Mild/aggressive cam help I want an agreesive cam for a street car. It's a summer toy that I will take to the drag strip once or twice. Below are current mods that will not change much.
01' Z28 A4
Yank 4K stall
LT's, Y-pipe, cat back, no cats
3.42 gear
LS6 intake/ported tb, SLP lid.
I am actually going a little above on the cam swap, pulling the motor, replacing lifters (Think I have one going bad, 113K miles), rod bolts, Oil pump, timing chain.
I want to stay with my stock 28lb injectors.
I always liked the (Revers split) TR230 230/224 .575/.563 111*
other that I'm considering, SI5 231/237 .589/.595 112* or the TR230/236 230/236 .592/.602 112.
Which one is best for my mods?
I don't want to rev it to the moon to make power, I want to be able to knock some dicks off from a stop light as well. I want to be able to feel the power right from the get-go and keep pulling until the shift.
I have heard them all on youtube and like them all equally.
Any input? real world experience is welcome.
Again, this has to have great street manners, make power, and sound good. I want my cake and eat it to.

For starters those 28lb injectors need to go. General rule of thumb is you dont run your injectors past 80% duty cycle.
Secondly, if you only go to the track several times than a big donkey dick cam aint the way to go. It will get walked on by people with smaller cams that have much better avg power rather than peak hp at 6800+rpms
Edit ** im wrong with the reverse split**
I had a 228R and it is considered a smaller/milder cam. It was great on the street, didnt have shitty manners and still put down the power. Now you can go larger and still have a good street car. It just depends on what you want and what you can tolerate.

The reverse split would be ok if you got stock exhaust, otherwise thats not the way to go.

So each of the cams listed will have over 80% duty cycle? Have you had experience?

Mid to low 230's are "donkey dick" cams? Interesting. I guess the played out term "donkey dick" is a relative term.

I can tolerate enough, this isn't my first rodeo with a sports car with a little nut, I just want an agressive street cam like stated. I have a 4K converter, so my RPM's are going to be higher when I hit it. I don't have to make alot of power under 2.5K, just enough to drive it like I normally do when not getting on it. I want a cam that has alot of power between 3K and 6.5K. at least alot more power than I have now.

I would need to have a good explaination why it's worth the extra money to go that route over the rest.
Anyone have any track times with the EPS stated above on a cam-only bolt-on car? Dyno charts?

Yes, actually I do ive had multiple h/c lsx cars, and any sponsor here will tell you thats a good rule to go by. Have people gone past that? **** yea, but its not recommended depending on what you gow ith and your hp/rpm you may be beyond that number. my 228R maxed out stock injectors

No, nor did I saya 230s cam is a donkey dick cam. maybe it was unclear, but when you said aggressive that generally entails a large cam (high 230's - 240's)

If you are willing to put up with that then I'd suggest EPS cams like suggested earlier, Texas speed, livernois, Martin @ Tick has some great cams now too.

DO NOT ORDER FROM THUNDER RACING, search the sponsor feedback section here for a good list of reasons why. They are not even sponsors anymore.
My advice? Call Geoff at EPS who used to work for Thunder Racing and even designed the TR230 and let him set you up. He is more than willing to spec you a cam for your needs and get the order in for you.
If you don't track it, something high 220s intake and low-mid 230s exhaust would probably work well.

Thanks for the response, I think your numbers are right in line with what I'm going for.
Anyone have any reason I shouldn't go with a reverse split, other than what was already mentioned?

+1. Seems like you are hung up on the donkey dick cams, go with this one. Your car will move out well at the track but feel like a turd on the street. If you are dead set on sticking with 28# injectors, make sure you are dead set on picking up another motor while you are at it.

Pat-G put a baby EPS cam in a ls6 crate motor ,it made 430 rwhp .the car runs 11.20 in Texas.be careful changing your rod bolts.do it 1 bolt at a time .get new gm bolts ,or take a chance with Kaltech bolts.seen engines making 410 rwhp with stock injectors.the TSP torquer 3 will make a little more power ,but needs better springs.

Search the many threads on the EPS cams and dyno graphs/results. That there will give you every explanation why. You get what you pay for. Like mentioned, even the baby EPS cams produce amazing results. I picked up almost 50rwh with mine through a M6 while I was still running the LS6 intake. It's a torque monster as well.

Check out Martins cams @ tick performance. Street heat and sns torquemax cams for ls1s. I have just about the exact mods you have and went with his sns stage 3. Specs in Sig. With a 4000 stall your gonna be reving on the higher side no matter what. 3000+ to really start hauling. So don't get a cam with to much power under the curve... you essentially won't be able to benefit from it. Match that converter wisely. I was little lost on this, I had to call Martin.
