Pumaspeed X57/R/RS

[gtx3076]

Plenty of mk7 gtis with over 400whp on straight 93.

So much buyer's remorse over here.

I have a x57rs in my garage right now. I'll do some testing and get back with my results once my build is drivable again. I'm figuring that I've done everything I can to supply adequate fuel and air so if I hit low numbers I know pumaspeed is lying about their numbers.

IM just hoping you DO NOT have the coolant connection sealing issue others have encountered!

If you have aux and whatnot I think you'll be fine. I believe they inflated their numbers on the stock fuel system.

I'll be getting a bravo alpha fuel pump and running perons 4 port and eventually try running straight e85

Also, I hope not as well. Tim pownall told me they fixed those problems and that it was a machine error but it doesn't mean shit if I install it and it doesn't work. I've also heard stories of white smoke and I think it's the same issue, coolant leaking

Just remember that e85 can vary in its purity which legally can be between 51% to 83%. This is why mixing is better as you have more control.

I'll keep that in mind. I'll definitely need an ethanol gauge since that's the case.

Get the Fuelit Bluetooth one its was like $300. Then get the Fuelit app and just pull the app. up on your phone to check what's coming through the line and it Temp. I have it and love it!

Well Jason made one that actually looks really well thought out. It sits in the unusable cubby by the shifter below air control

That is also a great option!

Mixing is in no way better. Just test the pump you regularly fill up with once a month and you will be fine. The ecu can compensate for slight deviations. Your not gonna get large fluctuations at the same pump or ussually even in the same area.

I love my buddy's mk7 and it's a much nicer car then my fist but in reality it isn't as fun to drive. If I didn't get a fist it would have been a dct mk7. I've seen guys making 420whp on 93 with the stock fuel system.

This is not TRUE about filling up at the same pump....I have seen it fluctuate a lot from the same pump. Bringing a tester to the gas station and having to dick around with the Tube tester...spilling...smelling like e85. No thanks ill just have a gauge that's more precise. I spoken with Numerous tuners about running straight e85 and I've gotten the same answer...NOT WORTH IT. But then again WTF do I know.

Of the pumps ive used ive never had any of them test under e80, even in the winter. Not having to mix is really convenient. Most people just have an e85 tune for summer and e55 tune for winter as alot of places shift into winter blends.

This was a few revisions in on the x57rs, before I removed it.
93 octane with single port aux.

276 with aux seems... disappointing (but I know it's not final).

Jason what was the problem too little air, spark or fuel to make any more power?

It leaked coolant like a sieve !

This seems really low for 28psi. S280 is making more with 28psi tapering to 24psi past 5800 before my aux was turned on. What Kind of timing were running. The AFR doesnt seem fat.
