What do you mean by reprogrammed ECU? Has it been rechipped? basemap? just get crome, hondata and get it tuned right that way you can tune A/F and timing.</TD></TR></TABLE> SORRY, I MEANT TO SAY CHIPPED. AGAIN, I BOUGHT THE CAR WITH THE SET UP ALREADY INSTALLED SO I'M FIGURING WHATS WHATS AS I TEAR DOWN THE SET UP. I LOVE THE RESPONSE IT HAD WHILE IT WAS RUNNING BUT WAS HOPING TO BOOST A BIT MORE, ANY IDEAS? I DON'T EVEN KNOW HOW MUCH HP IT HAD. I DO KNOW THAT NA B18s AND B16s WOULD GET SMOKED.

Yes, that's right. The top pulley was apart when I recieved it so I put it together the only logical way that I could see, but maybe it's wrong. Should the t-nut be in the adjustment slot with the bolt threaded through it? The tensioner screw tightens against that t-nut, correct?

So as in chipped you mean someone made a program for you S/C? If not you are doing more harm than good with it.

Yep love it running 450s its alot better than the FMU and you can up the boost. SHort of going OBD1 its the best thing you can do.

 

Ok sorry for getting in here late, but we have a few things that need to be addressed...First of all mechanically supercharged engines have a high intake to exhaust pressure ratio. That means most have a tendancy to be more efficient because of a more homogenous mixture. This happens because the high intake pressure helps to evacuate (aka: blow) the burnt exhaust gasses out of the cylinder, providing a combustion event in the "more perfect" direction. The better scavenging allows for more ease of tuning due to less combustion related imperfections. Supercharged engines can take more "compression" at common tuning levels because this improvement of charge setup, pre ignition.

I have a bunch of buddies with supercharged tacomas. Most are just running a TRD charger with stock management and 93 octane. Trying that with a exhaust driven charger (aka: Turbo) will net you more dismal results. True, turbos usually have more power potential per displacement, but that says nothing about efficiency, or BSFC (Brake Specific Fuel Consumption). Thus the reason for more supercharger kits out there for various vehicles.

"Naturally aspirated" engines use closer cam lobe timing to try and make use of the intake charge scavenging the cylinder. Also filling but we'll forget that little tidbit for now. Since supercharged engines have a "positive" intake charge, and a lower exhaust pressure charge, the amount of overlap a NA engine would benefit from now allows the clean intake charge to exit through the open exhaust valve(s). This reduces the amount of oxygen and fuel in the cylinder. The conclusion being that less overlap will help to produce more power.

MOST OF MY FRIENDS USE AFC's SO TO KEEP IT SAFER I WAS THINKING OF USING ONE.

Since jrsc doesn't make pulley upgrades for SOHC anymore or should I say nothing, I wonder if Vortech's pulleys work? Since my D16Y8 has a 4-rib Alternator pulley and crank pulley, and the one Vortech makes is also 4-rib it should work, right?

 

I just installed my blower and have a couple of quick questions
Setup:
88 CRX
D15 ZC Vtec
A6 crank uplley
A6 alt
JRSC w/ 3.4 4rib pulley
everything is lined up


My problem is that the belt is squealing like crazy. The belt tensioner is pushed down all the way. Any help would good

I hear this alot are BOTH idler pullies adjusted? Top AND bottom?

 

Okay, I've got a dohc zc that I bought a used sohc d16y8 JRSC kit for. I bought an adapter from zcspeed.com that the owner of zcspeed told me would work to mate the d16y8 JRSC to the dohc zc. The adapter seems to work fine, but here's the problem my installer, who owns a performance shop, is having. He wrote:

"Well we finally get every thing together and the supercharger pulley does not line up with the alternator or the crank pulley. I am returning the car back to stock as there is no way we are going to get the crank pulley to sit any further back than it is. It will rub the timing cover. Where have you seen this kit installed on a dohc zc???"

Any suggestions on what I might be able to do about this, or am I screwed?
Thanks in advance

 

I think if you read this whole thread you will find out the Y8 kits manis are offset. Did you get a crank pulley with the kit??

 

nah, no crank pulley with the kit. Looks like I'm going to go ahead and sell it though.

 

You can shimm it or so I have heard never had to do that. Or I would call Moss motors and ask them for the crank pulley. Or buy one on here I think they have the offset you need. The y8 JR crank pulley.

 

I heard about the shimming solution, but this is what the guy installing it wrote:
"The supercharger has a tapered shaft as well as the pulley. The taper needs to be followed as damage can occur otherwise. As well the key way would most likely stand a chance of being damaged over extended time as if the pulley would not be sitting properly against the key way as well an improperly machined (using a dremele) bushing."

Do you know if the y8 crank pulley will solve the offset issue?

 

Yeah the Y8 pulley from the JR kit the stock Y8 nope I have that on my car now z6 a6 y8 all have same offset. I meant shimming your crank pulley out. Probably not a option.

 

BUMP.. Anybody know the inside diameter of the nose pulley for D series JRSC?

 

5/8

 

subscribe to read later.....its late....

 

Hey guys, I didn't see any S/C'd y7's. I'm about to get a JRSC with a 10lb pulley in a trade. I'm planning on putting it on my daily driver. I suppose it was a z6 kit, what will I have to do with the crank pulley? Will there be alignment issues? Also i've been searching for a basemap. There should be a basemap dump for SOHC superchargers so we don't have to sort thru all of the turbo and na stuff.

 

everything should line up the only thing I would be concerned with is MC clearance.

 

thanks man.

How different would a basemap for a A6 be versus a Y7?

 

It would be off I wouldnt use it.

 

yeah I figured, I think the cams are degreed differently
