Quest for 7's in the 1/8

maybe eventually.... At this point we are trying to keep the "stock farm truck" look. We still have the steel wheels with the dog dish hubcaps on it....
- Manual brakes completed. 6 lbs lighter, plus brakes won't bleed down when I try to brake-torque it, pushing me deeper in the stage. Hoping for a 100th off the 60 ft time
- Ordered the CFV crank pulley. Lighter, more weight off the crank, and smaller diameter, and shorter belt will be a few grams lighter LOL. My hope is a "split hair" quicker rev, and another 100th off the 60 foot time

- Bought a 2" spacer to get the air cleaner off the carb. I think any sort of velocity stack works
this is sort of the idea...QUESTION: Has anyone put a plastic fan on their clutch ?? I have a clutch fan and had thoughts of putting a plastic fan in place of the metal one on the clutch.

Frankly, I don't think the plastic fan for your clutch will be worth anything, except make your car a couple pounds lighter, and your wallet thinner.
You said you are still running steelies. That is the first place I would look for a performance increase. I can pull my 3 1/2" rear bumper exhaust, replace with header mufflers, change steelies and t/a's for centerline skinnies and slicks and save 150 lbs. Then there is also the heavy flywheel effect, from heavy wheels. The heavier the wheel, the harder/slower to accelerate.

If it will fit.....Why not!
Now, one of them Hmmmm thoughts.........
With the fan being lighter, will it engage sooner????
Putting a thought to my own question............................I think the fan blade trying to pull the air will be more resistance to the fan clutch activating then the weight!.?.....
So if the plastic fan pulls more air then it might not help.....maybe even steel a little bit of HP.
Maybe I'm way off base.

Speaking of brakes, you running a line lock??
And what were you running: headers? Exhaust with mufflers dumped at axle?
No line locks. Headers, and as of right now jegs turbo mufflers bolted to the collectors. I did it this way because the gas tank was in the way or I would have run the pipes back and dumped before the rear end. I used the Jegs because they came with an order of something some years back and I had them. Yep, better exhaust for sure will be coming.
I fully understand the steelies weigh. Same with the factory bench seat. We like the original farm truck look. And the end gate. End gate has to stay because my wife is in love with the colors and "DODGE RAM" lettering on it

It's why I asked if anyone has done it... Hoping to take the guess work out of it.
who would suspect this is a 12 second truck sitting here..... All steel and poverty caps, full bench seat, you get the picture. . .
What’s keeping you from installing a line lock? And you should run extensions vs mufflers if you can. There’s some weight saved right there.
Haven't found the need for line lock yet. Running ET street drag radials, and I don't turn them much in the water box. So far we are hooking. I have to have mufflers, it's driven on the street. Headers with just an extension would probably be very hard on my ears and .... the cops !! LOL
Gotcha, was talking extensions Just at the track!
Ear plugs! but not me. Love the racket. Removing My Ultraflos and short 3” pipes with dumps running 12” stainless extensions saves me about 40lbs iirc.Lithium battery saves about 30lbs but is a pricey endevour

I always race my cars at the track as they are when driven to the track. Takes about 1 hr for me to get there.... I do have a trailer now.Gotcha, was talking extensions Just at the track!
I tow my van but I always bring my exhaust with just in case the tow vehicle craps out. Did one time coming back from the strip (3 hour trip) and had to leave the tow vehicle at a closed Oreilys, threw the exhaust in the back of the van and carried on (1-1/2 hrs country drive left) I think I made it about 30 minutes before I relented. While I could stand the sound I had a few country towns left to roll through.....at night, there was no way that woulda worked.
Installed them and on I rolled.

My local tracks (other than special events) require mufflers (southern California, dont you know). They don't seem to be too conscientious about the regulations, however. I have heard more than a few that didn't sound particularly "mufflered". I'd like to try mine with just some collector extensions, versus header mufflers. Might get away with it once.
As of now, it looks like April 30 is opening day for the strip. New owners. Plan is to have Drag Truck (because they had to drag it from the farmers field... ) there and hopefully we have made enough "small, little changes" to at least have a chance at a 7.99 pass.

This is the day we are hoping for a run in the 7's ... and better yet, 1/4 mile !! Saturday !
Right now I have the cheapest Jegs turbo muffler on the truck that I had laying around. Think there would be any gain going to the Flowmaster FX straight through design ??

And, I've considered these, but I worry about "too loud".

What is your system now, besides the jegs turbo muffler(s).?
If it's easily removable/replaceable , I would put on straight thru 3" straight off the headers, as header mufflers, assuming 3"collectors on the headers.
Keep the turbos for street, swap on the header mufflers to race. (Heck, you could even run both setups as an A-B test.)
Whether they would be worth much, or anything, is always a gamble. How much return would you expect for your $100?
(I think engine masters test of turbos vs straight thru vs Flowmaster clones, showed about 10-20hp for the straight thru vs turbo, on a 450hp engine.
I'll see if I can find it to confirm.)
When I was a kid, I'd swap exhaust as often as my underwear. Well, almost as often.....
Right now my jegs mufflers are clamped right on the header collectors. How much of a gain would I hope for? If I got at least 1 full tenth, I'd probably pull the trigger. I don't want two forms (drag and street). I could swap at the strip and see what the difference is, but the fastest muffler stays on the truck. Yes, I watched the engine masters video
Budget blown no stock ones made.
Had a chance to get one (adaptor) reasonably a while back, but I didn't pull the trigger.
4 weeks to button things up. Trying to move from 8.2's to 7.9's in the 1/8th. Hopefully they'll run 1/4 and it will get to mark it's first 1320 pass. Already did manual brake swap and small crank pulley. Still need to :
- Kit for the carb
- Flowmaster FX straight through mufflers
- Hopefully some passes to mess with shift points and timing games....
