You said it. PErformance is about the same so why not save $50 and buy from LS1 Speed.

 

Since your local to me, Why don't you call Deema Elgin of Elgin Cams in Redwood city and see what he has to say about a small shop that builds cams.. Ask him what he thinks of off the shelf cams from comp, or even their custom grinds. He doesn't design custom cams for NHRA prostreet for nothing. He also doesn't come up with his own cams that do wonders. TR is in a sense like him doing R&D to make things go very fast. Both make their own lobes and both do a great job.

havent you been saying that TR DIDN'T come up with their own lobes and they are just using the Comp XE lobe?

 

looks like you were the one who came out swinging first.

 

Bowtieman4life, I've never ordered from TR but I have from LS1speed so I will agree with you that LS1speed has good service. But you are the one that looked like a jerk in this thread, not TR.

Why do you have a problem believing what they say? Its not like you have personal experience with their cam. TR says their cam is a little different and unless you have proof otherwise, then most people here don't have any reason to doubt them as they have a good reputation with people of this board. Now if you just wanted to argue that the differences weren't worth $50, then you would have made a valid point. But instead you implied that they were lying.

 

LilSS,
Do you have your TR cam yet?
If so, PM or E-mail me the #'s on the back of the camshaft. What you'll see is either a Comp part # or the lobes that are used & the LSA the lobes are on. Send me the info on the back of your TR cam & I will tell you for sure what lobes they used for your cam. That ought to put this thread to rest.

 

Guys... this is ridiculous! I just needed a simple answer. It kinda sounds like no one knows the difference. Does anyone have a good, honest list of the differences between the Comp and the TR 224 cams? I'm kinda looking for someone from Thunder Racing to answer because who would know better than the people who make them. Thanks.

 

I believe they responded already somewhere in this thread or the other one. They said the TR224 has a ramp rate of almost that of a Comp XER, but with less lift.

 

Alright this is it. This post is getting old. You stated that TR has no reason to stretch the truth. Well think about it. If they admit that they use Comp XE lobes on there TR224, no one will pay the extra $50 to buy there cam. They have to maintain there position regardless of the truth. Oh, and you take this post anyway you want. If I caome across as a jerk, oh well. I call a spade a spade.

As for little SIS, I can't beleive you would even consider comparing TR with Elgin. Elgin truly creates cams and has several competitive car running them. How many TR cams are being used in NHRA. Dude, please! Let's get real. Apples and apples ok SIS.

 

I'll agree 100%. I've had both Comp grinds and TR grinds. The TR224 lobe has 274* advertised duration, which makes it a faster lobe than the XE224. The difference in lift between the two is negligible. The TR224 should provide a better idle and better throttle response due to less overlap at .006" and more max power due to the faster lobes. I have cam doctor reports that show TR lobes are faster than Comp XE...but its not my place to spread the data all over. I got my TR220 cam over an XE220 because I wanted to make sure that it idled well. I'm sure an XE would have still idled well though. As far as an XE-R 224 cam...it has 273 deg advertised duration at .006" and has more lift under the curve than a TR224. I liked my TR220 cam, but I got my Comp grind for a great deal from a local guy so thats why I have it now. If I had to personally rate the lobes as far as power it would be like this from low to high-XE,TR,XE-R. Its kind of nice to have a choice in aggressiveness between the two comp lobes. Good luck

P.S. These anti-TR people were not around when the TR cams first came out. Thunder Racing raised the bar on cams and were the first ones with aggressive ramp rates and to push cams with more than 221* duration while many shops said it wasn't going to offer any benefits. MTI offered the B1 and T1 for a year or so and then TR came out with their grinds and were consistently putting out better numbers. IIRC, the XE-R lobes were not even out when TR started their grinds.

 

Now who's getting all huffy puffy with the name calling.. Obviously your taking this personal when I'm only trying to state facts for you. I'm quoting your own words to try and show you the light but obviously your not seeing it.

You just come accross hypocritical. You state things, I bring up good examples to you just let you see what you are saying is not true. But none of it is sticking for you.

 

I am out!

 

OK here it is, earlier in this same thread:
Geoff:

 

OK, I got your PM so I had to check and see what you said. Show me the light? Are you Jesus, Budda or Mohammed. WHat's up with that? Also, you have not used a single good example to show me I was wrong and you have not used my word correctly. You compared a famous cam designer with a resell shop.

Bowtie, I will show you some of the comments that I am talking about. I'll show you where you look dumb for saying something with no merrit behind it..

I would always trust Comp over a small shop.

How anyone could beleive that a small shop could come up with better lobes than Comp is beyond me.

My example was Elgin Cams.. They are a small shop. They are not a huge corporation like Comp Cams. Who puts out a better product?




Comp makes TR's Cams.

As for TR being a better product than Comp, remember who actually makes the cams.

Thunder might very well be a great shop but there cams are made by Comp.

Call Comp and see who makes their cams.


Have you taken your own advice and called comp? Or are you taking someone elses word for it that TR uses their lobes. If you did speak to comp, who was it?




Prove that the lobes are different than the XE high lift and prove that they are larger than the XE-R lobes.

Have you put all 3 / 224 cams in question on a cam doctor? Where are your “facts” coming from?




Ferocity,
I apologize some of us have hi-jacked your thread. See the comments from Geoff, Angie and Paul @ Thunder.. These are all people from Thunder that will have real info on their cams.

 

The back of Thunder Racing cams are stamped with the part number of the cam, and the serial number. The part number will be something like TR224-114. The serial number will be 4 numbers/letters. I will be happy to post a picture of the back of one of our cams tomorrow.

 

THANK YOU!

Our cams were out close to a year before Comp released the XE /XER lobes.

Angie

 

I can attest to that. Just installed a TR-224 cam in a friends car this past weekend.

 

Bowtieman4life - Why don't you come up with SOLID proof before you accuse somebody of lying? Then they might not say you look like a jerk spreading false info.
