added new numbers!


So here it is. I only did an hour on the dyno and I didn't get to max boost because i had a charge pipe blow off. My fault because i didn't have it tight enough but it required me to leave the dyno to get under the car to fix so i called it a night.

628hp
561tq
22psi
SAE correction
smoothing changed to 5 for printouts

I will have all the runs emailed to me tomorrow.

Intake temps started at ~80* in the beginning of the run and the highest i saw was 120*. I started at 18psi and did a couple pulls then adjusted fuel and pushed more boost. I upped the timing a little at 18psi and 20psi to help out the e85. I didn't advance them much though. When i got to 22psi I was pulling some fuel and playing with my boost controller. I was still low 11's and sometimes dipping down below 10.8 so i have more fuel to pull out. At 22psi i did a few pulls to get the fuel correct then i advanced the timing 1* before deciding to just move on up to higher boost. I was about 10* timing at peak tq and then up to only 13* timing at 22psi. Plenty of timing left.

Well the next pull at 26psi a charge pipe blew off because i didn't have it tightened down well from the dyno 2 weeks ago when i had to remove it to change out my boost controller lines. I had to take the car off the dyno so at this point I called it a day. I'll be heading back soon though. I'm planning on taking it all the way to 30psi since that's what i can see on my map sensor. I also will advance the timing to optimize e85 use.

This dyno looks really bad up top and i'm not sure why. After looking through all my runs they were normal then started getting worse like this towards the end of all my pulls. I'm going to take a guess and say the abuse on my os giken twin disk has brought it to the end of it's life. It was pretty thin back in august when i had the engine out but i decided to keep using it. That's the only thing that can explain that weird presentation. If anyone else has thoughts please let me know. That's what the shop owner thought could have been the issue also.

Sorry i don't have boost or a/f reference. I'll screen shot my logs of these runs (i labeled them) and you can see what rpm and boost i was at on each pull. I'll also show my timing logs so if anyone wants to review it.

after review the clutch is in fact slipping. New clutch going on so i can see actually what this will end up being. The curve should push up close to 700hp on 22psi. I'll be taking it to 30psi once the clutch is in it.

edit:

So jon at ET Tuning sent me the drp files and i was looking through them. Since i didn't trust the tach signal (it was having issues) i decided to log them based on wheel speed since that can't be messed with and alter my graphs. When i was doing that i found 2 more runs that apparently he never saw with more power. I put it in STD correction with 0 smoothing (because that's what i see on here the most of to compare).

So the new power is 652. I'm having him email me the tq runs so i can put those together as well.

Also, the blue line i have highlighted is my second pull. My first pull never has the cams working so i did a back to back pull. This is at 18psi with my timing set the same as I had it with my pumpgas map. I had not yet messed with 18psi timing levels.

So that's 607hp on 18psi and it appears my clutch wasn't slipping bad but it could have still been slipping slightly.

edit: for anyone wanting to know rpm or whatever this is a 6mt, 4th gear pull with 26.5" rear tires on the 3.5 final drive.

 

great numbers Jeff! i've been following your posts on my350z so i know you've had to go through a lot to get to this point. looking forward to seeing what you'll get when you get the clutch sorted out!

 

Thanks

 

nice.. congrads

 

is this kit available for a g35 5at, or only 350zs'?

 

no 5at option because he hasn't had a donar car to use in order to get the correct fitment around the larger transmission.

It is available for g35 and 350z in manual transmission.

 

When i went above 21 PSI the seals on my Cossworth CF caps were leaking..lol and also the charge pipe pop off also =).

 

Lance they have billet caps now. Also might need some boost stays... Are the pipes all bead rolled?

 

mine wasn't tightened down enough. I just had that pipe off earlier in the day to change some stuff.

yes, BP kits are all bead rolled.

 

Correct, bead rolled and stainless T-bolt clamps from turbo to TB, no worm gear clamps.

If you guys have any specific questions just PM me.

 

Hey Dan

Yea but i don't want to lose the CF looks..lol Dont they have to be wielded to the CW thou. I think they are beaded not sure how greddy makes thier piping..

 

Very impressive!
Is this all with stock bumper?

And Sasha, I might be heading to Calgary in the summer so I'll let you know as time nears.

 

yes, here is a pic of how the car sits 24/7

also, for tuning it was removed because i see way higher intake temps on the dyno than on the street due to severe lack of airflow on the dyno. I see about 50* less intake temps on the street. I made sure to keep intake temps the same as what i see from all my logs on the street so my tune is the most consistent.

 

For sure, just let me know about a month ahead of time. I can have everything ready for install. It will take me one day to get it all on the car and ready to go.
