ive had a fuddle 3200 with 3.73 cam only and i use to cut 1.60 on motor....and id run 7.60 at 90
with the 125 shot it would cut 1.48-1.50 and run 7.0 at 99-100

now ive got a little more power (10hp, and 25 ft pounds) and a yank 3600 with 3.42 and i can get better than 1.78 60' on motor and on spray it cuts 1.60 and runs 6.80 at 103
i leave on a 125 shot and it has had traction problems so it might cut a 1.53 or so but not any better....

im about to switch to 3.89's

my question is im spraying a 200 shot i really dont care about n/a times although id like to get 1.6x 60' on motor and low 1.4 on spray (125-150) shot
im way more into it running fast on nitrous not motor...would yall reccomend waiting till i get the 3.90 and see how it runs? or should i go up to a 4000 now? and will the 4000 sacarfice top end mph? also if i go to a 4000 sized stall what series do you reccomend? currently ive got a ss3600
only reason im debating switching is because i hear yeanks are already under rated and i wanted a true 3600 compared to my old fuddle 3200 would have been perfect..but i wasnt happy with fuddles efficiency, thought it could be slightly better
i really like keeping the efficiency for mph/street runs

my car has the same gear/coverter set up and has only gone 1.6x once on motor and a best of 1.58 on 125 shot with a 3660 race weight. hope this helps i talked to yank and they said if i switched to a ss4000 i would need to raise my shift points to above 6600 to run the spray to keep from blowing thru the converter. i too wanted better na times with the SS3600

o yeah my shift points are at 6500 now...but i have no problem going top 6800 or so...which will i guess make the converter a little more efficient...

Wow it seems like that Yank is A LOT more efficient!!

you trying to shift into 4th gear?????

daniel6718

iTrader: (36)

no....but i can if i need...i would do some 4.5x gears if it wasnt a street car where i have to drive on the street/freeway...

whats wrong with shifting into 4th? i see you also have a cpt tranny...frank says its ok, as for now im doing 3.9 since its a street car

also i do way more 1/8 mile racing then 1/4

yea it is but look at how big of a hit my n/a times took? not a big deal to me...but im assuming to go faster with nitrous i have to go faster with motor...

i just have to get that best balance between nitrous e.t(size stall) and nitrous mph(efficiency)

GregWS6&z28

iTrader: (8)

oh, that would be ok since you race more 1/8th mile. I was just under the assumption that you wanted to stay in the 1:1 gear for max power and acceleration. I've read that it's hard on WOT shifts into 4th gear, especially under spray. Even on a built trans 4th seems to be a weakpoint. But I'm probably wrong. I have too much stall with my Yank SS4000 and a 150 shot. I'm pushing the converter and im running out of gear at the end of the track with 3.42's

daniel6718

iTrader: (36)

at 116 your outa gear with 3.42 then that converters not too efficient? or your shift points are at a low rpm


and frank has been asked and said its fine 3rd and 4th hold just as well as one another...so it would be fine...that would be awesome to do a 5.xx gear haha

trapping 127. nitrous is pushing the converter

My SS4000 and a 150 shot with 4.10 gears blew threw the converter, and ultimately blew my expensive built 4L60E. The SS4000 was great for N/A though.

My PY3400E with 3.23 gears worked awesome with a 150 shot, trapped 128 mph with a 1.60 sixty, back in the day.
