The comparisons were inevitable at some point, so Terry sent me a single graph and we did a quick overlay, its very interesting to see how close these are, Stage 2+ has a decided advantage from take off until 5300-5500 rpm then the single starts to pull away slightly, both these sets up are not maxed and I would expect they both more in them, I expect Staged 2+ to have about 675 when fully maxed on destroy mode, and the single to have a little more. Things are heating up in the N54 world...

Two graphs, one for RPM and one for Speed, the speed graph shows a pretty close race..

Hi Tony,

I've been meaning to ask this question. So would you say at 600whp daily driven e85, the turbos would be in their efficiency range?

I get that max would be 675 but for me 550-600 would be my target to get the most out of this engine.

Thanks.

I reckon the stage 2 twins will take out any singles on a street race anytime... Look at the way its making the torque! Amazing!

Running 550-600 they should be in a good range, no where near maxed, obviously the harder you push them the harder they are going to have to work, we will know more when I get a shaft speed sensor on them, but 550-600 I know will be a good place for them based off the backpressure we are seeing at much higher levels

We're definitely gonna put all this to the test at the upcoming events. N54s are gonna dominate the BMW shoot outs(other than hpf e46 ofcourse), and that's freaking awesome!

these are exciting and disappointing times.....for those (myself included) who purchased a singles turbo kit. Now stock frames are going to put the singles to the test.

Keep in mind those numbers were put down with the dual hpfp shotgun kit. Performance will not be nearly as good with 91 or 93 octane. The singles will start showing much better numbers as well once they get the dual hpfp or port fuel addition. Plus, the singles will own the top end. So, as long as it's not a short race, the twins may get the jump, but the single will likely real it in. Besides, you gotta have traction to make the car move

It also looks like he used GTI's graph which is a VM top mount with stock exhaust. Ando made 17psi @ 3366 with an auto. I'd like to see him use that graph

Can't wait to see your next build!!

I used the graph as I was asked to use as being the most comparable. Terry made a 5852 graph comparison in the other thread. Why are you even interested in anything to do with our products, all you seem to like to do is hate, talk trash about us, and our products. So why stay in our threads?

[Tony@vargasturbotech]

As you can see our set up makes buying a single turbo kit and using a 5862 a very expensive way to make less power everywhere.

[Bme30]

Buying the 58mm is now a waste.

[E92oreo]

Any comparisons against a 6262? Or 6466... These twins sound amazing

I was making a serious statement,I was not bashing that time. I would have said the same thing to anyone's thread. But the fact it said it was compared to a certain kit using only one graph is where I challenged it. Anyone can take the worst spooling stg2s and compare it to a 86mm single and say "look!" just to sell a point

Is that 5862 running 100% e85 and maxing out the injectors? If not, the 5862 may still make more power...

Edit: Regardless, these stock frame twins are impressive and make some nasty power.

No idea what its running, its Terrys car that he used to break the 60-130 record, that he has been fine tuning for months, my guess he has it pretty much dialed in. For the people asking for graphs against other bigger turbos, lots of graphs are out there, feee free to overlay them, expect much bigger differences down low in our favor and much bigger difference up top in their favor. I did overlay our 725 stage 3 prototype run against the 6455 and this set up, the twins look pretty good

If I read correctly that is an automatic setup running 27psi, 5 degrees of advance midrange, with a race gas mix. You're comparing with 100% E85, more timing, no air filters, manual trans setup. They can crank the timing up to match yours when they upgrade the fuel pump.

The single turbo kit may be $3-4k more than modified OEM twins but keep in mind it is rock solid reliable vs. modified twins that have proven questionable to say the least.

No Mike, I am not comparing them, Terry asked for my file and he compared them, see the branding on the graphs. As for set ups, were running 28 psi TO 24.5 psi at redline, 10 degrees or timing, and I am 100% positive we are GIVING up power by running no intakes ingesting 400+ degree air, (plus please explain how no intakes would have any bearing on a single kit that has stock intakes removed as well, but is ingesting cold air from the top of the engine bay). This is the also the car terry wants to change the turbo our turbine housing out on because he feels it is maxed out as boost is auto tapering at redline even with only 27 psi, but you say there is a lot more left? So just a quick recap, were running less boost, minimally more timing, dealing with a lean condition so we cant turn anything else up, yet making more power everywhere for $4K less, but you want to say this comparison not made by us is invalid because why? My argument, buying a single turbo kit and putting a 58MM turbo on it with these turbos on the market, is paying twice as much money for less power everywhere is 100% accurate. But you are always trying to put a negative spin on everything we do, so not surprising. Cheers bud...

[Evil///M]

Please explain how modified twins are 'questionable' Mike..

[Bme30]

No one knows the reliability just yet. I'm sure they will be just fine....but maybe that is where mike is coming from.

Twins is the way to go for stock response with massive power lurking within

[jayzF30]

I would love to see these run some 60-130mph runs or 1/4 mile or anything that puts them under a lot of stress to see how they last in this configuration.
