Your car is #1. I've never seen a #1 guy go to the #2 guy and ask him how he got to be #2. Last time I checked, only the winners get asked weather they're going to disney land after the big game ![[patriot]](graemlins/patriot.gif) Talk to Drew about his amazing results with intake bias cam.

st5150,
No offense to season'd 88 but what is his car #1 of? What is his best time with HIM driving it? I'm pretty sure that whatever you are refering to by saying "#1" that you are wrong and Camara90 is #1 and 93lx342 is #2. Oh and both of them use intake biased cams.

You seem like a decently intelligent guy at times, however every time you make comments like this I think otherwise. How does one persons result with an intake biased cam that was custom ground for a completely different combo mean anything. I guess that since The Rick had terrible track results with his TFS stage 1 it means that the TFS #1 cam is "amazing" as well.

close, but here's what I have:
Camara90 11.61 119.87 1.74 Nitto's SAC
season'd 88 11.77 116.838 1.607 Slicks SAC
93lx342 11.79 118.7 1.88
for what it's worth Drew did run an 11.5 and Rhett's car was on top of the list for a bit until he hit me with the ugly stick and made me put *his* ET in there so there ya go.

Jeff, you missed my humor. I was poking fun at the guys that swear the universe revolves around the cam/valve train. I used Drew's case study as an example of where intake bias cams don't always gain power. Obviously Rhett's exhaust bias cam is working pretty kick ass for him. With out giving two $hits about cams, anyone can look at the timeslips of the three local AFR185 347 guys and say that they're all making pretty much the same RWHP.

Usually reverse split cams tend to make more HP but start getting risky with blown or especially nitrous applications where I think you wouldn't want to have the nitrous staying longer in the combustion chamber. No?? Am I wrong? ![[Razz]](tongue.gif)

The answer to this is very simple so try not to lose me here;
season'd 88's car has gone faster than Mikes and Nates. That makes it the fastest.
Was that complicated? ![[Wink]](wink.gif)

Not really, but since what Shauns car ran with you driving doesn't really "count" for Sawson then I figured neither should Rhett's.

Maybe I don't get something here, but I don't see how you can compare or even claim a MPH increase due to the cam when...
Test A) Drew driving Shaun's car with Bias Ply drag radials, a bum clutch (bum means burnt/broken/slipping for those that don't understand) and a stock 5.O cam = 119 mph
Test B) Same conditions as above but Shaun Driving = 120 mph
Test C) Shaun driving with a custom cam and nitto drag radials, fixed clutch, and a custom cam = 123 mph
Test D) Drew driving Shaun's car with an off road H pipe, custom cam and a fixed clutch = 125 mph.
Get over it, I think those are BS test conditions that don't count for proving anything, except that fixing your clutch and using an off road H pipe are great freak'n ideas

As usual, you're off on your assesment Swanson.
Drew ran 118, I ran 119 & when I did it the clutch was holding just fine. It wasn't till Drew started the 2nd gear burnouts that the clutch started slipping. (Sorry Drew....)
Speculate all you want. Truth is I changed tires, cam, & exhaust & picked up at least 6mph. Oh, & if you look at the 1/8th MPH between the 2 setups, you'll see a 5mph gain. Note that 5mph gain came from 'losing' power down low compared to the GT cam. The car still only gains ~26mph from 18th to 1/4. Same as with the GT cam. This is with 1.9 60fts on both types of tires..... I'm sure if I swapped out the gears for 3.55's I'd pick up another MPH. Maybe everybody should run the stock cam, 3.55 gears, & off-road exhaust & skip the custom cam cause nothing beats the stock GT cam! ![[Roll Eyes]](rolleyes.gif)
Oh, & don't forget the bag of ice!
& you still haven't posted a comparable setup that's running 99mph in the 1/8th at 3600lbs.

Sorry, I don't know of anyone that goes the stroker 331/GT40 iron heads/ 1200 cfm power adder route when building a 450 rwhp combo, trust me you would have known by now if I knew of a remotely similar combo. You also claimed on several posts that you ran 119 mph on a bum clutch. Want me to post the links? It wasn't until AFTER you ran 123 mph that your story changed to "119 mph was on the good clutch". Want me to post the links again?
So you want to get in on this space age lobe action or what?

you really think -7 rwhp = + 6 mph ?
One possibility is that amazing TQ curve (like a stock LS1 on a 150 shot) was too much for your tires, so you could never hook up.
So you dropped power and the car became more driveable under the now more driver-friendly (and tire friendly) weaker TQ curve.
The car hooks up better, and runs a better mph.

So post 10 boosted combos running 99mph in the 1/8th....including race-weight & tire used.
Guaranteed I have the lowest flowing heads and/or lowest boost.
