Everyone swears by catcam 708/743's and the other usual suspects are Newman ph3 cams,but there is others.

All depends on your budget and what's available at the time of looking.

Then you need to factor in having to get a remap to get the best out of them,with the ph3 and catcams you get a lumpy idle on std timing marks and also run the risk of running lean at higher rpm.

You could try and solve this by fitting a 3.5/4 bar fpr but for best results and peace of mind a remap is better.

You could fit combination cams if a remap is out of the question,these use a Newman ph3 inlet cam and a ph1 exhaust cam.They aren't as wild and with a 3.5/4 bar fpr you should be fine at higher rpm's.

There is a set of these for sale on here,also a set of Kent cams iirc.....cams come up for sale all the time.

He was trying to be a smart arse by correcting your spelling mistake,but most times when the phrase high lift is used,its written down as "hi-lift"......

He's obviously got feck all else to do,or is that "fuck"....:y:

708's/743's get my vote, don't forget the mapping side of things and you'll need to increase the rev limit to 7800-8000rpm.

I mind you saying this before dave and I don't get it......

I can understand raising the limit if peak power was at say.....7800rpm but even then I'd expect the 708/743's to have increased power/torque throughout the whole rev range,or at least from 4k onwards to the current limit of 7300 or whatever it is.

So surely they will be beneficial regardless of whether the limit has been raised or not??

[Dave_P]

When I'm on track my engine isn't below 6.5k rpm, it spends most of its time between 8-9k rpm where the power is.
I'd suggest you guys would be looking to keep your engine in the power band as well, if you keep the std 7250rpm rev limit you won't ever see peak power as it is at 7500rpm with those cams in my experience.
You want to be able to rev past your peak power.
Std cams peak at 7000rpm, rev limiter is at 7250rpm, seriously, don't waste £ on cams if your not going to up the rev limit.

I see it that way as well and of course you you don't want to be below 6.5k but I bet at 6.5k the aftermarket cams are producing more power than the std cams.

Does anyone have two separate graphs we can look at?,would be interesting to see what the power is for both cams from 6.5k onwards to say 7.2k rpm.

[jimmyson]

would like to see this as well

That run if I read correctly is on a std engine that's running a full saxsport system,raceland 4-2-1 and induction kit of some sort.
