320bhp N/A 5 cylinder engine - Page 4

6082 was the only grade listed that my supplier could give me for U channel and plate

6082 welds real good and is a strong alloy incase it gets a belt from grounding the sump

AustenW · 11-06-2009, 03:25 PM

Its also nice and strong after the heat cycle of welding

Wow...that thing is going to be a BLAST to drive. In a tiny little Caterham 7? Talk about FUN!!!!!!!!

that sums it up nicely, thanks

costs less and machines better? I can understand why its so common in europe.

For those who are into turbo's this was the engine that I was going to put back in the car before I decided it was too much power for the car

Focus SVT turbo motor, destroked to 1858cc with every mod possible running a GT35

Its an air to air injector from WRC for boost control

I use it to map boost to what gear i'm in

Karl Buchka · 11-06-2009, 04:48 PM

Won't it burn out with no fluid to cool it?

AustenW · 11-06-2009, 04:50 PM

No its an air injector

The works Ford World Rally Cars have been using them for years

If its good enough for a works team is good enough for me

After reading the racecar engineering article I came away convinced the volvo 5 banger (whitebolck for that matter) architecture is the wrong starting point for a 300 hp n.a. engine.

why not, for instance, a honda k24? compact, light, spins like mad, and comparatively cheap. This is the second k24 dyno I looked at, a very easily achieved 280 hp:

I love Volvos, have owned many and will own more of them, think they are a bargain, praise be and all that. But I personally would move to a more modern architecture.

Which, begs a question, respectfully: Why the na volvo motor?

I could not agree more on the sound. I love the 5 banger sound...

AustenW · 11-07-2009, 02:53 AM

Its an all alloy engine and it has the right stroke to make upto 10k rpm (77mm stroke)

Rod ratio is also very good at 2:1

Steel crank as standard

20 valves as apposed to 16v

And the 5 cyl sounds awsome IMO

And no one has tried to do a high power Nasp 5cyl for the road that I know of so I though I'd be different

Are there any potential issues harmonically? Do you have any particular strategies in terms of damping resonances etc?

I suppose they have shorter cranks than the sixes which helps, but I dunno how the firing order etc affect things. Should be interesting!

AustenW · 11-07-2009, 08:15 AM

I'm using a Rattler crank dampener and having the full assembly dynamically balanced at vibration free here in the UK

They balance F1 engines and originally did the balancing for TWR for the volvo touring car engines

You make it seem like your major focus was 300hp naturally aspirated. It that's the case then maybe u should go with the honda k series... just my opinion anyway. IF you're prejudice against honda, you can make that power with a Ford Duratec.

You COULD. Volvo's aren't for everyone. Go back to Hondalandia.

Valvetrain weight is not an issue at those type of rpm's

max valve flow is achieved at approx 1/4 valve diameter, the largest valve six I have managed to fit in a B5 head is 35mm diameter

There were engines in th BTCC running 4 cylinders and similar power with far less spec than that

Sounds like alot of bull**** to me IMO

Also the lobes on those cams only look like 14mm lift as the base circles are quite large

Raceco in the UK are getting over 300bhp out of the new 4cyl duratec engines with oversized valves, and 14mm 300 deg plus cams etc.

http://www.raceco.com/

So...in order to speculate on that, you apparently know the exact CFM that engine was pumping. Which I highly doubt.

That said...so long as you can find a decent set of cams for the whiteblock, 300 n/a should be a relative cakewalk. The engine has enough going for it in terms of displacement and valves. It certainly won't be cheap - I'd HATE to see the price tag of custom cams and full headwork with O/S valves - but it would be easily possible if you had the money to invest in it.

...does anyone even make off the shelf "sport" cams for the whiteblocks? I've never even bothered looking.
