How long till it grenades? ( It never did! Go figure.) Grenade part 2 to come.

[MONTEGOD7SS]

I would be curious to see if the crank is twisted at all, or if the rods show any problems.  Bottom 9s with junk parts is awesome!

Im betting its all ok. The main bearings showed slight edge wear indicating quite a bit of crank flex which is crazy considering how rigid cast cranks are. The bearing clearance used to be at .003 mains till i replaced the lower shells with more GOOD USED ones. The rod bearing clearance, uhhhhh. . . . . . . i dont have a clue. LOL
The lower shells tightened it up to .0025 and after that, i realized it was the wrong thing to do as it started showing copper on the outsides. I firmly believe a 1000 hp motor needs huge .003 clearances to let natural crank deflection have room to wiggle. The ring gap was .090 of all things and id guess bore taper at .005 at the most (pretty good). It has a sleeve in #1 hole and is bored .040. The rod bearings, rods and pistons looked absolutely ordinary and if it was sent in as a core motor somewhere, any teardown guy wouldnt have seen a thing telling what its been thru!

Its amazing to me that i DID detonate the balls out of it HARD one time on pump gas and then again at full boost and NOS with only half a load of race fuel and the pistons lived. It actually rattled thru most of 3rd gear before i realized what i was hearing and lifted. That was its last run ever as it filled the overflow to the top and smoked the gasket on #7 cylinder.

After that, it did some low boost street driving for 2 more months without losing much more water at the lower power level till i yanked it for good. The way that sucker felt with 25 lbs boost and a 75 shot of spray was amazing. Listening to it wail with the front end raised farther up than usual all the way down the track made me think it HAD TO expire before the end of the 1/4 mile! But, at the end of the run, there i find myself stopped at the ET shack idling smooth as glass in perfect condition getting my timeslip as usual.

I knew it was the best run ever as i wasnt even watching the tach thru the lights and noticed the RPM's sounded like they were WAAAAY up there across the finish. Glancing at the tach showed 6000 RPM, the highest it ever revved and about shit myself when the slip read 9.37 and just cracking 150.50 mph! I know the car is faster with the new motor but the fun is gone wondering if its gonna fireball on the next pass when the GRENADE was under the hood.

Its amazing to me that a stock 2 bolt block with every factory bolt still holding it together can survive that much power with ZERO damage seen anywhere upon teardown. If i remember right, 738 whp was the best number it made. Thats insane! Every hole blew 30 to 50% leakdown the one time i had the nerve to check it too. The saga must live on! If i can weasel it back from Hillbilly, i swear ill plunk it back in this winter guys!

[flyinhillbilly]

do it!!! i've been dicking around with these bikes and kind of got out of playing with cars, the grenade needs to be punished some more.

[tt350chevelle]

I can't wait! The grenade is coming back!!!! Your grenade thread was one of the main reasons I started to visit The Turbo Forums, lots of fun and straight out testing, an absolute blast to read and be apart of, long live the grenade!

I hope you continue with the testing and find where the actual limits are...

Hey buddy! Good to see you posting here again. Musta gots a new computer eh? Ive been meaning to call you since i blew off a few of your calls. Everytime you have called me, ive been right in the middle of something when i couldnt talk ( and i know we can talk about chicks, bikes and blowing shit up for hours ) and like a dumbass, forget to call back.
Anyhoo, i aint no indian giver and its still your motor. Ill buy it back from ya! Or trade it for beer. Lots and lots of frosty, brewed goodness. . . . . . . . . . . . . Man. Now im really thirsty all of a sudden.

Im with you on this all the way! I re-read the first 14 pages of this thread last night and was amazed it was started in 2006! All the fun i used to have kind of slapped me out of a coma and i thought  "maybe we should do this again". It was the funnest thing i ever did and (such as life is ) you get bogged down in work, bills and bullshit that takes away all the fun. Well screw that! Its still Hillbillys motor and maybe he just needs to get it. . . . . . in smaller pieces.
I feel bad it never got shipped to him as i appreciate the hell out of the Car Craft article that came of his actions. Soooo, with his input and blessing, lets start doing a re-buildup this fall and inspect the whole thing for cracks, wear, lots of pictures ( possible some nude photos too ), new rings, bearings and ACTUALLY degree the cam for once. Cant think of what to do to up the power level past where it was though. More NOS is an option and i suppose a few more degrees of timing would kick it up another 40 or 50 ponies combined.
Or, do we rebuild it and give it to CAR Craft for a engine dyno session with one of the wrench rat turbo systems on it? Car craft already has a Wrench Rat system donated by Steve berg (wrench rat owner) and i bet they would die laughing at the chance to pummel the world famous GRENADE! Shit, that might be a great business opportunity for Steve to promote his kits, get real live power figures on the poor thing, prove none of this thread is fake ( for any non believers ) and blow the shit out of it with style. Run it just like it was only fresh rings and bearings.
Input please! From everybody. I dont think of it as my motor anymore. Its a testbed for all of us. Hell, the cam and intake were donated thru the years to further the cause so tell me what to do guys.

[droopy]

i think thats a pretty cool idea about letting car craft beat on it.....

[Ssmonte408]

I'd rather see it blow up on the dyno than spray oil under your tires and hurt your car.   Either way it would be awesome to see it getting the shit beat out of it again.  I'm too nervous to put more than 12psi to my grenade motor, I loved reading about you running 22psi and nitrous on top........frickin awesome!!

[MONTEGOD7SS]

The Ford guys get all the fun of splitting blocks in half and having the pieces held together by the intake and oil pan.  There needs to be something us Chevy guys can look forward to and find out what it takes to split a hunk o shit junkyard motor down the valley.  If that doesn't happen, seeing the crank fly out of the oil pan would be just as amusing.  A Wrench Rat twin kit with two 66s would probably get it done, but if not there's always the hose!  Just gotta make sure CC doesn't f up the test like Hot Rod or CHP did when they tried to break a junk ass Dodge motor with spray but couldn't do it because they didn't have a good enough ignition.  This needs to be what kind of POWER it takes to break it, and not let a bad tune or too much timing scatter it or melt a piston.  Oh yes, I will be tuning in for this one.

well then i'm giving it back to you, just don't charge me for storage.    maybe you can consider it my half of that parking ticket we got in seattle. if i ever get back up that way we definatley need to hit the bars again, that was definatley a good time.

great idea on everything as long as the nude pics aren't of you.

Hell yeah! Yep i need to vacation in your neck of the woods cuz seattle just wasnt long enough and my tranny problems in my Camaro had me running scared i wasnt gonna be home for work by monday. Well i hit up Glad at CC to see if he's interested in doing this so well see.

This is gonna be REALLY COOL to see the Grenade back in action.
I started my turbo build after reading the stories of this motor and then, when I found out that the motor I traded for was junk ..I got a second wind and started my own "grenade" of sorts.
It is a little more radical and ALOT more unstable tho...We are gonna see "just how quick JUNK will run".

Mine isn't quite finished yet, but hopefully in the next few months it will roar to life.
stock, half filled 350 010 .60 over block
Scat 9000 10/10 crank
5.7 pink rods with ARP bolts
Young's performance spec'd Cam Motion roller cam
Brodix -11 heads with Jesel shafts
C & S alky carb with elec floats and a 98.5 mm turbo

I don't really think it will live more than a few months, but it will be fun destroying stuff by going REALLY FAST.

Haha, that's awesome.  I have highlighted four things you are likely never to see again in a build, and find it hilarious.

ABSOLUTELY!!!! this is a "poor boy's learning tool"
I have no dreams of this thing living any longer than it takes to get some "good" stuff...just couldn't see not trying to tear some stuff up while I learn.

[flyinhillbilly]

you know if car craft wants to kill it i'd like to fly out there and pull the trigger on the dyno if they'd let me.

[il_wolf_li]

Marty, that sounds like an awesome plan!! 

[trbo355]

you know if car craft wants to kill it i'd like to fly out there and pull the trigger on the dyno if they'd let me.

Can you imagine explaining that to non car guy friends Hillbilly? " Hey guys i cant party tonight. I gotta jump on the red eye flight to Cali cuz i gotta blow up a motor tomorrow". . . .  . . . .  . . 

[wastingtime]

Hey Marty, just want to say that would be the best finish to the grenade.  Like stated, it would suck doing it on the track and risking your nice car.  That engine has inspired a few people to go outside the box, and try to go far on stock junk (me being one ).  It would be great seeing hillbilly pulling the stick on the dyno too, ha, too much.  Just make sure you guys don't get con'ed into cleaning up the mess!

Heh heh, i agree. Plus my car isnt safety legal to go balls to the wall anyways regardless of what motor is underhood.

[whiteghost]

Marty, I saw your kid's car in this month's carcraft.

It looked bitchin! Does he drive it daily?   

[trbo355]

Marty, I saw your kid's car in this month's carcraft.

Whaaaaaat? No kidding? I had no idea! Thanks for the heads up! My kid AJ has a learners permit right now and quite honestly, since the car came out of a field (where it rotted for 15 years) and has no title yet. I got it pre-inspected to make sure it wasnt stolen but a title cant be issued till all the major parts are there.
Seats, motor, trans and driveline have to be accounted for. The car came back clean so we built it up and now i have to take it back to get a title issued and prove we bought all the parts. Been so busy working and moving to a new house that its been sitting up in the air on a hoist for weeks now being ignored.
And yes, my kid has ants in his pants to drive it so i should quit torturing the poor kid and get the paperwork done. He will daily drive it to high school but plans are to look for a small 4WD truck as a more practical ride for winter and full time use. Plus he has already been "educated" on the fact that his Chevelle will most likely be broken a lot from beating the hell out of it all the time.
Did i tell you guys what it ran in the 1/4 mile yet? He agreed to let me drive it down the track for the first time since he had to know what it ran. I thought that was kind of a sacred thing for a kid to drive his own car on its first passes but his choice. LOL On street skins, 3.36 gears and junky 305 heads it went 13.97 @ 101. Not too bad and probably just right for a young whippersnapper to learn how to handle a pretty fast car.

[ProJunk]

I feel bad it never got shipped to him as i appreciate the hell out of the Car Craft article that came of his actions. Soooo, with his input and blessing, lets start doing a re-buildup this fall and inspect the whole thing for cracks, wear, lots of pictures ( possible some nude photos too ), new rings, bearings and ACTUALLY degree the cam for once. Cant think of what to do to up the power level past where it was though. More NOS is an option and i suppose a few more degrees of timing would kick it up another 40 or 50 ponies combined.

BIG mistake.  The only thing keeping that motor alive is the ring gap and blow-by.  Plus, you're going to ruin the magic holding that junk together if you actually freshen it with anything other than some more used bearings.  Inspect for cracks and wear??  Crazy talk.  You're trying to put the pin back in the grenade with all this silliness.  By all means put it back in the car and continue flogging the daylights out of it, but for the love of all that is junk don't treat it with any respect by inspecting it or freshening it.  You're running a cam that came out of a garbage can... degree it??  More crazy talk!  What this combo really NEEDS is an NX methanol nitrous system that uses methanol instead of gas for the fuel enrichment.  A one gallon cell with a dedicated fuel pump and regulator mounted up front somewhere would take care of methanol needs.  I'd want at least two nozzles in front of the throttle body, and I wouldn't spray less than 200 h.p. on it. You're definetely going to want to throw some timing at the motor too... methanol & nitrous LOVE timing when mixed together.

Heh heh, you sound like me talking about not "disturbing the magic". Only problem is i already disturbed it by removing one piston to take a peek. So what about gapping new rings plenty big and giving it plenty of bearing clearance? The crank really does need a polish as i rattled it pretty good on its last track run. By the time it smooths up im betting its gonna be a nice .003 main clearance and .0025 rods.
Im thinking a little love might not be a bad thing as long as the new rings take a good seal to the used bore ok. Thats the only uncontrollable factor with a freshen up but then again. . . . . . like it even matters.
