14b Limits?

[screwdgie]

Well my plan as of now is to run a mid-high 12 with the 14b, stock cams, stock injectors, and stock intercooler. Many have told me it can't be done, but I am sure I can do it.

My first question is, what should be the most boost I can safely run with the 14b on a 190 pump? My guess is about 17-18 psi. Of course I will log it after I install it , but I want a general idea.

I am currently having a boost creep problem so i bought the dpconcepts boost creep kit http://www.dpconcepts.com/BoostCreepKit.html. I am also in the process of getting ahold of a 7cm ported exhaust housing. ( I dont want to hear any stupid comments about the boost creep kit because i have heard from some people that tried it, and it works for them. Plus its only $30 so either way i dont care)

So I am trying to get rid of my boost creep .

My temporary plan right now is to run about 15 psi on the stock clutch, then when i upgrade, turn boost to 18. Of course only if i can keep my knock down.

Also, what is the limit of the 14b in terms of power / boost/ 1/4 miles times? I know someone has ran a 10, but Im not going that crazy.

Thanks for the time,
Shane

First off, that "boost creep kit" seems like a bunch of BS to me. Run an o2 dump housing and you won't have any creep issues. My 14b has a 7cm housing with a stock size flapper door and it holds boost where I set it. I run 23psi on it, and it'll drop off to 18psi by around 6k. Your 190 pump will be more than the 14b will ever need. I use the old Denso 150lph, which flows about the same as the Walbro when rewired. I've gone 12.1 @ 112 on my setup, with HKS 272s (which probably aren't really helping since the turbo falls off at 6k) and a Dejon big SMIC. I went 12.4 on the stock SMIC. I believe there was another guy awhile back who went 12.1 on a 14b with stock injectors, cams, IC, and I dont think he even had an AFC or anything! My best advice is get a logger and a charge temp gauge. Tune for the most boost you can run without excessive knock in higher gears and make sure the charge temps don't get over like 150-160.

FWIW I was overrunning my injectors at 17lbs on my 14b.

 

[LaN-]

14b limits ???? HA the 14b has no limits (evil laugh)

a buddy of mine should do high 12's this spring at 20 psi tuned, and we all know the 1g FWD that went 10's on the 14b

how do you plan on runnign 18 psi on the stock IC and injectors????

how the hell do you go 12.1 on the stock injectors and ic????? unless you have some type of meth or alch injection or something i dont see that being possible

2 words...

Race Gas.

Steve 93, that kit may seem like bs, but a few people have told me it works, plus its only $30 so i figured i'd give it a try. I am working on getting a ported 7cm housing right now. I almost got an o2 dump, but went with the evo3 because I got a great deal on it, plus my neighborhood hates how loud my car is already .
I have a logger, and I dont know how i ran without one, i love it! .

What exactly is a charge temp gauge, I've never seen one before. I know the logger can read intake air temp, but thats at the maf. Is this gauge something that you can tap into the uicp to measure temp there?

How much boost can the stock side mount handle before it really starts to heat soak?

I am also thinking of switching to a maft in the future, since its a breeze to install and easy to tune with. Not to mention i can vent (for the ricer in me ) haha.

Thanks for the help guys.

With enough nitrous, the 14b has no limits.

 

[screwdgie]

Nitrous is out of the question for me. You can make any car fast with enough nitrous .

 

[Coup D E'Tat]

FWIW, DSMLink estimates 256whp @ 15.5 PSI with 20* peak timing. I'm going to up timing a tad more in some areas, and see if I can pull some more power out of it at that boost level. The turbo is not mine, so I will not turn the boost up.

 

[tstkl]

im hoping for a 12.9999999 or faster this feb 20th when i go. ill tell you what i get, but this is what i have:
dejon 3 inch exhaust with no main cat and two straight through "mufflers"
full dejon upper and lower intercooler pipes, short route style for my jrc 8 inch fmic.
a dejon intake pipe with a k&n 9 inch air filter.
a gm maf mounted on my uicp.
and a dejon smim.
along with a 3000gt vr-4 fuel pump, im going to dump a lot of race gas in there and pull 22 psi max. ill take some runs at 20ish first. only tuning will be with the maft. home made mbc will be guessing 20 psi on the way there.

wish me luck. my 14b is completely stock, along with everything else not mentioned. (except a few non performance things. had to get a different power steering cooler to make room, that kinda stuff.)

 

[screwdgie]

tstkl, you should have no problem running a 12 with the fmic and smim. Put some cams in there and you'll notice an even bigger gain. By the way, how do you like the dejon smim?

If I keep my car long enough, and AFTER I run a 12 with the 14b, stock ic, cams, and injectors, I want to switch to a maft, 550's, bigger side mount and 264's and shoot for 12.2-12.3s. I don't think I'll have any problems after I get it tuned.

Why would a SMIM help a turbo that dies past 6 grand?

 

[screwdgie]

Well the dejon smim is designed to improve mid-range and top end power. I would consider mid-range and top end power from say 4000 rpm and up. He's not running down the quarter mile above 6 grand the whole time is he? Anytime you improve airflow in the motor it will make more power, or at least have more potential to make more power. Of course he would see much better gains with a larger turbo and more aggressive cams, I'm sure the smim won't hurt him while running the 14b.

 

[Dream On]

Take some weight out of it if you haven't already. That'll help a little.

True, but the stock intake is much better matched for a 14b. The stock intake will outflow SMIM's in the 14b powerband.

Yea, Buy c16. I ran 24lbs of boost on my 14b with stock injectors etc. I ran a 13.0 @ 107my first time ever racing, spinning all for through first gear..

 

[screwdgie]

1993eclipsegs- Did you have any other mods done when u ran a 13.0 @ 107 on the c16?
Also, did you happen to log the car while running the 24# of boost on stock injectors? It would be interesting to see exactly what was going on during that run.

Also, where can I get some c16 from? I don't think the track I go to sells any. ( GLD)

 

[1993eclipseGS]

I made 12 passes one after another and only get faster through out the nite, Resulting in the 13.0. I did not log the car, I know i know(no one hasto tell me how it wasen't safe. I just turned the boost up until I hit fuel cut, Then turned it down a turn). It got lowered back down to 16lbs when I drove it on the street again. The car had a fmic and an exhaust. Although you can unbolt your exhaust.

My friend ran a 12.7 with a boost controller, unbolted exhaust, And an open airfilter.. As long as you get a very good lanch, You're on your way to good times.

 

[screwdgie]

Wow, pretty good runs. When I race next time, I am gonna try on pump first, then on race gas at the same boost level, then turn it up a little just to see what kind of difference it will make.

 

[1993eclipseGS]

Definatly if you buy race gas, Take advantage of it. Turn the boost up!

the smim was purely because i didnt want to have to buy a new uicp when i got one later.

i regret that entirely. not because of dejon, because of the dealer/myself.... I wouldn't know how any of my new parts perform, as i just drove it for the first time since august the other day. -10 hg/in at idle. at least i drove it to newlogics to get it fixed.

after this im redoing the clutch, fuel system, getting dsmlink, and getting a pte dual ball bearing 57 trim. then it will be 11's or bust.

only thing im worried about are my skills (never dragged before and havent driven the talon hard since before last august) and the stock clutch. hopefully i wont be trailoring the car home due to a blown clutch....

 

[screwdgie]

On average, how much does race gas cost?

 

[DevilSperm]

i ran consistent 12.80's on a bone stock 14b at 20 psi, stock injectors, stock SMIC and MAFT, with no engine work done. Upgrading the injectors and intercooler stuck me in the 30's. I will run this 14b until its completly toasted

 

[screwdgie]

30s? As in 30+ lbs of boost on the 14b?? When would you hit full boost? What injectors were u running?

 

[tstkl]

12.3x not 30 lbs
