dyno on sat wot will i get????

[L12A GN]

right my rx7 will be going for a power run on sat lets see if anyone can guess the correct bhp............

1993 mazda rx7 efini
53k
had its rebuild at 47k
apexi N1 cat back
apexi intakes
blitz bov

wot should i expect?

[John Yorke]

How about 265fwhp? if the rebuild is good you might see a bit more:wiggle

[grinder]

i would expect about 260 ish - they are about 255 as stock

the intakes might get you a few bhp ??

[sadgoth]

ok so what do we win if we hit the exact figure? ;)

I'll start with 258fwhp

[L12A GN]

are they 255bhp @ wheels stock?

[Frankie]

No that's the flywheel figure for early cars.

And i estimate 265 bhp...

[nikp]

Should see standard ish power figures, as everyone else says. 255-265 if everything is in order.

[rmagictastic]

no, you will see 263.5 at the wheels.

Rmaj

[gsb876]

I say 268.7 @ wheels :Laugh

[shaunwil]

Im saying 264.8 :p

Shaun

[ScuttleRX]

I'll go 221 @ the wheels:bandit

[peterwolds]

231.5 ATRW (approx :wiggle )

[mikeyh]

where you going lisa?

[L12A GN]

dastek its my local cruises dyno day on sat afternoon pop along if you can make it we can have a gab

[Rixio]

228-230rwhp :)

[L12A GN]

is this the math for whp > bhp?

whp x 1.4?

[ScuttleRX]

Think general figure used is an 18% transmission loss, so I normally divide whp by 0.82 to get a rough bhp figure

[rmagictastic]

sorry, just a power run!!!

oh right gunna change my mind then, 246.8 ATW

[Jono FD3]

I've got similar spec and I hit 265 at the fly last november with the clutch showing slight slippage at 5k!!

[L12A GN]

[L12A GN]

220 @ wheels
242 @ fly

the stock ecu does run slightly rich....but with those mods you should have been seeing pretty decent afrs...the dastek dyno do give pretty low readouts though...

[grinder]

i always thought they did the runs in 4th gear - so a near 1:1 ratio ???

[Eeza]
