I'm brainstorming putting a procharger on my car. What I'm thinking about doing is (since I'm fabing the brackets anyway) mounting the charger further out (forward) and runing a separate belt. The only thing I can't figure out is how I can get a 10rib pulley mounted up to a ls1 crank pulley. Does anyone make an aftermarket damper with mounts for another pulley?


Thanks

The 8 ribs are very tight. You're either gonna need custon fans or a way to push the radiator and fans forward(or the engine back). How much boost are you looking to push? The 8 rib SDCE pullies are holding very well. Also have you considered custom 8 rib crank and s/c pulleys? If you increased the size of both proportionally you could maintain the same flow with increased surface area for the belt to grip with. But I guess it depends on if you need that setup? Read up on the SDCE, I haven't yet seen someone hit the ceilling of that setup.

I don't have the clearance issues in front of the engine in my car. If it turns into too much of a pain in the rear I'll set it up in line with the stock pullies and use the 8 rib set up. But I was figuring on doing the 10 rib and changing the crank pully size instead of the one on the charger so ( like you were saying) I could get more surface area.

I'm not going to run an insane amount of boost. I was looking at between 15 and 20 after I get a forged short block in there. I want to get the system built and get the bugs worked out before I build a motor.

8 rib will be fine, what blower do you plan on using?

Probablly an F-1 but I'm not 100% on that yet. That was gonna be my next question.

I don't know what the heck I wann do right now. I'm at a toss up between getting a magnacharger or fabing a procharger kit. I know I will have much more room to grow with the procharger but the magnacharger will be soooo easy and cool looking. I should need to put down about 600hp to run low 10s in my car and that's what my goal is.

I could do it pretty easy now with a good set of heads and good tune, but I want to get away from the nitrous.

If you are stuck on 10 rib, ATI (not the blower company) makes a crank pulley with 3 mounting bolts for an external pulley mount on the face...

Ahh, I thought I seen it somewhere. That's great, they are local for me too.

Vortech makes 10 rib blower pulleys for Mustangs, I wonder if they have anything that can be adapted to their LS1 crank pulley setup.

By the way I suggest you either run a Magnacharger or a Vortech.

Get a procharger, I run an F1, its a great blower

15psi no slip

SDCE tensioner

660rwhp through a TH400 on 28" tires, and my converter flashes to 6200, yikes......

A new one is the plan before spring.....

Would be well over 700 with a 6-speed

I really like the magna but it doesn't seem to have the potential that the centrifical's do. I'll have to do some searching and see if it can hit the 600rwhp mark on a stock cube motor. I like the low end grunt of the roots style and the awsome looks under the hood.

I think that most of the Eaton-based setups might not hit 600rwhp, I wonder if you can get one that is bigger than the one that most folks use. I think most kits use the 112 or something like that?

Were you planning to run an intercooler too?

I think Vortech stuff is better, we all have our favorites, but a T-Trim can easily make 600rwhp and make over 700rwhp.

Oh, and who was the woman in your car pic in the calender?

Yeah I was gonna run an air to air in front of the radiator, I can get a 14x20x3 core up there. I'm gonna have to look into the vortech stuff. A buddy of mine has a 64 like mine but it's tubbed with a carbed small block kit on it @ 19psi and it runs awsome! I'm not sure which vortech it is though.

She's just a friend.

Carb setups are not as powerful.

For 600rwhp, you will want a Vortech T-Trim or one of the Prochargers.

I just talked to a buddy of mine that might be selling a ysi. do you think that's too big?

Hmmm, good price? YSi-Trim is a 1600 cfm blower, and it rated up to 1100 crank HP. You could pulley it down to like 10psi for an easy 600rwhp. I upgraded my blower from YS to YSi, and so far have made 700rwhp at 5000 rpms. I'm pulleyed for 17-18psi, and am running a T400, 9" and slicks.

T-Trim has 3.5 inlet and the YSi-Trim has a 4.0 inlet.

I messed up, he has a ys and is upgrading to a ysi.
I have a question though, when you step up on blower size what does it do with the power curve? The reason I'm asking is cause I want to keep a usable powerband for the street.
I'm an old turbo guy and don't have any experieance with the centrifigals yet. thats why I might be asking dumb questions.

It costs like a grand to upgrade from YS to YSi.

My old combo made 575rwhp at 5000. I made 746rwhp at 6900. I stepped up the cam, and upgraded to the YSi. YSi upgrade is supposed to be good for 30hp across the board. But with the bigger cam I am also building more cylinder pressure more quickly. I went from 230/236 to 236/246.

PSJ your combo sounds pretty sweet. i like the idea of the bigger cam to create more cylinder pressure. hopefully we can come up with a 10 rib on my LT1. we will see.

I'd have to do some research, but the 2.85 8 rib I am running might fit Mustangs too, so it's conceivable that the 10 rib stuff might only be difficult when sourcing the crank side.

Stock Vortech kit runs 8.00 crank/3.12 blower, I am running 2.85 blower. There is also a 2.95 blower out there too. I think I'd do like 12 psi with 8.00/3.12, I happen to have a 3.12 pulley around they are not very expensive.

I think 700rwhp on 93 pump with an 8:1 motor (I am 8:1) is doable.

CAPA in Australia do a crank pulley for an LS1 with mounts for a seperate pulley.

see pics of my pulleys, that i'll be using with my YSi which should arrive very soon..
