Which is better for a basically stock engine? Whats the difference between the 230/224 and the 227/224 cam? is the 227 more streetable.How do they compare to MTI's T1. I have an M6. This car isn't just a drag racer. I do some road racing. How much HP do each of these make roughly. I'm looking for about 30-40 horsepower. People with any of these cams please respond.

I had the T1 and it is similar to the TR224. From what I have heard all the cams are streetable and should dyno within 10 to 15rwhp of each other. TR230/224 maintains the lowend tq of the TR224. The TR227/224 is milder than the TR230 and is preferred by some. It also depends on your gearing. You mentioned road racing. I would think the TR224 would be best secondary to the gears you should be running with road racing. Plus you would come out of a turn nice and the idle quality of the TR224 is better than the TR230. That is my take on all the information that Thunder Racing has provided..

From what I remember, the TR230 is superior in top-end power (6K and above I believe) to the TR224. I haven't heard anything about the TR227, what LSA is it?

I forgot to mention that I'm running 4.10 gears. What horsepower can I expect with these 3 cams? I have a ported TB and MAF, SLP lid, gutted cats,and a Supersucker. Right now I'm at 332RWHP/352RWTQ.

I have had all three of those cams in my car. All three are excellent cams.

The 224/224 and the 227/224 drove nearly identical around town. The 230/224 did have a harsher idle and driveability did suffer slightly. Considering how well the 224 cam drove, it really wasn't a big deal to me.

Here are the dyno graphs comparing the cams:

224/224 114lsa vs 227/224 114lsa

230/224 111lsa vs 227/224 114lsa

230/224 111lsa vs 224/224 114lsa

If you have any more detailed questions, just let me know.

Jason, thanks for the graphs. You work there right? I looked on thunder racings board at the cams. I think I'm interested most in the 224/224 112 LSA then the 227/224 114 LSA. In the graph for the 224/224 LSA 112 its making better than 390hp. Was this on a basically stock car? With my mods what kind of horsepower can I expect with this cam? What is the rocker arm ratio in the stock LS1? Can I just use the cam package TR advertizes to upgrade the valvetrain? I've put a lot of cams in Chevy bigblocks and smallblocks. How hard is it to install cams in LS1's compared to those engines? Any answers will be greatly appreciated.

Whats the reasoning of the 230/224 being on a 111lsa? Has anybody tried a 230/224 114lsa to compare against the 227/224 114, or possibly a 227/224 on a 111 to compare against the TR230? I'd like to know how much of that 7rwhp is from the LSA change and how much is from the 3 degrees duration. Lack of idle quality is fun for a few weeks and then it just gets old IMO. How far has LS1edit tuning gone to overcome big cams idle/drivability issues?

I thought tighter LSA's just moved the powerband farther down, but didn't really add much hp???

I have an XE-R 224/224 114. After looking the comparisons, I'm rethinking an upgrade to a 230/224. Not as huge gain. At a minimum, maybe I could live with with more 113 LSA for better drivability / emissions and grind a little advance in to keep the powerband usefull.
