Made a few changes over the winter, 3.55 to 4.10, tighter front shocks(still not tight enough), air to water intercooler(60lb on the front end). 3825 race weight
Been stuck in the 1.30s finally got it acting right with a gear change. This was 1.24 on the rear tires, and pedaled 3 times and still managed to go a 5.29. So close to 4s I can feel it. https://youtu.be/x7e-ruxqxJQ
You racing no prep ? Try some radials and get on a prep surface , instant 4’s . Otherwise if you going in the 4’s with 1.20 60 foots , you making some power out the back !

Radials and normal weekly test and tune prep, so it’s basically no prep.

Radials with out decent prep , with a car like yours not going To work well . Get on a radial prep track and you will run well . Otherwise you compromise your potential.

Watching the vid , that’s a power wheelie . Get more weigh up front . Honestly it looks like it separating pretty fast . A tad tighter on the rear extension And more power early . But it will need better prep . What ECU ? A ride height sensor or Davis VPS will help a lot

Been awhile since I've seen this thing run in person. Cool ride for sure. As a few of you know, deep down I'm an F body guy. The fact that it is so quick and is not light is really impressive. Doug

Still chipping away. Watched a lot of video of the last outing and determined the rear is separating too fast when the power comes in. Went and ran a true street class Friday, 275, tags and insurance ect. Front rd one it kept getting better as far as wheelies, I kept tightening rear extension, never touched the boost controller or changed the tuneup. Went a best of 1.23 but averaged around 1.25 60’. I think it’ll take a bunch more with the new shock adjustment, didn’t want to get too greedy with how consistent it was. Best et and mph was 5.16 139
That MPH in the 1/8 mile for that ET is really impressive: bow How much boost does it make with which blower or supercharger type and size are you using and if you don't mind what RPM does it leave the starting line at and what shift RPM and finish line RPM does it cross at: The reason I'm asking these questions is that I'm the middle of buying parts for a crank driven Vortech super charger for my new drag car, BB on E85 with B1-MC heads in a 1965 Dart back half car for the local northwest no prep series races next year

It lifts the front tires when it runs out of extension in the rear.... If you can slow down the rear extension, or get some more travel out of the rear, it will help you keep the nose down
Car is super awesome and the more guys running Gen3 hemis, the more support we should be able to get from aftermarket industry

4200 and 8-12lb on the leave. Shifting at 7800. Centrifugal blower is probably going to differ some as far as boost launch since boost is rpm, timing control will be your friend

Agreed. A lot farther than I thought an oem block and some stock heads with aftermarket springs in them would go. I’d really like holley to come out with a low ram intake so I can use a shearer intercooler lid and not have a bunch of stuff sticking out the hood.

Yes 03-08 block with 15 6.4 truck heads.
Thank you....you have a strong combo to run 137-140 @3800 lbs

Well chipping away but still struggling with climbing the ring gear. Got rid of the steel rear bumper. Total weight with brackets was 70lb, used a 68-73 glass nova rear bumper, don’t tell anyone. Made this pass and then it rained unfortunately. Pedaled twice to keep the wheelie down but still managed a PB 60’ 330 and 1/8. Would have been a 5.0x if it would’ve stayed down. We will get it there. Also needs a touch more preload in the left caltrac bar https://youtu.be/CtMvw-D3Eoc

I can take some more in better lighting; the first pic is it just mocked up. Had to do some trimming on it, and it could be better but it’s not a show car. I’m going to vinyl wrap them silver this winter most likely.
This car has always impressed the Hell out of me with the 140@3800lbs with basically a stock base gen 3 . Now i know that there is other gen 3 hemis out there but you or at least I don't hear much about them

I'm getting ready to narrow mine. I tried a 70-72 Duster front bumper on the rear. It's close but the 1/4 panel dimensions up/down are about 1 1/2" taller than the bumper. The Nova bumper looks like a decent fit. Doug

What is the gear in your trans and the rear gear??
Also when you make a tube or "normal" front end and get rid of all that transverse T bars, Go a little heavy on the front springs to calm down all that stored energy and pitch rotation. Also when taking weight off the front , IF you can, slide the engine forward an inch or so, youll be amazed at what it does for the bias without adding weight to the car. Good luck, you have a TON of potential in this combo

1.80/4.10
Theres part of your problem, get rid of the 1.80 probably need 1.49 or 1.58 depend on what trans you have.
Been a few busy weeks. Ended up nipping a headgasket and damaging the head. Decided to pull the engine as it’s been 3 years. Bearings and everything look so good I’d reuse them if I didn’t already have new. Got a new head from the dealer and everything is going back together this weekend. Some valve springs were a little low 100lb on the seat should be around 150lb so I’m sure there’s some power to be had there. Did manage to go 5.17 at 118 on the pass with the expired headgasket, I’d like to think it was a 5.0-4.9 pass but I don’t want to dwell on that. Sent the injectors off to be flowed and they were a touch dirty and the particular cylinder was 7% off from the rest leading to head gasket issue.
Once the engine is back together this weekend the foxbody front suspension stuff will be going down.
I have seen this car run there is a lot left in it it seems to be a hand full at times it will start lifting the wheels down track when he soft on launch.when I have seen it was test and tune the don't do a lot to the track he does a good job useing his head to stay out of to much trouble when it makes a good pass its a bear but I don't think I ever seen him make a pass that the car is capable of but it's fun to watch
I think I’ve decided to give it one more go with the transverse torsion bars. By my math doing foxbody front suspension, im dropping 200lb which will put me around 48% on the nose which won’t help with power wheelies. As much as I’d like to do it I think it will hurt unless I take more weight out of the rear to counteract it(which is tough)
We will see though. I may get bored in the garage and just cut it off. I think it will still go a 4 with the torsion bars:
No crazy winter upgrades, swapped some custom valved afco bgx rear shocks on, and switched to the new holley smart coils for the hemi to fire both plugs. Hopefully get to the track next month, picked up another project, and I’d rather have it done first. may start another thread specifically for it. It’s getting a stock 5.7 and a 727, and holley efi, and I’m going to try and go 9s with it for as cheap as possible, hopefully under $7500 or so.

Just need a wagon to complete the trifecta!

If I could find a ratty old brown 80 wagon I’d probably sell my hemi d100 to make room if I had to 😂
Tried out the afco bgx rear shocks. Not too pleased. Can’t get the compression on the rear tight enough. Just wants to spin. Going back to the cheap Vikings that got me a 1.22 60’
Have the afcos revalved, easy fix when they are sold new if oyu do not call and talk to them they have "generic" valving in them. The big advantage to that shock is all the big name shock guys can revalve them as well as Afco.
"I am not ashamed to confess I am ignorant of what I do not know."
Still riding the struggle bus. Only power change I’ve made would be firing 16 plugs vs 8 and a way better valve spring combo. Between the two it’s making way more power, so dialing the power management part in is throwing me for a loop. Potential bad MT tires are playing a roll as well. So I’ll know more once I test again on the radials. With it spinning off the hit and then getting back into it it went 128mph to the 1/8 with 8* of timing(15* last year) and 10lb boost less than last year when it went 139 not spinning so it’s definitely making some steam.
....That's a bad Boy there don't hear a lot about those late model hemi's much and at 3800 lbs
