I am really considering putting a cam in my car in the near future. I have been doing a lot of research on cams, how much power they make, times they run, and driveability. My car is a daily driver, so I am not looking for anything too radical, but I want to run close to 11's w/o heads and close to 400rwhp. With heads, mid 11's and 420rwhp. I was looking at the TSP torquer cam, which seems like it will fit my needs as far as power goes, but it seems a bit big for a daily driver(233 .589 112) I have been flipping through some of the GMHP mags and seen some LS1's making good power and running crazy times on smaller cams though? For example, the issue with ronnie dukes car, there is a Z28 (the green monster),6 speed, in there that runs mid to high 10s on just heads and cam, his cam I believe was 224 228 I forget the lift, but it was on a 13lsa. I just picked up this magazine, the best of tech, and its all about the LS1, they have all the quickest cars, with a 6speed, cam only, heads and cam etc. Well the fastest heads and cam car was a formula with a small 218/229 .560/.560 13lsa, the car obviously has all the bolt ons and a lot of weight reduction, but it runs 10.50@128, its an auto though(4,400 stall). Still, with that small of a cam, that is very impressive. The only thing I can come up with is that could it possibly be the 113lsa? I always thought the lower lsa for NA cars atleast, the more power there is to be made, but maybe the LS1 responds beter to 13 lsa? Can anyone help me out here, this maybe a really stupid question, but if I can go with a smaller cam and make the same amount of power with a little bit better driveability and be more of a sleeper car, then im all for it.

 

I run in the mid 11's with my setup but not without juice.

 

1 degree less lobe separation is not a big deal. It will lope very slightly less if you could tell at all. No I do not think that 113 is the number you should look at. I am also in the hunt for a cam, and my main focus in on duration. My car is also pretty much stocker, and daily driver. 13.3 at 109. I am amazed by some of the cams people on hear are putting into these LS1. Maybe I am thinking way to small. I am looking at a 222/222 566/566 112 cam. Good power comes from all three cam specs. Just look at some of the stealth cams with 116 lobe separation. My car has to lope though.

 

I am actually going with a 113LSA cam on my new setup. matching it to a 110icl expecting 400RWHP through an auto.

 

I have a 220 0.560 on a 113 great mid range and with bolt ons and tuning there's probably 425HP at crank available. About 390-400hp at the wheels on USA dynos

 

The cars you speak of have run these number quite a while ago and are very lightweight. I think you will see some crazy numbers coming out of these new big cam setups soon. I can't get over the T-Rex Cars running 11.1s with stock heads at 34XX raceweights and 500+ das. Hell my car with a 27" tire and 4.11 gears (too much tire for my gear soon to be changed by running again with my 4.56s and spool) ran 11.66 at 117.xx in nasty DA conditions with a 230/236 107lsa cam. I was only cutting 1.69-1.66 60's. I didn't know my raceweight at that time as it was a bit less then my best 11.62 at 117.98 weight of 3545. This is on stock heads.

I don't think 113 lsa but only a very little part of the equation. To run a small cam like that and go fast you better have some excellent flowing heads.

 

Hmm, so I guess I better just stick to the TSP torquer cam. I want a lot of torque, something that reminds me of my old L98 vette, first gear was wicked in that thing, then on the bottle!!! But today I was racing an E55 AMG, damn those thigns are quick, it wasn't really a race due to traffic, but I had to play catch up and lets just say there was no catching up. With a decent cam and some bolt on mods though I coulda pissed him off by showing him a set of Z28 taillights to a car that is more then 5x $$ my car! I wish some people had some numbers and track times with the TSP torquer cam, I guess its still relatively new though. Thanks everyone for the replies, I figured the 1 degree of lobe seperation wasn't much, but im just looking for a nice stealthy setup.

 

that LSA is just a number. depending on what you want to do it may or may not be what you want to do. The .050 numbers dont really tell you that much once you start pickign cams apart.

I did a 228 intake duration cam, that happened to be a 113 LSA, that made 400 rwhp from 6000-6400 rpm.

Is TSp still using comp lobes on their 233/233 cam?
