what Cam? LS3 with TVS2300 shooting for 600+whp

[TPEHater]

While I do realize that my car is an LS2 and not an LS3, the very slight displacement difference is about the only difference they share.

First, for any motor under 400ci the TVS1900 will get to ~700 RWHP more efficiently than the TVS2300.

For fuel with the TVS at that level (e85 or otherwise) you can look into having your injectors modified vs paying big money for the hard to find LS3/7/9 style injectors afermarket. I took my LS9 injectors that shipped with my TVS kit and had them modified to flow ~103#/hr @ 58 PSI for about $20/injector.

Also when looking into fuel, you can get MUCH more capacity and life out of converting to a return style system instead of adding dual pumps or a voltage booster. My single pump @ 17 volts was spent at 650 RWHP SAE, I went return style with the same pump @ 13 volts and it held 660 RWHP SAE, then I added a second pump for insurance and lifespan. I am not sure if the Camaro fuel pump is difference, my point here was meerly an example of the benefits of the return style system. Also on the return style system you can run a 1:1 boost referenced regulator that will grow your injectors under boost.

As for your power goals, I run a LS2 with Trickflow 215cc heads which are a VERY similar head to the LS3 heads on paper. I also have a cam, which we will get to later, and 1-7/8 headers with dual 3" exhaust. I have no meth and on 91 octane make 660 RWHP with a 10:1 AFR (very very fat for some testing we are doing on our TVS series boost controller), this is done at 10 PSI currently. I am very confident it has 670-675 RWHP in it at 10 PSI and will break 700 at 13 PSI.

The cost of the build is no where near $15-$20k, about half that unless you are paying labor.

In response to the original question at hand, which cam to use. The cam I have is of the Hater cam series, the same grind that was put in another members car and was rumored to be some monster lift cam by another vendor on this forum. I have the cam card for mine and am positive it is not at all. It is a very well mannered street cam that makes good up top power (I pull to 7200 RPM with no fall off) and is very smooth.

I can't sell you the cam, or the boost controller because I am not a forum sponsor but I can answer any technical questions you may have about your build.

I have felt no bucking yet, I drive the car as if it were stock. I launch from a red light as if I have no cam and am out for a daily drive not even getting on the car, it is very mild manner. If you were never told the car had a cam and could not hear it, you would never no. They did a great job tuning the car. They are in Longview but 85% of there business is either out of state or town. Steven is easy to talk to and will help you any way he can.

if you think the 14 cubic inches of displacement is the only difference between an ls2 and ls3, you need to go back to the drawing board.....

I have a cam that has a nice lope, drives very well and makes the numbers your looking for at only 7 psi boost.

The LS3 Made 736 RWHP at 12 psi with a Vortech YSI and the L99 made 623 RWHP at 10 psi with a Maggie.

It won't take much of a cam or much boost to make 600 RWHP with a Maggie on an LS3

We have one with my cool Idle blower cam that made 604 at 7 PSI.

How do the numbers compare between this smooth cam and the lopy blower cam you have?

I believe they will be very close just different Idle and Low speed, even though both my blower cams have good low speed torque.

very interesting point. Ive read here that if you are going to install a blower only with everything else stock, then go with the tvs1900. but people recom the tvs2300 if going to do other mods (ie cam, headers, cai ...etc) I dont think we will grow in the future, so just cam + bolt-ons. so would you say the 1900 will be more efficient with these mods? will it produce same power with the two different superchargers? I dont think so! but would love to hear it from you and others.

I still didnt order the tvs2300 as im still not sure what size pulley are we going with.

as far as injectors... we will probably just buy new injectors and sell the ones that comes with the kit, which will be brand new. that should cost the same or close to the cost of modifying the injectors!

thanks for the info on the fuel pump... I think we will just stick with 91oct and avoid any modification to the fuel pump. bap should be enough with the power level we are aiming for.

also see any supercharged cars running a boost controller and thought it wasnt possible, but i was wrong. just went on google and found that there is a way to run a boost controller on supercharged vehicles... learning new things everyday!!

thanks for all the advice and informative post

seems like you have a blower motor to play with. can you get solid #s with both cams. Ill be dropping one in this winter on my e-force motor. would love to have a nice lope but I always favor go over show. if its close, no big deal. gimme the lope. want to hit 600 next year. cam and smaller pulley. like 530 rwhp isnt enough. Its a sickness!

Yes I do.

I am really looking foward to putting one of my new blower cams in with an Edelbrock blower I think it will really help the boost climb flatten out.

thats worried, I PMed ETMC and asked them about the stg2 cam, and that I need no bucking after 1000RPM, and they told me to stick with the stg 1 (since it will buck up to 800RPM) thats why I assumed the stg 2 will buck up to 1000-1100RPM. who tuned your car? I know that you can smooth the ride a bit with tuning, but you feel no bucking at all! are you sure you have the stg2 cam? thanks

can you PM me a price of the cam kit and also what bap did you guys use and how much do you sell them for? this is taking too long I want to order everything, but need to figure out what cam and what size pulley

I have the ADM stage 2 cam and it sounds alot like the ETMC cam. I think it drives like stock and seems to work well with my maggie. Just a suggestion.

ETMC did my whole car, tune and all. NO bucking
