Eric and I swaped in the UR6 plugs then took it for a test ride. I did half a pass at DonJulio raceway. 1st gear ran great up to 5000rpm hit 2nd and ran it up to 5000 hit 3rd and then let off. I heard a little back fire on decel, gave it a little gas and it was missing. I got about 4 house away from mine and the RPM's drop real low and it just died. It will crank but then it would just stop. sounds like I dumped a rod. I was just talking about selling it too, been thinking about getting out of thirdgens.

Hope it doesn't rain any time soon, because I'll be on 2 wheels for a while

So it's not cranking anymore?
I call dibs on door panels, booster pump, and anything else I can think of.

Well if it is in fact dead, it will be a bummer to lose a long-time 3rd gen owner/member.

You sure haven't had much luck getting one on the road for very long.

P.S. - Were you really running 10psi? I'm hoping to get closer to that, if not a bit more.
I'll have to get back to you on the extra pulley/belt you have before you sell the whole thing!

iTrader: (2)

I see Eric's little wee-oh-five dance went as planned

Serious note : 350 build time, not give up time

kairles

iTrader: (2)

I had a 12psi pulley on, but I guess procharger rates them at 6000rpm. I would get 10psi a little over 4000rpm at full throttle.

TraviZ Im not gonna part the car out, Im 85% sure Im gonna stick another motor in it. I still wonna make atleast 1 good pass down the track . I am thinking about selling most of the swap stuff I have for the Iroc.

Vash Vega

why won't you just get the iroc fix camaros look better,put a 355 or a 383 stroker in it with that procharger our yours and you'll be happy

Don't you know that cars have feelings? She was ticked off at you and decided you must be punished. This is the the equivalent of talking smack about your girlfriend, so she takes your ATM card, empties your bank account and goes on a shopping spree.

Vash Vega

don't leave the thirdgens they are some beautiful cars and imo look better than most of these new cars out there.I wouldn't mind owning a 5th gen tho man irs and factory real duals lol and a 69 look to it

kairles

iTrader: (2)

I know same thing happened with my Iroc. trans went then a month after I had it rebuilt the motor took a dump on me.

JesasaurusRex

iTrader: (3)

so you just changed the plugs but changed nothing?

Ramair21

iTrader: (3)

You cant leave bro! Its time to take that motor out and rebuild dude! Never give up on these cars. If you treat it right they will do the same to you.

It took awhile for the LS1 to like me but it does now. LOL

iTrader: (1)

ya ran great and pulled hard till POP

changed the plugs for nothing

3rdBird

iTrader: (1)

I'll let ya have mey motor for a grand. Ill even throw in the 700r4 for an extra 350 bucks. Remember thats the combo that took out Bennie & Del hahaha

iTrader: (4)

Why don't good motor deals like this ever come around in IL!

Jeremy_84_F41

iTrader: (3)

Damn, that sucks. I'm glad to hear that it ran hard, so at least the supercharger is still in good shape. I agree that you needed some tuning on that thing. Did you retard the timing or anything else? The stock injectors like to lock up at higher pressures too. SVO's would have been a good upgrade.

I'd say replace/rebuild the short block, get some bigger injectors, retard the timing... and you'll be good to go for a while. I don't know what the specs are on the L98 in 3rdBird's car but I have my stock L98 that ran strong that I'd let go pretty cheap. Since you don't have to drive it I'd say pull the engine out and tear it down... I'd especially like to see what the pistons look like.
----------
$1000 for an L98? I'll give you the same deal and I'll even pay shipping if you're really that excited about it...

campin1983

iTrader: (4)

I guess I should look at the details first. I sort of assumed it was at least a somewhat modded 350 with low mileage, same with the tranny.

kairles

iTrader: (2)

timing was at the stock 6*, and I had the ford 22lb pink top injectors.

Im doing some math right now to see what route I wanna go.

vindeezl

iTrader: (2)

I think she's beggin' for a 350.

Or...

Get a PNP motor to send her on down the way so you can get that damn IROC fixed.

Either way you roll I'm down to give you some help bro

JesasaurusRex

iTrader: (3)

this the same motor that you pulled spark plugs out of that showed tons of detonation?

Slouch

Rubs it in...

kairles

iTrader: (2)

it was bound to happen sooner or later, Im surprise it lasted as long as it did. I will mis the second gear powerslides on the freeway onramp by my house.

JesasaurusRex

iTrader: (3)

im not rubbing anything in, i'm asking a question because i don't know. I'm assuming by that responce it's the same motor tho. May i ask what you did to fix that situation after you pulled those plugs?

Vash Vega

i know what you mean but if you need any help on your car im down to help you specially with the iroc you need to get that bad boi running

kairles

iTrader: (2)

all I did was change the plugs. never heard any knocking or pinging. even before the plug change, just felt kind of soft, and the whole WOT 4500rpm problem

87tpi

iTrader: (5)

You can always get this one and charge it.

If I buy another car it will be fairly new

87tpi

iTrader: (5)

Yeah, I like having the 2 newer cars and the Formula to play with.

JesasaurusRex

iTrader: (3)

now the rub in part, just because you didn't hear it doesn't mean it was there. The spark plug is your only view into the combustion chamber and they don't lie. That motor was detonating, a shame nobody told you sooner.

porkyzilla

iTrader: (1)

the plugs actually look like they had oil on them and like the guides odd part was it was only the drivers side

1TUF92Z

It detonated and that's why the engine broke. 10-12 psi on a stock 305/350 is a little much more than I would run it for. Even the stock Mustang 5.0 can't really take 10-12 lbs of boost and they came with forged pistons stock. And to rub it in, the 302s are pretty stout.....stock.

Vash Vega

yup they are a lil faster but they are ugly @ss hell and can't handle corners for ****,2 weeks ago i seen one spin out trying to hit the corners to fast

TraviZ

iTrader: (2)

And like most 3rdgens on the road, they are not maintained and do not perform anywhere close to stock.

iTrader: (5)

My old 88 Gt wasn't bad. The power was nice. Travis and Eric saw it.

TraviZ

iTrader: (2)

Ya it rocked.
:salute: Steves brother.

Vash Vega

yup you ain't lying about that this 5.0 iroc the other day was backfiring like crazy and was trying to race a c6 corvette all up on his tail man i wish i would of recorded it,that corvette walk pass his @ss like he was standing still
----------
what you do with it??.I swear them stangs look like suited up escorts with a v8 in them

TraviZ

iTrader: (2)

escort with a v8 would be sweet.
cosworth anyone?

iTrader: (5)

Kid pulled out in front of me and I t-boned him. Got $6,000 out of it though so it was ok.

kairles

iTrader: (2)

My formula was well maintained, never leaked a drop until I started boosting it. I shoot down a couple 5.Slows with the mighty LB9

if everything goes as planned it should be back in the road in about 2 months

Vash Vega

so what you going to do with the iroc

OUTATIME GTA

iTrader: (2)

Glad to hear you didn't lose the 3rd gen love completely yet.

You should've tuned it immediately after adding the blower IMO.

kairles

iTrader: (2)

I don't think you can tune the 730 ecm for boost because it can't see boost. I would have to repin the ecm and run the $58 or $59 code. which doesn't sound hard, but they dont have a way to control egr and Im not sure it would pass smog with out egr.

OUTATIME GTA

iTrader: (2)

Not necessarily just for boost, but you could still optimize the fuel/spark and reduce the knock.

I don't know a lot about the 730, but there are some great articles on the DIY board if you have a couple hours to read.
I know you're trying to datalog and that's a start.

The AIR and EGR will not function, true. But there would be no check engine light, and if you leave the valve in place when they push on the diaphragm to check its operation, the engine will stumble like it is supposed to since it will still subject the intake to exhaust gases.
