The standard lifters will pump all their oil out and the springs go coil bound if held above 8000rpm for even a short period of time .
My new engine (and the one on the T66 thread), which will rev to 8500, will be on solid lifters and Cosworth DFV (old F1 spec) valve springs .

Fuck revving one to that. No need really in turbo form, even at well over 500bhp.
And to make it give useful power that high up at well under 500bhp would mean losing you out loads of low down power, so the powerband size dont change really, making it totally pointless

Thats a predicated figure at 2.5 bar, but he has only run it at 1.7 bar so far.

Steve,
I'm hoping to fill in what I expect to loose response wise with having to run these cams, with the Mountune roller-barrel inlet, and if necessary, 3.9 gearing to sharpen it up further. That way, I "hope" to get thebest of both worlds (obviously the slight increase in capacity will help) .

What did it make at 1.7 bar?
Boschman, I think you change your sig to "a predicted / guessed 600bhp saff"

I dont like the thought of them over 8K myself either, ive gone for solids for my engine (LET not YB but extremely similar) was just saying its not quite as dramatic a sudden death as some people may have read your post as meaning.

Garage19......its a MAD built engine for that BHP and all cooling etc is taken care of..it will run 2.5 bar no probs...although i may not go that high..probably stick at 2bar.
My sig is exactly what it would be at 2.5bar...regardless of wether it will break...its all there its wether i am man enuff to run it at that!
No different from saying i got 700bhp DYNO figure..incar you aint..same as rolling road figures..my ASS dyno tells me what power..remember i am part NMS aswell

It wont be standard bottom end if it has:
S rods (and isnt an S)
A centre mains strap
A balanced crank
A hotter cam (well its in the bottom end, LOL)

@ 2.5bar regardless of wheter it will break??
That means i can say the stock 2ltr zetec i have in the corner of my shed is a 400 bhp engine because i'm sure it would make that if i rammed 2.5bar down its neck..... regardless of if it will break
So what did your engine make at 1.7 bar? Why don't you stick that figure in your sig until proven your figures!

...the diffrence is mine is built to take it and everything is in place..its only a turn of my boost controller away
As for my sig..its my sig and i can say what i like..i may put it to 700bhp with race fuel.

..... and change your name to billy bullshit!
Can't stand people who make up their bhp figures without ever testing them. Maybe you should go and work for TVR!

I think when she pointed over at you and your car and said "there goes peggy now, capable of doing it in 11 seconds" it wasnt the car she was pointing at..............

I think the extra 2 seconds is cause he has to whack it off a bit first to get it up if there is a girl about
