Put a small stall on a Procharger and the lag wont matter. I am going to try a TB stall with mine. My truck could use a stall anyway, a EC 4x4 is not light by any means.

A Procharger with a stall would be the fastest way to end the of the track IMO.

Put a BIG stall on a procharger and the lag won't matter. A small stall like the TB stall will barely help at all.

People who don't have centrifugal chargers seem to think boost lag is no big deal. It is a big deal on a heavy truck though if you're looking for low E.T.'s.

he's right. there's a big difference between a 2.0 60' and a 1.7 60' in chosing the right converter alone. often the same truck can cut both, it's just a matter of the right parts.

Exactly. Heres an example. My truck cut a 2.4 60' with the stock converter, a 2.2 with a TT3000, and now cuts 1.7's with the SS3800.

Yeah, but this is my daily driver and tow vehicle. The TB is the largest I am willing to go. Plus, my boost was coming in good at about 24-2600, and was pretty high at about 3000, so I think the TB stall will help a lot. I would love to be right in the meat of the powerband, but it is not practical for my truck. I would rather give up 4-5/10ths than give up a lot of driveability. My S10 has a 3k stall, and with a load it is very noticeable, I wouldnt want that while towing my boat. On a street driven daily driver truck everything is a compromise.

That's what sucks about the centrifugal, in order to get really good et's you have to give up towing capacity and driveability.

FWIW, I'm seeing about 11-12 psi at 6000rpm, and I see about 2psi at 2600rpm, and 3-4 by 3000rpm.

What pulley and blower are you using? I have a D1 with a 4.1, supposed to be 11psi, the most I ever saw was 10. The rest was about the same as what you are saying.

I'm probably gonna put a procharger on my 6.0 project. I just don't know if a Radix could feed a 6.0 with 9:1, cam, and minor headwork. Also, the off idle power of the radix would take away the fun on the street. As of now with my 5.3, I'm always spinning in 1st and grabbing second pretty hard. Just think how hard it would be to hook a radix blown 6.0 with TT3000 and 3.90 gears in a 2wd single cab!!!!!????
I think a procharger would probably be better for my application.
