My 420A Race Car!!!!!

Just caught up on your thread. Amazing!! Really like all your innovation esp the dual wastegate with CO2 as a spring replacement.
Keep up the good work!

its been about a week since the last post. just wanted to see how the progress was going ZERO

 

[DSM-ZERO]

hmmm nothing yet.
Just got my drag rims in.
STILL doing the wiring.
My traction bars are done.
The other motor mounts are finished.
parachute bracket is finished and the handle mounted......


other than that im looking into getting a Borg Warner S372 shh.

Dang. See us normal folk were gonna try to one up you with the borg technology but looks like you got wise and realised you can do better than that turbo you have there.

Are you going to be doing any time attack or autoxing with this cart or just drag. I aske because it seems like you put a lot of money and thought into the suspension, I kow that suspension is a very overlooked thing in drag cars but I just think this is over engineering somewhat. Is this stup lighter than the stock setup?

 

[DSM-ZERO]

I wouldn't mind doing an auto-x event BUT it would just be for fun and plus i would have to get a smaller turbo and a different tune too...so NO i dont think ill be doing any auto cross

So then the question is why so much of an investment in a car that will only make left turns at the end of racing .

Good point. Well me and my little pockets might not understand but it is a bad ass setup. I just figured that it woould add weight and be overkill and actually slow the car down more than help it. But this shop seems like they know what they're doing.

DSMZERO.... I have been researching on traction bars for 2g fwd's for a while now, studying honda designs mostly and trying to apply that concept to a 2g.The L bracket that is mounted on your LCA would be putting a pretty good amount of stress on the bushing that it is mounted to after some hard launches. I would also box in that L bracket with some gussets for additional strength.... with the power you should be making you might bend that bracket on a hard launch! You might want to bring this point up with your shop. LMK what they say... I would like to know their opinions on my suggestions since they have been doing this for a while.

Well the bracket is 3/8 steel and i dont think it will bend it's pretty strong stuff. The shop says that is how they do it on all there honda's..

as far as pressure on the LCA the traction bars are only taking away its lateral movement to keep it from "wheel Hopping" it still retains all of its suspension flex...so it should be good.

very goos question by the way.

this is a vid of the ETD traction bar install for an 88-91 honda civic. Note the mounting location on the LCA. Just give you some food for thought. Under some hard launches that bushing will be pulled back and forth... Those bushings are not designed to withstand lateral movement. Figure I would give you some suggestions! I wanna see this build complete and put some #'s down!!!!

 

[pwnzer]

been watching this closely... no new updates just wondering wats up cant wait to see it done or atleast some dynos

Yeah I was looking at that too. I would be worried about it aquiring some play as the bushing inside the eyelid on the traction bar end starts to get warn from the force being put on it during hard launches at that kind of angle. The shop says that's how they do it to the hondas so I guess they have tested it before.

there could definitely be a more efficient design... just because it works doesn't mean its right! I would suggest revising that design but im only an amateur that did his homework. Good fab work otherwise

Very true but I'm a firm believer of it it aint broke....

Traction bars - FWD Guys check it out - Page 2 - DSMtalk Forums

I was thinking about looking into traction bars till I dug up this old thread off talk. I think I'll stick with what's I got and maybe invest in prothane bushing kit and window weld my roll stops.

 

[ILLegit420aT]

Very nice build, what road are you taking for fuel management? i just popped in

 

[DSM-ZERO]

im have a Electromotive Ted3r and ignition...

EVERYONE...get ready for Saturday!!!!!!

I have the whole day on the Dyno!!

 

[bullettdsm]

Zero, I want to hear about any lifting head issues. I don't remember what you did between the block and head (if anything). Arps? O-rings?

Good luck with the dyno and the lifting info is pretty important.

I know it's dyno day but take a look at that and check out how they angled the mounts at the bar so it wouldn't put any lateral force on the bearing/bushing.

Yep, been watching, craziest 420a build I've seen thus far. Let's finally see some results, hopefully you had no issues! Just curious if you're on leave or is the shop still doing all the work for you? Only a month left, congrats! Looks like I'll be heading back over there early next year. Lets see some results!
