Finally got my car tune today or semi tune since my power fc ended up bad so i've sent it to repair so i got me an AFC for now untill i get the PFC
mods
sr blacktop
HKS 272 step 1
Greddy Rocker Arm Stoppers
T28 (s15)
Greddy elbow
greddy TI c exhaust
FMIC XS power
HDI boost controller
nismo 740cc
nismo FPR
Z32 MAF
APEX AFC
HKS Super Sequential Blowoff Valves SSQV

made 296.74 torque and 289.44 HP. that low numbers was the first pass at 6-7 pounds the other one we tried 20 pounds but boost falled down to 16 pounds right at peak , we tried putting a T and got a bit better but still falling to 16 it wasnt holding 20 , i think if it can hold 20 pounds it would go up till 320 or so
once i get the PFC back from repair we will try again . dont like the AFC , it is momentary

Looks like a nice setup!

How much boost can you safely run on a stock bottom end SR?

well, on race gas as long as the AFR is clean and the head gasket holds up, its really more a matter of how much power the internals can handle, on pump i would think 20 would be pushing it, esp since its blowing hot air at that point.

ill keep that in mind . thanks for the input
very sick how that thing pulls u when boost kick in .

ROIDMONKEY · 10-30-2007, 08:29 PM

Cant answear that question since is my first SR . im boosting 16-18 right now

harangatang · 10-30-2007, 08:35 PM

289 whp and 296 tq?? To me, that sounds pretty good for a stock sr minus cams and a t28. And you shouldnt be boosting that t28 to 20psi. It wont like it at all.I believe the efficiency rating is around 15psi if I'm not mistaken.

steve shadows · 10-30-2007, 08:38 PM

hook up a catch can to that valve cover T before you drip oil on the exhaust manifold and blow the welds on the passenger floorboard

forgot that . good eyes dude

Gjohnson7 · 10-30-2007, 08:40 PM

Alright, that's basicly what I was getting at. 20psi on a almost stock SR seemed like a lot to be pushing.

johngriff · 10-30-2007, 08:57 PM

Your run is bullshit

Humidity today in 33196 was more like 80%, not 40%

Your dyno operator fucked up.

where the humidity is.

ehh i read it wrong, i think.

I dont know its high.

I thought it was 296ftlbs @ 7psi. I was going to lose it. 16, sounds closer, but still way high...

ROIDMONKEY · 10-30-2007, 09:19 PM

U got it yes , fynetune really nice dyno setup. it was falling down to 16 but boost controller was set to 20

johngriff · 10-30-2007, 09:24 PM

DynoJet is not a nice dyno setup.

Maha (http://www.maha.de) is a nice dyno setup.

DynoJet is NOT a load bearing dyno, that is why your boost controller was dying.

Z U L8R · 10-30-2007, 09:41 PM

not too shabby for afc, you'll make more power/torque through out the powerband once you get your pfc back. i wouldn't recommend you push it passed 16psi either though, and yeah ~300rwhp pulls pretty damn good. good job man. my only advice is (and i'm a total hipocrit) u gotta know when enough is enough. like turning it up 4 more pounds of boost, which is mostly just hot air, to only gain ~20hp isn't worth risking the motor in my opinion. just upgrade the turbo. i don't see ur motor lasting that long @ 20psi on this t28, i think you'd do fine keeping it at 16psi till you got a bigger turbo. just my .02 . i'd rather see you kicking peoples asses with 300rwhp than spending money on internals for your sr and driving around the beater. if i were in your shoes i'd keep it at 16psi, when the pfc comes back in, get another tune @ 16psi. and drive on the new and improved 16psi while saving up for the bigger turbo + exhaust manifold. all in all i think you did a good job, nice numbers

defenetly keep that in mind , thanks bro
johngriff how did u get those positive reps ? JK bro

GabeS14 · 10-31-2007, 01:42 AM

Nice torque numbers!!!

johngriff · 10-30-2007, 09:48 PM

Doesn't matter, tune ignition timing around fuel and boost, run as much as the octane rating is going to handle, 4 more psi isnt going to break the cylinder head off the engine.

4 PSI Can be the difference between life and Death, My buddy cracked his cylinder wall just going from 12 to 14lbs of boost. So it can happen,

Good numbers man!!! Keep up the good work. I like seeing good numbers, Dont let these guys intimidate ya on here, There prob just pissed because they cant get those numbers out of there motor, Everyone's setup is different and not everyone can handle it.

So congrats!!!!

That is a statement made on 0 quantifiable evidence. The reason a cylinder wall will crack is because of detonation. Detonation is caused by boost exceeding the octane rating, or improperly tuned ignition timing, or bad af/r. It is not going to happen because of increased pressure.

Even in the cheapest motors (kia, daewoo) you will bend and break rods/crank/wristpins on properly tuned cars with too much boost before you crack cylinder walls.

Your friends car sounds like it was open deck, I am thinking it WASN'T a nissan.

I was waiting for that man, cracked cyl wall, WTF? Not normal on closed deck at all and not on a good tune. I saw it recently on a new Solstice, open deck, that was pushing 15psi off a 20g without a proper tune.

Jump on a dynodynamics.

It'll be a cold dose of reality.

yeah he would be around 240 on hp and 215 trq on dyno dynamics at 16-20 psi.

bro if 240 hp feels like my car is pulling right now . very impressive for 240hp and 215 torque

steve shadows · 10-31-2007, 04:09 PM

yeah just find a mustang dyno or DD, DD reads the lowest

Quote:

SR20DET Stock Bottom End
PE Metal Head Gasket
HKS 264 Step 2 Cams
Peak Performance Valve Springs
Peak Boost Manifold DP Kit
38 MM Tial WG
STOCK Intake Manifold

PWR Racing FMIC
Haltech E8 Plug and Play EMS with Boost control
Clutch Net Pressure Plate
Stock Sr20det Flywheel

Custom Turbo I made for Luke- So he can drift and Drag race.

360 Degree Journal Bearing CHRA
Garrett 50 Trim Compressor Wheel T04E
.63 Turbine Housing T3 Garett standard 4 bolt
Turbine wheel (secret) hehe

12 psi 91 octane Safe Street Tune - By me Steve

I just wanted to compare these in my argument in favor of larger journal bearing turbos over smaller t28 at less boost

just compare straight accross and keep in mind the dyno dynamics reands 15% LOWER than DJ.

this a customers car I tuned at 12 psi on 91 oct.

just fyi.

You still have more power to be made with a little more timimng map and steady state tuning of the cells.

ps you cannot do this on a dynojet

only DD. fyi
