tvs 1900 OR tvs 2300???

[Jessika]

Ok, so I plugged it all into my handy dandy calculator.

a 1900 would be spun @ 18,600 rpms @ 6800 redline rpm. With a stock balancer size & an overdriven rear pulley setup. (I used serpentine 10 rib rear pulleys) Of course the calculation would be off depending on redline.

Also, another thing to keep in mind is that to acheive that, a ~3.2 must be ran on the front and that may require a 8 rib setup. So then you have the option of going to an overdriven 8" crank... so lots of options.

Yes, the 1900 will work just fine at 10lbs of boost & 6800 redline
if you know that you are not going to want to go bigger, then this should be ok.

so what is the diffence in an 8 rib design and a 10 rib? are there different variations of pulley size for each 8 or 10 rib? and is that ten psi on a stock engine or the cammed full exhaust engine? and why would you only be able to us an 8 with a 3.2 front pulley? sorry for all the questions im just trying to understand fully.

You can probably get a 2300 for about the same money as a 1900 plus upgraded pulleys. What are your power goals....now, and future?

10 rib is the size of the pulleys on the back of the blower I think. The faster you spin the blower (with a smaller front pulley) the more likely it is you'll have belt slip, so going from a stock 6-rib to an 8-rib gives the belt more surface area to grip.

well truth be told my car now is just a stock gto with full exhaust w/ stock cats and an intake. putting 355 rwhp. but next summer im planning to do a heads and cam setup which should put down 450 rwhp. then further down the line as money comes in i will do forged internals beef up the drive train and then put a blower on it.. my goal is around 650-700 rwhp.. I know im a big dreamer but i think my ls2 can pull that off with around 8-10 psi, guesstimated. and this will be some years down the road but that is the plan and i like to get all my facts in order.

we make 6 rib pulleys is just about all .1 increments from 4.1" to 2.8"
our 8 rib pulleys are only 3.2-3.0 and 2.8
our 10 rib pulleys are only 3.2 and 2.8

More ribs = more traction = no slippage at higher RPMs.
I believe the Camaro systems experience slippage with the 6 ribs at smaller than a 3.6" pulley with the 2300 and the 1900 would probably be about 3.4' or so.

I think that if you are are above 650crank hp, then just go with the 2300...

Its not really about the money IMO, both are expensive...
but if you go with a blower too big, then you will hurt the bottom end... not extensively, but it will be slower off the line than the smaller setup.
You can also look at the point that the car with the larger blower will have better traction off the line because of that lag...

Its really just splitting hairs at this point.

I agree with this and then you can't look back and say " I should have gotten the 2300 " I've seen it happen....fun either way though!

You're going to see slip on the front end before you see it on the back. When folks talk of going from 6 to 8 to 10rib, they're talking about the serp. belt and the pulleys on the front of the motor. You can spend more than a few bucks there. With the 2300, there's no need for pulley upgrades if you're good with 650rwhp and you're set up is "right".

Then you've got no business even considering a 1900. 650rwhp can be done with good heads on an LS2 with blower cam and 2300. I wouldn't try that will a 1900.

haha sweet that is all i need to know

[2010SSRSM6]

Will the 2300 even work with the LS2? I thought those required eiither a MP112 or MP 122?
