You delta guys are missing out by boost ramping the ZFR. Me (kappa) on the other hand...

No boost ramp ZFR

RWD

????

Profit

 

I agree. but a boost ramp really makes the ZFR even usable with power. it spools so damn fast anyway.

 

I am pretty sure you still use the LSJ/LNF FW and Clutch


except you just need the f23 clutch pipe and bleeder block. The line from the clutch master to the bleeder block is confirmed to be the same in the f23 and f35

 

Good to know, thank you.

 

What clutch?

 

how is it possible that a f23 will hold that kind of power better than the f35? is it built that much better. I have one sitting in my garadge

 

hope mine don't break. on 27psi with meth got a good boost ramp and don't give er till past 3krpm have done a bunch of hard pulls. also have torque tuned down. most of the time I drive normal though. not to hard driving unless tuning.

 

Not sure but a lot of higher hp turbo LSJs are running them after blowing F-35s and Even a few F-40s up.

 

Only four I can think of running the f23

 

to much crap to change to run it. lets hope mine lasts lol

 

its not that much more to change if u are already doing the trans

 

This and compared to a 4.45 trans F-23s are nearly free. I see them for just $200-300.

 

F23's are getrag transmissions, with shorter gear ratio. So they hold power

F35's are Saab transmissions that are based on a 25 year old design. Coupled with the LNF's 3.82 gear ratio causes issues with high torque, high horsepower cars. I notice that more people blow up their tranmissions when they use six-puck clutches.

 

My finial drive is 3.84... good for turbo cars

 

F23 in my 09 which is geared longer, vs 4.05 F35 the 23 is shorter in every gear up to 5th for the highway which is nice but won't be as good in a longer race then.

 

Would anyone have a lsj tranny for sale or know of one for sale? Lol I think I'm just going to go that route.

 

How are you guys breaking 4.45s..... I've had my 4.05 swap for 20k miles now and the block let go before the tranny, and still going strong.

Im curious as to the internal design of the f23 since GM rates the torque as NM. Wonder why they rated it low.

F23 = 230NM cap
F35 = 350NM cap

 

broken f40? this is the first im hearing of this...what broke? im betting it was just syncro related which would lead to my next question...What clutch and flywheel was used?
