Default Thoughts on my a new cam....

I have been running some numbers and here is what I am thinking about getting ground.

226/226 .595/.595 110 or 108 lsa with 2 degrees

Any thoughts? My idea is the LSA will make the combo make some sick horsepower.

Do you have notched pistons? Dunno if that cam is going to clear.

After all the cams people have tried on here (I'm on my 8th!) I dont know why you don't pick one thats proven so you dont have to worry if you chose right later. The biggest numbers I've seen on here have been from the 230/224 cam on a 111lsa.

If you are basing your info off that dyno simulation program, you should probably know that it never seemed to match up to well with real life results on an LS1. Other motors, maybe its great. the LS1 it has issues modeling.

That cam may be close.

I just clayed a set of GTP S2+ head that were milled (not sure how much) and set up for 11.4:1 compression with a 223/.591/112 cam and on the exhaust side I had 76-80 thousandths clearance. This cam is a pretty fast ramp rate too.

So depedning on your max RPM you could be very close.

I am plotting them on a dyno simulation but check this out. I started with a 230/230 .578 114lsa and compared that to a TR230 and the graph shows that the TR230 will have more power above 5500 and about the same if not slightly more torque. This is basically what the real world found out with this cam. I tweaked the numbers and ended up with a 226/226 110 lsa with 2 degrees and it netted slightly better numbers than the TR230. Honestly not much is different than a TR230 duration is within 4 degrees on each lobe, LSA is slightly tighter, overlap is within 5 degrees and lift was the same. I definitely dont think that this cam will be a step back maybe a baby step forward.

Why 2 degrees and not 4 degrees built in? I like the specs.. My old 226 XE-R lsa 112 cam with 4 degrees peaked at 6k to 6100rpm.. Things that I have learned by spending crazy loot.. Cars with the B1/T1/TR224/C1/C2 and similar have ran crazy times.. All thoses cams have dyno'd crazy #'s with the right supporting hardware. The PIG CAM and Futral Motorsports 226 were the first cam that I know of with similar specs to what you are looking at.. Both of those ran awesome and produced awesome #'s on the dyno and at the track. Remember, we have a crazy # of members, but mostly the ones that are happy with their setups tell you what is going on.. Not everyone is on the up and up.. Some lie about race weights, what tires they were running, flow #'s, lie about thier dyno's, what fuel they run, etc.. DO NOT BELIEVE EVERYTHING YOU READ HERE.. I would go to an event and check out most of the cars in person.. If you can watch them weigh in, do it. Look around and ask questions.. See it for yourself.. I even wonder if some of the people that post even have a car.. <img border="0" title="" alt="[Smile]" src="gr_stretch.gif" /> Basically, get first hand knowledge. Hearsay can cost you a lot of money..

Maybe I'll step it down to .580. Thats what I am basically running with my current cam. I am trying to test lobe seperation.

Did you have all the TR230's on your sim at 0 advance? Not 4 degrees.. Jason99ta runs his cam at 0 advance. I think Justin and Chris do as well secondary to the Tq difference between the TR230 and the TR224.. The TR224 from what I was told is on a plus 4..

I have all of the specs from the cam cards. I think that the 2 cams should perform almost exactly the same. The differences in the duration isn't going to make that big of a difference.

I think with 110 or 108 LSA I wouldnt grind ANY advance into the cam at all.
It'll peak pretty early.

Why does he not want his setup to peak early? When did you change cams Chris..?

112 LSA... I'd run 224 thru 228 duration

110 LSA... I'd run 230 thru 240 duration

108 LSA... I would not run this duration without the support of it working in another car

If the cam was say 232/232//110 I'd go straight up, and then i'd advance it if the dyno #'s supported it.

I ran a 236/240//111 cam a few years ago, and I would go about it the same way... straight up or maybe +2

You cannot say +4 is the bomb because you need to support that.

Heck my 242/242//112 is +4 and I think I'm going to retard it -2 if track data supports it... because right now it's peaking too early.

Default Re: Thoughts on my a new cam....

Once again I have to defend my beliefs.. Respond if you have run the 226 XE-R with 4 degrees of advance.. Wow!! Thats me.. Respond if you lost 30rwtq and 20rwhp below 5000rpm by changing cams.. Wow!! Thats me.. I went from 226 XE-R with 4 degrees of advance to 232/226 XE-R with no advance.. Hmmm.. According to the REVERSE SPLIT THEORY.. You should lose no tq or hp increasing the intake. So that tells me that the only thing that changed was the advance built into the cam.. Both Chris and Justin loss tq by going to 0 advance. Hmmm.. I have decided I am going to advance my cam 4 degrees.. I have to give credit where it is due. Fireball had mentioned the point about my decision to go with 0 advance instead of 4 degrees advance like I had on the 226 XE-R cam and he said that is most likely where my down low power went.. I have asked others and they all agreed.. Yes, going with plus 4 might bring my power band down a little, but the peak should remain the same or be a little higher.. The only reason I said that plus 4 was the bomb is because Phil and I have been sharing emails and from what he has told me I personally think it would be best. Should I be giving out advice? Maybe not.. I know some others that have commented on this post that should fix their own issues as well before they give out advice.. I see no perfect combos here..

Default Re: Thoughts on my a new cam....

After which cam swap Chris I did not use ls1edit going from 226 XE-R to 232/226 XE-R, but Chris and Justin did.. They still lost tq.. I am running 29 degrees of timing now at WOT. How much more do you think I need? My A/F is not that bad. It's just rich below 4krpm.. Real rich.. Playing with the maft leveled the A/F to 13.3 post 4krpm, but my ltrims were not locked at zero at WOT.. They were on plus 8. At part throttle they were at plus 13. A/F is not the tell all.. Post putting the T1 cam in my A/F was 13.1 and I dyno'd 372rwhp.. Post Ed Wright tuning my A/F was 13.1 and I dyno'd 390rwhp.. I have since played with the maft some more, but I have not been to the dyno.. I have the ltrims staying in the negative and locked on zero at WOT,.. My O2's are still 930's to 940's. I will let someone else play with that.. Back to Phil's cam advice..

Chris, my example is not meaningless. Jason99ta swapped from the TR224, TR227/224 and then TR230/224 all on the same program he had for the TR224.. He picked up horsepower on each cam.. I am trying to keep this civil.. Saying that my example is meaningless will only cause you or your peers to lock this thread..

LOL!!! First of all.. What vendors heads..? Second.. There is no real criteria on what really works for the reverse split.. Geoff on a previous post mentioned as long as the heads flow characteristics are similar to stock then the reverse split will work.. Hmmm. My heads meet that criteria.. I am not exhaust limited when I open my cutout so that excuse is gone.. Now that ls1edit is out.. All other previous tuning is out the window and therefore was so far inferior.. Not!!! The only thing ls1edit did was give others the ability to put a dent in Fastchips, etc., wallet. Now that we have changed this post to Vince setup. Lets talk about YOURS!! What are your #'s.. Not the rush to the track when the cold front rolled in. I mean your real #'s Chris.. Why dont you post your b4 and after dyno sheets instead of criticizing others.. Oh, my bad.. Dyno #'s do not mean anything. Just track times when the cold front rolls in.. Oh yeah, ET Drags are not ET Streets in the U.S. <img border="0" title="" alt="[Smile]" src="gr_stretch.gif" /> P.S. This is not a bash... <img border="0" title="" alt="[Big Grin]" src="gr_grin.gif" />

"When the cold front rolls in"

I have run mid 11's all summer and now low 11's with the new cam change, new clutch and tuning <img border="0" title="" alt="[Smile]" src="gr_stretch.gif" />

Raceweight 3400 pounds
11.30 Best ET
122.60 Best mph
Havent raced in DA below ~650 feet <img border="0" title="" alt="[Smile]" src="gr_stretch.gif" />
and yes my 1.58 sixty was on ET streets (Want me to take a picture for you LOL <img border="0" title="" alt="[Big Grin]" src="gr_grin.gif" /> )

What are you going to say when I run 10's@123-124mph+ in the spring with 42XRWHP and 41X RWTQ from my S1 ARE heads and single pattern hydraulic cam? LOL <img border="0" title="" alt="[Big Grin]" src="gr_grin.gif" />
cheers,
Chris

Phil.. Sorry for stealing your thread.. Chris I was just having fun man.. We all know your car is fast.. You went from FI to NA and both setups were fast.. I am a little under the weather with some kind of bug and my girlfriend is not around to gripe at.. <img border="0" title="" alt="[Smile]" src="gr_stretch.gif" /> So I come to my friends to share in my happiness.. <img border="0" title="" alt="[Big Grin]" src="gr_grin.gif" /> One day I will do the necessary weight reduction, get a 12 bolt and see what my car can really do. Right now I am enjoying a nice full interior low 12 sec car on regular street tires.. Phil I can only tell you what works for me. Yes tuning is a big part of it.. The closest ls1edit tuner is 10 hours away.. <img border="0" title="" alt="[Sad]" src="gr_sad.gif" /> So my trip up north will be well worth it..

Vince,
hehe thats cool man <img border="0" title="" alt="[Smile]" src="gr_stretch.gif" /> All in good fun!

Phil,

What Heads are you going with or is this cam on stock heads?
you cant really go wrong with a TR or XE-R 224/224 cam for good driveability and decent idle. I wouldnt recommend a 108-110 LSA with those low duration numbers thats all. <img border="0" title="" alt="[Smile]" src="gr_stretch.gif" />
Cheers,
Chris

I contemplated doing a 108 LSA cam in my 422ci but could not find data to support it... and a 108 will idle pretty crummy so I didn't want to suffer.
