Well i setup my day for tuesday to get tuned. I still have my 7lb pulley on but used to have a 9.5 back 18months ago. I know that with my 9.5 i used the K070890 belt. With my 10.5 I bought a K070885.

I really should have posted this way before now but what do you think about my choice? Anybody out there saying it will 100% be ok or 100% not be ok? I really need to know now so I can "try" to drive around and pick up a few other belt sizes before tuesday morning.

**EDIT**

That belt size is 100% correct. the 885 is perfect for anybody w/ the 10.5lb pulley.

Also - here is the dyno pic and vid. Sorry but my scanner is messed up so I had to take picture of the dyno sheet so its a bit bent. Its an overly from my stock boost and my 10.5lb boost setup. All the other parts were the same except for the pulley change (and a retune).

PM or message NST, they're pretty good about answering quickly. NSTonAIM. Make sure you tell them what year vehicle the supercharger is for.

the other guy that has the 10.5 pulley said the K070885 will surely be fine. thats good news to hear.

 

That's the same belt I'm using, but I have the 9.5psi and overdriven alternator pulleys. I also have the stock sized water pump and crank pulleys, but those don't affect belt size.

I picked up a couple belts from www.rockauto.com. Quick shipping and reasonable prices.

 

^yup then that surely sounds like the size i need with the stock pulleys (other then the s/c). Yup - rockauto is where I got my belt from. Even with rush shipping it came out $10 less then the store.

 

Turned out I had to reschedule the tune for today. My end results were 268whp and 229trq - i have vids and dyno and will upload tonight or tomorrow.

 

Good numbers man, keep up the good work!!!

 

Ohhhh, awesome! Good to hear! I am planning on camming mine by the end of the year... need to pull the head off for various reasons, so I might as well do it all at once. 268 sounds nice!!! How does it drive?

 

waiting on vids and dyno sheets....

 

Nice #s

 

surely drives nicer - there is a lot less lag. Also - just the retune itself is making the car drive nicer. Nothing like a 40'ish whp and 40'ish trq gain to make things nicer.

Congrats .. those are some great numbers!

 

Thanks - I was hoping for atleast 255whp so I was happy to see such nice linear lines and nice hp # to match. The car was tuned so the methanol is pretty much there as a safeguard (and to keep #'s more consistant) - ....just incase it ever ran out I wouldnt have an engine left. Can't go wrong w/ cooler more dense air. I really didnt beat the heck out of it yet so I dont know how hard it pulls from a dead stop. All the traffic I hit going home I really didn't want to test things out with accident after accident of traffic.

 

nice work!!

 

goooood!!! what do you thing how much would be the whp without the meth injection?

 

pretty much the same thing - because i was pretty much not tuned with it. it was pumping but he didnt use it to push the tune like he could have.

 

nice numbers!

 

great, this gives me some numbers to shoot for when i start to swap pullies and tune.

 

12% 268+32= 300hp
14% 268+38= 306hp
16% 268+43= 311hp

12% 228+27= 255trq
14% 228+32= 260trq
16% 228+36= 264trq

300-311hp/255-264trq
