: What would you feel comfortable spinning the TVS1900 at?

I have a few questions, at the risk of exposing my lack of knowledge.

If I were to put a bigger shot through the throttle body plate, would this increase the spin rate and stress on SC rotors?

Also, how do you determine what it is spinning at?

thanks in advance.

Nitrous modifies those values in the charts.

Curtis i would wait and just use the 2300 blower i will have ready in less than 2 weeks. It should be a drop in kit for about 5k total. Then you can spin it to the hills and back...

I'm guessing that right now since you're only pushing it at like 9psi you still have all the flexibility up to 14-15psi right ? I'm guessing your blower can stress your motor with an over abundance of boost but your built block is not putting any extra stress on your blower. BUT with the amount of $$ already invested into your motor I'd just do the 2300 and not look back. It'd be a real b*tch if that 1900 did anything to your current kick@ss motor

Also, if it is important, I am only running 9lbs of boost with a 150 shot.

Raz that is my concern but I need to have the house painted this year and I just replaced 2 hot water heaters, last week. I am trying to not do anything for a bit with the car.

How does Nos modifiy values? You can only spin a blower so fast till your overspinning it.

Right there with you. House is sucking my car money out of me

FWIW 22-23,000rpm I would be concerned past that

Well this is what i am trying to determine. If the boost level is indicative of spin rate. I am comfortable putting a little more nitous through it.

I considered, dispersment rate to each cylinder with a slightly larger shot. I called Nitrous outlet and they told me a 250 shot through this plate would be fine..
I have the jets.

Nano system requires an increased fuel jet, So that tells me more nos is going through the same Nitrous jet.

Check the plugs at the track for fuel ring, heat range, timing etc.

I just want to make sure I do not overspin the tvs1900 if the boost still less than my LSA (14psi) vs LSX (9psi) will I be ok?

The nitrous does cool the SC as well.

22-23,000 is how much boost?

22-23,000 is how much boost?

Depends on a number of factors. I think your right there at the edge. With the displacement, heads and cam your running and spinning the motor I assume 6500rpm + your done. With a 10" ring and stock upper your spinning the blower 3.26:1 with a 2.55/8.6 combo your at 3.37:1. Just multiply your engine RPM by your ratio and it tells you your rotor RPM.

If it were me I would dial in what you have and save your pennies for a blower upgrade maybe next season.

yeah it cools the SC, but rpm's are rpm's. Nothing you can do about that.

Right your are Domsz06

Think of a prop in the water, after a certain rotational speed it no longer moves water it just cavitates. Same with the rotors, at a certain speed they no longer move air they just chop it.

Curtis your boost pressure doesn't matter, psi is just a way to measure the restriction. You have already tested on your personal car that a 2.55 upper wasnt happy with a 9.1 lower and it still wouldn't be. The blower can only do so much and you are at that point. With a 400+ motor you need more than a 1900 blower. I think you will want more than a 2300 unless you are happy with no more than 200 more hp.

can you say 3.6L KB?? :D :D

Curtis, personally and I am sure I will have lots of people flaming me, but you built the motor, boost the crap out of it and stop spraying....


But that's just me.

Thanks all. Good stuff from everyone. I learned alot from your replies.

Right now, $ is tight. I will play with what I got this year and try and get everybit out of it, before I change anything.

Thank you for the calculation.

I had my shift point reduced to 6200. So assuming it shifts at that point everytime, I am looking at approx 20,909.80 rotor rpm.

At 6,500 shift point were talking 21,921.56 rotor rpm.

I wouldn't waste my money on a 2300. But that's just me. I would do a KB 2.8 before a 2300 anything.

I had called kb several times and they said basically they want nothing to do with this market. If it is to be done, it would be no warrenty, no support, no nothing. We would have to make everything fit on our own, with all custom stuff like brackets, pulleys, lengths ect.. So i moved on from the kb option.

The route im going with now is the exact 2300 blower i have on my 2005 caddy that let me hit 1200 RWHP on. So im sure that will cover 100% of everyones hp goals.... What the blower cant do, the nitrous will get you there...

Correct, the reduction in engine RPM changes rotor RPM at the rate of your ratio.

After this weekend, if you get a clean pass you may come to the conclusion that all you need is a freash set of clean underware :-)

Again I would work what you have, the NOS is making up for the lack of boost.

Good luck this weekend, keep her straight and matted to the floor

Contact Whipple, they already make a 2.9L for the 2010 Camaro. IMO, well worth the extra money to get the twin-screw to work over the TVS 2300.

I'll do my best and let you all know how it goes.

We will be looking into making a kit for the CTS-V in the near future. We have a few other projects to finish up first.

The 1900TVS unit will only support so much power. Even with spray you are still covering up for the blowers inefficiencies once you spin the blower past its adiabatic efficiency range. At a certain point you are just chopping hot air....

We do have blower options for this vehicle (2.3L, 2.6L, and 3.6L). These blowers are much better suited for high HP applications. Their efficiency level is great for making big power.
