if you had 5.3 heads would you take a reverse split overa traditional/single pattern cam

I think there might be something worthwhile about a XE-R intake and TR like exhaust. The exhaust doesn't really have to have an uber fast ramp. Might save a little wear and tear on the valve train.

As for the Reverse-Split vs Split debate, most of the time I think a nice single pattern is a good choice for most folks. The Reverse-Split always seems like a crutch to work around an intake that won't flow as much as you'd like.

I think a 232/228 Reverse Split w/LSK (or faster) intake & TR exhaust might be interesting.

I wonder if anyone has tested any sort of asymetrical cam lobe. Say some sort of LSK (or faster) like opening ramp and an gentle XE close on the intake valve.

when pred listed the tr230,I knew it would not be long for you to comment on this

it's a proven cam, time and time again.

Ive got a whole list of cams I'm debating on swapping to.I am partial to thunder though.I may spray still not sure.I would like more N/A. I think with a well thought out cam to go with my TSp 5.3 heads/ported fast90/90 and switch to duals and add a pulley I could see 440 in a A4.I just dont want a huge cam that I have to spin real high with no bottom end grunt,and driveability issues. I think its doable.Hell I know a guy with a stalled A4 that puts down 399.2rwhp cam only,not a big cam either

so pred
Reverse split cam or traditional single pattern

Ok, just read all of this. I like this topic although as mentioned it isn't anything new.

PREDATOR-Z

It depends on the overall combo and goals for the car as a whole.
As I mentionned before in this thread, reverse splits are better IMO in cam only applications where the user doesn't want to buy a boatload of supporting mods.
The TR230/224 is a perfect exemple although I would fine tune that one myself to make it less peaky.

As for the comment that reverse is just a crutch for poor intake, well welcome to LSx tech, all of our intakes on the market are a crutch (unless you custom make one).
What is the point of having 45>50* IVC on a big cam (346 cid) if the intake makes it peak at 6300 rpm? Or having 48+* IVO and loosing most of you midrange trq?
It has been discussed and proven many times that for most street setups, power under the curve is what counts, there is where a reverse excells

Take a 232/234 112LSA and a 232/230 112LSA (the reverse will have better undercurve if VEs are tailored right). Having the same intake they in theory sould make the same power. But the question is: " Where in the band is that power? and is it beneficial for your application?"

As for would I go Reverse or traditional with a set of 5.3L, it depends what powerband do I want to achieve. Do I just want to look at dyno peak? then traditional. Do I want better undercurve? Then reverse. This comment is relative to SCR, DCR and how much mods I have of course.

Really interested since I also have an A4 with the same goals in mind. I really like the tr230/224 and not sure if it would be really worth the extra cash adding tsp 2.5's and fast 90/90. I also would like to top out around 6400, I would be all over this combo If I knew it would make 440rwhp. What cam is your buddy running making 400rwhp in an A4?

I was all set to get a 231/237 .589 .595 112 lsa cam, but after talking to Larry @ Speed Inc. and telling him my car is just a summertime/weekend cruiser, wanted to stay N/A, and I still wanted to maintain somewhat stock drivibility, he suggested their reverse split 228/222 .588 .581 114 +5 cam. This cam is perfect in my book, great drivibility, and made nice power, it made 394rwhp. This cam will also work great with my future mods, some TEA Stage 1.5 5.3L heads, and Fast 90/90 set up.

Hey Jasson I really like your set up, your heads are the 5.3L stage 1.5 from TES correct? I am really leaning towards TSP 2.5's with either the TR230/224 or X1. I like the results from them, do you think this combo would be close to yours? I would like to go the fast 90/90 setup, but not sure right off the bat, unles if would really be worth it. If I go the traditional route I think I am going to go with the tourquer 2, but really like those RS cams! I think it would work with my A4 alot better too for the street. I have MTI 78tb, 3600 yank, 3.42's, full exhaust, susupension and 315 mickeys. Thanks

I still say don't bother, you aren't going to gain that much. Just get more supporting mods like the electric water pump.

Hey Jasson sweet set-up man, those TEA 1.5's are they the ls6 or 5.3's? Thanks

Mine made 399.2 rwhp with stock untouched heads and crappy mac mid headers, the info is here: https://ls1tech.com/forums/dynamometer-results-comparisons/476349-tr230-224-a4-dyno.html

how would the older patriot performance 232/230 perform with full bolt on (ls6 intake), stock headed ?

PREDATOR-Z

It would perform well with different valve events.
I would put it on a 111 or 110 LSA

Not worth it because the cam you have makes decent power and your car is so light.
