Finally got around to posting my track times, for comparison sake, I ran an 11.42 at 119 MPH with a 1.65 60' (Trex). My TR230 best was an 11.45 at 117 MPH 1.59 60'. DA for the Trex was 893 ft, Temp was 71*, and DA for TR230 was 300 ft. Temp was 65*. Race weight was 3550 pounds. I think between the DA and the posi one legging it on the burnout's and out of the hole prevented me from hitting the 11.3's. The Trex, IMHO, is worth a good 2-3 MPH and 1 tenth over the TR230 cam. I shifted both cams at 6900 RPM and still use the stock 3.23 gears and an SS4000 TC. Anyway, I ran what I ran so take from it what you want .

I got brave at the end of the night with a 150 shot and I either over powered the TC making it slip in 1rst gear, or the 1-2 clutches slipped. I had to back out, shift to second, got back on it, then when it went to third, I had nothing at all, it was like being in neutral. So the Pro Yank finally gave up on me, but I still ran an 11.9 at 92 MPH 1.73 60',lol! That's tough when your 135 miles from home and you drove your car to the track. Lucky for me someone really helped out and trailered it home for me the next day..

neat comparison. congrats on the awesome times.

From looking at the graphs, 6900 ain't enough r's to take advantage of the cam. That's where a stock Z06 cam needs to shift. You'll see some huge gains if you can shift at 7200-7300 IMO.

ill let yall know wednesday how it likes 7200, weather is looking good.

I think your right about that! I have the motor for it but with the trans not shifting right on the 2-3 shift, I didn't want to bounce the limiter. Right now I have the shift point on the 2-3 shift set at 6600 RPM just so it will shift at 6900 RPM. If I set it to 6700, it will bounce the 7400 limiter...

nice work, good to see a comparison like that. from what you are saying it seems the T rex won the battle there

sorry to hear you broke, hope you get it back up and running soon

We run close to the same times on motor. But I gotta tell you, you must have some BIG ***** to spray a 150 shot on a car that goes low 11's N/A with a 4L60.

I would love to spray mine but I know the A4 is not going to like it at all !

I was hoping for a little luck with the 150 shot. The specs on the trans claims to hold up to 700 lbs. of torque but we can now see it won't. I honestly thought the 10 bolt would of went first.

I really posted this as more of a comparison for the people who thought the cam would actually do worse at the track then the TR230 would. Some people thought that a cam with less torque on the bottom end would do worse at the track, another reason I didn't want to move the shift points. I didn't want there to be any differences in the setup other than the two different cams.

Is it ok to spray w/ the TR230 cam? I was told that it was not the ideal cam for spray but if that cam works and can put the numbers out im going for that cam!

taqwache

acually you can spray 150 or so on any cam without problems. you will just have better results with a nitrous freindly one.

WHat do you mean nitrous friendly? will something blow up? Or will I not get the full power out of the spray?

SMOKIN01TA

nitrous cams have a high lsa like a 113 to keep from building up as much head pressure i think

Colonel

Wider LSA = less overlap and less intake charge bled off through the open exhaust valve (this bleeding is more pronounced at lower RPMs.) It also means the exiting exhaust charge has less pull on the entering intake charge (this pull is more pronounced at higher RPMs.) The increase or decrease in actual cylinder pressure due to LSA changes are in part RPM related and can be pretty complicated to fully understand.

hey, atleast i knew that part.
thats why i call and talk to the people who design them before picking mine.
i dont have enough free brain space to learn all that right now.

So colonel in order for me to spray I need a cam w/ more LSA? Where would I find a healthy cam & company out there that would sell this cam? I need a cam but am very lost I hate to try several different cams @ 3-5 dollars a piece eveytime.

Colonel

hawaii, if you're just going to spray a mild to moderate shot (say, under a 200 shot) I'd just pick the NA cam of your choice and spray it when you want to. I'd only make my cam choice N2O specific if you're REALLY going to get serious with the spray. In that case you'de want to be running a forged bottomend and lower CR pistons anyway. I think that's getting outside of the realm of what you're looking for.

Me? I'd run a 220-230 cam with a 112-116 LSA (these huge ranges given depending on application and goals.) Add juice when desired.
