dyno tuned..(FINALLY)

[smxtmpr34]

That manifold is awesome.. but is all the modification Nessary? I was looking at the same ebay one but was worried about clearance and what not... im really new to this motor.

[KoshiLe]

Is there a reason why you still run a MAF? I was wondering because i thought Apexi Power FC runs off MAP.

[s14 2510's]

djetro power fc use mapregular pfc uses mafYou have a long road a head of you...

[240z4u]

Nice job!

Great numbers, glad you had such great luck with the modified manifold. What other mods did you make? Mind sharing in a different thread? I don't want to clutter this one.

Sorry but im also raising the

Dyno graph or

prove me wrong, I do want to see this

[meet07]

where did you get the wastegate piping??? I know its like 321 or 304?? But where can it be found??

[matafied]

i think it was all custom (meet07)

[MonekyWorks]

cool, any more engine bay pics?

[shally2186]

hey...i will brag for you to all of my honda buddys over here in PITTSBURGH PA...lol, and they think that their cars have ballz...great job with the car!!!

[meet07]

Yeah I understand but I wanted to knw where the piping can be found?? The sch 321 or 304......what ever it is??

[Cjmartz2k]

chris will kick your a$$.

jk.

Thanks for the vote of confidence

Unless I can get the Skyline back to the states, it's probably going to have to stay internet bench racning though. I am pushing about 500rwhp though

[240z4u]

Maybe I missed it, are these dynojet numbers or otherwise? What was peak torque and where was it?

Evan

[S14-NEO]

these numbers arent from a dynojet but rather from a mustang dyno and rumor has it the mustang dyno read lower than what they actually are.. as it turns out i have to go in for a retune. before i got it tuned, i decided to up the output on my alternator. so i went with a quest alternator and ran into problems getting it to work properly. i had to get the adjusting bracket modifed alot in order to get it to work properly. problem was i didnt have enough time to do that before i got it tuned so i had to jury rig it. as it turns out it didnt work very well. and once i got the thing properly setup right , everything within the car is now getting the correct amount of voltage and yes that includes my splitfire coilpacks. so now my car is running lean. im not mad about it at all..kinda glad that just means my car wasnt 100% on the dyno .

[Shocker]

Was the dyno chart on the first page? I don't believe I've seen one yet....

[240z4u]

Thats a great number on a mustang dyno, congratulations once again.

Glad to hear you got your electrical sorted. I was one of (if not the first) people to do the quest setup and its not exactly straight forward! Worth it in the end.

I think he said he is waiting for a retune for a graph.

So what was peak TQ? COME ON... inquiring minds wanna know.

Evan

[S14-NEO]

yeah im getting it retuned this saturday at japtrix and yes i was waiting on that before i posted up a dyno graph..as far as peak tq she managed 330ft lbs at the tire

[240z4u]

Thanks, reason I asked is because I attempted to tune my car myself last saturday. I did okay, but the tq vs. hp does not look right. I need to reevaluate some things.

Thanks dude - Evan

[sil_eightyRPS13]

well i put down 523 at 1.0 bar..nahnah.. but i have to wait a lil longer..lol =( nice response 3200 is that full boost??? anyone have a graph with at .82 GT35R??? im curious to where it hits full boost 4200????

Heres my kaboom graph, 35r t4 hot side .68 a/r



there was no adjustment of timing at all during this pull, It was only at 18 degrees it never was advanced then retarded since it was the first pull.

BTW 14 psi as well, once again just getting baseline maps setup.

[240z4u]

Shocker, thanks for the graph. Gives me a better idea of what one should look like. I am still learning the tuning end.

I have come to conclude that dynos are not useful for anything but tuning (which is what they should be good for) and bench racing. Just not enough consistency.

That said, the mustang and dyno dynamics dyno typically read 13% lower then the dynojet counterpart. But thats all in the setup and operator. I am done being concerned about the numbers, but more concerned with making as much power as I can.

Trap speed tells the whole story, unless your a terrible driver like me.

Exactly TRAP speed tells all, I think of dynos just as a tool to properly tune the car, the track is the true performance number.

BTW boost will come on faster as its raised, and timing is actually taken into consideration. I should have another graph (a good one) within the next month.... I'm expecting an end result of full boost around 4200 with this setup, we shall see how to new cams help...

[240z4u]

Rock on man, good luck with the next dyno session.

heres mine... http://members.shaw.ca/sil_eighty/dynosheet.jpgim looking to switch to the 35R .82 and can get her spool a 1000RPM sooner and still have a 600HP potenial....my TD06-25G-16cm hits hard at 5000 dont even need a clutch kick for third gear drifts...lol anyone know if the .82a/r is efficient to those numbers...??? and im looking for T3 four bolt external layout numbers if anyone has some... sorry for the thread hi-jack... but i want my car to be a little more driftable, its more liek a wangan runner right now...

If you want that get the .63.... it will be very driftable and come on very hard lol

your running the inline 044 with an intank pump through the same line right? no issues?

im running a bosch inline under the hood and a nismo intake on aftermarket 1/4" line...well thats the way the japs had it rigged up... im thinking of doing a nice surge tank setup to make it nice and a lil more fire retardent friendly(2 bosch's perhaps)...lol... what is the maximum power out put with the .63 GT35R 450-500?? .82 480-550??? i want at least 500 out of her, and not hot air either...im sure the .82 would spool fully by 4200 with my setup...and compression

Depends on how much boost, but a guy over here is making a guestimated 550hp at the motor on a Evo I with a .82 GT35R at like 1.8 bar. Pretty good guestimate though.

I really hate dyno numbers, they all vary. I like trap speeds.

I've seen charts of people making 620-630 on a 35r .82 on c16, I've seen them only make mid to high 5's too.

I don't doubt you couldn't get an easy 500 with a .63 hotside, gonna need gas of course, even more since your high compression. But that is more than PLENTY for drift. 4th gear sweepers much? lol

well im getting lots of fuel... 555cc injects are almost maxed out at full boost(98.8%...) to my understanding injectors run better near max. better fuel economy i was told, and more efficient duty cycle. but im sure switching to 740cc wouldn't hurt. fuel pressure is at 60psi,(ha, any higher and we keep blowing o-rings. so we doubled up on imperial ones...nice lil trick) compression is 9.8:1 (roughly), head quench has been removed, running HKS 272 8.5 lift cams,weisco 87.25mm pistons,eagle rods..etc runnnig VPc14 or sunoco equvillant (114octane)if i go .82 will i see full boost at 4000-4200? and peak numbers in 550whp range? i am only running 18psi to get 581whp right now(but hitting hard over 5000rpm is gay unless your on a big track... tq is a lil low in my opinion 423tq... i think a smaller hot would bring the numbers up a lil bit...and yes Fourht gear sweepers are no problem here

[Cjmartz2k]

Whoever told you your injectors would run better at 98.5% duty cycle at 4 bar of fuel pressure is an idiot, and you can tell him I said so.

[neonbomb]

I thought i read somewhere that running injectors over 80-90% duty was bad?

i guess not?
