No. The ls7 uses an interference fit between the dampener and pulley plus the high torquethe bolt isunder places a high clamping force on the pulley. We ran the stock one for about 8000 track miles with no issues.

We never had a 2500rpm knock. But then again we aren't using the stock dry sump system.Plus the car was retuned from day1 with HPTuners.

Interference fit seems like a REALLY bad idea for crank and cam pulleys. I mean, they're making it work, so it must not be that bad, it just seems...sketchy

I think it was an oversight by gm. He'll the eforce supercharger comes with a kit to "key" the crank. Meh... It is what it is. Gm gave me two additional years and 40k on power train so.

Any lurkers on that have messed with tuning a boosted car? I know it's the wrong sub forum but I'm about to pull the trigger on a demon2. Looking for some reassurance.

remember... stock bolt is 180LBFT plus a further 90 degrees of bolt rotation... Nothing is going to move around when it's under that much clamping force. The ARP bolt calls for 240LBFT plus 90 degrees.

IIRC on the supercharged motors they had to key the crank snout to insure that the supercharger wouldn't cause any sort of belt or pulley slippage. I also don't see anyway that you could cut the crank snout for a woodruff key while it is in the car, maybe they simply use a set screw with the kit?

PM me with a detailed breakdown of your issues. We are personal friends with the GM southeast distribution rep along with a few people from the racing side of GM and other people from companies like Katech, MTI, and so on. I'm curious to see if anyone else has heard of these issues happening in rapid succession on the same chassis. Did you buy the car new? If so I'd say you might have a case with the lemon law vehicle reimbursement/replacement deal.

what will you be tuning with? typically a demon is only used as an emulator if you can't read/write in time directly to the ecu

but on a good note I'm smashing out unpacking and organizing the garage like a boss... Only one more corner and my toolbox to go

Dallasb84

Damn! I did that all Sunday clean clean clean.

I actually wouldn't say I'm at all upset with gm. They have lived up to their warranty plus some. I haven't mentioned the tr6060 they rebuilt as well! It's just my experience is this. I probably put more mileage in a loaner than in the vette!!!! Which is also nice!

I was bringing up the Neptune rtp demon thing.

Yea GM has always been good about taking care of Z06 owners.

The goal is to be able to get a second car in the garage. Civic is in the garage because I told the landlord itwwould stay inside unless there was something I had to do that involved me rolling out outside. The county is weird about having non operable vehicles outside, especially since the civicis basically a rolling shell. They are also weird about cars without valid tags which is currently all but one. There's 4 cars in thedriveway but the accord is getting scrapped and the Porsche is being sold as soon as i putcatson it so then the element will be the only one outside.

When I bring my s13 over it's going under the porch. I'm picking up a friends miata soon so the driveway space is needed. Also if I can snag this mint starion widebody roller I found then the SVT focus will go outside till I get the starion pretty enough to sit outside and not get attention. It's a complete car motor, interior and all but I don't plan on using the stock motor but if need be I can Gerryget it running wellenoughto qualify as operable and since it's emissions exempt I can go on ahead and tag it then theycan't say ****. It'll run by legal definition but just be ugly for a while lol

Dallasb84

The struggle! I had the vette as DD and the teg as my toy. I get a lot of weird looks when I tell people that. Especially when I would drive the teg to work on race days. I bought a gmc crossover to blend in so to speak (trailer the car and have comfortable room for track days).

I'm really thinking about going the DIY tune. Or at least do it/figure it out myself. Give it a shot. It should be super fun or frustrating. Hopefully some people can coach me along. My local speedway rents for 50 bux for four hour blocks to groups of two or more. Maybe go that route to dial it in.

Harness is almost done, i resized all the wiring removed the fan switch, distributor wiring, oil sending unit wire, v tec pressure switch, and a couple more in the cabin harness.

More work tomorrow

That's pretty crazy. I'm perfectly fine with just zip tie'ing the extra wiring off and leaving it alone. That whole opening the harness to **** with it thing...nah, I'll just spend a few hundred on a harness from Chasebays or whatever before I do all that.

My obd2a harness is totally stripped and whoever at Honda assembled it musthave been drunk... Wires crossing around each other over and over.

I have more harnesses and ecus in boxes than I care to think about.

Dash harness, body harness, fender harnesses, and engine harness for the civic and the stock ecu and my aem ems
Engine harness, body harness, dash harness, fender harness es, and ecu out of my EM1
Body harness, dash harness, tucked engine harness, and ecu for thes13 and sr20
Wiring harness and ecu for my vg30dett
Spare ecu for the van

And I just ordered two ecus for the focus on top of the original one that failed. I'll probably use that case to fit a Megasquirt 3 Pro in so I can retain the stock harness... An engine harness in that car is not a cakewalk like a civic. Mainly due to the total lack of room under the hood.

Should have said something back when I was trying to source a new harness, ******

wantboost

iTrader: (2)

I didn't know lol.

Irony is I have to run a different harness for the standalone so I really have no use for it other than emissions.

Part of me really wants an 88-91 sedan but I really really really want an RT4WD Wagon. My high comp turbo y8 idea would make for an epic setup in that platform, traction galore... Imagine the looks on peoples faces in the mountains on a road course when they get blitzed by a civic wagon through corners.... TROLOLOLOL

Nah. Once you get into it, engine harness seems pretty simple. I can imagine it would be pretty easy to make with the engine out of the car.

turbohatch96y7

iTrader: (15)

Harder with the engine out. You need to make sure all the sizing is correct.

Once youve read the diagrams its very simple to do.
I de pinned all the ecu connectors but no scare since i know where everything goes


If you know how to work a soldering iron and have all the right stuff its easy.

LightningTeg

My thought process was with the engine out you can run and tuck the wires to the engine to whatever sensors they need to go to and then all your worried about is the pig tail back to the cabin.

wantboost

iTrader: (2)

Yea the engine side is easier to do out of the car, you just have to wait to do the large sight portion back tothe firewall . Especially if you're shortening the harness or adding amphenol connectors or doing both like I am .

To a point it's also a bit easier to loom the harness once you have the motor or a mockup motor in the chassis as hoses, piping, lines, and other components could change the way the harness is run.

Ill take a pic. On my specific motor (b20 or any b series)

The only sensors hard to reach is the alternator connector and the injector harness. Thats not hard at all when you think about it. Then the ect, iacv ,iat , vss ,coolant sending , unit cop harness and epm harness is all in front of you.

If it was a bone stock motor with all the emission crap yeah it might be a pain in the ***.

Once you open up a stock harness and lay out how its routed, just luke want boost said youll be like " this **** is looping back and forth" and it all makes sense

So I've made the decision to pull the motor and trans out of the accord before it gets scrapped. I'm already taking the wheels off and the audio out. As much as I want to keep it as a literal beater I just don't have the room. Figure I'll keep the long block for a rainy day, despite having a little over 245k on it it's a good motor, just has a few bad valve stem seals, a leaky rear main,and things of that nature. I'll definitely sell the auto trans though. Despite the mileage (i suspect it's had a trans put in it, guessing 60k on it from owner history) it shifts like it was brand new so I can definitely get a couple bills for it.

Could you imagine some lightweight Honda chassis with even an all motor high compression f22a1? Would make a fun track ****. I'm seriously debating renting a garage at the track soI can have a dedicated shop space and free up the garage and driveway a bit. Maybe see if I can keep a shell at my dad's shop (doubtful fml)

Best part is since the chassis will likely be crushed I don't have to be gentle pulling the motor. Likely end up cutting the axles since the CVs are fucked, unbolt the upper core support and cut the lower out and jusy roll the chassis away from the motor lol. Especially since my hoist is in storage.



The spacious engine bay will make it even easier once I get all of the accessories out of the way, might pull the head off first so I can just jack the car up super high and pull the block out.

Meh, the single cam F's just never did it for me. Being able to pull a motor and not give a **** is nice, though. When I pulled the D, I said **** the axles, and just ripped them out of the CVs. Hearing those ******* pop out felt good.

The A1 head stock ports flow like a ported b series vtec head. They love to spool big turbos like no one's business.

With a better cam, intake manifold, and even the most basic of stock internal turbo setupsthey make obscene amounts of torque
