Killed the motor on the way home

[project89]

despite having some major ignition and fueling issues today i ran the car anyways.not to well at that.after the first 3 passes with almost no boost due to a bad boost controler i decide to unhook the wastegate for one final pass.this time i get 18psi about 200' out but all the sudden the car starts to buck and i hear a bang around the 330' mark and the car shuts right off.ok so after coasting most of the way down the track i get it restarted,no noise or smoke everything seems fine.Well about halfway home the car starts smoking out the ex system.so i take it over to the shop and do a leakdown test cyls 1 threw 4 avg about 21% well i get to cyls 5&6 #5 had 43% and cyl #6 had 57% :scratch: .im quessing the thing detonated so hard on that last pass that i broke the ringlands,or the rings :shrug: lol last time i try to run that much boost on a stock cast pistion

[enRo]

Well, I think I can safely say... I think you blew the motor when u had thoughts of turboing :lol: Good luck with it.

[project89]

lol no i blew it when i droped that bone stock motor in the car when i purposly blew up my good motor that had the forged pistion in it.thing that gets me is on the 2 passes i actually made it to the 1/8th mile mark i actually ran decent times
both in the 7.2-7.6 range.just couldnt keep the car under power the rest of the way down to track due to detonation and backfiring

edit make that 7.4-7.7

[PBodyGT87]

Thanks for selling us your excuses. My stock 2.8 runs faster than your turbo. Taking the wastegate off, not smart. To be honest, we all expected it to blow up.

But for now, I guess I'll go back to scratching my head about why the speakers in the headrests of the 85 GT haven't caused that car to burn to the ground. I wonder...

:lol: All in good fun.

exactly my na 2.8 was faster then the turbo 3.1 that is in the car now.that thing would pull consitant low 15.s.the first pass should have been my last but i was so pissed.i just wanted to get the thing down the track

[BigAls87Z28]

Forged bottom end + boost =boom
Weaksauce bottom end + boost = BOOOOOOOOM!

It was a matter of time. Taking the wastegate off...kiss of death.

like i said at the nats, ill put 50 bucks on Liz if you run your V6-T against her Fiero :lol:

um..yea, :scratch: i said it right in front of you. way to pay attention liz :lol:

[project89]

its quite alright atleast i got one decent 1/8 out of it 7.6@86, wish i could have made it full track on that pass should have been a nice mid to high 12 sec pass

[NJSPEEDER]

haha, tsar thinks people pay attention to him.

Do you have the book "how to turbo charge damn near anything"??

If so, I think you saved me 20 bucks jk

But damn man, It sucks I wish You could a pulled a low 12 pass.

[NJSPEEDER]

i listen to you space station :)

stop flirting with the communist

[project89]

lol so do i,but i should have known better to try to run the car with the problems i was having.theres always next time,ive got a fresh motor on the engine stand at work,just waiting on my aftermarket crank so i can assemble it

[Tsar]

But damn man, It sucks I wish You could a pulled a low 12 pass.First one must get out from 17's - i gotta say he talked alot of crap for someone who ran slower times then most stock cars run...

[Tsar]

stop flirting with the communist
dont be jealous timmay!

[project89]

lol well had it been an 1/8 mile track i woulda been fine on the one run,but ehh it wasnt,no big deal next time out i just gota make sure the car is running right.
ecm/ign,fueling problems ftl.dont forget i never made anything further then an 1/8th mile pass
had i been able to make full passes i would have been fine right down in the 12's/13's were i shoudl have been

makin fun of me alot lately huh vitals? a little insecure much?

[project89]

that kit needs to be rebuilt all together, with time and patience.

I'm such a woman.
the kit is fine minus the to atmosphere bov that i use,should have a cbv valve instead.but i had planned on having the speed density swap done by now which the to atmosphere valve would have been fine.as far as the boost controlle rnot working thats what i get for using a homeade one from a friend.what really got me was the fact on the 2nd pass withthe boost controlle relinates i couldnt get more then 4psi out of the turbo.even running on wastegate without the controller i should have had 9 psi.i didnt get any real boost till i bypassed the wastegate all togther :shrug: so there is deff a problem there somewere.though ill be dismantling the turbo setup/engine this week so ill find out what went wrong there.im not even gonna deal with the electronics issues.im taking that whole maf setup and throwing it right in the trash,this time im going right to the speed density system like i should have in the first place.

[NJSPEEDER]

dave, the way the car launched and moved down the lane, it looked more like no boost than low boost.
i hope you understand what it sounds like to people when you go through the ignition, ecm, bov, and wastegate as reasons for the problem all with in an hour or two of running 6 or 7 seconds slower than predicted.

[Tsar]

mike = correct.

Jake - no we didnt, but we can make up for it at the bbq :lol:

yeah i know.i couldnt build boost at all off the line for some reason i wa slucky to see 1 psi on the line even on th eburnouts i wa sonly pulling 3-4 psi , the car had boost but not like it should of. .i simply stated something was seriously wrong with either my wastegate,and my ecm or ignition moudle.on the one and only pass i had decent boost the car just shut off,which i still cant figure out why.im sure ill find out this week as i dismantle and inspect everything.im gonna need to take a good look at the wastegate and the turbo charger.the only other thing i could think of would have been a nice leak at one of the couplers but u guys would have heard that as i went down the track. did anyone notice the car smoking or anything on any of the passes?

[35thls1ss19]

where did you dyno your car to get those #'s? even if it did good in teh 1/8th it didnt look like no 400= rwhp car :confused:

[project89]

place over here in spootswood,mrc no boost = no power.done on the other motor with the good heads.the motor i had in the car today was just a bone stock 3.1.so it would have been lower at the same boost level.the only time that car felt good was the one pass with the wastegate bypassed.but that didnt work out to well lmao.i didnt care though by that point i was so pissed i couldnt get the car down the track.im deff gonna find out what went wrong and not make the same mistake on the new motor.

[project89]

[project89]

i 2nd that!! why v6's anyway. why not turbo a real motor?
i am im building a twin turbo 355 though thats on hold atm.and actually i like driving the v6 car more then the v8 car.

[NJSPEEDER]

which trouble would that be?
unreliable motor?
bad ignition?
bad boost controller?
bad ecm?

[Tsar]

and actually i like driving the v6 car more then the v8 car.
why is that? and dont tell me gas mileage...

[35thls1ss19]

yea why? this thread is very confuseing.... tsar i think we need some wayfast pictures to spruce it up! :-D

U forgot to add bad choice in motor selection.

Dude, you should just opt for an LS1 swap. You WILL save yourself ****loads upon ****loads of hassle, and its more HP for the buck. Im being serious too. Plus, you'll enjoy doing something productive with your car and not building ricey smallblocks/v6's on the side. Just my opinion.

:lol: im awaiting on those to be send to me by one of the members so i can begin chopping! :twisted:

[project89]

like i said its deff got ign problems,weather its limite dto that or its a bad ecm i dont know at this point.im betting on the ecm considering the cars got a new ign moudle/pickupcoil/plugs/wires in it,all replaced this week.when we threw the timming light on it it was actually pulling timming instead of advancing it>whgich could explain the poping in the ex.but that still dosent explain the lack of boost.regardless of timming i still should have had more boost

ls1 swap = to much money
sbc swap = i sold my last engine
besides that everyone pulles the v6 for a sbc,so i refuse to do it with this car

[enRo]

tru tru ls1>v6

Yes.

Im not saying that cuz I own one, and not cuz I love the N/A Torque on Demand... but it seems to me, Dave, that ur spending more time dropping in unreliable motors than driving the thing. This is just my 2 cents so dont take it personally. The only thing I see you getting out of these V6's is the fact that you are prolly the only one in a hundred-million that will ever touch the internals on those godforaken motors (sorry Liz :-P ) You will save money, hassle, and time just resorting to an LS1.

[Tsar]

um..well in that case its not v8s fault its just your iroc doesnt "rock" i guess. i bet there are a few people that will get better mileage out of their v8 on the highway then that v6t. what does that thing get?

[enRo]

ls1 swap = to much money

With the way ur spending money on these v6's, I think u coulda at least done an LS1/T56 swap twice. LS1 swaps can be done anywhere from $4000 - $6000, maybe more if u wanna go internally.

[project89]

Yes.

u know ur right but a v6 motor when i blow one up is around 100$'s the turbo system cost me next to nothing.compared to the cost of the ls1 swap the only thng internally i need to change in each motor is pistions,they already have forged rods and cranks.this motor would have had forged pistions but when i blew up the last motor i hurt one of the pistions,and didnt have time to order a replacement.due to the car also being a daily driver.everyoen has the good days and bad days.this was just a really bad day.mostly due to me being stuburn though.this is only motor #3.#1 was just to swap from the 2.8 to the 3.1.and the #2 was just cause that nigh ti got in a fight with the gf i purposly blew it up.this will actually be the first motor ive blown up in the car if ya get what i mean.

car = 800
turbo setup complete 750$
motor = 100 bucks
i didnt spend alot of money on it never have,the only thing ive spent alot of money on is the building of this 3.4.th eonly thing original being used is the 3.4 block.im waiting on my aftermarket crank to get that together.and hell even the heads i got for it i got for nothing.and any labor involed is free its just my time
im not mad i blew it up,its my fault but it was a bone stock motor as well,had this been the 3.4 id be really pissed

[Mike]

.due to the car also being a daily driver.everyoen has the good days and bad days..


how do you daily drive a car that you post about somthing new breaking every day.

[project89]

how do you daily drive a car that you post about somthing new breaking every day.
lol the **** that does break is all stupid ****, to be expected on something on something thats 17 years old
um..well in that case its not v8s fault its just your iroc doesnt "rock" i guess. i bet there are a few people that will get better mileage out of their v8 on the highway then that v6t. what does that thing get?
avg about 250 miles a tank

avg about 250 miles a tank
um..you might wanna rethink that v8=bad gas mileage thing. i get that in day to day driving, and i will get 300+ on the highway. :nod:

ohh. its an lt1 with 169k miles on it.

[Mike]

why not use a tta type setup (not its parts, but its layout) that way you can actually get a piping kit rather than fab up all that jungle-gymness

well to be honest when i first decided to turbo this thing it was never supposed to go this far.it was pretty much i got all the necassary parts,didnt have any kind of turbo car to look at,and put it together.it dosent mater anyway my problems weren't with the plumbing and layout.
this originally was supposed to be hey lets throw a turbo on it and run 5psi.but it just turned into more then that along the way

do u have 4:10 gears and a short tire on the car ? alot of the driving done with the car is intown as well,i tdoes get better milage on the highway though.

nope dont have gears, but i will shortly. which would mean i can actually use 6th gear in everyday driving! woohoo!!!

[project89]

I have a good 305 long block for you! :)
lmao no 305's besides the car will never get a v8,

[project89]

nope dont have gears, but i will shortly. which would mean i can actually use 6th gear in everyday driving! woohoo!!!
lmao going from the 3:42's to the 4:10s really hurt the hting as far as gas milage but its still not that bad

[WayFast84]

dave: what does your car currently get for gasmilage, turbo included

[Tsar]

lmao going from the 3:42's to the 4:10s really hurt the hting as far as gas milage but its still not that bad
ehh u must have a 5 speed. in my case 6spd ftw. 90ish mph at 2k rpm... gears wont hurt my in town gas milage by much.

[project89]

nope auto/with a 2,400 converter

[Tsar]

well um..4.10 in an auto trans, i found your gas mileage problem.

[Savage_Messiah]

4.10s auto here = 20 MPG with an engine thats blowing smoke

I have the older, better version.
How to Big Block Damn Near Anything.

[JL8Jeff]

Hey, at least you made it home. Although I think you were heading the wrong way when I passed you! :lol: I guess most of the stuff you've done so far has been dirt cheap so you can't really complain too much yet. A V8 swap has been beaten to death and I can understand wanting to do something different.

[BonzoHansen]

Put a Grand National setup in it. Woot.

[WayFast84]

[JL8Jeff]

Be original, go for the turbo'd Trailblazer straight six! Although, those engines are complete gas hogs for a 6 cyl. Maybe try a turbo'd Colorado 5 cyl!:shock:

[BonzoHansen]

VTEC!

[project89]

grand national swap is way to exspensive,and its been done more then a few times. jeff yeah when u passed us we had spun around to stop at that ****** lil gas station,was pretty much on fumes at that point.possibly why the car stalled on my final run lmfao.kasey i get about the same gas milage the rs only has a 12 gallon tank,thats why u guys are thinking the car gets ****** milage.

anyways i started to take everything apart today,didnt see anything obvoiusly wrong just yet,but was more concerned with just getting it apart then looking every thing over at this point.then again i didnt get into the motor yet,just took off all the turbo stuff,so in a day or so i should know exactly what happened

[NJSPEEDER]

do you have a fuel cell in your car or something? thirdgen tanks are 15.5 gallon, plus there is another gallon or so in the lines

[project89]

no it has the stock tank in it,everytime i fill it when its on e it only takes 12 gallons,maybe the gas gauge is just way off. :shrug:

[Mike]

maybe its special.

[Savage_Messiah]

like driver, like car? :lol:

[Rob WS6]

do you have a fuel cell in your car or something? thirdgen tanks are 15.5 gallon, plus there is another gallon or so in the lines

You sure about that? Ive been literally on fumes many times (ran out once) and it never took over 13.5 gallons no matter what. :scratch:

[WayFast84]

I ran outa gas once In my yard I think we filled only added like 4 gallons to the tank while the other two watered the lawn.. but never ever does my car see a full tank It might explode or somethin

[Savage_Messiah]

Tim, maybe you got confused, the 4th gen tanks are 15.5... (and i think later 4th gens were 16 or 16.5)

[V]

i was pretty sure 3rd gens were 13.5 tank and like 1 gallon extra through the lines and neck etc. 4th gens i think were right around that. There were rumors of a "1le" tank that held more for racing but people argue about that a lot, some say it just had baffling to prevent fuel starvation.

[Tru2Chevy]

Quick Google search brought up 14 gallons for third gen gas tanks.....
