View Full Version : Profesional opinon
After many heated decousions i was convinced on using my 22 spline drivshafts and 1.6 inner cv's but after speaking to someone today he said if i did go for that option they would just fcuk up virtualy straight away am i best to just go the full way and get uprated shafts and hubs any ideas Cheers Karl...:thumb:
do you actually want a professional opinion, or just one off a forum?
I run 22-spline shafts with 200(ish) HP, plate diff and slicks.
I havn't snapped a shaft (yet) but have knackered an outer joint this year. I must also add that my car gets given death round a track for 80% of its time running. Make your own mind up.

It was a attention grabber lol well i think ill try it that way and if no luck go all the way Cheers Karl...:thumb:
Just out of interest who is your professional up in Leicester? I used to live up there and am just wondering.
Theres a local bloke called Shane Golding [ SGM motorsport ] and a chap who i know who owns a mk2 astra the cleanist around Karl...
I don't believe that I've met him.
However, I would run with the tried and tested route of 22 spline shafts with the cav / nova cv combo.
Maybe he's heard about Phil's shaft shearing antics.
22spline shafts/cv's are used on LETs too,, so there fine.
the only reason that they brake is normally that your engine isnt quite sat right in the bay

Or they are Mtech ones & destined to break at some point.
Ususally break with lots of lock on and lots of power!!!

yea one of my mates with a 280bhp LET nova snapped one of them of a quater mile run last year!

this shud work no problem i have been told off loads of ppl that my car wouldent last 2 mins i run f13 box and t.d shafts on my c20xe and i have had it on the road a while now and hav had no problems so 22sp shafts sud be ok
cheers all of you :thumb:

22 spl shafts are fine with big block motors.

Well it aint gonna last 1 second cos you aint fitting an F13 to a C20XE
Used 22 splines on my old XE, and it was fine....

what dont understand what u meen you aint fitting an f13 to a c20xe? i already have fitted one to mine and drove around for months with it on
Interesting. I think Stu is getting at the fact that they dont fit. So how did you do it? No more nails? lol

Ive snapped two shafts on my old nova, one was a supposed unbreakable one that went within 5 mins of finishing the conversion lol. The other a GTE one which snapped at pod on the line.

lol from past experience (not on mine) its normally the machined down hubs that split on them not the actual shafts. Either way something breaks.
Also im running normal corsa ones on my LET and ive only broken outer cv's, broke the splined apart clean off in the hub. An I normally launch in second gear with almost no pressure in the tyres, fully on boost. If they were going to break they would do it then.

you kno you've got some power when u can do that ;)

Barney rubble stylee!!
So how did you fit the small block box to a big block engine? Without SERIOUS work??
You may have an F16 but not an F13!!

I dont under stand why people use the F13, its a proper rough **** way of getting around not fitting the different shafts, which lets face it isnt hard to do.
F13 wont fit an XE though will it?
Philsutton
21-12-06, 09:22 PM
yes but you have to rough a*se it for no benefit, only one that springs to mind is so you dont have to change the shafts.
Hmmmm
Every days a school day
But an XE with 130lb ft torque ish as standard, it aint gonna last long?!?!
Philsutton
21-12-06, 09:38 PM
they more torque than that tbh, and yes it wont last long. If you drive like a girl and dont actually put any power through it then you could probably have it on for 300 years with smashing the **** out it.
Right, just out of curiosity, i ave an F13 with a cog out through the bottom of it, the wee alu plate, is it repairable of clean ****ed?

all you have to do to fit an f13 box is get the fly wheel redrilled so 1.6 gsi ect clutch will fit the boxs fit no problem its just the xe clutch is 2 big well i have known of one person that even got an f13 ova the big cluth and no i dont drive it like a girl and i also run nos on my nova and it is still fine plus put a nova with an f13 box agenst a nova with f20 ect the f13 nova will kill the f20 nova up to about 70mph and i know this by racing other valver novas

Well get you! Arent you just the greatest engineer in the world!!

LOL..... All that cash spent to run a half ass box and small shafts....
Next you'll be telling me 13" 3 spokes are back in fashion along with lava lamps
My point exactly why pay to machine down a clutch/fly, when its prob cheper tof it an F20!!

at the most ?30 quid for inner cv's (cavvy mk2 ones)
Use the nova shafts and your off.... If you want one thats slightly quicker through the box them go for the f16 c/r (close ratio one) i bet there wont but much of a difference between your 1400 sr box and the f16.
Whats the your thoughts behind using the f13... cheaper??? quicker??? EASIER???
Im struggling to come to terms with it.. Dont worry... il still sleep tonight! LOL
Gash, thats the reasoning!!

was all of cheep and easy for me cos before i went self employed i was building puma challange cars and the lads there did all the work for me so yes it was easy and yes it was deffo cheep
rather just the thr 22 splines, saves a lot of the work to be honest
ill be using the 22 splines for mine next year - and an f20 box lol

Easiest and best tried and tested proven way!!
can we try and use the english language a little more professionally please.
the F number USED to relate to the sustained torque in NM/10 that a box would take, go over that number *10 and you shortend the life of the box by X ammount... eg go upto 260NM (Sustained) and youd halve the life of the box (assuming you launch politely)... and since no one knows how hard our boxes lives have been then there is no safe guess, nor is the "life span" that gm ever envisaged for these boxes.
More recently the F number is purely that, a number to identify boxes... the torque limits have gone all over the place
I am using F20 gearbox and 22spline gsi shafts and 1.6 cav inners try my luck at that and if all that goes to pot ill try uprated ones... :thumb:
Use ^^ that method Karl, you'l be fine..
lol f13 + 20xe lol
I'm puttin a f25& cossie flywheel with a S15 clutch on my 1.2 turbo,with nos lol

Was going to say that, if its all about closer ratios then use the F16cr box lmfao, not all f13s are cr by the way. So its not like saying a F13 box is better acceleration as it clearly isnt.

mine is a cr box and box has been strip'd and rebuilt before it went in

my seh ran a f16cr box on 22 spline shafts and during its known lifespan to me it only ever had an outter cv i know its not got the same power as an xe but i gave it some serious crap. pod,autotesting,backroad thrashes and 5000 miles in 6 weeks!
