Re: What I have been up to -- teaser
Yeah, works on a '730 too. I had to re-read my own FAQ thread from 2003. The older I get, the more I forget.

Re: What I have been up to -- teaser
Idk if its the injectors or the hardware that controls them but everyone i know that runs new generation big injectors high z dont seem to have any problem getting stable low pulsewidth operation. You should be fine in something like fuel inj connection stuff in the 1000-1300 cc range or FID1000's. Idk how much power you need. 1300's were good to 1400 flywheel on race gas. The 1000cc should be good to 1000-1100 i would think

I think the newer injectors you are using have better solenoids that respond faster. That would be my guess.
My blower could make 1,000 hp with my heads + cam, but my 2bolt main block will probably explode. I don't plan on pushing it more than 600hp.. Even that might be dumb on my part, but if it explodes I can build something else. Shoulda used a SHP block.
Any updates on your build?

Trying to buy once where possible.
ATI has a 32-1? damper setup that Nelson Racing runs on his stuff.

Re: What I have been up to -- teaser
Yeah i had tc72's basically but prior to that i had masterpower 70's and had both .68 and .96 housings. Then bought a on 3 t70 for my 305 car and used the .96 then .68
Sold everything but the .68's
I tell ya what, the s369 billet turbo for 1000$ is likely best thing out for a high hp twin v8. Hell theres gtr's making 1700 whp with them. Flow 100-105 lbs min each

Re: What I have been up to -- teaser
I looked at those...I'd need an LSX block for them. I don't need the temptation.
Still debating on filled block and pyramid rings for phase 2.
Regular TC72 is about the limit of a stock block and smaller and lighter than S300 series.
-and $750ish each.
I need to start saving for the kids college fund next year so a big parts build can't be done. $8K easy in parts for short block.

Re: What I have been up to -- teaser
I got my holley from moore racecraft. I haven't got into this yet with the 66lbs inj. But he basically told me if I wanted I could put 120s on it and it would idle like stock. High impedance injectors have a faster response due to the the higher current...."kicking" the needle off the seat. They're also better in boosted applications where fuel pressure is higher and needs the added help against the fuel pressure.
Sequential injection and more R&D time by the OEM's is why they idle better with big Hi Z injectors now.

Re: What I have been up to -- teaser
yes, low impedence will have more current flow and in turn a stronger, faster acting motor to control the pintle. in theory, they should be able to idle better than a same sized high impedence injector.
-but your pcm must be able to handle the current, and injectors in general are better today than they were 30 years ago.... so todays large high impedence injectors work pretty dang good.

Re: What I have been up to -- teaser
Its nice but doesnt have enough features to monitor the things i want to monitor with this build. I want to watch egt, multiple widebands, fuel pressure and have built in timing/boost functions. Ideally traction control in the long run. I'd like to limit the number of gauges and add ons. I like how holley has some timing retard functions and i dig the layout. Datalogging built in.
I'm sure ms3 pro does as well. Been awhile since i looked at its feature list.
I had some issues getting my sbc to start consistantly with the 24x efi connection setup so i wish to avoid that. But that may have been partially to blame on a loose reluctor ring

Still up in the air on dual injector banks. Current manifold doesnt seem to have room for a second row of injectors unless its under the elbow. If i sell and refab an intake with 16 inj, a efi system to handle that will be nice
I've been thinking similar things with my converted single plane (same packaging issues further up the runners). I don't have the idle control that I would like. In my case it's not about your killer power production, and 99% of people would be happy with the idle I have, but instead since I have crazy ideas of tuning this thing for efficiency I just don't have the tuning granularity down low that I want, and I'm not sure that even if I went to sequential I would get it.
Because of packaging I'm thinking of making an adapter plate that mounts in between my elbow and my intake and mounting 4-8 large injectors in that and then something more normal down in the bungs at the end of the runners. 4 or 6 injectors would be easy, 8 would probably mean I'd need them on 3 or 4 sides of the spacer and would make plumbing complicated.
What are you using for an injector strategy? What is the dead time on the FIC injectors?
My Siemens 60's have an open time of 1.14 msec at 14 volts, and a close time of .85 msec. (http://www.siemensdeka.com/product/6...fi114961-60mm/)
Obviously this made idle a pita to tune when I was running 1 squirt, all 8 injectors, per revolution as my required fuel put my pulsewidths around 1.9-2.2 msec.

Re: What I have been up to -- teaser
Ms3 pro is or seems to be a separate system to the other ms stuff. Theres quite a few big power cars using it now
I do like the simplicity of holley hp but may need add ons to do logging of various parameters. Its alot to think about, the dominator would be great but it is expensive. At this level everything is.
No idea on the trans yet. Th400 but undecided whos gonna build it

Re: What I have been up to -- teaser
There has been more than one situation where I didn't get an answer to a question, or the answer didn't seem to be consistent with my experience so I had to dive into the source code to actually see how the function worked. Tunerstudio is getting better about showing you the logical conditions, but still.
A lot of the guys making big HP on MS3/MS3pro are also engineers and do this as a hobby.
One of the biggest problems with the whole MS thing is starter calibrations. People get very frustrated because there is an overwhelming number of things you need to configure.
Good luck with the build.

Re: What I have been up to -- teaser
From what i seen, it doesnt appear to be anything like how you describe. Its a box thats 100% done. Nothing to set up.
Software wise i do not know but pretty sure its also improved from previous megasquirts.
I have been talking to guys who use it and it doesnt seem to bad. But i need to continue looking into it.
Good thing is i can figure out justabout anything given enough time. Lol

Re: What I have been up to -- teaser
You will need to configure our ignition trigger, ve table, AFR target table, cold enrichment, spark map, idle settings (and no, i don't just mean target idle speed), decide which AE algorithm to use (they are very complex), air temperature related adjustments, etc.
It's not a huge deal, but it isn't a Holley that asks you 5 questions and then starts.
It has a lot of functionality that you are going to need, like staged injection, table switching, etc.

Re: What I have been up to -- teaser
Setting up parameters shouldnt be to bad, it needs to be done with any system as i plan to use ls1 style smart coils and a 60-2 crank trigger. It should light it off. We shall see.
Thats a long way off. Hope to get motor plates in soon and start hotside planning. May order 1 turbo and plan the pipe route

Re: What I have been up to -- teaser
I have no idea but its not built for that kinda abuse. I wouldnt mind doing a half mile or mile event... but i dont have the gearing for that really. I would need a gear vendors od unit. I am gearing the car for 200 mph capability at max rpm

Re: What I have been up to -- teaser
True enough. I hadn't factored the gearing in: Vis-à-vis, drag racing vs land speed or standing mile for that matter. Come to think of it, does anyone here participate in that kind of sport? Plenty of road racers, Auto-X and drag racing but I can't recall seeing an open road or mile event participant. I certainly am contemplating that.
That said, it's plain to see now that you're targeting a 200 MPH trap speed!
And reviewing the Drag Week class winners, it seems that a GV isn't a bad idea.

Re: What I have been up to -- teaser
Its gonna take alot to go 200 traps but would be cool. I think i'll end up closer to 190 cuz the car is so heavy.
There was a guy here that did texas roll race events with a turbo sbf powered firebird. Nasty car, also near 2000 hp capable

Re: What I have been up to -- teaser
Thats gonna be a while before that gets done. No funds for this. I have two buddies that do good cage work and likely one of them will get it when time comes. Then again i might only do a 10-12 pt for 8.50 legal cuz i am not crazy excited about the funny car cage and X brace door bars. Very difficult to get in and out and also to see anything. Bars around the head kinda make me nervous too

Re: What I have been up to -- teaser
just dont want to start a thread and leave it sit without updates for long periods of time... i’ll post the build when its closer to completion. First step is running na all motor and work the holley tune in. When i get there i’ll make a build thread but not sure here yet since its not boosted yet.
motors been in since spring and fabbed headers semi mocked up months ago and only now gotten around to finish welding. Still gotta do collectors
