Procharger Pulley D1???

[JadedGT]

Would call Terry at Beefcake he will get you setup. I am running about the same mods with a D1 and a 4.75 pulley should be hitting about 700 on the dyno next week.

So I use a Gates #K080660 (1691mm) for a 4.5" pulley. It is tight but works great.

Here is the Gates catalog.

There is a Gates #K080670 (1716mm) but I think it is too long. I used the Bando 8PK1705 which is (1705mm) with good results. They can be found on Amazon for a good price. I would try that one.

I have a 5.00" pulley with a D1 and am making around 12-13 psi. Does that seem right?

Altitude? And at what rpm? what are you measuring Boost with?

 

[Chummel]

700-1400 ft. 7500 rpm. I have a boost gauge tied into the procharger vac tree. And have had it hooked up on a dyno as well. Also have long tube catless Headers.

Seems about 2 psi high. not sure why unless the boost gauge is slightly inaccurate.

 

[Chummel]

That's what I was thinking but I have had 2-3 different gauges on it at one point or another 12-13 on them all.

I have a D1 and make 12-13 on a 4.10 pulley at 7400

You must not be on the Stage 2 kit, right?

Nope, I have the stage 2 kit.

I have the HO kit.

 

[MyLilPony]

I have the HO kit.

HO pulley's are different than S2 kits. If we run a 4.10 it's like 17/18 psi

I was talking to the guy I quoted running the 4.1 pulley. That doesn't really exist for the Stage 2 lol.

Ahh I see, that makes sense. But I'm still seeing more boost than I should for the 5.00 pulley, right?

I just bought Sai li's fuel system so after I get that installed and tuned for E85 I will hop on a dyno to see power and confirm boost (again).

More boost than normal yes. Most don't see it that high with that pulley at that rpm.
