So with all this being said would it be safe to say that:

On the stock injectors you should not run boost in a 4.3?

Possibly by overworking the injectors to 105% isnt there a chance that they would fail at any given time?

If you added an inline booster pump, as well as an intercooler and meth inj, increase the timing just a tad, run cooler plugs, and high octane pump gas, do you think that it would break the 300hp mark?

And finally does anyone know what the main contributor in driveline loss of hp would be?

Edit: sorry for the 32 type-o it was late...

you can run boost n a 4.3 but i would stick to low boost like with most supercharger applications. running a injector @ 105% duty cycle your asking for it to clip. i would not even try to squeeze out 300hp with the stock injectors in place. the pump will give more pressure behind the injectors but they still will not flow the desired amount of fuel so you will still run into clipping problems. maybe with the meth you might have a chance. but why risk it when you can just set it up correctly the first time. or run low boost until you feel you want more and upgrade at that point. relying on the meth to provide more fuel isnt the smartest but it does work. and people do do it a lot.

All I had was a home made CAI, EFan, EGR Mod, T/B mod, regular 3.42 rear, And Bigger than stock 265/70/15's. I also had no cooling fan as the were set up for fwd sport compacts that day, and they realized the fan was on the other side of the bay after my truck was strapped in.

Run 18 was w/ vehicle speed sensor on.
Run 19 was w/ Vehicle speed sensor off. (Damned torque managment )

Friction...Heat... and in an auto, I believe the lock-up torque converters actually unlock at WOT or above a certain speed... But I could be wrong.

those arent too bad of numbers that is more of what i expect to see out of a 4.3

no hard felings, stop by at nats and say hi

im sure TRTTURBO knows this im putting it out to help others reading
a pump would only help if your having a pressure drop at WOT. otherwise the only real fix is to add an FMU to increase the fuel pressure beyond what the stocker is set at

Umm Thank's I think. When I get my tranny and Diff back and upgraded I'll do alot more pulls. This time I'm gonna see if I can tune it. Some boost would be nice though. I think I will see if the turbo performance shop around here would be interested in rear mount turbos. Actually they already do. They are the home shop of a few Porche racing teams. I gotta get my cam out the next time the do a lil testing on the blvd.

Guys I'm really glad this post has become one of exchanging ideas and info instead of cutting each others throats.My project is 95% complete.Because of my distrust in fmu's,
I've invested in a meth/alky kit to make sure I can reach the estimated 300hp that the
Mach turbo kit is suppose to put out. As you guys know I also have a converted Edelbrock intake and a bigger turbo on the shelf. Sam and TJ will be my sources for the
basic TunerCat mods that will help me start tunning.I'm thinking of investing in a TurboLink
scantool to keep tabs on the performance. Keep the flame burnning. PEACE>Tony

the only problem with that is the injector flow rate and duty cycle is still going to be maxed. that is why FMU's are considered bandaids. the real fix is a higher flowing set of injectors with a adj FPR and new pump and some sort of tune either tunercats or ls1edit. either way you can achieve your goals but the FMU should just be a temporary fix and not permenant. i do know more than enough about turbo and fuel systems to know that using an FMU unless its adjustable can still cause a lean spot in tuning. and even with an adj FMU like cartech you cant completely get rid of lean or even flat spots in your fuel curve

So what are the best options for fueling in the 4.3 without going to the 2114 mani project?

So would I use the high impedance or low impedance kit, anyone use one of these systems yet?

Are they worth the money.

You can use high or low. Depends what extra injectors you get or want. It does not really matter.

BlackX has use this on his 2.2 with his wynjammer with great success. There are many others as well. Do a search on google you will find many others. Its a great product in my eyes.

Increasing injector pulsewidth is essentially the same thing as using an fmu. There is a limit to what the injector can achieve either way and using the Multec II injectors you're even more limited. The blazer in this thread is awfully close to that limit so achieving anymore hp will be practically impossible w/o upgrading the manifold/injectors. You could try an extra injector but Ive always been wary of them since the 4.3 manifold isnt really intended to flow atomized fuel.

The ONLY way to do this right is with a 2114 manifold converted to EFI using bigger injectors programmed with either LS1 edit or tunercat.

[PhatBoy]

Or you can use an extra injector controller that will control 6 additional injectors, and do some fab work to the stock intake so each injector sprays right into each cyls air path. Basically like doing the 2114 without the 2114, ya know.

not to be an ass but thats all good and well if you can find the room under the upper plennum

Do you have these pics posted on a site or can you post then here?
I have tried to contact gutless about his turbo setups but haven't gotten a reply
from him.
thanks.

with walbro fuel pump, and FMU you dont think you could hit 240whp?
