How Long Will It Last

[southside]

My cars running 326@15psi.... the same as my mate matt on here (spoolax) we both use Bruce hienrich, the guys a god! I drive my car pretty hard as well

its a stock BA bottom apart from valve springs... getting a new tune 16/17psi and see what I make, then ill run a 20ltr E85 tune mixed with 98ron, be up in the numbers there

no war mate its all good.

if I recall, a cheap fix would be drop the sump, pull the rods and pistons out, and JUST replace the rods. I dont know many people who have done this though. Usually for piece of mind people swap the pistons to....but they dont stop there!

At your level it is HIGHLY recommended you run a surge tank +044 pump. This is how 90% of BA motors with 330+ blow (like mine). Put one on!

A little bit off the original topic but does anyone know the approximate cost of the in car rod / piston change?

Thanks,

It can not be done the way it has been described to you.

Sure it can, you just need too support the engine and drop the whole front subframe out of the car.....heaps easier than pulling the engine....

[ratter]

and dont worry about compressing rings to put through the bottom of the block, just leave them out, less frictional drag.

Thanks for the reply Ratter... Thought it sounded too good to be true! I guess ill be looking at F6 short engine or forged when the time comes

if yours is still intact, it may work out cheaper to rebuild yours and it could be stronger than a stock factory short

I have a piece of string, how long is it.....?

Too many factors can influence the answer too your question.

Driving style,fuel,tune quality etc etc etc

2 inches, no wait - 3 !!!! oh wait 3.5 !?!?

this is something I know a bit about!!!

I currently have a 4spd ba xr6t making 330 odd rwkw daily driven, 380rwkw on my drag tune which is occasionally street driven. Soon to be making 400rwkw... hopefully!!!

I have had my car just over 4 years now and bought it 2nd hand with 45000km on it. it has now done 116000km

my car has lived with 300+rwkw for 3.5 of those 4 years, most of them sideways racing someone.

I reckon in my car's lifetime that I have probably done at least 250 passes at the drags.. the majority of the passes were 11.6 or better. currently running 10.9@126mph..

my stock gearbox lasted 6 months making 310rwkw, though it did not have a trans cooler and I was not afraid of ripping a skid here and there.

im currently on gearbox number 6. A built 4 speed will last me 14 odd months before it starts making noises with my car making 330rwkw+. once it does this I stop driving it until I can afford to get it rebuilt.

I have smashed 2 rhs cv's at the drags. 1 was my original std cv which went out of the blue at the drags.

and my 2nd was due to launching my car with 18psi off the line.

My engine has never skipped a beat, though I have never skipped an oil changed and it is always changed every 7500km or earlier.

My engine still has perfect compression after 65000km making 330rwkw daily driven!!

as to how long components are going to last, here are some tips to help extend their lifespan:

- dont down shift your 4 speed auto (engine braking) they dont like it and doing it will kill it really fast!!

- if your doing a static burnout, dont hold it too long in 2nd gear!!!

- dont be doing power slides all the time!!!

- keep your oil changes up with quality full synthetic oil ( engine and trans)

- instal a trans cooler for your auto

- dont be tight with money and mods, it might cost more to do it right!! listen to your tuner!!

- try and stick to the same service station

- dont drive on your max hp tune

last but not least, a decent tuner will do wonders as to how long your engine and gearbox are both going to last!!!!

Dammm you spent some coins on your btr!

So you spent 4k on each gearbox rebuild?
