Description

Spool - Helix HPFP Overdrive Unit – BMW 135i / 335i E8x / E9x N54 / N55De Spool Performance Helix HPFP Overdrive Unit is ontwikkeld voor BMW N54 en vroege N55 motoren om de capaciteit van de originele high pressure fuel pump (HPFP) aanzienlijk te verhogen. Door de HPFP sneller te laten draaien, wordt het verplaatste brandstofvolume verhoogd, waardoor drukval bij hogere vermogens wordt voorkomen. Dit biedt een effectieve oplossing voor high power builds zonder de complexiteit van extra port injection systemen. Voordelen

Veelgestelde vragen

Waarom is een overdrive unit nodig?
Bij hogere vermogens kan de OEM HPFP niet snel genoeg brandstof leveren, wat leidt tot drukverlies. De Helix verhoogt de pompsnelheid en lost dit probleem op.

Is extra brandstofaanpassing nodig?
Ja. Stage 3 low-pressure fuel pump is vereist

Wat is het verschil tussen Helix en Helix Xtreme?
• Helix: geschikt tot 600 whp op E85
• Helix Xtreme: hogere ondersteuning tot 750+ whp op E85

Is dit product getest op duurzaamheid?
Ja, de Helix is volledig getest. De Helix Xtreme bevindt zich in de laatste fase van duurzaamheidstests.

Garbage
Size: 6FT*6FT, Color: Black
This product is absolute garbage! It literally took all day to put it together and if the air conditioning blows on it the wrong way than the whole thing top over and it falls apart. It’s not made of quality material and is very flimsy. The only reason I’m not returning it is because it’s too difficult to put together and I don’t wanna spend that much time trying to take it apart. Do not buy this!

Cheap
Size: 6FT*6FT, Color: Black
They serve their purpose as long as you leve them in one place and not moving them around and they're kinda flimsy and some of the velcros are cut too short and can't stay closed

Worth the investment
Size: 1 Panel, Size: 1 Panel
I had to order this in an emergency. To put it in brief words, I live in a two level studio unit. My bedroom TV fell backwards off the bureau accidentally and down the stairs to its demise. Putting this together was no problem, instructions were thorough and easy. It came with several bars that connected together smoothly and an Allen key for the brackets and screws for the feet. I did one less horizontal bar on top and bottom so it could fit, which was great because with all of them on it was too long. However I ran into the difficulty of the horizontal bars popping out of the brackets during the last stages, but eventually got it done. I was also looking for a specific type of divider where I could adjust the feet so I could tuck it in between the dresser and banister. Glad I made this purchase.

You Get What You Pay For! A Piece Of Junk!
Size: 1 Panel
Flimsy and a piece of junk. Don’t waste your money. Assembly is a pain because it is so flimsy. Divider is thin. You can see right through it. Very wobbly.
