So I lost 4 tenths and 4 mph going to the Fuddle, around the same with nitrous, but the converter is much tighter, maybe it need more miles?

Why did you switch?

Drew778

iTrader: (2)

Well, the Yank was kind of loose for me and the Fuddle was supposed to be better with nitrous?

But this was only one night with the Fuddle, my first night with the Yank I wasn't impressed either.

well i think it did good comparing apples to oranges.. goin from a 2.6str to a 2.1 and loosing 400~600 rpm in stall im suprised it did that good..look at the N\A pass.. a fair camparo would be a 4000 vs. a 4000 just my .02 but good times nontheless!

Andrew, I agree on needing more seat time with the fuddle. I do recall when you went to the Yank you bitched and moaned about it for two three w/e's, then all of sudden one day you ran a NPB and it was the greatest TC on the planet. Give your car a new head gasket, which I'm sure hasnt been leaking one run, more like the whole time the fuddle has been in, and give it some more go-go later.

cant compare goin from 4000 to 3200 especially track times

rgriffin

Yeah what he said..

AutoRoc

There's no way you're car's making better power at 3200-3400 than 4000. The results look great when you think of it that way. I'd actually like to see the bottom 10's that a 4400 could have probably gotten you.

This is what happens when you get caught up in everything you read on here.

If you can handle that much stall with Nitrous you might as well run it. There is no way a lower rated converter would be better. Switch back ASAP.

1 Nitrous gets a bigger torque spike at lower rpm, some ppl are fine with this where other will design their combo to only arm higher in the rpm range.

2 On the bottle, stall is closer to 4000 than 3200, whereas with an NA run it should be right close to 3200. Its all dependent on how much torques is produced and what RPM?


2002_Z28.....yes there is a good reason, as stated above. You definately do not want to launch a 5100 stall car NA and then hit it with a 250 shot, youd have fun picking up the pieces unless all the components inside where fine with a 6000+ rpm launch at that amount of torque. Also, if the higher stall TC is not efficient, due to age, design or wtfe, then a newer, more efficient TC can be more than worth it.

Damn, now I motivated, I'll post some new times next weekend.

If everything will stay together, I'm sure I can beat my 150 shot Yank SS4000 10.7 time with this new Fuddle and a 150 shot.

Obviously, that is not what was happening or he wouldn't have been able to run that Yank converter for that long. Yank builds the converter with your HP in mind and the rating is pretty accurate. Efficiency is determined by the experience of the builder and quality of the parts AS WELL as the research into them. A higher stall converter is just as efficient % wise at the coupling RPM. You really have to test each converter rather than using general rules. Not all brands are equal!

Either way he was sold a product and told it could do something it couldn't.

This was just the first try, I'm not giving up yet, I was just sharing my results.

Stay tune it's not over yet

I had heard Yank was the most efficient converter out there. If that is true, it would explain your results and make it tough to beat it from an MPH standpoint.

Be sure to post the new numbers ASAP. I would really like to see if the number of runs could effect the performance. I don't see how it could in my mind.

slimcracka

iTrader: (7)

well he has to relearn the launch so well see!

PREDATOR-Z

I'm able to cut the times in my sig on a VIG 3200.
With a smaller stall and nitrous, a proportioning valve is a great asset to be able to brake stall closer to actual stall flashing point.
I cut 1.4x on 150 dry

No offense guy, but I think your not really understanding the whole issue here. You need to understand that Yank doesnt make TC off the shelf for your HP and his etc. They are off the shelf and have a broader spectrum of power rating than some others may have. Also, If your launching at a higher than rated rpm on motor, I personally would not want to try launching on a fair amount of nitrous, as it WILL blow past the rpm you launched at NA, thats a fact (unless the converter is specifically built for large shots of nitrous, which if it were, and it was stalling that far beyond NA it would be noted as TC that exceeded its usable life).
Do you use nitrous? Do you know that the lower the RPM the more torque it builds? Do you know some ppl set their heavy *** cars up for higher torque at lower rpm launches for a reason? Efficiency has little to do with the builder period. It has to do with the internal components of the TC, bottom line. You can alter the pitch of the blades and the TC will act totally different, change the sizing of the impeller or vanes, etc etc, just cause it has XXXXXXXX name on it doesnt mean ****. If it did, then everyone would have a Yank. FWIW I used to own a Yank, and have installed a few, to include the one just removed from Andrew's car, so I have some experience with them. Have a nice day.

Oh lest I forget, yes time can effect the results. You dont see how? Try launch technique, effects of DA, tuning and general seat time.
