if the converter is that much more tighter and efficient...you're gonna pick up a buttload of mph out the back door...I went from 167 mph to 181 mph with nothing more than a converter change...if he can get it up on boost at the line...it should take him for a ride
AWESOME
AWESOME
It's WAY tighter. We had the 2 step set at 4900 RPM and he could go to almost 6K before without the 2 step. Now it takes a full second to second and half to get to 4,000. And that's after I added 4 degrees of timing down low. I set the 2 step to 3600 and we saw 4 psi on the gage. How much timing do you guys throw at it on the 2 step. I have it at about 25* right now and then going down to 13* at 22#'s. We are running corn fuel and the plugs appear to say that the timing is good but I hear others that are making similar power at similar compressions running 24*+ with the corn. I'm wondering if the mark I'm seeing on the strap isn't the right mark. Dont know. He just switched to a #9 heat range NGK plug. I'm thinking that perhaps we are leaving a bit too much on the table.

Got one and a half passes tonite before snapping Scotty's input shaft. Kind of wierd that the last one lasted until the new converter and only been able to make 1 full pass since.
The one pass that he did get off, it 60'd like **** but it was expected. Added a bunch of timing down low to get up higher on the converter and the 2 step. Second pass built almost 9 psi and was heading for the bumper. Let off, got back in it and it was going for the bumper AGAIN. Let off, got back in it and SNAP!!!

what input shaft? New converter is loading it more obviously (less internal converter slip)

The concern about the converter is that Greg @ FTI asked Steve something about a bushing (which depends on the glide I guess) in the specs of the converter and Steve wasn't really sure so he told him to build it the same as the last one. Not sure if getting that wrong would cause these issues or if it's just the power.
The one good pass was an 8.45 @ 171.5 w/ a 1.45 60'. Once he got going, the power came on all the sudden and he broke loose and pedaled. Still went a best MPH despite forgeting to turn on the A2W and charge temps being 60* higher than usual.

From what I was able to find on line about the number on the shaft, it was a TCI Vaccu Melt 300. I think its a soft one. He ordered the bad boy from Rossler on Thursday. Hopefully it'll be here in time to make next Wednesday test and tune. The new shaft doesnt have the oring grooves in it which are the weak point. Apparently with this new shaft you cant use the trans pump to pump fluid thru the trans cooler.

The "bushing" he is asking about is in the pump... it effects the Converter charge.. some have them...... lots more dont.. You have a really cold plug now so i would think you could run it to 30ish degrees timing when your getting on the brake...... and A/f in the mid 12s-13flat.... Rossler has the best stuff out.. But I run a Vasco Shaft from Mikes transmisssions behind a blown 526 with a whipple with a glide and its held up... AND.. Only Once even have i seen this... customer had a bushing style pump and trans king converter running 4.80s 1.14 .60 foots...... changes combos and pulled the trans and converter for inspection while it was out.. There was a little trash in the pump so it was replaced for a non bushing pump.... it dropped off to 1.18ish.. and no matter how much power he threw at it early it would not run early... but good mph but he said it was slow out of the gate ( ET wise ) and pick up a few mph out the back over normal runs... But this was a tested combo in a proven car

Just trying to figure out the new trans cooling system. He went with a thick cast pan that is cross drilled with water ports. We were hoping to be able to use the heater ports on the water pump to circulate the water but it just doesn't move the water fast enough once it's restricted down to the 1/8" ports. He's going to have to buy another pump now.
Ordered a new chromoly drive shaft with a billet slip yoke to replace the aluminum one with the regular slip yoke. The standard 1350 slip yokes seem to twist the splines once the 60' foot gets into the mid to low 1.3's with these heavy cars. I'm on my 3rd in the last year. This last Strange one lasted 2 high 1.2 60's.
He went ahead and got the big wheel studs for the back also as that was probably going to be the next problem.

With the ringless shaft I would suggest running the bushing in the pump. Without the bushing the converter can easily blow the fluid out of the converter and make it loose.
