Hey everyone. I thought I had decided on the Torquer, but all this talk about the 233/239 and the numbers I've seen it put down thus far have swayed me into thinking about it. Given that they're both the same price, which would be better for me? I'm running stock heads, SLP cold air, SLP lid, LS6 intake, ASP pulley, Pacesetter LT's, 2.5" x-pipe w/ Moroso Spiralflows, and a TCI 3500 stall (soon to be installed), and my car is an A4. Given that I want to keep my stock heads for a while, which cam would be best for a car that is street driven 90% of the time, with limited track time? I think the 233/239 would be better with nitrous, but are there any other advantages over the Torquer? I'm looking for solid midrange torque and power, as well as some violent top end. Thanks.

 

I'm not an expert on either cam, but I have heard that LS1's do like a split pattern cam.

 

Cool, did not know that. Thanks. BTW, idle is not a big concern for me.

 

ahh the pefect question to ask!!! im in the same situation.. except i have a truck to drive 1/2 the time.. i only have a 3000 stall but am ugrading to 3500-3800 when i do the cam.. my big issue is i spray a 150 shot about 1 outta every 4 runs.. n/a times mean just as much as nitrous times do

anyways good thread.

 

The 233/239 will allow for the exaust valve to hang open a little longer, thus compensating for restrictions in your exaust path. In this case, a stock exaust port. It's my personal opinion that you will do better with the 233/239.

 

yea idle isn't a concern, tho id imagine the streetability and everything else would be close b/t these cams, but which one is going to make more power n/a, we know the split is better for nitrous, but will that cam give any lowend tq up to the tq'er.

both cams sound nasty tho!

 

hmm so that means it will dyno better on and off the nitrous probably... since it stays open longer thats good for n2o right?

 

Basically, the exaust valve hanging open longer creates more overlap. LS-1's tend to do better with more overlap, plus nitrous loves overlap. The cam should do better for both N/A and spray.

 

Anyone know where the 233/239 peaks with stock heads?

 

Not too sure offhand, however there is at least one good dyno graph from TSP of that cam and I want to say torque peaks around 4500, and horsepower in the low 6000's. Since I'm keeping stock heads or at least mildly worked 5.3's in the future, perhaps the 233/239 would fare a little bit better in the context of my setup. More opinions/advice please. You guys are invaluable. Thank you as always. Have a nice night.

Well, the 233/239 is based off the 231/237, which is a Lunati grind. The Torquer is a Comp XER grind. With the more aggressive lobes of the Torquer, one would assume that you should make more midrange power. However, the graphs posted by TSP show pretty much the same TQ curve. But, I don't have any detailed info of how the two cars were setup for those runs. I think we need more third-party dyno runs to accurately evaluate the differences between these two cams. Given common knowledge, I would say that the Torquer SHOULD make more midrange power than the 233/239 in the same setup.

 

But if the torquer is using a XER grinfd, and the 233/239 is using a lunati grind, is the 233/239 going to be easier on the valvertain than the torquer.....assuming that the torquer's XER lobes are much more aggressive, and beat on the valvetrain more than the soft lobes of the "lunati 231/237 based" 233/239

 

Both the Torquer and 233/239 use the XE-R lobes.

 

Correct. TSP upgraded the lobes on the 223/239 to a XE-R type lobe. I don't think it is ground by comp, but the numbers are about the same. The power should be very similar if not identical to a G5X2.

 

hmm nice... what stall would be good for the 233/239, and keep in mind im spraying.. also ill prolly get 3.73s think that will work with my cam? sry to post here i just wnat it all at once ya kno

 

If it's anything like the G5X2, that wouldn't be bad at all. I'm still wondering, since the graphs are so damn similar, what is the significant difference between these two... I'm leaning towards the 233/239 because it's a bigger cam and I figure if I do it once, I'll do it right. I think a smaller cam woulf honestly be a waste of time given how much springs and a tune would cost, and given my goals in terms of horsepower and track times, a large cam would be advantageous in my situation. I think a 3500 stall and the 233/239, with full bolt-ons and true duals would be a badass setup. Plus, that little lobe wouldn't sound so bad sitting at a stoplight. Thanks everyone.

Nope. The 233/239 is not an XER lobe design. It is a Lunati grind, based off the 231/237 as stated before. The lobes ARE more aggressive than the 231/237, but not up to XER specs. Or so I was told by TSP.

 

UPDATE: I e-mailed Jason over @ TSP, asking which of the two would be a better choice in my situation and he recommend the 233/239 because it seems to put down more power that the Torquer and because it's easily streetable. So, I believe my decision is made there. Although I did find a KILLER deal on a GMPP ASA cam, but who knows. Thanks everyone. Any more input? Keep it coming.

yeap, think ill be doing the 233/239, from the few other threads i was able to search it did look streetable with a great tq curve.

 

jason likes that cam.

he reccommended the same cam to me....

hmmmmmmmmmm

i have been pullin hair over the f13, torquer, or the 233/239.

think i am leanin toward the 233/239
