1 - 8" crank pulley puts the belt practically ON the waterpump drive, even without the waterpump pulley. Its hard to imagine it working, even with a smaller pulley. Does anyone have a pic of this setup and how close the belt ended up to the waterpump pulley?
2 - The renegade setup comes with just the 4" 90 elbow for the inlet. It has a bung welded on it for the bypass to route to. How are people setting this up with their mass-air meters? Trying to avoid purchasing a powerpipe.
Thanks
Jeff
1. Did you tighten the belt? How long is the belt? I ran an 8" on my Novi 1000 and all i needed was a longer belt.
2. I'm pretty sure Vortech intended for you to get a powerpipe. Frankly i can't imagine having a blower without one.
1 - Ill look into that as well, although it would have to be A LOT longer :)
2 - Yeah, maybe... I think that I would have to modify a PP anyways, so I was hoping for something cheaper. The reason I would need to modify it is because the aluminum 4" 90 that vortech suppies with their renegade kit has the inlet for the bypass welded on as well, and its pretty big compared to the bosch setup - would have to replace the rubber one that the PP comes with and add a straight coupler.

1. I think my belt was 59 5/8" if i remember right......but this was a novi with a 3.5" pulley mind you......this should get you in the ballpark....
2. If you're crafty you might be able to come up with something better.
What type of car are we talking about?Quote:

Yeah, its a fox. I dont have the waterpump pulley - I actually got it to fit by using alonger belt. The waterpump pulley would not have helped, as it was the flange at the front of the pulley that was rubbing. The diameter of the pulley where the belt rides would not have mattered :(Quote:

I don't know where you might be hitting, but here is what my setup looks like with a standard crank pulley and a 93 cobra waterpump pulley.

hmmm....maybe thats why i didn't know what you were talking about. I thought everyone had an electric fan. :rolleyes: DOH!!! ;)
No, its not even that. The belt can touch the front curve of the waterpump pulley - not the belt surface itself, but the pulley near where the bolts go in.
this is with the belt tightened? either you got the wrong belt or something with the tensioner is wrong.
Yep, a longer belt will allow the pulley to pull the belt lower and further away from the water pump pulley.
Yeah, I think its clearing now with a longer belt, but im about at the end of my tensioner travel and I dont know if the belt is actually tight enough. We will see. I have to get it running in the next couple of days because we have another hurricane on its way.
it won't need to be hella tight.......if you get it tight with the 8" and 3.5" combo slip will not be an issue
Where can I get an 8-rib 3.5 or maybe even a 3.6? Im going to be making too much boost on my stock motor. :)
Oh, and where do you measure the diameter of the pulley? From the top ridge of one of the grooves?

Hey Jeff i heard they are evacuating already,man that is a big a$$ hurricane. I live in Houston and know all about them. Be carefull and goodluck man.
btw.....if you have to drive it, you can drive it with the blower belt off just in case no-ones told you. Just make sure the oil lines are leak free and head north. ;) I'd hate to be whatching a video of you and your car skidding along the beach and you're still trying to get that 8" pulley to work. :D
Yeah, were on the west coast, but still worried. Going to take the car to higher ground incase of flooding. The main thing I am waiting for now is a mass air meter. Its supposed to be in the mail to arrive tomorrow (Friday). Otherwise, I would have to pull the intake and put 19lb injectors back in. :(
If I cant get it done by the end of the day tomorrow - I have a friend with a trailor coming to pick it up :)

I have yet to install the adjustable FPR and with the 42s, its running a bit rich at idle and likes to surge http://www.tamparacing.com/forums/ta...s/icon_sad.gif Ill install that tomorrow and drop the FP a little to try to fix it.
Anyways, I have a very restrictive intake between the mass air and the blower inlet (something I rigged up in the absense of a powerpipe), so I think thats holding it back a little. The pulleys should be good for 14lbs and Im only seeing 10-11ish. I have some questions though:
1 - 1st and second gear dont seem to get much above 5-6lbs and generally, 2nd doesnt pull like I thought it would. 3rd and 4th simply haul ***.
2 - at the top of 3rd and 4th around 11lbs, right before I let off, it seems to pull extra hard all of a sudden - eh?
3 - after a hard run, during deceleration, it sometimes stalls for a second and the CEL comes on.. it will then restart. Seems like its loading up and stalling??
All in all - its added a ton of power. It drives like stock except for the surging.
I don't understang why you dont see the same boost @ the same rpm in every gear.
hows your bypass working? are you running the 3" and 8" pulleys on aT-Trim?
Actually, I think its at least a 3.33 pulley. Hard to measure those things, and there are no numbers on it, but it almost looks like 3.5
Bypass seems to be ok. Its a race bypass. I had a flange fab'd up and welded it to the aftercooler. FYI - if anyone is looking for silicone hose to connect their race bypass and renegade blower inlet, get the fuel neck silicone hose from a local parts store. Its the same stuff used for PWC gas filler necks too :)
