I was thinking the same thing Khoi!

I agree that quarter mile times give me a better idea of how the car will perform on the streets, however knowing overall power of the car is important too. & Its a brag thread

To follow up with what you said FPEnvy, I lost 23% when I baseline dyno'd my car. That 6MT reads at least 10whp higher from what I have seen.

soooooo i'm against 6mt guys i'm at 334? lol :bowrofl: :ugh2:

I can play that game too :tup:
Too many don't document improvements. I know in some locations, dyno's are retarded expensive. In Chicago I saw them for $200+ for 3 pulls. But in Vegas, I can get that for $60 and $40 when specials are going.
Blue: baseline
Red: PPE headers, MD Y pipe & HFC, Tanabe Exhaust
Green: Red + NST pulleys and AEM CAI with no tune.
Busted O2 issue on the green and red dyno plots as well. These are in DIN, SAE numbers were about 6-7whp less on all 3 pulls.

Hahah I have no idea. But, we can always settle this in a straight line. 7AT wins everytime :happydance:

well done with the documentation :tup:

but i know what you mean with the dyno prices. places around here are hit or miss. some places are $150 a hour (3 pulls) and the cheaper places for like $100 are booked up for months at a time.

also i didnt want to do what you did and probably have to pay the shop i dyno'd at to install the parts (or uninstall/reinstall). i enjoyed doing all my own mods and also saving on high labor costs.

i just need to befriend a local shop with a dyno and get free pulls lol

We've tuned cars with similar mods and sometimes the 6MT is higher, and sometimes the 7AT is higher haha, neither trans show a consistent % over the other

:tup: very true sir. i still enjoy being #5 on the 1/4 mile board with only 2 breather mods and a tune on street tires :tup:

i still take the cake on the AAM N/A numbers lol :tiphat:

Correction, Green line and redline with O2 issue, blue is fine.

I got a baseline, then talked to the shop about installing the stuff. They gave me the DRF files and I was able to get them organized on Winpep. Spent over $1k in diag, parts n labor to fix the O2 issue... Totally erased the savings I got from them doing the full exhaust install for $500...

If it were for my lower than normal numbers for the mods I had, I wouldn't have gone FI. It may have been a knee jerk reaction lol. The last straw was when my tuned numbers were 304whp. Dynojets are consistent and I wasn't making much more than a Z with a CAI & CBE.

Guess I'll never be in the 320+ NA club lol.

that sucks man.:shakes head:

honestly with me just having CAI and CBE/TP i was hoping for 320 but would have been ok with 315. then khoi came out like a doctor in the maternity ward and told me my baby made 324 i was one proud daddy........who then jumped around rubbing it in blades faces since he was tuned right before me lol

Im #5 too...stock. First time ever at a track.
I just gotta get modding and then im coming for you :tup:

go for it. my tires were at like 50% when i did that run too soooo i could possibly go a bit faster. then if i go get some drag radials.....:stirthepot:

:bowrofl:

Outside air temp might also be contributing to some of the discrepancies between some of the cars in here.

Attachment 72649
316.79rwhp and 269.6rwtq
This dyno shows my gains with art pipes installed before and after.
Mods.
Fast intentions TDX 18" resonators carbon fiber mufflers
Motordyne ART pipes
Stillen Gen3 CAI
UPREV Tune

Tons more mods but not horsepower related lol.

On this dyno here in my city there is nobody making more than me as a 370z so it definitely has to do with the locations and types of dynos! Also probably hard to compare unless we all got together and had a huge dyno battle lol

I like the 1/4 mile thread too
304 rwhp 7 AT / all moter = 12.34 times
car does not make big rwhp.
Base line was 264. cobb tune in car.

and she went bang. over reved it and it lost oil preasure at 8000 rpm in 4th gear. running with uprev.

Z

no way you ran 12.34 with only 304whp. if so i wanna know what else you had lol

I agree..

Thats like supercharged territory.

not even that but you would need more power, suspension parts, drag radials, and tranny upgrade to do that. i mean i know they got cold air temps in good ole canada but that time is a bit low for 304whp. no offense of course lol

What is this "Z1 intake manifold mod" you speak of? Awesome numbers btw! :tup:

i believe he also has the 4.36 gears and radials on his car which is a MASSIVE upgrade for the 1/4. I outran an 478whp/440tq SS Camaro from a dig with 4.08's. I'd post a video but no street racing vids lol. He was pulling on me HARD at the very end but never actually caught me before the finish. Highway and he would've mutilated me by 4 or 5 car lengths but the power of shorter gears does amazing things. Especially when the 7at with 3.3 gears is faster then the 6mt 3.69 gears from factory, the 4.36 gears would be a destroyer in the 7at. I would roughly assume 20% increase In acceleration.

FP, he forgot to mention the HUGE Gears and wheels haha. He was pulling our johnsons...12.34...

seeeeee no one told me he was running 4.36 gears lol

i wonder how hard it would be to swap in a set of gears for drag days and put the stockers in for when i DD it. never changed a set before.

Ridiculously hard and painful. It takes a pro shop roughly 8 hours to shim and correct everything to make it perfect. Hell, my shop can't even get mine right. 4th time its been back to the shop in 2 months but I'm in Hawaii where good shops are limited. No downtime on my car as I was smart and bought a full donor differential from a totaled 350z. That $100 has saved me 2 months of downtime on my car. I've got my OEM non-VLSD diff and then I've got the one being built with 4.08 gears and Quaife LSD. Takes me about an hour and a half to swap them out now with a lift which would be a good option for you.

soooo go buy a rear diff setup out of a wrecked 307Z and put new gears in there. then just swap diffs for race days. sounds like it's do-able and i have access to many junk yards with higher end cars :yum:

also sidenote: god i miss Hawaii lol that was a good trip to take. stayed with my friend who is in the air force and stationed down there. :tup:

Any 350z, G35, g37, and 370z diff will work. Mines from a 5at 350z. Bolts in with no modifications on my 6mt. Downside is when you drive on them, you're never gonna wanna swap em out lol. Felt amazing. My car just isn't the same without them!! lol

EDIT! MUST READ!!
BUTTTTTT!!! if you don't wanna buy an aftermarket LSD, you must find a differential from the 6mt's to bolt to the 4.08 or 4.36 gears. The housing itself does not matter as long as its from 1 that i listed but you need the actual differential itself to be for a 6mt. IF you do buy an aftermarket LSD, buy it for the 6MT because the ring gears on the AT's are bigger so the new gears would not fit on the auto differential. Everything goes into the housing the same just requires shimming.

dont tell me that lol i'll have to look into a set soon.

I've seen the video, it was sexxxy

And he was spinning both 1st and 2nd, maybe even 3rd

This is the first time I've heard about these 4.36 gears.. Any links or additional info ?

I had a friend who installed the 4.08 gears FPenvy and spun tires into third just from that and a few other bolt ons. That means probably 10whp or so difference... They sold the gears for $450.. thats a good deal for you to consider

That and my drag radial set up I planned out for $1200 ;) 18x12 wheels and some meaty drag radials lol

Its something they do when they do the tune, but its proprietary, so you can only get it done there.


As for 1/4 mile times, that's too boring for me. Sit around all night to get a couple runs that only last a few seconds, no thanks. Almost as boring as standing around all day at auto cross for a few 1 minute runs.

Wasn't this thread for people to post their na numbers, and mods? or did I miss something?

PLEASE KEEP IT ON TOPIC.

I would appreciate that, And so would the rest of the Forum.

Carry on :ugh2:

FPenvy Stop Trolling This Thread!

OK, I'll play. :D After everything so far. 334hp and 279 torque. That's with the G3's, FI LTH's, 12" resonators, the FI CBE, attention to detail (indexed plugs, matched connections, cold throttle bodies, and your standard hot rod stuff), Up-Rev tuning by RT Tuning.

i see low 11's

Z

I would hope that a built motor, built trans, slicks and 600 whp would get you more than low 11s.

:iagree: since a stg 2 TT car is already at 11.1**

We allways start with a conservitive time . i feel that i may have to change the diff as 4.08 may be to much for the car with that engine/
3.7's or 3.56 may work.
1/8 mile is 7.92 @ 90.7 miles.
the motordyne intake with stillen G 3's . make a big difference with the gears, it pulls really hard.
GTM want me to put his GTR manifold on it.

Z

did they even finish that GTR manifold or test it?

Since you're running slicks, you may still be able to get away with the 4.08s. On street tires, no way in hell.
