Alk injection and abraidable SC Blades

[NoRemorse]

As I am reading more and more, a lot of people reccomend NOT injectoing PRE blower on all eaton gen 5 blowers. The blades have an abreadable cotaing on them meant to wear down so that all the parts tolerances are EXTREMLY tight. It has been noted that injecting preblower will wear this surface down, (because that is what the surface is designed to do) possible loosening all the internal tolerances with the SC blades.

It has been noted that spraying POST blower has it's fair shore of issues. Such as atomization time, not cooling the blower, and spray pattuern not being equal between cyelnders. I just thought I would bring some of my thoughts to light and see what everyone esle thinks.

It in all honesty, doesn't seem like this is a very safe way to go in the long run. Pre-blower it is effective performance wise but vs the cost of rebuilding the supercharger...not worth it. Just think...the cost of 4 of those meth kits is almost the cost of those supercharger you found. Get what I'm saying? Then you could sell your M62 for about $400 also so that puts it even closer to the cost of those superchargers.

Then like you said, post-blower hasn't shown well of dropping IAT2s and not be spread evenly between the cylinders.

Could it be possible to spray a smaller amount post blower? Could that help at all? Instead of having a good 120ish octane mix, we could definately live with a 100 octane mix. I think 100% meth should evap quicker that 70% meth 30% water right?

About the blades, they definately are delicate. But its expected. People have been spraying pre eaton for ever and a 1/2, and yet, the debate still continues.

The abradable coating is new in the GEN V blowers, so only the past few years has this been an issue really. If they were not coated like this, I would say screw it, it'll be fine, but that's not the case.

If you do that then why spend that much at all and just buy some 110 octane at the track and switch your tune before you go race? Cost of 110 octane here <$7/gallon. Only need about two gallons in your tank when at the track which will mean less weight. Put that against the cost of a meth kit plus the cost of getting it refilled...

you guys need to inject smaller droplet size, aquamist makes jets able to do this, hell they even make jets able to inject preturbo.

damn, that's something to look into then! thanks

Well if we buy those, does it still make it a sufficient enough amount to see lots of gains? Keep in mind that we're used to spending little and seeing good gains. I'm not about to spend several hundred for maybe 10whp, if that because it needs to be proven. We spend $800 and we can get 60 or 70 more than stock.

The electronics you need to properly setup a "wet" shot have never been very cost effective on FI cars. I agree with above, there are better ways to improve efficiency of the engine (higher compression is one). The high-silicon content pistons have never been recommended for N2O do to resonance issues (they CAN shatter).

I say F it. Now that I have 2 superchargers, If I screw one up I have another to fall back on. I've had this kit for over a year and dam it I'm gonna use it.
