Warning: To all the newbies and high school kids.....
Attempting to do what I am about to share will most likely result in a blown motor.

OK, since thats out of the way, check this **** out...A few weeks ago I wrote in about how I was using some basic mechanical engine management as well as some left over project car parts to use in my current project...Basically the only new edition to what I had before are a nice used set of 310cc injectors...For those that dont remember, my setup is a 93 eg hatch with a bone stock 1994 ls swap (mileage unknown of course), revhard turbo kit with a 60 trim precision turbo,2 1/2 in. exhaust, cm stage 3, blah,blah thats about it.....
I am using a fmu, in-line pump, 255 hp intank pump, 310 cc inj, and a msd BTM to pull timing under boost...With this current setup I am now able to boost (bite your tounge ) 15 psi on pump gas....My a/f under boost stays between 11.7-12.1, and by mecahnically checking my timing with the method I mentioned in my old post (air compressor/timing light) , my total timing under full boost is 16 deg....
Now I know many of you are reading this saying "this ******* is gonna blow his **** up" , but I am honestly really comfortable in saying I truly believe this car is running safe....I have done about 10 full pulls with the car tonight checking plugs in between each run, and they seem to look fine..No real sighns of detonation at all, and the drivability of the car is very close to stock...I am really stoked at this point, and I will keep everyone updated on how its doing with longevity and so forth...The engine seems to run well overall and has good compression, but other than that, well like I said I have no history on it at all....So If it blows the hell up, it very well could be from old age, tons of miles, who knows......... Just thought I would share since I am so proud of my old school *** right now......j/k Comments welcome as always...

 

No reason to Hate!

This is a Proven method of Fuel Managment!

if fuels good and timings good then u shouldnt be worried about blow n up

 

props for takin the risk and proving to everybody that old school management still works

 

I love people that like to do it themselves and prove others wrong...but you still could be doing it better (safer & more control) for much much cheaper.

Are you still on a stock map sensor at 15 psi

The map sensor won't see any boost using a missing link or equivalent.

Your are correct about the fuel management part, but I was more amazed at the timing control of the whole thing...The msd unit does work well when set up properly, but takes lots of tinkering with some trial and error to figure it out...

You are correct 100%, but for some parts that I allready had just kicked in the corner somewhere, it amazed me on how well they are working together... Driveability has impressed me as well also, no real issues there either..

 

again, it amazes me that you can get away with this ****. he hee g/l frank and take care. oh **** the clutch finally came in yesterday and thetranny should be goin back in friday. thats the only time i have. then i can start rolling on this damn thing.

 

Maybe i missed it, but how exactly did you go about checking the timing with air pressure?

Yeah, I didnt write my explanation again because there is a recent thread with me explaining it allready....But I will try to sum it up real quick for you...
Set base timing to 16 deg btdc..Then hook up your "home" air compressor to your boost gauge first and adjust the amount of pressure while looking at your boost gauge to simulate how much boost you will be running..Once you have that set and verified, pull the vacc line that goes to the btm and hook up your air compressor up to it....Now press the air nozzle down and dial you timing light back to see how much its pulling of your base...In my case I was tuning (tuning haha) for 15 psi of boost so I verified that I was pulling exactly 13deg of timing off the base...Subtract that from 29 deg total, and I now have a new total of 16deg under full boost... Kinda gangster, but its been working for quite some time now ...

 

Gotcha, just making sure you weren't taking that the reading at idle and not realizing that timing advances with rpm.

Haha, Thats why the first thing I said was my warning to all the newbies, because I know there will be people just starting out who want to try this crap...lol Yeah, if I was going off the base @ idle, I would have a post up today sayin:::Why did my stock motor blow @ 15 psi with an fmu???

 

Anyone with boosted stock ls motors care to share there total timing at boost levels of 12 psi and above???

20* @ 13 PSI (T3/TO4E .63..50) On C16. Bone stock LS w/ over 150K mi.

It made 233whp/212wtq on 7psi @ 23* on 93oct.

Damn dude, needed c16 on 13 lbs??? Or were u tryin to be extra safe or something?? You could have gotten away with runnin about 25-26 deg on that boost level (w c16)...I used to do it all the time on my old ls motor, oh and I got you beat in mileage @ 170k +... haha Thanks Phil

 

Just a little update for you guys....Car is still runing strong beating the living **** out of it as always!!

 

Kickin a$$ and takin names still

Always had respect for your ghetto glory, keep it up mang

haha, thanks man...Yeah, everyone knows how to tune a hondata,neptune, aem, or whatever safely and I am sure one day I will step up and get the real deal done..But for now lets see if this homemade gangster **** will hold up on my 12 year old stock TMU motor!!!

 

I ran my stock motor at 20-21 degree's at 14 psi for 2 years no problems till I got my build done.

It made 300whp and 290 torque to the wheels fun setup and it lasted.

What engine management though???That seems to be the norm now a days with a good tuner..

 

Well another month of running strong!!! Tracks gonna open up soon!!! Cant wait to get a new time..!!

 

Just a question....dont most people with fmu's run stock injectors? Whats your fuel pressure?

 

You're my hero

I'm using a BEGI FMU running ~5-6psi on a stock h22. I don't know much about timing, but I assume you use the MSD BTM to retard timing to keep from detonating? I have a wideband to keep track of my A/F (staying around 12.0:1 under boost), but I don't have any idea what the stock timing looks like on an h22 (I would assume it's fairly advanced?)
