So here are the correct pieces:

ATI 918856 or 918856W 450.00 VS 325.00
ATI 916227 or Lingenfelter L220170709 135.00 vs 170.00 (ask summit to get)
Damper bolt ARP multi use or ATI 951499 torque to yield 45.00 vs 9.85 Summit
Gates belt HD ? NO clue

I assume stock supercharger pulley is 7.99 OD vs 9.34 OD a difference of 1.35 shorter belt needed?

What belt ya think? K080845HD


Another thing I noticed ... ATI measures top rib where Lingenfelter measures lower the difference of 9.34 ATI or LING 9.17..

Crap is confusing

Another thing to note. ATI is who makes Lingenfelter's pulleys. They just market it as their own. ATI 15% and LPE 15% pulley same exact thing minus branding logo.

I went with the K080842HD belt. I did so because USP45 mentioned he had slip with that belt and the 9.17" pulley. But others have mentioned they don't have any slip. So I figure a 1/4" shorter belt shouldn't hurt anything.

One more thing. Lots of people going with the HD (heavy duty green back) belts. Gates came out with a newer improved series called RPM which is apparently better suited for a supercharger.

There is a K080845RPM available.

Quote from Gates on another forum:

RPM (Racing, Performance, Muscle) is a new, no compromise belt built specifically for supercharged applications.


Whereas 99% of all belts on the market today use a polyester tensile cord, the RPM series uses an aramid tensile cord. This is the same fiber found in bulletproof vests and is 10x stronger than steel and 5x less elastic than polyester. When polyester heats up (which it does even from normal use) it will stretch out. As you can imagine, when that belt stretches out you experience belt slip and boost loss. Eventually the elastic properties of the polyester will fail and the belt that was once 100” will stretch to 100.25”, at which point the tensioner can no longer compensate for the stretch and generally results in belt failure.



Due to the strength and minimal elasticity of aramid fiber, the RPM series of belts will not stretch which allows the belt to maintain its true length throughout its service life. This results in more consistent boost and in some instances, users have reported a 1-2psi increase merely from switching from HD belts to RPM belts. We actually have some user submitted under hood video on our Instagram page (GatesRPM) that clearly demonstrates the difference between polyester and aramid corded belts.



Another main benefit of the RPM line is the use of two layers of adhesion gum. These layers create a sandwich around the tensile cords which transfers the load to the strongest part of the belt; the jacket (or smooth backside of the belt). FleetRunner HD belts got a reputation for strength because they use one layer of adhesion gum, standard micro-v belts forgo any adhesion gum.



RPM belts also utilize a patented rubber compound with the highest coefficient of friction available and are built in common OE supercharger sizes as well as many sizes used with aftermarket setups. The RPM line has expanded to 299 part numbers with new numbers being added every quarter.

So RL carriers conveniently loses shipments and then sells them on Ebay?
What a racket!

I agree. That's why I let a shop do all the damn work for me. Btw, doing MSD wires on Friday. Upgrading to the 1LE tail lights and brake lights and installing a Phastek under body glow kit. Upgrading my rear lighting to Diode Dynamics as well.

Still waiting on wheels. Once those come in, BMR's get installed, car gets settled in. Then we go fuel and cam and blow shit out the park and add nitrous.

I'll never use another wire other than Firecore50. I've had multiple sets of MSD's come apart and not last.

[EDFHOBBIES]

Well I can't stand a shop to over charge on parts.. most these shop don't take the time to setup accounts so they source from Texas speed, marryland speed, or Bryan tooley.. then they add 20 percent.. or they don't buy the volume..

Also I hate paying for work and parts when I can do it..

I modded 3 cars In last 2 years about brok lol

Ran those on my Vette. Honestly, we don't even need to upgrade wires, but I wanted them changed anyways, so I said just get me a set.

My SS made 670 with a 2300? Why wait for the 2650. I ran 10.33@135 with a 2300. Its wicked fast with more to come once I get the Lt4 injectors and we should be at 740 rwhp with the 70mm pulley.

Truckers (and their delivery customers) do dumb stuff, like take the wrong pallet of the truck... happens all the time. If they leave it somewhere it might sit for days or weeks before it's found again.

So if RL lost that shipment and paid the freight claim to compensate for the lost goods, then RL bought those parts. If they later find the lost shipment, then they have stuff they rightfully own.

What would you do if you were RL? Yep, you'd probably ask Whipple if they want to buy them back again. When they say no, you'd be stuck selling it on Ebay.

Some of us didn't want to do a cam. You won't be that high 93 only to much compression. You will have to mess w meth, c16, or e85.. running into same problem w wife's car.

The 2650 would add 100 hp plus just by itself with out messing with headers and cai ect. Just take off and install it .6k for blower minus selling your lt4 blower (zl1 owner) for 1500 to 2k comes out pretty cheap plus room to grow. A lot cheaper than the lingenfelter kit (pulley, cai, belt, crank bolt, damper) $1200, 1200 to 2000k for headers, then a tune..

Plus room to grow... 2650 will move the most air cooler.
Rather have new technology and not waste 6k on the 2300 for that much money.

That's pretty good my manual 6 5th gen TT ran that at royal purple a good track Hennessy track was in 11s .. if your doing that in a auto your slow.

For a 5th gen that's correct. 9.17" is 18% for 5th gen, not 6th gen. 9.17" for a 6th gen is 15%. Call Lingenfelter yourself and ask.

I've already spoken to Vengeance racing multiple times on the matter, so one of them is grossly misinformed it seems.

[djfury05]

Literally every other vendor advertises 9.17" as 15% also. Look at Innovators West who manufactures their own dampeners and uses Metco pulleys. Or better yet call ATI they're who actually designs and makes the pulleys not Vengeance or Lingenfelter.
