Surely the easiest solution (not even that easy) is to redesign the intake manifold and retain the existing CC setup?

The benefit with that is you could flog a whole load of them to cover your costs.

it's nothing to do with the design of the manifold it's self it's the fact that the laminovas are not sized for the flow or heat that people are throwing at them, it is working well beyond the design at stg 2.

I think around the 380-400mark is right anything more and you are getting dangerously close to liner issue... I tested when the rods and pistons would snap and I defiantly am not testing the liners!!! I have a few ideas about cc systems so once I'm up and running I can tinker about with then

You could always use my charge cooler rad; 50% more capacity than the Pro Alloy set up.

i dont need capacity as of my large coolant tank the radiator area is still the same as my pro alloy one

No it isn't, the surface area of mine is greater than yours however your willy is still longer (I am told).

No it isn't it is the same size actually. Or is mine wider? Yup, I think mine is wider.

no just has bigger headers

And a bigger core.

[The Batman]

yeah thicker core i maybe changing to a standard radiator so that i have an inlet outlet on each side as i may run extra radiators....

[NickB787]

it did seem to lift a bit on the rollers!, what gear do they use third or forth? it showed 138 I am wondering if they have removed to limiter on the ecu?

Think they use 4th. 37mph to 138mph all in one gear. Covers most eventualities.

[NickB787]

should make overtaking a bit easier now

[techieboy]

Lovely SC torque "curve" again. What clutch are you running in there? Will be interesting to see if you now start running into the problems the >Stage 2 tubbie boys do. Though I guess the SC delivery is a bit more clutch friendly than a sudden massive dollop of torque.

[NickB787]

It's the Courtenay uprated clutch that has been in the car since the original conversion 6 years I think, I am hoping that because the torque is almost a straight line I won't have the same issues that the tubby guys have

Amazed to see the outlet manifold not turning red when it's peaking

[Nev]

If you have a Helix or Sach paddle plate and cover then you will be fine for way more torque. And as someone has already pointed out, you SC chaps don't push transient torque peaks through the drive train, so it's way more clutch friendly That dyno graph should make it a complete pussy cat to drive around when you go out shopping to Tesco Whats the idle set at and is it lumpy? Is the car to be MOTed and taxed BTW (ie a road car as well) ?

[PaulCP]

The last set of figures to come out were 377bhp and 304lbs at 7300rpm on an 80mm pulley. Temp in the dyno area was about 20 C.

Think i will leave it at that, peak power was about 7300rpm, inlet temp reached 60C so realistically if I want more than say 390bhp I would be into some extra cooling of the intake manifold itself as even extra coolant capacity would just delay the inevitable.

Mapping was MUCH easier with the z20let ecu my 470cc injectors worked fine and weren't maxed running 4.5 bar

so all in all VERY please, well done Courtenay :

Well done Nick finally got there

i think my wife is going to hate you when we get back it will be all your fault

There is no turbo 'bottling up' the exhaust gases, so it's not normal to see the manifold runners glowing unless it is running super lean. Also, you can see he has big I/D on his runners and a good design which all helps flow the gas straight out.
