I made 398rwhp with the TR224 and stock heads.

My friend Chris made 401rwhp with the TR224 and stock heads.

We both had stock rear ends with stock gears which made about a 15rwhp difference from our 12 bolts.

I was debating on whether my next mod should be a cam with valvetrain, or building up my stock drovetrain. My current mods are in the sig. And, what was your gas mileage like?

Sears

My mods at the time:
TR224 ( 941 springs )
FLPs w/ offroad pipes, 2.5" y-pipe
Borla Catback ( no plate )
ASP crank pulley
Whisper Lid
Stock MAF w/ screen removed
TR Ported TB
LS6 intake
Hays aluminum FW
Centerforce DF Clutch
ACPT CF driveahaft
Stock rear (3.42 gears)
TR6 plugs
Thundervolt 10.4 wires

Chris's mods were the same except he had Grotts, 3" y-pipe, a bullet in the I-pipe, Cartek clutch, stock driveshaft and flywheel. Both of our cars lost 15rwhp with the addition of a 12bolt with 4.10s.

I ran 11.80@116mph, he ran 11.81 @ 116mph the same day. We had very similar cars at the time. <img border="0" title="" alt="[Smile]" src="gr_stretch.gif" />

Isn't that a very low MPH for that kind of power? I know A4s are much different, but I ran 115 MPH w/ ~ 355 rwhp....

R U A LS1

for Jsears, no. My friend ran a 11.98@116 with a 1.8 short. its possible. Or on the other end of the spectrum you can run a 13.2 at 111 <img border="0" title="" alt="[Smile]" src="gr_stretch.gif" /> with a 2.3 short. high for that time.

116mph was with the 12bolt (4.10s) and about 12psi in the ET Drags. RWHP at the time was ~380rwhp and the car was ~3500lbs. Weather was 70* with 65% humidity. I won't compare cars times unless we run at the same time at the same track. <img border="0" title="" alt="[Smile]" src="gr_stretch.gif" />

I've seen several cars dyno with this cam. All of them put out good power and Thunder has nothing to hide. They are by far the best performance shop and have the best parts. If I had some things to do over again they would have done a lot more of my work.

most A4's will put out 350-360 on a cam while the M6s will see 380-390 with bolt ons. My friend in his 02WS6 with a Xtreme 224 cam put out 392hp with bolt ons

R U A LS1

No doubt Thunder RULES! I was just saying they quoted up around 380, and ive seen people with it only pull in the 360/370s. So i guess its with A4s and M6s. So with that, i would come to think about whether the specs on a cam like that or a slight variation from that to the hammer cam or other cam would make a difference when it comes to me choosing my cam. I wanted to choose a good cam, and sometime what everyone has isn't the best, but i guess in this case it is. I wanted to know this truth, as well as asking about cams without saying "help me choose a cam" because i have read those, and still wouldnt know where to start.

In particularly, the TR224 cam. I dont get how on thunder Racing's web site (and i do love their business and all, im just wondering) the dyno graph if im not mistaken, used to say that their 224 cam made some 380 rwhp or something up in that area. But most guys on the board are only seeing in the 360-370. Any insight? along with some other cams i read aobut making above 380 with stock heads.

How does this cam respond to Nitrous?

R U A LS1: The cars pulling the 380+rwhp numbers are typically 6-speed cars with all the bolt-ons and are tuned fairly well. The ones dynoing slightly less usually are missing a few of the key bolt-ons (ported TB, ASP pulley, LS6 intake, etc). Also, the tune is very important to getting good numbers out these cars as well.

Also, as Justin said, going from a stock 3:42 rearend to a 12-bolt w/ 4:10s usually will cost you ~15 "dyno" hp.

We had a '99 Trans Am 6-speed come in with just a Whisper lid, GMS MAF, Hooker shorty headers (no better than stock), stock y-pipe, and a Borla catback. The car dynoed 319rwhp/332rwtq. We installed a Thunder 224 112lsa cam in his car and it pulled 354rwhp/357rwtq with no other changes. He decided he wanted a little more power, so we installed Hooker longtubes w/ a 3" y-pipe (Random Tech cats), ASP pulley, LS6 intake, and a TR ported TB. He then pulled 386rwhp/374rwtq. He will be back soon for some custom tuning.
