Dynoed the Showcar finally on the T04R

[nissanfanatic]

Well I finally got to dyno the new setup today. I ran it on the Enthalpy tune due to time restrictions in getting the AEM tuned. Even so, today went really well.

Details:T04RFull race manifoldstock internals(Cometic HG with reused stock head bolts)BC 264 camsEnthalpy tune110 MON fuel24psi, then 25psi

So, my first run, I had really bad richness issues for obvious reasons. It did 449whp at 24psi and I saw "rich" a couple times on my wideband. So I pulled fuel and ran it again. This time, it did 480whp at 24psi. So, I decided to throw in another pound of boost, and it did a final number of 496whp at 25psi, which turned out to be 507whp with STD correction. Here is the graph:



So it was definitely a good day at the dyno

HOLY ****!

ON STOCK INTERNALS?!?!?!

how long you been running that ****?

[ghx407]

well, this is just sick...

[kpc_0721]

Wow man those are some awsome numbers, what are the specs on your turbo that you are running though? Im pretty much gonna be running the same setup just on 93 octane and a megan manifold but my motor is bored .20 over with arias forged 8.8:1 pistons so this gives me a little hope with my setup If I even made 400whp around the same amount of boost I might just bust a nut haha.

[nelson8708]

its all in the tune....cory has been in the 400+ area for a while now. I believe the motor blew not to long ago (ring lands) and he just got done rebuilding it with stock pistons.

[nissanfanatic]

Acutally, it blew twice. Both times, it was due to the stock CAS wheel not agreeing with the AEM. First time, I rebuilt it and had it done for the track. That night, it blew again at the track, and I started on rebuilding it that Thursday night and had the engine on the stand ready to go into the car on Friday morning. Both times, I simply swapped in used piston/rod combos with my rings. Seems to be doing alright, so I'm happy. But yea, it has been running since early September, and quite a bit of it has been decently high boost as of lately. It is always above 350whp, even on pump gas.

[neverlift]

wow man! push it. you push it real good! wtf is up with all that break up on the chart? looks like detonation. never the less great job. that aem ems should work good via nissankat on my local board, he is pushing around 1bar making over 330whp been doing so for some time... gt32 though.

[nissanfanatic]

Well I tried it twice plug and play and it didn't work. I ran safer timing values than my Enthalpy ECU runs and it blew both times. Either way, the Enthalpy tune works good for me for now. I did 353whp at 1bar on my old 50trim setup with the Enthalpy. I woudl guess the current setup might makea little more at 14psi, and I may try to dyno it on street boost just for fun.

[S13FX]

Dude I wanna seem some 1k numbers on that stock block.. NOW GET TO WORK!!! hehe.

But honestly thats pretty impressive keep up the awesome work.

Now where is my PICTURES!!!???

[Florida240sx]

We need ot meet up. If only my damn ka would run correctly... bad distributor perhaps.

[neverlift]

so pnp it didnt work call aem .... street boost lol rpm of spool up? dood I'm talking about says around 4400 or somehting, I'd feel deprived being used to boost anytime...

great number regardless, I was just curious about the "hiccups"

yeah a florida kat meet woot!!!!!!!! a few guys in town run them...

hey florida, sohc dizzy? I may have one at the other place...

[nissanfanatic]

I have the AEM issues isolated, I just need more time to install the AEM and retune everything. I don't get enough time away from work to get the car back on the AEM. I still daily drive it and drive it 100 miles home and 100 miles back every weekend. I despise driving my backup car, so I usually just leave well enough alone.

As my graph shows, I see full boost around 5000rpm. I can't stand instant boost cars, and none of my races happen at 2000rpm anyways.

[neverlift]

my bad saw you making good power down low.....

I like my instant boost, but wouldnt mind a few hundred more rpm of lag for d/d, its give and take. I like having a really fat power band but spinning in 5th getting on the highway is a pita too. btw my races dont always happen at 2k either but its nice knowing I dont have to downshift to have that kick.

[480sx]

Im wondering about those HP spikes you see while your in boost, any idea what that is? Maybe just a dyno specific issue?

Still 25 pds of boost on the stock pistons is nuts. Makes me feel good about my Enthalpy tune.

[Jookmasta]

first off congrats on the great numbers. u must pull like a freight train from 4 grand onwards and by the time u reach redline, ur taking off? lol. my question is did you get the enthalpy ecu reflashed for this setup or are u still running the old tune for the previous setup? also, are u still rolling around on those toyo's? lol. good stuff man.

[turbo2nr]

nice numbers cory!

just curious why you didnt go with the 272 probably b/c of having to upgrade the valve springs and stuff? just wondering because i wanted to go 272's..

either way big turbo rocks! i wonder how my 62-1 would feel on 25psi.. damm

[salt!]

congrats

[Craving4Boost]

first off, great job as usual Cory. you got one bad street machine. So putting all "glitches" aside, how is tuning with the AEM EMS in general? this is considering you've taken no classes and stuff. how goes the self-taught process of aem ems?

[nissanfanatic]

The AEM in itself is easy to use. I had my car running really good on the AEM until I had the issue with my stock CAS wheel. That was really the only thing I ever inquired about to anybody. I never really had any issues tuning or anything.

I am on 17x9 Kuhmo MXs now.

The HP spikes are probably partially due to the timing and it may still be a little rich. I am still on the same original tune I got from Scott. Most graphs look like that anyways, its just that people post corrected and smoothed graphs. I post what I put down and nothing else, uncorrected, 0 smoothing.

[placham]

your running garrett T04R right. Do you have any pictures of engine bay with turbo on? just wanted to get an idea of what it looks like in car. I want to get T04s I think their the same, sizewise just was not sure if it would fit and what manifold to run. your running full-race, what about downpipe, and wg; pipe just wanted to get an idea. how is the spool with that turbo and manifold?

By the way does AMS still offer manifold and downpipe, I checked their website about a week ago and did not see them for 240sx. Unless I missed it. Because I remember that they had some sort of discount on their manifolds for 240sx, unless they sold all the ones they had and now only do special orders.

Thanks

[kpc_0721]

Yea man pics of the car and engine bay would be kinda tight and placham I might be heading down to their shop tomorrow and if so I'll be sure to ask cuz I was wondering the same thing, ill be bummed if they stopped making kits for the ka

[nissanfanatic]

The T04R uses a T04S compressor housing.

Do a search for my most recent install thread. Just search for all threads made by me, I don't make too many threads.

[placham]

Dame that thing is huge!!!!!!!!!!!!!!!! You made the down pipe your self right. Its a v-band from what I see. The T04s that I want to buy has a 4-bolt housing exhaust housing A/r is .82 or.81(think), would like to go with smaller a/r for exhaust looking for no more than 400hp.

I see you moved the p/s reservoir, is that the only thing you moved. Where does your wg pipe go?

kpc_0721 , Yeah I was looking on their web, just to check out prices but could not find any turbo exhaust parts. And I know they made them, and about half a year ago or so they had some sort of price drop or discount. But now they might just do special order at regular price.

[red boy]

You have one hell of a tune. Alot of people with fully built engines that work @ shops only hit 400-450hp. And countless time on the dyno. How did you get so much hp with 25 psi. Ive seen alot of 400hp @ 18-21psi. How did you jump 100hp on 5 more psi. whats your secret? Does 110 race fuel help that much? WhaT shop tunes your car, Id like them to tune mine when it's ready.

[Jookmasta]

he's running an enthalpy tune and the real main reason for his power output (besides the tune) is that he is in the turbo's sweet spot............if you research the compressor map for his turbo and plot out where he falls in the efficiency (more specifically, which circle of efficiency he falls in). the race fuel just helps to reduce knock.

i will say that at that power level, i would think (at least i know myself) would have a hard time getting bored of that power level. 500rwhp in a 2700 pound car is insanely fast............

Here's all the pics yoposted in the other thread Cory. Great friggin numbers man. Although I figured you'd have a "flash" spool effect showing on the dyno sheet. When I was running the T04E on the RB20 it went verticle once the damn thing spooled up. What are the boostnumbers like at WOT but under 5k? I was seeing about 7 psi over 3800 or so, but nothing over 10 till 4900 give or take a few.

how's the quality of the full race manifold compared to your old one? ground zero was it?

[SSDwellah]

FYI: I know with RB's AEM had this problem... you have to switch to use RISING EDGE on the CAS sensors, not falling edge. A lot of people who report problems of the engine running fine for a while and then just stopping due to a misfire or losing sync with the CAS changed to rising edge and it resolved their problems. Good work on the KA24DET though... I had one before but only 10PSI not 24 . It's deceivingly quick.

[nissanfanatic]

I had it on rising edge. I followed all the information posted on the AEM forum. The issue is the stock CAS wheel. Its not compatible with the AEM box in some applications. Its hit or miss.

[red boy]

I was going to use aem. So will it work fine on my engine or not?
