Novi 2000 Belt Application Guide

A recent post has brought up the need for a Guide for people trying to size up belts. Remember you can measure around the pulleys with a string to get a basis for length. Since we don't have the links page anymore all belt/pulley related info can be added to this thread. If anyone sees a pulley combination not listed on here, please list the pulleys and what size belt you used and who made it in a reply and I will add it to the list. Lastly make sure you know what width belt you need with corresponding pulleys, AKA 8,10 rib for serpentine or 30,50mm for cog belts.

7/3.5 5100568 Dayco Polycog

I use a Dayco 5080560 for an 8 rib 56.0" belt. You have to force it on, but you can get some serious tension before bottoming out the belt tensioner.

Can use the 1440mm 8M pitch HT - Gates Powergrip GT 2

Anyone else? Please post up what belts any of you 35mm cog users use. I know that is the common cog setup for passenger mounts since the stock idlers are wide enough for that width of belt. Please let everyone else know what belts have worked for you and what you've tried.

Anyone have a belt length for a 8" Crank and 3.5" Blower pulley(10 rib)

Are you talking about a passenger side mount Novi 2k? If so, that's a good one. I've spent the last 2 weeks trying to figure that one out. What it all came down to was, the closest way was to go to the outside of the idler pulley and the belt would need to be somewhere around 59.5"-60". The problem is Gates, Goodyear, and Dayco all make a 58.5" and then skip to a 61.75".

It wouldn't matter anyway unless you can figure out how to avoid the waterpump pulley. Even with a 93 Cobra waterpump pulley, it will rub. I shaved off .200 of my Cobra w/p pulley and it still wouldn't work.

What it comes down to is you will need an electric water pump AND have a custom idler pulley made smaller to shorten the belt so you can use a 58.5".

If anyone else can figure out another way, I'm open to suggestions before I void my warranty and just pulley it the old fashioned way.

Yeah, I havent heard anybody that was using the pulley combo and what belt size to use that is why I ask. I am not worried about the warranty since I am the second ower on the blower.

I am looking for a supercharger pulley to make around 15 psi on a free flowing 331. If anybody knows what pulley size and belt size I need it would be much appreciated.

Thanks
Jeremy

Well I'm looking for the same thing. I'll let you know when I figure it out. I'm hoping to have it running (and tuned) in a few weeks.

Yeah let me know what you figure out. I am looking around 15#'s of boost with my 331 w/ AFR 205's and Holley systemax stage 3 ported intake. I am looking for around 550 to the real wheels. I am suppose to be putting the motor and novi in this weekend and having it tuned next weekend. So I am trying to get the pulley before the tune so I dont have to get it retuned.

Jeremy

Mine won't be done by next weekend. Well, it probably will, but I won't have it tuned by then so I won't have any numbers to post. I'm in Oklahoma City and have to drive to San Antonio (10 hours) to get it tuned. It's going to be a weekend trip closer to the holiday. I've got some pretty decent parts, but my heads and intake aren't going to flow as much as yours. You should make closer to 625-650rwhp @ 15psi.

I emailed dayco about belt sizes and told them what I was looking for.

The size they said they had was a 10 rib - 60 inch belt. I am not sure if this would work or not, but I figured I would post the part # just in case if anyone is interested.

Dayco part # is 5100600

Jeremy

That would probably be really, really close though I think it would probably need closer to a 59.5". But you'd still have to have the electric water pump.

let us know if it works blown302stang so we can add it to the list. Thanks.

6.87/3.00 uses a Mac Truck belt #88GB452P555 - 10 rib

I need to know what belt for a 7" and 3.25" 10 rib paxton novi 2000?

If anyone has any ideas let me know.

Jeremy

it should be around 56.0 inches check your local parts store i believe they should have it...the oreilys and napa here did atleast

Thanks for the reply..

You have any idea about part #.

I have a Napa here local, but there are probably going to want a part #.

Jeremy

not sure on the part number...just tell them you need it to be 10 ribs and 56 inches...they should be able to look it up somehow

they dont make a belt that is 10 rib and 56.0, I found a 56.7 and that was about it, I think the one they had below it was like a 54?

Anyone have any clues?

Jeremy

I answered you on the corral, then I came to check here. I see you beat me to it.

FoMoCo1 and I live near each other and have been searching through all these different combinations for the past month for both our motors. I didn't think they made a 56.0". You may try to go outside of the idler pulley and lengthen it to around a 57.5". Napa has a huge selection of 10 ribs from 56.5" up. They have almost every 1/2". I was going to one of their warehouse stores that I have a friend who works at and buying about 10 at a time (at ~$15-19 each). I was originally trying to do a 8" crank pulley to not void my warranty, but that didn't work. Now I have both a 3.00" and 2.75" pulley.

Anyway... you'll lose contact area, but you may find one that works if you go to the outside of the idler pulley.

A tech at Paxton gave me the p/n for a Mack truck belt that is 55.5", 88gb449p555, might want to check it out, also the Volvo truck belt p/n for the same belt is 3895518.

Man thanks for the reply I will check it out and see if I can find one of them and give it a try.

.......

Hey I am gettin ready to go get one of the Mac Turck Belts, I will keep everyone informed if it is going to work with the 7"/3.25" Pulley combo.

Jeremy

i doubt it will fit....the 55.5 fits pretty snug on my 3.00 pulley.....although i have been wrong before

Well got some good news the 55.5" mack truck belt worked with the 7"/3.25" pulley. I did have to bump the motor over a few times to get it on, but it worked.

cool...let us know how much boost the 3.25 makes

I managed to squeeze a k080545 onto my Renegade setup with a 7 / 3.0 :)

do any of you guys have some part numbers for 30mm cogs that you could post for reference? the reason i ask is because napa and advance auto sell them but having those guys find part numbers is very annoying.

i'm not sure if you guys know but napa and advance auto suck for getting cog belts. for one they can never find the right part numbers and even when you give them the right numbers they may not be able to get it cause it's not in their system. and when they finally figure it out and can get it after few days of wasted time...well...the price is a joke. long story short i was able to get cog belts from a local industrial supply store for $25 and that's the price for a gates 1440 belt. i actually went with bando because they have a better selection and i was able to find the right belt for my 32/68 cog setup.

here are some bando part numbers if you guys have a hard time finding the right belt length as gates only carries a 1280 and 1440 length. and yes, i do know that they make a 1392 but it's a special order belt, meaning you have to buy a minimum of 10 belts (asp carries this belt for only $65, which is a great scam given that it's like a $30).

bando part numbers....
1304-8M-30H (163 teeth)
1360-8M-30H (170 teeth...this belt is perfect with my 32/68 setup)
1424-8M-30H (178 teeth)
1440-8M-30H (180 teeth)

hope this helps someone out as trying to find these damb things can be a major pain in the s.

Im going to being changing to a 3" blower pulley this year and was wondering what size belt to use. Im running the renegade driverside kit with the 8" crank pulley. Anyone run this here?

3.5 blower/7.0 crank using Dayco polycog part #5100555 purchased from
Ryder Fleet. 10 rib serp belt $24.00
Novi 2000 using factory brackets, single tensioner on 93 Notch.

You guys need to help me out before I can post these part numbers. It makes a difference what style brackets you use, because the length between the cog pulleys also plays a role. So I need to know the application, as in the bracket type and what kind of car its on, whether it was custom or what. Thank you for the recent heads up though in places to acquire belts at reasonable rates. That will be great help.

Hustler!
Well, you can add for an 8" crank and stock 3.5" novi2k pulley i used a 58.5" gates belt. shoot i forgot the pn. okay it's k100579. good luck. i'll let you know which belt i use for a smaller blower pulley when the time comes. Maybe this is already on here but I never saw it. Good luck!

I have a few brand new Dayco belts that I would sell if anyone is interested.
