Update-Hy-Gard made the converter too tight?

I have a 4.30 and a 5.14 gear set, and don't forget the convertor deal!!!!!!!!!!

On a side note.

With the Tractor Supply brand fluid we say a stall difference but with the thinner JD oil we don't see any difference. We run JD oil because it is cheap for us (we farm and get it in 250gal bulk tanks) and the flash point (fire) is higher which is important with our turbo deal. We've been running JD oil since 1998 in all our trans.

I sell a lot of Amsoil Compressor oil to guys around the country and they seem to love it but we figured what we have is working so why change.

I found the old dyno sheet but I can't find the cam card to save my ass...I will call Crower with the numbers and see what they have on it...It is less difference than I remembered it to be....



Current deal...

you've traded tq for hp.i'd change the cam.i think you can keep your hp and get the tq back and haul some ass with it.with a BBF tq is free,hp cost money.

At 5000 rpm the new cam is actually making close to the same torque...It seems to me they are not too far off?
The columns for torque and hp are flipped from one sheet to another.

that'd be more like it. i dont read instructions or ask for directions either. if your will'n to turn it a little harder put some more gear in it and it should help.it's gona be one of them "sweet spot"deals for sure.

Just put a 5800 - 6000 converter in it and it will run now.................

Hey Blake...do the torque numbers look too far off to you? I'll yank the converter out and have it loosened up if need be.
Thanks,
Jeff

No, not for the cam you have. Your making with in 5.4 ft lb's of the other cam and it's a good bit higher in the torque curve. In my opinion it will be faster with the new cam. I don't think the new cam is right for your engine but it will run faster when you get the converter leaving 300-400 above the torque peak.

But that being said , your going to have to shift it much higher than you did before. Just keep moving your shift point up until it gets as fast as it will run, or until you don't feel comfortable turning it anymore.

It should be faster than it was before, even with the tall gears you have.

Thanks for all the input fellas...I've never really had to run my stuff hard to go fast but, it looks like this deal wants the screw turned a little more...which is O.K. because the chassis seems to like it. I'll change the fluid, crank up the lauch and shift and let 'er eat.
I'll let ya'll know what happens........"Hold on tight to your saddle horn son...."
Again, thanks for the help.

No such thing as too much Cow Bell.................

yeah after looking at both sheets I's say the converter is more at fault here. If Coan cant get it right i know a fella that can...................


Twist that bitch...................... Lugging it is worse IMO.

You buy'um books and buy'um but do they listen!!!!!!!!!

Yea...it looked like some warm pancake syrup....
Here is the original cam......If anyone is still curious.

Yes, i'm curious about what the card says

I re-sized it...couldn't read it before...

Lem...If the card "says" anything...I might join the Circus with it. :D

Looks like 280*/286* ?

10-4

Old cam doesn't have enough split and the new cam is to big at .050 on the intake and to much overlap.

My vote is a cam and converter change............. But I know money can be a problem sometimes.

If my memory serves me well the Lo Vis Hy Gard is Hyrostatic Fluid which can also be subsituted with 10w motor oil. HyGard is hydraulic fluid similar to coventional trans fluid. (its been along time but I used work for a JD (yellow) dealership)

And, when the exh. duration gets bigger it may need a little wider lsa. Some more lift would not hurt either.

Except at Bowling Green at the NMRA World Finals '08
Where did you hang the tail light? In your shop?

Yep it is in the shop............ I guess that was to much Cow Bell.............

Hope to have two laying on the track this year

Just an update....I swapped out the fluid for some red stuff and it loosened the stall back up somewhat. I was watching the tach at the shift and it was falling back to 5600, which I think is fairly close.
I did not change the launch (3900) but I did turn the shift up to 6800, which it liked....didn't want to change too much at once.
The DA was at 4500' this weekend. I went through some old log books to see how it compared to similar conditions...turns out, I am only about a tenth off from where it used to be.
The tires I have on now are the tallest I have ran....(105 1/2" rollout.) A friend of mine has ran this tire before with a 565" BBC door car and they slowed him down almost a tenth vs. a 14X32" stiff sidewall. (Which is the tire I used to run.)
I'm gonna test again Wednesday and crank up the launch to about 5200 or so and see what happens.
