The fuel cooler just to the right of the Y pipe will drop fuel pressure at the rails... it did on mine... so we by pass it.

Very good and informative post. I got a good out of the "CREATURE". A close up of that thing in dim lighting would make for a good movie monster.

 

Martin, Thanks for taking the time to actually SHOW where the restrictions are and what you see from the mock test. Sure we "knew" this a while ago, but I have yet to see anyone else "SHOW" me "what" was happening, with measured and accurate data.

Bravo!!! BRAVO!!!!

I talked to Todd about this and he did not advise by passing it. He said the tank would overheat. Much hotter in Ca and Az then Chicago. oh Marek thanks for all the tech support, the car is running great. Your intercoolers worked out awesome. thanks Greg

 

Outside temp isn't the issue with fuel tank heating - circulating the fuel round and round through a high pressure pump is where the heat comes from. I've not seen this fuel cooler so I'm not familiar with it - how exactly does it work?

 

The fuel cooler is mounted on the suction line of the a/c unit. It must have a sensor that turns on the a/c compressor as needed, then it must turn on the heat to compensate for the unwanted cooling inside. german engineeering.

 

That's what I call R&D...Great job.

 

Looks like Todd took care of you...
thanks for the kind words.

Keep in mind that the jet system has certain requirements to be able to siphon the legs of the tank to the built in sump. It cannot be bypassed or you will only be able to use 1/2 of your fuel tank The top half

Has anybody tried running a seperate smaller pump to take care of the in tank spray duties?

 

I respectfully disagree that running a second fuel pump the way we do on stock pressure can be devastating. Protomotive has probably done a few hundred of these over the last 6 years or so and it works very well. We put down 750 rwhp on our basic second pump in series. Many members here have this set up. I have never heard anyone here have catastrophic engine failure do to a a poorly designed 2nd pump approach. I'm not saying it's the best nor the only way but it works very well on our set ups.

I have a dual parallel set up on my car as a few other 1000 rwhp cars do here on 6speed.
Not discrediting any new finding at all but just stating known facts.

I have how ever had no less then 2 cars come through the shop, that the customer didnt know their inline pump was dead. This is the main reason we dont do the inline set up like this anymore, you wont know if 1 pump is weak or dying untill its too late.

 

Perhaps there is a way to meter this?

 

Ive had the secondary pump for about 3 yrs , first with my 18gs and now pushing my 30r's , i have never had an issue and quite frankly there are 100s of these setups around and i , personaly have not seen or heard of any issues, thing is i think that some people on here are trying to discredit this setup for some reason......

so its cool and all that you you guys did that the fishtank tests , but real world results speak for them selves .

 

From my first hand experience I would ALWAYS do dual parallel pumps!

Yes it costs more money but without proper fuel delivery under every situation you are asking for trouble. Why risk your motor for $2-3K extra for a parallel system.

If you want more and more power, do it right the first time and then forget about it. Thats my two cents

This is the safest solution period!
