T67 Dyno

[DrifterProdigy85]

500whp 380tq @ 24psi on 93 Octane

Also did 450whp @ 19psi and 475whp @ 21psi. Power is still being restricted by the stock TB. I'll have the Q45 TB on in a few weeks i hope.

very nice do u have the boost vs afr graph

[mistamacadamian]

nice, that is crazy. when do you hit full boost at? what do you rev to? whats your head set up like?

[DrifterProdigy85]

Head setup isPorted & PolishPolished Combustion ChambersTomei Solid LiftersTomei 270 Solid CamsBrian Crower Springs/Retainers

[DrifterProdigy85]

Turbo hits pretty full from 5krpm.

[jr_ss]

That's an awesome graph... Do you have any of your previous dyno's from the 2871r? I'd like to see them for my personal build...

[DrifterProdigy85]

Thats 2871R .86. Greddy Intake. BC 264 Cams. Megan Manifold. Enthalpy Tune. Was running 19psi and the exhaust manifold was cracked. This was on my stock engine as well. I never got it dynoed with the rebuild and larger cams but did take it to the track and ran a 12.0 @ 122mph. 122mph for my S13 is 400whp.

[500hpSilvia]

lol.. thats funny man.. i just dynoed my car and i got 519.2hp with 378.39tq.. that is really close.. email me so we can see what diff on the setup.. my 25g is maxxed out @ 22psi

[DrifterProdigy85]

Im not sure your setup but if you have a D Jetro standalone, then thats where your ahead. Im still running Z32 MAF on ROM Tuned ECU and 93 octane. The MAF blocks airflow when dealing with large turbos. Also i can squeeze alot more power out of the current setup if i got tuned for race gas and raise the boost higher. 24psi is just the start of the T67 effeciency range. Turbo doesnt hit max effeciency till 32-34psi on the SR20.

[kentuckyslider]

So with 30psi on the d jettro you will be pushing 600whp but no power below 5K? With the solid lifters how high do you spin it?

[DrifterProdigy85]

I rev between 8500-9000rpm. Its not a auto-x or drift car so i dont need any power below 5kpm. Its got plenty of power down low to cruise around on the street. The turbo's been proven to put down over 650whp easily and trap in the mid 140's in the 1/4. My setups still lacking in a few areas to get close to the full power of the turbo.

[JTunedMotorsports]

nice...are you drag racing this car..any times.?

[Kalypso]

I rev between 8500-9000rpm.

woah! your doing mostly drag I suspect.

My setups still lacking in a few areas to get close to the full power of the turbo.

I was going to say, your using the stock bottom end with all this?

[Emperor_Tha]

do u thnk it's possible to do 10.999 inthe 1/4 mile on pump? Do u have launch control? What diff are u running?

[500hpSilvia]

if traction is with him he will get some 10 sec passes out of his car.. its all up to suspension and traction.

[kentuckyslider]

I will be breaking 11.5 in the near future with a 2871 and close to 400whp. 500whp better give me 10's.

[DrifterProdigy85]

Only made one pass so far with this setup. Did 12.3 @ 126mph, 2.0 60ft. Spun badly in 1st, missed 2nd, spun 2nd, spun 3rd, and spun 4th through the traps. Its a nasty car but traction hurts me right now. The track was really slick that night too. Alot of breakdowns and hardly any track prep. Only clean up. Theres no doubt with slicks and launching off the 2 step, 10's would be easy. Alot of my problem with good drag times right now is i cant get the brakes to hold for a good burnout and the coilovers on the car are too stiff. Im gonna be adding a Linelock and switching back to stock rear springs/struts. This should solve alot of traction problems.

Its a fully built bottom end. I lack in the area of airflow right now. The Z32 MAF is blocking air into the turbo causing slower spool and a loss in top end power. The engine really needs a MAP Standalone.

Differential used is a Skyline 4.363 VLSD. Gearing is about stock with the 26" Drag Radials. Still on stock transmission and exedy stage II clutch. Gonna upgrade to Z32 Trans and HKS Twin Plate Clutch once my Trans Am is sold.

i recommend the z32 trans and the exedy twin disk.. you can allways upgrade the twin disk to a tripple disk if you had to. let me know if you want one i can hook you up.. (thats what i have)

[DrifterProdigy85]

Cool. ill let you know when i get the money.

[kentuckyslider]

500hpsilvia, what about your best time. I have a 345whp S13 and I ran a 11.78@117 with stock head and intake.

[500hpSilvia]

havent gone to the track yet.. i do top end. i had to upgrade to a Q45 rear end with axels b/c i kept snapping the stock s13 ones and that now gave me a 3.69 gear ratio. i get 125mph on 3rd gear.. im looking into getting a custom set of gears done to get them up to at least a 3.93 .. i also still have to dial in my cams and upgrade my lil 25g to the new precision sc-6265 once i get that it should put me up to a solid 650-700 at the wheels on pump gas and then i will be going to the track.

[kentuckyslider]

do you have a Z32 transmission? I have already broke 1 SR transmission and I did a KA to SR swap. I run a skyline 4.36 R&P with the 5 bolt axels and 26x8.5 wrinkle walls. I pull consistant 1.6-1.7 60 ft. and sub 12 sec passes. That's with 350whp.

[500hpSilvia]

the KA transmission is weaker than the sr transmission.. i have the VG30DETT trans. great investment..

[DrifterProdigy85]

Im curious to see how many hard lauches the stock VG30DETT trans can take on 10.5 slicks. I thought i read somewhere that Mazworx runs a PPG Dog gearset in theres.

[500hpSilvia]

i will let you know..LOL

[kentuckyslider]

the KA transmission is weaker than the sr transmission.. i have the VG30DETT trans. great investment..

The Sr and KA transmission are the same part number. I have had them both apart when doing my swap and the only difference is the KA has a slightly taller 5th gear. It is a common misconception though.

Another positive to the KA transmission is that the KA 's found in junk yards have never seen over 6500rpm and the bearings are in much better shape compared to the SR's that often see 8000rpm+. Sr transmission's are known for bad input shaft bearings. Mine was loud in neutral. I got my KA transmission out of a S14 with less than 100K miles and it shifts like butter. Here is what second looked like after 1 to many passes with drag tires.....
