Are you sure that worked steve? As I thought I read that failed....

Go E85... Chemical cooling and high octane = 400+ easy. @Joe; fit a ZZP themal gasket before they start mapping your car.

there was an intercooler design that produced less power compared to standard

Freekin awesome news!! WRT liners - I thought the 400 bhp limit was obtained by adding nitrous to an NA engine and seeing what broke when. Nitrous is hard on a block so boosted power should be OK over 400 bhp. I've seen 600bhp banded about somewhere. The problem ultimately is the block design with the unsupported cylinder barrels (the actual liners are fine). At high power they are going to move! The original fix was a deck plate that was found to crack the end of the block. Also a copper head gasket with locating fire rings has been mentioned (not sure myself). An audi badge style support might be interesting?? I'm interested to see how the later block fixes this problem. WRT inlet manifold - I'd considered casting a box shape and bolting it in in the sump / cradle area with the SC on the outside. The outlet could feed out through the drive belt into the drivers side sill area for a charge cooler (tubby style) and back into a twin cone plenum (FPA style). This would move weight down and give potential cooling benefits. I just haven't had time to pattern this lot and I cant justify the time on R&D if it doesn't work. WRT - ECU, having heard about some of the fixes to make it work properly I'm not convinced its entirely 'open' although writing out the cam sensor is kinda good for us. I'd like to see it calibrated on MAP readings and bin off the MAF.

Great result Nick - Hope you're happy?

GET THAT SMALLER PULLEY ON AND BEAT JOE TO 400BHP!

(slightly worried that Joe's VX pulls more than the Trev! :s only talking BHP mind! )

I am actually, my original aim was 370-380bhp and we are bang on, shame I spent money on a couple of extra smaller pullies but now we have it running I know that they will just not work without some serious extra cooling ability. I could ask Jon to try them and I know first/second runs they will get over 400 no problem but why bother if they will drop down due heat soak

will upload the dyno plot when I get it

Congrats, I can't wait to drive it

@Joe; fit a ZZP themal gasket before they start mapping your car.

But then you also need MASSIVE injectors and to E85 proof the fuel system. Also its limiting for when you cant get E85 so easily here... I know Morrissions claim to sell it but its rare.

[Exmantaa]

Same here in Holland with the availability. But it's has become a lot cheaper recently and there is 1 pump about 5km's from my house, so very tempting to try what it can do.

[Whiteboy]

Fantastic result. Nick already looking for more grunt. Steve

Could an air conditioning system not be modified and replace the water with freon in the inlet manifold?

[Nev]

I would imagine that reliability would be better than squeezing an extra 20 BHP out of it surely ?

Depends on 'power consumed to cool the charge' vs not using aircon... And also getting the heat out of the refridgerant, I've been calibrating a system where the outside temp sensor is mounted above the AC rad and when just applying a little cooling effort (from 18deg ambient to 16deg demand) the exterior temp sensor soaks upto 35Deg in no time. So piping that will be a mare and you might end up less efficient than a plain water setup

And as Nev said (which is odd ) why risk things for about 7% extra go at the top end?

I tried this years ago on my GB motor. I used two lockheed missile heat exchangers and plumbed freon through it. I used a climate control system to dial in ICT. Unfortunately it struggled to cool the volume of air that was required and it was absolutely flogging the pump etc etc.

Thanks Steve

I had thought of something like that myself yet again though I think we are looking at a completely new manifold design. Wet water to start with I think and a larger tank .If I can come up with something to keep the temps down I may well go higher but till then I will have to cope with what I have. I would of liked to have done the 400 on the z22se but that might have to wait a while.

That was one of the reason I said just leave it where it is rather than push 7500 or higher. Although E85 is great I want to be able to just stop anywhere and fill up won't be much good on a Europe road trip.

This is one of those, if it worked people would already be doing.

I still find it amazing that we are talking about a car here with a stage 2 SC converstion + the power of std NA on top

Yeah, but you gotta try!

[Muncher]

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.

£200 manifolds group buy anyone?
