I do know that to get it even close to right if you are going BOV route I added one washer and tightened it just in between hard and soft. My tuner still couldn't get it right. My a/f ratio would go crazy no matter what we did. So I ended up just leaving it full recirculating.

Your setup was pull through though and totally different. Your spring would be silver in material but it would have a touch of paint on top that is either pink, blue, or green.

Got ya. I figured it had something to do with the new setup y'all are doing. Whole new ballgame getting it set up right in that case.

I have a pink spring, It opens about a 1/4" at idle.

Even on the dyno it sounds really bad. i have mine rec. and under half load my car sounds like a helicopter. it flutters like crazy!

That sucks, are you keeping it on the car? I have the same one.

Evo. I think you were saying it needs to be tighter but I think its looser and this could be solved with a lighter spring. I think that because ive had flutter with a few cars/kits in the past and a lighter spring always fixed it. But this was with turbo kits so maybe with this centri setup its different.

Anyway, ive ordered the other two spring sizes so we will find out soon.

Injector, plugs, plates, supercharger rebuilt and clocked are all done. We ran into a problem with shimming the impeller, it's stuck on and not spinning freely from to much shim we believe. I decided to let a turbo shop adjust it to make sure it's right. Friday the car is going to the shop that is welding the piping, supercharger brace to the block and custom crash bar. They are starting with the pipe out of the supercharger so we can remove it as soon as they are done to get it adjusted.

Cant wait to see everything finished. Are you going with a big pipe for both MAFs or 2 pipes?

I'm going to talk to them Friday but the plan right now is to Y it into two 3" pipes but I'm going to hear what they say. The shop doing it works on my Audi TT and build all kinds of crazy Euro turbo cars and some sexy R-8 exhaust so I have faith in their fab guy. They have a AWD TT thats 850whp thats all custom built by them so they know what they are doing.

I think im dropping mine off at sashas, Tuesday.. next week.

Ill keep you guys updated.. But in all fairness, we wont know if it works until next year!

I've been without my car three weeks and I'm going crazy, I can't imaging waiting until next year.

I've been without my car almost 2 years now ... Long Story ... and I'm absolutely NUMB from it.

It was supposed to a SC'r impeller and power upgrade that would take only 2 weeks.
6 months later it was "Done" >>> "Quite Literally - DONE" >>> as in much smoke and oil and a blown motor.

Finally had to abandon the SC'r project after another year long wait with nothing getting done and go TT.

I did drive down to Maryland last week to check on progress though.
We are in the last phases before Dyno Day [hopefully that is]...:icon08:...

Oh crap man, that sucks. I hope it works out for you! Why is it taking so long? We are changing motors in my friend supercharged C5 Z06 for the 2nd time in 4 months this weekend. I can't imagine waiting that long.

Thanks for the sympathies !

Biggest reason for the delay is that the original shop doing the SC'r build bit off 'just a little more than they could chew' with the Z.

It was a 2 man operation and they did European cars and mostly bolt on upgrades...not custom fabrications...and with little to no experience with the 370.
After the motor blew [drove the car exactly 1 day] it [the motor] was sent to IPP in Texas <<< they did a great job.
It came back to N.J. last September - Just in time for the shop owner to take a 5 month hiatus.

So the car sat.

When he came back in March we realized that we weren't on the same page anymore - so I pulled the plug on the build and moved the car out of his shop and down to AAM in Maryland.
AAM has also been real good support wise and they are Nissan / Infiniti specialists.
But I have also upped the goals for power and performance as well.

The car is being converted to Flex Fuel with EcuTek tune.
AAM is developing a Twin Fuel Pump for the high HP thirsty Z's ...

That should be finished soon...and then it's Dyno Day.

Till then I be drivin' 55 :driving: in my G37

Dang that sucks, I was really hoping this was the direction I would take to keep things simple from a reputable source. Sorry it will take so long for your outcome. Positive side is this venture has created lots of interest, starting other builds! :tiphat:
