Just wondering if there's a ceiling to the amount of fuel the fuel filter will let through and if at some point this will restrict the hp level. This is on a 94 CX. Are some of you using an aftermarket filter? Just trying to get all the questions answered before the project hits the garage. Thanks.

I am interested in this as well but for a different reason. I'm getting plenty of fuel but have been considering upgrading to an aftermarket fuel filter purely for appearance reasons... anyone using an aftermarket filter?

Also does anyone run fuel coolers?

I dont runa fuel coler, but I do run an aftermarket filter.. I think you'll find changing even to a new filter will help out..
If you ever put in a custom tank you'll need to change the filter after a day or so, since most tanks have a bit of crap in the bottom of them..

I have often questioned the use of fuel coolers. It seems it can be argued both ways on whether they are effective or not. On one hand, fuel atomizes when heated, so pulling heat from the fuel could hamper atomization and have a negative effect on flame propagation and mixture hemogeny. At the same time, cooling the fuel would increase its density meaning more BTU's in the cylinder.

It seems that a setup with fairly high intake air temps would probably benefit from cooled fuel because the fuel would vaporize and absorb the heat, as well as create some additional detonation resistance. I would think that forced induction cars would benefit from this more than NA cars for sure.

i saw a turbocharged V8 make a extra 18 hp and 8 or 9 ft/lbs off of a homemade fuel cooler once, was kind of interesting but on a honda motor i dont know if it will make much of a difference and i agree that if it does it would be on a motor with hotter intake air temps.

Just in thinking of this further, it seems that this would be a viable solution to fight detonation in a setup that is pushing the limits of the fuel it uses. Thats just the thing though, this is more of an anti detonation application than it is an increase in horsepower application.

I think if the engine in question is creating enough heat by way of either plain combustion or high intake temps then vaporizing the fuel upon entry to the chamber shouldn't be an issue. If your depending on cylinder temps to do the work though, then intake port texture and design should play a role in increasing atomization to reduce port wall "wetting" in whatever way possible.

I'm personally running an Earl's fuel filter with my EG/K20 setup. Seems to be holding and running just fine, but I don't know if the stock EG fuel filter hampers performance or not, i'm sure it doesn't though. I ran the Earl's filter for vanity reasons...

Pics of the Earl's? How much did it set you back?
