Any bends after the volute blades will affect performance drastically. Unfortunately, Stillen didn't really take this into account even though it's pretty common in Vortech setups. It's actually quite a bit of work to install, since you have to remove the whole supercharger unit. Expect it to be a good 6 hour job if you do it yourself.
I'll post my results as soon as I get on the dyno. I will be running large injectors, a fuel return kit, and flex fuel though. Expect 500whp easily with the A2A kit alone (with either intake mod or pulley) and def more reasonable trq numbers.
Would love to follow the build/install, are you on IG? (kaostheory11). Are you the VERY first G37 to try this kit? If so I definitely would like to hear your results on fitment etc before I make the plunge!
Also are you a member of NortheastVQ group on FB? (if not its the best VQ group in the NE, hands down - join us!)
I rarely update my IG lol. I keep forgetting about it honestly. You can see what little I have @Kaoboybibimbop.
To my knowledge, I will be the first G37 with this kit. I informed a couple others who also intend to get the kit as soon as it releases, but I guess I'll be the guinea pig for now. I just sent in a request for NortheastVQ.
Cool, I will definitely add ya. Thanks for 'taking one for the team' as it were lol, sucks that you are the canary in the coal mine however you are definitely doing all us Stillen G owners a solid. I was literally on the cusp of pulling this kit off for a single or twin turbo, so this air to air news comes as a sigh of relief...hoping you have a problem free install and tune! Will stay tuned for the details.
Drew already got me. I was looking into TT as well honestly. There's very limited options for the X model though and troubleshooting is a much larger PITA.
I'm only really doing this because I'm fairly certain it will work. The setup is pretty straight forth and it makes sense because GTM/GAMMA runs A2A on their SC kit with more and safer gains (Rotrex SC setup is quite different though). I'm looking forward to seeing positive results though, since this kit has had such a bad rep in the past.
I got ahold of TOPGUNZ on The370z regarding the a2a kit, thanks again for the heads up! Waiting on your results on fitment, Milkcow500, godspeed and good luck man!
Kit just got sent out today. I'll post fitment pics next week sometime. I was speaking with Topgunz and we decided to go another route on how the piping is routed. Since, I'm going to be pulling off the supercharger to get the new filter on anyways, we decided to just open the supercharger and reclock the volute by 180 degrees. This way, you can just have a J pipe going straight down to the FMIC instead of having all these 90 degree bends.
Sorry guys, I got held up on the fuel return kit. Looks like I'm going to tune with just 93 for now and then do e85 sometime later. I'm expecting everything to be on in a few days.
To provide you guys with a update on my build I now have the SI supercharger, 2.95 in pulley 1000 cc injectors, 340 fuel pump, 50 millimeter tial blow off valve, Frozen boost intercooler upgrade, pmas mafs and am now making 450whp and 375 wtq. The tuner said he could have gotten a lot more out of it but turned it very conservatively on the timing due to the intake air temperatures with the upgrades to make it safe. I do not have an option for ECU Tech anywhere near where I live. So for now it is still on uprev. I have been driving it for about 2 weeks with this setup and driving the crap out of it and no problems. I am making 13 pounds of boost now and the power starts to swell up around 2200 RPM. Feels like a whole new car now and I love it. Maybe air to air sometime in the future to maximize my upgrades butt for now I would rather run a conservative tune to make sure I don't have issues.
Numbers look pretty good, but it's too bad you didn't go for EcuTek. For future reference, Seb at SpecialtyZ offers remote tuning btw, which is what I'll be doing.
Was your tuner taking IATs from the MAFs or did he add an extra sensor? You definitely have more room for power, since you can get 500whp+ with that much psi. I would keep it where it's at though, since you are still on W-A.
