The reason I run them is for street strip use, for the track I have the shocks with 5 psi & 1/2 round of preload on the Caltrac bars, then for street driving I bring the pressure up to 15 psi & it unloads the Caltracs for street use, I REALLY want some Double adjustable coil overs with a VERY soft spring to accomplish my set up, BUT $700.00 for shocks is not in the budget, the air shocks seem to work good though, we will see how good with the 4.1 gear next time out.

Yes

You might add some double adjustable shocks to your list of things to try. I know my car even when it 60d slower than it does now had way to much separation when I tried to run with those when I broke one of my rancho shocks.

Edit I just saw your other post. You might look into the Viking double adjustable shocks. I know mine were way less than $700 and I have been real happy with them.

that is my next thing, saving up for them , I appreciate the advise

Look at buying Afco also, better quality and a better price also

do you also race it with front and rear anti-sway bars?

Yes I drive to the track, let out about 7 psi from the rear tires, deflate the rear shocks & make a pass. I also turn off the ac

I also turn off the ac

Awesome!![color:#FF0000][/color]

Talked to the Austin who runs the track HRP, looks like November for some more Track rentals, on another note, I REALLY love 69 Charger Daytona's & have planned on building mine as a restomod CLONE, I saved for over 4 years for this wing. it is Hollow aluminum casting like the original Daytona wings,, no flimsy fiberglass here, made my Dane & Justin Gjesdal, he has built quite a few Daytona clones, next will be the nose & then the window, but that will not be anytime soon.

what are you going to do about the rear window ?
my one buddy found a perfect vega hatch with the glass and all the trim for only $50 at a swap meet this summer for his clone. he couldn't believe his eyes when he saw it sitting there.

Not sure yet on the rear window, If & when I do it I think I will make a steel window plug & get a Lexan Daytona window , The nose will come 1st & will get a Janak one, all this will have to wait for awhile, as you would understand, I need some things done & modified on my house, or sell this one & get one built with the things I NEED to make my life more tolerable, the struggle is real LOL, hear is a Picture of Brain Damage escaping with the new wing. Hope all is going well for you !!!!

that looks mean ! [not that it didn't look mean before.]
as to the "struggle", i know all too well. sometime i'll fill you in on the latest.........

Well ,, went to the track on Friday the 13th , track rental $200 bucks & was only able to do one run,,, not bad about 20 cars, no road closures or detours this time so it was only 126 mile round trip, weather was nice 1550 DA, want to just make an easy 1st pass with the new 4.10 gear, car leaves very nice & smooth, I get just past the 1/8 & it starts laying down & burpin & fartin, click it into Overdrive thinking I was floating the valves, that was not the case, me & my FUEL VOLUME problems LOL!!!! VERY glad I have a Data log system, lookin at the fuel cells the ECU was adding 80% + fuel & all I had to do was look at the log for the fuel pressure & THERE it was, went from 55 psi to 30 to 20 to 6 psi & soon as I lifted it went right back to 55 psi, I will do the same volume test that Dwayne had me do last time I had problems when it had a Carburetor, I REALLY think my Fuel filter cant keep up, I ordered a new large 460GPH EFI filter & will do a 55 psi volume test as it sits now & then with the new filter,, my pump is a in tank 450 LPH pump, good for over 1k hp, sorry it took awhile for me to post about this, but I was so fed up with everything, I drove home, parked in the garage closed the door & haven't looked at the car since,,,, GRRRRRRRRR

TURN it up & listen

all the spikes are going off the scale lean & rich
on the left 8 psi fuel pressure

Sorry for the woes........ but it does highlight the importance of having the basic essentials ironed out.



450LPH........ at what pressure?

I’d say you need about 350LPH@ whatever the EFI system operates at(55psi??)

Its a 115 GPH @ 55 psi so 430ish LPH ,, also its hard to make a full pass on the street now days, the police are not very nice about 120ish MPH blast

Maybe I missed it but how much fuel in the tank?

Also where is the regulator and how is it plumbed?

3/4 tank, Baffled EFI tank, return system, regulator up front

I don’t run EFI, but it would seem to me that if there was enough of a restriction in the filter to cause the pressure to drop to 8 psi, the pressure would start to fall off pretty much right after going to WOT.
Is that how it looks on the data log?



700hp at a bsfc of .50 is about 58GPH(350LPH).

No, it waited till just after the 330 to start fluctuating & then by the 1/8 it was REALLY dropping , soon as I lifted its a stable 55 psi
