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]

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

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
STOCK TB
PWR Racing FMIC
Haltech E8 Plug and Play EMS with Boost control
Clutch Net Pressure Plate
Stock Sr20det Flywheel
Clutch Net Race 6 Puck Disk

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

good numbers thoe

im running right now at 16 . thanks bro
ill try to get the 2871 before i get the PFC back from repair .
average boost for 300-320 on a 2871 is?

[steve shadows]

depends but Id guess 14 psi

I know a pro Japanese drifter the #1 guy on a s15 turbo runs 1.2kg wich is 17.4 psi.. Dont listen to anyone until you see it for yourself.. 18 psi is max for s15. I ran 15psi for a year on my silvia t25 100 octane no probs and drifted and touge the shit out of it!

And a stock bottom end!

there u go . man i cant wait untill the PFC comes to retune again

[Z U L8R]

sure you can hit 25psi with a t25 if you take the vacuum line off the actuator.....turn the boost up ftw

I just noticed u have a 280z , my buddy have a 280 also with a RB26 pretty cool car . love them. hes only making 340 right now . stock turbos at 10 pounds i think . hes putting 2 T28 that he just got , lets see how it goes

BTW i just beat my friend GTO pretty good . he got the LS2 version with "400" hp

[Z U L8R]

=]

Hopefully turbo dave has time today to help me modify my manifold to get his frankenstein turbo on it then tune me up, i'm shooting for 600 but anything over 5 and i'll be pretty happy. my luck i'll get 492 and it won't budge anymore hahaha. i'll let ya know how it goes. i'm on hybridz also , if your friend's on there, what's his screen name?

[White Comet]

to get back on topic, am i the only one that thinks the op's numbers are low? my friend who is a member on here has similar mods on his redtop sr except he has a pfc, no ras, stock cams and stock s13 turbo. at 15 psi he dynoed at 277 hp

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!!!!

hes not here on this forum. hes having problems with tracktion . how do u deal with that on such a light car?

thats awesome bro. wondering when my PFC comes whats gonna be my numbers , cant wait
well i dont know about the dynojet or dynodynamic or any other dyno but i spanked a GTO last night pretty good that comes with 400HP LS2 right? the one with dual exhaust

[DUBCITY]

are u still on stock head gasket?

those numbers are nice for the t28, but you can see it does fall on its face pretty hard higher up.

also, youre running HKS Step 1 272? on both sides?

do they even make step1 272?

yes stock head gasket and yes 272 step 1

when i had 441rwhp/381rwtq@22psi it'd hook with 245/60/14 bfg t/a's which is a pretty soft street tire, i could roll onto second gear and it'd hook the whole way. once they had 40% life left on em they would spin a little though. all in all however i think it's in the tranny. those were 14x7 rikens that had the bfg's and i was running the rb20 tranny at the time. now i'm running a z32 tranny which i'm REAAAALLY liking at the moment. first, second, and third are really close, fourth spreads out a little, and fifth is good to cruise in. i'll spin tires just rolling into 3rd and 4th once it gets to 5-6k rpm, it's still pulling since it's open diff but you can hear em screaching lol. i'm gonna get some mickey thompson et street drag radials...hell they're cheaper than the brand new potenza's i got on the rear right now lol. right now i'm running tsw 16x7.5's with bridgestone potenza pole positions 245/50/16 w-rated. i thought my rear end was a 4.11 open diff, but i think it's a 3.9 open out of an 83 280zx. it's a little short, i'm haulin till 120mph, but then i go in fifth, which with this 3.9? i was trapping 125mph in the 1/4 mile so that last shift into 5th kills it, the stock 3.54 open diff was too long and i was only trapping 122mph with that, it'd hit 145 in 4th gear.....the perfect rear end would be a 3.7 lsd out of an 88 turbo 300zx. can't wait to find one.

sorry to get off topic but you asked about traction.
my advice to him would be to go with some drag radials and if that doesn't help then go with a lower gear ratio.

hmmmm id say about 14-16 psi .. all depends on tunning and what a/r u get .. smaller equaly quicker spool but a tad bit smaller hp ... small a/r will max out at around 360whp .. unless ofcourse u port it / modify it of course .. but avg 2871r .64 will max out at around 360whp with quick ass spool .. or get the big a/r have a better top end and be at 390-420whp ...

who told you they were 272 step 1?

its either a 264 step 1 or a 272 step 2 or 3

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.

OK...mmm... we know...

Let me try this one more time. "Taniguchi", "One of the best street and pro drifters in the world", who has the best sponsors in Japan, who rocks Japans circuits on grip, touge, drift, and on the street still to this day was or still runs a s13 SR20DET with a s15 turbo and boost it at 17.4psi in his hatch. The max is 18psi. No body here in the states knows much. Forums help out but not all the answers. How would a t25 turbo be maxed out at 15psi but the s15 t28 bb be the same first off? Its not! I get all my info for Pro or street drifters in Japan i will run what they run.

nice numbers and i see you finally picked up your Ti-C!

i thought you were getting all your info from superstreet. and since he's the best drifter in the friggin world you'd figure the best sponsors in allllll of japan would do something absolutely crazy and unthinkable like port the housings and put some better wheels in there (at least i'd ask for it).... "how would a t25 be maxed out at 15psi"......does it hold 15psi all the way to 7,000 rpm? i didn't see anyone say a t28 is maxed out at 15psi, i would say t28 should hold 17, sure crank it up to 17.4 psi for the quick .4psi of extra torque really quick (since you're drifting) and if it drops back to 17 at redline who cares, you clutch kicked it and the tires are already spinning. anywho, being best friends with michael jordan doesn't make you an nba coach. the point me and some other people that said no need to go 20psi, was that the minimal gain isn't worth the extra risk. enjoy your car, if you want more power than your turbo's capable of, then upgrade your turbo, why push it till it blows your motor or the turbo takes a shit. that's all =]

[johngriff]

You dont blow the turbo or motor.

You would just be boosting out of the efficiency of the turbo.

Like you know, a compressor map.

[titoray]

and since he's the best drifter in the friggin world you'd figure the best sponsors in allllll of japan would do something absolutely crazy and unthinkable like port the housings and put some better wheels in there (at least i'd ask for it)....

This isnt his only car. He has so many. Its not his pro car! Thats all HKS.

"how would a t25 be maxed out at 15psi"......does it hold 15psi all the way to 7,000 rpm?

Mine did even on a side mount. But i never took it apart so who knows!

i didn't see anyone say a t28 is maxed out at 15psi, i would say t28 should hold 17, sure crank it up to 17.4 psi for the quick .4psi of extra torque really quick (since you're drifting) and if it drops back to 17 at redline who cares, you clutch kicked it and the tires are already spinning.

They dont go by psi they go kg 1.2 = 17.4 sorry its the math.

anywho, being best friends with michael jordan doesn't make you an nba coach. the point me and some other people that said no need to go 20psi, was that the minimal gain isn't worth the extra risk. enjoy your car, if you want more power than your turbo's capable of, then upgrade your turbo, why push it till it blows your motor or the turbo takes a shit. that's all =]

Agree!

[Z U L8R]

john, so what's the point of boosting passed your turbo's efficiency? what's the benefits? what's the risks?

this is madness....madness??? THIS! IS! POINTLESSSSSSSSS!

do you think running 15psi on the stock sidemount is ok?
