Tan top max HP
I PROMISE i searched
I got a lot of different answers The anserws I was reading was 7.5psi on the greddy 15g? but im boosting 10psi, 12 to 1 rise rate disc, highpressure fuel pump and a front mount I initially started the search to see if i can bump it up to 12psi on my t25 turbo (figured its so tiny) itd be cool if i can get some personal opinions And please, i know, Megasquirt, but its not in my budget yet :( EDIT Either max hp or psi on that turbo in particular |
|
What should I put for fuel consumption
|
with .50 fuel consumption, it says im good for about 300bhp, is that possible? how come people were saying they were 100% duty cycle at only 7.5psi on the 15g when im running 10psi on my t25..
|
You may actually want to read the information that is prominently placed nearly at the top of the page for answers about BSFC.
Secondly, the 15g is different from the t25G and it's fuel consumption. |
I dont see anything about fuel consumption, and yeah... im aware they are different turbos, i was just stating the names because i know you guys would flame on me and what my setup/turbo is, etc.

Selecting the Proper Injector Size In order to select the correct size injector for your application, you might wish to use one of the following formulas. In most cases a naturally aspirated engine will have a B.S.F.C of .50. This means that the engine will use .50 lbs. of fuel per hour for each horsepower it produces. Turbocharged engines will want to be at .60 lbs. per hour or higher. Using these numbers as a guideline, you can select the approximate injector size in the following formula for a four cylinder, naturally aspirated engine at 200 bhp. Most injectors will max out at 80% duty cycle and this is the accepted industry standard. B.S.F.C is brake specific fuel consumption - How much fuel you are using per horsepower per hour |
Okay, so the 300bhp is correct, but does that seem right?
|
You should PM Hustler and ask his advice on this thread.

300bhp requires 640cc injectors (BSFC of .65 and a max DC of 80%). to get your current injectors to flow 640cc's worth of fuel you need a fuel pressure around 340psi - stock is 43.5psi, NOT going to happen... I worked all this out from the RCEng site. Search more, and actually read what you've searched! |
Basically no matter what you do you wont go over 180 or so.
So start saving up for MS and injectors, and leave current setup alone before you melt a piston |
Dam, i was hoping for some head room, im currently trying to find injectors as we speak, ill try to message him
|
With stock injectors on boosted car you are already using the "headroom".
305's will get you into the 200-220 range max. Anything more you need proper management and proper injectors, unless you want to be stupid and run a hackjob setup with extra injectors and whatnot |
are you kidding me hahahahahaha i can run what, 6? 8? injectors hahahahaha id want a set up of 8 tan tops lmao you just blew my mind man
|
You've never seen the FFS kits have you?

ill look up the ffs kit right now!
its an expensive supercharger lol what about it though |
:facepalm: nevermind. not wasting time on this
|
so dont bring it up?
|
STFU and GTFO stupid noob.
Next time research a topic before starting a stupid thread about it. |

Get 3 big bottles of this:
https://www.miataturbo.net/attachmen...ine=1337891699 Den turn boost up to 15.75634807psi. Don't go over that or it will go lean. |
yes, boomboombambam, all of the info you've stated is correct. Don't listen to these fools.
|
Use 16 blue top injectors and NOZZZZZZ! (that's NOS for normies like yourself)
|
Lmao, i did god dam. like 3 different threads said 7.5psi with a 15g though, but i dont see how im running 10, that was the question, and yeah i did research, your just being ignorant. its fine if you dont want to share info, idgaf, but dont bring something up if you wont explain it lol thats just rude. and again, I DID SEARCH.
|
Im really not a bad guy, i dont mean to be rude or anything of the sort, but man, some people suck at their real life, so they try to moderate the crap out of a forum, grow up

Bambam... the variable that I haven't seen mentioned in this thread yet and that is critical to how much power you can make is FUEL PRESSURE. You are not running an ECU, so really the only thing you can control is RATE OF RISE and FUEL PRESSURE.
I ran well over 130psi at the injector for a long time before I got myself a fuel pressure gauge and actually went to a dyno. With my SR20det T25, tan-tops, Walbro 190lphHP, 02clamp, and Bipes... I ran 90-100psi fuel pressure at 14psi boost for the flattest AFR curve I could manage. It was far from flat, but it was as good as bandaids get. That was good for 210whp. I stepped up to 310's and it made zero more power, but I could run slightly lower fuel pressure. YOU MUST GET A FUEL PRESSURE GAUGE. YOU MUST GET A WIDEBAND. Now you can tune on the street. When you AFR's are as flat as you can make them on the street, get to a dyno. Oh yeah... the Greddy fuel pressure device is archaic as far as AFPR's go. Get a used Begi 2025 from the classifieds (or buy one new), and get serious about your tune. With the Begi, you can dial in base-pressure and have an adjustable rate-of-rise on-the-fly. You don't need to swap in discs, so you can do a pull, check your shiz, and use a screwdriver to dial in more or less fuel pressure, then do another pull and check. It's really the only way to go if you're stuck with bandaids. |
Thank you so much samnavy, you honestly just answered my question cheers!

That your gonna hate? Keep it coo lol this is how people get shot. Did you seriously just say that? Is that a threat? You know your personal info is right here for everyone to see right? Name: Jonathon Location: West Sacramento Telephone: 9165888263 http://images.craigslist.org/5Ne5Id5...81558c1896.jpg Bet that I'd say the same exact words to your face that I'm saying in this thread, and you wouldn't do ---- about it. See this isn't about getting into a pissing match. This is about every stupid noob like yourself always running their mouth on the net then saying "You wouldn't say that to my face".....Well guess what? I would. So either lets find out, or don't make the comment in the first place. If I were you I'd just stop posting in this thread. Period. You have failed. Good day |

not one thing off my car is from denios or autozone. Only dumbass here is the guy who made a name just to talk ---- at 1am LOL
|
But seriously, you guys should keep it coming, its quite entertaining. Im using all these come backs of yours on the honda forum.
|
And sorry that you paid 3000 for your kit then i did
|
That looks like diarhea
http://images.craigslist.org/5N25Ke5...905eb01652.jpg The worst builds on here have nothing on your POS. And since you look like ronald mcdonald it all makes sense: white car, red bay, blue coupler. Put some lipstick on the valve cover and you're set. I wonder though: do you want to actually meet? or are you going to keep running your mouth on the interwebz? lol bitch |
