Hi all,
Not been on in ages as have been away working.

Will be able to give you an update on how things are going with my engine very soon as mine is due back on Harveys dyno again very soon.

Unfortunatly a couple of years ago when it was last dyno'd there we had a few isues as the company who made the inlet manifold made the back plate out of 2.5mm plate and not 5.0mm as we had specified.

It bent like a banana and we had a massive air leak!!
End of session!
Since then Ian has re-designed the manifold though.

In 2003 it made 325bhp and 321lb/ft at 3020rpm@23psi

Since then though it's seen some radical changes.

As soon as it's dyno'd i'll let you all know how it went.

 

Gus didnt yours make 337bhp on the engine dyno?

 

wat about mine we seen 345+ bhp@22psi around 7 years ago

and sevenvalley was doing 320 bhp

the good old days

 

That's mad. What car was that in? Can't remember that one.

Engine dyno'd or rolling road figures?

 

jamsports blue q plate rolling road 300+@wheels first to do 160.9mph

daz from severnvalleys grey s2 320bhp rolling road


my 1600 302bhp @wheels rolling road

 

God yeah. I almost forgot about Jamie's car for a second.

Can't wait to see what it goes like when he's finished it with the new spec engine.

 

didnt severnvalley use the lean burn head with good results ?

 

yeah rads



337 on dyno before now

 

yes valley used the lean burn

i think the black zvh they did was pushin 350-370bhp @2 bar

 

what abut the one thats tuned by tommy field, white series one with T4 turbo thing its over 400 but not to sure? thing a guy called tom owns it from essex?
