but what should be my max boost on 370s

kojiki88 · 02-17-2012, 01:19 AM

Before upgrading to Cams and more boost I was running your similar setup at 11psi and it ran just fine. You wouldn't want to go any higher then 11psi since you're already flowing more air with the T28 then you would with a T25.

ahan thats seems fair amount of boost plus m on avcr so i really dont know how to play i have set it to .65 and gain 30 percent throughout so any help over here would be appreciated aswell . i am running 130lph fuel pump with 40 psi fuel set at fpr and v power 7 plugs gap at .30

kojiki88 · 02-17-2012, 01:37 AM

IDk about your fuel pump, I have the walbro 255LPH and if I remember seeing it correctly Mine is set at around 43psi at the FPR. Again Im not sure but either way my setup isn't stock anymore I have 740cc Injectors and Z32 MAF. I would just upgrade your fuel pump to a walbro 255lph to be on the safe side and if you ever decide to upgrade you'll already have a good pump in there.

it is same as waqlbro 255 but yours is in line mine is external i was using 044 pump before on same setup i was blowing alot of fuel and pig rich smell of fuel so when i just swapped this no more pig rich but some one also should tell me the setting of avcr ......

kojiki88 · 02-17-2012, 01:59 AM

Oh ok my bad I didn't know. And sorry I don't know anything about the avcr. Good luck.

no prob at least you give me some feedback which will help me a bit on boosting

zurud · 02-17-2012, 02:23 AM

Do 30 psi for a while like 1 hour straight . See what it will do. Then increase to 45 psi. Make sure to take video and post it here

RedSiBaron · 02-18-2012, 12:14 PM

Im sure with limited changes you can hit 270/280

Id get together with a tuner with sr experience and work with them on tweaking your build

nomoremk2 · 02-18-2012, 01:03 PM

So from what I gather you're slapping on a bigger turbo, not tuning and asking a bunch of dudes on the Internet what boost you should run? Goodluck dude.

kalypso123 · 02-18-2012, 01:25 PM

cool car, throw some chromed steelies on it. :0)

*fliprayzin240sx* · 02-18-2012, 03:56 PM

Leave the boost where its at if you're still running the stock ECU/tune. When you get your AEM, get some 740s and Z-maf, should be able to boost 18 psi on that S15 turbo and get you up to about 310-320hp.

leave it at wherever the factory wastegate is set at

you can get away with 10-11 though, I would have a wideband in though.

zurud · 02-19-2012, 06:38 AM

S15 come with 480cc injectors on that turbo. stock wastegate. Do the math. 370/480 +*/\*//*//*++

nismoracingsx · 02-19-2012, 07:08 AM

Read....read the post...
He said redtop w/ t28...
So no 440's....
Jesus, for the people smashing on him just b/c its so cool, you think you would read the damn post.

To the original poster, thats a pretty clean car, man. Props on the sleeper.
I would definetely avoid going near 1bar on those small of injectors, and the others have already iterated about your MAF also being a limiting factor. You can look through the For Sale section on this forum, people are selling larger injectors all the time that you could match up with your AEM/Map setup.

But for now, I would honestly just listen to Big Zee, leave it the wastegate set where it's at. Good luck, and keep us updated!

slim · 02-21-2012, 04:05 PM

I kept mine at the 7 psi. Never went lean on me but after 10 psi the 370s are maxed and it only takes a second to melt a piston right? I just played it safe and waited till I got my 440s.

its becuase i have hks wastegate on it so its set at 11 psi otherwise ill lower the boost ...

daftphunk · 02-22-2012, 04:23 PM

I have a s13 blacktop with s15 t28 and stock injectors. Running like 12lbs of boost and I don't lean out. At full boost my AFR is reading ~10.8.

Yeah it'd be wiser to get bigger injectors and a different maf. Up to you!
