highstall

[projectxf]

hey guys anyone know much about highstall as im interested in puttin a 2500 highstall in my auto i need some good info b4 i do it if its easier add me on msn ridnlow_xfstyle@hotmail.com

prices range from 400 to 900.

just ring a few different companies and ask them about it, they'l ask for a few specs of the car or fax you a spec sheet, fill it out and send back to them, they build the conveter to suit.

[TUF250]

epens on how much work you have done to the car as well and what you want out of it.

my auto which is a rebuilt BW40 has a 2000 stall in it but unlike the standard stalls which you cant feel lock up, this one feels like a switch is thrown when it hits 2K and the thing comes alive. makes for a good launch with the bigger cam

[tuffxd]

found 2500 great behind mild 250 with 2.77 rear heaps more launch but still kept all my top end. what rear end gearing are u opting for as 2500 is nearly on the money for my power cuve and also what type of camshaft are u running or planning on running take it all into consideration before choosing

[projectxf]

im running 277 but might be changing it to 323 lsd or locking it up or minispool wateva is best as for cam im stock atm but i will go to a stage two dynotech as ive heard there great to run... well my planz for the engine is shaved the head, polish the intake ports, stage two cam, extractors and 2.5 exhaust an dats pretty much it.......

[ltd351t]

2500 off the shelf unit would be fine IMO

[TUFE]

Should go niclely, mine goes fairly hard with 8.5 comp. Where did you hear about that cam hahaha!!

[Tiapan]

i have a 4000rpm one, its pi$$ing rain here and i just got back from the pits....hahaha the licence inspector says my car is too "loose" in the wet....drives sideways in slow motion.

highstalls are the best! i love em, the way they deliver instant power on command is great

[PSI_LTD]

question for you people: the turbo in mine comes on pretty low. around 2000 rpm... the c4 i'm putting in has a stock 2000 rpm stall. is this ok or should i get a higher stall converter?

Its perfect i reckon, you dont wanna have to muscle it in the wet. With a higher stall it would be a real handful in the wet

it'll probably work fine, with the TQ from the turbo its going to flash higher anyway, it might even flash too high depending upon how your engine behaves.

[Tiapan]

yea course im from rock...i drive an xf dont i?? hahahahaa havnt seen me round >:(

well hit me up next time your headed to the foreshore for a cruise and i will see ya down there.. whats ya car look like??

[TUF250]

i have a 2000 stall, i love the way it locks up, very positive compared to the stock one. its a good match with the efi cam

[maidenfan]

I've never driven a car with a stall converter. Are they really a handfull in the wet? I was going to put 2500 in my turboed ute. I work night shift twice a week, the last thing I want to be doing at 6 in the mornig after a 12 hour shift is fighting with my car.

[xeghia302]

aha, white xe ghia v8 that i just bought still stock condition, and a silver ed fairmont, low, chrome rims, exhaust etc

[projectxf]

who cares if there a hand full in da wet more fun i say lmao do it

[Tiapan]

oh yeah heaps of fun in the wet,

you might have seen my other car it this one...

another thing you should know about highstalls if that generally whatever size stall you get that is what the car will rev at at 100kpm what ever yo do (if you get a biggish one) keep it cool, always use a transcooler and a temp gauge, in my opinion manuals are for learners and real men drive manulised, shiftkitted autos, they fu*kin rock!

[projectxf]

im thinking of fully manualising it but its not worth it in the end cuz i can jus shift normally

[projectxf]

can i fully manualise it? or do i need someone to do it

[Tiapan]

you need a ful manual valve body, im pretty sure it makes the box stronger and the changes instant, takes the brains out of the gearbox which is good

[projectxf]

i should be able to do it myslef yer?

[TUFE]

I wouldnt worry if it wasnt a C series. Plus it would make ur car only marginally faster

[lowxdute]

I have the stock quoted 1800rpm borgwarner 40 torque convertor and are soon going a highstall. I have 3.5diff gears and around 140rwhp now through the auto so the stock convertor although OK is a bit doughy on take-off. The 3.5's however are unreal with the 3speed auto gets to 0-100kms very well. I'm looking at going somewhere between 2400-2700rpm stall. Revs at 10 in D0 now is 2860rpm! With T5 is was 2230rpm in 5th! Can't wait for the take-offs...

[Tiapan]

goodluck! you wil enjoy a 2400rpm one!

[xdcy8]

Hey guys can i use a highstall in my car as its a manualised auto so will it work and what size stall would be ok for my car xd 351 the guy i got it from says it has had a lot of work done to motor but im not reall sure i was thinking 2500- 3000 stall would be ok what do u think

cheers
al

[ltd351t]

yeah 3K will be fine, really as long as the stall speed is in the cams operating range, you'll be sweet.

[1tuffXD]

my XD 351 has a 3500rpm stall. good fun but not the best for stand stills.
maybe because its a loose convorter or what, im not sure

cruising on the highway is a bich too, revs at about 2700-3000 at 100kmph.
with stock 2:77 diff, but its worth it.

mine is a dominator convorter.

[TUFE]

**** i didnt noe stallies affected revs at 100

[XF0747]

shouldnt effect it that much

[1tuffXD]

it all depends, if you start going up a hill it can stall right up
to whatever your stall is,say 3000

how much load the cars under, ie: full car of people and
a full tank of fuel will get the revs up high.
the more load the higher it will get too until it reaches
the end of the stall

[RUN12]

What do you guys think of this one then. I have a turbo XF with a C4 and the convertor is a dominator set at 2500. The choice of cam is what i'm worried about at the moment because i've gone for the standard EFI replacement which makes power from 1500 to 4300 or there abouts. The turbo pretty much kicks up as soon as it hits 2100 and is absolutely on it by 2400. I use the standard 2.77 ratio gears and i'm just wondering if i should go back to a lower stall speed or change the cam to a 2000-5000 type. My issue with going to a bigger cam is that i'll have less vaccum at idle which in turn will stuff up the map sensor reading. I'm torn between which way i should go.

depends when your turbo spools.
eg.
if it spools at 3000rpm then its really pointless having
a standard stall or a 2000rpm stally coz u will have turbo lag.
try set your stall as close to where the turbo spools at.
even a bit higher is always good coz then u have 0 lag.

so in your case 2500 is perfect, u stall it up at the lights.
turbo starts boosting at 2100, by 2500 its spooling great.
let the break off and no lag.

if u have a standard stall u will take off and have heaps of lag
then the turbo will start to spool at 2100-2500 and then the power
comes on. that will suck majorly.

i would only set a stall for a cam if it was for a NA car.

[RUN12]

That i'd have to agree with, thanks for your thoughts. I'm going to stick with the standard cam and leave it with the 2500. I can always change it if required.

[hypoesp]

You must run a decent size cooler with a hi stall or the auto will burn out. For a car that sees a fair bit of freeway driving you need to have your revs at 100 k's close to your stall speed or the convertor will be slipping all the time and create lots of heat. eg: my car has a 3000 stall and at 100 with 3.5 gears revs at 2850 so its almost locked up..

[ltd351t]

yeah exactly, you want the converter locked up on the highway, especially if your doing lots of driving, can be hard to do tho, with turbo cars as they need the tall rear end gears, but still need moderate stall speed to get fast take off, so its harder to acheive.

good turbo converters are similar to those used behind centri blown cars, they allow decent flash rpm, but couple up heavily on the top end, and if they get it right it will still drive fine when not under max load, so many variables tho also, with turbo and how it behaves.

[RUN12]

I think i'll just put it in and see what happens. The other things that concern me are how the modulator will operate with the turbo. I'm guessing that it's just going to rev out in every gear as soon as the turbo starts making any amount of boost.

[lowxdute]

If you have a 2.92:1 diff then that's about 2400rpm at 100km/hr. If you went a 2500rpm stall and do a fair bit of highway driving it'll be fine just sit on 110 you'd be doing 2640rpm and off the stall.

some peoples experiences and opinions vary on this, with mine, at light boost it still changes normally, but when you matt it and boost is more than a few psi it will hold gears or drop back if it can, just behaves like it should really.

Only comlaint from me is my setup chokes before the shift point, so its kind of anoying.

How did you go with the transducer, does the original borg item fit in ok? The other issue i have is the dump pipe fouling on the dipstick, i've thought about just heating it up and bending it into shape or just making one out of copper pipe and using stainless steel stranded wire as the dipper. It's become a real toss up between leaving the standard auto in and changing over to the C4, it's starting to drive me mental.:weirdo:

[PSI_LTD]

if you use a c4, you can manualise it, so it shifts when you tell it to.

I would dearly love to have it this way but my missus drives the car as much or more than what i do, unfortunately she don't like the idea of that word manual. I'd rather not spend the extra $400 to make it this way as well if i can get away with it.

[hypoesp]

Just put a tci or b&m street/strip kit in it, it will shift harder but still be automatic when left in drive.
