Or in other words, your computer is telling them to pulsate, and all they can do is just dump fuel...

 

And having the injector open the whole time is a bad thing, right?

 

If you want to push it even more, you may need to take a real look at the control system. Others have already alluded to that.

TPI? Yes, it was a pretty cool indution system - Back in 1984.

 

I think he's a long way off from maxing out TBI if thats what you mean.

Your just out of fuel. Crack open that bin and post it for all of us to see. I bet we'll be able to find out some pretty interesting things from it. If anyone has an ecm bench we should be able to find out exactly where your running out of fuel.

 

well.... he does lack 45 cubes....

 

You're kidding right? My taurus lacks about 97 cubes (or about 142 from the 350) and ran about what he's running when it was stock.

He's not making excuses, and you shouldn't try making them for him. I think it takes away from what he really posted for. His tune is seriously in question and is what he should be looking at right now. JP has hit on probably what he has to do, namely get into the prom.

It's also not like it's a surprise to anyone here that TBI is not a performance platform, as we've pointed out while having some fun and as Vader succinctly put it, but you work with what you got (until you get fed up or score cash) and there have been some fun tbi cars built. :shrug:

 

It's not the TBI in any way that's holding that motor back. TBI is a speed density system and just like every single other speed density system it needs to be tuned extensively after changing so much on the engine. That tune is set up for the volumetric efficiency of an LO3 and it is definitely not an LO3 anymore, everything has been shifted around with the cam and the flow characteristics are completely different with the heads. If tuned right it will run right with any other for of induction. TBI won't become a limiting factor on that setup for a while.

 

Where exactly did you get that out of my post? The part where I said he had to get into the prom or are you extrapolating from the TBI not being a performance platform? Both statements are true, don't lie to yourself. The prom work will help a whole lot but... Most don't even consider TPI worthy of calling it a 'performance' platform.

 

I'm just pointing out that too often a bulid like this happens and TBI is blamed for the lack of performance. It definitely isn't a performance platform but properly tuned it has potential to support some decent power.

 

Ah. Ok. Mis-read it since it followed my post.

 

Id assume your Taurus is a SHO of the 3.4 V8 variety from your cubes reference. If that's the case, you already started out with 32V, DOHC, SFI and 6300-6500 (?) redline to help you out. Your 90's technology is better than his 80's technology; could you imagine if you had an extra 45 cubes? You already started with 60 more hp than he did. What was the trap and what elevation? What was the elevation of azvolfan's times?
No Im not making up excuses for him. I was merely pointing out an obvious distinction between two completely different engines to someone else in the thread. And yes, I agree he should look into the PROM because there's something seriously wrong. With those mods he should be able to reach low 90's traps and 14 second 1/4 times.

 

The cu. in. comment is always lame and that was the point behind my comment. We can all read. The SHO wasn't exactly state of the art 90's tech either. I'm more impressed with the second gen sho than the third gen in that regard. :shrug:

If you want to compare '80's' tech than I can point you to some nice 302 set-ups as well as 350, and 351 set-ups. Yes that would be Ford and Chevy, my only prejudice is speed.

There is too much in common with the 305 and 350 for you to say that "I was merely pointing out an obvious distinction between two completely different engines to someone else in the thread." (in reference to your 'lack of 45 cu. in. comment.').

And again, IMNSHO it was taking away from what he was attempting. Sort of like saying 'Dude, why bother, just yank it and pop in the 350 now'. That is by far not his current problem.

 

Ok, not to rain on anyones parade, but the argument needs to end now. This has NO impact/tech value what-so-ever for what we are trying to accomplish, so if anyone needs to continue, please take it to PM's. Thanks, and if anyone has any problems, you can take it up with me. (Again, in PM's ) Thanks...

I read it several times and it sure seemed to be the point behind your comment. You ran the same times as him with 97 less cubes so your engine is better than his.

Ummmm the only thing in common between the L98 and L03 I can think of off hand is the distributor and ignition components (minus ESC), thermostat and valvetrain assembly (minus cam and valves).

I think you misread my directed statement. I was not stating it to azvolfan in any shape or form and nor was I alluding to him yanking out his 305. If you re-read clearly what I quoted and what I said, it is not me who is telling him to yank the 305 rather the quoted person.

 

This was turning into a good thread on how tuning can be worth alot of power. Now we have about 6 pages of "dude" it's blah blah blah. Is there any way we can edit that crap out? I see alot of people skipping over this post because of the garbage.

Back to tech. Make sure you get that bin posted as soon as possible. I can't wait to see bad your injectors are going static. I went through this with my BBC TB and injectors. I had problems with the car just hitting a brick wall when the injectors went static. It seems like the smaller 305 injectors don't do this, they just seem to just quit moving any more fuel so you don't know when you run out of fuel, othe than the car quits making power.

 

iroc22 you didn't get it, it's ok though because those I wanted to did.



BM... we got ya already.

 

Ditto.
