check this out, i've heard of them recently, but have never seen one or really know anything about them. racepumps.com (http://www.racepumps.com/index.html)
i really like the simplicity of them, and never have been a huge fan of electric pumps. very versitile and adjustable, and a super clean install, too good to be true? seems like a nice candidate for my possible next project.
any thoughts or comments?

Sean,
I think Jody or someone posted about this pump not long ago. If it works as advertised it looks like a slick set-up and should be clean. I am always a little leary of new stuff like that until I know someone that has tried them. Sometime I will be the test rat but not for $300. I say you buy it and let us all know how well it works, LOL.

hmm, designated guinea pig.... ;)
actually, if i ever run into fuel delivery issues with this motor, i might just be willing to. i'd rather try one of them than mess with an electric set up. i'm running a superspeedway BG mech. pump right now, so untill i add boost or nitrous to the mix, i probably will be good for now.
it would be nice to hear more info on them, but i could see one in my future, even if i have to be the TC guinea pig for them. if it ever happened, of course i'd give full details, as always :thumbsup:

I've got one. My Camaro is mainly a street car, but I lost the fuel pump lobe on my last Comp Cams hydraulic roller to a Carter high flow pump. I called Comp Cams and they reported that high flow mechanical pumps can wear the lobes. The race pump seemed like a good solution.

I've had it for about a month now and unfortunately I can't give it an unqualified thumbs up as yet. My problem has been vapor lock. Never experienced it in this car ever in 20 years, but first hot day here in Seattle the engine died at an engine temp of 210 degrees. I knew it was the pump as the fuel pressure guage after the regulator read zero as I tried vainly to crank the engine. The next day, also a reasonably hot day, I couldn't make a full pass at the track. Not 100% sure it's fuel related, but it would appear that way.

So now I've insulated the 3/8" line in the engine compartment, but haven't had another hot day here to test the vapor lock problem. It works fine under a less stressful 20 mile drive back and forth to work. I'll try and overheat it again tomorrow.

It's a beautiful piece, but one other question I have is in regards to the built in rubber gasket. It resembles the o-ring material I have as a gasket for the thermostat. That gasket is not reusable. I don't know if the racepump gasket is reusable, but if it isn't, the only place you're going to find a new one like it is from the manufacturer.

A follow up on my reply - I just stress tested the race pump after insulating the fuel line inside the engine compartment. The pump worked fine through an engine temperature of 230 degrees with no sign of vapor lock. Of course, then the engine was pinging like mad while driving until it cooled own.

So the race pump gets an unqualified thumbs up from me. 10.3 static compression ratio doesn't, but it's always something.

hey, thanks for the report/update :thumbsup: .
so so far it sounds pretty good, maybe just a bit sensitive to heat. right now my B/G fuel pump is working fine, but i was looking into options should i need an upgrade, and the race pump seemed like a better way to go than electric. sounds good so far.
so grijo, ever make it up to pacific raceways with your car?

Yes, I get to Pacific Raceways from time to time. Now that I think I've got the fuel pump problem figured out, I'll surely get back soon. But I gotta tell you, it's been a rough couple of seasons mechanically. I now have a little voice whispering inside my head, "If you race it, it will break". I've blown my budget for this year on new parts to fix last year's failures and kinda want to keep it together while the weather is good.

cool. i have not had my car out there yet this year either, in the process of buying a new house, so i've been avoiding any spending untill its all done. i do however wrench on my buddys pro street car, and we've raced there a few times this year.
i know what you mean about the "breakage" issues, mines been very reliable, going on four years now, but i've been around drag racing long enough to know how quickly that can change. so i've been enjoying cruising mine a bunch, and racing with my buddy (which also keeps me from going overboard on mine), so untill the house closes, it will probably stay that way.
oh well, i still get to take it out :thumbsup:

I'm just returning from the track, and after one non-pass down the strip, I am taking back my endorsement of the Race Pump. I have suffered several vapor locks in the few months that I've had it, but the most recent two have put me over the edge. I thought I'd stress tested the pump sufficiently to an engine temperature of 210 degrees and have installed both heat shielding to the fuel line and the recently supplied pump gasket sent by Race Pumps specifically to inhibit heat soak. Twice this week the pump has failed anyway - once in bumper to bumper traffic on the freeway, behind an accident, and second today, ironically in the slow moving line to get in to Pacific Raceways, with maximum engine temperature of 195. I sat for an hour before entering then waited another hour before my first non-pass. Fuel starvation was apparent almost immediately. While waiting the first hour I noticed in particular that the Race Pump was hotter and remained hotter than even the headers. I'm sure the Race Pump is a great circle track high volume pump, but it is susceptible to heat soak and, in my opinion, not a viable street/strip pump. The Carter mechanical goes back on tomorrow.

Rodger from C&S Specialties in St. Charles MO told me not to use one. The reason inconsistent fuel delivery and pressure, the two things you want in a good fuel system.
