IS it worth fitting a performance Cam to the FRST engine i want to be running near on 200BHP. So far i have got myself some Low Comp pistons and i might be fitting Motorsport Valves to someones recomendation . What else would i need to do to get this sort of BHP?????

Thanx

[Ian C70T5]

I wouldn't know mate

[Ian C70T5]

what boost you going to run??

T3 Turbo?? if so what stage hybrid or standard...?

Be careful..

for example

I have low comp botom end and Stage 2 T3 and Piper T2 cam and i have bad lag under 3.2k and kicks and then kicks again at 4k..

[Andy.B]

You get about a bit don't you Ian Well i am just about to phone SCS to conferm how much i should skim my pistons down by and the T3 is a S1 one I think its about a stage 2 its got cut back blades,360 bearing, -31 and a larger housing. havent got a clue what boost i will run cos the engine is in bits ATM You have seen the piccies It will be uni-chiped and set up on the rollers.

[Andy.B]

PS have you got SCC's and SCS's phone numbers cos i cant find them????? LOL

[chumkila]

i would uprate my cams if ur gona hit over 200+. but then again what do i know and im usually wrong!

[Fezzy Turbo]

Skimming pistons!!!!!

I see your not going for reliability.

You will also need a larger I/C or chargecooler, 701 injectors, uprated fuel pump, new uprated clutch.........etc........

[Andy.B]

I am aware of the fact that i will need a bigger IC, injectors, and clutch. As the engine stands it a blank canvas totally standard and in bits. All the bottom end is out all pistons everything.... The head as supplied by Project (thanx Al you are a saint ) is just a skeleton no cam tappets, valves except inlet valves. As you can see i am keeping my options open to tuning possibilities. Plus everything that gets replaced is either New from Fords or Up-rated performance jobbies. I wish to extract 200BHP out of this engine and i know its possible to keep this engine reliable at this BHP if you do things right .

So ppl i am open to sugestions on what to get for my engine.

Thanx

I can remember reading earlier this week on this board that the standard cam is good enough for high poer unless ur running extremly high boost. Im not sure on the details and i may be wrong, but it may be worth checking before spending cash. Hoipe it helps, even though it probably wont.

[Ian C70T5]

Mate..

Get a Piper T2 Cam.. because its best suited with the T3 turbo.. Also Cause you're lowering the compression, you'll find that you'll get a lot of lag..

[Barry.t]

Does any1 know how much boost and bhp a standard camshaft can handle???

cheers

[Andy.B]

Nice one Ian glad to see that you are still here to give me advice Looks like the spec of my engine will be running closley to yours

Thanx

[Fezzy Turbo]

You will need a complete bottom end re-build, you say you have the low comp pistons, so thats a good start
You will need a fully gas flowed head and a T3 which you have.

Your main worry, is cooling. The Pace chargecooler works, but it can be made to work even better, that way you have less heat and more power for less boost. Or you could use cossie I/C's.

Making your engine reliable at 200bhp needs good cooling, a well built engine and a good set-up.

[MadcatCraig]

I wouldnt skim CVH cast pistons compression at standard is 8.0:1 unless ure running high boost lower compression is of no use ! forged items from mahl is what Ins@[ERRR] has i think dunno wot ians got.
are you after driveability or numbers ? if its the big 200 ure after low comp and uber boost will get you there but as Ian said laggy and will drink the fuel !
Ull need a uprated in tank fuel pump also cossie or aftermarket number will suffice.
If ure using the XR2i head from Als engine there are a few mods which would be a good idea so it can get rid of the gasses quicker ie porting and polishing.
As for cams again it comes down to driveability or numbers i havent got a uprated one in my car but from wot i hear there an arse at low speed and rpm.

[daz]

i have a piper 285t2 in my fiesta with a 165 chip on it, not at all lumpy as people said it would.
as for skiming the pistons to lower compression then go for it, but only some thing like thirty thou off, as recomended to me yesterday by ian howell , but hey what does he know,only got the fastest fezzie around.

[Fezzy Turbo]

DO NOT SKIM CVH PISTONS!!!!

The crowns are too thin. Cossie pistons are fine and thick and can be skimmed, NOT CVH!!!!

You want a thick a piston as you can get for reliability purposes.

[MadcatCraig]

daz fezzie is right ! im doing a zvh and skimming my zetec pistons ! its also ok to skim forged pistons ! but not standard CVH ones as they are prone to get holes in anyway! !!!

[Excursion]

8.0:1 - is that what RST's are as standard?

If so then I wouldn't want to lower that much more, a quality conversion aklways makes good power with little boost.

I think Id rather have a really good job done on the head, large valves and portwork done by soimebody who knows the CVH (ie dave at pumaracing) t3, really really efficient cahrgecooler or intercooler setup - the GRS one for example. afterall lower charge temps is more power for (basically)free!

Get a decent exhaust system, I dont know figures for the standard cam but for driveability Id see how far you can take it. Lag sucks!

you could get away with running 15psi at 8.0:1 with the right mapping, surely this would give close to 200? but figures arent important its torque curve and how its drives really. maybe I jsut talked crap cos I admit I dont knwo the CVH that well

[Excursion]

oh what are con rods like on the CVH?

[snake]

WTF+LOL

compression on a turbo is 8.2-1 standard!, pistons are forged Mahle as standard, do not skim the pistons+i`m running 196 bhp@0.9 bar boost on standard comp!!, the boost will be upped to 16/17 psi depending on what act temp i get at 16 psi, at the mo it runs at approx 30-35oC. The engine has now done 8000 miles of normal and thrashing!!, and its revs to over 8000rpm!!. I wouldn`t trust the bottom end for more than 220bhp, after that then steel it..

[Excursion]

jolly hockeysticks was right

[MadcatCraig]

Snake ure the man but my haynes manual says the compression for a FRST is 8.0-1 and Phil M telles me its 8.2-1 or 8.3-1 for a ERST !!!!!

hey i only typed wot i read ! also forgot that standard tubby pistons were forged but CVH ones still see holes in them !

[snake]

That will be a Haynes manual that also tell u to put one of the gearbox mainshaft cogs upside down!!, they even showed a picture of it!! LOL

And pistons only blow due to crap engine builders or crap mappers.

[Project]

Oh christ what's all this bollox?!

[MadcatCraig]

Snake talk to me on MSN please !

Me = ammateur i learn by what i read in books and from other ppl !

anyway heres the proof im not speaking out of my arse ! Mr Haynes may be but not me u decide while i gather more berries for breakfast

[Project]

I think the point to remember folks (and one I guess I could learn from as well) is that reading up and actually doing are two very different things, and until you have done both it might not be the best idea in the world to consider your knowledge "complete".

Just a thought.

/Al

[snake]

And here is my copy of Ford technicians product training manual that i dug out:

[MadcatCraig]

well im glad thats cleared that up as i was going by the haynes manual for wot compression to run my ZVH at only require a .6mm skim now!

[Andy.B]

Right then i suppose that Snake is the man to talk to about this thing aswell. Would you chat to me on MSN and give me a clue on what to do please???? I have built engines b4 but not a Turbo one and i dont know what way to jump with this one . As i said i would like a nice fat 200 BHP.

Thanx

[Barry.t]

I'm in the process of doing an 1.8 zvh conversion myself and i was advised on the rsoc to speak to mark @ BSW (sorry cant remember the number), he told me that you can safetly run 1bar of boost on the standard pistons WITHOUT having them skimmed!!
