How much are you willing to lay out for each extra tenth off your ET? If it cost you $1K to switch to a roller from a solid cam and you get .2, is it worth $500 / tenth? If you put on a set of CNC heads that get you another .3, is it worth $1000 / tenth? Where do you draw the line?

Depends who is in the other lane.Seems sometime I would pay anything

I'm just a bracket racer but I love chasing e.t. and getting as much out of my car as possible. If I was to pick up a tenth I'd run a 5.96 in the 1/8th and that would be sweet. I'd spend $500 for that easy.

I put out about 50 grand for 2 tenths but still hoping for another tenth or so-and still spending.

Maybe I shuold ask how fast are you going and how much are you willing to spend to go a tenth faster.

it kinda depends on what tenth it is ie. 10.8 to 10.7 not a whole lot but 10.0 to 9.90 yes

Cost Vs ET gain is directly proportional to the current e/t your running.
The faster one goes for every tenth gained, the next tenth gets more difficult.

I tried my best to pick up a few tenth in the dragster I ran but picking up 4-5+ mph at that rate takes well over 100hp to see these gains. Not easily accomplished, by even cam changes etc, especially when your already running max effort stuff. Im sorry, switching carbs, intakes,headers,cams, timing changes, tuning stuff. Not one single thing alone would get you the gain needed. More than likely all the things needed to see good e/t gains. So in my case several thousand dollars would may or may not see some return at the strip.
Where as uncapping the headers, jetting, timing changes could net 1/2 second e/t going much slower, dollars spent..maybe zero.

I dont think its allways a money thing , Ive seen lots of low dollar 8k engines run faster than 20k riggs , Just depends on who is wrenchen on them

We'll see!

I think backwards... I always think, make it lighter,
cost less in most cases and is usually easier on parts

For my Cutlass going from a 16.7 @ 80mph (bone stock 2bbl 350, with 170K miles). The new mill is running about $800 total

I'll let you know this season

It's too bad the cost to gain ratio isn't linear. A tenth to me is worth whatever I can divert from other expenses. Which brings to mind the absolute cost saving miracle of nitrous. There's nothing that will buy a tenth faster, easier, or cheaper on almost any application. I'm an N/A guy now, but if I had to have a tenth that would be it.

Well, I just spent $900.00 and picked up a tenth over my previous best but, I know I`ll see a bit more. I know guys who have spent $4,000-$5,000 on transmissions to get a couple.

as much as i got,witch right now aint much,my last investment netted me 6 tenth,s and ended up at 1,000.00 bucks a tenth.

In my case ,a tenth would do nothing for me. 10.80's right now. I need a cage, belts, and some other small things to be "legal" No more racing. Easy tenths include , but not limited to ..
#1 less weight
2 balancing of engine
3 trans efficiency
4 headwork
5 carb efficiency
6 proper gearing
7 proper tires
8 proper suspension tuning
9 proper intake/head/carb matching
10 efficienct driving
11 FireCore50 Ignition Wires


There are a lot more , in-depth things, but I think these are all important.

when you say a tenth, are we talking 1/4mi. or 1/8mi. believe it's a lot easier to gain a tenth in the 1/4. don't think i'm a jerk, but it's a lot cheaper to get that tenth with your brain than with your wallet
