Thunder Racing = Mission accomplished!
Thunder Racing = Mission accomplished! Spent a few days down there last week for a new Thunder custom cam, ported TB, ASP UD Pulley, 3.90 gears, and dyno tuning.
Went from the MTI G1 cam to a 224/228 X-ER 110+0. Geoff specced it out for me knowing it's just for driving around town fun and I wanted more low end. And here I ended up gaining up top too.
New numbers are 415rwhp and 393rwtq. Lots of area under the curve too which is what I was hoping for, that and the new gears are gonna be fun. So far only driven it easily and cruised back from there and still managed 25mpg on my way home. The only bad thing is my car had a bad miss up on the top end near 6k after they had done the work. Luckily Geoff and others stayed around and tweaked this and that and pretty much solved the problem with only a few random misses on the last few dyno pulls(we think I got some bad gas while I was down there). I did run 2nd gear up to 6200 after I had 2 good tanks of 93 in it and it ran fine. Soon I'll have it dyno'ed at my local dyno for numbers all they way to 6500. Sheet attached.

Very impressive. I am considering 224/228 .581/.588, but I am uncertain what LSA and ICL would work best for me. I wish you had PP LS6 heads instead of the TEA’s. That is what I will probably use. Then I could ask you if you had to fly cut.
Amazing! You went to a smaller cam, yet picked up power down low and up high. Looks like a trend! Folks, you gotta start looking at proper valve events to maximize area under the curve. JasonG's cam is very mild, yet whooped up on a larger cam. Proper intake valve closing points, proper placement of overlap, and maximizing dynamic compression can make a small cam beat a larger cam. Congrats. Well done Thunder Racing.

Can't help ya much on the LS6 heads. I do know that the TEA5.3's valve drop is like .100 compared to .175 on stock 5.7's... someone correct me if I'm wrong? So when speaking with Geoff I wanted better drivability and more power down low, something that I could use with my TEA gold duals(hence the XER lobes), and something that I wouldn't have to worry about clearance problems with the heads. This is what Geoff suggested and I went for it. Keep in mind claying is the best way to know if you need to flycut. I figure if I had the time(and I was closer to TR) I could have took the time to measure PtV with my old cam first, see how much there was, and then spec out an even more custom cam possibly bigger than what I did get. Sorry I couldn't help.. just rambling now. Hopefully someone else will see this and post with some info for ya.
Thanks Patrick G, and for the advice about this when I was PM'ing you.

The gains would have likely been nonexistent without those two mods...Which is STILL great because it shows you dont need a big cam to make the power.... Last edited by cantdrv65; Aug 1, 2006 at 01:16 AM.

Well in a closer comparison when they tested it and had the missing problems before the 3.90's were installed it was around 420/425hp. Now without the missing the numbers would have been different but that might a better comparison than with the 3.90's. I dunno bout you all but I'm not sure I've seen anyone add a TB and UD pulley and 15-20hp. There has to be someone on here who has just done those mods and got some dyno numbers? Maybe they can chime in for us. Either way I'm quite pleased with the outcome of my "small" upgrades.

Nice numbers. Glad you are happy with the car. Thunder does top notch work. Plus you have a very clean car. I was able to check it out when I was there last week. Enjoy it and congrats on the nice numbers.
I want that cam. I was dead set on a 224/224 112 cam, but wished they made a 110 cam. Now I see they do.
I bet that thing lopes like a damn.... something that lopes really hard.
Next time you dyno that thing, record it. I want to hear it bad!
Good job man.

Yup still have the heads on there, still pulls really hard up top. I took it for a little spin today can't detect any missing now that I've ran 3 tankfulls through. As I said still pulls really hard up top and has alot more low end grunt. Driving around town is alot nicer with all this torque down low. I'm quite pleased.
I'll see if I can get an idle clip but lemme tell ya it's tamer than my previous cam. Instead of a chop/chop type idle it's now a fast chop type sound. Allmost might pass for stock to a normal person out there. lol Also, Thunder can custom grind you pretty much anything you want, just call down and talk to them.
I did find one problem today. I had nice ice cold A/C when I had the cam swap done but it seemed to get a bit warmer on the ride home. No biggie I thought... till today allmost 100 and high humidity and I have no A/C! Checked the belts thinking maybe it jumped off since I have the pulley installed, no go it's fine. I've had two cam swaps and still running on the stock charge since jan 2002. Could my A/C just need recharged? Any other thoughts or things to check on? Thanks.

Have a leak test done on your coolant lines. When we swapped my last cam, we tweaked the line going into the condensor coil. It slowly leaked out. An AC shop can find a leak really fast if that's what it is.

Could something like that cause my SES light to come on? Took a short spin today and it came on. Will be going to have the A/C looked at friday do I need the code scanned now too? If so I might have to hit up Advance and let them tell me what code it's throwing.
