Cam question

So I'm buying an ECS SC1500 supercharger kit and my question is, will my current cam work with it. I have a comp cam that was put on about 2 years ago. I was trying to find the exact specs on it but can't find them but back then I was told it was the most aggressive cam that you could get for the LS3 at the time. Just need to know if I can keep it in there. I read in another post that you can but you just won't get the full potential from the SC like you would with a blower cam. Any info would help.

Thanks

As you read in another post, the cam will work. It just isn't optimized for your setup. How much more HP would you get for an "optimized" cam? Who knows? 5? 10? 50? It all depends on the total combination you are running for an engine.

Get the ECS installed, drive it and if you decide you want more power, either pulley down, add meth, or get a cam speced to your combo. I did all three!!

I'll agree with 99% of what blake said. There is a small chance that a cam won't like a blower at all if the dynamic compression is way high. With the added boost you would not be able to run any timing/etc and in that case I would say a cam swap would have to be done. That being said, that is a rare case and you will probably be fine. Tuner would be able to tell. If the car is pinging like crazy and won't take more than 10 degrees then it may be an issue.

What springs do you have with that cam?
You could pull the valve cover and check lift if you wanted more info on cam.
Depending on the mileage the springs may be getting weak

Sounds like your cam may be the TSP 231/236 cam.

If it is that's the cam Birm is running in his ECS blown Camaro and it threw down some impressive #s on the dyno.

I'll check when I get home which springs they are....not too sure. They have about 10-15k on them.

If your cam is ground on at least a 111 or wider LSA with little or no advance ground in, you're OK. Even slightly narrower LSA or a little advance could work fine with a blower. At that point, it might be time to get the opinion of an expert though.

I'm running the TSP 231/236 cam (112 LSA) with the ECS 1500 kit. My car is putting down 636 rwhp and 581 tq with the restrictor in place and barely 8 psi on 91 octane. Alky controls kit going on in a few weeks hoping for closer to 700. The cam works great with a centri blower.

I just had an ecs kit installed a couple of weeks ago. I have a night fury cam which is 231/242 (113 LSA), dual nozzle meth kit and dual fuel pump. I put down 793 rwhp and 681 rwtq @ 16 psi of boost. Before leaving Lethal they installed restricter plate back bringing the boost down around 10.5 psi and rwhp around 730.

Which pulley did you end up with with the restrictor to get 10.5 lbs.? Awesome numbers by the way!

Thanks man. Its the stock pulley from ECS. Car pulls like a champ and I can feel the boost really kick in around 2500rpms (around 8 psi) and just keeps pulling like a freight train to red line(peak 10.5 psi with plate).

Cool. That shows the variances from car to car and the results of different parts combinations. I run a max of 8 psi on the restrictor with tsp cam and stock pulley. You are correct though, 2500 to 3000 rpm is like a kick in the ass! It does pull like a freight train from there to redline LOL!

He's running meth so a lot more timing which might be helping him build a little more boost and a lot more power, you're on 91 pump only.

That's about to change swiftkart! My alky controls meth kit is on the way to me now. Who knows when I'll have time to install it though lol. Gonna have it set up with an iat safety in the tune.

swiftkart you are absolutely right about the timing. It also helps that I am running 93 pump gas too.

Atmospheric differences can vary boost day to day also.

So what kind of safety did you go with if the meth stops spraying for some reason?

I'm at 2-3lbs of boost at 2500rpm but my kit isn't really an ECS kit. Its a Vortech tuner kit with a Paxton head unit. 7"/3.6" pulleys with 9lbs peak boost without restrictor. ECS uses 7.9"/3.33" pulleys I believe with restrictor. My car still makes great power but below 3500rpm it feels stock under WOT. ECS pulleys their kits for max boost so it will build boost quicker but restricts it so it will be safe up top.

True atmospheric differences can vary day to day.

As far as the tune the fuel stays the same on the four different tune options that Lethal gave me. The difference is the timing with of course the highest output being with the most advanced timing. The tune I left the shop with is not designed to rely on meth, and with the fuel staying the same is pretty safe. I have the option to pull the restricter plate and change tune to advance timing, but was advised not to run that tune everyday in mid summer with S. Texas temps well into the 100's.
