nice man! do you have an A/F and KW on same graph print-out? would love to compare

the dyno mine got done on 370z with bolt-ons only got 176KW lol, so guessing mine is around similar mark, I'll go to a couple dyno days to see which dyno's read what :D not too worried about the numbers atm, boost level is reaching 9psi and it hammers!

here is my stock so your about the same, enjoy the purrrrrrrrrr

Your AFR seems a little too up and down. The numbers are close to where they should be. I'd be more concerned with the power you made but if you couldn't mess with the timing then it is understandable. You should hit 300+ KW with your setup. Have your tuner clean up the AFR a bit when you go back for your next tune along with the timing.

I like that now it froze to cause the problem when the car does not go out in rain or snow and sits in a climate control garage all winter. Plus the thing blew while driving 3 weeks in to summer and the temp was 80-90s. Good laugh Team Stillen

We never said it froze, I just said to watch out for that as that could be a possible cause for such damage. No need to get defensive. I've never seen (in person or in pictures) your insulated/climate controlled garage and you have not sent in your IC for evaluation so all I can do is speculate just as you have.

where should we be aiming for AFR wise? I would have thought tune would have been super clean, they are a pro uprev dealer. I see my peak number flatten out and the AFR come from around 11.7-11.8 to 13. there is a lot of unburnt fuel I think it could go a little leaner.. I know safe is good but kind of looks to be quite rich.

also what sort of timing should we roughly be looking at? I can ask what it's at or any graphs of it, forgot to ask about it. Any help would be appreciative and I can point them in the right direction and we can do some testing to make sure there's no detonation.

It's currently middle of winter here, so out and about most places where I am, gets down to 0ish-10degrees celcius while nighttime, would you also advise a sort of summer tune? pull back some of the timing during the hotter weather?

Also from the speed on dyno sheets, looks to be 3rd gear pulls, wouldn't 4th be better in a 6 speed?

Next up is potential E85..

would I see full benefit from it considering the kit as it is, is pretty maxed out considering the charge pipe/maf's etc..?

I haven't seen anyone else with the stillen kit on E85

My car has always ha 4th gear pulls.

You would probably be the first known on the forum to do e85 for the Stillen kit.
Waiting on final results of a GTM SC kit to see any potential in general for the 370z with SC. I would say you might see more power increase as you can push the car a bit more while keeping it in a safe range. Though you just did your install and I would say to make the jump to e85 would require some new fuel parts you just installed.

yeah, is there someone doing E85 on the GTM SC? got the link to the build?

won't be doing it right away, probably after april next year (going away overseas holiday for couple weeks). I was going to do it straight up with the stillen install, but the difference between the tuner kit (minus fuel pump/injectors) and the full kit was couple hundred, couldn't justify it. Just figured I'd install this for now, tune it get used to the added power then step up later down the track, would possibly still be able to sell the fuel pump/injectors cheap to someone local here in Aus by then.

also not to mention how much of a pain it would be to get to the injectors again haha, stillen manifold is a bitch to put on.

Here is his full build thread, but it is the last couple pages we talk e85 with the GTM kit: http://www.the370z.com/members-370z-...k-out-lot.html
He is currently working on a couple issues to finish it up, but looking positive. The only negative I see to e85 for us, is we are static with our boost. So we run xPSI and throwing on e85 might give better cooling and allow a little more timing but to see full benefits we might have to bump up the PSI or generate better flow in/out of the engine to great that perfect efficiency setup.

thanks mate! will keep an eye on it and see how it goes.

yeah I was thinking the same along the lines of the static boost thing.. guess we will wait for his results, we might have a lot of E85'ers coming up haha

Yep, the TT guys are eating it up right now but the SC owners are staying away. I want to make the jump (tons of e85 stations here), but not sure if it is worth the investment. I don't really need more power, need at 400 since 2010 and love the level, but the added protection is very nice.

yeah I'm hearing you there, extra protection would be awesome.

have you done any tests on your local stations to see how the levels vary? that's the only real concern I have about swapping over, is getting a low batch of fuel, guess would need to at least have a test kit every tank of fuel.. kind of annoying for a daily drive, if the other guys results are good though, it'll be worth it to me even to check every tank.

I've got 3 stations within 5-10 mins of me, might run some tests over the coming months and see how the levels vary.

Not yet, I know the top stations people use here and I am near or travel daily past them.
Probably before I made the jump I would test a few to compare differences mostly, and my other goal is to have a second car by the time I make the jump so I am not that worried about DD it anymore.

yup yup, mines not so much a DD but it is my only car, I work from home and only head on-site for hardware replacements/meetings etc (IT consultant).

so it won't be so bad, I can generally go a couple weeks at the moment with a tank of fuel if I don't go out to any car meets on the weekend.

well fingers crossed for decent results! we know there will be 2 more at least if there is decent results ;) haha

You'd have to look at timing tables to see all that. Nissan is really confusing as the timing tables aren't in degree but some kind of unit based off cylinder pressure.

It doesn't look like it is running super rich, but it could be smoothed out a little and optomized. Right around 12-12.5:1 AFR is going to be your target range (closer to 12:1 to be safe).

As far as a summer tune...the tune should be able to compensate for the temperature differences but I would have it checked when it gets warmer to make sure everything is good to go.

sorry about that I took it personally.

so whats everyone running in terms of redline now with the kit, are you guys keeping standard redline or increasing further?

Unless you have upgraded the oil-pump, don't exceed 7500rpm.

fair enough, have any idea what oil pump people are upgrading too?

Nismo oil pump @ US$1250

I ran had my limit at 7800 , but never hit it shifted at 7500 to so I think I may have bounced like 3 -4 times at the track tho, I shift manual ALL the time and took some getting used to how fast the RPMs ramped up

Hey Mikey !!!

Check your Dyno Graph ... and look for where the Torque Curve starts to dip ... That's your shift point.
You still may show HP increasing but you will be losing the rate of acceleration.

Do some testing, and you can fine tune the shift point to your liking as needed.

If you did the pull thru the gears you may notice a different shift point for different gears...good to know if you plan to race.

I ended up installing an Auto Meter Shift Light (guage style) using an 'A Pillar Guage Pod' crafted by 'Gale Force' - one of the members here.
This shift light allows you to program each shift, and being located in the guage pod, it is much easier to see than the OEM one ...

My dyno graph indicated to shift between 6900 and 7000 (with some other performance upgrades) and that worked for me.

Sweet, good to know about being able to program the shift light per shift. might look into one as well :D

still debating whether to go the e85 route.. waiting for some results from another member doing the same, as like everyone else we really don't know how much gain there will be as we can't just up the boost like a turbo setup, we could however increase timing/tune afr more aggressively.

Every Stillen supercharger that seem to have had trouble seem to be when people try to get more power out of it, be careful!

haha will do man!

won't be doing anything for a while, it's pretty good as it is already :)

I have seen some issues when people try to pass 450 whp. I've seen a few doing 430-445 whp without too much issue. Past that we are still testing right now. We are developing a high boost kit and are seeing what needs to change to make it safe and reliable power upgrade.

If you get that worked out call me for my credit card number!

Will do Jason :)

Me too :tup:

Me threes!

Not really anything with the kit "if" you only looking for 450WHP. I personally don't like the heat exchanger bolted to the radiator. You guys should really look at what I did and the hand full of guys here and followed me and used a front mount heat exchanger, there is plenty of room. The other issue is our MAF's( Voltage will max out) Myself and Cliff ran into this issue but again that's if your looking 470ish . I had your Impeller upgrade and UPREV MAF's an was pushing 457WHP and the kit held up fine!! How ever on the other side of that was the sh&t install I had of the fuel pump.

I also had injectors and DW300 pump. I had the pump only cause the dealer killed the wally, and injectors were just incase I reached 500WHP, Which you wont see unless you have a built block.. Boost will be to high to get there on the the stocker, My 457WHP was at 11-12 PSI. You need like 16 to get to 500WHP.

To make 450WHP on your kit you would probably need nothing other than the front mount heat exchanger. :) ..

yes please ;)

it would also be amazing if you guys tested E85 with the current kit + upgraded kit you are developing. I'm sure if there were good results, heaps of people would jump onto this. There is another guy with the GTM SC that is doing an E85 upgrade at the moment, waiting to see his results and if they are good I'll be going this route as well.

Hey bud did you have the 9lb pulley and the upgraded impeller? Im thinking of doing the impeller next.

Hey , I did not . I would have seen too much boost on a stock block. With the 9lbs pully I would been 13-14 PSI . At the time my tuner told me that would be too much on the st ok bottom end. I do know I snapped a rod at 11-12 PSI but there other issues. What PSI AND WHP you at now? I really wouldn't go 12+. But that's just me. Even if I don't go back to Stillen ( really want to) but tossing some ideas about FI twins and AAM twins. If went that route is be at 6-7PSI at the most. If I go Stillen I'm not changin the boost just the heat exchanger again. I can live with 400+ WHP I think ;/

I did exactly this ... wanted to make 500whp.

Upgraded the Vortech Impeller to SI trim and used the Stillen 9 lb pulley ...
It produced 483 whp/ 378 tqe at 11.9 psi.

Grenaded the stock motor as a result, and now I am having to rebuild it.
(Should have built the motor in the first place, it would have saved me time, money, and grief).

Can't say for sure if your stock motor will hold up, but I definitely wouldn't do both the impeller and pulley at the same time...

Do you guys think that the test pipes could cause a little loss of hp? I had cats on it and it seems like it's a little sluggish at times. I'm thinking about going back to cats. Plus the fire balls were pretty cool.
