Hey, as long as the customer is happy, that's all that matters... so if what is being done and the order that it is being done in are what the customer wants.. then it's all good. My only point is that.. the 10 or so Hp that you lose from the 12 bolt.. makes no difference at the track, on the street, etc. etc... but the # that you post when dynoing on a stock axle is more impressive to those that have no clue about anything.... we all know that if guy XX comes out with a H/C setup that makse 440 to the tires, but thru a stock 10 bolt, and a AA comes out with a H/C setup that makes 430 but thru a 12 bolt.. you have the same thing.. but people that are clueless will go with XX because of the dyno #.

And for what it's worth.. my 12 bolt was broken in on a dyno..and the 4.10's make no more noise then the factory 10 bolt 3.42's did Dynoinga car with a new axle.. you're not gonna hurt anything.. unless the gearset was not properly installed, but in that case, driving down the road will be no better. Launching it off the limiter 10 minuted after installation.. that's a differnent story.

Just trying to make a point... 10 bolt to 12 bolt = minus 10 hp from the dyno #

A couple people said that my cam only setup power wasn't that great too... so I guess I should have left the 10 bolt in for a week and dyno'ed on that... makes for a more impressive dyno sheet. But, if that's all you're after, a dyno sheet.. why put a 12 bolt in a car I guess.

 

***!!!!

 

you got lucky with your 12 bolt man, mine was a howling bitch the minute i put it in, tracers is quite though. Its hit or miss. And also since shes going to 4:10's in the 12 bolt it will be even better then the 10 bolt at the track.

Also is don could do away with dyno numbers he would be the happiest man alive. He hates the dyno cause all people get caught on are the numbers.

Also i dont see your numbers or a track time, what has the car done? Tracers 11's jons 12.3 with headers, keiths 12.2 with tr230 cam only etc etc. None of them dynoed higher then 420, **** tracer was the only one in the 400's at the time come to think of it.

 

if its strictly a race car moser tells you pull to the line but if its a street car it needs a few heat cycles and 500 miles of break in to seat everything . to each there own . in this case number isnt a big deal but it will be better to get the street and dyno tune done before hand so the rear can be broken in the way we want it to

 

How about this, lets make everyone happy and when i/don or whoever post up some numbers, we'll specify that it is on the stock 10 bolt, and if they don't know that the 12 bolt will give some loss in numbers then whatever. I'm not trying to put on a show with my dyno numbers.. so who cares???

 

exactly i have no worries of you being unhappy anyway

 

Actually Dyno #'s mean **** to start with.I'll tune it to a dyno # then retune it to go fast on the street/track.And some people wonder why our 400hp "dyno" cars MPH and run faster than other shops 450hp "dyno" cars

 

Dammit Steph! You're spoiling all our fun! We want to act like idiots and fight about it!

Good idea though! Well I'm off to pick on Ace...

 

i have no worries either. i'm VERY confident with my car being in don's hands

 

you can pick on my driving ...

watch, after all this complaining about numbers, ill be the only person to not break 12's with h/c

 

and I'll be the only one in the 11's on a stock motor and manafolds at lvd

 

The only way you won't break 12's is if you miss 1st through 4th. Then you may run a mid 13.

 

Incase you haven't noticed,most of the people here don't even post there dyno #'s,well atleast what I do I wonder why Maybe it's because the cars are setup for the street/drag strip I can give you whatever dyno #'s you are looking for with some keyboard swipes We've been in this game for a long time and people have been fighting over dyno #'s forever.To me it doesn't matter if the car has a 10bolt or 12bolt or 9" or 8.8,I'm looking at timing/load tables and A/F.
As for breaking in a rear on a dyno,good luck.Not saying it's bad but I've seen my share of wrecked rears.Steph had no choice on when the rear was going in,I made the decission to install it after

 

Actually I remember watching another car hit a 1.6 60' ,12.6 at 114mph with a 420hp "dyno'd" car last year.Actually it was more than 1 pass without missing gears

 

I run 12's just ussing 1st and 2nd

 

oops i meant to say 13s... i had a dream about my car the other night and i couldnt even pull into the 13s after trying so hard

 

my bad, i'm a little slow sometimes...

 

You won't be, after you get your car back!

 

Guess you're right.. I know that some 12 bolts whine, others don't... but I thin kthat they all do after a couple hard launches.

I agree.. dyno #'s mean nothing... the MPH and the scale are the only real true #s that matter... because they take one part in that can not be factored in at the dyno... the operator!

I don't post my #'s because they were nothing to brag about IMO, but for whatever it's worth, it made 403 hp and 389 tq. Now I could get into a/f and 12 bolts and under the curve and all that, but people in the know like we all on here are... could care less. As for track times.. I haven't gone yet this year, and once I do, I'll post them, crappy or good, but with my heavy *** in the car.. that's been down a drag strip less than 30 times ever, and about 8 times in the last 2 years in the car I now have... it's safe to say that anyone that can drive, would go a substantial amount faster in my car... and I'm the first to admit it. Too bad I'm not going to the rental at LVD... you'd all have some REAL bad driving to make fun of... mine.


Don, I agree with what you are saying about dyno tune vs real life tune, the shop that I deal with only does one kind of tune.. one that's gonna work in real life. I wasn't trying to say you are attempting to pull the wool over the world's eyes, you have a good enough rep so that is not needed, hell I deal with teh shop that I work with mainly because they are close, and I am comfortable with the people there, and the results that I have gotten with each step have been more than satisfactory, 10 times better then the first place I went to, and I'll leave it at that. I agree 100% with you're comparison of your 400 hp cars and other laces 450 hp cars... I have been in one of those magic # cars before, and wondered why it didn't feel faster then it did. yesterday, I raced the guy on a street near where I live.. now it's a vortech supercharged h/c car, and I lost... but no where near the gap that I thought I should have lost by, and the owner of the car felt the same way, surprised how close our cars are. he is now considering bringign the car somewhere else, and getting the tune and the car checked out because of this... so I understand exactly where you are coming form.
I didn't wanna start a battle, just wanted to make a point. 10 bolt to 12 bolt = 10 hp on a dyno.

Now with that said, I guess I'm all done.

 

I think that I may want to take some of the "action" on your prediction...Actually, I'd like to line up w/you, Sonny.... WJ
