so many 'storm' names , thanks to you both, yes Peter tornado is the chip, my mistake and yes Tim hurrican is the cam I was quoted, so its still looks like the the 218 then ....just need to put the money aside after the damage inflicted by a large service and steering rack rebuild ...........just one more !! heard about a piper 270i cam, where does that fit in the scheme of things if you don't mind me asking again .

Piper 270 is softer than kent 218. a popular cam but IMO the kent is the one.

mmmmm I have just been told by someone that the Viper Hurricane would be the best cam to fit in my 350? What sort of thing can i expect from it as you say its not really suitable for TVR. Would I be better fitting a different type Tim?

Typhoon, Tornado, Hurricane etc. These are Real Steel cams (or 2 of them probably are) and pretty good to but tame. My money is still on a 218 or for a bit more zip a 224. I ran a lot of Rover cams through a dyno software programme and the 218 was really good.I have used the 218 and it's ok.

After much thinking and discussions I had come to the conclusion that the 218 was the way to go for mine. However like most things there always seems to be something that catches your eye, I looked at the spec for the 224, being between my oem 214 and a full blown wild 234 (well for a 4.0 it would be wild ).
But wasn't too sure if the standard non-pocketed pistons could accomodate the lift associated with the 224 .
Experience has shown in the comments from the likes of Tim, that the 218 is a better all round cam than the 214 but do you have any graphs comparing the 218/214/224 as this may help me finalise my finacial outlay which is looking more like sooner rather than later :roleyes:.

What area will it be tame in compared to the 218? The one I was looking at was the Hurricane.

I don't have the specifics to hand as this was some 2 years ago. I put some 30 grinds into the pc and stuck with the hydraulic grinds. I missed off the high lift items if there were concerns over valve pockets. I just felt the 218 came out better overall then the rest within stock rpm's. My next bet was a 224 and I think it to will clear the pistons (best to check) but on this particular engine we went with the 218.

Sorry Harry, didn't "dig them out" until today, trying to find graphs on TVR (or near) spec engines, They will be waiting for you tommorow.

Duncan, I have read your cam report on TVR Bristol and it is fascinating. How much running in do you need to do before being able to get a rolling road report on power etc? Does this mean your engine is still a SEAC engine rather than a V8 developments type?

Cheers
600 or 100 miles depending on who you ask.
However, I'll wait a bit till after I get the other tweaks done so that the top end pulls harder.

It's still not Griff 500 quick, but not far off the mark and once the top end is sorted we'll see....

I'll still class it as a SEAC engine. You wouldn't make a SEAC engine simply by dropping in an H234 into a non SEAC engine - would you?

Duncan,

Any update on the power output of the blue beast?

Sorry - no.....
I'm still recovering from my last bill before getting more work done. As I've said before, I just need to get the top end free'd up a bit by sorting the exhaust and replacing the injectors. The Inlet Trumpets can wait till Christmas......

Having said that - it's still very quick at the moment. I'm now learning that I can overtake without screaming the engine; it's more relaxed and saves that 'will it, won't it' nail biting gear change whilst on the wrong side of the road.

I'm not going to bother with a rolling road until I've done at least the exhaust and injectors.

I would recommend being very careful in cam choice and not going too wild as it will definitely have the end result of making your car undrivable. My 350i has an RPi Fast Road Cam. This is reasonable as it still allows the car to tickover reasonably and has given a benefit in performance. The lumpier and longer duration the cam the less tickover will be available. No problem for track days but at traffic lights not very amusing. The other side to this can be your emissions. A very high duration cam will allow more fuel through at tickover not getting burned and could result in a fail at MOT time.

The 404 has 'better manners' than the 234 that most SEACs have. So infact it's actually a bit too civilised for a SEAC

It's a relatively new cam design and I'm also told that besides the smoother idle and beefed up mid range that the cam profiles reduce noise from the solid lifters.

The 404 cam is still supposed to be a screamer - but my engine has something strangling it at high revs. I'm really looking forward to sorting it out and hopfully it won't be too long......

In my experience The 404 has the same top end punch as the 234 but more low-mid torque, more civilized at idle though,
just spoke to a customer who fitted a 404 to his SEAC curiously he claims that the 404 is fare more "cammy" and more top end punch than his previous cam , not sure which cam it was though.
incidently he will be at Mania this year to join the SEAC crowd.
