Drive it around so its good and hot and weld it hot.
It'll hold.

 

where is this "devastation" you refer too??

 

those volvo turbos arent big enough to push the motor even with the nitrous, they will only support 250 flywheel hp so once u exceed that ur really only over pseeding the turbo and pumpin very hot air into the motor.

if u can try to find some t04 turbo in the junkyard or check out ebay for a used t04, or hell just buy a china knockoff t3/t4 nw or 130 bucks

 

Patience, my friend, patience.

It's actually a t3 off a saab that's supposedly good for 300hp. I've been scrounging the yards for a diesel international harvester so I can put together a t3/t4 but no luck. I might just put another turbo in series so I can blast this f-er apart. Either that or I'll just dump n20 in neutral.

 

i had my old 2.8 on 300ish shot retarded the timing 4 degrees with 2 step colder plugs. went 12.8 at 110 with a one tire fire still didnt hurt the motor, actually the motor is in a turbo fiero now(totaled my old camaro)

these motors can put up with alot its actually a little crazy that i never blew it up. had the spray on it for a year or so going through 3 or so bottles a week

 

making me question why I would spend all I have to be limited to only 5-7 psi when I could spend the same and choke it with 15-20 or a 100-150 NOS shot and not worry a bit.


bl85c & turbo2825psi what all did you do computer wise to run that big NOS shot & bl85c what did ya do to run 20psi of boost?

Im guessing stock computer config, with a wet NOS system

 

No, I'm doing my own coding with the '165, 6E mask. Something like BAUJP for maf cars. And only 15 lbs. Read the first few posts and I explain that the nitrous is controlled by the egr output.

 

Look for 80's Mercedes, they have AirResearch true t3's, nice sized turbines sine they are diesel, won't choke the engine, and have the same sized cold side as a large t3 Garrett on a gasoline engine.

 

OK thats kinda to bad, I get your plan, your trying to blow it up but your tuning beyond stock so it can't go early.

Would be nice if your explosion project found the true limits of the stock computer system

In any case you need a how to for ubar dummies write up so folks can dupliciate it to those upper limits.

 

I'd read it!

 

holy crap, holy crap, holy crap, HOLY CRAP!

im done now, btw did i say HOLY CRAP!

 

I usually don't do writeups on more involved projects. My opinnion is if you don't already know or you can't figure it out you shouldn't be doing it. A long as I'm writing my own code there's really no limit to what the pcm can handle, the hardware is the problem. Luckily I have a Z06 maf waiting for a later project.

 

That's why school have teachers and not just a room full of books with instruction to just figure it out yourself.......

Its not always that simple for everyone................

 

bl85c what you should do is market it, if you can do it semi cheap and still make loot for other projects.

Buy this this n this, load this program, wire this, this n this here, now go crank up the BOV psi and open the bottle.

That type of performance gain on a stockish V6 is what folks want in a "bolt on" over re-doing engines.

 

Well I am going to release the power adder version of 6E I've been working on for this project after it's nuked and I'm certain there's no glitches. It will be set up to allow someone to take a basically stock 2.8 to 15psi, with or without intercooler, nitrous, ect... I'm trying to put as much foolproofing into it as I can before release- especially around IAT based spark retard. And whoever's interested can have my setup (or what's left of it LOL) after I'm done- turbo included.

On another note here's what I'm trying out now. It's an IHI off a thunderbird. Supposedly good for 15+ psi, but so far I'm not impressed. The t3 felt way better, power came in sooner & continued to climb with speed. This takes too long to come into boost & just isn't thrilling. Still looking for a t4.

 

DIBS

 

You suck!

 

.

 

45 minutes tooo late

 

Any updates?

 

Awesome!

 

Wee! Diesel mercedes turbos are fun. Power comes in... abruptly.

Still trying to figure out what's wrong with the spark control. Fuel mileage really sucks when you cruise at 20* of spark.

 

Spray it with 300 lol

 

Lol, probably because of the low RPMs diesels have, but not sure.

 

GEIB HER TU M3H! I SABE H3R!






English translation: "Give her to me, I'll save her!"

 

Well a 200 shot with 15psi seems to be the limit. I can't get it to stop knocking and it's not lean. Maybe too much spark... but I only have 20* at full hilt. Fine at 6psi & a 200 shot though. At first I thought it might be false knock but the plugs have pepper specks. I'm going to finish up the code changes to 6E so I can release my power adder version and hopefully get in a few passes down the track before I do this thing in.

 

Get a supercharger like that ludicrous one this one first gen has...its bigger than the engine....blew the head gaskets out and lifted the front wheels an inch when they started it lmao

 

Retard the hell out of the timing and jug it with a 300 shot.

 

My Sky and Cobalt go from about 1 degree advance and ramp up to 15 degrees by 6400rpm when running 22 psi. They're direct injected, have 9.1:1 static CR, and vvt if that makes a difference. At 14 psi in my camaro I ramp the timing from 11 at peak torque to 16 degrees at 6000rpm (9.4:1 static and small cam). Moral of the story: retard the timing more.

 

Is that with fastburn heads?

 

yes, 96-00 Iron vortec heads.

 

Haha I've seen that... I wish they got the engine running on tape.

I was on the understanding that the Vortec heads are more considered open wedge heads than fast burn, their shape is quite diferent than the lsx/3x00 etc "gen 3" stuff.

You are where you belong.

 

Wow, 3 posts and he's already banned. And somehow he doesn't understand that the whole point of this is to develop some useful code for maf users then destroy the motor.

 

Don't know ow I missed this post, but WOW! QFT!


You want late model heads on your car, bolt them up and see what's lacking. It's so stupid simple, it get's comical when asked for a parts list or "write up".


Searching is where it's at...

 

Keep in mind that while it may seem simple to us because we have nearly daily contact with things like this in our professions, it is intimidating to an outsider who hasn't had a chance to form habits & gain enough knowledge to just jump into projects like these. Which is who I feel the average v6 owner is. That said I also believe that you can't form those habits without doing it yourself. There's always examples of what others have done and people to help you along the way.

 

So true Sorry about the rant, let the animosity spill when I visited here after another forum where the members know better and ask the same things over and over. After working over the top end and enginge management of my daily '86 BMW the past 2 weeks, I should have realized that most members here are modifying their daily drivers as well and should be a bit more sensitive.

I apologize for the previous statement...

 

Damn. I had to castrate my car. Tech didn't like my nitrous blowdown tube and they made me take the bottle out, so I decided to turn it down to 6psi to be safe. Totally got raped down the track too. Only got 2 passes in and the first was a 15.149 with a lethargic .557 reaction time! Second was a much less embarassing .052, despite that I was actually slower because it was so damn hot so I hung it up and went home. Took a look at the log when I got home and the mat recorded almoast 200* at the end of the run.

I lined up against a 3800 4th gen the first run and we were pretty close. Second was a diesel ram that had a 1.7 sec 60' so it was pretty comical.

At sea level I would have run 13.97 at 97.65 so I'm not completely disappointed but I'm definately looking foreward to next week with a hardline blowdown tube!

 

Can't wait to see what's next

 

bring that thing down here...they don't make you go through tech for test-n-tune nights/days! lol. atleast you made it to the track, good luck next time out.

 

Patiently awaiting results...

**taps foot***

 

Death is the result! Nitrous backfire killed the show before the '330 mark.

After some research and messing with alot of e.t. calcualtors the nearest I can figure is that this would have been a 14.3 run, which would have been 13.19 at sea level. I had a 1.943 60' and a 5.88 at the 330' mark. The 330' would have been closer to 5.5 if that nasty fireball hadn't blown the induction off. I knew it was bad news right off the line when I felt a bog, then it ran like a bat out of hell just before the pop. I'll have some pics tomorrow when I bring it into the shop. Not sure if the game's over yet for this motor but I'll find out soon. Man did it make a big cloud down the track lol.

 

Oh, and this was at 10psi with a 200 shot. I'm hoping the induction mess was the worst of it and I can still put this through more abuse, but it's kinda right on the edge of where I ran into knock before.

 

If you aren't breaking things, you aren't trying hard enough

Kinda slow 60' with the power adders, but it looks like you were making up time haha. Our race car does a 2.4 60' and still manages a 13.8 or so at about 119 - it's a road-course car (500/750lb springs, 270whp@2100#).

Got pics? Carnage is always nice.

 

The nitrous gradually slopes from 10% at 2800 to 100% at 4000rpm so I don't blow the rubber off the tires on launch. 225 wide street tires. I've been searching for something wider but there's a big gap from 225 to 305 tires for 15" wheels. Really frustrating when almoast everything had 15" wheels at one time and now nothing . Guess it's time to upgrade.

Good news and bad news. Good news is the motor survived. Bad news is the motor survived. Daylight revealed that the damage wasn't terrible, basically just blew half the throttle plate off, ate some plugs and shot the bov across the engine bay. Sounded like a shotgun. The rest of the throttle plate must have shot out with the bov because they're MIA. I took the manifold off and opened up the turbo to be sure. Compression is fine so no bent valves and I didn't find the plug jackets so they must have shot out the exhaust. No damage to the exhaust side of the turbo but I did find some ceramic dust when I took the downpipe off. After I grab another throttle I'll be able to drive it home tomorrow.

 

.

 

There's the flavor.

...you might be able to just get away with a new tune for your throttle body, haha.

 

Maybe if I retard the timing enough I could get it to idle at say... 4000rpm lol. When I pull up to a stoplight I'll just let it do a burnout until the light changes.

 

LOL!

So, you will be launching at full nitrous, w00t!

 

That was one heck of a back fire, guessin the plate was shut when it went off, making it make a hole to escape?

I blew my intake tube apart a good foot behind the MAF and put a quarter size hole in the exhaust pipe by the rear wheel when I had my hickup a few weeks back on the eway.
