This has been done a few times too!!

I made over 250bhp whilst still running a Standard Head. I had a Stage 3 T3 and just under 2 Bar of Boost.

sorry christian,i know,but couldnt remember and thought id ask while im sorting my engine stuff out on here. so 250?sweet,sounds good enough for a quick car

There are certain benefits to retaining the standard head, such as low down punch. Mine lost some of its low/mid range when I swapped to a Stage 3 head. I wouldn't go back to it as I have gained in the Top End stuff, but I would stick with a Standard head if you want 220ish bhp.

I wont lie, 250bhp is unusual for a Standard Head.

so with a zvh and std head t2 cam i should have a quick car with minimal lag?good good.tbh 250 would be great!but...i aint a dreamer,i wont be runnin 2 bar! itll be 15 - 20psi i reckon. but i dont want to have to repair the damn thing EVER unless i want to!

Ginge !

greg loose the cam mate if ya gonna keep a standard head as the t2 cam is a top end power cam and ya gonna create lag and lose the power band with out it tbh

get a new standard cam and then get 220 low lag engine

ported heads are only a benifit if ya have more air to flow thrugh it otherwise ya lose power


gadget got 250bhp from a standard head and a cam BUT he was runnign more boost

zetecs dont rev enough( in standard form) top benifit the t2 cam shaft mate


good luck though

big_wig_074

ill see what i get,but if its better without the cam ill sell it for what i got it for easy!

Ginge !

id keep the springs though

big_wig_074

oh yeah,deffo! they newer than mine anyway!so theyll be staying regardless!

Didnt think 220 would be possble on std head....and i nearly changed it Glad ive stuck to std now....i only want 200.

What boost will i need to run on std compression to reach 200?

LOADS!! What Turbo?

AndyRST

On a std T3 around 18 psi

MarK4

Agree with andy 17-19 depending on condition of engine

DONT GO ZVH

Lee Reynolds

Engine was rebuilt less than 2k ago, new .5 pistons etc...just std comp.

Hmm, so if i run 15 psi thru the big GRS, ill get no ignition retard as acts will be low, so will i see about 185-190 at that then?

big_wig_074

rad,unlike you i dont really care whats under the bonnet as long as its quick,cheap and reliable!zvh seems the best way,my whole car will probably cost less than a fancy 1.6 monster bottom ended efi thing that u want,and if it breaks ill find another 50 quid engine and transfer the bits!

Ginge !

thats the best way to look at it mate

£50 engine sod that

with forced induction its going in there weather the head wants it 2 or not so i can see a s standard head restricting the power that much

Rick

I challenge anyone to get a proper 250 on a std head on a T3. Christinas made around 220 odd with about 25psi. As a comparison, Dave E's old car made exactly the same power, on the same day, with only 13.5 psi, using a big valve head. My car made 210bhp on a std head on 17psi. I could have had 220bhp with around 20psi. Worth noting though, that these were all very well sorted cars.

Rick

Nope, doesn't work like that. Airflow restriction is the only factor which limits power in a forced induction engine, apart from strength. There is only so much a cross-sectional area will flow no mattter how much pressure is applied.
