I'm still confused how you ran out of 1000IDs at less than 550whp. Some of the turbo guys are pushing past 700who on 1000IDs.

My tuner said it is the pump that can't keep up.

Does the walbro E85 450 fit in the pump assembly? Anyone have one in?

Deep into the 12's AFR up top past 7K.....:eek: Isn't that a bit lean for F.I. and risky or is it OK to be at with E85? Are u on UpRev or EcuTek?

***I ask about E85 as its not available where I am from...Highest grade pump is 91 and highest grade available here is MS109 from VP.

E85's resistance to knock is insane. It isn't ideal but we didn't pick up any knock at all. You probably can't do that with pump gas.

You will have plenty of fuel with 91. E85 requires about 30% more than pump gas.

And im on Uprev. My tuner told me to also switch to Ecutek..lol..

Stillen SC kit due to arrive next Tuesday! TopgunZ, is my kit still on track for early June?

Update...so Seb says the cruising logs look great. We are troubleshooting an issue where the transmission gets hung up and doesn't want to shift in 3rd or 4th gear between 3-4k rpm.

Yes sir. :tup:

Could we just cut one of these puppies into the charge pipe and keep the water to air setup alive?

frozenboost seems to be all about water to air intercoolers

Will never fit plus your mafs will still be pre charger.

Sawzall a hole in the hood and weld a hood scoop on! I thought this was uhmareca! Then put a gol dern maf sensor behind it. Bewhitey water to air kit! comes with 100mph duct tape

(that would probably be a fun project)

Update- So today we were still detecting knock. Seb sent me a tune with only 17 deg advanced WOT and it still knocked. He said that this pretty much confirmed that it was detecting false knock. He said there is absolutely no way it would be knocking on e85 and only 17 deg advanced. He plans on desensitizing my knock sensor and we will try again. Seb said this sometimes happens to supercharged Zs that he has tuned because the blower is attached to the engine and it detects its vibration. On a positive note, I did hit 11 psi today!

Yeah Seb said he has never seen my issue. With the changed torque values in the tune the transmission would get hung up between 3-4k rpms and wouldn't shift. He changed the torque values back to stock and it shifts fine.

I wonder if he was going off of my built trans torque values on yours. Is your stock? At first mine was doing the exact same thing and would take around 15-20 seconds to shift. I would have to let off the pedal a little and it would shift. He has it dialed in perfect now.

That's exactly what mine is doing. It only does it in 3rd or 4th gear

Oh and yes it is stock.

Strange. Ive had dozens of dyno tuning pulls and never picked up knock.

Is this all still on the same tank of gas? Id almost want to drain It and get some Ethanol at a different station.

Could it be the different piping that Evan is running in his kit? Topz...weren't u using that same.kit in your car before?

im still trying to combat this flutter.

Im kinda stumped, Does the spring need to be a lot stiffer to stop the flutter, or does it have to be a lighter spring to allow it to stay opened.

No, I never ran that pipe since I am only able to MAF tune.

The tighter the spring, the more flutter you will get. You basically just want enough spring pressure so that it stays shut on boost. The lightest spring will have the least amount of resistance to vacuum therefore getting pulled up and away from the pipe.

You get flutter when you are part throttle right? That's because you are going from 18in/hg of vac to say 5. The spring pushes down towards the pipe but the sc is still blowing air out of it at 5in/hg. So it pushes then pulls then pushes etc....

I had the lightest spring in my Turbosmart dual port and still trimmed it down by like 1 and a half coils. It worked perfect. Problem was that it cant purge enough air when you let off the throttle at 7K. It can flow maybe 300cfm when it should be blowing out at least double that.

The Tial QRJ is the way to go. It has very minimal flutter but is very loud due to how much air it can let out of the system. Just put a hose from the outlet to inside of the engine bay somewhere and it should be good.

Hey topz, I just bought that adaptor from ebay, im about to order the Tail BPV, do I need the 1.5 or 3.0 psi spring.

thanks brother.

1.5

Thanks! got mine coming.

Going to put my timing cover back on tonight, hopefully I fixed my low oil pressure issue.

dyno in a few weeks!

Well Seb has got the transmission shifting now. Waiting to see what he wants to do now.

Everything with me went good today. Got some good logs with no CEL flashing. I cant believe how strong the car feels. Really the first time I was able to go to redline without it pulling timing.

Awesome! Yeah, I noticed mine after around 5500rpm really starts to put you into the seat. That's usually about when my wife grabs onto the O'shitt handles. :tup:

Gosh, seeing all of you guys doing this makes me want to jump into it too! I've just been waiting three months on my car to get out of the shop and still working on issues:/.. I will be looking to purchase this kit diffenitly this year though!

Is there an advantage of using this kit vs. say buying a Fast Intentions Turbo kit? Looks like it might potentially be a little less costly, but seems like there were an awful lot of steps and ongoing tuning required to get things dialed in. Is perhaps the hp and torque curve being more linear due to use of a sc vs a turbo another advantage?

The FI kit is tried and tested as with the Air-2-Air setup we've yet to see any real miles with the kit up and running. I hope the best for all the guys making the Air-2-Air change as it corrects most of the problems with the original Stillen design but we need more miles driven to know how well it works.

Other than that it depends on what you are looking for in performance. A SC car responds completely differently than a turboed car.

I only have about 1400 miles of smiling fun on my Air to Air kit. Not sure where the threshold for "its proven" is but I cant see anything going wrong at this point.

However, yes I am the only one who really has time on it.

Turbo's will be a more torquey and you can feel it kick in where the supercharger basically feels like the stock car with twice the power.

Your right though, there were a lot of steps that were needed to dial it in. That's what is needed when you change something on anything. Before I decided to produce these for others. I basically threw it on in my garage in a couple of weeks, tuned it, and drove it for six months at almost 500whp. Trying to get it mass produced is different.

Jwillis had a terrible experience because he had a terrible shop trying to do something that hadn't been done before.

Once the two kits that I have sold, one for the 370z and one for the G37, are tuned and ready to go I will make an "official" thread to purchase these kits from with details on what you get and a complete set of work instructions so you can see how it goes on.

It took me a couple months to change mine and I have about 200 miles on it so far. I'm still in the tuning process through ecutek. It's a remote tuning process by Seb at Specialty Z, so it takes a little longer to get everything dialed in. The car feels awsome and it's nice to see the intake temps at 10-20 over ambient and for the ecu to read them accurately. Anyone who has the Stillen Kit or wants it should do this.

Yes, remote tuning is a very long process. I just take mine in and its done in 3 hours. If your only option is a remote tune through Sebs then it is what it is and I have heard nothing but great things from his knowledge.

Looking forward to getting this done on my car soon! :excited:

Thanks guys! Great feedback! I'll continue to monitor for long term results and the official thread!

Coming to the final stretches of my tune. Here is a quick clip of a full throttle pull through 1st and 2nd and 3/4 throttle through 3rd and 4th. The road I was on was a little sketchy so I let out a little but it is pulling extremely hard. Note I have M/T ET Street 2's. Hit right under 10 psi 1st and 2nd so not sure what I will hit top of 4th. I have seen 11 psi so far in 3rd just not this pull. Probably wont get an accurate max psi until I hop on the dyno. Seb has my AFR WOT low 12's. Said he might go a little more rich and call it good. My timing is around 22 deg advanced as of now.

You were ripping through those gears pretty quick! And that tial is sounding good on there.

That is what I'm talking about!

Coming off this similar platform but in the conventional way, I must say this video looks very promising for the up coming future builds going A2A! :tiphat:

I LOL how you just left it in Drive Mode and passed on the paddle shifters, Let's Just Roll... GT-R Style :driving:

StillenZ34.....Looks like ur progressing nicely and putting some good power dwn based on the way ur holding that steering wheel and the overall sound and look of ur car as it launches....is th at run on E85 or 93?

E85
