Thinking about going big turbo? Spool Data.

This is exactly what we need, as consumers -- actual comparative data.

I agree!

Also not trying to get too far off subject. How have the ford racing cams performed in the upper RPM range? Any results seen with these cams and either turbo listed?

I remember MAP testing them and they did not make any more power. At least that is what I remember. Back when they were testing a set up in stages. Stock head, then ported head, then ported head with Ford Racing cams. :shrug:

The Ford Racing camshafts are useless. Someone needs to come up with some camshafts for this thing.

Correct, I did the testing on them and they were worth 4 inconsistent HP and no additional torque.

The Full-Race Twin Scroll 7163EFR seems impressive for its size, spools fast .
The Vargus 2 seems like something holding it back from fast spool, at least from a turbo size view, its one of smallest ?
It could also be not loading engine low enough on dyno to i guess .

It seems to be spooling faster than every kit except the 7163 which is on 100 octane. It's clearly flowing more than the 7163 as its holding more power and tq to redline on simple E30 mix. This info is extremely telling, I appreciate you posting it Adam. It proves for a turbo that is flowing as much or more than the bigger MAP kits, it's spooling better, and costs less than half, basically almost a 3rd, it's pretty much a no brainer for someone looking to make 500WHP on a budget, or keep the car looking stealthy. Once we get some 100 octane, race gas or 100% E85 in the car we can really see what the turbo will do! Very happy with how our stage 2 came out, and is performing! Looking forward to more testing!

I wasn't trying to be funny or anything, it was honest question .
I was looking at the TQ slope, and it "seemed" to me to be more gradual , I was thinking closer to stock slope , but I guess i was off on what flow it handles as the power is there , especially on top end .
I guess doing ball bearing is out for future or could stock sized housing handle size of BB (I am assuming there bigger than normal sleeve type )?

Also its hard to judge as we don't know boost each one was running .

Sorry! Totally misread that as I was driving. I changed my response to reflect that! My apologies!

So...i like the full race until around 5k, takes a dive like stock. Why?

 

[VargasTurboTech]

That's back pressure coming up, turbo can't flow up top with that twin scroll adapter / manifold. The 7163 is a very similar sized turbo to our stage 2 As far as wheels. But as you can see the turbine side is restricive up top, causing power to drop off

I have been on the fence on which turbo to buy and/or buy a methanol injection kit for the longest.
So if I was to put all my cards on the table..
I already have the MAP intercooler, Airaid intake, Catless turbo back exhaust, SCT X4 custom tune and my car puts down 315hp and 385 tq as is...
Which turbo will get me to 420 or closest to that number on 91 Octane? Is that possible to answer?
I realize the Vargas put down 380 on 93 octane on limited tuning and the MAP turbo kit lists the journal shaft kit but the ball bearing is an option, will that put down more power on just 91 octane just by going BBearing? I will NOT be running E30, that's out of the question for me. So I want to see what can get me close to the 420- 430hp mark on pump gas, again if its even possible on 91.
So I guess the question is, ON PUMP GAS, which turbo will make more power?
My car is daily driver and sees track time (drag strip) about once a month.

Adam answered that question just today. Maybe in another thread. He said it is because the stock head and cams are to restrictive.

On 91oct, none of them. On 91oct and methanol injection any of them. You will want to pick which one you prefer for spool and the overall look of the kit.

Ball Bearing will only get you faster spool, it wouldn't get you any additional power as the wheels are still the same. There is less restriction but not enough to warrant additional power.

Your limitation isn't going to be the turbo, your limitation on power is going to be the fuel. There is simply not enough octane to produce the power you are looking for.

Thank you!

So in your opinion then Adam, or actually in your experience with dyno tuning these compressors, which one made more power on pump gas and does that equate to making more power once your meth kit is added to the equation?
I honestly don't have a preference on looks of the kit, so Im not looking to pick a turbo kit based on "stealthyness" of it. Im more into making really good power safely. I want to get to the point of making top power on stock internals and that is my goal. along with longevity of the engine/turbo ofcourse.
Thanks for answering these questions. Im trying to make a decisions but Im trying to get most info as I can on everything.
On a side note: I saw a video of the MAP turbo and that thing sounded amazing spooling.. does that Vargas sound similar?
