Looks good. And p.s. i just got home with my 305 tpi motor.

 

?? 305 tpi motor? for what?

 

I might just stay a little more local with the dyno, as Ida Automotive is right next door in Morganville which is on the way to Old Bridge Raceway Park (e-town). Those guys wrote the book on TPI, in fact they have a very well known article called TPI-101. I'd like to go over there and not only use their equipment, but show them what a little ole 305-TPI can "really" do...

Hmm, I'm now suddenly in a "Disturbed" kind of mood...

 

Just got word back from RBob, and it's a go. My plan was to run two communication cables, one leading to the plug-n-play area in the pictures above to be tuned by the laptop, and other leading to a Windows tablet that I plan on mounting into the dashboard, which will have key on turn on, and will do everything from displaying the WUD constantly (which doesn't need a wireless router) because it will be hooked up via USB, as well as XM satellite radio which of course is its' own wireless router, as well as everything a PC will do when I am essentially near a wireless router either at home, or somewhere else...

 

May try one of these experiments next year or two hehe

 

Tuning Update

Firstly, RBob, you have the patience of a saint lol. Okay, the first datalog I wasn't too thrilled about, mainly because I was having an issue setting idle RPM at 1000 in preperation for some VE learning, and it remained steady at 800-RPM no matter what I did, in turn causing the engine wanting to stall because of the size of the cam. I had the stop screw on the throttle body as far out as she could go, and it still remained at 800-RPM, which made no damn sense to me, at first. Throughout this ordeal, BLM's were at 108, and the INT was at 115, O2's were close to 900mv... no matter what I tweaked. Completely overlooking the "history" of the car, RBob pointed out something from one of the datalogs that I sent him, that being the trans appeared to be set in gear...

As soon as he said that, I immediately remembered that the GTA originally came from the factory with a 5-speed tranny, and that for the longest time whenever I had a scanner plugged into the ALDL port the scanner would always read that the vehicle was in gear. After looking at the harness I am convinced the Park/Neutral switch isn't grounded, but I'll get to that issue another time. Long story short, I went back into TunerPro RT, and targeted the IAC idle values in "Drive", not in Park, and set the Coolant to RPM values, and now the engine is happy at 1000-RPM. BLM's are steady at 127, and the INT is right at 128. O2's are still a little high, but the narrowband is still in there, so considering I don't smell any fuel in the exhaust anymore I will take the O2 sensor's data like a grain of salt. Since this, I did three VE learns, and let me tell you RBob made it so damn easy to flash a new bin in, and I say this because as soon as your VE learn is done, it is already waiting for you in the flash screen waiting to be applied. The engine is smoothing really nice, dyno time coming soon...

 

think you'll ever sell this car when you're done with it? just wondering. if you're doing all this because you really love the project, or more or less just to do it to show everyone it can be done

 

This car has seen some crazy times with me, would be very hard to let it go...

I'm honestly doing this for quite a few reasons to tell you the truth, and most of those reasons will be more than obvious after the goal has been reached...

 

Tuning Update Two...

Why my Spark Reference was different from my original setting I have no idea, chalk it up to the 100 degree temps outside in the sun and me not thinking straight because of it lol. I was on my sixth VE learn, and the EBL-P4 was still correcting for me, but the engine reached a very hot temperature and started surging a little. Could be one of two things, the start of vapor lock perhaps, or the engine just likes to run richer at idle. I'll know for sure once I get the engine cold again then restarted. Also need to work on some open loop tables, as when the engine shuts down and is restarted when hot, it has trouble holding an idle until the timer for closed loop is reached. I need to stop playing with closed loop and BLM soon and get that freaking wideband in there...

 

something to prove? also jw do you have any kind of ...... i guess youd call it sponsorship or support for this build or are you just one man alone in a garage with too many tools and too little time

 

What's with all the questions lol...?

I feel like I'm being interviewed by Rolling Stone magazine lol; "Street Lethal, one man, on a mission, to take his 305 places that no other man has gone before" (insert James Earl Jones' voice)....

To answer your question though, I live two minutes from Raceway Park, this whole area that I live in builds cars, you can't drive to the store without someone wanting to run you at every light. It's in our blood here, and being I've been a member on this website what, for ten years now? Figured I'd give back to the community in which got me started with F-Body's...

 

Ohh who you kidding. stomping some asses and saying its "ONLY a 305 " IS GONNA BE NICE.

This build makes me always thin of prestons turbo iroc back in the day. another 305 running 9's. Just a different bore / stroke 305

if I had to start all over again it would be a budget build stock 92Z with boost.

 

now that would be a great magazine article "street lethal, one man, on a mission, to take his 305 places that no other man has gone before" "born into a world where racing is the norm and everyone goes full throttle" haha

 

...

... or Fast and Furious 7, O'Connor's Godzilla meets its' match.

 

vin street lethal deisel......hmm imma go call hollywood real quick

 

Gonna pick up with the tuning as soon as time allows, as right now its way to early to be out there with the engine idling because, well, its freaking loud lol. I took it for one test drive before I parked it for the night last night, and Acceleration Enrichment is definitely on the agenda today. That and a few more VE learns with an actual load behind the engine both at low RPM throughout high RPM. Still need to tweak Idle Speed vs CTS for when I restart a warmed up engine because she will idle too low until Closed Loop kicks in (which is timed after restart), but for some reason I couldn't find Idle Speed vs CTS in Tuner Pro. Either my eyes were freaking shot from last night, or it simply isn't there...

More coming up soon...

 

Down near the end of the IAC tables:

IAC - Idle Speed: Drive
IAC - Idle Speed: Park/Neut

What causes the issue on a hot restart is that the MAT gets heat soaked. Which throws the open loop fueling off. Once in closed loop the fuel trims take care of it.

Best thing to do is to get a real IAT (bird cage style), and mount it where it isn't as affected by engine heat. But still reports the incoming air temperature. With a boosted set up this needs to be after the SC, turbo, or whatever is being used for boost.

RBob.

 

How about "*****" he had a true 305 with a blower, then a turbo. He had some pretty good #'s too from what I remember. I think he still is a Moderator here. Ill try to find some info on his car.

 

Some info on "*****"s car.

Preston Smith's IROC.

Anybody recognize this car lol ?
https://www.thirdgen.org/forums/powe...ck-w-dyno.html

Thats with the original 305. He ended up doing over 700RWHP before selling it to the present owner that we all follow on here now.

 

Yeah i recall this car but until i see trap speeds i am skeptical of the power produced

 

Don't know too much about *****'s project, but I will gladly call to both Z-Daddy and Preston Smith's 305 Supercharged builds, and I am not saying that in a disrespectful way, but in a "put up or shut up" way. One thing about my build here is your going to visually see what it makes and runs, you will NEVER here me say "my 305 made 1000 horsepower" then spend post after post explaining how it did it, while offering no proof whatsoever to back up the claim. Somebody asked me why I am doing this, and THAT is why I am doing this, I will prove that it can be done. After all, this is the Internet, the place where everybody has 1500 horsepower simply because their signature says so...

 

Ohh ya I remember all of em. ******* car was always amazing.

 

I can tell you Prestons was / is real deal. Have videos of it running the #'s Have BSed with him many of times back in the day. is it a stock 305 NO.Its a 4.025" x 3" Engine. puffing on 25lbs of boost

 

Brought the laptop over to my Grand National buddy Paul's house earlier today, wanted to show him some datalog files. The engine idles with 10" of vacuum at 950/1000-RPM, and he didn't believe me at first. This is a monster cam for the 305, you guys are in for a treat when I hit the damn track. I only hope it holds together for at least one clean run, because if it doesn't, I am still uploading the video showing the carnage if need be. Will hold nothing back, even if something happens on the dyno, you will all see it. But anyways, I was showing him the datalogging, VE Learning, Flash section, screens, etc of the EBL-P4, and he was like, "my XFI-FAST does the same thing", and I responded, "yeah, but your XFI also costs fifteen hundred dollars more than mine" lol...

 

Oh no, I believe his turbo 305 (with the 4" bore) ran the numbers, especially at 25-lbs of boost pressure, I won't call BS on that because then I would be contradicting myself. But his factory 305, the one from the magazine, huffing on the Vortech supercharger is an entirely different animal, especially at 16-psi w/no boost control, small injectors, and the weight of the vehicle. Maybe mid to high elevens, but not tens...

 

**** i'd be happy with that, any idea what kinda power/times i'd run if i turbo'd my poorly running 2 stroke l69?

 

you shouldn't be, lets just say I've been banned here but as a pre-year-2000 member I can tell you anything Willie done was legit.

 

Justin was referring to Z-Daddy's car, not *****'s car...

 

So is this a race to see which turbo 305 hits the 9s first?

 

Nah, nine seconds is a goal I honestly gave myself because of the guys that I hang out with, nothing too special by today's standards. Let's make our own 305 race a little more interesting, lets do the four digit race, let's say the first one to a 1000-RWHP wins (cast, forged, whatever it takes)...

Edit: By the way, congrats on the EBL-P4...

 

Sweet. I love to see the competition. If I had some ppl around my area that weren't so fixed on ditching efi for carbs and think turbos are a joke then I would have some competition for a build. There's a recent friend that ditched his efi on his 383 firebird for a carb because it wasn't fast out of the gate(wasn't tuned good at all. 13.5 afrs WOT with 12:1 compression) I kept telling him to add in more fuel, switch over to a 7730 at least instead of the 165 as the MAF tuning was hurting him, play with the timing some.... and so on but you know how that can go when you try to give some advice. I'm not sure if it was because i'm a V6 guy or what. I was truly amazed he didn't kill it. I just shook my head as that car was capable of some fast times if tuned right.

Im ready to see some vids of the car and what its got.

 

Vids are definitely coming. Was going to throw up some .dat files that I converted to .mpeg files and upload them on youtube so people can see how the WUD works and the various screens, as well as VE learning, other features and my own personal datalogs. Still going to do that, but I know you guys just wanna get to the meat and potatoes, and want to see the thing take off from a dig and a roll lol. Those Grand National guys have their tuning down to a science boy, lemme tell ya. Just goes to show you never stop learning, cuz I literally got schooled last night by one of the best around. Even with 10" of vacuum, the damn idle is tame. Wicked... but tame.

 

This is gonna be a fun summer. I should update my dam build thread.

 

Put that cookie down and get back to that build thread....!!!!!

 

Lots of tuning to do still, but the last datalog I sent RBob is as follows...;

Idle...

Injector Duty Cycle - 6%
Injector Puilse Width (synch) - 3.8%
MAP kPa - 65
IAC Steps - 95
Spark Advance - 24 degrees
INT - 131
BLM - 115
O2's are sporadic because of the Narrow Band...

Gotta get the IAC steps down some more, as well as my MAT temps because they are way too high, although it has been averaging 92 degrees here the last few days. Might have to relocate it soon as well...

 

Funny thing is for same money spent on that 3" crank he could have gone 3.75" and ran same numbers on 10 psi less boost lol. That was an interesting purpose built motor just to be different. Makes no sense to do that 3" crank unless class limited or trying to be different.

 

hey your in ohio, when i finish my 5.3 swap we can race if ya want, be my first time driving at the track, you pick the track i honestly don't know of any near me except aldermans

 

I agree. Back when I talked to him it was a class / stock displacement thing . Its a bowtie block stuff a dang 4inch crank in it. and let it eat all the boost you can dish at it. with some more cubes.

 

where did you get the headers for the turbo, would it be best to install a turbo on the stock 305 or a 350hp crate gm350?

 

if you are new to tuning stick with n/a until youve learned to tune. the gm350 engine has cast pistons and will get destroyed at first detonation. im sure the 305s are cast as well?

 

as noted, the 350 is out of the car, has been sitting in the wheather for 2 ys that i know of, im sure i will have to rebuild it to some extent, dropping forged pstons in will be nothing, was wanting to stroke it to 383 anyhow, and tuning to me isnt that hard, may be young but i have been around the block a few times more than i want to admit

 

Frank, cubic inch displacement is irrelevant. The only real difference is that it will take more psi for a smaller engine to make the power that a larger one can make at a lower psi. But when you look at it from a cooling perspective, meaning if the air temps are where they should be in both cases, then it is completely irrelevant how much psi you run, believe me. Example, if a 350 at 10 psi can make the same power that a 305 can make at 16 psi, the rotating assembly in the block doesn't care, as it is still being subjected to the same amount of horsepower, and if air temps in both situations are the same, then it just doesn't matter how you obtain the amount of air necessary to meet your goals. As for tuning, there is always something to learn, so always keep at it. That being said, if you already have the 350, then just go with it...

 

would it be best, while im at it, to replace the rotating the assembly with a 383 and have my dream motor with 8-10 psi boost?

 

There are too many variables to say what you should or shouldn't do, as 8-10 psi is very different when it comes to which turbo we're talking about here. Some flow good at that boost pressure, and some flow insanely monstrous. Cast assemblies are good and will last at up to 500-FWHP, any more than that and you are really pushing the issue. If your 350/383 shows that the bearings are in good shape, then you will not need a new rotating assembly, just throw some synthetic in it, throw on some steel main caps for added insurance if your worried, and just enjoy your 8-10 psi ride. Remember though, bigger cam, better heads, and better intake means more air at the same boost pressure, so take it easy with those choices if you decide to keep the stock cast setup...

 

Small update, have been chasing a Code 43 issue which was finally sorted out today, RBob caught a typo I made in TunerPro which was the culprit. Was running very rich throughout the idle tuning, and the plugs are more than likely fouled because of it, as I am getting some light to moderate shaking upon throttle. Gonna pull the plugs right now and have a looksie. Anyways, the GTA is now re-registered as well as re-insured as of an hour ago, so I can finally get to tuning this thing on the highway soon...

 

Wow those freaking yellow spark plug wires that I was using in the interim before the turbo is installed were arcing quite a bit, was telling TwinTurboRoc about it last night. He talked me out of the MSD wires, so seventy bucks later I wound up with Accel's. Didn't want to wait for them to be shipped so I just took a ride over to Advanced Auto and grabbed them a few minutes ago...

 

EBL-P4 idle tuning is done. Even with 10" of vacuum which is confirmed in the video, she idles like a kitten at 900-RPM. Engine revs smooth, and during the second blip of the throttle it reached 6000-RPM no problem, which is where I plan on shifting. Also shows VE learn with the EBL-P4, as well as the main WUD screen and diagnostic screen. There is also a spark advance table screen, but I will embellish on that another time. Quality of the video sucks, but I wanted to update this thread to show where I am at the moment. Still planning on getting her on the highway soom and dialing in the VE in every single cell available, then I will concentrate of acceleration enrichment and spark advance. Light on the dash is airbag deploy. Enjoy...

 

Your video sucks. Now im gonna go look at it.

 

I have a good video camera waiting to get hooked up, but until that happens I am relegated to my crumby phone camera lol. You gotta hear it in person, sounds unreal...
