you CAN use solids on hydraulic cams but they will wear quicker than on a solid profile.

The solid profile has a much gentler ramp at the beginning of it generally, to allow it to take up the clearance (typically thats about 10-15 thou depending on the engine) and the absense of this will cause:
more noise from the valve train
more wear to the cam
more wear to the lifters

 

I'll just stick to a new set of hydraulics then, I'm not wanting to have any cams made although I have no idea how well the xe cams will work with my turbo

 

XE hydraulic cams on solids is what im using intially, why not wait and see how mine wear first, lol

Anthony was on the same with no problems I beleve, but check with steve.


There is extra wear, but its not significant enough to worry about so much it puts you off using a particualar grind IMHO

 

I'll see how you get on Chip, I've got a while yet before I start worrying about that

 

My original plan was just to run it in on these cams and start mapping it, then to swap to some hotter ones, but TBH based on how well its going so far, I think im probably going to stick with them, so I should have a good couple of thousand miles on them by the time its an issue for you. So I can soon whip the cam cover off and have a good inspection of the lifters to let you know how they have faired (not like it matters if the cams themsleves wear a bit quicker when they are cheaper to replace than an oil change is!)

 

Looks like a mountain of work, good luck with it this time

Btw We found that several of my GT30 & 35 engines are on 99 blocks and not one failure, that includes Porkies which has been abused on track for about 4 years.

 

No, non. Porkie's bore is slightly bigger than yours too.

 

Lee's ran a GT35 for 3 years but is now on a GT30, lot's of them have gone down to a 30. They will all be going for a GT32.5 soon

 

Tell us more .

 

Tell us more indeed Martin

Come on spill! and can mine be changed!

 

 

Automated reply:

CUNT !

I'd make an educated guess that it is supposed to be a half way house between a GT35 and a GT30, so a true 550bhp turbo?

When will you have the airflow figures / first one to test?

 

Mike would like to know the full spec so he can source them and put them on his web site and sell them for a tenner profit for his hobby and then moan that he makes no money out of selling parts
secret cams and secret turbos are the way forward

 

Mike can foxtrot oscar

Btw I'm just stamping up a load of standard cams with the special secret profile numbers, do you need any Tony?

 

Actually, I'm not a good enough businessman to do that, as I won't tread on other people's feet in this regard . Unfortunately for my wallet, I have too many scruples / morals....

 

Charming!

 

that's not what harvey says lol

 

Got a stack of standard cams myself good idea Martin I am thinking of calling them SSS (tripple S) cams,Secret Spec Standard lol

 

pmsl

 

I somehow don't think Harvey would complain about me stepping on his toes .

 

he doesnt complain about you doing him up the arse, so why would he complain about stepping on his toes

 

Now you know why I carry a milk crate around with me .

 

Lots of good info on this thread - you guys drinking too early in the morning?

I am currently enjoying a snifter or two of bourbon - but it's nearly nine at night.

 

are these genuine cams then?these SSS

 

the 'gt32.5 sounds interesting and certinaly some thing which i would think about,

 

You have hit on a few truths there Mark cant beat the laws of Physics but he can & does get his engines nearer to optimum than the others you mention. He does give one of his silly grins when he hears the head/cam design of his rivals all working to 1980's rules. Unless they have a bit of lateral thinking they will never cure the surge/lack of torque problems.
It aint all Marks ideas but others tend to use the wrong fount of knowledge

 

Welcome back Rod

 

whats these cams all about then?or is it a wind-up?

 

what inlet is rod using ??

 

ahh ryt so would you use one if your inlet proved to be worse on the dyno ?
cheers
