Hi what sort of max power are people getting out of there 1.6 cvh

gus

iTrader: (1)

Not sure what power stu Collins ended up with but he was getting massive power from his

dodge8283

Didnt NMS also have a very fast cvh?

Fordmad!

You see a few few 250s about. Personally unless you have deep pockets id just go with 200ish fast and more reliable. If your going for massive power there's better engines out there to do the job id say

jay030787

I am hearing around 422 Bhp Ish is that about right

jay030787

Am running around 300 now so want it flat out lol just wanting to no what the big power one are using like water meth and things and management wise and I don't want a better engine I want to keep it a 1.6 cvh

Karl @ FPT

It's all about how deep your pockets are.... IIRC NMS have achieved just over 500bhp but it's so extensively modified it's a far reach from the original CVH.

jay030787

I no lol I have deep pockets just want to talk to to someone who has one to see some of the specs is anyone on here running water meth

Karl @ FPT

NMS use a custom crank, rods and pistons into a relined Duratec block (IIRC) to bring it back down to 1600cc, they then extensively weld the head and re-machine it to achieve the desired flow along with larger valves etc, a custom NMS profile cam is ground by Newman with solid lifters, then it's manifolds and a suitable turbo, finally mapped by Karl.
I think last I spoke the cost was around Ł6000+

StephenC

Simple fact of the matter is the blocks are just too old and weak now and nothing can be done other than go with a more modern block (zetec for example ). No two ways about it at 300+ it can't be reliable and you'll constantly be waiting for it to split. I could no longer live with that so I've gone with a new one.

russ rs

On low boost 😂

So what's seen as the limit of the standard block and crank nowadays? 260?

Chas

From what a specialist told me it really comes down to the condition of the block thus the question is "How long is a piece of string?". He was saying that he is seeing many blocks that are now becoming brittle due to age and also down to how thin the walls are on a 1.6 CVH. The 1.9 is not meant to be as bad in this respect and neither is the Zetec bottom end.

I am running 225BHP on a ZVH and it has given me enough grief, albeit over silly things. I have done around 5-6k in it this year mind you, probably 3 times the amount it has done since the car was finally rebuild around 4 years ago and the engine 2 year ago (I'd have preferred the 1.9 long block to have stayed with the car but hey ho...).

I keep thinking about which route to go on my fiesta, want cvh as good to see when you open bonnet as looks original but the blocks being weak puts me off a bit on weather to low comp it or go zetec route

jay030787

Am running around 300 Bhp on mine with no issues or reliability issues if there built right without cutting costs there fine am running 27 psi just wanting to no if to move onto omex and water meth I want to keep going with this engine to see what I can get I no it's a 1.6 cvh but that makes it more of a challenge

Let's get a group but on alloy blocks

gus

iTrader: (1)

Should find out what mine is running soon

Last time round was 340+ bhp and over 400 torques

jay030787

What management are you running and what spec

gus

iTrader: (1)

Std crank ish
Proper rods and Pistons
Fully worked head with steel billet cam, roller rockers
Field motorsport spec Rolled bearing turbo
Jenvey throttle bodies
Ava exhaust manifold
Dry sumped
With f88 rs ecu

Roughly

jay030787

Ok cool what power is that at what boost

gus

iTrader: (1)

342bhp 405 ft/lbs @ 2bar

jay030787

Cool I need to get mine back on the dyno see what mine is running now at 27 psi did your exhaust manifold make any difference ? And what size exhaust you running

jay030787

What size exhaust are you running

gus

iTrader: (1)

3" right through

gus , wat rolle rrocker u using , did u start having same problems as me ?

gus

iTrader: (1)

Not had any problems mate.

Just changed to see if they do what they say on the tin

turbotrev

Gus your car is the bollocks mate, one of my fav RS turbos ever.

I had an NMS 1600 cvh for around 7 years and it gave me no grief at all and was 100% reliable the whole time.
Was 300hp and 300 torque at just under 2 bar boost.
I loved it.
Weak point as already mentioned is the blocks.
I had a thicker walled series 1 cvh block in mine and it was as good as gold.
I was gonna take the power up further and change the spec but instead I sold it to fund going the Cosworth route.

Cheers Paul

iTrader: (1)

Thanks dude

jay030787

What management are people using to get the big power I have cosworth management at the moment but not sure if to get the ripped off and go with omex just for ease of mapping

JK12

iTrader: (1)

Speak with Karl - Frenzy Performance

He installed boost monkey Gen 8 for me - Fits like a glove and top work!!

jay030787

Do they go straight into a cosworth loom

MarK4

I had 270bhp on kjet in 2002 with zero issues although i did use a 50 jet of nitrous. I saw stuarts at jamsport and it was a epic build and very light weight

Chas

What Escort did you have? . I have my reasons for asking .

My car is not a powerhouse by any standard. Years ago it used to make 270BHP from a 1.9 long block using KE-Jetronic and a 5th injector. It is now on a 1.8 ZVH making 225BHP. IMO there is a little more to come from the car (the charge temps have been reduced since the last RR and I am not convince the cam timing is all that on the car) but we shall see. I certainly will not get beyond 240BHP with the above tweeks IMO. It is still on the above injection setup running well for the best part, albeit not perfect (the fuel pump needs 'priming' via the ignition key for it to start first time if left for more than a week, the cold starting (from dead cold) could be better but the cold start injector is not wired up. I want to check the wiring before simply hooking it up to rule out a few things (i.e a bodged loom).

Gus, that looks like a lovely build and it sounds like it has the spec to match. It would be interesting to see the full spec of it. That must really be a flying machine!

Rsturbo519

I like your style. I'm doing the same with mine - at 270 just now but going for more this winter.

What's your spec?
I'm looking into roller rockers just now ( what's your thoughts on them ) can get them for €330 in the states

Blair

Rsturbo519

Hi Stuart what issues are you having with roller rockers?

I'm about to buy a set from States ( from a 1.9 cvh but I'm told they will fit ) ?

I have a newmans cam and solid lifters - will this be ok to use the roller rockers? I would like roller lifters but sounds a lot off hastle

Many thanks
Blair

stuart collins

iTrader: (7)

no problem with roller rockers , sorted out all my problems , mine are made by titan

Rsturbo519

Thanks for reply Stuart. Are you able to tell me if the 1.9 cvh roller rockers will fit 1.6 head?

And if I can use them with newmans cam and solids?

Any help would be appreciated

Cheers

stuart collins

iTrader: (7)

i use a newman cam and solid lifters , ive seen the american rockers fitted to a 1.6 cvh , dont no if they went straight on tho

Rsturbo519

That's good to know. What do you think I can rev to safely?

My spec is

Wossner pistons
Pec rods
Newmans cam and solids
8.5.1
Roller rockers
Big valve head
Standard matched manifolds

Would it be safe for 7500?

Scott_Rst

Im no expert by far, but pretty sure head spec would be fine for 7500rpm,,
My cvh head on my zvh was still on standard rockers at 7620rpm BUT no guarantee it would last very long! Actually the stud holes for the rockers where modified! Which supposedly makes a differance,

You should speak to harland sharpe in the states for roller rockers, i was speaking to them about a set before i decided to go zetec turbo
