Indeed. That's next on the list. I popped the hatch and it looks like the tails come off easy without removing interior panels. We shall soon find out. Going to the track on Friday ... 13.7 @ 125 MPH here I come.

Might do some small stuff down the road, but nothing planned at the moment.

Nope, had a 300+ mile cruise through some windy hill country roads and managed to not blow it up. I was datalogging boost and knock values the whole way and they stayed relatively normal. Car is pushing about 300whp / 320wtq. running 20 lbs. of boost. It should run a mid 12 at 108 - 109 MPH...

Turboback is installed as of tonight. Car cruise tomorrow morning.

Muffler section is in along with the gaskets. Now to install it ... damn cold ass weather.

Good thing I got a 2011.

Intake side, yes, exhaust side ... ehhh ... they get cheap on stuff with the exhaust and sometimes it doesn't always mean efficiency. My STI has a 2.5" mandrel bent exhaust on it from the factory. An exhaust does virtually nothing but make noise on these cars. The downpipe on the other hand...

That's what I was thinking ... gonna take alot of juice to get that fat truck down the road alongside a ZX14!

Damn, how much power is in that truck?! ...

Resonators will increase the power over specific points in the curve. Removing them causes resonance in the intake at certain node points (RPM wise) and that causes improper MAF resolution and other small issues. The name of the game in an intake is reducing flow loss. OEM intakes incorporate...

Downpipe and midpipe are in, waiting on the muffler section. I think UPS lost it.

That must be GM's latest race car, the ZL2 ... it's the next evolution in lightweight race trim.

2 weeks ... tops. :ohnoes: After the exhaust there's not much to do to them that's not outlandish. Might put a subwoofer in it and do some cosmetic stuff. The M3 is gonna be beast though ... it must be so.

WsrYvQOeLE4 Same setup on the same car.

So the sound of a H4 have grown on me ... to the point that I'm finally putting a downpipe and exhaust on my STI and going to stage II. Generally this puts out about 300whp / 320wtq. ... which should be FUN for an AWD car. Downpipe came in today, waiting on the exhaust and gaskets. Also...

The current Z06 has more performance than 99.9% of the drivers on the road can handle. That might have something to do with it also.

I'll take a Miata with an F20C motor in it.

Power isn't enough to be fast these days ... my Subaru had 305 HP and its much slower than a stock LS1 Camaro. Power delivery and how it's translated to the ground counts for a lot! Especially when you get up above 400 - 500 HP. Regardless, these cars are beasts! The amount of performance you...

I wonder where GM is hiding the lead ingots in that ZL1 ... I mean c'mon ... over 4000 lbs?! There's absolutely no reason why a Camaro should weigh 1000 lbs. more than the Corvette. I have an AWD 5-Dr. Turbocharged car and it's 800 lbs. less than the Camaro, with another drive axle and 13"...

So after driving my STI ... gonna reconsider an STI Sedan? :jester:

They are raising the fuel pressure to accommodate the lack of flow in the injector. Fortunately for you, running a bigger turbocharger means you'll run more efficiently and won't need as much fuel to make the same power as the OEM one. You should be making about 300whp at around 14 - 18 lbs...

300 HP at the engine is doable, 300whp the injectors are going to be pushing over 100% duty cycle. My STI has 565cc injectors to support the factory 305 HP @ engine, and at 18 lbs. of boost my duty cycles are already pushing over 80% ... but that's closer to 350 HP now.

Those injectors are too small for that kind of power. They'd support about 260 - 270whp before they run beyond what you want for a duty cycle. That's why he's running higher fuel pressure, to boost them close enough to support it. I'd swap them for some 50 - 72 lb. injectors if you plan on...

I would buy an Aeromotive regulator and properly plumb it in with a large return feed. What sort of power are you going for, what size is the turbo, and how much boost pressure are you going to run?
