josh one thing thats helped me was to put extentions on the rubber snubers over the out knuckles . my car has coilovers and was breaking 1/2 shafts cuz the shafts were going into the negitive angle . i ended up setting them up with1/4 in on the passenger side and just bearly touching on the drivers side so the car launched straight .they are easy to build or you can contact bill boudreau the zfdoc who blueprints the zf tranny also ,i showed him what i came up with and he is now selling them 602 319 6575 . his trannys are amazing he has special detants that makes it almost impossible to hit any other gear than 3rd at the strip .he a great guy and a good friend if you call him tell him i sent ya .i am going to try removing the sway bar and only running 1/2 tank of gas this weekend if it doesnt rain again

i should have shared that i do my burnouts in second gear /also use a line lock while doing a burnout so i dont fry my brakes ,the line lock sure makes doing burnouts with a manual car alot easier than dropping the clutch and hitting the brakes .dont use the linelock at the starting line

this thread got me to thinking *(hard to do at 57)lol so i started playing with the tips of my exhaust and found this out .if the tips end even with to 2 in past the valance the car even with my quiet exhaust has the 1700-2100 rpm drone once they get 3 inches past the valance the drone stops . i also used some of that heat wrap tape thats used on headers on the tips which helped . the reason for the wrap was after we put the car on a rack and reved it to the drone area i put my hand on the tips and could feel them vibrating . so from what i found out make sure the tips go at least 3 inches past the valance to help keep the drone out of the cabin . and wrapping the exhaust with the header wrap tape (used to keep heat in ) might also help. it never ceases to amaze me what happens when you start playing with things. hope this may help those of you with cabin drone . i understand that the exhaust tipps might not look as good extended, but it might save some from having to buy so much excederin

yes it does . might be the fact that the valve lift is only 405 but you have to remember thats 2x. lack of lift might cause the exhaust not to pulse as much?????

i put this ? to the guys at the tech dept at nitto concerning the nto5r drag radial and this is what they said . go thru the water box and do an aprox 4 sec burnout on the first run of the day and 21/2 -3 sec after . the tire operates best at temps between 160 -200 measured in 3 places left center right . tire pressure starting point is 20 lb and go down in 1/2 lb incraments . dont go below 15 lbs and you might start having tire slippage on the rim around 16.5-17 lbs. the reason they want you thru the water box is to minimize the chance of water getting slashed on the inner wheel well and dripping onto the tire at the starting line .hope this helps

the bad thing is they are going to be extreamly pricey 1500 for the whole system and wont sell just the mufflers . a cheaper way to quiet is to put some dyna flow 3 in super turbos on her with dual 21/2 in out lets . have this set up on my 92 zr1 with 23/4 in pipe and a 3 in summit xpipe . the car is almost as quiet as the stk setup and no drone . have a vid of the setup on utube pm me your email and i will send you the clip of it running at the strip to see if it has the sound you are looking for. super turbos from summit 120 and xpipe 86 ,just add the tipps you want and you have a system thats quiet and wont cost you any power promise

josh have been in contact with nitto tech about the nto5r tire and heres what they said optimum tire temp after the burn out is between 160 and 200 measured at left side center and right side . they said to start at 20lbs and go down in 1/2 lb incraments but go no lower than 15 and i might get tire slip on the rim at 17. nice 60fts .can hardly wait till next sat at fontana sure wish there was a track that did weekly deals

the denny kit is absolutly the best u joint you can put in a c4plus these u joints you can press the cups that go onto the rear diff and stub axles towards the center of the ujoint and you will hear a little click which locks them on so they wont fall off during install .

i read an article where the dyno max guys did an exhaust for a mustang 342 drag car. where they went from 3in collector. down to a 21/2 in expipe then out oof the xpipe went to 31/2 in for about 2 feet to the mufflers . test said they made the same power as open headers . kinda makes one one to try some stuff outside the nornmal thinkin . bbut as ron knows i have been chasing the exhaust majic box for 3 years . guess i find it fun to keep trying different things. i would like to have all the cash i have spent on exhaust systems . lets see current inventory . corsa , flowmaster , dr gas custom with spinteck mufflers (on the 90) borlas sq tips mufflers21/2in )stk 90 stk 92, and my minagery on the 92.and also have a custom randy wood 3 in stainless pipe that kinda looks like an xpipe except the opening between the pipe is about 10 in and squared. i was thinking about trying it but thought i might loose to much low end tq.whatc do you think about that center piece ron ????

i have one of the good one the pro rr . .if its reading off compared to the track times you just have to adjust the pitch degrees. you should also have the weight right . i like it for the fact it has a neat shift light and also for the info it can provide when you download your runs on your computor . you can see your wheel spin off the line as well as gear changes . you can also see if you are reving the motor too high and adjust that as well as being able to see how long it takes you to change gears . by adjusting mine its with in .07 on the et and within .6 on the mph. the cheaper unit doesnt have the ability to download on your computor nor do you get the disk for the program that allows you to see a bunch of cool thing .i find it a usefull tool for improving my driving tech at the strip.

on the pic .hehe dont think a pic of my levis would go over too well with the moderator.i have hardly any drone with the 3 in super turbos. i think that the 21/2 in super turbos would solve that.talked with hib today and he said the reason gm put in the second balance pipe (h pipe)was to smooth the exhaust note in the back of the car where the resonance was comming from . i understand wanting to hear those costly horses but what i find more satisfying . is for them to think my car being so quiet its an easy beat . then they see my bumper and their mind gets blown. plus there is the added benifit of the cops not turning around when they hear my car go by . the second balance tube sounds like something worth doing . i dont have any experience with what the single opening super turbos would sound like on our cars . since the 90-1 zr1s had 4 exhaust tips thats where i went because i wanted the sysem to look totally factory stk.

sounds nice and nasty . does the exhaust sill have cats? and does the chambered setup have a balance tube .if not you could do 2of them actually 1 up front where the pipes merge close to go down the tunnel and another just before the pipes flair out to go to the mufflers. in 96 gm did this on the lt4(back tube)to help with cabin drone . ck hib halversons article on how to make 28 rwhp increase over the stk zr1 exhaust .

i could come down one day with my gtech. i use it at the strip all the time .it has a shift light and its the one you can download your runs on your computor once you get home has a ton of different graphs . can tell how much wheel spin yopu have off the line and gear changes . can even tell you if you are shifting at the right rpms.how long it takes you to shift.fun little machine it accurate to within a tenth and a 1/2 mile an hr . has helped me tons in dropping my ets at the strip . glad you at least got her up and runnin once you get the little stuff dialed in , your going to have that good old perma grin . i love firing up my old 68 mustang with that big old solid lifter cam in her . get goose bumps just thinkin about it . enjoy all your hard work pards

so did you finally get a chance to get that pretty el camino running?the 90 with the old flowmaster cat back made 409.9 rwhp and 373.66 tqmax rpms 6800 on the hp and max tq rpms5400 at 2400 rpms tq is335 on the 92with the original corsa exhaustit made 393.2rwhp @6700rpms and361.9 rwqtq@5200rpms .300 wrtq@2500 rpms . i need to go to a dyno and retest them both with the current exhaust. but i think each of their hp levels have gone up 15 aprox buy the improvement in et and mph . the 90 went 116.70 with the flow master and with the dr gas , spin tech setup went 119.85 the 92 went 116.20 and with the current set up went 117.90mile an hr. what size x pipe do you think i out to try 21/2 in or 3 in then back into the 23/4 in pipe . the narrow xpipes from summit arent very expensive maybe i will get both to see what the power and sound levels are .being an old fella (58)i kinda would like the quietest exhaust i can get without loosing too much power . the 3 in dyno max super turbos flow 411 cfm each. i think the real hot setup would be to have that vacume operated valve on one of the tips like the new vets have . may have to see if i can find someone thats figured it out . the new b and b exhaust for the zr1 has that feature.the spin tech is a little drone at 2200 rpm cruize and pretty loud when you floor it . make the car sound a little like a ferarri so others say. opps sorry dont know how to spell italian

ron i beg to differ with you just listen to the vid of the white car @fontana. its as quiet as a stk car with headers when cruizing and isnt that loud when its at wide open throttle . before you say no way listen and then tell me what you think . or go to fontana on sat and hear for yourself . i agree that the ladder system may not be the best, but am trying to decide between going from 23/4 to 21/2 in x pipe or a 3 in xpipe . i have found that a 3 in exhaust on either of my zr1s causes the car to lose about 2-3 tenths ans almost 2 mph at the strip . one thing i found with the c4 is that the drone in the cabin is greatly. reduced if you carry the exhaust tipps 3 in past the valance . and the drone gets worse the closer the tips get to the valance .plus i keep the tip 15 mm below the top of the valance which helped too. a buddy of mine wants me to try some 21/2 in super turbos to see if we can get her even quieter . his thinking is the mufflers being at the end of the system that the 21/2 opening might not slow the car down at all.he says the dyno max super turbos even in 21/2 in form flow almost 400 cfm each .

my 90 zr1 is ported inj housings and plenum, headers, fidanza fly wheel,henderson tune , and a custom dr gas exhaust with spin tech mufflers with xpipe .its a 21/2in system ,410 gears ,that car has gone 12.10 @119.85mph the other is a callaway 475super natural , that i added headers to,its has 3.90 gears and a fidanza flywheel, bought the car with a corsa at that time the best the car ran was 12.48@116.19 mph. installed a 23/4 desert development exhaust i bought used added 3 ininlet super turbos with 21/2 in dual outlets.and puut the stk zr1 tips from a stk exhaust and the car has gone 11.94@117.90 mph in 95 deg weather .to be honest part of the et improvement was switching over to the new nitto drag radials . but a almost 2 mph improvement in much lousier weather conditions. let me know i was on the right tract. this exhaust doent have an xpipe persaybut it has t 3 in by 2 in tall what looks like thick rulers that go from one pipe to the other where the pipe bend to go down the tunnel . i am thinking of getting one of those narrow xpipe from summit and see what it does . this system is as quiet as a stk system with headers . i dont have cats on either car as i live in the only county in california that doesnt have to smog every 2 years .

this is something i have gone way to nuts about trying to find the most powerfull yet really quiet exhaust for my 2 zr1s . what type of exhaust do you have and how do you feel about it pros and cons . just would like to hear what ya all have and what you think about it

one thing i have found with both the nittos and mickeys in the 315x35x17size on 11 in rims is that if i go down below 18-19lbs is the center of the tire starts to get a valley bow in it . the mickeys seemed to like a big smokey burn out , the nittos not so much just a couple of seconds. they didnt bite worth a darn when we did a big burn out . a genleman named ranger sugested i do a short second gear burnout and said to mmake sure i back into the water box then roll out to the front edge of it so to minimize water getting on the wheel wells and front tires . never had thought of it much before as all my other race cars have front runners on them my zr1s i run the standard 275x40x17 tires pumped up to 50 lbs at the strip

i only use the nto5s when i race. but i do have to drive 195 miles each way to do so. so i guess i have about 2k miles on them and 25 runs and they hardly have shown any wear

also we might try a set of 345s for kicks in one of the cars . the lt5 gets rpms so darn quick and tons of tq down low make launching with 390- 410 like skating on ice ,. i think that 1.6-7 might be alot more possible with 3.45s my buddy pete in the midwest has run 11.04@128+ mph with a fully ported and cammed yet stk cubed zr1, and he still uses the 3.45,in fact he tried the 4.10s and went slower .he is on utube also . you should ck it out it sounds awsome

i wish i knew , have had a couple of friends try the car out and its the same for them , they feel the tire is part of the problem too stiff a side wall for a manual. we are going to fontana this weekend and going to remove the front sway barand try some rubber snubber extentions i made for the car so that she will only squat about 1/2 in . will share the results . also these nittos seem to 60 ft the same from 24-16 lbs . plus my car weighs 3650 lbs and the lt5 motor is heavier by about 100-125 lbs which isnt good .with my mile an hr sure would think that 1150-60 would be possible . dont want to go any faster as i dont want to istall a roll bar. i have an 88 mustang with an lt5 and auto that i use when i want to go alot quicker . but its so pretty and new its hard to go out and flog her . it sure drives my ford buddies nuts though

i have 2 zr1s a 90 thats has headers ported inj housing and plenum a custom dr gas exhaust fidanza flywheel and 410 gears and a callaway 475super natural92zr1 with headers and 390 gears . vids on utube under bradzr1 just click on my favs . if your dads car has the stk flywheel, that limits his launch rpm to 2000 nothing more even with drs . and the tech that works the best is to slow let out the clutch ie first 3-10 and roll into the throttle instead of the standard dump the clutch and slam the gas . if he is using street tires then it becomes even dicier . stk tires 22-25 lbs and leave from an idle and feed the car gas slowly . i know its tough to do. its drag racing but he will run faster this way . i have been drag racing since 1971 and its tough for me to get into the 1.7s 60fts . i do believe that the 315x35x17 have too short a sidewall for a manual car . that the 275 or 285 x40 x17 would work better even thought he tire is narrower . next step is some slicks , but then things have a funny way of breaking . best mod to the c4 irs is the spicer 799 series u joints ,dennys drive shafts sell a kit for both 1/2 shafts and drive shaft. good ins . busting a drive shaft can also mess up your body pretty bad . have a great day.also finally i think that the 3.45s are just as fast at the strip , easier to launch and 1 less gear change for the zr1 top of 3rd instead of top of 4th. a friend i IILonois proved that out . feel free to pm me if i can answer any other ?s for you

you should try the nto5rs they are way better . i had mts 315x35x17 before and the new nittos are way better for me . friends have said i should go to the 275x40x17, saying the larger sidewall would help with my launch

josh do your nittos have 3 large grooves in them i think they are nto5rs . what tire pressures did you run in them. i have a set and am trying to get ideas of what pressures work best , i have a zr1 that has run a best of 11.94@117.80 but my 60fts are 1.84 best with alot of them being in the high 190s. are you running the fx3 shocks and if so what setting are you using . thanx for any guidence you can give on launching techs
