I just put in my TR224 114LSA and it sounds great! Ive never heard Comps so i couldnt really compare the 2. Im really happy with my TR though.

 

Bowtie Man,

You are really starting to look like a jerk deliberately spreading misinformation about our cams. You are so convinced you are right about our camshafts, have you ever actually measured one? Do you own a Cam Pro Plus? I didn't think so.

About the only 2 points our cams have in common with the Comp XE lobe is the lift and duration @.050 lift. They are pretty much different everywhere else. Also our 224 lobe is much closer in acceleration, if not more, than the XE-R lobe, with less lift.

 

Oh now the attitude is starting and the name calling. You must be one of those internet tough guys. Prove that the lobes are different than the XE high lift and prove that they are larger than the XE-R lobes. Look at the post before mine. Are the lobes on the TR224 larger than the XE-R lobes? No! They are not. If you are so sure of your cam, I will bet you any amount of money that the TR224 lobe has less duration than a at 200, 300 and 400 lift compared to your Comp 224 using XE-R lobes.

 

I'd like to see someone scan a 'Cam Pro' printout of their TR cam. With .006, .050, & .200 specs. Lets see just how different these lobes are.

Please take into acount that 2 identical cams from any company will NOT spec out the same. They are ground when ordered...not all at the same time...nor by the same tech. Also remember that minor differences like .00x of an inch or 1 degree out on a 720 degrees on a 2.2 inch circle is VERY minute & easily happens when grinding the cams.

 

Personally I'd go Thunder over Comp. You won’t believe the great service Thunder offers. They have done me right, and their grinds are proven performers. These folks know LS1's and what makes them perform. TR all the way.

Check this out. Now there's a package to copy.

98TAauto, I agree with you! I doubt there is much of a performance difference between any of the 224 cams that are available; everybody's on to the secret: fast ramps. I even saw a '99 SS with a custom Comp 224 that had only a 0.533 lift and it dynoed over 400 rwhp!

But I still like Thunder because of the service and support. For example, pushrods normally come in 100 thou increments, so you either get some that are too long or too short. My kit from TR came with hardened pushrods only 20 or 30 thou longer than stock, perfect to make up for the smaller base circle and get the lifter preload right on. As a result, I have a very quiet running valvetrain; nearly stock with no "sewing-machine" sound.

 

I have dealt with LS1 speed and they have excellent service as well. They sell Comp custom and off the shelf cams for $379. Save $50 and still get great service. That's a tough one. Personally I had some personal requirements that I wanted out of my cam so I had 93PONY spec it and I ordered it from LS1 Speed and I will smoke a TR220 and a TR224 cam only car.

Don't make this a service issue. I am talking cam performance not customer service. Thunder might very well be a great shop but there cams are made by Comp.

 

Hey Bowtie.. I'll make you a deal. When my TR224 goes in, I line up with you at Sac.. Hows that sound? Looser buys lunch ok?

Pretty big assumption of beeting any TR224 cam out there. Have you even put the car down the track yet or are you still looking at your dyno numbers on a lean motor?

 

YEAH BABY! Its on! N/A cam only cars right!

 

Of course.. I remember you mentioning 394hp/377tq with 13.8-1 AF and

1. Custom 93PONY cam 220/220
2. Asp pulley
3. 916's no titanium retainers(they sent me the wrong ones)
4. LS6 intake
5. cheap deck lid
6. Stock roller rockers (yella Terras waiting for install)
7. No tuning
8. Jet Hot headers and off road Y (weak Y design)
9. Magnaflow catback

But yet no track info.. Mind you, I only made 337hp/342tq with out the cam.. I have a pulley to install, and the tr224 cam.. Once that gets done I'll be dyno tuning with edit and I'll be more than happy to make a pass with ya.. By the way, I think GR8WHITE from our board ran an 11.7x with the TR224 cam in second gear cause it did not shift.. Have you made an 11.7x pass?

 

The XE-R lobe has at least .581 lift, the TR cam has ~.563, this proves the TR lobe isn't an XE-R lobe. The TR lobe is very similar but not exactly the same.


One might be able to get very very close to a TR cam by asking Comp to make a "master" with an XE-R spec'd lobe but with only ~.566 lift. The "master" will cost ~$500 and they you can order your cam for another ~$400 and have cam that's very close to a TR cam. Of course you'll need to check what Comp sent you on a cam doctor otherwise you won't know if Comp actually got your specs right. You'll also need a profile of an XE-R and the TR to compare against. Several of the guys on CAM HELP at Comp are total idoits. I was told it wasn't possible to fit a ~220 degree cam in an LS1 safely. Odds are good the reps will fight you every step of the way on going custom because they won't want to fool with it. I learned this the hard way trying to discuss a small reverse split 224/220 XE-R cam with the Cam Help clowns.

Or you could save ~$500 and just get the TR cam.

 

It's like this as I understand it.

XE is less aggressive ramp rate than either the TR or the XE-R lobe

XE-R and TR are almost equal in ramp rate. The XE-R is a hair more aggressive.

The only reason an XE-R can flow a hair more than a TR is due to the extra lift giving the XE-R ~1-2 percent more area under the curve.

 

I've seen the profiles of the lobes overlayed from a cam doctor. My 224 XE-R vs the TR-224 - they are very very close in ramp rate only the extra lift gives the XE-R a tiny overall edge. The XE-R with the extra lift is harder on the springs etc so it's not a free ride with the XE-R.

 

Compare the XE high lift and the TR cam and you will see some oddly similar or identical lobes. The XE-R not only has a higher lift. It also has faster ramps. Compare the XE-R lobe at .200 -.400 compared to a TR or XE lobe and you will see that the XE-R has a faster ramp rate.

 

I made the numbers in my sig w/ the TR224 and stock LS6 heads through a 3500 stall unlocked! The TR224 speaks for itself.

 

I put a TR224 in mine and I'm happy... I spent a ton of cash on my car ... it was only 50 bux more... lobes are more aggressive than the 563 Comp 224 cam, but it's not as much lift as the 581 cam (which is what I wanted... while the car is no longer a daily driver, I don't want to replace the valve springs yearly)

I'm very happy w/my TR224 cam and I supported a shop that sponsors this board and developed their own spec cam...

And Bowtieman... you really do sound like an *** in this thread... like you have a vendetta against thunder.. you could have presented your arguments in a MUCH better way...

 

If you look at he XE-high lift & the XE-R lobes you will notice a few things:
Given a 224 lobe...
The XE-high lift will have ~4 degrees more duration at .006 then the XE-R.
At .050 both will measure the same.
At .200 the XE-R will measure ~3 degrees larger then the XE-High lift.
When one looks at one specific lift point there may not appear to be much difference....but given the entire lobe there is. 3 degrees at .200 lobe lift is huge. As is 4 degrees at .006. Basically the XE-R 224 lobe is equivilent to the XE-high lift 220 lobe (both measure exactly the same at .006 & will therefore have similar idle qualities), yet the XE-R lobe has 7 degrees more duration at .200. So, the XE-R 220 lobe will have the idle qualities of the XE-high lift 216 lobe, yet perform like the 224 XE-high lift lobe. This is without taking VE's into account. Basically the XE-R lobe is FAR more aggressive.
TR's lobes *closely* resemble the XE-high lift lobes.
Peak lift is a by-product of ramprate & total duration. So, given a .006 duration & a specific lift, it's not hard to determine the ramprate of a lobe. Especially when give the .050, & .200 duration #'s.

 

You also have significantly better heads. Compare apples and apples.

 

I am not trying to sound like a ***. If you recall it was one of the TR guys that called me a jerk. I have yet to use profanity. As for my point of view, its mine and I can believe what I want. If you want a TR cam, go for it. I was just trying to help someone save $50. If my input is not appreciated then don't read my post. How anyone could beleive that a small shop could come up with better lobes than Comp is beyond me. To each there own. Just remember that several shops out there use Comp lobes.

Before you buy a cam talk to the guy selling it to you and ask as many questions as you can. Do your research and compare.
