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.

The 1900 can reach your goal of 650-700,weve made 647 with a 122 and ls1,but the 2300 could do it a little easier...I recomend the 1900 up to 600 rwhp,it can do more but you have to get real picky.For 600 to 800 rwhp you should use the 2300...If we can help you with any part of your build and the blower give us a call,weve done a few

good read. . . lots of info... but i'm still lost. . .

but IMO. . for $600 more.... why not get the 2300.

because the smaller 1900 may provide boost a little faster..

when you say not carb legal thats pretty much just california right? what states do the carb test?

[bluegoat05]

California Air Resources Board ok well i googled it and thats what carb means. so i answered my own question. but is there any other state its not legal in? and whe is the mp112 different?? just curious

I am not sure which states require CARB certification for registration, but our certification does cover all 50 states.
Alabama and Texas I believe do not...

I would never limit my future so therefore I would go with a 2300 if it was me

[Jessika]

states that require California emissions –
1. California
2. Connecticut
3. Maryland
4. Massachusetts
5. New Jersey
6. New Mexico
7. New York
8. Oregon
9. Pennsylvania
10. Rhode Island
11. Washington

thanks for the info.. but what makes the difference? why is a mp112 pass and a tvs 1900 or 2300 wont pass on an ls2? and why will they pass on an ls3?

It all has to do with what we have filed paperwork for. When the GTO first came out we only had the 112/122 available so that is what the CARB# covers. After the introduction of the LS3 we had transitioned to the newer TVS units so that is what was certified for the LS3.

FYI - on anything not a nasty stroker motor the TVS1900 will make MORE power than the TVS2300 in a apples to apples comparison.

I make 660RWHP in the desert heat on a LS2 at 10 PSI with a TVS1900, and my AFR is in the low 10's. I can still throw an upper AND a lower pulley at it.

91 Octane, No meth, No spray.

Hendrix and BlownChevy have never pointed me in the wrong direction, take what they say as fact.

PS - 6 rib with no belt slip here!

I think Hendrix recommended the 2300 at HP levels over 600rwhp (post #113). My thoughts exactly. Your results are pretty amazing. Congrats What else was done to your LS2 besides 10psi?

wow very impressive numbers! I am also very interested in what else you have done to the engine?
earlier in this thread someone( i THINK it was hendrix) said they were doing an apples to apples test between the 1900 and 2300 and said they would start a new thread... does anyone know if they got that finnished and where i can find it. because i would really love to see how different the torque curve is on paper.

[TPEHater]

The TVS1900 will make 700 RWHP on a 6 speed car blower only, I'm just not sure how far past that it will go.

The debate of which blower to use should not be based on just power level alone, the blower should be properly matched to the engine and the airflow it has to feed. The TVS1900 is slightly more efficient (just slightly) on a stock displacement engine.

If you want to make big power, you are probably going to go big cubes also, and that is where the TVS2300 will get with it.

My car is just heads/cam/blower, however keep in mind that my heads are damn near the same CFM as a box stock LS3 head.

All of this sucking through a stock airbox and only a 1-3/4 header letting the motor breathe.

It has some left in it dialing in the AFR, and I have a 2.7 upper pulley on it now (the 660 RWHP run was with a 3.0 upper), but I have not had it on the rollers since.

Here is my TVS1900 torque curve, pretty much vertical. The car made 40 less RWTQ on this run than it does now.
