Which cam to meet my goals? TR230/224 or Trex?
 

My goals are to hit 11's cam only on a bolt on m6 2002 camaro and still have decent street manners, Im going to be getting a 9in rear later down the road with 4.11 gears but might do some roll racing on the stock rear end with 3.42 til I save enough for my rear end......

mods will include-lt headers,3in y-pipe,lid,ptb,e-cutout,slp dual dual,suspension,drag radials and later rear end and gears

I was set on a Reverse Split TR 230/224 .575/.563 111 LSA because of its low end and street manners.

But now Im on the "go big or go home" mentality, really leaning towards the mighty TReX v.2 - 242/248 - .608/.612 - 110 lsa , cause of its high end and with alot of gear and a good tune it would be driveable on the street.

This will be on my weekend car, what are your guys thoughts on these cams?

That's a big gap in cam there pal haha. I am all for big cams...but you don't need a Trex for 11's. Look at the Trak cam or their 230/236 .592/.602 112 cam.

Yeah I cant decide if i want tame or big, Im going to test drive a trex cam car maybe by this week.

Big cams are funnn. But if you're not into stalling out when you hit the brakes too hard. Or stalling out when you turn too hard. Trex isn't for you. But if you like retarded power and revs, it is haha.

this should be a good thread GM MEXICAN!! im also up in the air on cams just like yours. honestly, im in between the X1 or the MS3!! i know alot of people say under the curve and bigger isnt better, but i dont want to be to conservative and spend all this amount of cash to be conservative. i do want a beast. plus man with cars getting more powerful and faster i can see to go bigger. but my car is an A4 though. so i hear i dont have to worry bout big cams being dogs down low because of the converter. hopefully we can get more feedback!!

its all in the tune, there are a few guys here who daily drive this cam

Im going to give thunder racing a call tommorow

tr 230/224 111lsa!!!!! trex is outa the question thanks Thunder racing!

Go big or go home?.... my balls :eyes:

I say go for the reverse split, at least if you're sticking with stock heads. Aftermarket heads, go for traditional or single pattern.

Unless you have the supporting valvetrain/suspension (which is a bit), stay away from the monster cams in my opinion. You won't benefit from their full potential.

so if were to do heads wether it be some trickflows or maybe some ls6 heads would i still be better off with the reverse split cam or should i with the bigger cam and benefit more going with the bigger cam? i really like those 2 cams and unsure which would suite me best.

decide first exactly which intake and heads you are gonna stick with and get a cam
to suit that package,stock ls1 heads like reverse split,but if your not sure which head
observe the various cam +head dyno graphs to give you some kind of idea of plotting down a power curve to suit your needs.if you insist on fitting a cam first with the stock heads then plan to switch to other heads you will be better off with single pattern
or dual pattern grind that works reasonable on ls1 heads but better with your nominated head,so it saves you in the longterm.
compromise is the order.

Reverse splits tend to favor stock heads, so i've been told. With aftermarket heads i still say stick to single pattern or traditional splits.

At the same time, i am a little skeptical of these reverse splits anyways. I don't see the logic in the exhaust flowing as efficiently as the intake. But at the same time i'm no mechanic, and i'm sure i'll get burned on that statement. That's just my .02

228R
225/229 (Patriot's new cam)
228/232 XER

I ran the 230/224 all last year, its a freakin awesome cam. Just bought the TRac for new setup though... Good Choice you will love it

Its not just the stock head, but the intake as well. The problem is there are lots of great flowing heads out there, but put them under an LS1 intake (like your '98 probably has) and the intake flow drops a considerable amount.

The best application for a reverse-split appears to be a full exhaust (ORY or Duals) vehicle with stock or mild ported heads and LS1 intake, or LS6 intake with stock heads. Much beyond that, and you can get away with less intake duration to make the same power.

The real benefit to a reverse-split is the power potential that is there, without the overlap a traditional split would have. Examples:
As the pattern changes, each cam creates more overlap, and drivability suffers as a result. At least we keep the same LSA and the IVC point reamins the sameso that our power peak is kept in check.

Now look what happens when you spread the LSA to keep the overlap the same:
Now we've kept the same overlap, and therefore very similar drivability. However, in doing so, we've pushed our already late 46* IVC back to 49* ABDC, well past the point where our LS1/LS6 or FAST intake is tuned to peak. Power across the board is going to suffer, and the peak will be rather soft. You can advance the cams to get the IVC back where you want it, but the VE's just work much better with a Reverse-Split cam.

Beyond that, read the ***Cam Guide*** sticky at the top of this forum, and look for these:

That trex cam would be a huge turd down low with stock gears.. Not a very good cam for a daily driven car, it's just not practical.. :)

thanks for the info i have made my decision.......tr230/224 111lsa, as soon as its installed i will post numbers and give it a full in depth review
