Clive cams 805 profile ground at 105° separation

294° duration, 7.5 mm lift.

Great thanks, I'll speak to them in regards to that profile.

Is this close to the 'Wade 140' specs
couldnt find the alternative cam specs section in techwiki

dhadina, Tell Clive you want something around 232-236@0.050", .300" lobe lift on 106 centres. Tell them it is for an A series but if you want to get keen you can ask for a maximum of 25 inches per second seating velocities @ 7000rpm and a maximum cam profile velocity of 6.5 thou per degree. You don't want a dual pattern for a road car, the extra exhaust duration will loose you low down torque and is only really needed for top end power. Not worth it for a street motor.

Found it

This is one of Clives
Might be abit big for a stock bottom end on the street though

One thing to also consider is what gearbox are you using, if this is a street car, the stock boxes drop 2800 between 2 and 3rd so to aggressive of a cam will make life miserable with a stock box.

Surprised nobody quoted the Nissan rally grind numbers after all Rally cars need torque and flexibility same as road cars and when all said and done the people who designed the engine should also be the ones who worked out what cam grinds are the best compromise as when all said and done every cam is a compromise.Nissan Cams are measured at 0.5mm compared to the US 50 thou standard when trying to compare figures.

That is why we now have variable cam timing and lift or both on modern engines and formula one does away with the cam totally by using very fancy electronically controlled solenoids aided by air pressure systems to give infinately variable cam timing and lift in some test mule engines, Even BMW is experimenting with such designs for road use in the future.

In the USA if you have deep pockets I know who to talk to and it will be something very special but the cost will also be special and it is not one of the known Cam Companies but those in the know in Nascar would know who I am talking about those engines are engineering masterpieces and Formula One does not rate compared to wht has been achieved with those dinosaur engines.

Wade cams were the supplier of choice for Gibson Motorsport and Australian GTR's were the best in the world under the rules and ran Wade cams not Nismo, So ring Wade and talk to them and no I don't know anyone at Wade, But their reputation is well founded as being the best Australian Cam people.

I do know a bit about Cams as when I was an engine builder and machinist we were one of the few people with a "Cam Doctor" a now long gone pioneer in Cam Measurement equipment, There are a few companies who supply good gear to do the same these days and Andrews cams in the US makes one of the more affordable Cam measurement systems, the other Guys Adcole who make the Rolls Royce of Camshaft measuring equipment are unknown to most people because they generally supply only Manufacturers with a few exceptions one being the US Company I alluded to.

If your supplier does not have the right gear to measure Cams then they cannot guarantee their grinds are what they should be either, I measured grinds from a number of suppliers and frankly maybe they ground their cams by dragging them around the block behind the shop ute in some nameless cases.

While I agree with your sentiments about Wade Cams, sadly they closed their doors to business on the 28 Feb 2014, they are no more

Clive from Clive Cams use to work for Wade - nothing lost for now

Nah, F1 still use conventional camshafts. Variable valve timing is not permitted. The Pneumatic part is the valve springs, not the actuation.
