Well thats basicly the same cam that i ordered, except mine is on a 112 + 2. Personaly i would go with a 110 straight up, i went with the 112 + 2 becuase my exhuast is a little restrictive so i wanted a cam with a little earlier evo, but if you have a good exhaust i would recomend that cam on a 110 + 0. I'll have some dyno numbers of mine hopefully later next week, went in for a baseline toda, installing the cam this weekend so i'll post my resualts

P.S. Even tho i ordered it as a 227/231 .639/.643 it ended up being a 228.5/232.9 .644/.649 after i doctered it.

What springs are you running, what kind of exhaust? Sorry for the many questions.

My sig gives results for a 223 lsk intake and 228 xer exhaust @ 116 in my ctsv. Idles like it's stock.

Was asking thirdgenls1. I know your setup, and am quite envious of it.

that's pretty awesome. Keeping the idle stock in that is probably a priority in that car. I'm going with a much lower lsa in hopes of raising dynamic compression.

My only worry is with .040 cometics and .030 milled, my compression might be to high. But looking at Patrick G's setup, it should be fine on 93. My machine shop is scared of that high of static compression though.

Any notes on that anyone?

When I did the cam, I put in a 2 piece timing chain cover with the idea to try some different cams. This first cam was just an experiment to see what we could make with a stock sounding cam and still pass the sniffer. This is all on crappy Ca. 91 octane gas, Sam's club 91 to be exact. I would like to see what kind of results Patrick gets, that will most likely be my next cam. I would like to pump up the TQ down low and see if it still carries the peak power. The V is a very easy cam swap, so HURRY UP PATRICK!!!

Mine spec'd out to 224.0/228.6 with .641"/.646" lift and 110.1* LSA. Can't wait to get this thing on the road. Picking up shortblock tomorrow and then I have to order bearings and oil pump and assemble it all again and put it up in the car. Should probably upgrade the clutch at the same time too because I don't see my stock clutch living up to this setup.

This thing is going to be scary to drive. The last month and a half I was driving my car with 7 cyls (so down on power big time), and now I haven't driven it in a week or so since it started a main bearing knock (as expected from the running rough). It'll be another 3 weeks at least I'd expect before I get the car running again. I'm probably going to **** myself the first time I step on the go pedal. This'll be the fastest car I've ever ridden/driven

Oh sorry didnt know the question was directed to me, i'm running comp 921 springs shimed to .050 of coil bind. As for for my exhaust i have long tubes to a 2.5 y-pipe w/cats, to a GMMG exhaust. The thirdgen camaro is a lot different underneath so running long tubes with a y-pipe is a lot more difficult, fitting a 2.5 y-pipe under there was tough enough, plus theres only one company out right now that makes LT's/y-pipe and thats stainless works.

I got it baselined the other day and even with my shitty exhaust and a 4.10 gear it put down 335 hp 346 tq. so not to bad with just exhuast, i was happy.

Any ways i'm anxious to see how Patricks car responds and i'll make sure to let you guys know how mine comes out when i go for the dyno tune.

Justin

oh yea i'm installing the cam as we speak so hope to have it done with in the weekend.

Very cool post guys.

I will have to go through the top end of the motor and this would be the perfect time to replace my old school cam. I am definitely leaning towards your cam Patrick maybe even the larger cam you spec'ed out for a little more top end power. What specs would need to change if you were to run a 150-250 shot of nitrous.

Thanks

Absolutely nothing. You always choose your cam around your NA goals unless you plan on running a LOT of nitrous. A LOT of nitrous in my book would be considered 300 shot or more.

Spinmonster

I think there is a lot of misinformation running around about what makes a good nitrous cam. The same issues as any forced induction scene: no overlap and maybe a bit more bias on the exhaust side. People see 110lsa and they think 'bad FI cam'. They see some huge duration and 115lsa and thats good then. I have yet to see any cam that is streetable not make a 100hp with a 100 shot.

RunNE1

Yes, I was always told to go with a higher LSA for N20 and also for the fact that my car was an automatic(LSA~114).

Spinmonster

Its incorrect information because a cam with 114 lsa can have more overlap than a cam on a 110lsa. The overlap is also a function of duration.

An auto will idle better at lower rpm's with 224/228 on a 110lsa with a than with a 236/240 114. The second cam has more overlap. Same as nitrous or other FI applications; the one with more overap bleeds off the boost.

PREDATOR-Z

It is not only a function of overlap, but mainly of exhaust valve events.
I have a 232/234 113+0. It is slightly exhaust biased so it performs well under juice.

So does every cam I've see that is streetable. Like I've said, I have yet to see a cam that doesn't produce a 100hp from a 100 shot. Even a reverse split can do well on a 100 shot. The cam you run would suffer the same midrange issues as compared to the LSK lobed 224 cam that Pattrick Guerra is proposing and for the same reasons. A 232/234 cam is still softer than the one he installed and on any FI format would still be softer in the same areas for the same reasons. Patrick's LSK cam has 2 degrees less overlap at .006 lift from a 110lsa compared to your 113 (assuming that the initial ramp rate is reasonably the same as an XER grind--if it is 50 at .006 then his cam is 54 at .006). Tighter LSA's dont nec make a cam bad for Nitrous is all I was saying....but then you knew that already.

Overlap is a funtion of exhaust valve duration (and intake) so my original statement is correct and I don't understand why you state the above as if exhaust valve events and overlap are separate from each other. Overlap is not mainly exhaust duration/events...it is equally effected by intake valve changes and LSA. It is the number of degrees they overlap;one degree on intake changes it the same as one degree on the exhaust side....play with it on this site. An interesting thing to note while you play with it....as you advance or retard a given cam the overlap doesn't change but the intake valve closes sooner boosting dynamic compression. When you advance a cam, the number of degrees you advance or retard adds and subtracts fromt he E/I lobes the same amount. If it were mainly exhaust valve events then it would change as advance changes.

Read again, I'm not dissagreing with you at all. I said Meaning that for a tight LSA/higher overlap cam to still perfom well under juice, it can do so if the IVO/EVC events are more exhaust biased relative to TDC.
You're absolutely right about the TRQR V2 being sluggish and shy of trq (not what we expect from the name). I found that from my track time when I switched from my 224/220 and only bettered my times by .15 sec (both cams tuned) but identical setups. The TRQR performed better under juice though, netting me ~.4 sec better times with same amount of shot.
This is why I'm putting it back in a 6.0, this time with ~ 11.45 SCR and 8.58 DCR. I think its VEs will benefit the larger cube motor better. I might advance it 2* to make even more trq earlier, making it even more exhaust biased for the juice.
If I'm wrong, well i'll post about it and change that sucker out.

Spinmonster

I understand what you meant now. On the first read it looked like you meant that overlap was mainly from exhaust vale events but you were talking about nitrus applications.

C'mon you could have worded that better.

That cam you have is from Texas speed? What did you put down with it dyno numbers?

PREDATOR-Z

Yeah, that is what she always says.
I meant "I love you very much" and she heard "Man those are some nice headlights"

When I got it, I knew this wasn't the best, It gave me 7.90 DCR with 10.70 SCR. But that is the biggest i could fit with my 2.04/1.575 ported 5.3s without flycutting. But knew the juice will wake it up.
I managed 429 rwhp 387 rwtq (get this, that was only about 6 Hp and 4rwtq, more than my 224 cam )
