Re: Turbo 3800 blazer

update time

heres a few pics of the cage, and some weird stuff had to happen but I think I did it all right. also, I spend little time documenting what I did with pics so, sorry.

just getting started, prolly took 3 hours to get the hoop in there where we wanted it and get it attached. its moved over about an inch and a quarter to the drivers side to give me some more room. I mocked the seat in with some mounts to make sure it was gonna work and fee good. The big issue at first was that the hood didn't meet up with the frame and I had to use the 2x3 steel blocks to attach it. second big issue side crash braces ended in space about 6 inches from the floor with nothing under them frame wise. I solved that problem with some steel plate. its surprisingly solid...

Keep in mind this isn't done yet, the far box needs to be welded completly and the closer ones only halfway finished with plating. Also you can see the 2x3 boxes howling up the main hoop, and the bracing on the top to the frame to help give it strength.

difficult to see but I put a 3/8s plate coming off the bottom of the 2x3 box to give it additional strongness...

I also managed to take out the front shocks in preporation for the new ones. I have a friend of mine doing some machine work to my qa1 coilovers so that they fit better, he should be done soon. My fueling harness finally came in, as well as some other parts. After I get the cage finished this week I want to get the fueling and wiring in. I know I'll be out there wednesday and thursday after work, so hopefully I can get the welding done.

Re: Turbo 3800 blazer

I have most everything to get this up and running. I just need to get some time into it, I should have some updates wednesday or thursday. I need to get the cage finished, which should only take a few more hours of work, then I can hopefully get the fueling all ran, as well as the wiring all in. after the cage and the doghouse is done the fab work is mostly done.

I am hoping to have this along with me when I go to homecoming...

Re: Turbo 3800 blazer

Have you ever been out with the beautiful blonde bomb shell mother of your children then out the corner of your eye you see a potentially underage redhead girl smoking a cigarette in a wife beater with scaby knees and dirty flip flops? and for some reason you can't stop starring? It kinda like eating fillet mignon everyday but craving a hotdog. That's what this truck is, a slutty trailer trash redheaded hotdog..... I gotta have it

Re: Turbo 3800 blazer

that is an awesome quote, and possibly the nicest thing that has ever been said about anything I have worked on, thank you.

UPDATE

alright, I lost a few pics...but heres what I've been up to.

not much to see, hawk pads, new centrics. In the darkness behind them you can see the coilovers sitting in the shock towers.

decent pic of the coilovers, and an upclose of the wideband bung on the exhuast.

I started taking my cardboard cutouts I had for the doghouse and turning them into steel.

by the way, this pic should be a good all around idea of the quality of work being done. garbage can sawhorse, goofy jack/chair support. old aluminum drywall square as a guide for the plasma cutter. working being done on top of old pieces of Berber carpet which turns out never catch on fire, and even rarely melt.

I mocked the seat in to make sure it was gong to be comfortable when I sat in it and operated the throttle, which was also mocked in but I took it out before I took this pic. I was worried about the sharp corners but I dont think I;ll ever come into contact with them while I'm strapped in.

passenger side is a bit tight...

thought I would throw this in here...I got caught making racecar noises...

my gf started doing some sketches for the hood...

overall stance after the coilovers were actually installed and supporting the weight of the truck. I should note, the springs might be a little stiff....

Re: Turbo 3800 blazer

worked late last night. I got the dog house all fabbed in, and about 1/4 welded, and the seat bracket for the drivers seat built a little better. I cut the front feet and shortened them about a half an inch and I like the way it sits alot better, although its a bit crooked, leaning about 3/4 of an inch towards teh drivers door. I need to get my front propshaft lengthend to 31 and 5/16 inches...I also need some big self taping screws for the shifter, trying to bolt it in with the trans and t-case looks like it would be a struggle with the way I have the clearnace to the floor set...I think tonight if I get a chance to work on it I am going to get the transcooler in...

Re: Turbo 3800 blazer

well, I managed to get all of the gauges hooked up, and working (amazing, I know) ended up with more gauges than I initially planned for, and had to expand the 'pod' a bit

I also fixed the wideband, and mounted cig lighter for tuning charging puposes

pic of the wiring mess, its a bit better than it was but its still ugly and needs time. In this pic the TB was off so that I could clogg the fresh air intake part of the TB so that under boost the crank case stays neutral...

In other news it actually started tonight for the first time. It was an amazing thing, and I'm not sure how to describe the sound of it. Closest thing I could think of is like three 2-stroke motor cycles idling next to each other and somehow having a whistle and a cam loop between the three of them. its goofy...but it brought a smile to my face. so far the only issue that i have found is that my trans is leaking right where I didn't put a bolt into it. I left the bolt out because it interfered with my mount, but tomorrow I am going to have to take the mount out and re-engineer it to fit that bolt, shouldn't be a big issue. only other issues are lack of cooling fan, pass. seat, kick down cable. I hope to get the trans fixed tomorrow and get the seat mounted, and maybe even the fan, and then get the cable wednesday and get that figured out. nothing I can't do pretty quickly.

Re: Turbo 3800 blazer

had an issue where it wouldn't go into gear, and I wasn't getting any sort of line pressure. I figured it was something with the front pump not being engaged but when I tried to slide the TC into the trans farther it wouldn't budge. I tried to pull the trans out friday but I sliced my hand on an old front pump I was looking at for reference, and took a break. Today I managed to pull the trans and t-case out and get it apart with the help of a friend. after looking it over carefully we determined that 1. my front pump is badass and 2. it wasn't being engaged by the TC properly. With the trans out of the truck and vertical we were able to get it into the trans correctly, and re-installed the whole thing into the truck. I need to make some pretty big shims to get the distance off of the flex plate I am going to need, but I think I can get something together before the end of tomorrow. the pump now def. works, and even with the TC being turned by hand it is pumping fluid. I hope to be idling it around my yard tomorrow after work.

Re: Turbo 3800 blazer

Sounds wicked! Good job with the build.

Re: Turbo 3800 blazer

Thanks man, I'm going to do what I can to have it at homecoming, because its not looking good for the typhoon....

Re: Turbo 3800 blazer

Please tell me you are gonna have the redheaded hotdog at HC........We want to see it.

Re: Turbo 3800 blazer

I'm going to try my damndest. I am going to talk to my crank guy tomorrow about the typhoon but, the chances of having it back together in time are slim. That being said the rest of my free time will be devoted to making this run well enough to make it to the event, although it might only be pushing 14 psi...

In other news, it moved under its own power today...

Re: Turbo 3800 blazer

well, still having some problems, but nothing too bad

I guess I'll start with the bad, its having a big issue with starting. I believe its a few issues all forming into one, but when you try to start it it will turn over and then hit a wall, and freeze the starter, it will eventually start like this, but its frustrating. The wire leading to the starter is 2 gague, so its pretty thick, but after a few starting attempts its pretty hot. my theory is 1) the battary is a bit weak, and not able to provide an good voltage to the starter. 2) the cable is thick, but not thick enough concidering its almost 10 feet long. 3) when the voltage drops it dropps conciderably, like to 8 volts. this is triggering a low voltage event in the PCM and it reacts by increasing the pulsewidth of the injecter, to try an counter act the lowered injector supply voltage. This would be fine and danady in a normal car, but I have 1000cc injectors, and its just flooding the motor. I might be able to get rid of all of these issues with a new battary, but I am going to play with it a bit. Another note is when the pedal is floored it will go into a clear flood event and shut off the injectors. once this is done the motor turns over like a champ, until the pedal is reterned from WOT then it floods almost instantly.

the power steering pump bolts broke off. I am having a machining friend of mine repair the block while its still in the truck tomorrow.

also the headlights and blinkers do not work as of yet, and there is a small vaccum leak

the good

brake lights!

it is now insured and registered, I managed to cut my registration costs in half with a vanity plate.

it drove out of and back into the garage, and had decent brakes.
neighbors hated it.
fans work great.
once its running it runs like a champ

Re: Turbo 3800 blazer

starting issue fixed, replaced battery with cheap rebuilt battery, and replaced wires with 0 gauge welding wire.

Re: Turbo 3800 blazer

So far the only vid I have of it is the one of one of the first startups below, thanks for the compliments!

I hired a friend of mine to get the broken bolt off from inside the block , and he managed to do that for me for 30 bucks, which was a pretty good deal considering how ****ed it was. In the mean time I managed to install the pass. seat and harness, and he stuck around and helped with the oil change, wire 'tuck' and the other little things it took to get it to the point where we felt like it would be a good idea to actually drive the thing. At 1:30 in the morning we reached that point and packed up the extra c-16, tools, laptop, and fire-blankets for the first journey to meijers for E85. we got in, strapped in, and started it. It started the best it ever has. I back out of the garage and started heading down the driveway. It was taking a bit more rpm than I though it should to get there, but I figured it could have been the higher stall converter. I made it to the street and couldn't get it to accelerate, so we decided to turn around about about 150 feet. Keep in mind this thing is destroying all of what was 1:30 am silence. I stopped, backed into a driveway, and when I put it in gear it was gone, no more forward...so I shut it off with it half in the street....long story short, we pulled it back home with a truck, and there it is sitting. I was too afraid to start it again for fear of the people around me figuring out where it came from. I will say I believe that it is a result of low trans fluid.

it definitely drove down the street, and the belt defiantly didn't fall off, so there were some good things that happened still.

Re: Turbo 3800 blazer

Why is it so loud? Might be an idea to quickly fab up a muffler setup if you're as anxious as you seem about the noise. I hope you haven't fried the trans.

hes got the "mrsyclone" exhaust. sounds great. but damn its gonna be loud to drive.

Re: Turbo 3800 blazer

its definitly not silent...

trans issue still lingers. I am going to contruct a trans pressure gauge of power washer parts and check my line pressures out. I am hoping I can get the guy who helped build the trans over there tonight. Other than that its ready for a drive.

I didn't think so many people were watching this thread, at homecoming I had at least 20 people ask me about it. I noticed I wasn't introduced as the autocross typhoon guy of the group but rather as the hotdog girlfriend blazer truck guy.
