Sorry no A/F ratio monitor on these pulls.

 

Take out the .org.jpg at the end of your link!

 

Was this at 8 PSI?

 

13psi

 

up

 

hm, numbers are kinda low dor 13 psi, IMO.

 

Bro I said critique, not,"hm, numbers are kinda low dor 13 psi, IMO." If you look at the dyno sheet you will understand that power was made at 5400rpm which is very decent seeing how I still have another 2500rpm to go. No Honda shifts at 5400rpm. Thats why I need peeps to CRITIQUE

 

he was critiqing

 

I would assume you are running with Steven's B18 Zdyne Tune moded to your fuel setup right? I ran his program on my Stock B18B and pulled 189 WHP/154 Tq
On 8 psi. I then when back to an old program I made while tinkering around and it feels a bit faster. Maybee you should try it. Or course make sure it gives your enough fuel + spark retard. But It made my car feel better. I don't have any #'s for though to prove it.

Your torque curve sure takes a dive after 5500... seeing thea/f ratio woul really help.

 

those numbers are real low for a b18b on 13psi heres mine at 14psi on a b18b using a 54 trim to4e w/ a stageIII .48 a/r housing.

 

He was critiquing. Anyway, sounds like you are satisfied enough with your results, so why would you need any outside input?

 

those were just baseline runs. mike, i'll bet you make more power with some wb tuning. hp shouldn't just go flat after 5500rpms.

It is a B18A, get it right! Like it really matters,
but I still think old LS motors are better.
B18b owners, your valve cover looks like one for a Neon..just playin'

 

I wanna critique , but It would help to see the air/fuel ratio vs. rpm graph.

 

94goldjungsr- The pulls were done without A/F ratio. It was a come as you come and take 2 pulls. But with the wideband the car takes a **** at 5500rpm because of the lack of fuel. So I upped my fuel pump from a Walbro 150 to a Walbro 255. and still the same thing.

DRAGLS- I know they are low thats why I posted my mods so if anybody sees any issues they could tell me something I may have overlooked. But your dyno plot looks good bro. What mods do you have done to yours?

degradated- The graph should speak for itsself. Obviously theres a problem or I wouldn't ask peeps to HELP ME OUT with this issue. I need answers bro. Telling me what I already know isn't helping me. I am not bragging about this by no means I am posting this so someone with turbo experience can see something in my mods that they may question and bring it to the front.

Quick 200k Mile Motor- I would love to show you but that was not a option that day for the A/F. But with the FJO I was reading 15.6 at 5500rpm so I was running lean from 5500rpm onwards.

This question is to everybody. What injector size should I go with? and where does the torque usually tamper off on a LS with my mods?

 

Whenever people have a problem making power, the first thing i always tell them to look at is their fuel. You need to get that thing on a wideband and get that a/f to 12:1 area. I think u definitly need something bigger then 440cc injectors too, try some 550's.

2nd thing. what size downpipe/exhaust are u running? what is your static compression ratio?

3rd thing. Ur torque curve is falling off bad. Your reaching peak torque later then me and ur torque curve falls off earlier. With cams and headwork your torque should stay alot more flat. your peak torque is right on par where it should be.

I would suggest right now to not worry. First thing I would do is tune the a/f. Then if things arent on par, id look into the possible weak links of the set up. first places i would inspect are intercooler, turbo and cams. considering those 3 things will have a huge impact on what the power curve looks like.

ill try to get my dyno's online asap so u can compare them.

Dam DRAGLS! How didn't you get those awsome #'s! What is your engine setup? Cams, headwork? intake manifold? I have a T3/T04E with a 63 a/r 54 trim compressor but not a stage III wheel. Also I see your A/F takes a dive 5,300 RPMS's And you still made awsome power! Tell us your secret!!

 

My fucked up Zdyne tune strikes again......will I ever live down my shame?

 

I think you just need some tuning and you'll make more power. Looking at how choppy your power band is thats all i can really tell. You need to get a Wideband on that thing. On my car on 9 lbs of boost with a stock B20 motor I put down 250 hp and 223 ft lbs of torque. You've got all the good parts, just needs some tuning. what are the dimensions of that grand Nat intercooler?

Updated, I've got an FJO test bed tune. It's not totally perfect but it works a whole hell of a lot better than that damned conversion I've got such a notoriety for....See if that helps any.

P.S. ~ 40Psi base fuel pressure, GM 2 Bar & 450cc injectors

Wow this tune sounds like it was made for may car. I have the same fuel pressure/2 bar map!
Can you send me the file. It's not working for me on the website.

Fixed

 

Thanks for for replies guys, this I really appreicate. First thing is first. I have to increase my injector size to 550cc, which a buddy is lending me to see if its enough. 2ndly I have to change my exhaust. I have a 2 1/4 exhaust into a 2" muffler in the stock location of a 91Integra out to a 2" tailpipe. My compression is 9.75 to 1.

Speed PHreak- bro its a learning curve forsure. But I am difenately up for the challenge. Keep up the tuning bro, practice makes perfect.

As for the dimensions of my intercooler, its 25"long 4"thick and 10" in height.

My last question I have for LS turbo guys is, what are you using to vent your crankcase pressure? Are you using the stock setup and a K&N breather on the valve cover? or catch cans and etc?
