Catless, 3 inch Full tullet But the synchronous rings does not like shifting at high rpm. I am tired of repairing the car!

 

Also do'nt understand the F23 gearbox can cope with the high revving set ups from the sc builds....Especially the Saab ones...Noticed there almost no faillures with these builds....

 

Turbo's F23 's are failing the most....(2nd gears), (mine included  in previous set up)

 

Thougth the revving killed these boxes? (and very high torque,like NEV's one, but he still drive's it )

 

I know, when driving my speedster on track, my box will be death in a year (probably faster)

 

So, better lower numbers and longer lifespan so you can enjoy the car, totally understand it....

Chasing numbers = chasing troubles

The best thing in destroying the gearbox is the fact that i can add then a quaife 😃

I think my gearbox has survived as I drive in a pretty mechanically sympathetic way and also I have very smooth delivery for the last 3 years.Lastly I only use 340 ft/lb most of the time, so that is no more than the stage 4 VXT's do.

 

I guess if you track your car you are trying to wring every 0.1 second (or whatever) per gear change so the gearbox won't like it as it probably isn't designed for super fast changes.

Torque kills gears, while speed can kill roller bearings if the heat isn't removed. Keep in mind that the F23 was designed for a range of applications, so it's likely that a mild increase in max RPM isn't going to push the bearings outside of their operating speed.

Synchros went in my NA F23 the year before last and it has pretty much only been used on track or fast road. The engine is pretty much revved to it's limit on track and I think that this is what killed it.

This is my AP2 to rear axle adapter. It's made from aluminum and light with 267gr each.

Have you thought about trying the standard z22se cams over these stage 1 cams

[ufods]

i thought the stage 1 are some better then the z22se.

[CHILL Gone DUTCH]

im not sure tbh 

but remember something about comparing the z22se cams and the stage 2 cams and there was not a huge difference between them 

 

and with rich (400-500hp) recently making huge power with his water meth injection car on some uprated na cams it was just a thought 

 

is the standard internals of the 2.0 quite high ??

sorry, i do not understand this?

[CHILL Gone DUTCH]

sorry i mean the compression ratio quite high 

[ufods]

i believe 9,5:1

[Exmantaa]

B207 = 9.5:1 compression indeed.

 

ZZP Comp cams:

 

ZZP S1 is 210/206 @ 1mm and 10.78mm/10.69mm lift, 109 LSA ZZP S2 is 216/218 @ 1mm and 10.78mm/10.69mm lift, 111 LSA ZZP S3 is 216/224 @ 1mm and 10.78mm/11.10mm lift, 113 LSA

Stock LSJ is 196.5/191.7 duration @ 1mm(.039") valve lift and 10.04mm/10.04mm total valve lift. LSA is 107.5

Z22SE has same profile as LSJ cams, only timed differently.

[ufods]

that sounds good to me.

[CHILL Gone DUTCH]

 

 

if you seek more power I would advise you get some zzp stage 3 cams

Has anyone tried the stage three ams yet vocky ?? that you no off 

 

 

most had stage 2 zzp cams, but after the 550 bhp Harrop engine my suspicions were proved right, that the mild cams are the cause of the sub 400 bhp power limit and not the inlet manifold.

 

That engine had stage 3 NA cams, not the milder zzp stage 3 cams.  

 

 

 

sorry i got it wrong, i thought i had read that the NA cams on richards water meth project were mild, but it turns out its the stage 3 zzp are mild           

[Exmantaa]

Not sure which Comp Cams he/Vocky had fitted in that 2.4 engine??

[oakmere]

I would say they were the 113400 stage 3 NA

[vocky]

they are indeed the 113400, which are 264 and 268 degree

I though these figures were at .050 lift  ?
