how to stop belt slip - 2003-04 Mach 1 Registry Owners Club

ls1 killer · 08-18-2008, 02:45 PM

wondering how to stop this......belt slip @5800 and up

currently a p1sc with a iw crank and 3.6 upper

should I..........

a buy a d1sc and go to a 4.0 pulley
b buy an 8 rib kit and pray
c di#k with more belts and tentioners??????

04azuremach · 08-18-2008, 02:49 PM

You can try a new tensioner and try a belt that's an inch shorter. I'm really surprised it slips @ only 9 PSI though.

NJ 03Mach1 · 08-18-2008, 03:05 PM

Or, spray the belt with VHT hehe

Sorry, Dyno trick to catch how much your losing thru slip...

Now that's funny. 23-24 lbs. of boost here on the street and zero belt slip.

And no waiting 10 minutes for the power to come on.

Too small of a blower pulley can cause the slippage. There are several options out there. You can go with an Reichad Racing pulley (http://www.reichardracing.com/pulleys.php ), an 8 rib setup (but this means all pulleys will need changed out), I remember seeing a manual belt tensioner in here, there is also a member who ran a cog setup (Linemup), or even a larger crank pulley and going back to the 4.0 pulley on the head unit. The issue is the lack of belt wrap around that small s/c pulley.

And to all the KB lovers out there who insist on bashing us centi guys, ask us about the effects of heat soak on our systems vs yours. Yeah I know the near instant boost/torque may be a kick in the ars down low, but the centi's pull on the big end like you wont see.

I love my centi, but heh, thats me.

all kidding aside....i love this arguement but if i had an f1a running 25psi you would be on crack if you dont think id be door to door with you if not eating you alive....you couldnt break 500 with 9psi....

but again i dont have an f1a so i still loose and i will always give you credit 700rw is 700rw whatever way you look at it....

i already have the iw crank on....i think im going to just buy a 3.8....this will just move my power band up and i should loose the slip...cheap fix until the bigger blower is bought

04azuremach · 08-19-2008, 11:30 AM

Does this mean I'm screwed with the 3" pulley I'll be using with my NOVI 2000?

no everyones situation is differant.....this seems to be the limit for pullying a p1sc... 3.8 unfortunately seems to be the smallest you can go.

FranktheTank · 08-19-2008, 12:31 PM

what size belt is on the car right now?

ls1 killer · 08-19-2008, 01:38 PM

109inch gatorback......i just talked to a guy and he told me to try a new tentioner and use a gates 109.38 belt.....so im gonna try that 1st

BTW GOODYEAR BELTS SUCK!

FranktheTank · 08-19-2008, 01:41 PM

109? wow...i have a 110 with a 3.7 pulley and IW crank...i couldnt for my life put on the 109.3

GUY IM JACKED!!!!......HAHA it def took some muscle

Zack · 08-19-2008, 03:09 PM

The problem lies between the alternator and PS pump.
I made a crude fix for such a problem a while ago and is still on the customers car with zero issues.
I know Lethal Performance was making an adjustable piece similar to mine but I think they lost interest in it. Might want to give them a call.

ls1 killer · 08-19-2008, 04:18 PM

thats pretty slick...im going to have a 2nd tentioner assembly tommorow i think ill give that a try.....at least someones using their noodle

no kidding but tell me how you are going to do that besides getting a bigger crank or blower pulley....theres no more room....

Madmax305 · 08-19-2008, 07:19 PM

Ls1 killer, not to beat a dead horse, But, this is exactly what we told you would happen with the P1. You are going to get "belt slip", unless you run a 4" or larger pulley. If you are running cams and a port/polish on the heads, you will never see over 10lbs with the P1.

I know I tried, I'm 3 years ahead of you on this one. My solution to the whole matter was to switch to a KB. I even went the whole 8 rib and IW crank, I STILL got belt slip with the P1. But, to each his own.

Zack · 08-19-2008, 08:02 PM

Belt wrap is good, but belt TENSION is better.
Flame away

If you want to alleviate most if not all of your belt slip, get a 98 Cobra timing cover with the good 3 bolt steel tensioner and the corresponding blower bracket. With 6 ribs and this timing cover, 18psi
(or more) is doable

ls1 killer · 08-19-2008, 08:21 PM

haha a new lil guru

It may help but its not the cure . Especially on a manual car . I put so much tension on my set-up that i split the rib right up the grooves on a brand new belt . With all that belt you cant help to get slip . Most of you have graphs from the tuner ask him for the datalog . You can see it when it starts . Its the nature of the beast . Yes it sux . Im the first and defenitely not the last to say it .

Cog it FTW !

Honestly i think between the 8 rib and a tensioner and some shims should just about solve all of your issues .
