If thats so, is it safe to say that the kit is still safe enough to be pumped at 9 or even 10 psi? If the A/F was identically rich(safe) as it was at 8 psi.

Stock internals of course.

 

As most know we installed two Turbonetics kits in G35's last week,one 03 the other an 04. Both had Tanabe SM-Hyper exhaust and SSV intake installed as well as Turbonetics reflash.The 04 also had ud pullies and headers which the 03 didn't and both were within 4-5 hp/tq of each other which was about 350whp @ 7lbs. Both cars are running a/f about 11.0 think,I'll ask our tuner to add info tomorrow.

All factory like motors will not create the same power and fine tuning is critical to maximize the power as power adders are added. Example,our shop 04 Z made 362whp/371tq stock less cats @7lbs and a/f 10.8.
We are doing a APS TT kit in an 05 G35 later this week with standard programer provided with the kit. We will be installing an intake(hopefully an APS tall boy)if I can find one in the USA,and Stillen dual exhaust. I'll dyno and post results next week.

Question is what is the highest boost I can run on my stock motor? We don't know but are testing with the shop Z,the weak link are the rods as all know. We have played with 14lbs on the dyno and pulled over 450whp/470tq. I have been driving the car almost daily for a month at 12lbs with no issues,a/f at 10.8 WOT........We will see,still learning!

sweet man... let us know how the 05 install goes.. you will probably get done before me but im putting a aps tt on a 05g35 coupe 6mt with test pipes and the hks true dual.. also with pulleys and clutch and flywheel.. im shooting for 450rwhp.

 

Speed Dreams,

Thats on 93 octane right?

 

91, ya were crazy ****ers.

 

Noooice!
Interesting on how the stockie would hold...please keep us updated.

I dont think I'll have the ***** to do 12psi at stock internals...maybe 10 the most...

 

I am running my car daily at 11 PSI and not having any issues. My car is still on the rich side, so the upgraded pump/injectors can DEFINITELY flow enough fuel at this boost.

EDIT: This is using 93 Octane gas.

 

Upgrade pump/injectors that came with the kit? or larger?

Im going to be on 440ccs.

 

He's on the ones that came with the kit.

 

It's mostly in fuel mgnt and tune as long as you don't go beyond the laws of physics of the oem motor..........

 

Yep, sorry if that was confusing. By "upgrade", I meant the ones that came with the kit (as in upgrade from OEM).

 

Right now I am measured when I dyno'd at 8.5psi (added three shims in the wastegate), but when driving my boost gauge shows slighty under 10psi so I might def. be up for adding some more shims since you and I are running more rich than 11.5

I even sent my ECU to Technosquare in hopes to get more into the 11 area, and I got them to raise the rev limit to 7100 rpm though what is the point in that when you lose power over 5K cause I am so rich (10.5).

Well today get off of work, Technosquare sent me the ECU back... Put it back in and I went from idle'ing at a little below 1000 rpm to now much lower than that and it is funky... And now I can rev past 6600rpm, but I am still more rich than 11.0

I am going to see if I can send it back so they can try again, it sucks I have to do this until I can make it to get this Emanage Ultimate installed and tune'd which might not be for another couple of months.

 

We put a 7 PSI spring in my Wastegate, which dropped me down to around 8 - 8.5 PSI, and that put my power at around 335 WHP. That's how rich I'm running.

Even with the 9 PSI spring, my A/F is in the 9's (low low 9's in fact) above 4500 RPM. We were never able to pinpoint exactly why my car is so rich, but an Emanage is definitely in my future as well. I'm so tempted to put the Emanage blue I have sitting here in the car (I have the autosport PnP harness, so no hacking) and do the injector scaling thing to raise my ratio. Funny thing is that I'm getting great power right now (370hp/370tq), so I'll probably be closer to 390 once I'm in the 11's during peak power. I may even have to put the 7 PSI spring and a boost controller in so that I can tone it down a little once the fuel curve is proper.

 

Hmmm... I am right now at 322 WHP and 325 TRQ at my current psi, damn that you dipp into the 9's geez...

Well hopefully it will work out for the both of us... soon

 

Wow...you're not getting near enough power out of this thing. You should be getting at a minimum 30 more WHP than you're getting. It sounds like something is wrong with your kit/install/car to me. I would imagine even the folks at Turbonetics would say so. What dyno were these numbers generated on, dynojet? That just seems way too low.

 

+1

I'm only at 7.5 psi and putting down 358 whp 358 wtq. But last nite I did couple runs on the highway and looked at the boost gauge, I saw it just a little below the 10 psi mark. This is with the stockies headers. The 7.5 psi was with the Stillen headers. I'm waiting for the dyno shop coming back from vacation so I can dyno and see what's going on.

 

Iam pretty sure Turbonetics suggest not to use aftermarket headers with their kit? Or am i just mistaken?

 

YUP! But just to see if it helps or not . Taurran and I did the experiment and you guys can benefit from us LOL.

 

Hmmmm... It is possible but the car runs fine until full boost so IDK. Numbers generated from Dyno Pack... I have been told numbers could be lower than most other forms of dyno readings but once again IDK.

It is just booty to me

If I could get the time off of work, and a garage so I don't have to attempt things in a day span I would go back over the fuel pump/injectors/and spark plugs.

Gotto get some time so I can check that stuff.

 

i'm guessing you didn't get a baseline on the same dyno before installing the turbo?
