I've been reading a few different posts on this and there only seems to be snippets of info here and there no real.definative list of what is required to accomplish this. So for you experienced folks do you think you provide me with a list of parts required and if possible the model of where I can find said parts

Cheers

Dave

Ps what cam.options do.you have with a 2.1? Same as a normal rs?

Couldn't of asked for a better reply thanks alot

what kind of price are you talking? what manufacturer also? you may have a buyer for two sets if they're good...

can the pistons have longer skirts to be more of a road piston than a race type? heavier yes but longer lasting.

14-1?!

e85?

cool, 88mm is very risky though.

I can get pistons and rods for around 14-1500, would be CP and farndon or carillo.



Dave, the cams you can use coild be much wilder if the pistons are designed properly, however you need to take into account the limitations of the standard valve springs and hydraulic tappets, I don't recall the exact peak lift but its around 10.5mm, peter Taylor may have it on his website.

tappets depend on how severe the ramp angles of the profile is and the rpm, however with more cc and good component package choice these engines wont need silly revs to make power, and will have much broader torque.

meaning less fuel, less wear and tear, also ultimately a faster car, less stress on clutches for example (ive seen more and more reports of stress fractured pressed steel pressure plates on high rpm race engines)

sandy hasnt had any problems with cp rings afaik, nobody else on here use them??

My 2088cc engine *only* revs to 7800.

The way the engines build on circuit I'll always be in the gear above than my mates 205 which is a cammed 2.0 gti6 205 on bodies. The mid range torque that my engine produces makes it much faster to be exiting a corner at 5,000 and getting the drive rather than being down a gear screaming it at 7,700.

And probably sandy has locked the drawings too.. But it doesn't matter anymore
Its not specific peugeot but other ppl who drive other brands. And right now im trying something that no one i know have tried before. This could be as bad or worse, or better. I'll find out

280-300 hp (flywheel) on e85 sounds about right

Once again I'm lost lol e85?? What is this? When you talk about 88mm crank what part are you referring to? With regards to shells do you use standard pug items? If so do I need mains for a TD and then big ends for a RFY? A standard headgasket? Or is an uprated one advised? I can build an engine when I have the parts lol its just making sure I have the right parts do I need to do anything to the block? Sorry for all the questions but I'm still learning with the 306

Dave

Nope.

On circuit I'd say 80% of overtaking is at the start of the straight after a corner. Utilising the healthy extra bit of torque

The easy way to explain it is;
Power;
hp = w = J/s (the constants doesnt matter right now)

Torque;
Lb/ft = Nm = J

In the end horsepower is torque over time with some constant or factor.

More revs = more "Pushes" over the same amount of time. And if we make it very simple and u have a flat torque curve you want to rev as high as possible to accelerate as fast as u can.

In the regular equation that you can convert torque to power you need the revolution because that's your time-factor

Yeah, That's some other things. With higher revs and fuel you have to think about a lot of other things and that's not what I'm talking about. It's always about compromises.

What I wrote in my last post is just the simplest math and physics behind torque and power. You can't have one thing without another. That can we agree on.

When you drive your car you don't change gear right after peak torque.
With higher peak torque you have a higher amount of power at that rev if you compare with some other engine that have a lower torque. But that's not just fair.

If you have two engines with the same amount of horsepower but one have higher torque I would take the one with higher torque because it will have a flatter power curve

Edit; I'm not going to argue about sandys engines, he have found the perfect compromise it looks like. I haven't seen anything from sandy jet either

Edit2; and why did 306 maxi rev to 9800?

Our engine builder told me not to go beyond 7100 rpm on hydraulic tappets as they float too much
