Like what I'm hearing!

Phunk, will this eliminate the issue I had over the weekend where the top plate and the rods separated due to the weak structural linkage? Ie are you reinforcing or replacing that structure in this new product?

Also, would like to recommend that you start a new thread with a press release when you are ready so the conversation can stay focused on your product... will help when new people stumble across this issue down the road as well

Side note... NASA and some other sanctioning bodies assign "points" when you use a non-OEM fuel pump... will be well worth it to carry less fuel / weight, but just fyi

All of this sounds very interesting. Almost makes you want to buy even if you don't track hard core. I plan to track a handful of time next year with two this year. But it seems a must for anyone that might track. In for pricing.

Also big props to you for taking on this task and making sure it's going to be a great product.

I tend to believe that what happened to you over the weekend may be an isolated occurance. Our product is mounting on the opposite side of the fuel tank, and merely interfacing via plumbing with the OEM assembly that broke on you. It would not be too difficult for us to contruct some structural reinforcement for the OEM fuel pump assembly if there is a problem with its integrity. It would be entirely independant of our starvation resolution product.

I will definitely start a new thread for the finished product. We want to market it with a little motivation, I think it will be a popular product.

It is strange that they assign points based on a fuel pump upgrade alone, as a fuel pump doesnt increase horsepower or anything. But it is for certain to enhance track times if you dont have to drive around a problem or deal with momentary power loss.

my bad... here's the nasa rule, there seems to be some flexibilty... was going off memory... but it looks like if you have a different pump and ecu tune you take points for both (+2 on this rule, and +x for ECU rule)

6) Non-OEM or modified carburetor, fuel rail, fuel injectors, fuel pump(s), and/or fuel pressure regulator +2 (no points for fuel pump alone if using OEM fuel and timing maps, sensor inputs and ignition timing)

in any event, this is just a nit... great to hear about your progress!

This here is a sneak peek of the CJM solution to fuel starvation in the twisties. This is all I can show for now. It is what you would call a fuel surge tank, but we have expanded on the theories behind them and added some extra functions. It will be marketed as the CJM Serge Tank, pronounced "sarge" as-in "sergeant". Because its the boss like that.

It is of course shown here in pre-production status... so it is in raw machined and fabricated finish.

travisjb 09-09-2011 01:50 PM

Looks great

2cents re name... how about:

"Fuel Sarge"
or
"Slosh Tank"
or more to the point...
"CJM Anti-Fuel Starvation Tank"

Serge Tank sounds like a nickname for Sergio

... consider selling this to Nissan Motorsports and maybe Nissan OEM can license the design from you?... hopefully you've filed for the IP

When you're ready, might also want to post this on the forums with NASA, SCCA etc... those are going to be the guys most familiar with the problem

BTW, looks heavy... how much does it weigh?

phunk 09-09-2011 02:15 PM

complete weight with fuel pump and everything is 3.5 pounds. supplemental installation plumbing etc will probably weight about 1 to 1.5 lb

travisjb 09-09-2011 02:50 PM

not too bad

SPOHN 09-09-2011 06:48 PM

Fancy

ChrisSlicks 09-09-2011 07:50 PM

5 pounds sounds good to me, that's less than the weight of 1 gallon of fuel. You could call it "Big Sarge", or "Sarging". You'll have to google that last one :)

Mike 09-09-2011 10:45 PM

I just want to call it mine!

MightyBobo 09-10-2011 08:27 AM

[RICER]I will only buy it if it has a burnt titanium finish.[/RICER]

phunk 09-10-2011 08:31 AM

i cant wait to show you how cool it is inside! outside is sort of boring.

spearfish25 09-10-2011 02:03 PM

I'll definitely be checking this out in person.

Elysium 09-10-2011 04:02 PM

I'm first in line! lol
