how much power on 12 psi?

Post by **rtsol** » Mon Nov 10, 2003 9:17 am

what kinda power are you guys pulling at 12 psi? i just wanted to do a lil comparison on the ca vs. the 4g63. a buddy of mine just finished his project, and got 366hp at the wheels on only 12psi. thats a good 200hp more than you guys right?

stock turbo? mods? condition of the motor? This all plays a VERY important role. I'm sure 12psi on my stock T25 is less than 12psi on the S14 T28 that I'll install later.

i could run 12psi on a turbo off a tugboat and make 9 times that power. its all about the cfm of the turbo.

That guy didn't pull 366hp off a stock 4G63 turbo! A KA24 with a T4 turbo and some good on the edge tuning may get close, but no 2litre or 1.8litre is going to pull this off at 12psi and especially a stock turbo. Stock eclipses came from factory running around 12psi making 195-210hp in stock form. A CA18DET with a stock T25 at 12psi with the way some of the normal CA18 newbies do things, may yield around 200-210hp and that's granted you got a decent intercooler and know exactly what it takes to put this engine on the brink.

Dee, my friend is looking for a CA (complete swap, like mine was)

Anything down there in Miami?

The next CA18DET swap I get my hands on goes to another board member who have waited patiently for 2 months. The engines are not in abundance like they used to be, but they are attainable. I ordered 5, so let's see what comes in the next container or the container after it.

ok, you got me. this was on a fully built motor, 272 cams and everything. hes running a mild first gen upgrade a 20g i think. he also hits full boost under 3 grand, so this turbo isnt exactly huge. i just thought it was really impressive at only 12 psi-- thats stock boost for that car and it makes about 200 more hp at the wheels.

not even a 20G at 12psi... somethin bigger maybe. Hundreds of people run 20s. Results nothing like thisfull boost under 3k too ? 20Gs don't. doesn't sound rightNot many DSMs run 12psi

Post by **boost_boy** » Mon Nov 10, 2003 9:17 am

Quote »Not many DSMs run 12psi[/quote] You're right! They start at like 14 or better. And I agree that he is running something a bit bigger than a 20G.

the car was tested and tuned at turbochargers.com. they said that they had never seen a car make that kinda power with THAT boost on THAT turbo. they said that its exceptionally strong and has ALOT of potential. i know its a 20G but could be a different version like the "BIG 20" or sumthin. the same turbo spooled at around 4K before the build. before he thought he was making about 350 crank HP (the block suffered from crank walk and thats the HP level it usually occurs at) , this was on a mostly stock setup. he had a fmic, injectors, the 20G, turbo elbow, DP and exhaust. with that he was boosting i think around 20psi. now he has like 100 more hp with half the boost. ill try to remember EVERYTHING he has done:

god knows what else

i might get me one uh dim DSMs. they fast as uh spotted a$$ ape.

EDIT: hes only running 12 psi to break in the motor. when its broke in he'll dyno it again for 30 psi. here comes 550 ALL WHEEL HORSEPOWER!!!!!!!

I use to be a DSMer; sounds like a hahn racecraft setup using a super 20G (ball bearing). Turbochargers.com sound familiar, I think that is the place contracted to sell hahn's turbo kits. On 12 psi I know he cannt net those numbers because the first gen dsm's ran either 10 or 12 stock and due to the new head in the second gen dsm's they uped it to 14 psi to net the same hp#s as the first gen (why second gen swap on the first gen head). The average boost run on these turbos is 16-18 daily and arround 20-24 at the track with the internals and headgasket done.

i think the cams and venom intake manifold can attenst to allot of his power gian, there was a turbo mag project car that made i think 20whp on just the manifoold upgrade eh?/ and cams could be another 15whp or so, so thats 35whp there, and remember hte 20g is similar to the T04E so it could make 340whp on 12psi with good supporting mods, and he could be running high compression pistons (9.5:1) the lightweight flywheel could be freeing some power too i think turbomag picked up 12whp from the clutch/flywheel combo..

so i think it is possible.. i would like to see more detials though.

engine management ?Since he's obviously a seasoned DSMer, he must've posted a thread on dsmtalk, dsmtuners, NABR, or elsewhere. Comments from the veterans would be interesting, at least. I, for one am curious.

I doubt he'd see 550whp even from a td06H 20G... full spool under 3k? no way

I like the turbochargers.com Garret cover on the mitsu turbos. Slowboyracing.com sells 'em too.The Hahn racecraft 20G seems to be a good piece too. The very controversial 10cmm turbine housing eliminates the creep issues that plague the DSM 6 & 7cm housings and the spool only "a tad" slower, but more than makes up for it on top end. This according to ACTUAL users.I like the mitsu turbos. Durability and performance provenYou apply the same DSM mods to a ca18det/s13 and I'd bet the results are equal to better.

Quote »I doubt he'd see 550whp even from a td06H 20G... full spool under 3k? no way[/quote] 20G wound up to the brink of destruction, maybe 500. Would have to be a 25G or similar and since he said stock compression which is 7.8:1 on 1st gens causes me to raise my eyebrows in disbelief. Anything is possible, but with 7.8:1 compression and 12psi of boost, that much power cannot be easily justified on that motor. And before one assumes that I'm doubting, please read this post carefully. I though about the mods and took everything into consideration and can only conclude that that turbo would have to be a bit bigger to help create that much power on an engine that has forged stock compression pistons.

ok, hes not too much of a internet guy, but ill try to get him on here and explain. the turbo he has is not ball bearing. the pistons are around stock compression, i know its lees than 9:1

Post by **rtsol** » Mon Nov 10, 2003 9:17 am

confirmed: its a super 20G non BB. full boost is at 3500 not 3K(im sorry that was my mistake.) this car stock was at 12 psi not 14. i wasnt trying to say that he'll make 550hp on that turbo, that will be replaced for the big numbers. stock engine management with a apex safc. any more questions?

Post by **Trigger** » Mon Nov 10, 2003 9:17 am

who needs questions but get us some pictures and a dyno sheet that will settle it all

Post by **Guffed** » Mon Nov 10, 2003 9:17 am

yeah...12 psi makes no scense...with 3 inch and intake which im sure he has, the boost creep right there puts him probably to 14 psi.

how much power on 12 psi?
