Not certain there, reading this and other articles certainly makes me want to stop putting money into this thing, HP per £ from here on is going to be stupid


Mate, get it on the road and drive the bloody thing! :D

Tell you what chaps I just ordered some exhaust rap I was going to try to get the rear clam on but I had better wait till I rap the manifold otherwise it's going to be a pig of a job. I am spending the day doing all those small bits that need doing, your more than welcome though to nip over and tell were I am going wrong

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 : Imnotworthy Imnotworthy chinky chinky :groupjump:


Curious to your inj. duty cycles, as running the VXR 470's at 4.5 bar pressure (making them ~580cc/min) should getting close to maxing these injectors with 380BHP @ ~12AFR...

Now do and make that thing driveable!!

Got the rad back from pro alloy this morning and it along with the charge cooler rad are back n the car, changed the lower rad piper as it was looking a bit old. I wrapped the exhaust manifold and u bend, don't think I will need it but a bit of overkill shouldn't hurt So rear both clams can go back on, bad news though back to work :( tomorrow I aim to get the clams back on the car Saturday, Techieboy said he could lend a hand Imnotworthy

An inlet redesign needn't be too costly. If you consider making a casting that is a mount and plenum for the SC mounted low down by the sump feeding into a tubby style CC then into a cast inlet its two new castings. Prototype castings can be done easily enough by lost foam which can by patterned by CAD (if you're handy with CAD) for not too much. The actual casting would be fairly cheap too. Minor facing / drilling etc would see it finished. If you wanted to cast multiple runs then you'd be better going for a wooden pattern and casting in green. It costs a touch more for the patterning though but you could recoup some on selling the set-up. If you pattern it yourself it'd be even cheaper! Care would be needed with the inlet manifold as boosted charges tend to cause uneven cylinder pressures when the manifold is fed from one end. I'd suggest looking at the inlet on the turbo'd FPA cars....but then I would! Do it, you know you want to!

I would like to but CAD is a bit out of my league I am afraid, I will keep my searching up in the States

The CAD is the easy bit the hard bit is measuring everything it needs to interface with and avoid accuratly enough that you can have confidence that you can make it directly from the CAD model and it will all line up and not clash.

Nah, we got the rear clam on and sorted a couple of bits but Nick wants to have a play with the front clam and splitter, whilst it's off. So next weekend. Maybe. :unsure:
