Had the 9 on the rollers today!

[Tutuur]

And i'm pleasantly surprised!

Expected something like 250-280 bhp but it turned out to be 300 atw @ 0,9bar



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

[R5MJH]

great job arthur up the boost and see what the score is matey

[Dre5gtt]

Great stuff what you running to get that power

[TNT ANDY]

Brilliant stuff Arthur, simply stunning work.

[Tutuur]

Thanks lads!

[DaveL485]

Excellent!

[B18ftMOJO5]

Wow nice performance figures. Must be a handfull to drive. Well done mate

[Dre5gtt]

Cool good old enigine that f7r never let me down when I had my Williams

[rs250nut]

f7r 16v turbo f series engine the winning team

Why have 8 when you can have 16

[TNT ANDY]

Why have 8 when you can have 16

There are 8 less things to drop into the engine.

[Brigsy]

Awesome i need to upgrade to a 16v

[Os8472]

Nice work fella

Your using stock Williams cams aren't you?

Gt3071r ?

[Tutuur]

Stock willy cams and iwg 56,5mm gt30.

[Os8472]

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

F7r Williams 2.0ltr
Williams cams
Log manifold
Gt3071r-wg
3" turbo back exhaust
Charge cooler
Forged rods and pistons
0.9bar of boost
330bhp at the fly

Mine
F7r megane 2.0ltr
Megane cams
Log manifold
Gt3071r
2.5" turbo back exhaust
Charge cooler
Forged rods and pistons
1.0bar of boost
284bhp at the fly

Those megane cams are killing me I'm sure

Are they that different in terms of lift and duration?

[Tutuur]

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?

[Tutuur]

You guys are so nice to eachother

[GTphil]

Not necessarily.

That's one of the best posts I have read in a long time

See now that's interesting cus I'm sure TNT Ross said you loved his tiny testies resting on your face

[TNT ANDY]

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

Back on topic now.

[HAndy]

(chin)

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
great results btw tutur

I will get on with mine again once I have refurbed my house, I miss my Renault
