View Full Version : Had the 9 on the rollers today!
And i'm pleasantly surprised!
Expected something like 250-280 bhp but it turned out to be 300 atw @ 0,9bar :D

And with a measured 10% drive loss turns out to be 330bhp atf:

Needless to say i'm more then happy with the result!
Although it could use some more timing around 4000rpm but for a first time hometuned car i think there's nothing to complain about!
Time for more boost :D
great job arthur up the boost and see what the score is matey:wasntme:

There are 8 less things to drop into the engine. :laugh:
Awesome:agree: i need to upgrade to a 16v
Nice work fella :)
Your using stock Williams cams aren't you?

Stock willy cams and iwg 56,5mm gt30.

Damn, good results then fella, also annoying for me as our specs are very similar and I'm 50bhp down :(
Correct the list if I'm wrong but you've got

Williams cams
Log manifold
Gt3071r-wg
3" turbo back exhaust
Charge cooler
Forged rods and pistons
0.9bar of boost
330bhp at the fly

Megane cams
Log manifold
Gt3071r
2.5" turbo back exhaust

Are they that different in terms of lift and duration?
Iirc meggy cams are exactly the same as 16v cams,
So for F7P it is 268/261 with 9.28/8.54 lift and for F7R it is 274/264 with 9.87/9.25 lift.
Don't mind the duration as it's probably measured at 0 lift but the total lobe hight is correct as i've measured them myself too.
However don't be mislead by a dyno printout, who says the dyno i used is correct?
Could wel be 300bhp but then still you miss a few horses.
My ignition isn't tuned btw and it's running pretty rich so could well be i'm able to gain a bit more on the same boost.
What ignition are you running? I'm having some misfire issues atm....

Now that's interesting, I've measured my megane cams and a set of 16v cams and the megane jobs have way more duration and half a mm less lift on the inlet cam.
I'm using a wasted spark coil pack.

Not necessarily.
It may simply be that you love man balls in your face?
Ever thought about that?
You guys are so nice to eachother :laugh:

Sorry about that arthuur, I couldn't help myself :laugh: If you have ever spent time with Oli, you will know how he forms a central gravitas for abuse.
Back on topic now.:agree:

anyway, it aint the cams as I said the other day, all that will do is shift the power band/spool up or down the rev range slightly, your still strangling the exhaust gasses with that .57 housing /60mm wheel;) all though I wonder if the willy head with the bigger ports is /better than smaller ports of the f7r megane head, for outright flow :)
and all rolling roads figures vary :D
great results btw tutur:smokin:
I will get on with mine again once I have refurbed my house, I miss my Renault:sad:
