Thanks alot guys. It is really nice to have it done. I got a few things to do and then I am going to a HUGE cruise over in Mississippi for four days....and THAT is gonna be a blast!!


I really thought the car would put down a tad more, but for now I am happy.

Again thanks guys.

What is your cars raceweight? And how much RWHP does it make?


David

 

it is about 3450 with me in it(I need a diet and so does the car)

made 451 rwhp@7300

 

David,

With the ring gear setup you have, gear oil, converter that's a easy 25% loss there. 475rwhp x 1.25% = 593 HP which seems a little more likely to me.

There is still some tricks there to get more out of the 9" in terms of efficency but's more Pro Stock type tricks.

I'm glad your happy with the numbers and you have a driveable car to go cruisin in.

That is good power and should be easy to jump into the 10's.

I would not get to wrapped up with the dyno numbers though...see how the car runs because if everyone only cared about dyno numbers we would all be running 6 speeds with 3.23 geared 10 bolts with LS1 driveshafts on stock radials.

Congrats and I am sure you have more in it.

 

Its actually not that bad, its a good n2o gear with a m6.

 

25% Locked? Do you really think it would be that high with the converter locked? Wow.

David

 

Unless you tweak them yes they are easily 22-25% Remember with a engine dyno you don't have accessories on the motor either, so the indicated flywheel HP is higher due to a lot of reasons.

 

With a lighter car I would agree, 10's would not be a problem. But at 3700lbs It might be close. Of course I have not weighed the car, just guessing. I put it all down on paper as to what I took out vs what went back in and it was basically a wash...so the weight is pretty close to my guess.

David

 

care to share. You can pm me if you like and don't want to share with everyone.

 

look at it this way. My car went 10.3s at 3310ish and dynoing 476rwhp. While that is 400 lbs difference I think your making more hp than my old motor. And it should 60' dang close to mine so my prediction is it will easily get in the 10s.

 

want to know also.....is it like running motor oil or putting the light buld behind the diff?

 

There are some good oils out there and good gears as well. That's where I would look.

 

I have Synthetic big truck 90 weight in mine, was orange in color. Good stuff.

What about Mikronite treating the gears?
