composite fuel rail

[banishedmunk]

I have been looking alot into fuel cooling and keeping fuel temps down. Skunk2 makes a composite fuel rail for the 4g63. How do you think it would work compared to the billet rails when it comes to heat soak and fuel temps.

Fuel spends .005 seconds in there before being thrown into the motor. It does not stay in there long enough, not to mention gas in your tank is always 30+ degrees cooler than what it is outside.

If you gonna ponder money on this, upgrade the whole fuel system and lines to -6/-8/-10 an fittings and lines.

It still sits in the same place as the stock rail. The entire thing will end up at the same temp as any rail.

But there are still benefits to fuel cooling, so I wouldn't disregard the idea. Many race cars run some form of fuel cooler. On the street you probably won't see a difference.

No one claimed otherwise. He just said for the amount of time the fuel spends in the rail, it isnt worth the effort.

It probably won't make any difference at all. Our fuel rails are spaced from the head using those little black plastic spacers, and those are going to provide somewhat of a thermal barrier.

I wasn't trying to make it a big deal. I just tried to say there are benefits as well. But since you bring it up, I do take it that by claiming that fuel spends .005 seconds in the fuel rail and that it is 30* degrees cooler as trying to extinguish all other possibilities for benefits.
If you examine costs vs. benefits, then it won't be worth an effort (that I agree), but it may be worth something to someone. Cool?

BTW, I think the intention for the composition fuel rail was to be able to work with meth.
