Fuel Starvation Control Product

Shamu

I'd expect someone marketing fuel starve product to have this take. Don't blame you at all. Just think my solution has more value than you think. ...and you can't beat the price! What is someone into with your solution once they pay for labor and all parts? $1500? I have $1200 to spend on other stuff I need like a diff cooler and few other track focused items.

I think it's a great solution for people who want to keep car very stock and not really molest the car though! Awesome work! Curious does it add much weight? My car lost over 15 lbs.

Sorry not trying to thread jack, but I had a little issue and figured you guys could help.

Question is about fuel starvation. What is the consequence (or car behavior) from the fuel starve? I will give some detail on what I experienced a few days ago.

I was accelerating up an on ramp to the interstate, was in 4th gear rolling onto the throttle and coming out of it planted. About 50 feet into the straight at 5k rpms it reacted like I hit rev limiter. Vitals looked great so after a mile or so I done a WOT in 4th again and it did not happen.

Later I took another right turn but much shorter maybe a 80 degree 100-125 FT turn. Same thing as I came into the straight around 5k rpms it acted like I hit the rev limiter. I played around all the way home and it did not do it again. Only after these right turns.

That said, I know a long sweeping right turn causes issues. What are the issues exactly (fuel cut car reaction)? Does it hit you while in the corner? Or in my instance's I was in and out of the corner quickly so the lag hit me as I was coming into the straight?

I had a couple dots over a quarter of a tank of fuel remaining, also the car is TT.
Thanks for any input I will rep when it recharges I ran out for the day!

If it was marketing I was worried about, I would have had your several posts in my paid sponsored thread removed. I believe everyone should be exposed to all their options. My product turned out to be more expensive than I was hoping, and I have no problem with anyone seeking alternate options.

The thing is, it is my thread, and I am entitled to criticize things posted here that I don't entirely endorse. I will not deny that what you have done is functional... But while you point out the many benefits to what you have done, I simply point out what shortcomings I see.

My product so far has only been installed by the customer, so their final price is the same as the retail price. I am skeptical that anyone is going to do what you have done for $350... Most shops are going to charge at least that just to remove and reinstall the tank, and fab work on top of that.

Aside from that... If anyone removed their tank and sent it to me, I would gladly replicate what you have done.

What is going to be your solution for the fuel level circuit having the missing sensor?

This is fuel starvation all the way. Tomorrow I will right a detailed response... This is difficult to do from my iPhone!

Shamu forgot to mention, my product should add in the area of 5#. Ill give you exact weight tomorrow. It's minimal and of course is extremely countered by the weight savings in fuel quantity

Thanks so much! That keeps me at ease at least. I may purchase this in the future because I may track this car one day.

Question for those of you that have made this modification (Spohn, Mike, et al) what are your lap times before/after the fix?

Mike

no different, just get to do a lot more laps per fillup.

So you haven't gone around with <1 gallon to see how much time you'd save?

Shamu

It will be cool once this solution has been thoroughly tested by track drivers who have had fuel starve issues and to see how low people can go without an issue.

Does this product carry a warranty? And curious if you install this will it void manufactures warranty if it were to impact fuel air ratio and cause engine failure? That's probably important for people with cars still under warranty to know.

Shamu,
I have gone down to bone dry with no issues. I don't see how it can affect fuel air ratio, its just another pump on the other side of the tank. The fuel pump doesn't meter fuel to the engine.

threeseventy, I haven't checked times for that. All of my times are pretty consistent with full or empty tank though.

I could have really used it this weekend at CoTA. I began fuel starving 12 minutes into a 25 minute session. What is worse is that I was starving at three different corners by the end of the session. This will be my next modification!!

O&G

how does a surge tank / extra pump affect A/F ratio?

Keeps it from going to infinity unintentionally.

Rusty

In simple terms. Without it. Fuel moves away from the pump. Pump starts to suck air. A/F goes lean. Motor shuts down.
