    Nice and cold tonight quick squirt up road to grab dinner. Way more induction noise than before maybe the old maf was a restriction. Logged on weekend upt to 4000rpm air/fuel is safe could do with a bit more under boost to get it to magic 12:1 fuel ratio recommended on these things it's only mid 12.5:1 so I won't stress for now. I need to get the Blow Off valve on I'm paronoid of blowing another turbo. Overall big MAF appears to have fixed a few things it appears it wasn't as rich as I though once warm doesn't stink like first start so I could pull some fuel out on start up. Feels faster but I've been driving a diesel Holden Colorado all week could be placebo. Going to pull some timing and tidy up fuel a bit more..... Maybe crank it up to 15psi see what falls out.

    Current engine is starting to get a bit of a rattle at idle and on logs it's starting to lose sync on Crank angle sensor occasionally. That end float I've ignored for 5 years is starting to get worse. I've got a supercharged block with 2 scratched bores, I think I might try honing them see if they "Buff Out" and replace the 2 pistons if damaged. That'll get it a strong bottom end for a around a 1k. If not rebore and new standard pistons is probably reasonable too.

    Chucked in new airflow meter today fired up fairly easy running quite rich so I'll need to adjust fuel to suit. Just fudged wiring together till I'm happy to wire in permanently soldered ends and jammed in original plug. Its linear on wide band though so I could be able to get away with fudging some injector tables to bring it back in spec.

    Pm me what ya after will have a think

    I have been eying up some massive BMW brakes for quite a while but they would need some machining im just not up for at moment. I've had this thing up to 220kph now and there its still pulling hard at that when you see sparks as your slowing down it makes you nervous, Keen to hear how you go with the vf upgrade once your done.
  6. Muncie
    Will do, everything else you suggested worked well. It hooks up really well now front and rear with wider track tyres and shocks. Keen to go roll racing when that's on next. I've dropped down to a 30 profile tyre in rear I did a 14.5@100mph on a 40 profile so that should be a healthy bump in gearing to get it leaving better and coming on boost earlier down track where it was a slug previously.

    No safety features what so ever just pure mechanical inertia and petrol fumes. I think i might fab up a chute over blade in case i ever go over handlebars as i certainly came close heaps first time out.

    Cleaned up the height adjustment sharpened blades then adjusted clutch and its a certified ripper! Did our lawn in 15 minutes normally takes about an hour, I was absolutely dripping in sweat by end of it! It sprints i slowed it down a bit but it still beats the shit out of you. But shit half decent job for first attempt it ripped down the high spots effortlessly and kaikuyu grass didn't have a hope in hell of clogging up this thing.

    They bite pretty well aren't the entry level ones still cheaper than other things out there, good starting point incase to try out this width. But I'm open to sending them up in smoke at drags! They leave huge 11's and look fat which is cool.
  10. Muncie
    Took the long way to get the width wheels i wanted ended up with 245 35 19 Pirellis up front on 9" rims and some Laufenn 275 30 19 on the rear 10"s plenty of meat, offset must be favourable doesn't rub and steers better than the Holden wheels i was running. I had my mind set on a 255 for front but these came up for 100 bucks..... what's 10mm anyway. Not the dream wheels but they aren't horrible and keep the factory.....ish vibe i like about this thing. Springs should be next now bum down front up slightly would be mint.

    Ooooh old shit! Gotta catch em all

    My silicone reducers showed up so can assemble the next part of the inlet puzzle, Camaro/Saab MAF turned out to be some guesswork as it falls between been a 3.5" and 4.0" so took a gamble ordered 3.0-3.5 reducers and hoped they would be able to stretch over. As you can see success, bit of slippery stuff some grunting I now have a slip on upgrade that should give me good resolution to about 20psi. You can use a LS7 card MAF but these are apparently tricky to dial in without a dyno and dont look as cool. When will I fit this? Not sure. The new operating system i flashed in has some quirks i dont understand at moment so need to work those out before adding this in to mix.
  14. Muncie
    I might try get some 15s if budget allows or something at right price does. Could jam some 175's on my steels for front as an absolute bargain option. Think my 275 30 19s will get power down pretty well this time if I just run as I brung i ran a 14.5 on a 245 40 19 with all the shit in the boot first run last time on 5 psi next run was the 14.1 and cracked the exhaust manifold. I'll keep eyes out for some oldschool.co.nz approved small rims though.
  15. Muncie
    Few minutes to spare let's see if i can get these other 9" wide rims on front..... rumour has it spacers are needed quick test fit says possibly not, their close but I've run wheels closer. That's a win these aren't my dream wheels but they do meet my criteria of been the widest possible width the guards can accommodate without drastic surgery i could even run a small spacer on front and get the fitment dead perfect with a 255 35 19. Think ill just give them a clean up and rattle can throw on some tyres and run them. Should get the front looking as pumped as rear with a fat tyre up front. Oh and the silicone reducers to fit the new airflow meter are almost here so can get on to mapping it to 20psi! And heaving the rods out the block..

    I'm also aware i need to sort my suspension out, the back is sorted out for shocks but needs to come down 50mm, i was naughty and just cut the fronts for drag day so i was always going to need new springs so i think that's where my energy (and Money) needs to be at moment, The engine is fine as is and should be making about 300-320hp and i can rig up the new MAF retaining the old wiring so i can go between the stock one and the LS2 MAF using my 2 PCM's with different calibrations so i can tune as i get time but roll back to what i know works. Its annoying i need to Cert this but is what is. Maybe 2026 i'll book it in once i build a fresh engine.

    Did Some things today all software stuff uploaded a patched firmware that upped Max Cylinder airflow from 700mg/ second to 1650mg/ second Pulled 10% fuel out then took for a test drive and it now knows what its doing with timing and fuel at the top end i'm seeing up to 953mg/sec at 5500rpm if i change my shift points it will rev to 6400rpm now. Previously it would go flat after 700mg/s but still pull now it just goes and has mapping to do it. goes with one caveat i'm out of Range that my MAF can now measure peaking at just over 10800hz. i've got a LS2 MAF that is both bigger and able to output up to 14000hz which should see me hit my 6400rpm @20psi goals which should make around 450-500hp according to a few dyno operators in oz that have seen a resurgence of turbo Ecotecs now LS stuff has become expensive again. Fitting it will mean starting all over again and setting up the tune to work with the different output of the new MAF. Annoying that this Patch in the software probably would of got me a 13 second pass at drag day..... oh well I'm still Beta Testing a Spark cut Rev limit for Pcmhacking.net thats on hold for the moment as it needs some people much smarter than i am to tweak the code to get it operating quicker so you dont lose 900rpm per cut event.

    Feel this fits here

    To bridge what your doing here and what i did i built basically this thing minus a cage 20 years ago, mechanical injection with open throttle bodies but destroked from 2500cc to 2000cc best i got was 9200rpm (old monster tach probably inaccurate) and it sounded amazing flying by. Exhaust wise i found keeping the exhaust short made it sound best. I had a super44 3" flowmaster under the drivers seat and it sounded glorious with a full exhaust and 3 mufflers it was as loud sounded completely different but about the same volume with 3 mufflers. What's your firing order? Above is 153624 Considered going side exit?

    Sounds mint once the induction starts doorting. I love the sound of 6 though so heavily biased and loving this project.

    I'm sure Roman will fit his own gps guidance system that couriers it straight back to the workshop after been thrown into low earth orbit.

    He's bought new bolts already he'll spring for a good tap and try that first he was pretty gutted. Hopefully can avoid new hubs as that is 300% more fucking around than needed. It's getting towed back from WOF shop to my place to look at.
  23. Muncie
    Opinions wanted here, back story my neighbour who's a top chap but buys the worst cars...... has bought himself a lovely Mercedes just stuck it in for a wof needed a tyre upon taking wheel of found the wheel bolts in this state. He's been quoted $3.5-5k to replace all the hubs yup they're all like this. My guess someone bolted.5x114.4 wheels on a 5x112 car by just ugga dugga the shit out of them till tight What can he do other than hubs? That'll pass a wof.
  24. Muncie
    Have I got a solution for you! Tunerpro a Delco PCM and that would actually be a piece of cake.

    Turbo tech

    Muncie replied to xsspeed's topic in Tech Talk

    I have a second one that needs a 300 dollar rebuild...... im tempted to go twin turbo and make 1300hp but im not sure a Stock block engine would not disassemble itself. Good reliable and cheap is a possibility now, good oil and filtration to turbo (and a regulator) a good drain to sump without many bends is key to the reliability. And Water cooling to keep the bearings alive.
