Here is mine, a 90 degree day for the dyno so more will be on the table when it's cooler out. I lost a pound of boost with my long tube headers and cold air intake as expected. I am satisfied for now, another 100 to the wheels is easy but I like the mileage and performance the way it is today.
Between 3500 and 5500 rpm, the car is crazy fast.

I have been reading this thread and have a question.
If a car makes 8lbs of boost from a twin turbo set up and the same car has 8lbs of boost from a maggie set up why does the twin turbo make more hp?
What am i missing?
Isnt 8psi 8 psi?
Thanks in advance.
Great thread by the way!

Great thread by the way!
Efficiency of drive....

Hypothetical numbers....

Maggie ... 8 lbs of boost.... makes 150 hp..... It take s 75 of those HP just to run the maggie so a net gain of 75 hp....

Turbos.... 8 lbs of boost.... makes 150 hp... takes 30 of those hp to run the turbos.... so a net gain of 120 hp.....

Again, these are hypothetical numbers.... but belt driven blowers are considered to be roughly 50 % efficient...

Turbos 80-90 % efficient... and these are arguable numbers...

This is all dependent on quality of build, properly matched components... etc.... Putting a big rump rump cam on a FI (forced induction) build is not necessarily the way to gain efficiency... Using shorties headers are not going to help engine breathing much more efficient.... as using factory manifolds with turbos is not the best route....

It's all about properly matching quality components.

Don't forget, its also about the air you flow. 8 psi on a small turbo or small centri is not going to push as much air as a bigger turbo or centri at the same boost.

To add to this....

My car for example.... again hypothetical numbers...

Small turbos, spool immediately, make boost way out on the edge of the boost efficiency map... create huge amounts of iat heat.... due to overspinning and working like crazy to make boost....

Now, big turbos, less boost, more efficient area of the boost map... less iat heat creation.... more boost efficiency... so more power with less overall boost....

Think of a little fan in a big room, or a big fan in a big room.... which one works harder and which one is more efficient....

I'm liking those base AGP Turbo numbers above.
Just visited their website, $6700 for this twin turbo kit is not too bad at all, in light of that dyno chart.

$6700 is for the tuner kit.You'll need some injectors and fuel pump upgrade.
Great kit.

Do 1LE owners like myself still need a fuel pump upgrade?
I believe the 1LE models come with the Zl1 fuel pump.

Here my preliminary results for 2013.

We've been stuck with a 3.6 pulley due to belt slip. Next year we'll try again with an 8-rib drive and pulley down given we're not running out of octane.

675rwhp / 676ft-lbs of torque
12.6lbs of boost
no meth

Cam change and AGP twins (S261) vs Ysi with centri blower cam. Bold green and blue lines are turbo results in 5th gear. Finer blue and green lines are Ysi in 4th gear.

Man, practically everyone on this board with AGP TT setups, are posting up some amazing numbers in proportion to the boost used.

You got cammed (est +35hp); I didn't figure I'd need that route just yet (likely our difference). You can see my boost taper off as I run up the RPMs on the unloaded dyno. The tuner figures a loss of 35-40rwhp there. I'd like to run on a loaded dyno for snitz and giggles.
