savings from not blowing stuff up ;-) Please keep it up and hopefully you guys will get the recognition you all deserve.

4 years late, but yes. My oem Toyota rail uses one and most newer cars do as well with their return less setups.

Well good news for you Radium offers a fuel press reg and damper built in.

Thanks for sharing that Matt! - Taz.

Syvecs:)👍👌

oem one sucked, but the radium one doesn't

Yes, units like this are a good replacement in the case of faulty OEM ones =) - Taz.

Not where we're from sorry Jim 🤓 - Taz. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-pGZz71V07t8.html

Engineers say damp-er ...... damper.

Guy's a Kiwi. Enough said!

Read this :) grammarist.com/usage/dampen-damper-dampener/

They seem to be synonymous from the various grammar guides and I use and have read both versions. Seems to be an American/English english thing ;-) As for the need, or effectiveness, of devices to moderate line pressure, some argue that they are not needed but I figure that any pump is going to introduce pressure fluctuations - and, remember, there will also be fluctuations from sudden variations in the fuelling demands of the engine due to the inertia of the fuel in the return line*. Someone suggested a pressure regulator would remove the need for a damp(en)er but i would remind him/her that there is a pressure gradient across the opening range - eg. while it may just start to open at 3 bar the maximum opening of it's valve may be at 3.1bar (could be lower, could be much higher for poor quality - cheap/counterfeit - items) and any internal friction, etc, will cause some sticking that could further introduce fluctuations so, depending on the characteristics of that particular installation and the components used, you could be asking for an engine failure. *Look Velocity Head in fluids :-)

High Performance Academy Nice, looks like we were both right?? I should just stick to engineering instead of grammar.

Yes, unlike America we use English English, not some other English, which isn't really English at all now is it ?
