CJM Fuel Starvation Control Product, Round 2
 

It's time again to start on a second batch. The last few weeks I have had increased interest in the product, and I feel I should get a start on the next batch.

Here is how I would *prefer* to do this (also open to suggestions): $150 deposit to lock in. $1000 due at shipping (free shipping in the 48 states). I will hold reserved units up to one year for any buyers who may need to wait to make the full purchase but want to lock in a unit for their next race season. This pricing is for 255lph output. For boosted applications that exceed this in fuel requirements, there are additional upgrades needed and a custom order has to be configured.

There is room for a group discount if the quantity exceeds my expectations. That will be an open and transparent discussion if we end up with more people than expected signing up. I am expecting 5-12. Past that I might be able to twist some arms.. But please understand that quantities under 50 generally make a machine shop cringe or turn a customer away... So any discounts will come directly out of CJM's margin.

I would like to do a sign-up list for the rest of August while I prepare. It will take me some time to reestablish contact with people who asked me to notify them of the next run via email and find out if they are still in the market.

September 1st-6th I would like to accept deposits, and set the production number. I will make a small handful of extra units for late sign-ups. Say 10 people deposit, I will probably make 15. So, there is definitely benefit to signing up before the deadline. If I know how things work in this industry, whatever extra units will sit and sit and then once people realize they are the last available ones in existence they will go *poof*.

Here is the part you guys won't like. I am requesting 12 weeks to complete production. This means pushing into December. I hope to beat that by 50%... But with all the changes around here lately I hate to try and make premature predictions. The larger the batch, the easier it will be to push it through quickly. Regardless, I will keep everyone updated with photos every step of the way.

For any of you who have enjoyed this product from the last batch, I would appreciate a sentence or two of your experience with the transaction and/or product. If not, I will go into the old thread and copy/paste your old posts :)

Tomorrow I will try and get some product details in this post for those unfamiliar with the last batch.

Thanks!

Last note: if I am unable to get 6 sign-ups, deposits will be refunded.

In for sure. Wish you did a deposit last time, good idea.

I've got nothing but good things to say about the kit and phunk. The kit works. I've run my tank down to one light on the fuel gauge twice now during trackdays with no problems. And for phunk. He's one of those rare people you meet every now and then. Eleven o'clock at night. He's answering my text. Can't beat that. Sounds like I'm a fanboy. You're right. I am. :tup:

im in and dont mind waiting, gives time to save up

I really liked mine from the first batch, too. Top-notch seller/shop, good support, works as advertised!

I was at a point where I could starve the car on my favorite track with just 3 dots blacked out at the top of the gauge. So I'd usually fill up after every session, maybe sometimes I'd get risky and fill up every other session if the track/direction didn't involve a long right-hand sweeper. Now I just fill the car in the morning and run all day. I've finished up my final sessions south of the 1/4 tank mark multiple times now and never had an issue.

Saves time not re-fueling between sessions/classes, saves worrying about the starvation on-track if you didn't have time to top up after a session, etc.

Also, a gallon of gas weighs about 6 lbs. Our tank holds about 19 gallons, so full fuel load is 114 lbs. So that's 57 lbs gone from the car if you start your runs at 1/2 tank instead of full, or 86 lbs gone from the car if you start at 1/4 (which is doable for a 20-minute HPDE session, but any longer and you might actually run out of fuel).

I'm in but unlike Clint hate waiting lol

It would be so interesting to have a flow sensor on the line between the OEM fuel pump and the surge canister. We know how frequently it was starving in the stock configuration.. but we have no real data as to how well our product's secondary function (of supplying extra fuel back to the stock pump) is working. The goal of that secondary function being; to help aid the stock pump from running dry and self destructing. Of course, the OEM pump will starve more as the tank level is lower. That window should be reduced by the secondary function.. but how much?

It appears we have made it through this season. But I am very curious how long you guys will be able to go before the OEM fuel pump needs replacing.

Feel free to add a flow sensor to mine to test!

So sad.. I am so broke..

Most important thing here is Phunk him self. Great guy. Always giving time to answer my questions. This product works flawless for myself at the track and soon (hopefully :eek:) on my TT kit.

anyone who purchases this will not regret it. It is the BEST mod on my car. Its so nice not to worry about fuel starve anymore. The stock fuel pump setup is a fundamental flaw in this car, and this is the only solidly engineered solution.

In for sure.

Count me in.

I'll get back to you on this one... I want in, but I need to talk to the Wife on it lol.

Not bad for limited exposure and 4 days. I am going to dig up some saved emails from people who wanted to get one of these.

Lets do a group buy on Shamu's 100 gal. tank with enough fuel pumps to run a aircraft carrier. Bwahahahh.

Shamu if your reading this just kidding. Maybe. ;)

I'm definitely in,

I'd like to get in depending on the pricing of the FI application. I have an upgraded 340lph pump now so I don't want to demote this pump to just feeding the new pump in the kit. I wish I could re-use my old stock pump to feed the upgraded pump.

so after everything.. this unit is $1,150.00 shipped?

We will have to have a little phone conversation to go over the various ways we could set it up for you.

correct!

Count me in as well.

So if I understand correctly, $150 deposit in early Sep. Balance ($1000) due later when product is ready to ship, (approx. December), free shipping and if $$ is an issue, you will hold one on the shelf for up to one year for customer who put down the $150?

follow up ? in the other thread, Phunk, you mentioned that the line in the tank isn't in tank rated but you've found/sourced a line that is now? What will be included with this batch?

The lowdown on the lines is here: http://www.the370z.com/track-autocro...ml#post2446368 . The bottom line is that the alternate line would be a significant cost increase in the kit, and the lines in the kit are a reasonable choice in terms of cost and durability.

I'd pay the extra $200 or whatever it is in that range to get an in tank rated line honestly.

This is all correct!

I am going to determine that later. For now, I would assume it will use the AQP hose previously supplied. Once I know how many units to make, I will know how many feet of hose I need. With that number, I can get a quote and find out exactly what it will cost for the SAE rated hose, and see if I can sub it out to that. If I cannot get it for a reasonable cost on it, then I will have to leave it as optional.

ok, sounds good, obviously the original hose seems to be just fine but if it's an option in the $$$ range I listed give or take, I'd def be interesting in "upgrading".

I agree... if it was dollar for dollar the same, then there would be no excuse ever not to use it. I hope that I can get it low enough in volume. Ideally, low enough that I can even keep it on hand just in-case by some chance someone did experience an issue with the AQP in the last batch. Maybe I will nag Mike or Spohn to open up their tanks and have a look-see at their hoses... they are the first installed users. If there is going to be any issues, they would be the first to know.

Funny you say. I was just in it a month ago. Looks flawless as day one. Can't remember when I installed your kit though.:icon17:

We are at a production worthy number now. Probably pick up a few more yet!

I am interested... but I am boosted(single T) and need more info.

Boosted guys: Our road race fuel pump kit uses a Walbro 255 to feed the engine. This pump cannot be upgraded or replaced (except with the identical model). If you want to run it how it was designed and tested, this pump *must* remain the primary pump in the system (see final note below). It is not a normal 255, it is a special model and has features we do not want to lose. However, there is an additional pump holder that can hold another 255, 300, 340, or 400lph pump. Anything with the typical Walbro diameter.

Costs to add a secondary pump:

1: cost of pump itself ($80-250)
2: cost of hoses/fittings to integrate it ($30-50 minimum)
3: cost of an activation system for the secondary pump, such as a hobbs pressure switch
4: optional; cost of upgrading OEM sending unit pump, to make sure the road race pump gets enough fuel (will be needed for larger output setups, or when running a secondary pump full time)

Example 1: If your HP were just BARELY beyond the single 255s reach, we would just add another 255 and splice into the line to the fuel filter, and you would be set. Thats like $125-150 plus a hobbs switch. You might not need a hobbs switch if you already have a 255 in your OEM sending unit... but I really must say that it is better if the secondary pump is not full time running. The stock regulator will not be able to handle that type of fuel volume, and you would need to add one of our return systems with external regulator. Even then it sounds troublesome.

Example 2: Moving to the other extreme, you wanted to make 1200HP... then we would run a 255/485 combo in the road race pump. You would run probably a 340 in the OEM sending unit. We would complete bypass the OEM filter and regulator setup, integrate a full return solution and billet external filter.

So this can swing around all over the place. It really just depends on the power of the car. If the HP is within the realm of flowing through the stock filter and fuel lines, then we are talking about the first example.

I know this is frustrating to try and figure out... but there are probably 100 different combinations we can go on a fuel system in these cars... and I cant possibly test all of them to make nothing but guarentees on all of them... I can only tell you what has been done/tested already, what I think would work, and what I think isnt the best idea. Due to this, a private phone conversation is probably in order for anyone exceeding 500rwhp or using E85 with boost at any HP. Built engine HP numbers will need like an entire consultation LOL... basically the higher the power you are running, the better I will want to make sure you understand how the system is working so that you can make educated decisions on what you want to do.

note: testing of the unit with an Aeromotive 340lph as the primary pump instead of the designed-in 255 would be OK, but I cannot guarantee 100% flawless function of the unit configured that way. If it did work flawlessly, than it would only mean I over-killed the initial design of the product. I am skeptical of it working out alright.

if you need a boosted Z to work on, let me know, my car just sits while I am gone, and during winter

I'm in

Sign me up, just for the peice of mind I can drive under a quater tank safely.

Best of all it looks like a professional product with exceptional support.

:happydance:

Quarter tank? You are lucky, I can't get to even 1/2 a tank before I start having issues now. :(
