Yeah man I find myseld watching all the videos with him in it. His explanations are great.

Ah you Only watch car stuff. Thats only the car you own ?

Funny I watch for the same reason. He just speaks in truths, and automotive passion.

he must be fun guy to work with, i can't imagine him having a bad day at work

Do people make one for an r33 GTR? or is it the same as the 32's? also where do I buy one?

@@AjClarkPROJECTJDM Radium makes one for all of the GT-R's, the R32 was the last one to be made because it's different from the 33/34.

Got one for my a80 Supra to replace my external surge tank. If i surge its literally got nothing left in the tank and ive been well under E for a while

We got 65 whp with E85.

You can get that from a subaru with just premium pump fuel. Octane ratings are different here in the uk, but 91 equivalent to our 95. Which is bog standard fuel. Running 99 octane which would be just over 95 in the usa, gives around 30hp easily.

If ethanol destroys aluminum, then it destroys the aluminum cylinder heads and aluminum forged pistons?

@@sepg5084 it doesn’t sit on those components long enough to cause the adverse reaction that degrades aluminum. Raw aluminum fuel lines and none anodized parts will have issues. Even normal pump gas with 10% ethanol can damage aluminum part, if you have ever taken an aluminum carburetor apart from power equipment that sit for a long time between uses you’ll see lot of pitting from the ethanol eating away at the raw aluminum.

Technically true chemical alcoholate corrosion can occur with aluminum. However It is both temperature and water content dependent. As long as water content is above 0.5% the process fails to occur. Very good paper written by Jenny Linder "Alcoholate corrosion of aluminium in ethanol blends".

Ethanol does react with some plastics, but not all.

try Direct injection LPG on the GTR they love it will smoke a E85 fuel GTR with same specs and its 1/2 the price

Wow! A 2008 is like a unicorn in the states. We didn’t get them til 2009 here

Not to mention it doesn’t coat the rear of the car in the black sludge particles that are a pain in the neck to scrub off

It's not exactly corrosive, its dissolving the plastic parts.

It’s really more of a solvent action then corrosive action

I question this type of stuff because all modern gas has ethanol in it.

This one was totally melted and rubbery.

Me too, for both of mine.

Welcome aboard!

I don't think these are widely available. There are many other high capacity brushless pumps that are. This also has nothing to do with the context of this video.

@MotoIQ correct slightly off context of the video, apologies. Though think the idea of reducing failure points and current draw often valid points in any aspect of building a car. Yep many out there maybe a future comparison test would be interesting. Just an idea apologies if spoken out of turn

You could get the connector that matches the factory harness and only do the modifications after the factory harness. Simply remove the home made adapter to go back to the untouched stock harness.

A lot of it is due to the high resistance of the stock Subaru wiring. iWire makes a good pump wire kit. Our pump got a lot more quiet when we used this.

@@motoiq Yeah, it's a pretty slick piece. I love that it retains the 33/66/100 PWM pump speed of the factory fuel controller. Living in Florida I noticed a big drop in fuel temps on long drives now that the fuel isn't just constantly cycling through the rails at 100% pump speed. When I first started having the issue I hard wired the pump using the Radium harness and even installed thru-terminals into the factory sending unit with 10ga wire all the way to the pump but I was still burning them up. Eventually I started paying more attention to how sticky the plastic on the sending unit was getting and that was when I noticed the stuck check valve. Finally, I went full scorched earth with the Radium hanger, Radium fuel lines/filter, and iWire harness. I also integrated a fuel pressure sensor into the Cobb tune instead of just a gauge on the regulator so now I have a safeguard if it ever starts to lean out again. I have about 3k miles on it since all that in it's been rock solid ever since.

Same setup as us.

Glad to help!

Older EJ cars don't seem to have this problem, the newer FA powered cars have issues with the high pressure pump at more than 50% e85.

It is a good product but it wont fit in the hanger.

I have a feeling this may not be all R35's. I think some have different plastics

They didnt. Works fine.

It won't for long with E85. The dissolved plastic mess is very clear here and you cannot deny it.

@@motoiq Did you mean the Evo & STi stock hanger won't work for long or are you referring to the GTR?

@@DJ_Driven The GT-R, our STI and EVO have been on E85 for awhile with no issues yet.

Um how is the OEM parts melting having anything to do with a "non professional" installation? I guess the Nissan factory isnt professional?

It's made mostly from corn and other grain now.

I highly doubt it

Yes you are correct, at least for this reason.

Copied parts/kits and reverse engineered etc

As far as we know Radium does not copy other stuff and there stuff is pretty unique.

What's up Kevin!

Because chemistry!

@@motoiq Haha yeah :D Sucks that not all parts can take both right out of the box. The 5% mandatory ethanol in 98ron gasoline is useless anyway :)

Yes

It's Jeff's I sold all of my bikes.

Honestly ethanol hasn't been a real problem for decades now, but aftermarket brands have long capitalized on the worries people have about alternative fueling. Yes, you need larger fuel pumps. Yes, you need to flow more fluid and so it's easier to starve your pickup with high G's. The much cheaper answer is you just need to change your fuel filter and service your injectors more often. Super trick billet baskets don't really change this.

@@ngamber exactly, its the glue in the stock cellulose filter element that is being dissolved. The stock plastic surge tank can be soaked in e85 or e98 all day.

No it cannot, as you can see in the video, it starts to dissolve into goo.

@@motoiq please do your research properly, we reuse the bottom "plastic" part of the reservoir on 1800hp~ 2000hp r35s for many years already on e98 / e85 / meth.

@@yujyuj2957 yeah and it's super clear that it gets damaged by E85. If you chose to ignore this, then that's on you. By research, you are choosing to ignore the evidence we are showing you directly.

Probably less resistant plastic.

I’ve been running e85 in my boosted BRZ for two years over 15,000 miles no issue on stock fuel system

For an old car you need to replace all fuel line and plastic parts and components like fuel pumps and injectors need to be changed to ethanol compatible.

All cars I think. You need to make sure your plastics and rubbers are compatible with e85.

Our project STI does not seem to have this issue.

Plastic tanks on late model cars are made with some vapor impermeable plastic that is really resistant to ethanol. We were really surprised to see this happen on a newish GT-R though.

Good to hear. Thanks for the reply.

Im just guessing but I would assume that stock fuel tanks are still made of HDPE which isn't bothered at all by ethanol but fuel cells are safer in the event of a crash.

We were surprised because usually late model cars can take E85 better than old ones.

They sell them for many popular cars.
