heirfaus Posted September 4, 2009 Report Share Posted September 4, 2009 realy then how do you explane my car not over heating when it idols ! Dunno, it's just one of those concepts that stick in my head since I went to college to be a tech years ago... Quote Link to comment
lynchfourtwenty Posted September 4, 2009 Report Share Posted September 4, 2009 BTW if you don't use a fan shroud you can just chuck the fan and save yourself the extra noise and small amount of power it takes to spin the fan. Without a shroud it will pull no air through the radiator..... i dont have a shroud either, my trucks fine.. Quote Link to comment
DISLEXICDIME Posted September 4, 2009 Author Report Share Posted September 4, 2009 i was always told that fan shrouds made fans more officiant. Quote Link to comment
heirfaus Posted September 4, 2009 Report Share Posted September 4, 2009 Not sure of the actual ratio. I may have to dig out my college books and review it and of course it would be different on every car, but eliminating the shroud will pull most all air moved by the fan from the sides since there is no resistance on the sides.

DISLEXICDIME Posted November 9, 2009 Author Report Share Posted November 9, 2009 so i found out today that the truck 5 speed in my car will not shift from first to second at 8000 rpm's but it will shift from 2nd to 3rd at 8 .and when it is spinning the tires while sliding side ways across a parking lot it shoots small fire balls out of the exhaust :lol::D:p Quote Link to comment

JDM510 Posted November 9, 2009 Report Share Posted November 9, 2009 Thats a bad ass mikuni set up, I used to have that on my first dime I like how the linkage is on that set up best one IMO for dual carbs like that. Quote Link to comment

Yah i like the mikuni intake a lot more then the cannon intake i had before. I am still running my su's they will probably stay on the l for a while . I have bigger plans for the 45's on my other dime! Quote Link to comment
DISLEXICDIME Posted November 9, 2009 Author Report Share Posted November 9, 2009 after the couple 8000 burn outs and drift attempts that ended in 360's i think this trans is about to throw in the towel :( Any one want to put my new trans in. Quote Link to comment
DISLEXICDIME Posted November 23, 2009 Author Report Share Posted November 23, 2009 well i changed the trans seems to be in better shape then the last one. I also changed the u joints. ( thanks datsun mike for the write up ) But i still have the dam vibration. i noticed it gets worse if some one is in the back seat. :mad: man i wish i could figure this out ! I am thinking of trying to change out the trailing arm bushings next . Quote Link to comment
JDM510 Posted November 23, 2009 Report Share Posted November 23, 2009 ^^^itnerested to know what you find out it is Quote Link to comment
DISLEXICDIME Posted November 23, 2009 Author Report Share Posted November 23, 2009 you must have the same problem? jdm 510 are your wheels in your avatar pic 15x7 0 offset? Quote Link to comment
blueridgespeed Posted November 23, 2009 Report Share Posted November 23, 2009 (edited) well i changed the trans seems to be in better shape then the last one. I also changed the u joints. ( thanks datsun mike for the write up ) But i still have the dam vibration. i noticed it gets worse if some one is in the back seat. :mad: man i wish i could figure this out ! I am thinking of trying to change out the trailing arm bushings next . When I had my 510 lowered in the back AS FAR DOWN AS IT WOULD GO with BRE-style screw-jacks, It would vibrate in the rear under load. Similarly, I suspected the U-joints at first, but found them to be in good shape. When I raised the back end up just a hair, it went away. Turned the screw-jacks back down- the vibration came back. Problem isolated! Unless you're going to raise the differential (hard to do without fabrication) there's a practical limit to the angle of the rear half-shafts (and the U-joints in them) The u-joints can only articulate so far - and then they max out. You mentioning that it worse with someone in the back seat makes me think that's what's happening. For a quick check, put a 1/2" or 1" of shim material under the rear springs where they sit in the CA pockets, see if that cures it. I dunno where the discussion of the vibration started, I followed the thread back a little but didn't find it. - hope this helps.

I remember reading some of this same information from members on the realm, having vibration when putting the axles at the extreme limits. I think this is one of the reasons that the CV kits were a popular upgrade as they allow greater angles without vibration. Quote Link to comment

heirfaus Posted November 23, 2009 Report Share Posted November 23, 2009 what up chris where you ben hiding out ? you on winter brake yet ? I've been hiding in the text books :( Winter break isn't until December 9th :( Quote Link to comment
DISLEXICDIME Posted November 24, 2009 Author Report Share Posted November 24, 2009 hay blue ridge speed how low was your 510 befor you had the vibration issue ? got any pics so i can get an idea ? Quote Link to comment
DISLEXICDIME Posted November 30, 2009 Author Report Share Posted November 30, 2009 well its getting to the point where if i dont find the vibration in this car soon i am gutting it and starting on my green 4 door :mad: Quote Link to comment
lynchfourtwenty Posted November 30, 2009 Report Share Posted November 30, 2009 would be funny if you did that an the other one developed a vibration haha.. what all have you checked? Quote Link to comment
DISLEXICDIME Posted November 30, 2009 Author Report Share Posted November 30, 2009 changed trans new drive line ujoints new trans mount swap half shafts 3 times changed a brake drum that had warped changed rear tires and jad them balanced . i just took it to lesschwab to have them balanc all 4 four. i should have it back in a hour or so i hope it was the tires but i dought it. i am buying new rubber spring holders for the rear ( mine are falling a part ) this should raise the rear I hope! We will see lol i checked the angl on the half shafts the ujoint hooked to the dif is at 7.5 degrees and the one at the hub is at 8.5 degrees. They are with in 1 degree of each other so i think they are ok. but when under load who knows hope fully when i raise it up the vibration will go a way. Any one know what the max angle is for the half shaft u joints i have herd 8 degree's and 10 degree's . Quote Link to comment
lynchfourtwenty Posted November 30, 2009 Report Share Posted November 30, 2009 seems like you've coverd all the basics.. hopefully they get it taken care of.. Quote Link to comment
