Some blower piping upgrades
I am still rocking the same setup more or less - but did redo my intake and discharge piping from what was still the basic kit, and re-piped the meth injection scheme - here's a few pics. Did get to try out aluminum brazing to get the bypass inlet fitting welded onto the 4" elbow, which went ok once I got enough heat into it. Also built a stainless 3-1/2" discharge tube and had that and the Vortech elbow ceramic coated.

Thanks for the compliment! Both ways are effective. If nitrous was somewhat cheaper, I would probably have that, too. Without an intercooler, I show high IATs, although I am spraying most of the meth after the sensor at the throttle body, so the engine is not really seeing hot air. I still think the nitrous would help that out a bit if I sprayed into the discharge tube. Really, now the issue is just what to do about the sensor reporting highish temps to the pcm and what effects that really has. I can always do something to fool it. I am also injecting some meth/water right at the blower discharge which has to be helping some, but not sure how much (it is a small injector). Some guys spray into the blower, but I am undecided about that. Maybe I should just get busy and figure out how to get an intercooler/aftercooler in there without hacking up the car.

Thanks - I used to have two nozzles at staggered positions in the first elbow, but when I redid everything I put them in the spot that is most advised by the 'experts'. I could probably have squeezed them in a little ahead of where they are and ahead of the sensor, but I can still play around with the sizes and the third nozzle that is a little below the bypass to see if that helps, otherwise I can do something different with the sensor or the settings in the pcm. I think that aluminum intake elbow always heat soaks that sensor anyway. it is a little better since I got it coated.

Thanks, I am hoping the 4" intake, big MAF, and giant filter nets me a less restrictive intake and maybe a couple more pounds of boost. I am seeing 15# at moderate rpms and haven't really revved it high enough to see what I'll get. I've been re-tuning it for the larger MAF and different meth injection which has changed the tune more than I thought it would and has been a little hard to cram in. The other thing is that last summer, I rebuilt the A4 transmission, and had to retune that to last longer than the one before it, since I believe there are things in the stock tune that contributed to its demise, like violent down shifting into second on WOT kickdown, etc. So I still have to get all of it wringed out to see if I did any good. And I need to get to the track to see if I can get into the 10s with this - last time it went 11.1 124-126 on the DRs with not enough fuel delivery (fell flat on a couple of the burnouts and went lean at the top end of the track - meth/water injection probably saved it). It also had the fuel system redone since then and a bigger bottom pulley. I've been so busy that I don't know when I'll get back there...
As far as less attractive setups - I've seen very many of those that are way faster than me - however, I spend some time at car shows, so that accounts for some of the bling under the hood. I've been winning a few, too, keeping the faith for the 4th gen crowd - most of the LT1 cars I see are either really nice or raggedy with high miles. I think there are less of them around.

Yeah but the divider in the Vortech elbow causes issues with meth. I ran mine with a nitrous plate behind the TB without any problems. If nothing else you can have the meth relay short the IAT with a resistor to whatever temp you want. LS1 cars do it with nitrous all the time.
