I must admit to being quite excited to find out what happens on Thursday. I hope it goes smoothly and you get the power you're looking for. Knowing how carefully you've planned and done the build I think it should go well. What will be as interesting to find as the bhp is the driveability, but I guess you'll only really find that out properly on the road. How about a video of the car being driven, preferably at WOT?

All the best for tomorrow Nev! I'll be hoping that all goes well :thumbs:

Well I managed all the jobs tonight excet for taking the sump off. That can wait for another day, though I may ask Courtenays to attend to it when it's on a ramp (far easier to spot the leak while the engine is running on the ramp). Thanks for all the good wishes chaps, it's nail biting stuff for me - basically do or die for the engine. I am leaving home at 4.00 am this coming morning to hopefully get there by 9.00 am. Ugg.

Good luck Nev We want all the details, specs, graphs, everything as soon as you know

[The Batman]

Good luck Nev If all goes wrong I got a 19k mile z22se in the garage

[Nev]

Thanks Joe, I could install the Z222ce in my black wheelie-bin to get the power to weight ratio up ;o) LOL Hopefully my new engine will survive though. It seems to run very nicely from 2000 revs and the turbo boosts from 2000 revs also (due to to relatively narrow primary headers).

Best of luck Nev. Looking forward to the results!

hope you missed norwich traffic and it is going up on the ramps right now. nothing to worry about, the level of detail and effort you have put in to this will come good.

[Whiteboy]

Good luck for today Nev. . I hope nipper gives the performance to reward your hard work. Steve

[ChrisS1]

Good luck Nev. You are probably in a Little Chef by now dozing in the corner.

[leevx2.2]

Good luck today Nev hope you get lots of bhp

[Ouchie]

Is it nearly ready yet?

[ChrisS1]

His drive up may have taken 5 hours but the drive back will be a mere 35 minutes.

Well I'm back from CMS (by train) so I can report the good news so far. 1. The oil leak thankfully is just where I forgot/lost a rubber washer on the crank sensor that fits into the block. 2. Jon thinks my 3 ply 102mm to 76 mm 90 degree intake hose will collapse under strong induction at high revs, so will be replacing this. 3. Stephan apparantly laughed when he heard that I had supplied 875cc/min injectors and said that "though he could map for them, they would only allow a minimum idle would be at around 1200 revs and clearly never make it through an MOT emission tes"t. Clearly Niper isn't a race car, so I have followed his/Jon's advice and bought a set of 630cc injectors off them instead which will allow far better fuel control at low revs. Well, anyway after this shinannegens, while I was in the train on the way back Jon rang me back. Apparently the first pull on the dyno made 449 BHP, 450 ft/lbs of torque at just 6900 revs and 1.2 bar of boost (with the Amal valve (which the ECU uses to increase boost disconnected). This is amazing news to me and clearly shows the engine + induction is workings really well, even without setting the timing advance and fuel tabs up correctly. Basically, this is the minimum power that the engine can possibly make which means that they can't reduce the power for partial throttle. Thus Jon is trying to get a far weaker spring to put in my wastegate. This will allow the engine to accelerate less violently, particularily through the important off/on boost transition and allow me to control wheel spin. I am so relieved that the engine has surived the first few pulls, though they havent yet taken it up to 8000 revs. Bear in mind the turbo is theoretically capable of twice that much boost it's hard to imagine quite how much power the engine could make if it were allowed to. I think they will be continueing the good work tomorrow so I will post some updates when I get some more info. Thanks for all the good wishes chaps, it's heart warming N+N

Well done that Man sounds very good to me 449bhp and 450ft/lbs and lots more on tap fcuk me

[chris_uk]

Amazing!!

[Darcini]

I suspect that will be quite brisk on the road, faster even than an Astra VXR. Congratulations to you and Nipper

[KurtVerbose]

allow me to control wheel spin.

Why would you want to do that?

Seriously, that's fab. Really pleased for you, and maybe you'd like to make a start on converting mine now?
