SignUp Now!what single pump do you recommend the OP get?
^ You obviously have no idea what kind of person nick is.
The Red Armstrong XP.
My Walbro mght be out. Which pump to get now? I want to stay with a single pump.
Out of curiosity...do you have to upgrade the OE return line if you install anything larger than a 255 lph pump? I thought I read that somewhere.
So no mods to fuel line with DW pump?
I installed a DW pump and I couldn't get my idle pressure below 50. After installing a new return line I was able to get it down to where it needed to be.
^ @ DMM, no.
I had to run a bigger FPR and return line to get my Deatschwerks idle pressure down.
You won't have to change it,but you might have to modify it.
If you run E85,your motor will use 30% more fuel at idle,so you wouldn't need to modify or replace the return line.
Since you use 30% more fuel throughout the power band,this single pump will run out of steam sooner.
So you want him to get a RA XP or a double pumper? you changing your mind on what he should get?
aimed directly at Nick, you're going to catch flack. Nick's pretty respected on the board as having good integrity and being fair and honest with not only the people who pay him, but also the people who DON'T pay him and are just looking for advice.Why do you recommend the DW? Because you sell it. You'll defend it until gasoline is coming out the crankcase vents,then you'll advertise that it comes with a waterfall attachment at no extra charge. It's human nature.
The first public comment on too much pressure with a DW pump was from Eric at Turbo Tweak. Shortly after his post we met in NC in May, 2011 at Richard Clark's event.
The 3 of us had a discussion about this issue, and RC showed us different stock return lines and how much the opening can vary in size. In the testing RC did with the DW pump, it provided great results and proper pressure if the return lines/fittings are not on the small side of the tolerance.
just because he has a T66 and is looking at E85 possibly down the road doesn't mean he will be at the limit of a single pump.
Should we also bring up that reds pump, is not built to handle E85.
Im also pointing out that talking about fuel heating is a bunch of BS for our TR as this has never become a issue before and you must agree because you don't want to talk about it anymore.
ADD ? OCD ?? WTF !
heated fuel provided better performance.
I hate to add giberish to a topic I know nothing about, but can someone who was at Richard's place just tell us what the return line measurement should be that would allow proper fuel flow so we don't have to mod it?
Wow, excellent feedback! It seems I might end up changing out the return line based on the DW, Aero-Stealth, or Walbro 400 pumps. The DW pump does look good indeed, but further investigation also includes the Stealth and Walbro 400 pumps. I know that 30 psi would be the max boost used, so a pump that delivers the most flow at the lowest draw at 70psi would be the pump I would like to get. I could use some help here. Thanks.
Yes, ME! at the 1000 ft mark pump died suddenly.Do you know anyone or have you heard of anyone who,while in the middle of a quarter mile pass,has had there single pump turn off like a light switch. No.
What happens,in reality,is that the number one piston explodes and causes your whole engine to self destruct because you trusted a product that was 3 months old, purchased based on its performance advertisments as well as previous products made by a company known for its quality. I am refering to the Walbro recall F20000169 pump fiasco that caused nightmares across the car world.What happens,in reality,is that the pump gets less efficient and the WOT fuel pressure starts to fall over time. If you monitor well,you catch it. If you don't it can bite you.
