Which converter have you purchased?The hp series or the one that is $ 400.How do you like it so far?

 

I paid $400 for my 4400 stall. It drives like crazy, is quick as hell, but its a little loose. Granted, I'm still with 2.73 gears. For the money, you can't beat it.

 

i have the $400.00 converter as well. I was originally getting the hp series but john told me i didnt really need it. i have a 4k with a 2.4str and a ms3 cam with 3.23 gears. pull 1.65 60's on dr's. LOVE THE STALL. Best mod so far. I think its more fun than my old 6 speed car.

 

I bought the $400 performance converter. I cant say one bad thing about it.

 

Same here, 3600 stall speed and 2.2 str. I LOVE IT!!

 

I have Fuddle's performance converter as well. Its a 3400 stall with 2.1 STR.
I love it.

 

i have the cheapo, too. 4,000 stall speed. performs very well and i haven't had problem one out of it with ~10k hard miles.

 

i have the fuddle perfomance converter as well(400 bucks) im loving it

 

I had a Street Perf ($400) and it was great, 3600/2.2
I had a HP Series ($570) and it was very nice, locked it up a few times on WOT without issue, 4000/2.4.
We had one upgraded from Street to Race and that badboy didnt flinch when locked, just took what we threw at it and ran. 3400/1.9 I do believe.

 

I have the HP series 3200 2.1STR. I like it, alittle hard on gas but get out of the hole pretty hard. Dont have any 60ft times yet, Just installed it 2 weeks ago and havent taken it down the track yet.

 

i have the performance series and wouldnt change my selection. i have a 3200 stall, 2.0 STR, and the car runs great. traction in 1st is hard to come by, but oh well.

i only dropped .1 off my 60ft (1.9) and E/T (12.9) though. but, seeing as though it was a hot day (hotter than when i went before), and the track prep wasnt too good, im sure it could have been better drop. also, that was launching it the exact same way as i did the stocker (around 1500 RPMs). if i launched it any higher like i could have (say 2500RPMs), it would spin like crazy through 1st and into 2nd. i need to go back to the track, but its starting to get too hot. im probably gonna have to wait till after summer

 

Get you some MT ET Streets and traction shouldn't be a problem. I launch with little to zero spin with a 4400 stall with 2.5 STR.

 

I have a 3800 2.3 Race converter. Even though it was not designed for street use according to Fuddle's website it has served me well for 15K+ miles on my DD.

 

I also have the $400 Converter its a 3400/2.1 STR I love it prolly the best mod so far,I dropped 2 tenths off my 60ft and 3 tenths off my E/T

 

4000RPM HP series (around $650) for my th400/c5 r headed 434 but haven't tried it yet as i've yet to fire up this new project.

 

I have the 3400 love it. I lost the hard punch it had at around 38 mph, But I lost that dead spot that bogs at 40 - 48, over all I'm happy, and doesnt seem too loose.

 

I have a 3500/2.0 (ish), High Performance / Street
model (the middle one). I bought the base one
originally, had it in the box for nigh on a year and
when the HP/S model came out I decided to upgrade
before installing specifically for the much larger clutch
(being as my whole swap was about getting rid of
nagging clutch slip issues with my other converter).

The performance is something I can't quantify yet,
there is less of a "hit" to the tires as I went down in
STR (2.2 -> 2.0) and higher RPM. This was a deliberate
choice as it's a street-tires car. The car will still blow
them off at full pedal but is more controllable in the
mid-throttle area.

I thought I would come out at a wash for efficiency
by upping stall and lowering STR, it came out close
(96% now, 97% before with the lower stall speed
but also across a headers / ORY swap which puts
some more torque across the converter, so should
drop its efficiency when looked at on a pure slip
basis). Efficiency is still climbing when I shift, this
converter was selected based on the planned end
and not the present motor mods. The shift extension
is pretty near on torque peak and it spends a lot of
time sitting at 5000 before rising up.

I found this converter has a little more vibration to
it than my old TCI, TCI spin-balances (per their web
info) and Fuddle only checks tolerances. So I had to
squash misfire detection to address the converter lock
coming and going. But now that the PCM wants to
lock it up, it locks up solid and my slip problems are
gone. The vibe is not enough to be annoying to me,
just the computer; as I recall I had to bump the levels
a little for the TCI, and this time around I didn't want
to fine-fuss with it again so I just said "kill 'em all".

I can still cruise at 30MPH and 1500RPM on the level,
unlocked in 3rd with 3.42 gears. That makes it still a
"streetable" converter in my book; climbing hills at the
same speed takes 2000-2500 depending on the hill.
Again the low STR came out kind of like I had hoped,
giving me more low-end coupling for the street.

All in all I'm satisfied with the piece, and more than
satisfied with the service and that someone finally
offered a noiseless, hard-holding clutch in a custom
converter at a off-the-shelf price. I wish I had the
time to get a locked / unlocked dyno pull to get at
the efficiency and torque multiplication profile more
quantitatively. All I can say about it is, it doesn't
seem to have cost me performance and made the
car act more like I wanted it to given the way I
drive it. I think how I see "tight/loose" is maybe a
bit different than how others use it. I like the
converter to "slide" the RPM up sort of proportional
to my pedal, getting a proportional torque response;
this converter does it, more of a "linear range" than
the more abrupt, lower 3000/2.2 (which is my only
reference point; I have never had anything like a
big stall, big STR underfoot).

If I had it to do over again I would probably have
targeted a slightly lower RPM (maybe 3200) and a
similar STR, and stayed with the same model as the
clutch is just no-worries. But that would be short-
changing the future, some, I guess (leave room for
the cam & heads, and corresponding increase in the
shiftpoints, someday). It's not meant to be a drag
car, it's more after balanced performance that can
still jump out. In that context I think I picked the
right setup pretty much. Another couple years and
20K miles and we'll see about durability. That's the
other reason I figured, go big on the wear parts
(clutch lining).

Just one opinion; 90% of the time I drive it like an
old man, 9.9% romping on surface streets & on-
ramps, 0.1% track / highway WOT. If every red
light is a timing tree, maybe you want bigger. But
daily driver I think this one represents well.

 

Will the $400.00 converter be able to handle a 150 HP shot of nitrous?

 

I told John about my future plans for a 150 shot and he recommended the performance series ($400 converter) with a 3600 stall. I think it will handle it.

 

Performance 4k here I don't know what the STR is are all of the 4K's the same? Any way it hasn't been in for 24 hours yet so I won't tell you that there is no better out there but I like it so far.
