What pulley you running and what boost are you seeing? Front/Front?

Yes, I am starting to think that as well based on the responses in here. I'd like to wait and see if one pops up in the classified section. Although, I'm not sure what all is needed to get it on a 99-02 truck.

i have the front driven. with iw 8 rib set up with crank and 3.2 pulley i see 10 psi. With 2.7 i should see 15-16

and what will be the difference in feel at part throttle between the 1900 and 2300 on a 6.0? Someone here who switched from 1900 to 2300 said it was harder to make boost around town?

my 2300 hits hard if i go off the line the truck burns out 1 2 and 3. i have no problem geting boost on my tbss with it.

The question really isn't if you can get in the boost. The saying from the other member is that he preferred the 1900 for DD. My motor is stock for the time being, so I really don't forsee needing the extra boost capabilities of the 2300. But maybe it is more efficient at the same boost levels and produces less heat?

i wouldnt put a 2300 on a stock truck anyway. the 2300 starts to shine above 10 psi and 1900 for a daily driver is fine.

A TVS2300 doesn't need over 10psi to shine. At 8psi we made over 550RWHP with a 6.0L at work and Allen Nelson made 672RWHP at 8psi. Mike Mcginnis made around 615 or so at 10psi and when he uppped to 14-15psi his gain was minimal. More boost doesn't always make big power. Just some examples, but the point is the TVS2300 makes plenty of power at 8psi and just because it will make the higher boost, it doesn't have to in order to make good power. Too many are concerned about the boost number over the results from the boost number. I've also driven both and would take the TVS2300 over the TVS1900 for that cubic inch level. The TVS2300 made boost just fine around town when needed. I have logs showing this. I couldn't buy a blower knowing that if I wanted to turn it up I'd have to overdrive it. A 6.0L that already has ported heads and longtubes is only a good camshaft away of making it hard to achieve 10psi without going to a bigger crank pulley on a TVS1900. Some would argue this, just look around at those using it.

Agree on the 2300. I drive the "Allen Nelson" 672 rwhp setup quite often. 100 + miles today. If the smaller 1900 blower makes boost quicker, it would have to be extremely quick. Matter of fact, I don't think it can be any quicker. Cruise in 6th gear at 1500 rpm...just a slight amount of pedal pressure gets you into boost. You really shouldn't use a butt load of boost at low rpm anyway. But it's there. I can't see a down side to the bigger blower. I'd bet you can't measure the hp difference it takes to turn the 2300 vs the 1900. There doesn't seem to be much difference in price between the two. I'd probably lean toward the bigger blower even on a 5.3L. They make bigger blower pullies, don't they?

Even if you don't plan a high power rig, your market, should you decide to sell, is bigger with the 2300. What's the price difference between the two?
